This wraps the ALSA core jack detection functionality and provides integration with DAPM to automatically update the power state of pins based on the jack state. Since embedded platforms can have multiple detecton methods used for a single jack (eg, separate microphone and headphone detection) the report function allows specification of which bits are being updated on a given report. The expected usage is that machine drivers will create jack objects and then configure jack detection methods to update that jack.

By hardcoding the accepted device-ids (last hunk of the patch) I'm trying to avoid regressions because this driver will otherwise load automatically and not let snd-powermac load. People who are unhappy with snd-powermac and have a device-id property in the device tree are encouraged to read this patch and make a patch to amend this as appropriate.

This increases the maximum size of the kernel before we get link errors significantly. The problem here is that we don't have a "call"-ish pseudo-instruction to use instead of rjmp...we could add one, but that means we'll have to wait for a new toolchain release, wait until we're fairly sure most people are using it, etc... As an added bonus, it should decrease the RAM footprint slightly, though it might pollute the icache a bit more.

This patch adds support for configuring the system to use CLK_POUT. Unfortunately it is not possible to read the state of SW15 from software so this feature is controlled by a module option 'clk_pout' which should be set to a non-zero value to enable the use of CLK_POUT.

Details for the implementation: It seams that the analog loopback needs the DAC powered on on the channel, where the loopback is selected. The switch for the DACs has been moved from the DAPM_DAC to the "Analog XX Playback Mixer". In this way the DAC will be powered while the audio playback is used or/and the loopback is enabled for the channel. The twl4030 codec powering has been reworked. Now the codec will be powered as long as it does not receives the SND_SOC_BIAS_OFF event. The exceptions are when the given change in the registers needs the codec power down/up cycle in order to take effect. Otherwise the codec is on. When the codec enters to STANDBY state and none of the loopback paths are enabled, than the amplifiers, which are no in the DAPM path are forced to turn off and the PLL is disabled. When playback/capture starts the disabled gains are restored and the PLL is enabled. When one of the loopback enabled in STANDBY mode, the disabled gains are restored and the PLL is enabled also. In short: the codec always goes to the lowest power state based on the bias_level and the bypass_state.

When a codec driver registers with ASoC, a probe function is called. Most codec drivers call ASoC first, and then register with the I2C bus in the ASoC probe function. However, in order to support multiple codecs on one board, it's easier if the codec driver is probed via the I2C bus first. This is because the call to i2c_add_driver() can result in the I2C probe function being called multiple times - once for each codec. In the current design, the driver registers once with ASoC, and in the ASoC probe function, it calls i2c_add_driver(). The results in the I2C probe function being called multiple times before the driver can register with ASoC again. The new design has the driver call i2c_add_driver() first. In the I2C probe function, the driver registers with ASoC. This allows the ASoC probe function to be called once per I2C device. Also add code to check if the I2C probe function is called more than once, since that is not supported with the current ASoC design.

A new function was created so that this pattern could be consolidated. Also, replaced the data[] command vectors and its indexes by meaningful structures as pointed out by Matt Helsley too.

As a result, the white AUX connector can not be used. This rewrites the default config to more accurately reflect the connector layout, colour and function. Unfortunately the black CD_IN connector, which is suspected to be widget 0x1c refuses to switch into input (0x20), instead opting to remain on 0x0. As such, no mixer controls are exposed for it. Autoswitching is implemented between the front headphone output and back line output.

Thus, the probe function requested the wrong SSP port. Correcting this unveiled another bug where ssp_init tries to request the already-requested SSP port again. So this patch replaces the ssp_init/exit calls with their internals from mach-pxa/ssp.c, leaving out the redundant ssp_request and the unneeded IRQ request. Effectively, that leaves us with not much more than enabling/disabling the SSP clock.

As the Trusted Computing (TPM) model requires, IMA measures all files before they are accessed in any way (on the integrity_bprm_check, integrity_path_check and integrity_file_mmap hooks), and commits the measurements to the TPM. Once added to the TPM, measurements can not be removed. In addition, IMA maintains a list of these file measurements, which can be used to validate the aggregate value stored in the TPM. The TPM can sign these measurements, and thus the system can prove, to itself and to a third party, the system's integrity in a way that cannot be circumvented by malicious or compromised software. - alloc ima_template_entry before calling ima_store_template() - log ima_add_boot_aggregate() failure - removed unused IMA_TEMPLATE_NAME_LEN - replaced hard coded string length with #define name Signed-off-by: Mimi Zohar Signed-off-by: James Morris diff --git a/Documentation/kernel-parameters.txt b/Documentation/kernel-parameters.txt index 7c67b94..31e0c2c 100644 --- a/Documentation/kernel-parameters.txt +++ b/Documentation/kernel-parameters.txt @@ -895,6 +895,15 @@ and is between 256 and 4096 characters.

These drivers assumed that the sample size is known in the _prepare function and not in the _hw_params function, but this is not true. Move the code in fsl_dma_prepare() into fsl_dma_hw_param(). Create fsl_ssi_hw_params() and move the code from fsl_ssi_prepare() into it. Turn off snooping for DMA operations to/from I/O registers, since that's not necessary.

TOMOYO Linux performs pathname based access control. To remove factors that make pathname based access control difficult (e.g. symbolic links, "..", "//" etc.), TOMOYO Linux derives realpath of requested pathname from "struct dentry" and "struct vfsmount". The maximum length of string data is limited to 4000 including trailing '\0'. Since TOMOYO Linux uses '\ooo' style representation for non ASCII printable characters, maybe TOMOYO Linux should be able to support 16336 (which means (NAME_MAX * (PATH_MAX / (NAME_MAX + 1)) * 4 + (PATH_MAX / (NAME_MAX + 1))) including trailing '\0'), but I think 4000 is enough for practical use. TOMOYO uses only 0x21 - 0x7E (as printable characters) and 0x20 (as word delimiter) and 0x0A (as line delimiter). 0x01 - 0x20 and 0x80 - 0xFF is handled in \ooo style representation. The reason to use \ooo is to guarantee that "%s" won't damage logs. Userland program can request open("/tmp/file granted.\nAccess /tmp/file ", O_WRONLY | O_CREAT, 0600) and logging such crazy pathname using "Access %s denied.\n" format will cause "fabrication of logs" like Access /tmp/file granted. Access /tmp/file denied. TOMOYO converts such characters to \ooo so that the logs will become Access /tmp/file\040granted.\012Access\040/tmp/file denied. and the administrator can read the logs safely using /bin/cat . Likewise, a crazy request like open("/tmp/\x01\x02\x03\x04\x05\x06\x07\x08\x09", O_WRONLY | O_CREAT, 0600) will be processed safely by converting to Access /tmp/\001\002\003\004\005\006\007\010\011 denied.

This file contains common functions (e.g. policy I/O, pattern matching). -------------------- About pattern matching -------------------- Since TOMOYO Linux is a name based access control, TOMOYO Linux seriously considers "safe" string representation. TOMOYO Linux's string manipulation functions make reviewers feel crazy, but there are reasons why TOMOYO Linux needs its own string manipulation functions. ----- Part 1 : preconditions ----- People definitely want to use wild card. To support pattern matching, we have to support wild card characters. In a typical Linux system, filenames are likely consists of only alphabets, numbers, and some characters (e.g. + - ~ . / ). But theoretically, the Linux kernel accepts all characters but NUL character (which is used as a terminator of a string). Some Linux systems can have filenames which contain * ? ** etc. Therefore, we have to somehow modify string so that we can distinguish wild card characters and normal characters. It might be possible for some application's configuration files to restrict acceptable characters. It is impossible for kernel to restrict acceptable characters. We can't accept approaches which will cause troubles for applications. ----- Part 2 : commonly used approaches ----- Text formatted strings separated by space character (0x20) and new line character (0x0A) is more preferable for users over array of NUL-terminated string. Thus, people use text formatted configuration files separated by space character and new line. We sometimes need to handle non-printable characters. Thus, people use \ character (0x5C) as escape character and represent non-printable characters using octal or hexadecimal format. At this point, we remind (at least) 3 approaches. (1) Shell glob style expression (2) POSIX regular expression (UNIX style regular expression) (3) Maverick wild card expression On the surface, (1) and (2) sound good choices. But they have a big pitfall. All meta-characters in (1) and (2) are legal characters for representing a pathname, and users easily write incorrect expression. What is worse, users unlikely notice incorrect expressions because characters used for regular pathnames unlikely contain meta-characters. This incorrect use of meta-characters in pathname representation reveals vulnerability (e.g. unexpected results) only when irregular pathname is specified. The authors of TOMOYO Linux think that approaches which adds some character for interpreting meta-characters as normal characters (i.e. (1) and (2)) are not suitable for security use. Therefore, the authors of TOMOYO Linux propose (3). ----- Part 3: consideration points ----- We need to solve encoding problem. A single character can be represented in several ways using encodings. For Japanese language, there are "ShiftJIS", "ISO-2022-JP", "EUC-JP", "UTF-8" and more. Some languages (e.g. Japanese language) supports multi-byte characters (where a single character is represented using several bytes). Some multi-byte characters may match the escape character. For Japanese language, some characters in "ShiftJIS" encoding match \ character, and bothering Web's CGI developers. It is important that the kernel string is not bothered by encoding problem. Linus said, "I really would expect that kernel strings don't have an encoding. They're just C strings: a NUL-terminated stream of bytes." http://lkml.org/lkml/2007/11/6/142 Yes. The kernel strings are just C strings. We are talking about how to store and carry "kernel strings" safely. If we store "kernel string" into policy file as-is, the "kernel string" will be interpreted differently depending on application's encoding settings. One application may interpret "kernel string" as "UTF-8", another application may interpret "kernel string" as "ShiftJIS". Therefore, we propose to represent strings using ASCII encoding. In this way, we are no longer bothered by encoding problems. We need to avoid information loss caused by display. It is difficult to input and display non-printable characters, but we have to be able to handle such characters because the kernel string is a C string. If we use only ASCII printable characters (from 0x21 to 0x7E) and space character (0x20) and new line character (0x0A), it is easy to input from keyboard and display on all terminals which is running Linux. Therefore, we propose to represent strings using only characters which value is one of "from 0x21 to 0x7E", "0x20", "0x0A". We need to consider ease of splitting strings from a line. If we use an approach which uses "\ " for representing a space character within a string, we have to count the string from the beginning to check whether this space character is accompanied with \ character or not. As a result, we cannot monotonically split a line using space character. If we use an approach which uses "\040" for representing a space character within a string, we can monotonically split a line using space character. If we use an approach which uses NUL character as a delimiter, we cannot use string manipulation functions for splitting strings from a line. Therefore, we propose that we represent space character as "\040". We need to avoid wrong designations (incorrect use of special characters). Not all users can understand and utilize POSIX's regular expressions correctly and perfectly. If a character acts as a wild card by default, the user will get unexpected result if that user didn't know the meaning of that character. Therefore, we propose that all characters but \ character act as a normal character and let the user add \ character to make a character act as a wild card. In this way, users needn't to know all wild card characters beforehand. They can learn when they encountered an unseen wild card character for their first time. ----- Part 4: supported wild card expressions ----- At this point, we have wild card expressions listed below. +-----------+--------------------------------------------------------------+ | Wild card | Meaning and example | +-----------+--------------------------------------------------------------+ | \* | More than or equals to 0 character other than '/'. | | | /var/log/samba/\* | +-----------+--------------------------------------------------------------+ | \@ | More than or equals to 0 character other than '/' or '.'. | | | /var/www/html/\@.html | +-----------+--------------------------------------------------------------+ | \? | 1 byte character other than '/'. | | | /tmp/mail.\?\?\?\?\?\? | +-----------+--------------------------------------------------------------+ | \$ | More than or equals to 1 decimal digit. | | | /proc/\$/cmdline | +-----------+--------------------------------------------------------------+ | \+ | 1 decimal digit. | | | /var/tmp/my_work.\+ | +-----------+--------------------------------------------------------------+ | \X | More than or equals to 1 hexadecimal digit. | | | /var/tmp/my-work.\X | +-----------+--------------------------------------------------------------+ | \x | 1 hexadecimal digit. | | | /tmp/my-work.\x | +-----------+--------------------------------------------------------------+ | \A | More than or equals to 1 alphabet character. | | | /var/log/my-work/\$-\A-\$.log | +-----------+--------------------------------------------------------------+ | \a | 1 alphabet character. | | | /home/users/\a/\*/public_html/\*.html | +-----------+--------------------------------------------------------------+ | \- | Pathname subtraction operator. | | | +---------------------+------------------------------------+ | | | | Example | Meaning | | | | +---------------------+------------------------------------+ | | | | /etc/\* | All files in /etc/ directory. | | | | +---------------------+------------------------------------+ | | | | /etc/\*\-\*shadow\* | /etc/\* other than /etc/\*shadow\* | | | | +---------------------+------------------------------------+ | | | | /\*\-proc\-sys/ | /\*/ other than /proc/ /sys/ | | | | +---------------------+------------------------------------+ | +-----------+--------------------------------------------------------------+ +----------------+---------------------------------------------------------+ | Representation | Meaning and example | +----------------+---------------------------------------------------------+ | \\ | backslash character itself. | +----------------+---------------------------------------------------------+ | \ooo | 1 byte character. | | | ooo is 001 <= ooo <= 040 || 177 <= ooo <= 377. | | | | | | \040 for space character. | | | \177 for del character. | | | | +----------------+---------------------------------------------------------+ ----- Part 5: Advantages ----- We can obtain extensibility. Since our proposed approach adds \ to a character to interpret as a wild card, we can introduce new wild card in future while maintaining backward compatibility. We can process monotonically. Since our proposed approach separates strings using a space character, we can split strings using existing string manipulation functions. We can reliably analyze access logs. It is guaranteed that a string doesn't contain space character (0x20) and new line character (0x0A). It is guaranteed that a string won't be converted by FTP and won't be damaged by a terminal's settings. It is guaranteed that a string won't be affected by encoding converters (except encodings which insert NUL character (e.g. UTF-16)). ----- Part 6: conclusion ----- TOMOYO Linux is using its own encoding with reasons described above. There is a disadvantage that we need to introduce a series of new string manipulation functions. But TOMOYO Linux's encoding is useful for all users (including audit and AppArmor) who want to perform pattern matching and safely exchange string information between the kernel and the userspace. -------------------- About policy interface -------------------- TOMOYO Linux creates the following files on securityfs (normally mounted on /sys/kernel/security) as interfaces between kernel and userspace. These files are for TOMOYO Linux management tools *only*, not for general programs. * profile * exception_policy * domain_policy * manager * meminfo * self_domain * version * .domain_status * .process_status ** /sys/kernel/security/tomoyo/profile ** This file is used to read or write profiles. "profile" means a running mode of process. A profile lists up functions and their modes in "$number-$variable=$value" format. The $number is profile number between 0 and 255. Each domain is assigned one profile. To assign profile to domains, use "ccs-setprofile" or "ccs-editpolicy" or "ccs-loadpolicy" commands. (Example) [root@tomoyo]# cat /sys/kernel/security/tomoyo/profile 0-COMMENT=-----Disabled Mode----- 0-MAC_FOR_FILE=disabled 0-MAX_ACCEPT_ENTRY=2048 0-TOMOYO_VERBOSE=disabled 1-COMMENT=-----Learning Mode----- 1-MAC_FOR_FILE=learning 1-MAX_ACCEPT_ENTRY=2048 1-TOMOYO_VERBOSE=disabled 2-COMMENT=-----Permissive Mode----- 2-MAC_FOR_FILE=permissive 2-MAX_ACCEPT_ENTRY=2048 2-TOMOYO_VERBOSE=enabled 3-COMMENT=-----Enforcing Mode----- 3-MAC_FOR_FILE=enforcing 3-MAX_ACCEPT_ENTRY=2048 3-TOMOYO_VERBOSE=enabled - MAC_FOR_FILE: Specifies access control level regarding file access requests. - MAX_ACCEPT_ENTRY: Limits the max number of ACL entries that are automatically appended during learning mode. Default is 2048. - TOMOYO_VERBOSE: Specifies whether to print domain policy violation messages or not. ** /sys/kernel/security/tomoyo/manager ** This file is used to read or append the list of programs or domains that can write to /sys/kernel/security/tomoyo interface. By default, only processes with both UID = 0 and EUID = 0 can modify policy via /sys/kernel/security/tomoyo interface. You can use keyword "manage_by_non_root" to allow policy modification by non root user. (Example) [root@tomoyo]# cat /sys/kernel/security/tomoyo/manager /usr/lib/ccs/loadpolicy /usr/lib/ccs/editpolicy /usr/lib/ccs/setlevel /usr/lib/ccs/setprofile /usr/lib/ccs/ld-watch /usr/lib/ccs/ccs-queryd ** /sys/kernel/security/tomoyo/exception_policy ** This file is used to read and write system global settings. Each line has a directive and operand pair. Directives are listed below. - initialize_domain: To initialize domain transition when specific program is executed, use initialize_domain directive. * initialize_domain "program" from "domain" * initialize_domain "program" from "the last program part of domain" * initialize_domain "program" If the part "from" and after is not given, the entry is applied to all domain. If the "domain" doesn't start with "", the entry is applied to all domain whose domainname ends with "the last program part of domain". This directive is intended to aggregate domain transitions for daemon program and program that are invoked by the kernel on demand, by transiting to different domain. - keep_domain To prevent domain transition when program is executed from specific domain, use keep_domain directive. * keep_domain "program" from "domain" * keep_domain "program" from "the last program part of domain" * keep_domain "domain" * keep_domain "the last program part of domain" If the part "from" and before is not given, this entry is applied to all program. If the "domain" doesn't start with "", the entry is applied to all domain whose domainname ends with "the last program part of domain". This directive is intended to reduce total number of domains and memory usage by suppressing unneeded domain transitions. To declare domain keepers, use keep_domain directive followed by domain definition. Any process that belongs to any domain declared with this directive, the process stays at the same domain unless any program registered with initialize_domain directive is executed. In order to control domain transition in detail, you can use no_keep_domain/no_initialize_domain keywrods. - alias: To allow executing programs using the name of symbolic links, use alias keyword followed by dereferenced pathname and reference pathname. For example, /sbin/pidof is a symbolic link to /sbin/killall5 . In normal case, if /sbin/pidof is executed, the domain is defined as if /sbin/killall5 is executed. By specifying "alias /sbin/killall5 /sbin/pidof", you can run /sbin/pidof in the domain for /sbin/pidof . (Example) alias /sbin/killall5 /sbin/pidof - allow_read: To grant unconditionally readable permissions, use allow_read keyword followed by canonicalized file. This keyword is intended to reduce size of domain policy by granting read access to library files such as GLIBC and locale files. Exception is, if ignore_global_allow_read keyword is given to a domain, entries specified by this keyword are ignored. (Example) allow_read /lib/libc-2.5.so - file_pattern: To declare pathname pattern, use file_pattern keyword followed by pathname pattern. The pathname pattern must be a canonicalized Pathname. This keyword is not applicable to neither granting execute permissions nor domain definitions. For example, canonicalized pathname that contains a process ID (i.e. /proc/PID/ files) needs to be grouped in order to make access control work well. (Example) file_pattern /proc/\$/cmdline - path_group To declare pathname group, use path_group keyword followed by name of the group and pathname pattern. For example, if you want to group all files under home directory, you can define path_group HOME-DIR-FILE /home/\*/\* path_group HOME-DIR-FILE /home/\*/\*/\* path_group HOME-DIR-FILE /home/\*/\*/\*/\* in the exception policy and use like allow_read @HOME-DIR-FILE to grant file access permission. - deny_rewrite: To deny overwriting already written contents of file (such as log files) by default, use deny_rewrite keyword followed by pathname pattern. Files whose pathname match the patterns are not permitted to open for writing without append mode or truncate unless the pathnames are explicitly granted using allow_rewrite keyword in domain policy. (Example) deny_rewrite /var/log/\* - aggregator To deal multiple programs as a single program, use aggregator keyword followed by name of original program and aggregated program. This keyword is intended to aggregate similar programs. For example, /usr/bin/tac and /bin/cat are similar. By specifying "aggregator /usr/bin/tac /bin/cat", you can run /usr/bin/tac in the domain for /bin/cat . For example, /usr/sbin/logrotate for Fedora Core 3 generates programs like /tmp/logrotate.\?\?\?\?\?\? and run them, but TOMOYO Linux doesn't allow using patterns for granting execute permission and defining domains. By specifying "aggregator /tmp/logrotate.\?\?\?\?\?\? /tmp/logrotate.tmp", you can run /tmp/logrotate.\?\?\?\?\?\? as if /tmp/logrotate.tmp is running. ** /sys/kernel/security/tomoyo/domain_policy ** This file contains definition of all domains and permissions that are granted to each domain. Lines from the next line to a domain definition ( any lines starting with "") to the previous line to the next domain definitions are interpreted as access permissions for that domain. ** /sys/kernel/security/tomoyo/meminfo ** This file is to show the total RAM used to keep policy in the kernel by TOMOYO Linux in bytes. (Example) [root@tomoyo]# cat /sys/kernel/security/tomoyo/meminfo Shared: 61440 Private: 69632 Dynamic: 768 Total: 131840 You can set memory quota by writing to this file. (Example) [root@tomoyo]# echo Shared: 2097152 > /sys/kernel/security/tomoyo/meminfo [root@tomoyo]# echo Private: 2097152 > /sys/kernel/security/tomoyo/meminfo ** /sys/kernel/security/tomoyo/self_domain ** This file is to show the name of domain the caller process belongs to. (Example) [root@etch]# cat /sys/kernel/security/tomoyo/self_domain /usr/sbin/sshd /bin/zsh /bin/cat ** /sys/kernel/security/tomoyo/version ** This file is used for getting TOMOYO Linux's version. (Example) [root@etch]# cat /sys/kernel/security/tomoyo/version 2.2.0-pre ** /sys/kernel/security/tomoyo/.domain_status ** This is a view (of a DBMS) that contains only profile number and domainnames of domain so that "ccs-setprofile" command can do line-oriented processing easily. ** /sys/kernel/security/tomoyo/.process_status ** This file is used by "ccs-ccstree" command to show "list of processes currently running" and "domains which each process belongs to" and "profile number which the domain is currently assigned" like "pstree" command. This file is writable by programs that aren't registered as policy manager.

This file controls file related operations of TOMOYO Linux. tomoyo/tomoyo.c calls the following six functions in this file. Each function handles the following access types. * tomoyo_check_file_perm sysctl()'s "read" and "write". * tomoyo_check_exec_perm "execute". * tomoyo_check_open_permission open(2) for "read" and "write". * tomoyo_check_1path_perm "create", "unlink", "mkdir", "rmdir", "mkfifo", "mksock", "mkblock", "mkchar", "truncate" and "symlink". * tomoyo_check_2path_perm "rename" and "unlink". * tomoyo_check_rewrite_permission "rewrite". ("rewrite" are operations which may lose already recorded data of a file, i.e. open(!O_APPEND) || open(O_TRUNC) || truncate() || ftruncate()) The functions which actually checks ACLs are the following three functions. Each function handles the following access types. ACL directive is expressed by "allow_". * tomoyo_check_file_acl Open() operation and execve() operation. ("read", "write", "read/write" and "execute") * tomoyo_check_single_write_acl Directory modification operations with 1 pathname. ("create", "unlink", "mkdir", "rmdir", "mkfifo", "mksock", "mkblock", "mkchar", "truncate", "symlink" and "rewrite") * tomoyo_check_double_write_acl Directory modification operations with 2 pathname. ("link" and "rename") Also, this file contains handlers of some utility directives for file related operations. * "allow_read": specifies globally (for all domains) readable files. * "path_group": specifies pathname macro. * "deny_rewrite": restricts rewrite operation.

This file controls domain creation/deletion/transition. Every process belongs to a domain in TOMOYO Linux. Domain transition occurs when execve(2) is called and the domain is expressed as 'process invocation history', such as ' /sbin/init /etc/init.d/rc'. Domain information is stored in current->cred->security field.

Let's consider 3 patterns (statically linked, dynamically linked, shell script). This description is to some degree simplified. $ cat hello.c #include int main() { printf("Hello\n"); return 0; } $ cat hello.sh #! /bin/sh echo "Hello" $ gcc -static -o hello-static hello.c $ gcc -o hello-dynamic hello.c $ chmod 755 hello.sh Case 1 -- Executing hello-static from bash. (1) The bash process calls fork() and the child process requests do_execve("hello-static"). (2) The kernel checks "allow_execute hello-static" from "bash" domain. (3) The kernel calculates "bash hello-static" as the domain to transit to. (4) The kernel overwrites the child process by "hello-static". (5) The child process transits to "bash hello-static" domain. (6) The "hello-static" starts and finishes. Case 2 -- Executing hello-dynamic from bash. (1) The bash process calls fork() and the child process requests do_execve("hello-dynamic"). (2) The kernel checks "allow_execute hello-dynamic" from "bash" domain. (3) The kernel calculates "bash hello-dynamic" as the domain to transit to. (4) The kernel checks "allow_read ld-linux.so" from "bash hello-dynamic" domain. I think permission to access ld-linux.so should be charged hello-dynamic program, for "hello-dynamic needs ld-linux.so" is not a fault of bash program. (5) The kernel overwrites the child process by "hello-dynamic". (6) The child process transits to "bash hello-dynamic" domain. (7) The "hello-dynamic" starts and finishes. Case 3 -- Executing hello.sh from bash. (1) The bash process calls fork() and the child process requests do_execve("hello.sh"). (2) The kernel checks "allow_execute hello.sh" from "bash" domain. (3) The kernel calculates "bash hello.sh" as the domain to transit to. (4) The kernel checks "allow_read /bin/sh" from "bash hello.sh" domain. I think permission to access /bin/sh should be charged hello.sh program, for "hello.sh needs /bin/sh" is not a fault of bash program. (5) The kernel overwrites the child process by "/bin/sh". (6) The child process transits to "bash hello.sh" domain. (7) The "/bin/sh" requests open("hello.sh"). (8) The kernel checks "allow_read hello.sh" from "bash hello.sh" domain. (9) The "/bin/sh" starts and finishes. Whether a file is interpreted as a program or not depends on an application. The kernel cannot know whether the file is interpreted as a program or not. Thus, TOMOYO treats "hello-static" "hello-dynamic" "ld-linux.so" "hello.sh" "/bin/sh" equally as merely files; no distinction between executable and non-executable. Therefore, TOMOYO doesn't check DAC's execute permission. TOMOYO checks "allow_read" permission instead. Calling do_execve() is a bold gesture that an old program's instance (i.e. current process) is ready to be overwritten by a new program and is ready to transfer control to the new program. To split purview of programs, TOMOYO requires "allow_execute" permission of the new program against the old program's instance and performs domain transition. If do_execve() succeeds, the old program is no longer responsible against the consequence of the new program's behavior. Only the new program is responsible for all consequences. But TOMOYO doesn't require "allow_read" permission of the new program. If TOMOYO requires "allow_read" permission of the new program, TOMOYO will allow an attacker (who hijacked the old program's instance) to open the new program and steal data from the new program. Requiring "allow_read" permission will widen purview of the old program. Not requiring "allow_read" permission of the new program against the old program's instance is my design for reducing purview of the old program. To be able to know whether the current process is in do_execve() or not, I want to add in_execve flag to "task_struct".

Soft Ramp, Zero Cross, and Auto-Mute are disabled by the driver when it first initializes the hardware, but these features either don't work or interfere with normal ALSA behavior. However, they can now be re-enabled by an application if desired. Remove CONFIG_SND_SOC_CS4270_HWMUTE and always allow ASoC to control the mute bits. The driver previously and erroneously assumed that these bits control only external muting circuitry, but they also control internal muting circuitry, so they should always be used.

This patch converts the avc cache to use hlists in which there is a single pointer from the head which saves us about 4k of global memory. Resulted in about a 1.5% decrease in time spent in avc_has_perm_noaudit based on oprofile sampling of tbench. Although likely within the noise....

