638f85c Mark Brown 22 October 2009, 15:31:33 UTC regulator: Handle regulators without suspend mode configuration Since some regulators in the system may not support suspend mode configuration we need to allow some regulators to have a missing suspend mode configuration. Do this by requiring that disabled regulators are explicitly flagged and then skip over regulators that have no state specified. Try to avoid surprises by warning the if we could set the state but no configuration is provided. This also ensures that an all zeros configuration generates a warning rather than silently disabling the regulator.

1083c39 Mark Brown 22 October 2009, 15:31:32 UTC regulator: Factor out regulator name pretty printing Some of the regulator API functions have code to allow the machine constraints to override the device supplied name for the regulator in the constraints in order to help tie logging to supplies on the board and disambiguate when there is more than one regulator chip in the system.

I paste the new patch in mail. Please help to review again. And I also attach the mfd driver in mail. From: Haojian Zhuang <haojian.zhuang@marvell.com> Date: Thu, 8 Oct 2009 09:36:53 -0400 Subject: [PATCH] regulator: Add 88PM8607 PMIC driver This patch adds regulator drivers for Marvell 88PM8607 PMIC. This controller contains 3 DVC and 14 LDO regulators. This controller uses I2C interface.

e24a04c Mark Brown 22 September 2009, 15:47:11 UTC regulator: Implement WM831x BuckWise DC-DC convertor DVS support The BuckWise DC-DC convertors in WM831x devices support switching to a second output voltage using the logic level on one of the device pins. This is intended to allow rapid voltage switching for uses like cpufreq, replacing the I2C or SPI write used to configure the voltage of the regulator with a much faster GPIO status change. This is implemented by keeping the DVS voltage configured as the maximum voltage permitted for the regulator. If a request is made for the maximum voltage then the GPIO is used to switch to the DVS voltage, otherwise the normal ON voltage is updated and used. This follows the idiom used by most cpufreq drivers, which drop the minimum voltage as the core frequency is dropped but use a constant maximum - raising the voltage should normally be fast, but lowering it may be slower. Configuration of the DVS MFP on the device should be done externally, for example via OTP. Support is present in the hardware for monitoring the status of the transition using a second GPIO. This is not currently implemented but platform data is provided for it - the driver currently assumes that the device will be configured to transition immediately - but platform data is provided to reduce merge issues once it is.

a460978 Martin Michlmayr 19 November 2009, 16:46:32 UTC MIPS: No longer hardwire CONFIG_EMBEDDED to y There's no reason for MIPS to select EMBEDDED. 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 <tbm@cyrius.com> Cc: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/663/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> 17 December 2009, 01:57:36 UTC
6acc7d4 Dmitri Vorobiev 21 November 2009, 20:34:41 UTC MIPS: Fix and enhance built-in kernel command line Currently, MIPS kernels silently overwrite kernel command-line parameters hardcoded in CONFIG_CMDLINE by the ones received from firmware. 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.

7326c4e Wu Zhangjin 20 November 2009, 12:34:38 UTC MIPS: Tracing: Make function graph tracer work with -mmcount-ra-address That thread "MIPS: Add option to pass return address location to _mcount" from "David Daney <ddaney@caviumnetworks.com>" have added a new option -mmcount-ra-address to gcc(4.5) for MIPS to transfer the location of the return address to _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!)

29c5d34 Wu Zhangjin 20 November 2009, 12:34:34 UTC MIPS: Tracing: Add function graph tracer support for MIPS The implementation of function graph tracer for MIPS is a little different from X86. in MIPS, gcc(with -pg) only transfer the caller's return address(at) and the _mcount's return address(ra) to us. For the kernel part without -mlong-calls: move at, ra jal _mcount For the module part with -mlong-calls: lui v1, hi16bit_of_mcount addiu v1, v1, low16bit_of_mcount move at, ra jal _mcount Without -mlong-calls, if the function is a leaf, it will not save the return address(ra): ffffffff80101298 <au1k_wait>: ffffffff80101298: 67bdfff0 daddiu sp,sp,-16 ffffffff8010129c: ffbe0008 sd s8,8(sp) ffffffff801012a0: 03a0f02d move s8,sp ffffffff801012a4: 03e0082d move at,ra ffffffff801012a8: 0c042930 jal ffffffff8010a4c0 <_mcount> ffffffff801012ac: 00020021 nop so, we can hijack it directly in _mcount, but if the function is non-leaf, the return address is saved in the stack. ffffffff80133030 <copy_process>: ffffffff80133030: 67bdff50 daddiu sp,sp,-176 ffffffff80133034: ffbe00a0 sd s8,160(sp) ffffffff80133038: 03a0f02d move s8,sp ffffffff8013303c: ffbf00a8 sd ra,168(sp) ffffffff80133040: ffb70098 sd s7,152(sp) ffffffff80133044: ffb60090 sd s6,144(sp) ffffffff80133048: ffb50088 sd s5,136(sp) ffffffff8013304c: ffb40080 sd s4,128(sp) ffffffff80133050: ffb30078 sd s3,120(sp) ffffffff80133054: ffb20070 sd s2,112(sp) ffffffff80133058: ffb10068 sd s1,104(sp) ffffffff8013305c: ffb00060 sd s0,96(sp) ffffffff80133060: 03e0082d move at,ra ffffffff80133064: 0c042930 jal ffffffff8010a4c0 <_mcount> ffffffff80133068: 00020021 nop but we can not get the exact stack address(which saved ra) directly in _mcount, we need to search the content of at register in the stack space or search the "s{d,w} ra, offset(sp)" instruction in the text. '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".

538f195 Wu Zhangjin 20 November 2009, 12:34:32 UTC MIPS: Tracing: Add dynamic function tracer support With dynamic function tracer, by default, _mcount is defined as an "empty" function, it returns directly without any more action . 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 <fpcsr_pending> 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!

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.

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.

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.
