From 1b93b3c3e94be2605759735a89fc935ba5f58dcf Mon Sep 17 00:00:00 2001 From: Wu Zhangjin Date: Wed, 14 Oct 2009 18:12:16 +0800 Subject: MIPS: Add support for GZIP / BZIP2 / LZMA compressed kernel images This patch helps to generate smaller kernel images for linux-MIPS, Here is the effect when using lzma: $ ls -sh vmlinux 7.1M vmlinux $ ls -sh vmlinuz 1.5M vmlinuz Have tested the 32bit kernel on Qemu/Malta and 64bit kernel on FuLoong Mini PC. both of them work well. and also, tested by Alexander Clouter on an AR7 based Linksys WAG54Gv2, and by Manuel Lauss on an Alchemy board. This -v2 version incorporate the feedback from Ralf, and add the following changes: 1. add .ecoff, .bin, .erec format support 2. only enable it and the debug source code for the machines we tested 3. a dozen of fixups and cleanups and if you want to enable it for your board, please try to select SYS_SUPPORTS_ZBOOT for it, and if the board have an 16550 compatible uart, you can select SYS_SUPPORTS_ZBOOT_UART16550 directly. and then sending the relative patches to Ralf.

The Octeon SOC has two types of Ethernet ports, each type with its own driver. However, the PHYs for all the ports are controlled by a common MDIO bus. Because the mdio driver is not associated with a particular driver, but is instead a system level resource, we create s stand-alone driver for it. As for the driver, we put the register definitions in arch/mips/include/asm/octeon where most of the other Octeon register definitions live. This is a platform driver with the platform device for "mdio-octeon" being registered in the platform startup code. Signed-off-by: David Daney Acked-by: David S.

The Octeon MGMT Ethernet ports are present in some members of the Octeon SOC family (cn52XX and cn56XX have them). The mdio bus connected to the MGMT PHYs is shared with the main octeon-ethernet driver, we force it to be loaded first by calling octeon_mdiobus_force_mod_depencency. The platform devices for the MGMT Ethernet ports are added in arch/mips/cavium-octeon/octeon-platform.c, and the register definitions for the ports live in arch/mips/include/asm/octeon/ along with their ilk. Although it currently is the only driver in drivers/net/octeon, the directory was created looking forward to the day that octeon-ethernet will move there from its current home in drivers/staging.

Processors that support the mips64r2 ISA can in four instructions convert a shifted PGD pointer stored in the upper bits of c0_context into a usable pointer. By doing this we save a memory load and associated potential cache miss in the TLB exception handlers. Since the upper bits of c0_context were holding the CPU number, we move this to the upper bits of c0_xcontext which doesn't have enough bits to hold the PGD pointer, but has plenty for the CPU number.

The built-in Loongson 2E/2F northbridge in is bonito64-compatible but not identical with it.

On SMP systems, the collection of statistics can cause cache line bouncing in the lines associated with the counters. Also there are races incrementing the counters on multiple CPUs. To fix both problems, we collect the statistics in per-CPU variables, and add them up in the debugfs read operation. As a test I ran the LTP float_bessel test on a 12 CPU Octeon system. Without CONFIG_DEBUG_FS : 2602 seconds. With CONFIG_DEBUG_FS: 2640 seconds. With non-cpu-local atomic statistics: 14569 seconds.

The PCI-X controller has a programming interface similiar to the the FPGA northbridge used on Loongson 2E. The main differences between Loongson 2E and Loongson 2F include: 1. Loongson 2F has an extra address window configuration module, which is used to map CPU address space to DDR or PCI address space, or map the PCI-DMA address space to DDR or LIO address space. 2. Loongson 2F supports 8 levels of software configurable CPu frequency which can be configured in the LOONGSON_CHIPCFG0 register. The coming cpufreq and standby support are based on this feature. Loongson.h abstracts the modules and corresponding methods are abstracted. Add other Loongson-2F-specific source code including gcc 4.4 support, PCI memory space, PCI IO space, DMA address.