These instructions enable fast and secure data encryption and decryption, using the Advanced Encryption Standard (AES), defined by FIPS Publication number 197. The architecture introduces six instructions that offer full hardware support for AES. Four of them support high performance data encryption and decryption, and the other two instructions support the AES key expansion procedure. The white paper can be downloaded from: http://softwarecommunity.intel.com/isn/downloads/intelavx/AES-Instructions-Set_WP.pdf AES may be used in soft_irq context, but MMX/SSE context can not be touched safely in soft_irq context. So in_interrupt() is checked, if in IRQ or soft_irq context, the general x86_64 implementation are used instead.

While its nice to have default known values for testing purposes, it seems dangerous to allow the use of those default values without some sort of safety measure in place, lest an attacker easily guess the output of the cprng. This patch forces the NEED_RESET flag on when allocating a cprng context, so that any user is forced to reseed it before use. The defaults can still be used for testing, but this will prevent their inadvertent use, and be more secure.

We already panic when any of the test in testmgr.c fail when we are operating in fips mode. The continuous test in the cprng here was missed when that was implmented. This code simply checks for the fips_enabled flag if the test fails, and warns us via syslog or panics the box accordingly.

However, we need exactly that when constructing givcipher and aead so this patch adds support for that by setting the tested bit in type but clearing it in mask. This combination is currently unused.

The functions crypto_alloc_tfm and create_create_tfm return a pointer that needs to be adjusted by the caller when successful and otherwise an error value. This means that the caller has to check for the error and only perform the adjustment if the pointer returned is valid. Since all callers want to make the adjustment and we know how to adjust it ourselves, it's much easier to just return adjusted pointer directly. The only caveat is that we have to return a void * instead of struct crypto_tfm *. However, this isn't that bad because both of these functions are for internal use only (by types code like shash.c, not even algorithms code). This patch also moves crypto_alloc_tfm into crypto/internal.h (crypto_create_tfm is already there) to reflect this.

This patch fixes the bypass logic to test these algorithms. Conversely, we're currently testing nivaead algorithms with IVs, which would have deadlocked had it not been for the fact that no nivaead algorithms have any test vectors. This patch also fixes that case. Both fixes are ugly as hell, but this ugliness should hopefully disappear once we move them into the per-type code (i.e., the AEAD test would live in aead.c and the skcipher stuff in ablkcipher.c).

In struct cryptd_cpu_queue, a struct crypto_queue holds all requests for the CPU, a struct work_struct is used to run all requests for the CPU.

This patch updates the maple bus to support asynchronous block reads and writes as well as generally improving the quality of the code and supporting concurrency (all needed to support the Dreamcast visual memory unit - a driver will also be posted for that). Changes in the bus driver necessitate some changes in the two maple bus input drivers that are currently in mainline. As well as supporting block reads and writes this code clean up removes some poor handling of locks, uses an atomic status variable to serialise access to devices and more robusly handles the general performance problems of the bus.

This helps processors such as sh7750, sh7780 and sh7785 which have more vectors than masking ability. With this patch in place we can modify the intc tables to use one irq per maskable irq source. Please note the following: - If multiple vectors share the same enum then only the first vector will be available as a linux irq. - Drivers may need to be rewritten to get pending irq source from the hardware block instead of irq number. This patch together with the sh7785 specific intc tables solves DMA controller irq issues related to buggy interrupt masking.

More specifically, they add/remove the uart_{rts,cts}_pin fields in bfin_serial_resources based on whether the particular port has rts/cts enabled, as opposed to when either port has it enabled. This patch fixed this.

In several use-cases (e.g. compressed file systems that store files in big compressed blocks), this workflow is not suitable. Furthermore, the "comp" type doesn't provide for the configuration of (de)compression parameters, and always allocates workspace memory for both compression and decompression, which may waste memory. To solve this, add a "pcomp" partial (de)compression interface that provides the following operations: - crypto_compress_{init,update,final}() for compression, - crypto_decompress_{init,update,final}() for decompression, - crypto_{,de}compress_setup(), to configure (de)compression parameters (incl. allocating workspace memory). The (de)compression methods take a struct comp_request, which was mimicked after the z_stream object in zlib, and contains buffer pointer and length pairs for input and output. The setup methods take an opaque parameter pointer and length pair. Parameters are supposed to be encoded using netlink attributes, whose meanings depend on the actual (name of the) (de)compression algorithm.

The gpio support exports two new functions: snd_soc_jack_add_gpios and snd_soc_jack_free_gpios. Client drivers using gpio feature must pass an array of jack_gpio pins belonging to a specific jack to the snd_soc_jack_add_gpios function. The framework will request the gpios, set the data direction and request irq. The framework will update power status of related jack_pins when an event on the gpio pins comes according to the reporting bits defined for each gpio. All gpio resources allocated when adding jack_gpio pins can be released using snd_soc_jack_free_gpios function.

If we use PTRACE_GETFPREGS on another process and both processes did not already use floating point, we get a null pointer exception in finit. This patch creates a new function finit_task that takes a task_struct parameter. finit becomes a wrapper that simply calls finit_task with current. On the plus side this avoids many calls to get_current which would each resolve to an inline assembler mov instruction. An empty finit_task has been added to i387.h to avoid linker errors in case the compiler still emits the call in init_fpu when CONFIG_MATH_EMULATION is not defined. The declaration of finit in i387.h has been removed as the remaining code using this function gets its prototype from fpu_proto.h.

Miller" Date: Wed, 4 Mar 2009 14:43:47 -0800 Subject: sparc64: Fix lost interrupts on sun4u. Based upon a report by Meelis Roos. Sparc64 SBUS and PCI controllers use a combination of IMAP and ICLR registers to manage device interrupts. The IMAP register contains the "valid" enable bit as well as CPU targetting information. Whereas the ICLR register is written with zero at the end of handling an interrupt to reset the state machine for that interrupt to IDLE so it can be sent again. For PCI slot and SBUS slot devices we can have multiple interrupts sharing the same IMAP register. There are individual ICLR registers but only one IMAP register for managing those. We represent each shared case with individual virtual IRQs so the generic IRQ layer thinks there is only one user of the IRQ instance. In such shared IMAP cases this is wrong, so if there are multiple active users then a free_irq() call will prematurely turn off the interrupt by clearing the Valid bit in the IMAP register even though there are other active users. Fix this by simply doing nothing in sun4u_disable_irq() and checking IRQF_DISABLED during IRQ dispatch. This situation doesn't exist in the hypervisor sun4v cases, so I left those alone.

I believe that this is because ext4_free_inode() uses atomic bitops, and although ext4_new_inode() *used* to also use atomic bitops for synchronization, commit 393418676a7602e1d7d3f6e560159c65c8cbd50e changed this to use the sb_bgl_lock, so that we could also synchronize against read_inode_bitmap and initialization of uninit inode tables. However, that change left ext4_free_inode using atomic bitops, which I think leaves no synchronization between setting & unsetting bits in the inode table. The below patch fixes it for me, although I wonder if we're getting at all heavy-handed with this spinlock...

The ATA-6 spec appears to allow 5 seconds for a drive to be ready. On one affected system, this patch changes "PM: resume devices took..." message from 17 seconds to 4 seconds, and gets rid of a lot of ugly timeout/error messages. Without this patch, the libata code moves on after 1s, tries to send a soft reset (which the drive doesn't see because it isn't ready) which also times out, then an IDENTIFY command is sent to the drive which times out, and finally the error handler will try to send another hard reset which will finally get things working.

However, the skip path forgot to thaw the port, which not only blocks further event notification from the port but also causes repeated EH invocations on the same event on drivers which rely on ->thaw() to clear events if the IRQ is shared with another device or port. This problem has always been there but is uncovered by recent sata_nv nf2/3 change which dropped hardreset support while maintaining SCR access. nf2/3 doesn't clear hotplug event mask from the interrupt handler but relies on ->thaw() to clear them. When the hardreset was there, the reset action was never skipped and the port was always thawed but, with the hardreset gone, ->prereset() determines that there's no need for softreset and both ->softreset() and ->thaw() are skipped. This leads to stuck hotplug event in the IRQ status register triggering hotplug event whenever IRQ is delieverd on the same IRQ. As the controller shares the same IRQ for both ports, this happens on every IO if one port is occpupied and the other isn't. This patch fixes the problem by making sure that the port is thawed on reset-skip path. bko#11615 reports this problem.

Unfortunately it seems older ATA specs were vague about what this field should contain and a number of drives used values with wrong byte order or that were totally bogus.

The tick rate define (ORION5X_TCLK) was removed in favor of a runtime detection. The quick fix is to add the define in the watchdog driver. The fix is not correct for all supported orion5x platforms, but since the supported platforms right now are 133 Mhz and 166 Mhz, it won't be _that_ far off. ;-) A fix that uses the runtime-determined timer tick rate will be applied later.

Asynchronous mode allows playback and capture to use different sample sizes. It also technically allows different sample rates, but the driver does not support that.

The fcoe_xmit was getting called with bh disabled, thus causing "BUG: scheduling while atomic" when grabbing lport->lp_muex with bh disabled. 2. fc_linkup and fc_linkdown function calls lport_enter function with lport->lp_mutex held and these enter function in turn calls fcoe_xmit to send lport related FC frame, e.g. fc_linkup => fc_lport_enter_flogi to send flogi req. In this case grabbing the same lport->lp_mutex again in fc_puase from fcoe_xmit would cause deadlock. The lport->lp_mutex was used for setting FC_PAUSE in fcoe_xmit path but FC_PAUSE bit was not used anywhere beside just setting and clear this bit in lport->link_status, instead used a separate field qfull in fc_lport to eliminate need for lport->lp_mutex to track pending queue full condition and in turn avoid above described two locking issues. Also added check for lp->qfull in fc_fcp_lport_queue_ready to trigger SCSI_MLQUEUE_HOST_BUSY when lp->qfull is set to prevent more scsi-ml cmds while lp->qfull is set. This patch eliminated FC_LINK_UP and FC_PAUSE and instead used dedicated fields in fc_lport for this, this simplified all related conditional code. Also removed fc_pause and fc_unpause functions and instead used newly added lport->qfull directly in fcoe.

The rport error handling would only retry on resource allocation failures and exchange timeouts. I have a target that will occasionally reject PLOGI when we do a quick LOGO/PLOGI. When a critical ELS was rejected, libfc would fail silently leaving the rport in a dead state. The retry count and delay are managed by fc_rport_error_retry. If the retry count is exceeded fc_rport_error will be called. When retrying is not the correct course of action, fc_rport_error can be called directly.

Thus if fc_exch_alloc() is called when retrying the sequence, the mempool_alloc() will fail to allocate the exchange because the mempool of the exchange manager has already been released. This patch is to cancel any pending retry work of the local port before we start to destroy the interface. Also, when resetting the local port, we should also stop the scheduled pending retries.

If we destroy the interface, we'll go through each rport on the disc->rports list and set each rport's state to NONE. Then the lport will reset the EM. The EM reset will send a CLOSED event to the prli_resp() handler which will notice that the state != PRLI. In this case it frees the frame pointer, decrements the refcount and unlocks the rport. The problem is that there isn't a frame in this case. It's just a pointer with an embedded error code. The free causes an Oops. This patch moves the error checking to be before the state checking.

After a second grace period the pages get into rcu_free_kmmio_fault_pages() and raise a BUG_ON() kernel crash. The list manipulation is fixed to properly remove pages from the release list.

Tested by Stuart (on 32-bit) and Pekka (on amd and intel 64-bit systems, nouveau and nvidia proprietary).

The values of normal slave elements are supposed to be cachable, i.e. they are changed only via the put callbacks. OTOH, when a slave element is volatile and its values may be changed by other reason (e.g. hardware status change), the values will get inconsistent. The new function allows the slave elements with volatile changes. When the slave is tied with this call, the native get callback is issued at each time so that the values are always updated.

The document focuses mainly on PCI soundcards. + In the case of other device types, the API might + be different, too. However, at least the ALSA kernel API is + consistent, and therefore it would be still a bit help for + writing them. + + + + This document targets people who already have enough + C language skills and have basic linux kernel programming + knowledge. This document doesn't explain the general + topic of linux kernel coding and doesn't cover low-level + driver implementation details. It only describes + the standard way to write a PCI sound driver on ALSA. + + + + If you are already familiar with the older ALSA ver.0.5.x API, you + can check the drivers such as sound/pci/es1938.c or + sound/pci/maestro3.c which have also almost the same + code-base in the ALSA 0.5.x tree, so you can compare the differences. + + + + This document is still a draft version. Any feedback and + corrections, please!! + + + + + + + + + File Tree Structure + +
+ General + + The ALSA drivers are provided in two ways. + + + + One is the trees provided as a tarball or via cvs from the + ALSA's ftp site, and another is the 2.6 (or later) Linux kernel + tree. To synchronize both, the ALSA driver tree is split into + two different trees: alsa-kernel and alsa-driver. The former + contains purely the source code for the Linux 2.6 (or later) + tree. This tree is designed only for compilation on 2.6 or + later environment. The latter, alsa-driver, contains many subtle + files for compiling ALSA drivers outside of the Linux kernel tree, + wrapper functions for older 2.2 and 2.4 kernels, to adapt the latest kernel API, + and additional drivers which are still in development or in + tests. The drivers in alsa-driver tree will be moved to + alsa-kernel (and eventually to the 2.6 kernel tree) when they are + finished and confirmed to work fine. + + + + The file tree structure of ALSA driver is depicted below. Both + alsa-kernel and alsa-driver have almost the same file + structure, except for core directory. It's + named as acore in alsa-driver tree. + + + ALSA File Tree Structure + + sound + /core + /oss + /seq + /oss + /instr + /ioctl32 + /include + /drivers + /mpu401 + /opl3 + /i2c + /l3 + /synth + /emux + /pci + /(cards) + /isa + /(cards) + /arm + /ppc + /sparc + /usb + /pcmcia /(cards) + /oss + + + +
+ +
+ core directory + + This directory contains the middle layer which is the heart + of ALSA drivers. In this directory, the native ALSA modules are + stored. The sub-directories contain different modules and are + dependent upon the kernel config. + + +
+ core/oss + + + The codes for PCM and mixer OSS emulation modules are stored + in this directory. The rawmidi OSS emulation is included in + the ALSA rawmidi code since it's quite small. The sequencer + code is stored in core/seq/oss directory (see + + below). + +
+ +
+ core/ioctl32 + + + This directory contains the 32bit-ioctl wrappers for 64bit + architectures such like x86-64, ppc64 and sparc64. For 32bit + and alpha architectures, these are not compiled. + +
+ +
+ core/seq + + This directory and its sub-directories are for the ALSA + sequencer. This directory contains the sequencer core and + primary sequencer modules such like snd-seq-midi, + snd-seq-virmidi, etc. They are compiled only when + CONFIG_SND_SEQUENCER is set in the kernel + config. + +
+ +
+ core/seq/oss + + This contains the OSS sequencer emulation codes. + +
+ +
+ core/seq/instr + + This directory contains the modules for the sequencer + instrument layer. + +
+
+ +
+ include directory + + This is the place for the public header files of ALSA drivers, + which are to be exported to user-space, or included by + several files at different directories. Basically, the private + header files should not be placed in this directory, but you may + still find files there, due to historical reasons :) + +
+ +
+ drivers directory + + This directory contains code shared among different drivers + on different architectures. They are hence supposed not to be + architecture-specific. + For example, the dummy pcm driver and the serial MIDI + driver are found in this directory. In the sub-directories, + there is code for components which are independent from + bus and cpu architectures. + + +
+ drivers/mpu401 + + The MPU401 and MPU401-UART modules are stored here. + +
+ +
+ drivers/opl3 and opl4 + + The OPL3 and OPL4 FM-synth stuff is found here. + +
+
+ +
+ i2c directory + + This contains the ALSA i2c components. + + + + Although there is a standard i2c layer on Linux, ALSA has its + own i2c code for some cards, because the soundcard needs only a + simple operation and the standard i2c API is too complicated for + such a purpose. + + +
+ i2c/l3 + + This is a sub-directory for ARM L3 i2c. + +
+
+ +
+ synth directory + + This contains the synth middle-level modules. + + + + So far, there is only Emu8000/Emu10k1 synth driver under + the synth/emux sub-directory. + +
+ +
+ pci directory + + This directory and its sub-directories hold the top-level card modules + for PCI soundcards and the code specific to the PCI BUS. + + + + The drivers compiled from a single file are stored directly + in the pci directory, while the drivers with several source files are + stored on their own sub-directory (e.g. emu10k1, ice1712). + +
+ +
+ isa directory + + This directory and its sub-directories hold the top-level card modules + for ISA soundcards. + +
+ +
+ arm, ppc, and sparc directories + + They are used for top-level card modules which are + specific to one of these architectures. + +
+ +
+ usb directory + + This directory contains the USB-audio driver. In the latest version, the + USB MIDI driver is integrated in the usb-audio driver. + +
+ +
+ pcmcia directory + + The PCMCIA, especially PCCard drivers will go here. CardBus + drivers will be in the pci directory, because their API is identical + to that of standard PCI cards. + +
+ +
+ oss directory + + The OSS/Lite source files are stored here in Linux 2.6 (or + later) tree. In the ALSA driver tarball, this directory is empty, + of course :) + +
+ + + + + + + + Basic Flow for PCI Drivers + +
+ Outline + + The minimum flow for PCI soundcards is as follows: + + + define the PCI ID table (see the section + PCI Entries + ). + create probe() callback. + create remove() callback. + create a pci_driver structure + containing the three pointers above. + create an init() function just calling + the pci_register_driver() to register the pci_driver table + defined above. + create an exit() function to call + the pci_unregister_driver() function. + + +
+ +
+ Full Code Example + + The code example is shown below. Some parts are kept + unimplemented at this moment but will be filled in the + next sections. The numbers in the comment lines of the + snd_mychip_probe() function + refer to details explained in the following section. + + + Basic Flow for PCI Drivers - Example + + + #include + #include + #include + #include + + /* module parameters (see "Module Parameters") */ + /* SNDRV_CARDS: maximum number of cards supported by this module */ + static int index[SNDRV_CARDS] = SNDRV_DEFAULT_IDX; + static char *id[SNDRV_CARDS] = SNDRV_DEFAULT_STR; + static int enable[SNDRV_CARDS] = SNDRV_DEFAULT_ENABLE_PNP; + + /* definition of the chip-specific record */ + struct mychip { + struct snd_card *card; + /* the rest of the implementation will be in section + * "PCI Resource Management" + */ + }; + + /* chip-specific destructor + * (see "PCI Resource Management") + */ + static int snd_mychip_free(struct mychip *chip) + { + .... /* will be implemented later... */ + } + + /* component-destructor + * (see "Management of Cards and Components") + */ + static int snd_mychip_dev_free(struct snd_device *device) + { + return snd_mychip_free(device->device_data); + } + + /* chip-specific constructor + * (see "Management of Cards and Components") + */ + static int __devinit snd_mychip_create(struct snd_card *card, + struct pci_dev *pci, + struct mychip **rchip) + { + struct mychip *chip; + int err; + static struct snd_device_ops ops = { + .dev_free = snd_mychip_dev_free, + }; + + *rchip = NULL; + + /* check PCI availability here + * (see "PCI Resource Management") + */ + .... + + /* allocate a chip-specific data with zero filled */ + chip = kzalloc(sizeof(*chip), GFP_KERNEL); + if (chip == NULL) + return -ENOMEM; + + chip->card = card; + + /* rest of initialization here; will be implemented + * later, see "PCI Resource Management" + */ + .... + + err = snd_device_new(card, SNDRV_DEV_LOWLEVEL, chip, &ops); + if (err < 0) { + snd_mychip_free(chip); + return err; + } + + snd_card_set_dev(card, &pci->dev); + + *rchip = chip; + return 0; + } + + /* constructor -- see "Constructor" sub-section */ + static int __devinit snd_mychip_probe(struct pci_dev *pci, + const struct pci_device_id *pci_id) + { + static int dev; + struct snd_card *card; + struct mychip *chip; + int err; + + /* (1) */ + if (dev >= SNDRV_CARDS) + return -ENODEV; + if (!enable[dev]) { + dev++; + return -ENOENT; + } + + /* (2) */ + err = snd_card_create(index[dev], id[dev], THIS_MODULE, 0, &card); + if (err < 0) + return err; + + /* (3) */ + err = snd_mychip_create(card, pci, &chip); + if (err < 0) { + snd_card_free(card); + return err; + } + + /* (4) */ + strcpy(card->driver, "My Chip"); + strcpy(card->shortname, "My Own Chip 123"); + sprintf(card->longname, "%s at 0x%lx irq %i", + card->shortname, chip->ioport, chip->irq); + + /* (5) */ + .... /* implemented later */ + + /* (6) */ + err = snd_card_register(card); + if (err < 0) { + snd_card_free(card); + return err; + } + + /* (7) */ + pci_set_drvdata(pci, card); + dev++; + return 0; + } + + /* destructor -- see the "Destructor" sub-section */ + static void __devexit snd_mychip_remove(struct pci_dev *pci) + { + snd_card_free(pci_get_drvdata(pci)); + pci_set_drvdata(pci, NULL); + } +]]> + + + +
+ +
+ Constructor + + The real constructor of PCI drivers is the probe callback. + The probe callback and other component-constructors which are called + from the probe callback should be defined with + the __devinit prefix. You + cannot use the __init prefix for them, + because any PCI device could be a hotplug device. + + + + In the probe callback, the following scheme is often used. + + +
+ 1) Check and increment the device index. + + + += SNDRV_CARDS) + return -ENODEV; + if (!enable[dev]) { + dev++; + return -ENOENT; + } +]]> + + + + where enable[dev] is the module option. + + + + Each time the probe callback is called, check the + availability of the device. If not available, simply increment + the device index and returns. dev will be incremented also + later (step + 7). + +
+ +
+ 2) Create a card instance + + + + + + + + + + The details will be explained in the section + + Management of Cards and Components. + +
+ +
+ 3) Create a main component + + In this part, the PCI resources are allocated. + + + + + + + + The details will be explained in the section PCI Resource + Management. + +
+ +
+ 4) Set the driver ID and name strings. + + + +driver, "My Chip"); + strcpy(card->shortname, "My Own Chip 123"); + sprintf(card->longname, "%s at 0x%lx irq %i", + card->shortname, chip->ioport, chip->irq); +]]> + + + + The driver field holds the minimal ID string of the + chip. This is used by alsa-lib's configurator, so keep it + simple but unique. + Even the same driver can have different driver IDs to + distinguish the functionality of each chip type. + + + + The shortname field is a string shown as more verbose + name. The longname field contains the information + shown in /proc/asound/cards. + +
+ +
+ 5) Create other components, such as mixer, MIDI, etc. + + Here you define the basic components such as + PCM, + mixer (e.g. AC97), + MIDI (e.g. MPU-401), + and other interfaces. + Also, if you want a proc + file, define it here, too. + +
+ +
+ 6) Register the card instance. + + + + + + + + + + Will be explained in the section Management + of Cards and Components, too. + +
+ +
+ 7) Set the PCI driver data and return zero. + + + + + + + + In the above, the card record is stored. This pointer is + used in the remove callback and power-management + callbacks, too. + +
+
+ +
+ Destructor + + The destructor, remove callback, simply releases the card + instance. Then the ALSA middle layer will release all the + attached components automatically. + + + + It would be typically like the following: + + + + + + + + The above code assumes that the card pointer is set to the PCI + driver data. + +
+ +
+ Header Files + + For the above example, at least the following include files + are necessary. + + + + + #include + #include + #include + #include +]]> + + + + where the last one is necessary only when module options are + defined in the source file. If the code is split into several + files, the files without module options don't need them. + + + + In addition to these headers, you'll need + <linux/interrupt.h> for interrupt + handling, and <asm/io.h> for I/O + access. If you use the mdelay() or + udelay() functions, you'll need to include + <linux/delay.h> too. + + + + The ALSA interfaces like the PCM and control APIs are defined in other + <sound/xxx.h> header files. + They have to be included after + <sound/core.h>. + + +
+ + + + + + + + Management of Cards and Components + +
+ Card Instance + + For each soundcard, a card record must be allocated. + + + + A card record is the headquarters of the soundcard. It manages + the whole list of devices (components) on the soundcard, such as + PCM, mixers, MIDI, synthesizer, and so on. Also, the card + record holds the ID and the name strings of the card, manages + the root of proc files, and controls the power-management states + and hotplug disconnections. The component list on the card + record is used to manage the correct release of resources at + destruction. + + + + As mentioned above, to create a card instance, call + snd_card_create(). + + + + + + + + + + The function takes five arguments, the card-index number, the + id string, the module pointer (usually + THIS_MODULE), + the size of extra-data space, and the pointer to return the + card instance. The extra_size argument is used to + allocate card->private_data for the + chip-specific data. Note that these data + are allocated by snd_card_create(). + +
+ +
+ Components + + After the card is created, you can attach the components + (devices) to the card instance. In an ALSA driver, a component is + represented as a struct snd_device object. + A component can be a PCM instance, a control interface, a raw + MIDI interface, etc. Each such instance has one component + entry. + + + + A component can be created via + snd_device_new() function. + + + + + + + + + + This takes the card pointer, the device-level + (SNDRV_DEV_XXX), the data pointer, and the + callback pointers (&ops). The + device-level defines the type of components and the order of + registration and de-registration. For most components, the + device-level is already defined. For a user-defined component, + you can use SNDRV_DEV_LOWLEVEL. + + + + This function itself doesn't allocate the data space. The data + must be allocated manually beforehand, and its pointer is passed + as the argument. This pointer is used as the + (chip identifier in the above example) + for the instance. + + + + Each pre-defined ALSA component such as ac97 and pcm calls + snd_device_new() inside its + constructor. The destructor for each component is defined in the + callback pointers. Hence, you don't need to take care of + calling a destructor for such a component. + + + + If you wish to create your own component, you need to + set the destructor function to the dev_free callback in + the ops, so that it can be released + automatically via snd_card_free(). + The next example will show an implementation of chip-specific + data. + +
+ +
+ Chip-Specific Data + + Chip-specific information, e.g. the I/O port address, its + resource pointer, or the irq number, is stored in the + chip-specific record. + + + + + + + + + + In general, there are two ways of allocating the chip record. + + +
+ 1. Allocating via <function>snd_card_create()</function>. + + As mentioned above, you can pass the extra-data-length + to the 4th argument of snd_card_create(), i.e. + + + + + + + + struct mychip is the type of the chip record. + + + + In return, the allocated record can be accessed as + + + +private_data; +]]> + + + + With this method, you don't have to allocate twice. + The record is released together with the card instance. + +
+ +
+ 2. Allocating an extra device. + + + After allocating a card instance via + snd_card_create() (with + 0 on the 4th arg), call + kzalloc(). + + + + + + + + + + The chip record should have the field to hold the card + pointer at least, + + + + + + + + + + Then, set the card pointer in the returned chip instance. + + + +card = card; +]]> + + + + + + Next, initialize the fields, and register this chip + record as a low-level device with a specified + ops, + + + + + + + + snd_mychip_dev_free() is the + device-destructor function, which will call the real + destructor. + + + + + +device_data); + } +]]> + + + + where snd_mychip_free() is the real destructor. + +
+
+ +
+ Registration and Release + + After all components are assigned, register the card instance + by calling snd_card_register(). Access + to the device files is enabled at this point. That is, before + snd_card_register() is called, the + components are safely inaccessible from external side. If this + call fails, exit the probe function after releasing the card via + snd_card_free(). + + + + For releasing the card instance, you can call simply + snd_card_free(). As mentioned earlier, all + components are released automatically by this call. + + + + As further notes, the destructors (both + snd_mychip_dev_free and + snd_mychip_free) cannot be defined with + the __devexit prefix, because they may be + called from the constructor, too, at the false path. + + + + For a device which allows hotplugging, you can use + snd_card_free_when_closed. This one will + postpone the destruction until all devices are closed. + + +

