Linux-2.6.12-rc2 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!

MIPS: Use ARCH_USE_BUILTIN_BSWAP. ARCH_USE_BUILTIN_BSWAP will use __builtin_bswap16(), __builtin_bswap32() and __builtin_bswap64() where available. This allows better instruction scheduling. On pre-R2 processors it will result in 32 bit and 64 bit swapping being performed in a call to a __bswapsi2() rsp. __bswapdi2() functions, so we add these, too. For a 4.2 kernel with GCC 4.9 this yields the following kernel sizes: text data bss dec hex filename 3996071 155804 88992 4240867 40b5e3 vmlinux ip22 baseline 3985687 159900 88992 4234579 409d53 vmlinux ip22 + bswap patch 6913157 378552 251024 7542733 7317cd vmlinux ip27 baseline 6878581 378552 251024 7508157 7290bd vmlinux ip27 + bswap patch 5773777 268752 187424 6229953 5f0fc1 vmlinux malta baseline 5773401 268752 187424 6229577 5f0e49 vmlinux malta + bswap patch Presumably the code size improvments yield better cache hit rate thus better performance compensating for the extra function call but this will still need to be benchmarked.

Add HAVE_OPROFILE Linus: On the per-architecture side, I do think it would be better to *not* have internal architecture knowledge in a generic file, and as such a line like depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32 really shouldn't exist in a file like kernel/Kconfig.instrumentation. It would be much better to do depends on ARCH_SUPPORTS_KPROBES in that generic file, and then architectures that do support it would just have a bool ARCH_SUPPORTS_KPROBES default y in *their* architecture files. That would seem to be much more logical, and is readable both for arch maintainers *and* for people who have no clue - and don't care - about which architecture is supposed to support which interface... Changelog: Actually, I know I gave this as the magic incantation, but now that I see it, I realize that I should have told you to just use config ARCH_SUPPORTS_KPROBES def_bool y instead, which is a bit denser. We seem to use both kinds of syntax for these things, but this is really what "def_bool" is there for... Changelog : - Moving to HAVE_*. - Add AVR32 oprofile.

[MIPS] kgdb: add arch support for the kernel's kgdb core The new kgdb architecture specific handler registers and unregisters dynamically for exceptions depending on when you configure a kgdb I/O driver. Aside from initializing the exceptions earlier in the boot process, kgdb should have no impact on a device when it is compiled in so long as an I/O module is not configured for use. There have been quite a number of contributors during the existence of this patch (see arch/mips/kernel/kgdb.c). Most recently Jason re-wrote the mips kgdb logic to use the die notification handlers.

MIPS: Tracing: Add static function tracer support for MIPS If -pg of gcc is enabled with CONFIG_FUNCTION_TRACER=y. a calling to _mcount will be inserted into each kernel function. so, there is a possibility to trace the kernel functions in _mcount. 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.

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!

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".

mm: expose arch_mmap_rnd when available When an architecture fully supports randomizing the ELF load location, a per-arch mmap_rnd() function is used to find a randomized mmap base. In preparation for randomizing the location of ET_DYN binaries separately from mmap, this renames and exports these functions as arch_mmap_rnd(). Additionally introduces CONFIG_ARCH_HAS_ELF_RANDOMIZE for describing this feature on architectures that support it (which is a superset of ARCH_BINFMT_ELF_RANDOMIZE_PIE, since s390 already supports a separated ET_DYN ASLR from mmap ASLR without the ARCH_BINFMT_ELF_RANDOMIZE_PIE logic).

Since Loongson-2/3 are both 64-bit general- purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.

Make most arch asm/module.h files use asm-generic/module.h Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela, ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version into asm-generic/module.h for all arches bar MIPS. Also, use the generic definition mod_arch_specific where possible. To this end, I've defined three new config bools: (*) HAVE_MOD_ARCH_SPECIFIC Arches define this if they don't want to use the empty generic mod_arch_specific struct. (*) MODULES_USE_ELF_RELA Arches define this if their modules can contain RELA records. This causes the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be defined by the arch rather than have the core emit an error message. (*) MODULES_USE_ELF_REL Arches define this if their modules can contain REL records. This causes the Elf_Rel mapping to be emitted and allows apply_relocate() to be defined by the arch rather than have the core emit an error message. Note that it is possible to allow both REL and RELA records: m68k and mips are two arches that do this. With this, some arch asm/module.h files can be deleted entirely and replaced with a generic-y marker in the arch Kbuild file. Additionally, I have removed the bits from m32r and score that handle the unsupported type of relocation record as that's now handled centrally.

