2011-11-29ASoC: Move SigmaDSP firmware loader to ASoCLars-Peter Clausen
It has been pointed out previously, that the firmware subsystem is not the right place for the SigmaDSP firmware loader. Furthermore the SigmaDSP is currently only used in audio products and we are aiming for better integration into the ASoC framework in the future, with support for ALSA controls for firmware parameters and support dynamic power management as well. So the natural choice for the SigmaDSP firmware loader is the ASoC subsystem.

2011-04-30driver: Google EFI SMIMike Waychison
The "gsmi" driver bridges userland with firmware specific routines for accessing hardware. Currently, this driver only supports NVRAM and eventlog information. Deprecated functions have been removed from the driver, though their op-codes are left in place so that they are not re-used. This driver works by trampolining into the firmware via the smi_command outlined in the FADT table. Three protocols are used due to various limitations over time, but all are included herein. This driver should only ever load on Google boards, identified by either a "Google, Inc." board vendor string in DMI, or "GOOGLE" in the OEM strings of the FADT ACPI table. This logic happens in gsmi_system_valid().

2011-02-25firmware: Basic dmi-sysfs supportMike Waychison
Introduce a new module "dmi-sysfs" that exports the broken out entries of the DMI table through sysfs. Entries are enumerated via dmi_walk() on module load, and are populated as kobjects rooted at /sys/firmware/dmi/entries. Entries are named "<type>-<instance>", where: <type> : is the type of the entry, and <instance> : is the ordinal count within the DMI table of that entry type. This instance is used in lieu the DMI entry's handle as no assurances are made by the kernel that handles are unique. All entries export the following attributes: length : The length of the formatted portion of the entry handle : The handle given to this entry by the firmware raw : The raw bytes of the entire entry, including the formatted portion, the unformatted (strings) portion, and the two terminating nul characters. type : The DMI entry type instance : The ordinal instance of this entry given its type. position : The position ordinal of the entry within the table in its entirety. Entries in dmi-sysfs are kobject backed members called "struct dmi_sysfs_entry" and belong to dmi_kset. They are threaded through entry_list (protected by entry_list_lock) so that we can find them at cleanup time.

2011-01-21kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

Not all iscsi drivers support ibft. For drivers like be2iscsi that do not but are bootable through a vendor firmware specific format/process this patch moves the sysfs interface from the ibft code to a lib module. This then allows userspace tools to search for iscsi boot info in a common place and in a common format. ibft iscsi boot info is exported in the same place as it was before: /sys/firmware/ibft. vendor/fw boot info gets export in /sys/firmware/iscsi_bootX, where X is the scsi host number of the HBA. Underneath these parent dirs, the target, ethernet, and initiator dirs are the same as they were before.

2008-07-08sysfs: add /sys/firmware/memmapBernhard Walle
This patch adds /sys/firmware/memmap interface that represents the BIOS (or Firmware) provided memory map. The tree looks like: /sys/firmware/memmap/0/start (hex number) end (hex number) type (string) ... /1/start end type With the following shell snippet one can print the memory map in the same form the kernel prints itself when booting on x86 (the E820 map). --------- 8< -------------------------- #!/bin/sh cd /sys/firmware/memmap for dir in * ; do start=$(cat $dir/start) end=$(cat $dir/end) type=$(cat $dir/type) printf "%016x-%016x (%s)\n" $start $[ $end +1] "$type" done --------- >8 -------------------------- That patch only provides the needed interface: 1. The sysfs interface. 2. The structure and enumeration definition. 3. The function firmware_map_add() and firmware_map_add_early() that should be called from architecture code (E820/EFI, for example) to add the contents to the interface. If the kernel is compiled without CONFIG_FIRMWARE_MEMMAP, the interface does nothing without cluttering the architecture-specific code with #ifdef's. The purpose of the new interface is kexec: While /proc/iomem represents the *used* memory map (e.g. modified via kernel parameters like 'memmap' and 'mem'), the /sys/firmware/memmap tree represents the unmodified memory map provided via the firmware. So kexec can: - use the original memory map for rebooting, - use the /proc/iomem for setting up the ELF core headers for kdump case that should only represent the memory of the system. The patch has been tested on i386 and x86_64.