+ +
+ Some Hafta's + + The allocation of PCI resources is done in the + probe() function, and usually an extra + xxx_create() function is written for this + purpose. + + + + In the case of PCI devices, you first have to call + the pci_enable_device() function before + allocating resources. Also, you need to set the proper PCI DMA + mask to limit the accessed I/O range. In some cases, you might + need to call pci_set_master() function, + too. + + + + Suppose the 28bit mask, and the code to be added would be like: + + + + + + + +
+ +
+ Resource Allocation + + The allocation of I/O ports and irqs is done via standard kernel + functions. Unlike ALSA ver.0.5.x., there are no helpers for + that. And these resources must be released in the destructor + function (see below). Also, on ALSA 0.9.x, you don't need to + allocate (pseudo-)DMA for PCI like in ALSA 0.5.x. + + + + Now assume that the PCI device has an I/O port with 8 bytes + and an interrupt. Then struct mychip will have the + following fields: + + + + + + + + + + For an I/O port (and also a memory region), you need to have + the resource pointer for the standard resource management. For + an irq, you have to keep only the irq number (integer). But you + need to initialize this number as -1 before actual allocation, + since irq 0 is valid. The port address and its resource pointer + can be initialized as null by + kzalloc() automatically, so you + don't have to take care of resetting them. + + + + The allocation of an I/O port is done like this: + + + +port = pci_resource_start(pci, 0); +]]> + + + + + + + It will reserve the I/O port region of 8 bytes of the given + PCI device. The returned value, chip->res_port, is allocated + via kmalloc() by + request_region(). The pointer must be + released via kfree(), but there is a + problem with this. This issue will be explained later. + + + + The allocation of an interrupt source is done like this: + + + +irq, snd_mychip_interrupt, + IRQF_SHARED, "My Chip", chip)) { + printk(KERN_ERR "cannot grab irq %d\n", pci->irq); + snd_mychip_free(chip); + return -EBUSY; + } + chip->irq = pci->irq; +]]> + + + + where snd_mychip_interrupt() is the + interrupt handler defined later. + Note that chip->irq should be defined + only when request_irq() succeeded. + + + + On the PCI bus, interrupts can be shared. Thus, + IRQF_SHARED is used as the interrupt flag of + request_irq(). + + + + The last argument of request_irq() is the + data pointer passed to the interrupt handler. Usually, the + chip-specific record is used for that, but you can use what you + like, too. + + + + I won't give details about the interrupt handler at this + point, but at least its appearance can be explained now. The + interrupt handler looks usually like the following: + + + + + + + + + + Now let's write the corresponding destructor for the resources + above. The role of destructor is simple: disable the hardware + (if already activated) and release the resources. So far, we + have no hardware part, so the disabling code is not written here. + + + + To release the resources, the check-and-release + method is a safer way. For the interrupt, do like this: + + + +irq >= 0) + free_irq(chip->irq, chip); +]]> + + + + Since the irq number can start from 0, you should initialize + chip->irq with a negative value (e.g. -1), so that you can + check the validity of the irq number as above. + + + + When you requested I/O ports or memory regions via + pci_request_region() or + pci_request_regions() like in this example, + release the resource(s) using the corresponding function, + pci_release_region() or + pci_release_regions(). + + + +pci); +]]> + + + + + + When you requested manually via request_region() + or request_mem_region, you can release it via + release_resource(). Suppose that you keep + the resource pointer returned from request_region() + in chip->res_port, the release procedure looks like: + + + +res_port); +]]> + + + + + + Don't forget to call pci_disable_device() + before the end. + + + + And finally, release the chip-specific record. + + + + + + + + + + Again, remember that you cannot + use the __devexit prefix for this destructor. + + + + We didn't implement the hardware disabling part in the above. + If you need to do this, please note that the destructor may be + called even before the initialization of the chip is completed. + It would be better to have a flag to skip hardware disabling + if the hardware was not initialized yet. + + + + When the chip-data is assigned to the card using + snd_device_new() with + SNDRV_DEV_LOWLELVEL , its destructor is + called at the last. That is, it is assured that all other + components like PCMs and controls have already been released. + You don't have to stop PCMs, etc. explicitly, but just + call low-level hardware stopping. + + + + The management of a memory-mapped region is almost as same as + the management of an I/O port. You'll need three fields like + the following: + + + + + + + + and the allocation would be like below: + + + +iobase_phys = pci_resource_start(pci, 0); + chip->iobase_virt = ioremap_nocache(chip->iobase_phys, + pci_resource_len(pci, 0)); +]]> + + + + and the corresponding destructor would be: + + + +iobase_virt) + iounmap(chip->iobase_virt); + .... + pci_release_regions(chip->pci); + .... + } +]]> + + + + +
+ +
+ Registration of Device Struct + + At some point, typically after calling snd_device_new(), + you need to register the struct device of the chip + you're handling for udev and co. ALSA provides a macro for compatibility with + older kernels. Simply call like the following: + + +dev); +]]> + + + so that it stores the PCI's device pointer to the card. This will be + referred by ALSA core functions later when the devices are registered. + + + In the case of non-PCI, pass the proper device struct pointer of the BUS + instead. (In the case of legacy ISA without PnP, you don't have to do + anything.) + +
+ +
+ PCI Entries + + So far, so good. Let's finish the missing PCI + stuff. At first, we need a + pci_device_id table for this + chipset. It's a table of PCI vendor/device ID number, and some + masks. + + + + For example, + + + + + + + + + + The first and second fields of + the pci_device_id structure are the vendor and + device IDs. If you have no reason to filter the matching + devices, you can leave the remaining fields as above. The last + field of the pci_device_id struct contains + private data for this entry. You can specify any value here, for + example, to define specific operations for supported device IDs. + Such an example is found in the intel8x0 driver. + + + + The last entry of this list is the terminator. You must + specify this all-zero entry. + + + + Then, prepare the pci_driver record: + + + + + + + + + + The probe and + remove functions have already + been defined in the previous sections. + The remove function should + be defined with the + __devexit_p() macro, so that it's not + defined for built-in (and non-hot-pluggable) case. The + name + field is the name string of this device. Note that you must not + use a slash / in this string. + + + + And at last, the module entries: + + + + + + + + + + Note that these module entries are tagged with + __init and + __exit prefixes, not + __devinit nor + __devexit. + + + + Oh, one thing was forgotten. If you have no exported symbols, + you need to declare it in 2.2 or 2.4 kernels (it's not necessary in 2.6 kernels). + + + + + + + + That's all! + +
+ + + + + + + + PCM Interface + +
+ General + + The PCM middle layer of ALSA is quite powerful and it is only + necessary for each driver to implement the low-level functions + to access its hardware. + + + + For accessing to the PCM layer, you need to include + <sound/pcm.h> first. In addition, + <sound/pcm_params.h> might be needed + if you access to some functions related with hw_param. + + + + Each card device can have up to four pcm instances. A pcm + instance corresponds to a pcm device file. The limitation of + number of instances comes only from the available bit size of + the Linux's device numbers. Once when 64bit device number is + used, we'll have more pcm instances available. + + + + A pcm instance consists of pcm playback and capture streams, + and each pcm stream consists of one or more pcm substreams. Some + soundcards support multiple playback functions. For example, + emu10k1 has a PCM playback of 32 stereo substreams. In this case, at + each open, a free substream is (usually) automatically chosen + and opened. Meanwhile, when only one substream exists and it was + already opened, the successful open will either block + or error with EAGAIN according to the + file open mode. But you don't have to care about such details in your + driver. The PCM middle layer will take care of such work. + +

The first argument is the card pointer to which this + pcm is assigned, and the second is the ID string. + + + + The third argument (index, 0 in the + above) is the index of this new pcm. It begins from zero. If + you create more than one pcm instances, specify the + different numbers in this argument. For example, + index = 1 for the second PCM device. + + + + The fourth and fifth arguments are the number of substreams + for playback and capture, respectively. Here 1 is used for + both arguments. When no playback or capture substreams are available, + pass 0 to the corresponding argument. + + + + If a chip supports multiple playbacks or captures, you can + specify more numbers, but they must be handled properly in + open/close, etc. callbacks. When you need to know which + substream you are referring to, then it can be obtained from + struct snd_pcm_substream data passed to each callback + as follows: + + + +number; +]]> + + + + + + After the pcm is created, you need to set operators for each + pcm stream. + + + + + + + + + + The operators are defined typically like this: + + + + + + + + All the callbacks are described in the + + Operators subsection. + + + + After setting the operators, you probably will want to + pre-allocate the buffer. For the pre-allocation, simply call + the following: + + + +pci), + 64*1024, 64*1024); +]]> + + + + It will allocate a buffer up to 64kB as default. + Buffer management details will be described in the later section Buffer and Memory + Management. + + + + Additionally, you can set some extra information for this pcm + in pcm->info_flags. + The available values are defined as + SNDRV_PCM_INFO_XXX in + <sound/asound.h>, which is used for + the hardware definition (described later).

+ +
+ ... And the Destructor? + + The destructor for a pcm instance is not always + necessary. Since the pcm device will be released by the middle + layer code automatically, you don't have to call the destructor + explicitly. + + + + The destructor would be necessary if you created + special records internally and needed to release them.