2009 13:39:12 +0800 Subject: MIPS: Loongson 2F: Cleanup the #if clauses This patch adds two new kernel options: CPU_SUPPORTS_CPUFREQ and CPU_SUPPORTS_ADDRWINCFG to describe the new features of Loongons 2F and replaces the several ugly #if clauses by them. These two options will be utilized by the future loongson revisions and related drivers such as the coming Loongson 2F CPUFreq driver.

These interrupts are board-specific, Yeeloong2F use the keyboard interrupt and SCI interrupt, but LingLoong and Fuloong2F use the interrupts connected to the processors directly. and BTW: some old LingLoong and FuLoong2F have no such interrupts connected, so, there is no way to wake them up from suspend mode. and therefore, please do not enable the kernel support for them.

For YeeLoong 2F and Mengloong 2F setup the keyboard interrupt as the wakeup interrupt. The new Fuloong 2F and LingLoong 2F have a button to directly send an interrupt to the CPU so there is no need to setup an interrupt.

This patch add the MIPS specific _mcount support for static function tracing. by default, ftrace_trace_function is initialized as ftrace_stub(an empty function), so, the default _mcount will introduce very little overhead. after enabling ftrace in user-space, it will jump to a real tracing function and do static function tracing for us. and -ffunction-sections is incompatible with -pg, so, disable it when ftracer is enabled.

When enabling it in user-space, it will jump to a real tracing function(ftrace_caller), and do the real job for us. Differ from the static function tracer, dynamic function tracer provides two functions ftrace_make_call()/ftrace_make_nop() to enable/disable the tracing of some indicated kernel functions(set_ftrace_filter). In the -v4 version, the implementation of this support is basically the same as X86 version does: _mcount is implemented as an empty function and ftrace_caller is implemented as a real tracing function respectively. But in this version, to support module tracing with the help of -mlong-calls in arch/mips/Makefile: MODFLAGS += -mlong-calls. The stuff becomes a little more complex. We need to cope with two different type of calling to _mcount. For the kernel part, the calling to _mcount(result of "objdump -hdr vmlinux"). is like this: 108: 03e0082d move at,ra 10c: 0c000000 jal 0 10c: R_MIPS_26 _mcount 10c: R_MIPS_NONE *ABS* 10c: R_MIPS_NONE *ABS* 110: 00020021 nop For the module with -mlong-calls, it looks like this: c: 3c030000 lui v1,0x0 c: R_MIPS_HI16 _mcount c: R_MIPS_NONE *ABS* c: R_MIPS_NONE *ABS* 10: 64630000 daddiu v1,v1,0 10: R_MIPS_LO16 _mcount 10: R_MIPS_NONE *ABS* 10: R_MIPS_NONE *ABS* 14: 03e0082d move at,ra 18: 0060f809 jalr v1 In the kernel version, there is only one "_mcount" string for every kernel function, so, we just need to match this one in mcount_regex of scripts/recordmcount.pl, but in the module version, we need to choose one of the two to match. Herein, I choose the first one with "R_MIPS_HI16 _mcount". and In the kernel verion, without module tracing support, we just need to replace "jal _mcount" by "jal ftrace_caller" to do real tracing, and filter the tracing of some kernel functions via replacing it by a nop instruction. but as we have described before, the instruction "jal ftrace_caller" only left 32bit length for the address of ftrace_caller, it will fail when calling from the module space. so, herein, we must replace something else. the basic idea is loading the address of ftrace_caller to v1 via changing these two instructions: lui v1,0x0 addiu v1,v1,0 If we want to enable the tracing, we need to replace the above instructions to: lui v1, HI_16BIT_ftrace_caller addiu v1, v1, LOW_16BIT_ftrace_caller If we want to stop the tracing of the indicated kernel functions, we just need to replace the "jalr v1" to a nop instruction. but we need to replace two instructions and encode the above two instructions oursevles. Is there a simpler solution? Yes! Here it is, in this version, we put _mcount and ftrace_caller together, which means the address of _mcount and ftrace_caller is the same: _mcount: ftrace_caller: j ftrace_stub nop ...(do real tracing here)... ftrace_stub: jr ra move ra, at By default, the kernel functions call _mcount, and then jump to ftrace_stub and return. and when we want to do real tracing, we just need to remove that "j ftrace_stub", and it will run through the two "nop" instructions and then do the real tracing job. what about filtering job? we just need to do this: lui v1, hi_16bit_of_mcount <--> b 1f (0x10000004) addiu v1, v1, low_16bit_of_mcount move at, ra jalr v1 nop 1f: (rec->ip + 12) In linux-mips64, there will be some local symbols, whose name are prefixed by $L, which need to be filtered. thanks goes to Steven for writing the mips64-specific function_regex. In a conclusion, with RISC, things becomes easier with such a "stupid" trick, RISC is something like K.I.S.S, and also, there are lots of "simple" tricks in the whole ftrace support, thanks goes to Steven and the other folks for providing such a wonderful tracing framework!