2008-04-20Firmware: add iSCSI iBFT SupportKonrad Rzeszutek
Add /sysfs/firmware/ibft/[initiator|targetX|ethernetX] directories along with text properties which export the the iSCSI Boot Firmware Table (iBFT) structure. What is iSCSI Boot Firmware Table? It is a mechanism for the iSCSI tools to extract from the machine NICs the iSCSI connection information so that they can automagically mount the iSCSI share/target. Currently the iSCSI information is hard-coded in the initrd. The /sysfs entries are read-only one-name-and-value fields. The usual set of data exposed is: # for a in `find /sys/firmware/ibft/ -type f -print`; do echo -n "$a: "; cat $a; done /sys/firmware/ibft/target0/target-name: iqn.2007.com.intel-sbx44:storage-10gb /sys/firmware/ibft/target0/nic-assoc: 0 /sys/firmware/ibft/target0/chap-type: 0 /sys/firmware/ibft/target0/lun: 00000000 /sys/firmware/ibft/target0/port: 3260 /sys/firmware/ibft/target0/ip-addr: 192.168.79.116 /sys/firmware/ibft/target0/flags: 3 /sys/firmware/ibft/target0/index: 0 /sys/firmware/ibft/ethernet0/mac: 00:11:25:9d:8b:01 /sys/firmware/ibft/ethernet0/vlan: 0 /sys/firmware/ibft/ethernet0/gateway: 192.168.79.254 /sys/firmware/ibft/ethernet0/origin: 0 /sys/firmware/ibft/ethernet0/subnet-mask: 255.255.252.0 /sys/firmware/ibft/ethernet0/ip-addr: 192.168.77.41 /sys/firmware/ibft/ethernet0/flags: 7 /sys/firmware/ibft/ethernet0/index: 0 /sys/firmware/ibft/initiator/initiator-name: iqn.2007-07.com:konrad.initiator /sys/firmware/ibft/initiator/flags: 3 /sys/firmware/ibft/initiator/index: 0 For full details of the IBFT structure please take a look at: ftp://ftp.software.ibm.com/systems/support/system_x_pdf/ibm_iscsi_boot_firmware_table_v1.02.pdf [akpm@linux-foundation.org: fix build] Signed-off-by: Konrad Rzeszutek <konradr@linux.vnet.ibm.com> Cc: Mike Christie <michaelc@cs.wisc.edu> Cc: Peter Jones <pjones@redhat.com> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-11DMI-based module autoloadingLennart Poettering
The patch below adds DMI/SMBIOS based module autoloading to the Linux kernel. The idea is to load laptop drivers automatically (and other drivers which cannot be autoloaded otherwise), based on the DMI system identification information of the BIOS. Right now most distros manually try to load all available laptop drivers on bootup in the hope that at least one of them loads successfully. This patch does away with all that, and uses udev to automatically load matching drivers on the right machines. Basically the patch just exports the DMI information that has been parsed by the kernel anyway to userspace via a sysfs device /sys/class/dmi/id and makes sure that proper modalias attributes are available. Besides adding the "modalias" attribute it also adds attributes for a few other DMI fields which might be useful for writing udev rules. This patch is not an attempt to export the entire DMI/SMBIOS data to userspace. We already have "dmidecode" which parses the complete DMI info from userspace. The purpose of this patch is machine model identification and good udev integration. To take advantage of DMI based module autoloading, a driver should export one or more MODULE_ALIAS fields similar to these: MODULE_ALIAS("dmi:*:svnMICRO-STARINT'LCO.,LTD:pnMS-1013:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*"); MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1058:pvr0581:rvnMSI:rnMS-1058:*:ct10:*"); MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1412:*:rvnMSI:rnMS-1412:*:cvnMICRO-STARINT'LCO.,LTD:ct10:*"); MODULE_ALIAS("dmi:*:svnNOTEBOOK:pnSAM2000:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*"); These lines are specific to my msi-laptop.c driver. They are basically just a concatenation of a few carefully selected DMI fields with all potentially bad characters stripped. Besides laptop drivers, modules like "hdaps", the i2c modules and the hwmon modules are good candidates for "dmi:" MODULE_ALIAS lines. Besides merely exporting the DMI data via sysfs the patch adds support for a few more DMI fields. Especially the CHASSIS fields are very useful to identify different laptop modules. The patch also adds working MODULE_ALIAS lines to my msi-laptop.c driver. I'd like to thank Kay Sievers for helping me to clean up this patch for posting it on lkml. Patch is against Linus' current GIT HEAD. Should probably apply to older kernels as well without modification.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