+ +
+ Runtime Pointer - The Chest of PCM Information + + When the PCM substream is opened, a PCM runtime instance is + allocated and assigned to the substream. This pointer is + accessible via substream->runtime. + This runtime pointer holds most information you need + to control the PCM: the copy of hw_params and sw_params configurations, the buffer + pointers, mmap records, spinlocks, etc. + + + + The definition of runtime instance is found in + <sound/pcm.h>. Here are + the contents of this file: + + + + + + + + + For the operators (callbacks) of each sound driver, most of + these records are supposed to be read-only. Only the PCM + middle-layer changes / updates them. The exceptions are + the hardware description (hw), interrupt callbacks + (transfer_ack_xxx), DMA buffer information, and the private + data. Besides, if you use the standard buffer allocation + method via snd_pcm_lib_malloc_pages(), + you don't need to set the DMA buffer information by yourself. + + + + In the sections below, important records are explained. + + +
+ Hardware Description + + The hardware descriptor (struct snd_pcm_hardware) + contains the definitions of the fundamental hardware + configuration. Above all, you'll need to define this in + + the open callback. + Note that the runtime instance holds the copy of the + descriptor, not the pointer to the existing descriptor. That + is, in the open callback, you can modify the copied descriptor + (runtime->hw) as you need. For example, if the maximum + number of channels is 1 only on some chip models, you can + still use the same hardware descriptor and change the + channels_max later: + + +runtime; + ... + runtime->hw = snd_mychip_playback_hw; /* common definition */ + if (chip->model == VERY_OLD_ONE) + runtime->hw.channels_max = 1; +]]> + + + + + + Typically, you'll have a hardware descriptor as below: + + + + + + + + + + + The info field contains the type and + capabilities of this pcm. The bit flags are defined in + <sound/asound.h> as + SNDRV_PCM_INFO_XXX. Here, at least, you + have to specify whether the mmap is supported and which + interleaved format is supported. + When the is supported, add the + SNDRV_PCM_INFO_MMAP flag here. When the + hardware supports the interleaved or the non-interleaved + formats, SNDRV_PCM_INFO_INTERLEAVED or + SNDRV_PCM_INFO_NONINTERLEAVED flag must + be set, respectively. If both are supported, you can set both, + too. + + + + In the above example, MMAP_VALID and + BLOCK_TRANSFER are specified for the OSS mmap + mode. Usually both are set. Of course, + MMAP_VALID is set only if the mmap is + really supported. + + + + The other possible flags are + SNDRV_PCM_INFO_PAUSE and + SNDRV_PCM_INFO_RESUME. The + PAUSE bit means that the pcm supports the + pause operation, while the + RESUME bit means that the pcm supports + the full suspend/resume operation. + If the PAUSE flag is set, + the trigger callback below + must handle the corresponding (pause push/release) commands. + The suspend/resume trigger commands can be defined even without + the RESUME flag. See + Power Management section for details. + + + + When the PCM substreams can be synchronized (typically, + synchronized start/stop of a playback and a capture streams), + you can give SNDRV_PCM_INFO_SYNC_START, + too. In this case, you'll need to check the linked-list of + PCM substreams in the trigger callback. This will be + described in the later section. + + + + + + formats field contains the bit-flags + of supported formats (SNDRV_PCM_FMTBIT_XXX). + If the hardware supports more than one format, give all or'ed + bits. In the example above, the signed 16bit little-endian + format is specified. + + + + + + rates field contains the bit-flags of + supported rates (SNDRV_PCM_RATE_XXX). + When the chip supports continuous rates, pass + CONTINUOUS bit additionally. + The pre-defined rate bits are provided only for typical + rates. If your chip supports unconventional rates, you need to add + the KNOT bit and set up the hardware + constraint manually (explained later). + + + + + + rate_min and + rate_max define the minimum and + maximum sample rate. This should correspond somehow to + rates bits. + + + + + + channel_min and + channel_max + define, as you might already expected, the minimum and maximum + number of channels. + + + + + + buffer_bytes_max defines the + maximum buffer size in bytes. There is no + buffer_bytes_min field, since + it can be calculated from the minimum period size and the + minimum number of periods. + Meanwhile, period_bytes_min and + define the minimum and maximum size of the period in bytes. + periods_max and + periods_min define the maximum and + minimum number of periods in the buffer. + + + + The period is a term that corresponds to + a fragment in the OSS world. The period defines the size at + which a PCM interrupt is generated. This size strongly + depends on the hardware. + Generally, the smaller period size will give you more + interrupts, that is, more controls. + In the case of capture, this size defines the input latency. + On the other hand, the whole buffer size defines the + output latency for the playback direction. + + + + + + There is also a field fifo_size. + This specifies the size of the hardware FIFO, but currently it + is neither used in the driver nor in the alsa-lib. So, you + can ignore this field. + + + + +
+ +
+ PCM Configurations + + Ok, let's go back again to the PCM runtime records. + The most frequently referred records in the runtime instance are + the PCM configurations. + The PCM configurations are stored in the runtime instance + after the application sends hw_params data via + alsa-lib. There are many fields copied from hw_params and + sw_params structs. For example, + format holds the format type + chosen by the application. This field contains the enum value + SNDRV_PCM_FORMAT_XXX. + + + + One thing to be noted is that the configured buffer and period + sizes are stored in frames in the runtime. + In the ALSA world, 1 frame = channels * samples-size. + For conversion between frames and bytes, you can use the + frames_to_bytes() and + bytes_to_frames() helper functions. + + +period_size); +]]> + + + + + + Also, many software parameters (sw_params) are + stored in frames, too. Please check the type of the field. + snd_pcm_uframes_t is for the frames as unsigned + integer while snd_pcm_sframes_t is for the frames + as signed integer. + +
+ +
+ DMA Buffer Information + + The DMA buffer is defined by the following four fields, + dma_area, + dma_addr, + dma_bytes and + dma_private. + The dma_area holds the buffer + pointer (the logical address). You can call + memcpy from/to + this pointer. Meanwhile, dma_addr + holds the physical address of the buffer. This field is + specified only when the buffer is a linear buffer. + dma_bytes holds the size of buffer + in bytes. dma_private is used for + the ALSA DMA allocator. + + + + If you use a standard ALSA function, + snd_pcm_lib_malloc_pages(), for + allocating the buffer, these fields are set by the ALSA middle + layer, and you should not change them by + yourself. You can read them but not write them. + On the other hand, if you want to allocate the buffer by + yourself, you'll need to manage it in hw_params callback. + At least, dma_bytes is mandatory. + dma_area is necessary when the + buffer is mmapped. If your driver doesn't support mmap, this + field is not necessary. dma_addr + is also optional. You can use + dma_private as you like, too. + +
+ +
+ Running Status + + The running status can be referred via runtime->status. + This is the pointer to the struct snd_pcm_mmap_status + record. For example, you can get the current DMA hardware + pointer via runtime->status->hw_ptr. + + + + The DMA application pointer can be referred via + runtime->control, which points to the + struct snd_pcm_mmap_control record. + However, accessing directly to this value is not recommended. + +
+ +
+ Private Data + + You can allocate a record for the substream and store it in + runtime->private_data. Usually, this + is done in + + the open callback. + Don't mix this with pcm->private_data. + The pcm->private_data usually points to the + chip instance assigned statically at the creation of PCM, while the + runtime->private_data points to a dynamic + data structure created at the PCM open callback. + + + +runtime->private_data = data; + .... + } +]]> + + + + + + The allocated object must be released in + + the close callback. + +
+ +
+ Interrupt Callbacks + + The field transfer_ack_begin and + transfer_ack_end are called at + the beginning and at the end of + snd_pcm_period_elapsed(), respectively. + +
+ +
+ +
+ Operators + + OK, now let me give details about each pcm callback + (ops). In general, every callback must + return 0 if successful, or a negative error number + such as -EINVAL. To choose an appropriate + error number, it is advised to check what value other parts of + the kernel return when the same kind of request fails. + + + + The callback function takes at least the argument with + snd_pcm_substream pointer. To retrieve + the chip record from the given substream instance, you can use the + following macro. + + + + + + + + The macro reads substream->private_data, + which is a copy of pcm->private_data. + You can override the former if you need to assign different data + records per PCM substream. For example, the cmi8330 driver assigns + different private_data for playback and capture directions, + because it uses two different codecs (SB- and AD-compatible) for + different directions. + + +
+ open callback + + + + + + + + This is called when a pcm substream is opened. + + + + At least, here you have to initialize the runtime->hw + record. Typically, this is done by like this: + + + +runtime; + + runtime->hw = snd_mychip_playback_hw; + return 0; + } +]]> + + + + where snd_mychip_playback_hw is the + pre-defined hardware description. + + + + You can allocate a private data in this callback, as described + in + Private Data section. + + + + If the hardware configuration needs more constraints, set the + hardware constraints here, too. + See + Constraints for more details. + +
+ +
+ close callback + + + + + + + + Obviously, this is called when a pcm substream is closed. + + + + Any private instance for a pcm substream allocated in the + open callback will be released here. + + + +runtime->private_data); + .... + } +]]> + + + +
+ +
+ ioctl callback + + This is used for any special call to pcm ioctls. But + usually you can pass a generic ioctl callback, + snd_pcm_lib_ioctl. + +
+ +
+ hw_params callback + + + + + + + + + + This is called when the hardware parameter + (hw_params) is set + up by the application, + that is, once when the buffer size, the period size, the + format, etc. are defined for the pcm substream. + + + + Many hardware setups should be done in this callback, + including the allocation of buffers. + + + + Parameters to be initialized are retrieved by + params_xxx() macros. To allocate + buffer, you can call a helper function, + + + + + + + + snd_pcm_lib_malloc_pages() is available + only when the DMA buffers have been pre-allocated. + See the section + Buffer Types for more details. + + + + Note that this and prepare callbacks + may be called multiple times per initialization. + For example, the OSS emulation may + call these callbacks at each change via its ioctl. + + + + Thus, you need to be careful not to allocate the same buffers + many times, which will lead to memory leaks! Calling the + helper function above many times is OK. It will release the + previous buffer automatically when it was already allocated. + + + + Another note is that this callback is non-atomic + (schedulable). This is important, because the + trigger callback + is atomic (non-schedulable). That is, mutexes or any + schedule-related functions are not available in + trigger callback. + Please see the subsection + + Atomicity for details. + +
+ +
+ hw_free callback + + + + + + + + + + This is called to release the resources allocated via + hw_params. For example, releasing the + buffer via + snd_pcm_lib_malloc_pages() is done by + calling the following: + + + + + + + + + + This function is always called before the close callback is called. + Also, the callback may be called multiple times, too. + Keep track whether the resource was already released. + +
+ +
+ prepare callback + + + + + + + + + + This callback is called when the pcm is + prepared. You can set the format type, sample + rate, etc. here. The difference from + hw_params is that the + prepare callback will be called each + time + snd_pcm_prepare() is called, i.e. when + recovering after underruns, etc. + + + + Note that this callback is now non-atomic. + You can use schedule-related functions safely in this callback. + + + + In this and the following callbacks, you can refer to the + values via the runtime record, + substream->runtime. + For example, to get the current + rate, format or channels, access to + runtime->rate, + runtime->format or + runtime->channels, respectively. + The physical address of the allocated buffer is set to + runtime->dma_area. The buffer and period sizes are + in runtime->buffer_size and runtime->period_size, + respectively. + + + + Be careful that this callback will be called many times at + each setup, too. + +
+ +
+ trigger callback + + + + + + + + This is called when the pcm is started, stopped or paused. + + + + Which action is specified in the second argument, + SNDRV_PCM_TRIGGER_XXX in + <sound/pcm.h>. At least, + the START and STOP + commands must be defined in this callback. + + + + + + + + + + When the pcm supports the pause operation (given in the info + field of the hardware table), the PAUSE_PUSE + and PAUSE_RELEASE commands must be + handled here, too. The former is the command to pause the pcm, + and the latter to restart the pcm again. + + + + When the pcm supports the suspend/resume operation, + regardless of full or partial suspend/resume support, + the SUSPEND and RESUME + commands must be handled, too. + These commands are issued when the power-management status is + changed. Obviously, the SUSPEND and + RESUME commands + suspend and resume the pcm substream, and usually, they + are identical to the STOP and + START commands, respectively. + See the + Power Management section for details. + + + + As mentioned, this callback is atomic. You cannot call + functions which may sleep. + The trigger callback should be as minimal as possible, + just really triggering the DMA. The other stuff should be + initialized hw_params and prepare callbacks properly + beforehand. + +
+ +
+ pointer callback + + + + + + + + This callback is called when the PCM middle layer inquires + the current hardware position on the buffer. The position must + be returned in frames, + ranging from 0 to buffer_size - 1. + + + + This is called usually from the buffer-update routine in the + pcm middle layer, which is invoked when + snd_pcm_period_elapsed() is called in the + interrupt routine. Then the pcm middle layer updates the + position and calculates the available space, and wakes up the + sleeping poll threads, etc. + + + + This callback is also atomic. + +
+ +
+ copy and silence callbacks + + These callbacks are not mandatory, and can be omitted in + most cases. These callbacks are used when the hardware buffer + cannot be in the normal memory space. Some chips have their + own buffer on the hardware which is not mappable. In such a + case, you have to transfer the data manually from the memory + buffer to the hardware buffer. Or, if the buffer is + non-contiguous on both physical and virtual memory spaces, + these callbacks must be defined, too. + + + + If these two callbacks are defined, copy and set-silence + operations are done by them. The detailed will be described in + the later section Buffer and Memory + Management. + +
+ +
+ ack callback + + This callback is also not mandatory. This callback is called + when the appl_ptr is updated in read or write operations. + Some drivers like emu10k1-fx and cs46xx need to track the + current appl_ptr for the internal buffer, and this callback + is useful only for such a purpose. + + + This callback is atomic. + +
+ +
+ page callback + + + This callback is optional too. This callback is used + mainly for non-contiguous buffers. The mmap calls this + callback to get the page address. Some examples will be + explained in the later section Buffer and Memory + Management, too. + +
+
+ +
+ Interrupt Handler + + The rest of pcm stuff is the PCM interrupt handler. The + role of PCM interrupt handler in the sound driver is to update + the buffer position and to tell the PCM middle layer when the + buffer position goes across the prescribed period size. To + inform this, call the snd_pcm_period_elapsed() + function. + + + + There are several types of sound chips to generate the interrupts. + + +
+ Interrupts at the period (fragment) boundary + + This is the most frequently found type: the hardware + generates an interrupt at each period boundary. + In this case, you can call + snd_pcm_period_elapsed() at each + interrupt. + + + + snd_pcm_period_elapsed() takes the + substream pointer as its argument. Thus, you need to keep the + substream pointer accessible from the chip instance. For + example, define substream field in the chip record to hold the + current running substream pointer, and set the pointer value + at open callback (and reset at close callback). + + + + If you acquire a spinlock in the interrupt handler, and the + lock is used in other pcm callbacks, too, then you have to + release the lock before calling + snd_pcm_period_elapsed(), because + snd_pcm_period_elapsed() calls other pcm + callbacks inside. + + + + Typical code would be like: + + + Interrupt Handler Case #1 + +lock); + .... + if (pcm_irq_invoked(chip)) { + /* call updater, unlock before it */ + spin_unlock(&chip->lock); + snd_pcm_period_elapsed(chip->substream); + spin_lock(&chip->lock); + /* acknowledge the interrupt if necessary */ + } + .... + spin_unlock(&chip->lock); + return IRQ_HANDLED; + } +]]> + + + +
+ +
+ High frequency timer interrupts + + This happense when the hardware doesn't generate interrupts + at the period boundary but issues timer interrupts at a fixed + timer rate (e.g. es1968 or ymfpci drivers). + In this case, you need to check the current hardware + position and accumulate the processed sample length at each + interrupt. When the accumulated size exceeds the period + size, call + snd_pcm_period_elapsed() and reset the + accumulator. + + + + Typical code would be like the following. + + + Interrupt Handler Case #2 + +lock); + .... + if (pcm_irq_invoked(chip)) { + unsigned int last_ptr, size; + /* get the current hardware pointer (in frames) */ + last_ptr = get_hw_ptr(chip); + /* calculate the processed frames since the + * last update + */ + if (last_ptr < chip->last_ptr) + size = runtime->buffer_size + last_ptr + - chip->last_ptr; + else + size = last_ptr - chip->last_ptr; + /* remember the last updated point */ + chip->last_ptr = last_ptr; + /* accumulate the size */ + chip->size += size; + /* over the period boundary? */ + if (chip->size >= runtime->period_size) { + /* reset the accumulator */ + chip->size %= runtime->period_size; + /* call updater */ + spin_unlock(&chip->lock); + snd_pcm_period_elapsed(substream); + spin_lock(&chip->lock); + } + /* acknowledge the interrupt if necessary */ + } + .... + spin_unlock(&chip->lock); + return IRQ_HANDLED; + } +]]> + + + +
+ +
+ On calling <function>snd_pcm_period_elapsed()</function> + + In both cases, even if more than one period are elapsed, you + don't have to call + snd_pcm_period_elapsed() many times. Call + only once. And the pcm layer will check the current hardware + pointer and update to the latest status. + +
+
+ +
+ Atomicity + + One of the most important (and thus difficult to debug) problems + in kernel programming are race conditions. + In the Linux kernel, they are usually avoided via spin-locks, mutexes + or semaphores. In general, if a race condition can happen + in an interrupt handler, it has to be managed atomically, and you + have to use a spinlock to protect the critical session. If the + critical section is not in interrupt handler code and + if taking a relatively long time to execute is acceptable, you + should use mutexes or semaphores instead. + + + + As already seen, some pcm callbacks are atomic and some are + not. For example, the hw_params callback is + non-atomic, while trigger callback is + atomic. This means, the latter is called already in a spinlock + held by the PCM middle layer. Please take this atomicity into + account when you choose a locking scheme in the callbacks. + + + + In the atomic callbacks, you cannot use functions which may call + schedule or go to + sleep. Semaphores and mutexes can sleep, + and hence they cannot be used inside the atomic callbacks + (e.g. trigger callback). + To implement some delay in such a callback, please use + udelay() or mdelay(). + + + + All three atomic callbacks (trigger, pointer, and ack) are + called with local interrupts disabled. + + +
+
+ Constraints + + If your chip supports unconventional sample rates, or only the + limited samples, you need to set a constraint for the + condition. + + + + For example, in order to restrict the sample rates in the some + supported values, use + snd_pcm_hw_constraint_list(). + You need to call this function in the open callback. + + + Example of Hardware Constraints + +runtime, 0, + SNDRV_PCM_HW_PARAM_RATE, + &constraints_rates); + if (err < 0) + return err; + .... + } +]]> + + + + + + There are many different constraints. + Look at sound/pcm.h for a complete list. + You can even define your own constraint rules. + For example, let's suppose my_chip can manage a substream of 1 channel + if and only if the format is S16_LE, otherwise it supports any format + specified in the snd_pcm_hardware structure (or in any + other constraint_list). You can build a rule like this: + + + Example of Hardware Constraints for Channels + +min < 2) { + fmt.bits[0] &= SNDRV_PCM_FMTBIT_S16_LE; + return snd_mask_refine(f, &fmt); + } + return 0; + } +]]> + + + + + + Then you need to call this function to add your rule: + + + +runtime, 0, SNDRV_PCM_HW_PARAM_CHANNELS, + hw_rule_channels_by_format, 0, SNDRV_PCM_HW_PARAM_FORMAT, + -1); +]]> + + + + + + The rule function is called when an application sets the number of + channels. But an application can set the format before the number of + channels. Thus you also need to define the inverse rule: + + + Example of Hardware Constraints for Channels + +bits[0] == SNDRV_PCM_FMTBIT_S16_LE) { + ch.min = ch.max = 1; + ch.integer = 1; + return snd_interval_refine(c, &ch); + } + return 0; + } +]]> + + + + + + ...and in the open callback: + + +runtime, 0, SNDRV_PCM_HW_PARAM_FORMAT, + hw_rule_format_by_channels, 0, SNDRV_PCM_HW_PARAM_CHANNELS, + -1); +]]> + + + + + + I won't give more details here, rather I + would like to say, Luke, use the source. + +
+ + + + + + + + + Control Interface + +
+ General + + The control interface is used widely for many switches, + sliders, etc. which are accessed from user-space. Its most + important use is the mixer interface. In other words, since ALSA + 0.9.x, all the mixer stuff is implemented on the control kernel API. + + + + ALSA has a well-defined AC97 control module. If your chip + supports only the AC97 and nothing else, you can skip this + section. + + + + The control API is defined in + <sound/control.h>. + Include this file if you want to add your own controls. + +
+ +
+ Definition of Controls + + To create a new control, you need to define the + following three + callbacks: info, + get and + put. Then, define a + struct snd_kcontrol_new record, such as: + + + Definition of a Control + + + + + + + + Most likely the control is created via + snd_ctl_new1(), and in such a case, you can + add the __devinitdata prefix to the + definition as above. + + + + The iface field specifies the control + type, SNDRV_CTL_ELEM_IFACE_XXX, which + is usually MIXER. + Use CARD for global controls that are not + logically part of the mixer. + If the control is closely associated with some specific device on + the sound card, use HWDEP, + PCM, RAWMIDI, + TIMER, or SEQUENCER, and + specify the device number with the + device and + subdevice fields. + + + + The name is the name identifier + string. Since ALSA 0.9.x, the control name is very important, + because its role is classified from its name. There are + pre-defined standard control names. The details are described in + the + Control Names subsection. + + + + The index field holds the index number + of this control. If there are several different controls with + the same name, they can be distinguished by the index + number. This is the case when + several codecs exist on the card. If the index is zero, you can + omit the definition above. + + + + The access field contains the access + type of this control. Give the combination of bit masks, + SNDRV_CTL_ELEM_ACCESS_XXX, there. + The details will be explained in + the + Access Flags subsection. + + + + The private_value field contains + an arbitrary long integer value for this record. When using + the generic info, + get and + put callbacks, you can pass a value + through this field. If several small numbers are necessary, you can + combine them in bitwise. Or, it's possible to give a pointer + (casted to unsigned long) of some record to this field, too. + + + + The tlv field can be used to provide + metadata about the control; see the + + Metadata subsection. + + + + The other three are + + callback functions. + +
+ +
+ Control Names + + There are some standards to define the control names. A + control is usually defined from the three parts as + SOURCE DIRECTION FUNCTION. + + + + The first, SOURCE, specifies the source + of the control, and is a string such as Master, + PCM, CD and + Line. There are many pre-defined sources. + + + + The second, DIRECTION, is one of the + following strings according to the direction of the control: + Playback, Capture, Bypass + Playback and Bypass Capture. Or, it can + be omitted, meaning both playback and capture directions. + + + + The third, FUNCTION, is one of the + following strings according to the function of the control: + Switch, Volume and + Route. + + + + The example of control names are, thus, Master Capture + Switch or PCM Playback Volume. + + + + There are some exceptions: + + +
+ Global capture and playback + + Capture Source, Capture Switch + and Capture Volume are used for the global + capture (input) source, switch and volume. Similarly, + Playback Switch and Playback + Volume are used for the global output gain switch and + volume. + +
+ +
+ Tone-controls + + tone-control switch and volumes are specified like + Tone Control - XXX, e.g. Tone Control - + Switch, Tone Control - Bass, + Tone Control - Center. + +
+ +
+ 3D controls + + 3D-control switches and volumes are specified like 3D + Control - XXX, e.g. 3D Control - + Switch, 3D Control - Center, 3D + Control - Space. + +
+ +
+ Mic boost + + Mic-boost switch is set as Mic Boost or + Mic Boost (6dB). + + + + More precise information can be found in + Documentation/sound/alsa/ControlNames.txt. + +
+
+ +
+ Access Flags + + + The access flag is the bitmask which specifies the access type + of the given control. The default access type is + SNDRV_CTL_ELEM_ACCESS_READWRITE, + which means both read and write are allowed to this control. + When the access flag is omitted (i.e. = 0), it is + considered as READWRITE access as default. + + + + When the control is read-only, pass + SNDRV_CTL_ELEM_ACCESS_READ instead. + In this case, you don't have to define + the put callback. + Similarly, when the control is write-only (although it's a rare + case), you can use the WRITE flag instead, and + you don't need the get callback. + + + + If the control value changes frequently (e.g. the VU meter), + VOLATILE flag should be given. This means + that the control may be changed without + + notification. Applications should poll such + a control constantly. + + + + When the control is inactive, set + the INACTIVE flag, too. + There are LOCK and + OWNER flags to change the write + permissions. + + +
+ +
+ Callbacks + +
+ info callback + + The info callback is used to get + detailed information on this control. This must store the + values of the given struct snd_ctl_elem_info + object. For example, for a boolean control with a single + element: + + + Example of info callback + +type = SNDRV_CTL_ELEM_TYPE_BOOLEAN; + uinfo->count = 1; + uinfo->value.integer.min = 0; + uinfo->value.integer.max = 1; + return 0; + } +]]> + + + + + + The type field specifies the type + of the control. There are BOOLEAN, + INTEGER, ENUMERATED, + BYTES, IEC958 and + INTEGER64. The + count field specifies the + number of elements in this control. For example, a stereo + volume would have count = 2. The + value field is a union, and + the values stored are depending on the type. The boolean and + integer types are identical. + + + + The enumerated type is a bit different from others. You'll + need to set the string for the currently given item index. + + + +type = SNDRV_CTL_ELEM_TYPE_ENUMERATED; + uinfo->count = 1; + uinfo->value.enumerated.items = 4; + if (uinfo->value.enumerated.item > 3) + uinfo->value.enumerated.item = 3; + strcpy(uinfo->value.enumerated.name, + texts[uinfo->value.enumerated.item]); + return 0; + } +]]> + + + + + + Some common info callbacks are available for your convenience: + snd_ctl_boolean_mono_info() and + snd_ctl_boolean_stereo_info(). + Obviously, the former is an info callback for a mono channel + boolean item, just like snd_myctl_mono_info + above, and the latter is for a stereo channel boolean item. + + +
+ +
+ get callback + + + This callback is used to read the current value of the + control and to return to user-space. + + + + For example, + + + Example of get callback + +value.integer.value[0] = get_some_value(chip); + return 0; + } +]]> + + + + + + The value field depends on + the type of control as well as on the info callback. For example, + the sb driver uses this field to store the register offset, + the bit-shift and the bit-mask. The + private_value field is set as follows: + + + + + + and is retrieved in callbacks like + + +private_value & 0xff; + int shift = (kcontrol->private_value >> 16) & 0xff; + int mask = (kcontrol->private_value >> 24) & 0xff; + .... + } +]]> + + + + + + In the get callback, + you have to fill all the elements if the + control has more than one elements, + i.e. count > 1. + In the example above, we filled only one element + (value.integer.value[0]) since it's + assumed as count = 1. + +
+ +
+ put callback + + + This callback is used to write a value from user-space. + + + + For example, + + + Example of put callback + +current_value != + ucontrol->value.integer.value[0]) { + change_current_value(chip, + ucontrol->value.integer.value[0]); + changed = 1; + } + return changed; + } +]]> + + + + As seen above, you have to return 1 if the value is + changed. If the value is not changed, return 0 instead. + If any fatal error happens, return a negative error code as + usual. + + + + As in the get callback, + when the control has more than one elements, + all elements must be evaluated in this callback, too. + +
+ +
+ Callbacks are not atomic + + All these three callbacks are basically not atomic. + +
+
+ +
+ Constructor + + When everything is ready, finally we can create a new + control. To create a control, there are two functions to be + called, snd_ctl_new1() and + snd_ctl_add(). + + + + In the simplest way, you can do like this: + + + + + + + + where my_control is the + struct snd_kcontrol_new object defined above, and chip + is the object pointer to be passed to + kcontrol->private_data + which can be referred to in callbacks. + + + + snd_ctl_new1() allocates a new + snd_kcontrol instance (that's why the definition + of my_control can be with + the __devinitdata + prefix), and snd_ctl_add assigns the given + control component to the card. + +
+ +
+ Change Notification + + If you need to change and update a control in the interrupt + routine, you can call snd_ctl_notify(). For + example, + + + + + + + + This function takes the card pointer, the event-mask, and the + control id pointer for the notification. The event-mask + specifies the types of notification, for example, in the above + example, the change of control values is notified. + The id pointer is the pointer of struct snd_ctl_elem_id + to be notified. + You can find some examples in es1938.c or + es1968.c for hardware volume interrupts. + +
+ +
+ Metadata + + To provide information about the dB values of a mixer control, use + on of the DECLARE_TLV_xxx macros from + <sound/tlv.h> to define a variable + containing this information, set thetlv.p + field to point to this variable, and include the + SNDRV_CTL_ELEM_ACCESS_TLV_READ flag in the + access field; like this: + + + + + + + + + The DECLARE_TLV_DB_SCALE macro defines + information about a mixer control where each step in the control's + value changes the dB value by a constant dB amount. + The first parameter is the name of the variable to be defined. + The second parameter is the minimum value, in units of 0.01 dB. + The third parameter is the step size, in units of 0.01 dB. + Set the fourth parameter to 1 if the minimum value actually mutes + the control. + + + + The DECLARE_TLV_DB_LINEAR macro defines + information about a mixer control where the control's value affects + the output linearly. + The first parameter is the name of the variable to be defined. + The second parameter is the minimum value, in units of 0.01 dB. + The third parameter is the maximum value, in units of 0.01 dB. + If the minimum value mutes the control, set the second parameter to + TLV_DB_GAIN_MUTE. + +
+ + + + + + + + + API for AC97 Codec + +
+ General + + The ALSA AC97 codec layer is a well-defined one, and you don't + have to write much code to control it. Only low-level control + routines are necessary. The AC97 codec API is defined in + <sound/ac97_codec.h>. + +
+ +
+ Full Code Example + + + Example of AC97 Interface + +private_data; + .... + /* read a register value here from the codec */ + return the_register_value; + } + + static void snd_mychip_ac97_write(struct snd_ac97 *ac97, + unsigned short reg, unsigned short val) + { + struct mychip *chip = ac97->private_data; + .... + /* write the given register value to the codec */ + } + + static int snd_mychip_ac97(struct mychip *chip) + { + struct snd_ac97_bus *bus; + struct snd_ac97_template ac97; + int err; + static struct snd_ac97_bus_ops ops = { + .write = snd_mychip_ac97_write, + .read = snd_mychip_ac97_read, + }; + + err = snd_ac97_bus(chip->card, 0, &ops, NULL, &bus); + if (err < 0) + return err; + memset(&ac97, 0, sizeof(ac97)); + ac97.private_data = chip; + return snd_ac97_mixer(bus, &ac97, &chip->ac97); + } + +]]> + + + +
+ +
+ Constructor + + To create an ac97 instance, first call snd_ac97_bus + with an ac97_bus_ops_t record with callback functions. + + + + + + + + The bus record is shared among all belonging ac97 instances. + + + + And then call snd_ac97_mixer() with an + struct snd_ac97_template + record together with the bus pointer created above. + + + +ac97); +]]> + + + + where chip->ac97 is a pointer to a newly created + ac97_t instance. + In this case, the chip pointer is set as the private data, so that + the read/write callback functions can refer to this chip instance. + This instance is not necessarily stored in the chip + record. If you need to change the register values from the + driver, or need the suspend/resume of ac97 codecs, keep this + pointer to pass to the corresponding functions. + +
+ +
+ Callbacks + + The standard callbacks are read and + write. Obviously they + correspond to the functions for read and write accesses to the + hardware low-level codes. + + + + The read callback returns the + register value specified in the argument. + + + +private_data; + .... + return the_register_value; + } +]]> + + + + Here, the chip can be cast from ac97->private_data. + + + + Meanwhile, the write callback is + used to set the register value. + + + + + + + + + + These callbacks are non-atomic like the control API callbacks. + + + + There are also other callbacks: + reset, + wait and + init. + + + + The reset callback is used to reset + the codec. If the chip requires a special kind of reset, you can + define this callback. + + + + The wait callback is used to + add some waiting time in the standard initialization of the codec. If the + chip requires the extra waiting time, define this callback. + + + + The init callback is used for + additional initialization of the codec. + +
+ +
+ Updating Registers in The Driver + + If you need to access to the codec from the driver, you can + call the following functions: + snd_ac97_write(), + snd_ac97_read(), + snd_ac97_update() and + snd_ac97_update_bits(). + + + + Both snd_ac97_write() and + snd_ac97_update() functions are used to + set a value to the given register + (AC97_XXX). The difference between them is + that snd_ac97_update() doesn't write a + value if the given value has been already set, while + snd_ac97_write() always rewrites the + value. + + + + + + + + + + snd_ac97_read() is used to read the value + of the given register. For example, + + + + + + + + + + snd_ac97_update_bits() is used to update + some bits in the given register. + + + + + + + + + + Also, there is a function to change the sample rate (of a + given register such as + AC97_PCM_FRONT_DAC_RATE) when VRA or + DRA is supported by the codec: + snd_ac97_set_rate(). + + + + + + + + + + The following registers are available to set the rate: + AC97_PCM_MIC_ADC_RATE, + AC97_PCM_FRONT_DAC_RATE, + AC97_PCM_LR_ADC_RATE, + AC97_SPDIF. When + AC97_SPDIF is specified, the register is + not really changed but the corresponding IEC958 status bits will + be updated. + +
+ +
+ Clock Adjustment + + In some chips, the clock of the codec isn't 48000 but using a + PCI clock (to save a quartz!). In this case, change the field + bus->clock to the corresponding + value. For example, intel8x0 + and es1968 drivers have their own function to read from the clock. + +
+ +
+ Proc Files + + The ALSA AC97 interface will create a proc file such as + /proc/asound/card0/codec97#0/ac97#0-0 and + ac97#0-0+regs. You can refer to these files to + see the current status and registers of the codec. + +
+ +
+ Multiple Codecs + + When there are several codecs on the same card, you need to + call snd_ac97_mixer() multiple times with + ac97.num=1 or greater. The num field + specifies the codec number. + + + + If you set up multiple codecs, you either need to write + different callbacks for each codec or check + ac97->num in the callback routines. + +
+ + + + + + + + + MIDI (MPU401-UART) Interface + +
+ General + + Many soundcards have built-in MIDI (MPU401-UART) + interfaces. When the soundcard supports the standard MPU401-UART + interface, most likely you can use the ALSA MPU401-UART API. The + MPU401-UART API is defined in + <sound/mpu401.h>. + + + + Some soundchips have a similar but slightly different + implementation of mpu401 stuff. For example, emu10k1 has its own + mpu401 routines. + +
+ +
+ Constructor + + To create a rawmidi object, call + snd_mpu401_uart_new(). + + + + + + + + + + The first argument is the card pointer, and the second is the + index of this component. You can create up to 8 rawmidi + devices. + + + + The third argument is the type of the hardware, + MPU401_HW_XXX. If it's not a special one, + you can use MPU401_HW_MPU401. + + + + The 4th argument is the I/O port address. Many + backward-compatible MPU401 have an I/O port such as 0x330. Or, it + might be a part of its own PCI I/O region. It depends on the + chip design. + + + + The 5th argument is a bitflag for additional information. + When the I/O port address above is part of the PCI I/O + region, the MPU401 I/O port might have been already allocated + (reserved) by the driver itself. In such a case, pass a bit flag + MPU401_INFO_INTEGRATED, + and the mpu401-uart layer will allocate the I/O ports by itself. + + + + When the controller supports only the input or output MIDI stream, + pass the MPU401_INFO_INPUT or + MPU401_INFO_OUTPUT bitflag, respectively. + Then the rawmidi instance is created as a single stream. + + + + MPU401_INFO_MMIO bitflag is used to change + the access method to MMIO (via readb and writeb) instead of + iob and outb. In this case, you have to pass the iomapped address + to snd_mpu401_uart_new(). + + + + When MPU401_INFO_TX_IRQ is set, the output + stream isn't checked in the default interrupt handler. The driver + needs to call snd_mpu401_uart_interrupt_tx() + by itself to start processing the output stream in the irq handler. + + + + Usually, the port address corresponds to the command port and + port + 1 corresponds to the data port. If not, you may change + the cport field of + struct snd_mpu401 manually + afterward. However, snd_mpu401 pointer is not + returned explicitly by + snd_mpu401_uart_new(). You need to cast + rmidi->private_data to + snd_mpu401 explicitly, + + + +private_data; +]]> + + + + and reset the cport as you like: + + + +cport = my_own_control_port; +]]> + + + + + + The 6th argument specifies the irq number for UART. If the irq + is already allocated, pass 0 to the 7th argument + (irq_flags). Otherwise, pass the flags + for irq allocation + (SA_XXX bits) to it, and the irq will be + reserved by the mpu401-uart layer. If the card doesn't generate + UART interrupts, pass -1 as the irq number. Then a timer + interrupt will be invoked for polling. + +
+ +
+ Interrupt Handler + + When the interrupt is allocated in + snd_mpu401_uart_new(), the private + interrupt handler is used, hence you don't have anything else to do + than creating the mpu401 stuff. Otherwise, you have to call + snd_mpu401_uart_interrupt() explicitly when + a UART interrupt is invoked and checked in your own interrupt + handler. + + + + In this case, you need to pass the private_data of the + returned rawmidi object from + snd_mpu401_uart_new() as the second + argument of snd_mpu401_uart_interrupt(). + + + +private_data, regs); +]]> + + + +
+ + + + + + + + + RawMIDI Interface + +
+ Overview + + + The raw MIDI interface is used for hardware MIDI ports that can + be accessed as a byte stream. It is not used for synthesizer + chips that do not directly understand MIDI. + + + + ALSA handles file and buffer management. All you have to do is + to write some code to move data between the buffer and the + hardware. + + + + The rawmidi API is defined in + <sound/rawmidi.h>. + +
+ +
+ Constructor + + + To create a rawmidi device, call the + snd_rawmidi_new function: + + +card, "MyMIDI", 0, outs, ins, &rmidi); + if (err < 0) + return err; + rmidi->private_data = chip; + strcpy(rmidi->name, "My MIDI"); + rmidi->info_flags = SNDRV_RAWMIDI_INFO_OUTPUT | + SNDRV_RAWMIDI_INFO_INPUT | + SNDRV_RAWMIDI_INFO_DUPLEX; +]]> + + + + + + The first argument is the card pointer, the second argument is + the ID string. + + + + The third argument is the index of this component. You can + create up to 8 rawmidi devices. + + + + The fourth and fifth arguments are the number of output and + input substreams, respectively, of this device (a substream is + the equivalent of a MIDI port). + + + + Set the info_flags field to specify + the capabilities of the device. + Set SNDRV_RAWMIDI_INFO_OUTPUT if there is + at least one output port, + SNDRV_RAWMIDI_INFO_INPUT if there is at + least one input port, + and SNDRV_RAWMIDI_INFO_DUPLEX if the device + can handle output and input at the same time. + + + + After the rawmidi device is created, you need to set the + operators (callbacks) for each substream. There are helper + functions to set the operators for all the substreams of a device: + + + + + + + + + The operators are usually defined like this: + + + + + + These callbacks are explained in the Callbacks + section. + + + + If there are more than one substream, you should give a + unique name to each of them: + + +streams[SNDRV_RAWMIDI_STREAM_OUTPUT].substreams, + list { + sprintf(substream->name, "My MIDI Port %d", substream->number + 1); + } + /* same for SNDRV_RAWMIDI_STREAM_INPUT */ +]]> + + + +
+ +
+ Callbacks + + + In all the callbacks, the private data that you've set for the + rawmidi device can be accessed as + substream->rmidi->private_data. + + + + + If there is more than one port, your callbacks can determine the + port index from the struct snd_rawmidi_substream data passed to each + callback: + + +number; +]]> + + + + +
+ <function>open</function> callback + + + + + + + + + This is called when a substream is opened. + You can initialize the hardware here, but you shouldn't + start transmitting/receiving data yet. + +
+ +
+ <function>close</function> callback + + + + + + + + + Guess what. + + + + The open and close + callbacks of a rawmidi device are serialized with a mutex, + and can sleep. + +
+ +
+ <function>trigger</function> callback for output + substreams + + + + + + + + + This is called with a nonzero up + parameter when there is some data in the substream buffer that + must be transmitted. + + + + To read data from the buffer, call + snd_rawmidi_transmit_peek. It will + return the number of bytes that have been read; this will be + less than the number of bytes requested when there are no more + data in the buffer. + After the data have been transmitted successfully, call + snd_rawmidi_transmit_ack to remove the + data from the substream buffer: + + + + + + + + + If you know beforehand that the hardware will accept data, you + can use the snd_rawmidi_transmit function + which reads some data and removes them from the buffer at once: + + + + + + + + + If you know beforehand how many bytes you can accept, you can + use a buffer size greater than one with the + snd_rawmidi_transmit* functions. + + + + The trigger callback must not sleep. If + the hardware FIFO is full before the substream buffer has been + emptied, you have to continue transmitting data later, either + in an interrupt handler, or with a timer if the hardware + doesn't have a MIDI transmit interrupt. + + + + The trigger callback is called with a + zero up parameter when the transmission + of data should be aborted. + +
+ +
+ <function>trigger</function> callback for input + substreams + + + + + + + + + This is called with a nonzero up + parameter to enable receiving data, or with a zero + up parameter do disable receiving data. + + + + The trigger callback must not sleep; the + actual reading of data from the device is usually done in an + interrupt handler. + + + + When data reception is enabled, your interrupt handler should + call snd_rawmidi_receive for all received + data: + + + + + + +
+ +
+ <function>drain</function> callback + + + + + + + + + This is only used with output substreams. This function should wait + until all data read from the substream buffer have been transmitted. + This ensures that the device can be closed and the driver unloaded + without losing data. + + + + This callback is optional. If you do not set + drain in the struct snd_rawmidi_ops + structure, ALSA will simply wait for 50 milliseconds + instead. + +
+
+ + + + + + + + + Miscellaneous Devices + +
+ FM OPL3 + + The FM OPL3 is still used in many chips (mainly for backward + compatibility). ALSA has a nice OPL3 FM control layer, too. The + OPL3 API is defined in + <sound/opl3.h>. + + + + FM registers can be directly accessed through the direct-FM API, + defined in <sound/asound_fm.h>. In + ALSA native mode, FM registers are accessed through + the Hardware-Dependant Device direct-FM extension API, whereas in + OSS compatible mode, FM registers can be accessed with the OSS + direct-FM compatible API in /dev/dmfmX device. + + + + To create the OPL3 component, you have two functions to + call. The first one is a constructor for the opl3_t + instance. + + + + + + + + + + The first argument is the card pointer, the second one is the + left port address, and the third is the right port address. In + most cases, the right port is placed at the left port + 2. + + + + The fourth argument is the hardware type. + + + + When the left and right ports have been already allocated by + the card driver, pass non-zero to the fifth argument + (integrated). Otherwise, the opl3 module will + allocate the specified ports by itself. + + + + When the accessing the hardware requires special method + instead of the standard I/O access, you can create opl3 instance + separately with snd_opl3_new(). + + + + + + + + + + Then set command, + private_data and + private_free for the private + access function, the private data and the destructor. + The l_port and r_port are not necessarily set. Only the + command must be set properly. You can retrieve the data + from the opl3->private_data field. + + + + After creating the opl3 instance via snd_opl3_new(), + call snd_opl3_init() to initialize the chip to the + proper state. Note that snd_opl3_create() always + calls it internally. + + + + If the opl3 instance is created successfully, then create a + hwdep device for this opl3. + + + + + + + + + + The first argument is the opl3_t instance you + created, and the second is the index number, usually 0. + + + + The third argument is the index-offset for the sequencer + client assigned to the OPL3 port. When there is an MPU401-UART, + give 1 for here (UART always takes 0). + +
+ +
+ Hardware-Dependent Devices + + Some chips need user-space access for special + controls or for loading the micro code. In such a case, you can + create a hwdep (hardware-dependent) device. The hwdep API is + defined in <sound/hwdep.h>. You can + find examples in opl3 driver or + isa/sb/sb16_csp.c. + + + + The creation of the hwdep instance is done via + snd_hwdep_new(). + + + + + + + + where the third argument is the index number. + + + + You can then pass any pointer value to the + private_data. + If you assign a private data, you should define the + destructor, too. The destructor function is set in + the private_free field. + + + +private_data = p; + hw->private_free = mydata_free; +]]> + + + + and the implementation of the destructor would be: + + + +private_data; + kfree(p); + } +]]> + + + + + + The arbitrary file operations can be defined for this + instance. The file operators are defined in + the ops table. For example, assume that + this chip needs an ioctl. + + + +ops.open = mydata_open; + hw->ops.ioctl = mydata_ioctl; + hw->ops.release = mydata_release; +]]> + + + + And implement the callback functions as you like. + +
+ +
+ IEC958 (S/PDIF) + + Usually the controls for IEC958 devices are implemented via + the control interface. There is a macro to compose a name string for + IEC958 controls, SNDRV_CTL_NAME_IEC958() + defined in <include/asound.h>. + + + + There are some standard controls for IEC958 status bits. These + controls use the type SNDRV_CTL_ELEM_TYPE_IEC958, + and the size of element is fixed as 4 bytes array + (value.iec958.status[x]). For the info + callback, you don't specify + the value field for this type (the count field must be set, + though). + + + + IEC958 Playback Con Mask is used to return the + bit-mask for the IEC958 status bits of consumer mode. Similarly, + IEC958 Playback Pro Mask returns the bitmask for + professional mode. They are read-only controls, and are defined + as MIXER controls (iface = + SNDRV_CTL_ELEM_IFACE_MIXER). + + + + Meanwhile, IEC958 Playback Default control is + defined for getting and setting the current default IEC958 + bits. Note that this one is usually defined as a PCM control + (iface = SNDRV_CTL_ELEM_IFACE_PCM), + although in some places it's defined as a MIXER control. + + + + In addition, you can define the control switches to + enable/disable or to set the raw bit mode. The implementation + will depend on the chip, but the control should be named as + IEC958 xxx, preferably using + the SNDRV_CTL_NAME_IEC958() macro. + + + + You can find several cases, for example, + pci/emu10k1, + pci/ice1712, or + pci/cmipci.c. + +
+ + + + + + + + + Buffer and Memory Management + +
+ Buffer Types + + ALSA provides several different buffer allocation functions + depending on the bus and the architecture. All these have a + consistent API. The allocation of physically-contiguous pages is + done via + snd_malloc_xxx_pages() function, where xxx + is the bus type. + + + + The allocation of pages with fallback is + snd_malloc_xxx_pages_fallback(). This + function tries to allocate the specified pages but if the pages + are not available, it tries to reduce the page sizes until + enough space is found. + + + + The release the pages, call + snd_free_xxx_pages() function. + + + + Usually, ALSA drivers try to allocate and reserve + a large contiguous physical space + at the time the module is loaded for the later use. + This is called pre-allocation. + As already written, you can call the following function at + pcm instance construction time (in the case of PCI bus). + + + + + + + + where size is the byte size to be + pre-allocated and the max is the maximum + size to be changed via the prealloc proc file. + The allocator will try to get an area as large as possible + within the given size. + + + + The second argument (type) and the third argument (device pointer) + are dependent on the bus. + In the case of the ISA bus, pass snd_dma_isa_data() + as the third argument with SNDRV_DMA_TYPE_DEV type. + For the continuous buffer unrelated to the bus can be pre-allocated + with SNDRV_DMA_TYPE_CONTINUOUS type and the + snd_dma_continuous_data(GFP_KERNEL) device pointer, + where GFP_KERNEL is the kernel allocation flag to + use. + For the PCI scatter-gather buffers, use + SNDRV_DMA_TYPE_DEV_SG with + snd_dma_pci_data(pci) + (see the + Non-Contiguous Buffers + section). + + + + Once the buffer is pre-allocated, you can use the + allocator in the hw_params callback: + + + + + + + + Note that you have to pre-allocate to use this function. + +
+ +
+ External Hardware Buffers + + Some chips have their own hardware buffers and the DMA + transfer from the host memory is not available. In such a case, + you need to either 1) copy/set the audio data directly to the + external hardware buffer, or 2) make an intermediate buffer and + copy/set the data from it to the external hardware buffer in + interrupts (or in tasklets, preferably). + + + + The first case works fine if the external hardware buffer is large + enough. This method doesn't need any extra buffers and thus is + more effective. You need to define the + copy and + silence callbacks for + the data transfer. However, there is a drawback: it cannot + be mmapped. The examples are GUS's GF1 PCM or emu8000's + wavetable PCM. + + + + The second case allows for mmap on the buffer, although you have + to handle an interrupt or a tasklet to transfer the data + from the intermediate buffer to the hardware buffer. You can find an + example in the vxpocket driver. + + + + Another case is when the chip uses a PCI memory-map + region for the buffer instead of the host memory. In this case, + mmap is available only on certain architectures like the Intel one. + In non-mmap mode, the data cannot be transferred as in the normal + way. Thus you need to define the copy and + silence callbacks as well, + as in the cases above. The examples are found in + rme32.c and rme96.c. + + + + The implementation of the copy and + silence callbacks depends upon + whether the hardware supports interleaved or non-interleaved + samples. The copy callback is + defined like below, a bit + differently depending whether the direction is playback or + capture: + + + + + + + + + + In the case of interleaved samples, the second argument + (channel) is not used. The third argument + (pos) points the + current position offset in frames. + + + + The meaning of the fourth argument is different between + playback and capture. For playback, it holds the source data + pointer, and for capture, it's the destination data pointer. + + + + The last argument is the number of frames to be copied. + + + + What you have to do in this callback is again different + between playback and capture directions. In the + playback case, you copy the given amount of data + (count) at the specified pointer + (src) to the specified offset + (pos) on the hardware buffer. When + coded like memcpy-like way, the copy would be like: + + + + + + + + + + For the capture direction, you copy the given amount of + data (count) at the specified offset + (pos) on the hardware buffer to the + specified pointer (dst). + + + + + + + + Note that both the position and the amount of data are given + in frames. + + + + In the case of non-interleaved samples, the implementation + will be a bit more complicated. + + + + You need to check the channel argument, and if it's -1, copy + the whole channels. Otherwise, you have to copy only the + specified channel. Please check + isa/gus/gus_pcm.c as an example. + + + + The silence callback is also + implemented in a similar way. + + + + + + + + + + The meanings of arguments are the same as in the + copy + callback, although there is no src/dst + argument. In the case of interleaved samples, the channel + argument has no meaning, as well as on + copy callback. + + + + The role of silence callback is to + set the given amount + (count) of silence data at the + specified offset (pos) on the hardware + buffer. Suppose that the data format is signed (that is, the + silent-data is 0), and the implementation using a memset-like + function would be like: + + + + + + + + + + In the case of non-interleaved samples, again, the + implementation becomes a bit more complicated. See, for example, + isa/gus/gus_pcm.c. + +
+ +
+ Non-Contiguous Buffers + + If your hardware supports the page table as in emu10k1 or the + buffer descriptors as in via82xx, you can use the scatter-gather + (SG) DMA. ALSA provides an interface for handling SG-buffers. + The API is provided in <sound/pcm.h>. + + + + For creating the SG-buffer handler, call + snd_pcm_lib_preallocate_pages() or + snd_pcm_lib_preallocate_pages_for_all() + with SNDRV_DMA_TYPE_DEV_SG + in the PCM constructor like other PCI pre-allocator. + You need to pass snd_dma_pci_data(pci), + where pci is the struct pci_dev pointer + of the chip as well. + The struct snd_sg_buf instance is created as + substream->dma_private. You can cast + the pointer like: + + + +dma_private; +]]> + + + + + + Then call snd_pcm_lib_malloc_pages() + in the hw_params callback + as well as in the case of normal PCI buffer. + The SG-buffer handler will allocate the non-contiguous kernel + pages of the given size and map them onto the virtually contiguous + memory. The virtual pointer is addressed in runtime->dma_area. + The physical address (runtime->dma_addr) is set to zero, + because the buffer is physically non-contigous. + The physical address table is set up in sgbuf->table. + You can get the physical address at a certain offset via + snd_pcm_sgbuf_get_addr(). + + + + When a SG-handler is used, you need to set + snd_pcm_sgbuf_ops_page as + the page callback. + (See + page callback section.) + + + + To release the data, call + snd_pcm_lib_free_pages() in the + hw_free callback as usual. + +
+ +
+ Vmalloc'ed Buffers + + It's possible to use a buffer allocated via + vmalloc, for example, for an intermediate + buffer. Since the allocated pages are not contiguous, you need + to set the page callback to obtain + the physical address at every offset. + + + + The implementation of page callback + would be like this: + + + + + + /* get the physical page pointer on the given offset */ + static struct page *mychip_page(struct snd_pcm_substream *substream, + unsigned long offset) + { + void *pageptr = substream->runtime->dma_area + offset; + return vmalloc_to_page(pageptr); + } +]]> + + + +
+ + + + + + + + + Proc Interface + + ALSA provides an easy interface for procfs. The proc files are + very useful for debugging. I recommend you set up proc files if + you write a driver and want to get a running status or register + dumps. The API is found in + <sound/info.h>. + + + + To create a proc file, call + snd_card_proc_new(). + + + + + + + + where the second argument specifies the name of the proc file to be + created. The above example will create a file + my-file under the card directory, + e.g. /proc/asound/card0/my-file. + + + + Like other components, the proc entry created via + snd_card_proc_new() will be registered and + released automatically in the card registration and release + functions. + + + + When the creation is successful, the function stores a new + instance in the pointer given in the third argument. + It is initialized as a text proc file for read only. To use + this proc file as a read-only text file as it is, set the read + callback with a private data via + snd_info_set_text_ops(). + + + + + + + + where the second argument (chip) is the + private data to be used in the callbacks. The third parameter + specifies the read buffer size and the fourth + (my_proc_read) is the callback function, which + is defined like + + + + + + + + + + + In the read callback, use snd_iprintf() for + output strings, which works just like normal + printf(). For example, + + + +private_data; + + snd_iprintf(buffer, "This is my chip!\n"); + snd_iprintf(buffer, "Port = %ld\n", chip->port); + } +]]> + + + + + + The file permissions can be changed afterwards. As default, it's + set as read only for all users. If you want to add write + permission for the user (root as default), do as follows: + + + +mode = S_IFREG | S_IRUGO | S_IWUSR; +]]> + + + + and set the write buffer size and the callback + + + +c.text.write = my_proc_write; +]]> + + + + + + For the write callback, you can use + snd_info_get_line() to get a text line, and + snd_info_get_str() to retrieve a string from + the line. Some examples are found in + core/oss/mixer_oss.c, core/oss/and + pcm_oss.c. + + + + For a raw-data proc-file, set the attributes as follows: + + + +content = SNDRV_INFO_CONTENT_DATA; + entry->private_data = chip; + entry->c.ops = &my_file_io_ops; + entry->size = 4096; + entry->mode = S_IFREG | S_IRUGO; +]]> + + + + + + The callback is much more complicated than the text-file + version. You need to use a low-level I/O functions such as + copy_from/to_user() to transfer the + data. + + + + local_max_size) + size = local_max_size - pos; + if (copy_to_user(buf, local_data + pos, size)) + return -EFAULT; + return size; + } +]]> + + + + + + + + + + + + Power Management + + If the chip is supposed to work with suspend/resume + functions, you need to add power-management code to the + driver. The additional code for power-management should be + ifdef'ed with + CONFIG_PM. + + + + If the driver fully supports suspend/resume + that is, the device can be + properly resumed to its state when suspend was called, + you can set the SNDRV_PCM_INFO_RESUME flag + in the pcm info field. Usually, this is possible when the + registers of the chip can be safely saved and restored to + RAM. If this is set, the trigger callback is called with + SNDRV_PCM_TRIGGER_RESUME after the resume + callback completes. + + + + Even if the driver doesn't support PM fully but + partial suspend/resume is still possible, it's still worthy to + implement suspend/resume callbacks. In such a case, applications + would reset the status by calling + snd_pcm_prepare() and restart the stream + appropriately. Hence, you can define suspend/resume callbacks + below but don't set SNDRV_PCM_INFO_RESUME + info flag to the PCM. + + + + Note that the trigger with SUSPEND can always be called when + snd_pcm_suspend_all is called, + regardless of the SNDRV_PCM_INFO_RESUME flag. + The RESUME flag affects only the behavior + of snd_pcm_resume(). + (Thus, in theory, + SNDRV_PCM_TRIGGER_RESUME isn't needed + to be handled in the trigger callback when no + SNDRV_PCM_INFO_RESUME flag is set. But, + it's better to keep it for compatibility reasons.) + + + In the earlier version of ALSA drivers, a common + power-management layer was provided, but it has been removed. + The driver needs to define the suspend/resume hooks according to + the bus the device is connected to. In the case of PCI drivers, the + callbacks look like below: + + + + + + + + + + The scheme of the real suspend job is as follows. + + + Retrieve the card and the chip data. + Call snd_power_change_state() with + SNDRV_CTL_POWER_D3hot to change the + power status. + Call snd_pcm_suspend_all() to suspend the running PCM streams. + If AC97 codecs are used, call + snd_ac97_suspend() for each codec. + Save the register values if necessary. + Stop the hardware if necessary. + Disable the PCI device by calling + pci_disable_device(). Then, call + pci_save_state() at last. + + + + + A typical code would be like: + + + +private_data; + /* (2) */ + snd_power_change_state(card, SNDRV_CTL_POWER_D3hot); + /* (3) */ + snd_pcm_suspend_all(chip->pcm); + /* (4) */ + snd_ac97_suspend(chip->ac97); + /* (5) */ + snd_mychip_save_registers(chip); + /* (6) */ + snd_mychip_stop_hardware(chip); + /* (7) */ + pci_disable_device(pci); + pci_save_state(pci); + return 0; + } +]]> + + + + + + The scheme of the real resume job is as follows. + + + Retrieve the card and the chip data. + Set up PCI. First, call pci_restore_state(). + Then enable the pci device again by calling pci_enable_device(). + Call pci_set_master() if necessary, too. + Re-initialize the chip. + Restore the saved registers if necessary. + Resume the mixer, e.g. calling + snd_ac97_resume(). + Restart the hardware (if any). + Call snd_power_change_state() with + SNDRV_CTL_POWER_D0 to notify the processes. + + + + + A typical code would be like: + + + +private_data; + /* (2) */ + pci_restore_state(pci); + pci_enable_device(pci); + pci_set_master(pci); + /* (3) */ + snd_mychip_reinit_chip(chip); + /* (4) */ + snd_mychip_restore_registers(chip); + /* (5) */ + snd_ac97_resume(chip->ac97); + /* (6) */ + snd_mychip_restart_chip(chip); + /* (7) */ + snd_power_change_state(card, SNDRV_CTL_POWER_D0); + return 0; + } +]]> + + + + + + As shown in the above, it's better to save registers after + suspending the PCM operations via + snd_pcm_suspend_all() or + snd_pcm_suspend(). It means that the PCM + streams are already stoppped when the register snapshot is + taken. But, remember that you don't have to restart the PCM + stream in the resume callback. It'll be restarted via + trigger call with SNDRV_PCM_TRIGGER_RESUME + when necessary. + + + + OK, we have all callbacks now. Let's set them up. In the + initialization of the card, make sure that you can get the chip + data from the card instance, typically via + private_data field, in case you + created the chip data individually. + + + +private_data = chip; + .... + } +]]> + + + + When you created the chip data with + snd_card_create(), it's anyway accessible + via private_data field. + + + +private_data; + .... + } +]]> + + + + + + + If you need a space to save the registers, allocate the + buffer for it here, too, since it would be fatal + if you cannot allocate a memory in the suspend phase. + The allocated buffer should be released in the corresponding + destructor. + + + + And next, set suspend/resume callbacks to the pci_driver. + + + + + + + + + + + + + + + + Module Parameters + + There are standard module options for ALSA. At least, each + module should have the index, + id and enable + options. + + + + If the module supports multiple cards (usually up to + 8 = SNDRV_CARDS cards), they should be + arrays. The default initial values are defined already as + constants for easier programming: + + + + + + + + + + If the module supports only a single card, they could be single + variables, instead. enable option is not + always necessary in this case, but it would be better to have a + dummy option for compatibility. + + + + The module parameters must be declared with the standard + module_param()(), + module_param_array()() and + MODULE_PARM_DESC() macros. + + + + The typical coding would be like below: + + + + + + + + + + Also, don't forget to define the module description, classes, + license and devices. Especially, the recent modprobe requires to + define the module license as GPL, etc., otherwise the system is + shown as tainted. + + + + + + + + + + + + + + + + How To Put Your Driver Into ALSA Tree +
+ General + + So far, you've learned how to write the driver codes. + And you might have a question now: how to put my own + driver into the ALSA driver tree? + Here (finally :) the standard procedure is described briefly. + + + + Suppose that you create a new PCI driver for the card + xyz. The card module name would be + snd-xyz. The new driver is usually put into the alsa-driver + tree, alsa-driver/pci directory in + the case of PCI cards. + Then the driver is evaluated, audited and tested + by developers and users. After a certain time, the driver + will go to the alsa-kernel tree (to the corresponding directory, + such as alsa-kernel/pci) and eventually + will be integrated into the Linux 2.6 tree (the directory would be + linux/sound/pci). + + + + In the following sections, the driver code is supposed + to be put into alsa-driver tree. The two cases are covered: + a driver consisting of a single source file and one consisting + of several source files. + +
+ +
+ Driver with A Single Source File + + + + + Modify alsa-driver/pci/Makefile + + + + Suppose you have a file xyz.c. Add the following + two lines + + + + + + + + + + + Create the Kconfig entry + + + + Add the new entry of Kconfig for your xyz driver. + + + + + + + the line, select SND_PCM, specifies that the driver xyz supports + PCM. In addition to SND_PCM, the following components are + supported for select command: + SND_RAWMIDI, SND_TIMER, SND_HWDEP, SND_MPU401_UART, + SND_OPL3_LIB, SND_OPL4_LIB, SND_VX_LIB, SND_AC97_CODEC. + Add the select command for each supported component. + + + + Note that some selections imply the lowlevel selections. + For example, PCM includes TIMER, MPU401_UART includes RAWMIDI, + AC97_CODEC includes PCM, and OPL3_LIB includes HWDEP. + You don't need to give the lowlevel selections again. + + + + For the details of Kconfig script, refer to the kbuild + documentation. + + + + + + + Run cvscompile script to re-generate the configure script and + build the whole stuff again. + + + + +
+ +
+ Drivers with Several Source Files + + Suppose that the driver snd-xyz have several source files. + They are located in the new subdirectory, + pci/xyz. + + + + + Add a new directory (xyz) in + alsa-driver/pci/Makefile as below + + + + + + + + + + + + Under the directory xyz, create a Makefile + + + Sample Makefile for a driver xyz + + + + + + + + + + Create the Kconfig entry + + + + This procedure is as same as in the last section. + + + + + + Run cvscompile script to re-generate the configure script and + build the whole stuff again. + + + + +
+ + + + + + + + Useful Functions + +
+ <function>snd_printk()</function> and friends + + ALSA provides a verbose version of the + printk() function. If a kernel config + CONFIG_SND_VERBOSE_PRINTK is set, this + function prints the given message together with the file name + and the line of the caller. The KERN_XXX + prefix is processed as + well as the original printk() does, so it's + recommended to add this prefix, e.g. + + + + + + + + + + There are also printk()'s for + debugging. snd_printd() can be used for + general debugging purposes. If + CONFIG_SND_DEBUG is set, this function is + compiled, and works just like + snd_printk(). If the ALSA is compiled + without the debugging flag, it's ignored. + + + + snd_printdd() is compiled in only when + CONFIG_SND_DEBUG_VERBOSE is set. Please note + that CONFIG_SND_DEBUG_VERBOSE is not set as default + even if you configure the alsa-driver with + option. You need to give + explicitly option instead. + +
+ +
+ <function>snd_BUG()</function> + + It shows the BUG? message and + stack trace as well as snd_BUG_ON at the point. + It's useful to show that a fatal error happens there. + + + When no debug flag is set, this macro is ignored. + +
+ +
+ <function>snd_BUG_ON()</function> + + snd_BUG_ON() macro is similar with + WARN_ON() macro. For example, + + + + + + + + or it can be used as the condition, + + + + + + + + + + The macro takes an conditional expression to evaluate. + When CONFIG_SND_DEBUG, is set, the + expression is actually evaluated. If it's non-zero, it shows + the warning message such as + BUG? (xxx) + normally followed by stack trace. It returns the evaluated + value. + When no CONFIG_SND_DEBUG is set, this + macro always returns zero. + + +