'Cause we can not prove there is only a match in the stack space, so, we search the text instead. as we can see, if the first instruction above "move at, ra" is not a store instruction, there should be a leaf function, so we hijack the at register directly via putting &return_to_handler into it, otherwise, we search the "s{d,w} ra, offset(sp)" instruction to get the stack offset, and then the stack address. we use the above copy_process() as an example, we at last find "ffbf00a8", 0xa8 is the stack offset, we plus it with s8(fp), that is the stack address, we hijack the content via writing the &return_to_handler in. If with -mlong-calls, since there are two more instructions above "move at, ra", so, we can move the pointer to the position above "lui v1, hi16bit_of_mcount".

Benefit from this new feature, function graph tracer on MIPS will be easier and safer to hijack the return address of the kernel function, which will save some overhead and make the whole thing more reliable. In this patch, at first, try to enable the option -mmcount-ra-address in arch/mips/Makefile with cc-option, if gcc support it, it will be enabled, otherwise, no side effect. and then, we need to support this new option of gcc 4.5 and also support the old gcc versions. with _mcount in the old gcc versions, it's not easy to get the location of return address(tracing: add function graph tracer support for MIPS), so, we do it in a C function: ftrace_get_parent_addr(ftrace.c), but with -mmcount-ra-address, only several instructions need to get what we want, so, I put into asm(mcount.S). and also, as the $12(t0) is used by -mmcount-ra-address for transferring the localtion of return address to _mcount, we need to save it into the stack and restore it when enabled dynamic function tracer, 'Cause we have called "ftrace_call" before "ftrace_graph_caller", which may destroy $12(t0). (Thanks to David for providing that -mcount-ra-address and giving the idea of KBUILD_MCOUNT_RA_ADDRESS, both of them have made the whole thing more beautiful!)

2009 19:05:24 +0800 Subject: MIPS: Yeeloong 2F: Add LID open event as the wakeup event Yeeloong 2F netbook has an KB3310B embedded controller to manage the LID action. When the LID is closed or opened a SCI interrupt is sent out and the corresponding event is saved to an EC register for later query. Allow the LID open interrupt to wake the processor from wait mode if it is in the suspend mode.

Therefore, using firmware remains the only reliable method to transfer the command-line parameters, which is not always desirable or convenient, and the CONFIG_CMDLINE option is thereby effectively rendered useless. This patch fixes the problem described above and introduces a more flexible scheme of handling the kernel command line, in a manner identical to what is currently used for x86. The default behavior, i.e. when CONFIG_CMDLINE_BOOL is not defined, retains the existing semantics, and firmware command-line arguments override the hardcoded ones.

In fact, EMBEDDED makes MIPS more awkward to deal with because it makes it different to the majority of architectures for no good reason. [Ralf: Historically disabling EMBEDDED had hid essential options for many MIPS platforms such as serial console and forced crap like VGA support or power managment enabled for platforms where those don't make any sense. The name of the option is also _very_ missleading so many users don't select it even where is was required for a functioning kernel.] Signed-off-by: Martin Michlmayr Cc: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/663/ Signed-off-by: Ralf Baechle diff --git a/arch/mips/Kconfig b/arch/mips/Kconfig index f374cca..9541171 100644 --- a/arch/mips/Kconfig +++ b/arch/mips/Kconfig @@ -10,8 +10,6 @@ config MIPS select HAVE_DYNAMIC_FTRACE select HAVE_FTRACE_MCOUNT_RECORD select HAVE_FUNCTION_GRAPH_TRACER - # Horrible source of confusion.