The document focuses mainly on PCI soundcards. - In the case of other device types, the API might - be different, too. However, at least the ALSA kernel API is - consistent, and therefore it would be still a bit help for - writing them. - - - - This document targets people who already have enough - C language skills and have basic linux kernel programming - knowledge. This document doesn't explain the general - topic of linux kernel coding and doesn't cover low-level - driver implementation details. It only describes - the standard way to write a PCI sound driver on ALSA. - - - - If you are already familiar with the older ALSA ver.0.5.x API, you - can check the drivers such as sound/pci/es1938.c or - sound/pci/maestro3.c which have also almost the same - code-base in the ALSA 0.5.x tree, so you can compare the differences. - - - - This document is still a draft version. Any feedback and - corrections, please!! - - - - - - - - - File Tree Structure - -
- General - - The ALSA drivers are provided in two ways. - - - - One is the trees provided as a tarball or via cvs from the - ALSA's ftp site, and another is the 2.6 (or later) Linux kernel - tree. To synchronize both, the ALSA driver tree is split into - two different trees: alsa-kernel and alsa-driver. The former - contains purely the source code for the Linux 2.6 (or later) - tree. This tree is designed only for compilation on 2.6 or - later environment. The latter, alsa-driver, contains many subtle - files for compiling ALSA drivers outside of the Linux kernel tree, - wrapper functions for older 2.2 and 2.4 kernels, to adapt the latest kernel API, - and additional drivers which are still in development or in - tests. The drivers in alsa-driver tree will be moved to - alsa-kernel (and eventually to the 2.6 kernel tree) when they are - finished and confirmed to work fine. - - - - The file tree structure of ALSA driver is depicted below. Both - alsa-kernel and alsa-driver have almost the same file - structure, except for core directory. It's - named as acore in alsa-driver tree. - - - ALSA File Tree Structure - - sound - /core - /oss - /seq - /oss - /instr - /ioctl32 - /include - /drivers - /mpu401 - /opl3 - /i2c - /l3 - /synth - /emux - /pci - /(cards) - /isa - /(cards) - /arm - /ppc - /sparc - /usb - /pcmcia /(cards) - /oss - - - -
- -
- core directory - - This directory contains the middle layer which is the heart - of ALSA drivers. In this directory, the native ALSA modules are - stored. The sub-directories contain different modules and are - dependent upon the kernel config. - - -
- core/oss - - - The codes for PCM and mixer OSS emulation modules are stored - in this directory. The rawmidi OSS emulation is included in - the ALSA rawmidi code since it's quite small. The sequencer - code is stored in core/seq/oss directory (see - - below). - -
- -
- core/ioctl32 - - - This directory contains the 32bit-ioctl wrappers for 64bit - architectures such like x86-64, ppc64 and sparc64. For 32bit - and alpha architectures, these are not compiled. - -
- -
- core/seq - - This directory and its sub-directories are for the ALSA - sequencer. This directory contains the sequencer core and - primary sequencer modules such like snd-seq-midi, - snd-seq-virmidi, etc. They are compiled only when - CONFIG_SND_SEQUENCER is set in the kernel - config. - -
- -
- core/seq/oss - - This contains the OSS sequencer emulation codes. - -
- -
- core/seq/instr - - This directory contains the modules for the sequencer - instrument layer. - -
-
- -
- include directory - - This is the place for the public header files of ALSA drivers, - which are to be exported to user-space, or included by - several files at different directories. Basically, the private - header files should not be placed in this directory, but you may - still find files there, due to historical reasons :) - -
- -
- drivers directory - - This directory contains code shared among different drivers - on different architectures. They are hence supposed not to be - architecture-specific. - For example, the dummy pcm driver and the serial MIDI - driver are found in this directory. In the sub-directories, - there is code for components which are independent from - bus and cpu architectures. - - -
- drivers/mpu401 - - The MPU401 and MPU401-UART modules are stored here. - -
- -
- drivers/opl3 and opl4 - - The OPL3 and OPL4 FM-synth stuff is found here. - -
-
- -
- i2c directory - - This contains the ALSA i2c components. - - - - Although there is a standard i2c layer on Linux, ALSA has its - own i2c code for some cards, because the soundcard needs only a - simple operation and the standard i2c API is too complicated for - such a purpose. - - -
- i2c/l3 - - This is a sub-directory for ARM L3 i2c. - -
-
- -
- synth directory - - This contains the synth middle-level modules. - - - - So far, there is only Emu8000/Emu10k1 synth driver under - the synth/emux sub-directory. - -
- -
- pci directory - - This directory and its sub-directories hold the top-level card modules - for PCI soundcards and the code specific to the PCI BUS. - - - - The drivers compiled from a single file are stored directly - in the pci directory, while the drivers with several source files are - stored on their own sub-directory (e.g. emu10k1, ice1712). - -
- -
- isa directory - - This directory and its sub-directories hold the top-level card modules - for ISA soundcards. - -
- -
- arm, ppc, and sparc directories - - They are used for top-level card modules which are - specific to one of these architectures. - -
- -
- usb directory - - This directory contains the USB-audio driver. In the latest version, the - USB MIDI driver is integrated in the usb-audio driver. - -
- -
- pcmcia directory - - The PCMCIA, especially PCCard drivers will go here. CardBus - drivers will be in the pci directory, because their API is identical - to that of standard PCI cards. - -
- -
- oss directory - - The OSS/Lite source files are stored here in Linux 2.6 (or - later) tree. In the ALSA driver tarball, this directory is empty, - of course :) - -
- - - - - - - - Basic Flow for PCI Drivers - -
- Outline - - The minimum flow for PCI soundcards is as follows: - - - define the PCI ID table (see the section - PCI Entries - ). - create probe() callback. - create remove() callback. - create a pci_driver structure - containing the three pointers above. - create an init() function just calling - the pci_register_driver() to register the pci_driver table - defined above. - create an exit() function to call - the pci_unregister_driver() function. - - -
- -
- Full Code Example - - The code example is shown below. Some parts are kept - unimplemented at this moment but will be filled in the - next sections. The numbers in the comment lines of the - snd_mychip_probe() function - refer to details explained in the following section. - - - Basic Flow for PCI Drivers - Example - - - #include - #include - #include - #include - - /* module parameters (see "Module Parameters") */ - /* SNDRV_CARDS: maximum number of cards supported by this module */ - static int index[SNDRV_CARDS] = SNDRV_DEFAULT_IDX; - static char *id[SNDRV_CARDS] = SNDRV_DEFAULT_STR; - static int enable[SNDRV_CARDS] = SNDRV_DEFAULT_ENABLE_PNP; - - /* definition of the chip-specific record */ - struct mychip { - struct snd_card *card; - /* the rest of the implementation will be in section - * "PCI Resource Management" - */ - }; - - /* chip-specific destructor - * (see "PCI Resource Management") - */ - static int snd_mychip_free(struct mychip *chip) - { - .... /* will be implemented later... */ - } - - /* component-destructor - * (see "Management of Cards and Components") - */ - static int snd_mychip_dev_free(struct snd_device *device) - { - return snd_mychip_free(device->device_data); - } - - /* chip-specific constructor - * (see "Management of Cards and Components") - */ - static int __devinit snd_mychip_create(struct snd_card *card, - struct pci_dev *pci, - struct mychip **rchip) - { - struct mychip *chip; - int err; - static struct snd_device_ops ops = { - .dev_free = snd_mychip_dev_free, - }; - - *rchip = NULL; - - /* check PCI availability here - * (see "PCI Resource Management") - */ - .... - - /* allocate a chip-specific data with zero filled */ - chip = kzalloc(sizeof(*chip), GFP_KERNEL); - if (chip == NULL) - return -ENOMEM; - - chip->card = card; - - /* rest of initialization here; will be implemented - * later, see "PCI Resource Management" - */ - .... - - err = snd_device_new(card, SNDRV_DEV_LOWLEVEL, chip, &ops); - if (err < 0) { - snd_mychip_free(chip); - return err; - } - - snd_card_set_dev(card, &pci->dev); - - *rchip = chip; - return 0; - } - - /* constructor -- see "Constructor" sub-section */ - static int __devinit snd_mychip_probe(struct pci_dev *pci, - const struct pci_device_id *pci_id) - { - static int dev; - struct snd_card *card; - struct mychip *chip; - int err; - - /* (1) */ - if (dev >= SNDRV_CARDS) - return -ENODEV; - if (!enable[dev]) { - dev++; - return -ENOENT; - } - - /* (2) */ - err = snd_card_create(index[dev], id[dev], THIS_MODULE, 0, &card); - if (err < 0) - return err; - - /* (3) */ - err = snd_mychip_create(card, pci, &chip); - if (err < 0) { - snd_card_free(card); - return err; - } - - /* (4) */ - strcpy(card->driver, "My Chip"); - strcpy(card->shortname, "My Own Chip 123"); - sprintf(card->longname, "%s at 0x%lx irq %i", - card->shortname, chip->ioport, chip->irq); - - /* (5) */ - .... /* implemented later */ - - /* (6) */ - err = snd_card_register(card); - if (err < 0) { - snd_card_free(card); - return err; - } - - /* (7) */ - pci_set_drvdata(pci, card); - dev++; - return 0; - } - - /* destructor -- see the "Destructor" sub-section */ - static void __devexit snd_mychip_remove(struct pci_dev *pci) - { - snd_card_free(pci_get_drvdata(pci)); - pci_set_drvdata(pci, NULL); - } -]]> - - - -
- -
- Constructor - - The real constructor of PCI drivers is the probe callback. - The probe callback and other component-constructors which are called - from the probe callback should be defined with - the __devinit prefix. You - cannot use the __init prefix for them, - because any PCI device could be a hotplug device. - - - - In the probe callback, the following scheme is often used. - - -
- 1) Check and increment the device index. - - - -= SNDRV_CARDS) - return -ENODEV; - if (!enable[dev]) { - dev++; - return -ENOENT; - } -]]> - - - - where enable[dev] is the module option. - - - - Each time the probe callback is called, check the - availability of the device. If not available, simply increment - the device index and returns. dev will be incremented also - later (step - 7). - -
- -
- 2) Create a card instance - - - - - - - - - - The details will be explained in the section - - Management of Cards and Components. - -
- -
- 3) Create a main component - - In this part, the PCI resources are allocated. - - - - - - - - The details will be explained in the section PCI Resource - Management. - -
- -
- 4) Set the driver ID and name strings. - - - -driver, "My Chip"); - strcpy(card->shortname, "My Own Chip 123"); - sprintf(card->longname, "%s at 0x%lx irq %i", - card->shortname, chip->ioport, chip->irq); -]]> - - - - The driver field holds the minimal ID string of the - chip. This is used by alsa-lib's configurator, so keep it - simple but unique. - Even the same driver can have different driver IDs to - distinguish the functionality of each chip type. - - - - The shortname field is a string shown as more verbose - name. The longname field contains the information - shown in /proc/asound/cards. - -
- -
- 5) Create other components, such as mixer, MIDI, etc. - - Here you define the basic components such as - PCM, - mixer (e.g. AC97), - MIDI (e.g. MPU-401), - and other interfaces. - Also, if you want a proc - file, define it here, too. - -
- -
- 6) Register the card instance. - - - - - - - - - - Will be explained in the section Management - of Cards and Components, too. - -
- -
- 7) Set the PCI driver data and return zero. - - - - - - - - In the above, the card record is stored. This pointer is - used in the remove callback and power-management - callbacks, too. - -
-
- -
- Destructor - - The destructor, remove callback, simply releases the card - instance. Then the ALSA middle layer will release all the - attached components automatically. - - - - It would be typically like the following: - - - - - - - - The above code assumes that the card pointer is set to the PCI - driver data. - -
- -
- Header Files - - For the above example, at least the following include files - are necessary. - - - - - #include - #include - #include - #include -]]> - - - - where the last one is necessary only when module options are - defined in the source file. If the code is split into several - files, the files without module options don't need them. - - - - In addition to these headers, you'll need - <linux/interrupt.h> for interrupt - handling, and <asm/io.h> for I/O - access. If you use the mdelay() or - udelay() functions, you'll need to include - <linux/delay.h> too. - - - - The ALSA interfaces like the PCM and control APIs are defined in other - <sound/xxx.h> header files. - They have to be included after - <sound/core.h>. - - -
- - - - - - - - Management of Cards and Components - -
- Card Instance - - For each soundcard, a card record must be allocated. - - - - A card record is the headquarters of the soundcard. It manages - the whole list of devices (components) on the soundcard, such as - PCM, mixers, MIDI, synthesizer, and so on. Also, the card - record holds the ID and the name strings of the card, manages - the root of proc files, and controls the power-management states - and hotplug disconnections. The component list on the card - record is used to manage the correct release of resources at - destruction. - - - - As mentioned above, to create a card instance, call - snd_card_create(). - - - - - - - - - - The function takes five arguments, the card-index number, the - id string, the module pointer (usually - THIS_MODULE), - the size of extra-data space, and the pointer to return the - card instance. The extra_size argument is used to - allocate card->private_data for the - chip-specific data. Note that these data - are allocated by snd_card_create(). - -
- -
- Components - - After the card is created, you can attach the components - (devices) to the card instance. In an ALSA driver, a component is - represented as a struct snd_device object. - A component can be a PCM instance, a control interface, a raw - MIDI interface, etc. Each such instance has one component - entry. - - - - A component can be created via - snd_device_new() function. - - - - - - - - - - This takes the card pointer, the device-level - (SNDRV_DEV_XXX), the data pointer, and the - callback pointers (&ops). The - device-level defines the type of components and the order of - registration and de-registration. For most components, the - device-level is already defined. For a user-defined component, - you can use SNDRV_DEV_LOWLEVEL. - - - - This function itself doesn't allocate the data space. The data - must be allocated manually beforehand, and its pointer is passed - as the argument. This pointer is used as the - (chip identifier in the above example) - for the instance. - - - - Each pre-defined ALSA component such as ac97 and pcm calls - snd_device_new() inside its - constructor. The destructor for each component is defined in the - callback pointers. Hence, you don't need to take care of - calling a destructor for such a component. - - - - If you wish to create your own component, you need to - set the destructor function to the dev_free callback in - the ops, so that it can be released - automatically via snd_card_free(). - The next example will show an implementation of chip-specific - data. - -
- -
- Chip-Specific Data - - Chip-specific information, e.g. the I/O port address, its - resource pointer, or the irq number, is stored in the - chip-specific record. - - - - - - - - - - In general, there are two ways of allocating the chip record. - - -

Allocating via <function>snd_card_create()</function>. - - As mentioned above, you can pass the extra-data-length - to the 4th argument of snd_card_create(), i.e. - - - - - - - - struct mychip is the type of the chip record. - - - - In return, the allocated record can be accessed as - - - -private_data; -]]> - - - - With this method, you don't have to allocate twice. - The record is released together with the card instance. - -
- -
- 2. Allocating an extra device. - - - After allocating a card instance via - snd_card_create() (with - 0 on the 4th arg), call - kzalloc(). - - - - - - - - - - The chip record should have the field to hold the card - pointer at least, - - - - - - - - - - Then, set the card pointer in the returned chip instance. - - - -card = card; -]]> - - - - - - Next, initialize the fields, and register this chip - record as a low-level device with a specified - ops, - - - - - - - - snd_mychip_dev_free() is the - device-destructor function, which will call the real - destructor. - - - - - -device_data); - } -]]> - - - - where snd_mychip_free() is the real destructor. - -
-
- -
- Registration and Release - - After all components are assigned, register the card instance - by calling snd_card_register(). Access - to the device files is enabled at this point. That is, before - snd_card_register() is called, the - components are safely inaccessible from external side. If this - call fails, exit the probe function after releasing the card via - snd_card_free(). - - - - For releasing the card instance, you can call simply - snd_card_free(). As mentioned earlier, all - components are released automatically by this call. - - - - As further notes, the destructors (both - snd_mychip_dev_free and - snd_mychip_free) cannot be defined with - the __devexit prefix, because they may be - called from the constructor, too, at the false path. - - - - For a device which allows hotplugging, you can use - snd_card_free_when_closed. This one will - postpone the destruction until all devices are closed. - - -

- Some Hafta's - - The allocation of PCI resources is done in the - probe() function, and usually an extra - xxx_create() function is written for this - purpose. - - - - In the case of PCI devices, you first have to call - the pci_enable_device() function before - allocating resources. Also, you need to set the proper PCI DMA - mask to limit the accessed I/O range. In some cases, you might - need to call pci_set_master() function, - too. - - - - Suppose the 28bit mask, and the code to be added would be like: - - - - - - - -
- -
- Resource Allocation - - The allocation of I/O ports and irqs is done via standard kernel - functions. Unlike ALSA ver.0.5.x., there are no helpers for - that. And these resources must be released in the destructor - function (see below). Also, on ALSA 0.9.x, you don't need to - allocate (pseudo-)DMA for PCI like in ALSA 0.5.x. - - - - Now assume that the PCI device has an I/O port with 8 bytes - and an interrupt. Then struct mychip will have the - following fields: - - - - - - - - - - For an I/O port (and also a memory region), you need to have - the resource pointer for the standard resource management. For - an irq, you have to keep only the irq number (integer). But you - need to initialize this number as -1 before actual allocation, - since irq 0 is valid. The port address and its resource pointer - can be initialized as null by - kzalloc() automatically, so you - don't have to take care of resetting them. - - - - The allocation of an I/O port is done like this: - - - -port = pci_resource_start(pci, 0); -]]> - - - - - - - It will reserve the I/O port region of 8 bytes of the given - PCI device. The returned value, chip->res_port, is allocated - via kmalloc() by - request_region(). The pointer must be - released via kfree(), but there is a - problem with this. This issue will be explained later. - - - - The allocation of an interrupt source is done like this: - - - -irq, snd_mychip_interrupt, - IRQF_SHARED, "My Chip", chip)) { - printk(KERN_ERR "cannot grab irq %d\n", pci->irq); - snd_mychip_free(chip); - return -EBUSY; - } - chip->irq = pci->irq; -]]> - - - - where snd_mychip_interrupt() is the - interrupt handler defined later. - Note that chip->irq should be defined - only when request_irq() succeeded. - - - - On the PCI bus, interrupts can be shared. Thus, - IRQF_SHARED is used as the interrupt flag of - request_irq(). - - - - The last argument of request_irq() is the - data pointer passed to the interrupt handler. Usually, the - chip-specific record is used for that, but you can use what you - like, too. - - - - I won't give details about the interrupt handler at this - point, but at least its appearance can be explained now. The - interrupt handler looks usually like the following: - - - - - - - - - - Now let's write the corresponding destructor for the resources - above. The role of destructor is simple: disable the hardware - (if already activated) and release the resources. So far, we - have no hardware part, so the disabling code is not written here. - - - - To release the resources, the check-and-release - method is a safer way. For the interrupt, do like this: - - - -irq >= 0) - free_irq(chip->irq, chip); -]]> - - - - Since the irq number can start from 0, you should initialize - chip->irq with a negative value (e.g. -1), so that you can - check the validity of the irq number as above. - - - - When you requested I/O ports or memory regions via - pci_request_region() or - pci_request_regions() like in this example, - release the resource(s) using the corresponding function, - pci_release_region() or - pci_release_regions(). - - - -pci); -]]> - - - - - - When you requested manually via request_region() - or request_mem_region, you can release it via - release_resource(). Suppose that you keep - the resource pointer returned from request_region() - in chip->res_port, the release procedure looks like: - - - -res_port); -]]> - - - - - - Don't forget to call pci_disable_device() - before the end. - - - - And finally, release the chip-specific record. - - - - - - - - - - Again, remember that you cannot - use the __devexit prefix for this destructor. - - - - We didn't implement the hardware disabling part in the above. - If you need to do this, please note that the destructor may be - called even before the initialization of the chip is completed. - It would be better to have a flag to skip hardware disabling - if the hardware was not initialized yet. - - - - When the chip-data is assigned to the card using - snd_device_new() with - SNDRV_DEV_LOWLELVEL , its destructor is - called at the last. That is, it is assured that all other - components like PCMs and controls have already been released. - You don't have to stop PCMs, etc. explicitly, but just - call low-level hardware stopping. - - - - The management of a memory-mapped region is almost as same as - the management of an I/O port. You'll need three fields like - the following: - - - - - - - - and the allocation would be like below: - - - -iobase_phys = pci_resource_start(pci, 0); - chip->iobase_virt = ioremap_nocache(chip->iobase_phys, - pci_resource_len(pci, 0)); -]]> - - - - and the corresponding destructor would be: - - - -iobase_virt) - iounmap(chip->iobase_virt); - .... - pci_release_regions(chip->pci); - .... - } -]]> - - - - -
- -
- Registration of Device Struct - - At some point, typically after calling snd_device_new(), - you need to register the struct device of the chip - you're handling for udev and co. ALSA provides a macro for compatibility with - older kernels. Simply call like the following: - - -dev); -]]> - - - so that it stores the PCI's device pointer to the card. This will be - referred by ALSA core functions later when the devices are registered. - - - In the case of non-PCI, pass the proper device struct pointer of the BUS - instead. (In the case of legacy ISA without PnP, you don't have to do - anything.) - -
- -
- PCI Entries - - So far, so good. Let's finish the missing PCI - stuff. At first, we need a - pci_device_id table for this - chipset. It's a table of PCI vendor/device ID number, and some - masks. - - - - For example, - - - - - - - - - - The first and second fields of - the pci_device_id structure are the vendor and - device IDs. If you have no reason to filter the matching - devices, you can leave the remaining fields as above. The last - field of the pci_device_id struct contains - private data for this entry. You can specify any value here, for - example, to define specific operations for supported device IDs. - Such an example is found in the intel8x0 driver. - - - - The last entry of this list is the terminator. You must - specify this all-zero entry. - - - - Then, prepare the pci_driver record: - - - - - - - - - - The probe and - remove functions have already - been defined in the previous sections. - The remove function should - be defined with the - __devexit_p() macro, so that it's not - defined for built-in (and non-hot-pluggable) case. The - name - field is the name string of this device. Note that you must not - use a slash / in this string. - - - - And at last, the module entries: - - - - - - - - - - Note that these module entries are tagged with - __init and - __exit prefixes, not - __devinit nor - __devexit. - - - - Oh, one thing was forgotten. If you have no exported symbols, - you need to declare it in 2.2 or 2.4 kernels (it's not necessary in 2.6 kernels). - - - - - - - - That's all! - -
- - - - - - - - PCM Interface - -
- General - - The PCM middle layer of ALSA is quite powerful and it is only - necessary for each driver to implement the low-level functions - to access its hardware. - - - - For accessing to the PCM layer, you need to include - <sound/pcm.h> first. In addition, - <sound/pcm_params.h> might be needed - if you access to some functions related with hw_param. - - - - Each card device can have up to four pcm instances. A pcm - instance corresponds to a pcm device file. The limitation of - number of instances comes only from the available bit size of - the Linux's device numbers. Once when 64bit device number is - used, we'll have more pcm instances available. - - - - A pcm instance consists of pcm playback and capture streams, - and each pcm stream consists of one or more pcm substreams. Some - soundcards support multiple playback functions. For example, - emu10k1 has a PCM playback of 32 stereo substreams. In this case, at - each open, a free substream is (usually) automatically chosen - and opened. Meanwhile, when only one substream exists and it was - already opened, the successful open will either block - or error with EAGAIN according to the - file open mode. But you don't have to care about such details in your - driver. The PCM middle layer will take care of such work. - -

The first argument is the card pointer to which this - pcm is assigned, and the second is the ID string. - - - - The third argument (index, 0 in the - above) is the index of this new pcm. It begins from zero. If - you create more than one pcm instances, specify the - different numbers in this argument. For example, - index = 1 for the second PCM device. - - - - The fourth and fifth arguments are the number of substreams - for playback and capture, respectively. Here 1 is used for - both arguments. When no playback or capture substreams are available, - pass 0 to the corresponding argument. - - - - If a chip supports multiple playbacks or captures, you can - specify more numbers, but they must be handled properly in - open/close, etc. callbacks. When you need to know which - substream you are referring to, then it can be obtained from - struct snd_pcm_substream data passed to each callback - as follows: - - - -number; -]]> - - - - - - After the pcm is created, you need to set operators for each - pcm stream. - - - - - - - - - - The operators are defined typically like this: - - - - - - - - All the callbacks are described in the - - Operators subsection. - - - - After setting the operators, you probably will want to - pre-allocate the buffer. For the pre-allocation, simply call - the following: - - - -pci), - 64*1024, 64*1024); -]]> - - - - It will allocate a buffer up to 64kB as default. - Buffer management details will be described in the later section Buffer and Memory - Management. - - - - Additionally, you can set some extra information for this pcm - in pcm->info_flags. - The available values are defined as - SNDRV_PCM_INFO_XXX in - <sound/asound.h>, which is used for - the hardware definition (described later). When your soundchip - supports only half-duplex, specify like this: - - - -info_flags = SNDRV_PCM_INFO_HALF_DUPLEX; -]]> - - - -
- -
- ... And the Destructor? - - The destructor for a pcm instance is not always - necessary. Since the pcm device will be released by the middle - layer code automatically, you don't have to call the destructor - explicitly. - - - - The destructor would be necessary if you created - special records internally and needed to release them.

- Runtime Pointer - The Chest of PCM Information - - When the PCM substream is opened, a PCM runtime instance is - allocated and assigned to the substream. This pointer is - accessible via substream->runtime. - This runtime pointer holds most information you need - to control the PCM: the copy of hw_params and sw_params configurations, the buffer - pointers, mmap records, spinlocks, etc. - - - - The definition of runtime instance is found in - <sound/pcm.h>. Here are - the contents of this file: - - - - - - - - - For the operators (callbacks) of each sound driver, most of - these records are supposed to be read-only. Only the PCM - middle-layer changes / updates them. The exceptions are - the hardware description (hw), interrupt callbacks - (transfer_ack_xxx), DMA buffer information, and the private - data. Besides, if you use the standard buffer allocation - method via snd_pcm_lib_malloc_pages(), - you don't need to set the DMA buffer information by yourself. - - - - In the sections below, important records are explained. - - -
- Hardware Description - - The hardware descriptor (struct snd_pcm_hardware) - contains the definitions of the fundamental hardware - configuration. Above all, you'll need to define this in - - the open callback. - Note that the runtime instance holds the copy of the - descriptor, not the pointer to the existing descriptor. That - is, in the open callback, you can modify the copied descriptor - (runtime->hw) as you need. For example, if the maximum - number of channels is 1 only on some chip models, you can - still use the same hardware descriptor and change the - channels_max later: - - -runtime; - ... - runtime->hw = snd_mychip_playback_hw; /* common definition */ - if (chip->model == VERY_OLD_ONE) - runtime->hw.channels_max = 1; -]]> - - - - - - Typically, you'll have a hardware descriptor as below: - - - - - - - - - - - The info field contains the type and - capabilities of this pcm. The bit flags are defined in - <sound/asound.h> as - SNDRV_PCM_INFO_XXX. Here, at least, you - have to specify whether the mmap is supported and which - interleaved format is supported. - When the is supported, add the - SNDRV_PCM_INFO_MMAP flag here. When the - hardware supports the interleaved or the non-interleaved - formats, SNDRV_PCM_INFO_INTERLEAVED or - SNDRV_PCM_INFO_NONINTERLEAVED flag must - be set, respectively. If both are supported, you can set both, - too. - - - - In the above example, MMAP_VALID and - BLOCK_TRANSFER are specified for the OSS mmap - mode. Usually both are set. Of course, - MMAP_VALID is set only if the mmap is - really supported. - - - - The other possible flags are - SNDRV_PCM_INFO_PAUSE and - SNDRV_PCM_INFO_RESUME. The - PAUSE bit means that the pcm supports the - pause operation, while the - RESUME bit means that the pcm supports - the full suspend/resume operation. - If the PAUSE flag is set, - the trigger callback below - must handle the corresponding (pause push/release) commands. - The suspend/resume trigger commands can be defined even without - the RESUME flag. See - Power Management section for details. - - - - When the PCM substreams can be synchronized (typically, - synchronized start/stop of a playback and a capture streams), - you can give SNDRV_PCM_INFO_SYNC_START, - too. In this case, you'll need to check the linked-list of - PCM substreams in the trigger callback. This will be - described in the later section. - - - - - - formats field contains the bit-flags - of supported formats (SNDRV_PCM_FMTBIT_XXX). - If the hardware supports more than one format, give all or'ed - bits. In the example above, the signed 16bit little-endian - format is specified. - - - - - - rates field contains the bit-flags of - supported rates (SNDRV_PCM_RATE_XXX). - When the chip supports continuous rates, pass - CONTINUOUS bit additionally. - The pre-defined rate bits are provided only for typical - rates. If your chip supports unconventional rates, you need to add - the KNOT bit and set up the hardware - constraint manually (explained later). - - - - - - rate_min and - rate_max define the minimum and - maximum sample rate. This should correspond somehow to - rates bits. - - - - - - channel_min and - channel_max - define, as you might already expected, the minimum and maximum - number of channels. - - - - - - buffer_bytes_max defines the - maximum buffer size in bytes. There is no - buffer_bytes_min field, since - it can be calculated from the minimum period size and the - minimum number of periods. - Meanwhile, period_bytes_min and - define the minimum and maximum size of the period in bytes. - periods_max and - periods_min define the maximum and - minimum number of periods in the buffer. - - - - The period is a term that corresponds to - a fragment in the OSS world. The period defines the size at - which a PCM interrupt is generated. This size strongly - depends on the hardware. - Generally, the smaller period size will give you more - interrupts, that is, more controls. - In the case of capture, this size defines the input latency. - On the other hand, the whole buffer size defines the - output latency for the playback direction. - - - - - - There is also a field fifo_size. - This specifies the size of the hardware FIFO, but currently it - is neither used in the driver nor in the alsa-lib. So, you - can ignore this field. - - - - -

- PCM Configurations - - Ok, let's go back again to the PCM runtime records. - The most frequently referred records in the runtime instance are - the PCM configurations. - The PCM configurations are stored in the runtime instance - after the application sends hw_params data via - alsa-lib. There are many fields copied from hw_params and - sw_params structs. For example, - format holds the format type - chosen by the application. This field contains the enum value - SNDRV_PCM_FORMAT_XXX. - - - - One thing to be noted is that the configured buffer and period - sizes are stored in frames in the runtime. - In the ALSA world, 1 frame = channels * samples-size. - For conversion between frames and bytes, you can use the - frames_to_bytes() and - bytes_to_frames() helper functions. - - -period_size); -]]> - - - - - - Also, many software parameters (sw_params) are - stored in frames, too. Please check the type of the field. - snd_pcm_uframes_t is for the frames as unsigned - integer while snd_pcm_sframes_t is for the frames - as signed integer. - -
- -
- DMA Buffer Information - - The DMA buffer is defined by the following four fields, - dma_area, - dma_addr, - dma_bytes and - dma_private. - The dma_area holds the buffer - pointer (the logical address). You can call - memcpy from/to - this pointer. Meanwhile, dma_addr - holds the physical address of the buffer. This field is - specified only when the buffer is a linear buffer. - dma_bytes holds the size of buffer - in bytes. dma_private is used for - the ALSA DMA allocator. - - - - If you use a standard ALSA function, - snd_pcm_lib_malloc_pages(), for - allocating the buffer, these fields are set by the ALSA middle - layer, and you should not change them by - yourself. You can read them but not write them. - On the other hand, if you want to allocate the buffer by - yourself, you'll need to manage it in hw_params callback. - At least, dma_bytes is mandatory. - dma_area is necessary when the - buffer is mmapped. If your driver doesn't support mmap, this - field is not necessary. dma_addr - is also optional. You can use - dma_private as you like, too. - -
- -
- Running Status - - The running status can be referred via runtime->status. - This is the pointer to the struct snd_pcm_mmap_status - record. For example, you can get the current DMA hardware - pointer via runtime->status->hw_ptr. - - - - The DMA application pointer can be referred via - runtime->control, which points to the - struct snd_pcm_mmap_control record. - However, accessing directly to this value is not recommended. - -
- -
- Private Data - - You can allocate a record for the substream and store it in - runtime->private_data. Usually, this - is done in - - the open callback. - Don't mix this with pcm->private_data. - The pcm->private_data usually points to the - chip instance assigned statically at the creation of PCM, while the - runtime->private_data points to a dynamic - data structure created at the PCM open callback. - - - -runtime->private_data = data; - .... - } -]]> - - - - - - The allocated object must be released in - - the close callback. - -
- -
- Interrupt Callbacks - - The field transfer_ack_begin and - transfer_ack_end are called at - the beginning and at the end of - snd_pcm_period_elapsed(), respectively. - -
- -
- -
- Operators - - OK, now let me give details about each pcm callback - (ops). In general, every callback must - return 0 if successful, or a negative error number - such as -EINVAL. To choose an appropriate - error number, it is advised to check what value other parts of - the kernel return when the same kind of request fails. - - - - The callback function takes at least the argument with - snd_pcm_substream pointer. To retrieve - the chip record from the given substream instance, you can use the - following macro. - - - - - - - - The macro reads substream->private_data, - which is a copy of pcm->private_data. - You can override the former if you need to assign different data - records per PCM substream. For example, the cmi8330 driver assigns - different private_data for playback and capture directions, - because it uses two different codecs (SB- and AD-compatible) for - different directions. - - -
- open callback - - - - - - - - This is called when a pcm substream is opened. - - - - At least, here you have to initialize the runtime->hw - record. Typically, this is done by like this: - - - -runtime; - - runtime->hw = snd_mychip_playback_hw; - return 0; - } -]]> - - - - where snd_mychip_playback_hw is the - pre-defined hardware description. - - - - You can allocate a private data in this callback, as described - in - Private Data section. - - - - If the hardware configuration needs more constraints, set the - hardware constraints here, too. - See - Constraints for more details. - -
- -
- close callback - - - - - - - - Obviously, this is called when a pcm substream is closed. - - - - Any private instance for a pcm substream allocated in the - open callback will be released here. - - - -runtime->private_data); - .... - } -]]> - - - -
- -
- ioctl callback - - This is used for any special call to pcm ioctls. But - usually you can pass a generic ioctl callback, - snd_pcm_lib_ioctl. - -
- -
- hw_params callback - - - - - - - - - - This is called when the hardware parameter - (hw_params) is set - up by the application, - that is, once when the buffer size, the period size, the - format, etc. are defined for the pcm substream. - - - - Many hardware setups should be done in this callback, - including the allocation of buffers. - - - - Parameters to be initialized are retrieved by - params_xxx() macros. To allocate - buffer, you can call a helper function, - - - - - - - - snd_pcm_lib_malloc_pages() is available - only when the DMA buffers have been pre-allocated. - See the section - Buffer Types for more details. - - - - Note that this and prepare callbacks - may be called multiple times per initialization. - For example, the OSS emulation may - call these callbacks at each change via its ioctl. - - - - Thus, you need to be careful not to allocate the same buffers - many times, which will lead to memory leaks! Calling the - helper function above many times is OK. It will release the - previous buffer automatically when it was already allocated. - - - - Another note is that this callback is non-atomic - (schedulable). This is important, because the - trigger callback - is atomic (non-schedulable). That is, mutexes or any - schedule-related functions are not available in - trigger callback. - Please see the subsection - - Atomicity for details. - -
- -
- hw_free callback - - - - - - - - - - This is called to release the resources allocated via - hw_params. For example, releasing the - buffer via - snd_pcm_lib_malloc_pages() is done by - calling the following: - - - - - - - - - - This function is always called before the close callback is called. - Also, the callback may be called multiple times, too. - Keep track whether the resource was already released. - -
- -
- prepare callback - - - - - - - - - - This callback is called when the pcm is - prepared. You can set the format type, sample - rate, etc. here. The difference from - hw_params is that the - prepare callback will be called each - time - snd_pcm_prepare() is called, i.e. when - recovering after underruns, etc. - - - - Note that this callback is now non-atomic. - You can use schedule-related functions safely in this callback. - - - - In this and the following callbacks, you can refer to the - values via the runtime record, - substream->runtime. - For example, to get the current - rate, format or channels, access to - runtime->rate, - runtime->format or - runtime->channels, respectively. - The physical address of the allocated buffer is set to - runtime->dma_area. The buffer and period sizes are - in runtime->buffer_size and runtime->period_size, - respectively. - - - - Be careful that this callback will be called many times at - each setup, too. - -
- -
- trigger callback - - - - - - - - This is called when the pcm is started, stopped or paused. - - - - Which action is specified in the second argument, - SNDRV_PCM_TRIGGER_XXX in - <sound/pcm.h>. At least, - the START and STOP - commands must be defined in this callback. - - - - - - - - - - When the pcm supports the pause operation (given in the info - field of the hardware table), the PAUSE_PUSE - and PAUSE_RELEASE commands must be - handled here, too. The former is the command to pause the pcm, - and the latter to restart the pcm again. - - - - When the pcm supports the suspend/resume operation, - regardless of full or partial suspend/resume support, - the SUSPEND and RESUME - commands must be handled, too. - These commands are issued when the power-management status is - changed. Obviously, the SUSPEND and - RESUME commands - suspend and resume the pcm substream, and usually, they - are identical to the STOP and - START commands, respectively. - See the - Power Management section for details. - - - - As mentioned, this callback is atomic. You cannot call - functions which may sleep. - The trigger callback should be as minimal as possible, - just really triggering the DMA. The other stuff should be - initialized hw_params and prepare callbacks properly - beforehand. - -
- -
- pointer callback - - - - - - - - This callback is called when the PCM middle layer inquires - the current hardware position on the buffer. The position must - be returned in frames, - ranging from 0 to buffer_size - 1. - - - - This is called usually from the buffer-update routine in the - pcm middle layer, which is invoked when - snd_pcm_period_elapsed() is called in the - interrupt routine. Then the pcm middle layer updates the - position and calculates the available space, and wakes up the - sleeping poll threads, etc. - - - - This callback is also atomic. - -
- -
- copy and silence callbacks - - These callbacks are not mandatory, and can be omitted in - most cases. These callbacks are used when the hardware buffer - cannot be in the normal memory space. Some chips have their - own buffer on the hardware which is not mappable. In such a - case, you have to transfer the data manually from the memory - buffer to the hardware buffer. Or, if the buffer is - non-contiguous on both physical and virtual memory spaces, - these callbacks must be defined, too. - - - - If these two callbacks are defined, copy and set-silence - operations are done by them. The detailed will be described in - the later section Buffer and Memory - Management. - -
- -
- ack callback - - This callback is also not mandatory. This callback is called - when the appl_ptr is updated in read or write operations. - Some drivers like emu10k1-fx and cs46xx need to track the - current appl_ptr for the internal buffer, and this callback - is useful only for such a purpose. - - - This callback is atomic. - -
- -
- page callback - - - This callback is optional too. This callback is used - mainly for non-contiguous buffers. The mmap calls this - callback to get the page address. Some examples will be - explained in the later section Buffer and Memory - Management, too. - -
-
- -
- Interrupt Handler - - The rest of pcm stuff is the PCM interrupt handler. The - role of PCM interrupt handler in the sound driver is to update - the buffer position and to tell the PCM middle layer when the - buffer position goes across the prescribed period size. To - inform this, call the snd_pcm_period_elapsed() - function. - - - - There are several types of sound chips to generate the interrupts. - - -
- Interrupts at the period (fragment) boundary - - This is the most frequently found type: the hardware - generates an interrupt at each period boundary. - In this case, you can call - snd_pcm_period_elapsed() at each - interrupt. - - - - snd_pcm_period_elapsed() takes the - substream pointer as its argument. Thus, you need to keep the - substream pointer accessible from the chip instance. For - example, define substream field in the chip record to hold the - current running substream pointer, and set the pointer value - at open callback (and reset at close callback). - - - - If you acquire a spinlock in the interrupt handler, and the - lock is used in other pcm callbacks, too, then you have to - release the lock before calling - snd_pcm_period_elapsed(), because - snd_pcm_period_elapsed() calls other pcm - callbacks inside. - - - - Typical code would be like: - - - Interrupt Handler Case #1 - -lock); - .... - if (pcm_irq_invoked(chip)) { - /* call updater, unlock before it */ - spin_unlock(&chip->lock); - snd_pcm_period_elapsed(chip->substream); - spin_lock(&chip->lock); - /* acknowledge the interrupt if necessary */ - } - .... - spin_unlock(&chip->lock); - return IRQ_HANDLED; - } -]]> - - - -
- -
- High frequency timer interrupts - - This happense when the hardware doesn't generate interrupts - at the period boundary but issues timer interrupts at a fixed - timer rate (e.g. es1968 or ymfpci drivers). - In this case, you need to check the current hardware - position and accumulate the processed sample length at each - interrupt. When the accumulated size exceeds the period - size, call - snd_pcm_period_elapsed() and reset the - accumulator. - - - - Typical code would be like the following. - - - Interrupt Handler Case #2 - -lock); - .... - if (pcm_irq_invoked(chip)) { - unsigned int last_ptr, size; - /* get the current hardware pointer (in frames) */ - last_ptr = get_hw_ptr(chip); - /* calculate the processed frames since the - * last update - */ - if (last_ptr < chip->last_ptr) - size = runtime->buffer_size + last_ptr - - chip->last_ptr; - else - size = last_ptr - chip->last_ptr; - /* remember the last updated point */ - chip->last_ptr = last_ptr; - /* accumulate the size */ - chip->size += size; - /* over the period boundary? */ - if (chip->size >= runtime->period_size) { - /* reset the accumulator */ - chip->size %= runtime->period_size; - /* call updater */ - spin_unlock(&chip->lock); - snd_pcm_period_elapsed(substream); - spin_lock(&chip->lock); - } - /* acknowledge the interrupt if necessary */ - } - .... - spin_unlock(&chip->lock); - return IRQ_HANDLED; - } -]]> - - - -
- -
- On calling <function>snd_pcm_period_elapsed()</function> - - In both cases, even if more than one period are elapsed, you - don't have to call - snd_pcm_period_elapsed() many times. Call - only once. And the pcm layer will check the current hardware - pointer and update to the latest status. - -
-
- -
- Atomicity - - One of the most important (and thus difficult to debug) problems - in kernel programming are race conditions. - In the Linux kernel, they are usually avoided via spin-locks, mutexes - or semaphores. In general, if a race condition can happen - in an interrupt handler, it has to be managed atomically, and you - have to use a spinlock to protect the critical session. If the - critical section is not in interrupt handler code and - if taking a relatively long time to execute is acceptable, you - should use mutexes or semaphores instead. - - - - As already seen, some pcm callbacks are atomic and some are - not. For example, the hw_params callback is - non-atomic, while trigger callback is - atomic. This means, the latter is called already in a spinlock - held by the PCM middle layer. Please take this atomicity into - account when you choose a locking scheme in the callbacks. - - - - In the atomic callbacks, you cannot use functions which may call - schedule or go to - sleep. Semaphores and mutexes can sleep, - and hence they cannot be used inside the atomic callbacks - (e.g. trigger callback). - To implement some delay in such a callback, please use - udelay() or mdelay(). - - - - All three atomic callbacks (trigger, pointer, and ack) are - called with local interrupts disabled. - - -
-
- Constraints - - If your chip supports unconventional sample rates, or only the - limited samples, you need to set a constraint for the - condition. - - - - For example, in order to restrict the sample rates in the some - supported values, use - snd_pcm_hw_constraint_list(). - You need to call this function in the open callback. - - - Example of Hardware Constraints - -runtime, 0, - SNDRV_PCM_HW_PARAM_RATE, - &constraints_rates); - if (err < 0) - return err; - .... - } -]]> - - - - - - There are many different constraints. - Look at sound/pcm.h for a complete list. - You can even define your own constraint rules. - For example, let's suppose my_chip can manage a substream of 1 channel - if and only if the format is S16_LE, otherwise it supports any format - specified in the snd_pcm_hardware structure (or in any - other constraint_list). You can build a rule like this: - - - Example of Hardware Constraints for Channels - -min < 2) { - fmt.bits[0] &= SNDRV_PCM_FMTBIT_S16_LE; - return snd_mask_refine(f, &fmt); - } - return 0; - } -]]> - - - - - - Then you need to call this function to add your rule: - - - -runtime, 0, SNDRV_PCM_HW_PARAM_CHANNELS, - hw_rule_channels_by_format, 0, SNDRV_PCM_HW_PARAM_FORMAT, - -1); -]]> - - - - - - The rule function is called when an application sets the number of - channels. But an application can set the format before the number of - channels. Thus you also need to define the inverse rule: - - - Example of Hardware Constraints for Channels - -bits[0] == SNDRV_PCM_FMTBIT_S16_LE) { - ch.min = ch.max = 1; - ch.integer = 1; - return snd_interval_refine(c, &ch); - } - return 0; - } -]]> - - - - - - ...and in the open callback: - - -runtime, 0, SNDRV_PCM_HW_PARAM_FORMAT, - hw_rule_format_by_channels, 0, SNDRV_PCM_HW_PARAM_CHANNELS, - -1); -]]> - - - - - - I won't give more details here, rather I - would like to say, Luke, use the source. - -
- - - - - - - - - Control Interface - -
- General - - The control interface is used widely for many switches, - sliders, etc. which are accessed from user-space. Its most - important use is the mixer interface. In other words, since ALSA - 0.9.x, all the mixer stuff is implemented on the control kernel API. - - - - ALSA has a well-defined AC97 control module. If your chip - supports only the AC97 and nothing else, you can skip this - section. - - - - The control API is defined in - <sound/control.h>. - Include this file if you want to add your own controls. - -
- -
- Definition of Controls - - To create a new control, you need to define the - following three - callbacks: info, - get and - put. Then, define a - struct snd_kcontrol_new record, such as: - - - Definition of a Control - - - - - - - - Most likely the control is created via - snd_ctl_new1(), and in such a case, you can - add the __devinitdata prefix to the - definition as above. - - - - The iface field specifies the control - type, SNDRV_CTL_ELEM_IFACE_XXX, which - is usually MIXER. - Use CARD for global controls that are not - logically part of the mixer. - If the control is closely associated with some specific device on - the sound card, use HWDEP, - PCM, RAWMIDI, - TIMER, or SEQUENCER, and - specify the device number with the - device and - subdevice fields. - - - - The name is the name identifier - string. Since ALSA 0.9.x, the control name is very important, - because its role is classified from its name. There are - pre-defined standard control names. The details are described in - the - Control Names subsection. - - - - The index field holds the index number - of this control. If there are several different controls with - the same name, they can be distinguished by the index - number. This is the case when - several codecs exist on the card. If the index is zero, you can - omit the definition above. - - - - The access field contains the access - type of this control. Give the combination of bit masks, - SNDRV_CTL_ELEM_ACCESS_XXX, there. - The details will be explained in - the - Access Flags subsection. - - - - The private_value field contains - an arbitrary long integer value for this record. When using - the generic info, - get and - put callbacks, you can pass a value - through this field. If several small numbers are necessary, you can - combine them in bitwise. Or, it's possible to give a pointer - (casted to unsigned long) of some record to this field, too. - - - - The tlv field can be used to provide - metadata about the control; see the - - Metadata subsection. - - - - The other three are - - callback functions. - -
- -
- Control Names - - There are some standards to define the control names. A - control is usually defined from the three parts as - SOURCE DIRECTION FUNCTION. - - - - The first, SOURCE, specifies the source - of the control, and is a string such as Master, - PCM, CD and - Line. There are many pre-defined sources. - - - - The second, DIRECTION, is one of the - following strings according to the direction of the control: - Playback, Capture, Bypass - Playback and Bypass Capture. Or, it can - be omitted, meaning both playback and capture directions. - - - - The third, FUNCTION, is one of the - following strings according to the function of the control: - Switch, Volume and - Route. - - - - The example of control names are, thus, Master Capture - Switch or PCM Playback Volume. - - - - There are some exceptions: - - -
- Global capture and playback - - Capture Source, Capture Switch - and Capture Volume are used for the global - capture (input) source, switch and volume. Similarly, - Playback Switch and Playback - Volume are used for the global output gain switch and - volume. - -
- -
- Tone-controls - - tone-control switch and volumes are specified like - Tone Control - XXX, e.g. Tone Control - - Switch, Tone Control - Bass, - Tone Control - Center. - -
- -
- 3D controls - - 3D-control switches and volumes are specified like 3D - Control - XXX, e.g. 3D Control - - Switch, 3D Control - Center, 3D - Control - Space. - -
- -
- Mic boost - - Mic-boost switch is set as Mic Boost or - Mic Boost (6dB). - - - - More precise information can be found in - Documentation/sound/alsa/ControlNames.txt. - -
-
- -
- Access Flags - - - The access flag is the bitmask which specifies the access type - of the given control. The default access type is - SNDRV_CTL_ELEM_ACCESS_READWRITE, - which means both read and write are allowed to this control. - When the access flag is omitted (i.e. = 0), it is - considered as READWRITE access as default. - - - - When the control is read-only, pass - SNDRV_CTL_ELEM_ACCESS_READ instead. - In this case, you don't have to define - the put callback. - Similarly, when the control is write-only (although it's a rare - case), you can use the WRITE flag instead, and - you don't need the get callback. - - - - If the control value changes frequently (e.g. the VU meter), - VOLATILE flag should be given. This means - that the control may be changed without - - notification. Applications should poll such - a control constantly. - - - - When the control is inactive, set - the INACTIVE flag, too. - There are LOCK and - OWNER flags to change the write - permissions. - - -
- -
- Callbacks - -
- info callback - - The info callback is used to get - detailed information on this control. This must store the - values of the given struct snd_ctl_elem_info - object. For example, for a boolean control with a single - element: - - - Example of info callback - -type = SNDRV_CTL_ELEM_TYPE_BOOLEAN; - uinfo->count = 1; - uinfo->value.integer.min = 0; - uinfo->value.integer.max = 1; - return 0; - } -]]> - - - - - - The type field specifies the type - of the control. There are BOOLEAN, - INTEGER, ENUMERATED, - BYTES, IEC958 and - INTEGER64. The - count field specifies the - number of elements in this control. For example, a stereo - volume would have count = 2. The - value field is a union, and - the values stored are depending on the type. The boolean and - integer types are identical. - - - - The enumerated type is a bit different from others. You'll - need to set the string for the currently given item index. - - - -type = SNDRV_CTL_ELEM_TYPE_ENUMERATED; - uinfo->count = 1; - uinfo->value.enumerated.items = 4; - if (uinfo->value.enumerated.item > 3) - uinfo->value.enumerated.item = 3; - strcpy(uinfo->value.enumerated.name, - texts[uinfo->value.enumerated.item]); - return 0; - } -]]> - - - - - - Some common info callbacks are available for your convenience: - snd_ctl_boolean_mono_info() and - snd_ctl_boolean_stereo_info(). - Obviously, the former is an info callback for a mono channel - boolean item, just like snd_myctl_mono_info - above, and the latter is for a stereo channel boolean item. - - -
- -
- get callback - - - This callback is used to read the current value of the - control and to return to user-space. - - - - For example, - - - Example of get callback - -value.integer.value[0] = get_some_value(chip); - return 0; - } -]]> - - - - - - The value field depends on - the type of control as well as on the info callback. For example, - the sb driver uses this field to store the register offset, - the bit-shift and the bit-mask. The - private_value field is set as follows: - - - - - - and is retrieved in callbacks like - - -private_value & 0xff; - int shift = (kcontrol->private_value >> 16) & 0xff; - int mask = (kcontrol->private_value >> 24) & 0xff; - .... - } -]]> - - - - - - In the get callback, - you have to fill all the elements if the - control has more than one elements, - i.e. count > 1. - In the example above, we filled only one element - (value.integer.value[0]) since it's - assumed as count = 1. - -
- -
- put callback - - - This callback is used to write a value from user-space. - - - - For example, - - - Example of put callback - -current_value != - ucontrol->value.integer.value[0]) { - change_current_value(chip, - ucontrol->value.integer.value[0]); - changed = 1; - } - return changed; - } -]]> - - - - As seen above, you have to return 1 if the value is - changed. If the value is not changed, return 0 instead. - If any fatal error happens, return a negative error code as - usual. - - - - As in the get callback, - when the control has more than one elements, - all elements must be evaluated in this callback, too. - -
- -
- Callbacks are not atomic - - All these three callbacks are basically not atomic. - -
-
- -
- Constructor - - When everything is ready, finally we can create a new - control. To create a control, there are two functions to be - called, snd_ctl_new1() and - snd_ctl_add(). - - - - In the simplest way, you can do like this: - - - - - - - - where my_control is the - struct snd_kcontrol_new object defined above, and chip - is the object pointer to be passed to - kcontrol->private_data - which can be referred to in callbacks. - - - - snd_ctl_new1() allocates a new - snd_kcontrol instance (that's why the definition - of my_control can be with - the __devinitdata - prefix), and snd_ctl_add assigns the given - control component to the card. - -
- -
- Change Notification - - If you need to change and update a control in the interrupt - routine, you can call snd_ctl_notify(). For - example, - - - - - - - - This function takes the card pointer, the event-mask, and the - control id pointer for the notification. The event-mask - specifies the types of notification, for example, in the above - example, the change of control values is notified. - The id pointer is the pointer of struct snd_ctl_elem_id - to be notified. - You can find some examples in es1938.c or - es1968.c for hardware volume interrupts. - -
- -
- Metadata - - To provide information about the dB values of a mixer control, use - on of the DECLARE_TLV_xxx macros from - <sound/tlv.h> to define a variable - containing this information, set thetlv.p - field to point to this variable, and include the - SNDRV_CTL_ELEM_ACCESS_TLV_READ flag in the - access field; like this: - - - - - - - - - The DECLARE_TLV_DB_SCALE macro defines - information about a mixer control where each step in the control's - value changes the dB value by a constant dB amount. - The first parameter is the name of the variable to be defined. - The second parameter is the minimum value, in units of 0.01 dB. - The third parameter is the step size, in units of 0.01 dB. - Set the fourth parameter to 1 if the minimum value actually mutes - the control. - - - - The DECLARE_TLV_DB_LINEAR macro defines - information about a mixer control where the control's value affects - the output linearly. - The first parameter is the name of the variable to be defined. - The second parameter is the minimum value, in units of 0.01 dB. - The third parameter is the maximum value, in units of 0.01 dB. - If the minimum value mutes the control, set the second parameter to - TLV_DB_GAIN_MUTE. - -
- - - - - - - - - API for AC97 Codec - -
- General - - The ALSA AC97 codec layer is a well-defined one, and you don't - have to write much code to control it. Only low-level control - routines are necessary. The AC97 codec API is defined in - <sound/ac97_codec.h>. - -
- -

- Constructor - - To create an ac97 instance, first call snd_ac97_bus - with an ac97_bus_ops_t record with callback functions. - - - - - - - - The bus record is shared among all belonging ac97 instances. - - - - And then call snd_ac97_mixer() with an - struct snd_ac97_template - record together with the bus pointer created above. - - - -ac97); -]]> - - - - where chip->ac97 is a pointer to a newly created - ac97_t instance. - In this case, the chip pointer is set as the private data, so that - the read/write callback functions can refer to this chip instance. - This instance is not necessarily stored in the chip - record. If you need to change the register values from the - driver, or need the suspend/resume of ac97 codecs, keep this - pointer to pass to the corresponding functions. - -
- -
- Callbacks - - The standard callbacks are read and - write. Obviously they - correspond to the functions for read and write accesses to the - hardware low-level codes. - - - - The read callback returns the - register value specified in the argument. - - - -private_data; - .... - return the_register_value; - } -]]> - - - - Here, the chip can be cast from ac97->private_data. - - - - Meanwhile, the write callback is - used to set the register value. - - - - - - - - - - These callbacks are non-atomic like the control API callbacks. - - - - There are also other callbacks: - reset, - wait and - init. - - - - The reset callback is used to reset - the codec. If the chip requires a special kind of reset, you can - define this callback. - - - - The wait callback is used to - add some waiting time in the standard initialization of the codec. If the - chip requires the extra waiting time, define this callback. - - - - The init callback is used for - additional initialization of the codec. - -
- -
- Updating Registers in The Driver - - If you need to access to the codec from the driver, you can - call the following functions: - snd_ac97_write(), - snd_ac97_read(), - snd_ac97_update() and - snd_ac97_update_bits(). - - - - Both snd_ac97_write() and - snd_ac97_update() functions are used to - set a value to the given register - (AC97_XXX). The difference between them is - that snd_ac97_update() doesn't write a - value if the given value has been already set, while - snd_ac97_write() always rewrites the - value. - - - - - - - - - - snd_ac97_read() is used to read the value - of the given register. For example, - - - - - - - - - - snd_ac97_update_bits() is used to update - some bits in the given register. - - - - - - - - - - Also, there is a function to change the sample rate (of a - given register such as - AC97_PCM_FRONT_DAC_RATE) when VRA or - DRA is supported by the codec: - snd_ac97_set_rate(). - - - - - - - - - - The following registers are available to set the rate: - AC97_PCM_MIC_ADC_RATE, - AC97_PCM_FRONT_DAC_RATE, - AC97_PCM_LR_ADC_RATE, - AC97_SPDIF. When - AC97_SPDIF is specified, the register is - not really changed but the corresponding IEC958 status bits will - be updated. - -
- -
- Clock Adjustment - - In some chips, the clock of the codec isn't 48000 but using a - PCI clock (to save a quartz!). In this case, change the field - bus->clock to the corresponding - value. For example, intel8x0 - and es1968 drivers have their own function to read from the clock. - -
- -
- Proc Files - - The ALSA AC97 interface will create a proc file such as - /proc/asound/card0/codec97#0/ac97#0-0 and - ac97#0-0+regs. You can refer to these files to - see the current status and registers of the codec. - -
- -
- Multiple Codecs - - When there are several codecs on the same card, you need to - call snd_ac97_mixer() multiple times with - ac97.num=1 or greater. The num field - specifies the codec number. - - - - If you set up multiple codecs, you either need to write - different callbacks for each codec or check - ac97->num in the callback routines. - -
- - - - - - - - - MIDI (MPU401-UART) Interface - -
- General - - Many soundcards have built-in MIDI (MPU401-UART) - interfaces. When the soundcard supports the standard MPU401-UART - interface, most likely you can use the ALSA MPU401-UART API. The - MPU401-UART API is defined in - <sound/mpu401.h>. - - - - Some soundchips have a similar but slightly different - implementation of mpu401 stuff. For example, emu10k1 has its own - mpu401 routines. - -
- -
- Constructor - - To create a rawmidi object, call - snd_mpu401_uart_new(). - - - - - - - - - - The first argument is the card pointer, and the second is the - index of this component. You can create up to 8 rawmidi - devices. - - - - The third argument is the type of the hardware, - MPU401_HW_XXX. If it's not a special one, - you can use MPU401_HW_MPU401. - - - - The 4th argument is the I/O port address. Many - backward-compatible MPU401 have an I/O port such as 0x330. Or, it - might be a part of its own PCI I/O region. It depends on the - chip design. - - - - The 5th argument is a bitflag for additional information. - When the I/O port address above is part of the PCI I/O - region, the MPU401 I/O port might have been already allocated - (reserved) by the driver itself. In such a case, pass a bit flag - MPU401_INFO_INTEGRATED, - and the mpu401-uart layer will allocate the I/O ports by itself. - - - - When the controller supports only the input or output MIDI stream, - pass the MPU401_INFO_INPUT or - MPU401_INFO_OUTPUT bitflag, respectively. - Then the rawmidi instance is created as a single stream. - - - - MPU401_INFO_MMIO bitflag is used to change - the access method to MMIO (via readb and writeb) instead of - iob and outb. In this case, you have to pass the iomapped address - to snd_mpu401_uart_new(). - - - - When MPU401_INFO_TX_IRQ is set, the output - stream isn't checked in the default interrupt handler. The driver - needs to call snd_mpu401_uart_interrupt_tx() - by itself to start processing the output stream in the irq handler. - - - - Usually, the port address corresponds to the command port and - port + 1 corresponds to the data port. If not, you may change - the cport field of - struct snd_mpu401 manually - afterward. However, snd_mpu401 pointer is not - returned explicitly by - snd_mpu401_uart_new(). You need to cast - rmidi->private_data to - snd_mpu401 explicitly, - - - -private_data; -]]> - - - - and reset the cport as you like: - - - -cport = my_own_control_port; -]]> - - - - - - The 6th argument specifies the irq number for UART. If the irq - is already allocated, pass 0 to the 7th argument - (irq_flags). Otherwise, pass the flags - for irq allocation - (SA_XXX bits) to it, and the irq will be - reserved by the mpu401-uart layer. If the card doesn't generate - UART interrupts, pass -1 as the irq number. Then a timer - interrupt will be invoked for polling. - -
- -
- Interrupt Handler - - When the interrupt is allocated in - snd_mpu401_uart_new(), the private - interrupt handler is used, hence you don't have anything else to do - than creating the mpu401 stuff. Otherwise, you have to call - snd_mpu401_uart_interrupt() explicitly when - a UART interrupt is invoked and checked in your own interrupt - handler. - - - - In this case, you need to pass the private_data of the - returned rawmidi object from - snd_mpu401_uart_new() as the second - argument of snd_mpu401_uart_interrupt(). - - - -private_data, regs); -]]> - - - -
- - - - - - - - - RawMIDI Interface - -
- Overview - - - The raw MIDI interface is used for hardware MIDI ports that can - be accessed as a byte stream. It is not used for synthesizer - chips that do not directly understand MIDI. - - - - ALSA handles file and buffer management. All you have to do is - to write some code to move data between the buffer and the - hardware. - - - - The rawmidi API is defined in - <sound/rawmidi.h>. - -
- -
- Constructor - - - To create a rawmidi device, call the - snd_rawmidi_new function: - - -card, "MyMIDI", 0, outs, ins, &rmidi); - if (err < 0) - return err; - rmidi->private_data = chip; - strcpy(rmidi->name, "My MIDI"); - rmidi->info_flags = SNDRV_RAWMIDI_INFO_OUTPUT | - SNDRV_RAWMIDI_INFO_INPUT | - SNDRV_RAWMIDI_INFO_DUPLEX; -]]> - - - - - - The first argument is the card pointer, the second argument is - the ID string. - - - - The third argument is the index of this component. You can - create up to 8 rawmidi devices. - - - - The fourth and fifth arguments are the number of output and - input substreams, respectively, of this device (a substream is - the equivalent of a MIDI port). - - - - Set the info_flags field to specify - the capabilities of the device. - Set SNDRV_RAWMIDI_INFO_OUTPUT if there is - at least one output port, - SNDRV_RAWMIDI_INFO_INPUT if there is at - least one input port, - and SNDRV_RAWMIDI_INFO_DUPLEX if the device - can handle output and input at the same time. - - - - After the rawmidi device is created, you need to set the - operators (callbacks) for each substream. There are helper - functions to set the operators for all the substreams of a device: - - - - - - - - - The operators are usually defined like this: - - - - - - These callbacks are explained in the Callbacks - section. - - - - If there are more than one substream, you should give a - unique name to each of them: - - -streams[SNDRV_RAWMIDI_STREAM_OUTPUT].substreams, - list { - sprintf(substream->name, "My MIDI Port %d", substream->number + 1); - } - /* same for SNDRV_RAWMIDI_STREAM_INPUT */ -]]> - - - -
- -
- Callbacks - - - In all the callbacks, the private data that you've set for the - rawmidi device can be accessed as - substream->rmidi->private_data. - - - - - If there is more than one port, your callbacks can determine the - port index from the struct snd_rawmidi_substream data passed to each - callback: - - -number; -]]> - - - - -
- <function>open</function> callback - - - - - - - - - This is called when a substream is opened. - You can initialize the hardware here, but you shouldn't - start transmitting/receiving data yet. - -
- -
- <function>close</function> callback - - - - - - - - - Guess what. - - - - The open and close - callbacks of a rawmidi device are serialized with a mutex, - and can sleep. - -
- -
- <function>trigger</function> callback for output - substreams - - - - - - - - - This is called with a nonzero up - parameter when there is some data in the substream buffer that - must be transmitted. - - - - To read data from the buffer, call - snd_rawmidi_transmit_peek. It will - return the number of bytes that have been read; this will be - less than the number of bytes requested when there are no more - data in the buffer. - After the data have been transmitted successfully, call - snd_rawmidi_transmit_ack to remove the - data from the substream buffer: - - - - - - - - - If you know beforehand that the hardware will accept data, you - can use the snd_rawmidi_transmit function - which reads some data and removes them from the buffer at once: - - - - - - - - - If you know beforehand how many bytes you can accept, you can - use a buffer size greater than one with the - snd_rawmidi_transmit* functions. - - - - The trigger callback must not sleep. If - the hardware FIFO is full before the substream buffer has been - emptied, you have to continue transmitting data later, either - in an interrupt handler, or with a timer if the hardware - doesn't have a MIDI transmit interrupt. - - - - The trigger callback is called with a - zero up parameter when the transmission - of data should be aborted. - -
- -
- <function>trigger</function> callback for input - substreams - - - - - - - - - This is called with a nonzero up - parameter to enable receiving data, or with a zero - up parameter do disable receiving data. - - - - The trigger callback must not sleep; the - actual reading of data from the device is usually done in an - interrupt handler. - - - - When data reception is enabled, your interrupt handler should - call snd_rawmidi_receive for all received - data: - - - - - - -
- -
- <function>drain</function> callback - - - - - - - - - This is only used with output substreams. This function should wait - until all data read from the substream buffer have been transmitted. - This ensures that the device can be closed and the driver unloaded - without losing data. - - - - This callback is optional. If you do not set - drain in the struct snd_rawmidi_ops - structure, ALSA will simply wait for 50 milliseconds - instead. - -
-
- - - - - - - - - Miscellaneous Devices - -
- FM OPL3 - - The FM OPL3 is still used in many chips (mainly for backward - compatibility). ALSA has a nice OPL3 FM control layer, too. The - OPL3 API is defined in - <sound/opl3.h>. - - - - FM registers can be directly accessed through the direct-FM API, - defined in <sound/asound_fm.h>. In - ALSA native mode, FM registers are accessed through - the Hardware-Dependant Device direct-FM extension API, whereas in - OSS compatible mode, FM registers can be accessed with the OSS - direct-FM compatible API in /dev/dmfmX device. - - - - To create the OPL3 component, you have two functions to - call. The first one is a constructor for the opl3_t - instance. - - - - - - - - - - The first argument is the card pointer, the second one is the - left port address, and the third is the right port address. In - most cases, the right port is placed at the left port + 2. - - - - The fourth argument is the hardware type. - - - - When the left and right ports have been already allocated by - the card driver, pass non-zero to the fifth argument - (integrated). Otherwise, the opl3 module will - allocate the specified ports by itself. - - - - When the accessing the hardware requires special method - instead of the standard I/O access, you can create opl3 instance - separately with snd_opl3_new(). - - - - - - - - - - Then set command, - private_data and - private_free for the private - access function, the private data and the destructor. - The l_port and r_port are not necessarily set. Only the - command must be set properly. You can retrieve the data - from the opl3->private_data field. - - - - After creating the opl3 instance via snd_opl3_new(), - call snd_opl3_init() to initialize the chip to the - proper state. Note that snd_opl3_create() always - calls it internally. - - - - If the opl3 instance is created successfully, then create a - hwdep device for this opl3. - - - - - - - - - - The first argument is the opl3_t instance you - created, and the second is the index number, usually 0. - - - - The third argument is the index-offset for the sequencer - client assigned to the OPL3 port. When there is an MPU401-UART, - give 1 for here (UART always takes 0). - -
- -
- Hardware-Dependent Devices - - Some chips need user-space access for special - controls or for loading the micro code. In such a case, you can - create a hwdep (hardware-dependent) device. The hwdep API is - defined in <sound/hwdep.h>. You can - find examples in opl3 driver or - isa/sb/sb16_csp.c. - - - - The creation of the hwdep instance is done via - snd_hwdep_new(). - - - - - - - - where the third argument is the index number. - - - - You can then pass any pointer value to the - private_data. - If you assign a private data, you should define the - destructor, too. The destructor function is set in - the private_free field. - - - -private_data = p; - hw->private_free = mydata_free; -]]> - - - - and the implementation of the destructor would be: - - - -private_data; - kfree(p); - } -]]> - - - - - - The arbitrary file operations can be defined for this - instance. The file operators are defined in - the ops table. For example, assume that - this chip needs an ioctl. - - - -ops.open = mydata_open; - hw->ops.ioctl = mydata_ioctl; - hw->ops.release = mydata_release; -]]> - - - - And implement the callback functions as you like. - -
- -
- IEC958 (S/PDIF) - - Usually the controls for IEC958 devices are implemented via - the control interface. There is a macro to compose a name string for - IEC958 controls, SNDRV_CTL_NAME_IEC958() - defined in <include/asound.h>. - - - - There are some standard controls for IEC958 status bits. These - controls use the type SNDRV_CTL_ELEM_TYPE_IEC958, - and the size of element is fixed as 4 bytes array - (value.iec958.status[x]). For the info - callback, you don't specify - the value field for this type (the count field must be set, - though). - - - - IEC958 Playback Con Mask is used to return the - bit-mask for the IEC958 status bits of consumer mode. Similarly, - IEC958 Playback Pro Mask returns the bitmask for - professional mode. They are read-only controls, and are defined - as MIXER controls (iface = - SNDRV_CTL_ELEM_IFACE_MIXER). - - - - Meanwhile, IEC958 Playback Default control is - defined for getting and setting the current default IEC958 - bits. Note that this one is usually defined as a PCM control - (iface = SNDRV_CTL_ELEM_IFACE_PCM), - although in some places it's defined as a MIXER control. - - - - In addition, you can define the control switches to - enable/disable or to set the raw bit mode. The implementation - will depend on the chip, but the control should be named as - IEC958 xxx, preferably using - the SNDRV_CTL_NAME_IEC958() macro. - - - - You can find several cases, for example, - pci/emu10k1, - pci/ice1712, or - pci/cmipci.c. - -
- - - - - - - - - Buffer and Memory Management - -
- Buffer Types - - ALSA provides several different buffer allocation functions - depending on the bus and the architecture. All these have a - consistent API. The allocation of physically-contiguous pages is - done via - snd_malloc_xxx_pages() function, where xxx - is the bus type. - - - - The allocation of pages with fallback is - snd_malloc_xxx_pages_fallback(). This - function tries to allocate the specified pages but if the pages - are not available, it tries to reduce the page sizes until - enough space is found. - - - - The release the pages, call - snd_free_xxx_pages() function. - - - - Usually, ALSA drivers try to allocate and reserve - a large contiguous physical space - at the time the module is loaded for the later use. - This is called pre-allocation. - As already written, you can call the following function at - pcm instance construction time (in the case of PCI bus). - - - - - - - - where size is the byte size to be - pre-allocated and the max is the maximum - size to be changed via the prealloc proc file. - The allocator will try to get an area as large as possible - within the given size. - - - - The second argument (type) and the third argument (device pointer) - are dependent on the bus. - In the case of the ISA bus, pass snd_dma_isa_data() - as the third argument with SNDRV_DMA_TYPE_DEV type. - For the continuous buffer unrelated to the bus can be pre-allocated - with SNDRV_DMA_TYPE_CONTINUOUS type and the - snd_dma_continuous_data(GFP_KERNEL) device pointer, - where GFP_KERNEL is the kernel allocation flag to - use. - For the PCI scatter-gather buffers, use - SNDRV_DMA_TYPE_DEV_SG with - snd_dma_pci_data(pci) - (see the - Non-Contiguous Buffers - section). - - - - Once the buffer is pre-allocated, you can use the - allocator in the hw_params callback: - - - - - - - - Note that you have to pre-allocate to use this function. - -
- -
- External Hardware Buffers - - Some chips have their own hardware buffers and the DMA - transfer from the host memory is not available. In such a case, - you need to either 1) copy/set the audio data directly to the - external hardware buffer, or 2) make an intermediate buffer and - copy/set the data from it to the external hardware buffer in - interrupts (or in tasklets, preferably). - - - - The first case works fine if the external hardware buffer is large - enough. This method doesn't need any extra buffers and thus is - more effective. You need to define the - copy and - silence callbacks for - the data transfer. However, there is a drawback: it cannot - be mmapped. The examples are GUS's GF1 PCM or emu8000's - wavetable PCM. - - - - The second case allows for mmap on the buffer, although you have - to handle an interrupt or a tasklet to transfer the data - from the intermediate buffer to the hardware buffer. You can find an - example in the vxpocket driver. - - - - Another case is when the chip uses a PCI memory-map - region for the buffer instead of the host memory. In this case, - mmap is available only on certain architectures like the Intel one. - In non-mmap mode, the data cannot be transferred as in the normal - way. Thus you need to define the copy and - silence callbacks as well, - as in the cases above. The examples are found in - rme32.c and rme96.c. - - - - The implementation of the copy and - silence callbacks depends upon - whether the hardware supports interleaved or non-interleaved - samples. The copy callback is - defined like below, a bit - differently depending whether the direction is playback or - capture: - - - - - - - - - - In the case of interleaved samples, the second argument - (channel) is not used. The third argument - (pos) points the - current position offset in frames. - - - - The meaning of the fourth argument is different between - playback and capture. For playback, it holds the source data - pointer, and for capture, it's the destination data pointer. - - - - The last argument is the number of frames to be copied. - - - - What you have to do in this callback is again different - between playback and capture directions. In the - playback case, you copy the given amount of data - (count) at the specified pointer - (src) to the specified offset - (pos) on the hardware buffer. When - coded like memcpy-like way, the copy would be like: - - - - - - - - - - For the capture direction, you copy the given amount of - data (count) at the specified offset - (pos) on the hardware buffer to the - specified pointer (dst). - - - - - - - - Note that both the position and the amount of data are given - in frames. - - - - In the case of non-interleaved samples, the implementation - will be a bit more complicated. - - - - You need to check the channel argument, and if it's -1, copy - the whole channels. Otherwise, you have to copy only the - specified channel. Please check - isa/gus/gus_pcm.c as an example. - - - - The silence callback is also - implemented in a similar way. - - - - - - - - - - The meanings of arguments are the same as in the - copy - callback, although there is no src/dst - argument. In the case of interleaved samples, the channel - argument has no meaning, as well as on - copy callback. - - - - The role of silence callback is to - set the given amount - (count) of silence data at the - specified offset (pos) on the hardware - buffer. Suppose that the data format is signed (that is, the - silent-data is 0), and the implementation using a memset-like - function would be like: - - - - - - - - - - In the case of non-interleaved samples, again, the - implementation becomes a bit more complicated. See, for example, - isa/gus/gus_pcm.c. - -
- -
- Non-Contiguous Buffers - - If your hardware supports the page table as in emu10k1 or the - buffer descriptors as in via82xx, you can use the scatter-gather - (SG) DMA. ALSA provides an interface for handling SG-buffers. - The API is provided in <sound/pcm.h>. - - - - For creating the SG-buffer handler, call - snd_pcm_lib_preallocate_pages() or - snd_pcm_lib_preallocate_pages_for_all() - with SNDRV_DMA_TYPE_DEV_SG - in the PCM constructor like other PCI pre-allocator. - You need to pass snd_dma_pci_data(pci), - where pci is the struct pci_dev pointer - of the chip as well. - The struct snd_sg_buf instance is created as - substream->dma_private. You can cast - the pointer like: - - - -dma_private; -]]> - - - - - - Then call snd_pcm_lib_malloc_pages() - in the hw_params callback - as well as in the case of normal PCI buffer. - The SG-buffer handler will allocate the non-contiguous kernel - pages of the given size and map them onto the virtually contiguous - memory. The virtual pointer is addressed in runtime->dma_area. - The physical address (runtime->dma_addr) is set to zero, - because the buffer is physically non-contigous. - The physical address table is set up in sgbuf->table. - You can get the physical address at a certain offset via - snd_pcm_sgbuf_get_addr(). - - - - When a SG-handler is used, you need to set - snd_pcm_sgbuf_ops_page as - the page callback. - (See - page callback section.) - - - - To release the data, call - snd_pcm_lib_free_pages() in the - hw_free callback as usual. - -
- -
- Vmalloc'ed Buffers - - It's possible to use a buffer allocated via - vmalloc, for example, for an intermediate - buffer. Since the allocated pages are not contiguous, you need - to set the page callback to obtain - the physical address at every offset. - - - - The implementation of page callback - would be like this: - - - - - - /* get the physical page pointer on the given offset */ - static struct page *mychip_page(struct snd_pcm_substream *substream, - unsigned long offset) - { - void *pageptr = substream->runtime->dma_area + offset; - return vmalloc_to_page(pageptr); - } -]]> - - - -
- - - - - - - - - Proc Interface - - ALSA provides an easy interface for procfs. The proc files are - very useful for debugging. I recommend you set up proc files if - you write a driver and want to get a running status or register - dumps. The API is found in - <sound/info.h>. - - - - To create a proc file, call - snd_card_proc_new(). - - - - - - - - where the second argument specifies the name of the proc file to be - created. The above example will create a file - my-file under the card directory, - e.g. /proc/asound/card0/my-file. - - - - Like other components, the proc entry created via - snd_card_proc_new() will be registered and - released automatically in the card registration and release - functions. - - - - When the creation is successful, the function stores a new - instance in the pointer given in the third argument. - It is initialized as a text proc file for read only. To use - this proc file as a read-only text file as it is, set the read - callback with a private data via - snd_info_set_text_ops(). - - - - - - - - where the second argument (chip) is the - private data to be used in the callbacks. The third parameter - specifies the read buffer size and the fourth - (my_proc_read) is the callback function, which - is defined like - - - - - - - - - - - In the read callback, use snd_iprintf() for - output strings, which works just like normal - printf(). For example, - - - -private_data; - - snd_iprintf(buffer, "This is my chip!\n"); - snd_iprintf(buffer, "Port = %ld\n", chip->port); - } -]]> - - - - - - The file permissions can be changed afterwards. As default, it's - set as read only for all users. If you want to add write - permission for the user (root as default), do as follows: - - - -mode = S_IFREG | S_IRUGO | S_IWUSR; -]]> - - - - and set the write buffer size and the callback - - - -c.text.write = my_proc_write; -]]> - - - - - - For the write callback, you can use - snd_info_get_line() to get a text line, and - snd_info_get_str() to retrieve a string from - the line.

- General - - So far, you've learned how to write the driver codes. - And you might have a question now: how to put my own - driver into the ALSA driver tree? - Here (finally :) the standard procedure is described briefly. - - - - Suppose that you create a new PCI driver for the card - xyz. The card module name would be - snd-xyz. The new driver is usually put into the alsa-driver - tree, alsa-driver/pci directory in - the case of PCI cards. - Then the driver is evaluated, audited and tested - by developers and users. After a certain time, the driver - will go to the alsa-kernel tree (to the corresponding directory, - such as alsa-kernel/pci) and eventually - will be integrated into the Linux 2.6 tree (the directory would be - linux/sound/pci). - - - - In the following sections, the driver code is supposed - to be put into alsa-driver tree. The two cases are covered: - a driver consisting of a single source file and one consisting - of several source files. - -
- -
- Driver with A Single Source File - - - - - Modify alsa-driver/pci/Makefile - - - - Suppose you have a file xyz.c. Add the following - two lines - - - - - - - - - - - Create the Kconfig entry - - - - Add the new entry of Kconfig for your xyz driver. - - - - - - - the line, select SND_PCM, specifies that the driver xyz supports - PCM. In addition to SND_PCM, the following components are - supported for select command: - SND_RAWMIDI, SND_TIMER, SND_HWDEP, SND_MPU401_UART, - SND_OPL3_LIB, SND_OPL4_LIB, SND_VX_LIB, SND_AC97_CODEC. - Add the select command for each supported component. - - - - Note that some selections imply the lowlevel selections. - For example, PCM includes TIMER, MPU401_UART includes RAWMIDI, - AC97_CODEC includes PCM, and OPL3_LIB includes HWDEP. - You don't need to give the lowlevel selections again. - - - - For the details of Kconfig script, refer to the kbuild - documentation. - - - - - - - Run cvscompile script to re-generate the configure script and - build the whole stuff again. - - - - -
- -
- Drivers with Several Source Files - - Suppose that the driver snd-xyz have several source files. - They are located in the new subdirectory, - pci/xyz. - - - - - Add a new directory (xyz) in - alsa-driver/pci/Makefile as below - - - - - - - - - - - - Under the directory xyz, create a Makefile - - - Sample Makefile for a driver xyz - - - - - - - - - - Create the Kconfig entry - - - - This procedure is as same as in the last section. - - - - - - Run cvscompile script to re-generate the configure script and - build the whole stuff again. - - - - -
- - - - - - - - Useful Functions - -
- <function>snd_printk()</function> and friends - - ALSA provides a verbose version of the - printk() function. If a kernel config - CONFIG_SND_VERBOSE_PRINTK is set, this - function prints the given message together with the file name - and the line of the caller. The KERN_XXX - prefix is processed as - well as the original printk() does, so it's - recommended to add this prefix, e.g. - - - - - - - - - - There are also printk()'s for - debugging. snd_printd() can be used for - general debugging purposes. If - CONFIG_SND_DEBUG is set, this function is - compiled, and works just like - snd_printk(). If the ALSA is compiled - without the debugging flag, it's ignored. - - - - snd_printdd() is compiled in only when - CONFIG_SND_DEBUG_VERBOSE is set. Please note - that CONFIG_SND_DEBUG_VERBOSE is not set as default - even if you configure the alsa-driver with - option. You need to give - explicitly option instead. - -
- -
- <function>snd_BUG()</function> - - It shows the BUG? message and - stack trace as well as snd_BUG_ON at the point. - It's useful to show that a fatal error happens there. - - - When no debug flag is set, this macro is ignored. - -
- -
- <function>snd_BUG_ON()</function> - - snd_BUG_ON() macro is similar with - WARN_ON() macro. For example, - - - - - - - - or it can be used as the condition, - - - - - - - - - - The macro takes an conditional expression to evaluate. - When CONFIG_SND_DEBUG, is set, the - expression is actually evaluated. If it's non-zero, it shows - the warning message such as - BUG? (xxx) - normally followed by stack trace. It returns the evaluated - value. - When no CONFIG_SND_DEBUG is set, this - macro always returns zero. - - -

So in acct_update_integrals we may end up with the following scenario: Between reading tsk->stime/tsk->utime and tsk->acct_timexpd an interrupt happens which updates accouting values. This causes acct_timexpd to be greater than the former stime + utime. The subsequent calculation of dtime = cputime_sub(time, tsk->acct_timexpd); will be negative and the division performed by cputime_to_jiffies(dtime) will generate an exception since the result won't fit into a 32 bit register. In order to fix this just always disable interrupts while accessing any of the accounting values.

This reverts commit e088e4c9cdb618675874becb91b2fd581ee707e6. Removing the sysfs interface for p4-clockmod was flagged as a regression in bug 12826. Course of action: - Find out the remaining causes of overheating, and fix them if possible. ACPI should be doing the right thing automatically. If it isn't, we need to fix that. - mark p4-clockmod ui as deprecated - try again with the removal in six months. It's not really feasible to printk about the deprecation, because it needs to happen at all the sysfs entry points, which means adding a lot of strcmp("p4-clockmod".. calls to the core, which.. bleuch.

"Lots of device drivers register a 'struct device_driver' with the '.bus' member set to '&platform_bus_type'. This is wrong, since the platform_bus functions expect the 'struct device_driver' to be wrapped up in a 'struct platform_driver' which provides some additional callbacks (like suspend_late, resume_early). The effect may be that platform_suspend_late() uses bogus data outside the device_driver struct as a pointer pointer to the device driver's suspend_late() function or other hard to reproduce failures."(Lothar Wassmann) Signed-off-by: Ming Lei Acked-by: Henrique de Moraes Holschuh Acked-by: David Brownell Signed-off-by: Greg Kroah-Hartman diff --git a/arch/mips/basler/excite/excite_iodev.c b/arch/mips/basler/excite/excite_iodev.c index a1e3526..dfbfd7e 100644 --- a/arch/mips/basler/excite/excite_iodev.c +++ b/arch/mips/basler/excite/excite_iodev.c @@ -33,8 +33,8 @@ static const struct resource *iodev_get_resource(struct platform_device *, const char *, unsigned int);

The path displayed is always a relative path to sysfs_root. The leading '/' in the path name refers to the sysfs_root mount point, and should not be confused with the "real" '/'.

Now all platform_driver is registered by platform_driver_register, which makes probe()/release()/... of platform_driver passed parameter of platform_device *, so platform driver can get platform_data from platform_device; 2. Other kind of devices do not need to use platform_data, we can decrease size of device if moving it to platform_device. Taking into consideration of thousands of files to be fixed and they can't be finished in one night(maybe it will take a long time), so we keep platform_data in device to allow two kind of cases coexist until all platform devices pass its platfrom data from platform_device->platform_data.

Vegard Nossum discovered that a poorly written sysfs ->store callback can repeatedly schedule remove callbacks on the same device over and over, e.g. $ while true ; do echo 1 > /sys/devices/.../remove ; done If the 'remove' attribute uses the sysfs_schedule_callback API and also does not protect itself from concurrent accesses, its callback handler will be called multiple times, and will eventually attempt to perform operations on a freed kobject, leading to many problems. Instead of requiring all callers of sysfs_schedule_callback to implement their own synchronization, provide the protection in the infrastructure. Now, sysfs_schedule_callback will only allow one scheduled callback per kobject. On subsequent calls with the same kobject, return -EAGAIN. This is a short term fix. The long term fix is to allow sysfs attributes to remove themselves directly, without any of this callback hokey pokey.

Specifically, the effect is that each uevent that is being sent causes the code to wake up keventd, then block until keventd has processed the work. Needless to say, this happens many times during the system boot. This patches changes that to UHN_NO_WAIT (brilliant name for a constant btw) so that we only schedule the work to fire the uevent message, but do not wait for keventd to process the work. This removes one of the bottlenecks during boot; each one of them is only a small effect, but the sum of them does add up.

It's caught out by the way powerpc's pci_mmap of legacy_mem uses shmem_zero_setup(), substituting a new vma->vm_file whose private_data no longer points to the bin_buffer (substitution done because some versions of X crash if that mmap fails). The fix to this is straightforward: the original vm_file is fput() in that case, so this mmap won't block sysfs at all, so just don't switch over to bin_vm_ops if vm_file has changed. But more fixes made before realizing that was the problem:- It should not be an error if bin_page_mkwrite() finds no underlying page_mkwrite(). Check that a file already mmap'ed has the same underlying vm_ops _before_ pointing vma->vm_ops at bin_vm_ops. If the file being mmap'ed is a shmem/tmpfs file, don't fail the mmap on CONFIG_NUMA=y, just because that has a set_policy and get_policy: provide bin_set_policy, bin_get_policy and bin_migrate.

The new feature of this patchset is a richer /debugfs control file interface, (an example output from my system is at the bottom), which allows fined grained control over the the debug output. The output can be controlled by function, file, module, format string, and line number. for example, enabled all debug messages in module 'nf_conntrack': echo -n 'module nf_conntrack +p' > /mnt/debugfs/dynamic_debug/control to disable them: echo -n 'module nf_conntrack -p' > /mnt/debugfs/dynamic_debug/control A further explanation can be found in the documentation patch.

Currently, if +CONFIG_DYNAMIC_DEBUG is set, then all pr_debug()/dev_debug() calls can be +dynamically enabled per-callsite. + +Dynamic debug has even more useful features: + + * Simple query language allows turning on and off debugging statements by + matching any combination of: + + - source filename + - function name + - line number (including ranges of line numbers) + - module name + - format string + + * Provides a debugfs control file: /dynamic_debug/control which can be + read to display the complete list of known debug statements, to help guide you + +Controlling dynamic debug Behaviour +=============================== + +The behaviour of pr_debug()/dev_debug()s are controlled via writing to a +control file in the 'debugfs' filesystem. Thus, you must first mount the debugfs +filesystem, in order to make use of this feature. Subsequently, we refer to the +control file as: /dynamic_debug/control. For example, if you want to +enable printing from source file 'svcsock.c', line 1603 you simply do: + +nullarbor:~ # echo 'file svcsock.c line 1603 +p' > + /dynamic_debug/control + +If you make a mistake with the syntax, the write will fail thus: + +nullarbor:~ # echo 'file svcsock.c wtf 1 +p' > + /dynamic_debug/control +-bash: echo: write error: Invalid argument + +Viewing Dynamic Debug Behaviour +=========================== + +You can view the currently configured behaviour of all the debug statements +via: + +nullarbor:~ # cat /dynamic_debug/control +# filename:lineno [module]function flags format +/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:323 [svcxprt_rdma]svc_rdma_cleanup - "SVCRDMA\040Module\040Removed,\040deregister\040RPC\040RDMA\040transport\012" +/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:341 [svcxprt_rdma]svc_rdma_init - "\011max_inline\040\040\040\040\040\040\040:\040%d\012" +/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:340 [svcxprt_rdma]svc_rdma_init - "\011sq_depth\040\040\040\040\040\040\040\040\040:\040%d\012" +/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:338 [svcxprt_rdma]svc_rdma_init - "\011max_requests\040\040\040\040\040:\040%d\012" +... + + +You can also apply standard Unix text manipulation filters to this +data, e.g. + +nullarbor:~ # grep -i rdma /dynamic_debug/control | wc -l +62 + +nullarbor:~ # grep -i tcp /dynamic_debug/control | wc -l +42 + +Note in particular that the third column shows the enabled behaviour +flags for each debug statement callsite (see below for definitions of the +flags).

Note that newlines are treated as word +separators and do *not* end a command or allow multiple commands to +be done together. So these are all equivalent: + +nullarbor:~ # echo -c 'file svcsock.c line 1603 +p' > + /dynamic_debug/control +nullarbor:~ # echo -c ' file svcsock.c line 1603 +p ' > + /dynamic_debug/control +nullarbor:~ # echo -c 'file svcsock.c\nline 1603 +p' > + /dynamic_debug/control +nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' > + /dynamic_debug/control + +Commands are bounded by a write() system call. If you want to do +multiple commands you need to do a separate "echo" for each, like: + +nullarbor:~ # echo 'file svcsock.c line 1603 +p' > /proc/dprintk ;\ +> echo 'file svcsock.c line 1563 +p' > /proc/dprintk + +or even like: + +nullarbor:~ # ( +> echo 'file svcsock.c line 1603 +p' ;\ +> echo 'file svcsock.c line 1563 +p' ;\ +> ) > /proc/dprintk + +At the syntactical level, a command comprises a sequence of match +specifications, followed by a flags change specification. + +command ::= match-spec* flags-spec + +The match-spec's are used to choose a subset of the known dprintk() +callsites to which to apply the flags-spec. Think of them as a query +with implicit ANDs between each pair. Note that an empty list of +match-specs is possible, but is not very useful because it will not +match any debug statement callsites. + +A match specification comprises a keyword, which controls the attribute +of the callsite to be compared, and a value to compare against. Possible +keywords are: + +match-spec ::= 'func' string | + 'file' string | + 'module' string | + 'format' string | + 'line' line-range + +line-range ::= lineno | + '-'lineno | + lineno'-' | + lineno'-'lineno +// Note: line-range cannot contain space, e.g. +// "1-30" is valid range but "1 - 30" is not. + +lineno ::= unsigned-int + +The meanings of each keyword are: + +func + The given string is compared against the function name + of each callsite. Example: + + func svc_tcp_accept + +file + The given string is compared against either the full + pathname or the basename of the source file of each + callsite. Examples: + + file svcsock.c + file /usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svcsock.c + +module + The given string is compared against the module name + of each callsite. The module name is the string as + seen in "lsmod", i.e. without the directory or the .ko + suffix and with '-' changed to '_'. Examples: + + module sunrpc + module nfsd + +format + The given string is searched for in the dynamic debug format + string. Note that the string does not need to match the + entire format, only some part. Whitespace and other + special characters can be escaped using C octal character + escape \ooo notation, e.g. the space character is \040. + Examples: + + format svcrdma: // many of the NFS/RDMA server dprintks + format readahead // some dprintks in the readahead cache + format nfsd:\040SETATTR // how to match a format with whitespace + +line + The given line number or range of line numbers is compared + against the line number of each dprintk() callsite. A single + line number matches the callsite line number exactly. A + range of line numbers matches any callsite between the first + and last line number inclusive. An empty first number means + the first line in the file, an empty line number means the + last number in the file.

This feature can reduce total interrupt overhead for RAID setups in some situations, by deferring the interrupt signal until one or both of: a) a specified io_count (completed SATA commands) is achieved, or b) a specified time interval elapses after an IO completion. For now, module parameters are used to set the irq_coalescing_io_count and irq_coalescing_usecs (timeout) globally. These may eventually be supplemented with sysfs attributes, so that thresholds can be set on-the-fly and on a per-chip (or even per-host_controller) basis.

Add a quirk that enables blink mode for the LED while NCQ is enabled on any port of a SoC host controller. Normal LED function is restored when NCQ is not enabled on any port. The code to enable the blink mode is based on earlier code and suggestions from Frans Pop, Saeed Bishara, and possibly others.

This fixes [Bug #12809] iozone regression with 2.6.29-rc6. The iozone benchmarks are performed on a 1200M file, with 8GB ram. iozone -i 0 -i 1 -i 2 -i 3 -i 4 -r 4k -s 64k -s 512m -s 1200m -b tmp.xls iozone -B -r 4k -s 64k -s 512m -s 1200m -b tmp.xls The performance regression is triggered by commit 1cf6e7d83bf3(mm: task dirty accounting fix), which makes more correct/thorough dirty accounting. The default 5/10 dirty ratios were picked (a) with the old dirty logic and (b) largely at random and (c) designed to be aggressive. In particular, that (a) means that having fixed some of the dirty accounting, maybe the real bug is now that it was always too aggressive, just hidden by an accounting issue. The enlarged 10/20 dirty ratios are just about enough to fix the regression.