MIPS: VDSO: Add implementations of gettimeofday() and clock_gettime() Add user-mode implementations of gettimeofday() and clock_gettime() to the VDSO. This is currently usable with 2 clocksources: the CP0 count register, which is accessible to user-mode via RDHWR on R2 and later cores, or the MIPS Global Interrupt Controller (GIC) timer, which provides a "user-mode visible" section containing a mirror of its counter registers. This section must be mapped into user memory, which is done below the VDSO data page. When a supported clocksource is not in use, the VDSO functions will return -ENOSYS, which causes libc to fall back on the standard syscall path. When support for neither of these clocksources is compiled into the kernel at all, the VDSO still provides clock_gettime(), as the coarse realtime/monotonic clocks can still be implemented. However, gettimeofday() is not provided in this case as nothing can be done without a suitable clocksource. This causes the symbol lookup to fail in libc and it will then always use the standard syscall path. This patch includes a workaround for a bug in QEMU which results in RDHWR on the CP0 count register always returning a constant (incorrect) value. A fix for this has been submitted, and the workaround can be removed after the fix has been in stable releases for a reasonable amount of time. A simple performance test which calls gettimeofday() 1000 times in a loop and calculates the average execution time gives the following results on a Malta + I6400 (running at 20MHz): - Syscall: ~31000 ns - VDSO (GIC): ~15000 ns - VDSO (CP0): ~9500 ns [markos.chandras@imgtec.com: - Minor code re-arrangements in order for mappings to be made in the order they appear to the process' address space. - Move do_{monotonic, realtime} outside of the MIPS_CLOCK_VSYSCALL ifdef - Use gic_get_usm_range so we can do the GIC mapping in the arch/mips/kernel/vdso instead of the GIC irqchip driver] Signed-off-by: Alex Smith <alex.smith@imgtec.com> Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Cc: linux-kernel@vger.kernel.org Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/11338/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Previously the r4k timer was initialized regardless, but it's useless with the "wait" instruction. So long story short: I need either the on-chip 32kHz timer OR the r4k timer if the 32kHz one is unusable, but not both, and r4k timer is useless when au1k_idle is in use. The current in-kernel Alchemy boards all work with the 32kHz timer, so I'm not against removing R4K_LIB symbols. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Manuel Lauss <manuel.lauss@gmail.com> writes: I introduced it as a fallback because early revisions of Alchemy hardware we shipped had a non-functional 32kHz timer and had to rely on the r4k timer instead. Previously the r4k timer was initialized regardless, but it's useless with the "wait" instruction. So long story short: I need either the on-chip 32kHz timer OR the r4k timer if the 32kHz one is unusable, but not both, and r4k timer is useless when au1k_idle is in use. The current in-kernel Alchemy boards all work with the 32kHz timer, so I'm not against removing R4K_LIB symbols. Signed-off-by: Steven J.

MIPS: Alchemy: clock framework integration of onchip clocks This patch introduces common clock framework integration for all configurable on-chip clocks on Alchemy chips: - 2 or 3 PLLs which generate integer multiples of the root rate 12MHz, - 6 dividers which take one of the 3 PLLs as input and divide their rate by either multiples of 2 or 1 (Au1300). - another bank of up to 6 muxes which take either one of the 6 above dividers or one of the PLLs directly and divide their rate further by 1, 2, 3 or 4. - a few other sources which are used by onchip peripherals and are informational. This implementation will take the clock tree as it was set up by boot firmware: all in-kernel boards should continue to work without having to set up the clock tree in board code. CLK_IGNORE_DISABLED will be removed once all drivers have been converted.

Linux-2.6.12-rc2 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!

MIPS: BCM47xx: Move NVRAM driver to the drivers/firmware/ After Broadcom switched from MIPS to ARM for their home routers we need to have NVRAM driver in some common place (not arch/mips/). As explained in Kconfig, this driver is responsible for parsing SoC configuration data that is passed to the kernel in flash from the bootloader firmware called "CFE". We were thinking about putting it in bus directory, however there are two possible buses for MIPS: drivers/ssb/ and drivers/bcma/. So this won't fit there and this is why I would like to move this driver to the drivers/firmware/.

[MIPS] R4000/R4400 errata workarounds This is the gereric part of R4000/R4400 errata workarounds. They include compiler and assembler support as well as some source code modifications to address the problems with some combinations of multiply/divide+shift instructions as well as the daddi and daddiu instructions. Changes included are as follows: 1. New Kconfig options to select workarounds by platforms as necessary. 2. Arch top-level Makefile to pass necessary options to the compiler; also incompatible configurations are detected (-mno-sym32 unsupported as horribly intrusive for little gain). 3. Bug detection updated and shuffled -- the multiply/divide+shift problem is lethal enough that if not worked around it makes the kernel crash in time_init() because of a division by zero; the daddiu erratum might also trigger early potentially, though I have not observed it. On the other hand the daddi detection code requires the exception subsystem to have been initialised (and is there mainly for information). 4. r4k_daddiu_bug() added so that the existence of the erratum can be queried by code at the run time as necessary; useful for generated code like TLB fault and copy/clear page handlers. 5. __udelay() updated as it uses multiplication in inline assembly. Note that -mdaddi requires modified toolchain (which has been maintained by myself and available from my site for ~4years now -- versions covered are GCC 2.95.4 - 4.1.2 and binutils from 2.13 onwards). The -mfix-r4000 and -mfix-r4400 have been standard for a while though. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAP If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT. The changes in this commit were done using: $ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/' Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This both saves the probing for systems where the amount of memory is fixed, and will simplify the bringup of later Ingenic SoCs where the memory controller register layout differs.

MIPS: Kconfig: Enable microMIPS support for Malta Add missing microMIPS support to Malta. Currently the kernel only enables support for the instruction set for the SEAD-3 board despite the fact processor features have nothing to do with the board a processor is installed in. In this case there is no way to run microMIPS software in a fully supported way under Linux on QEMU. QEMU supports the emulation of a Malta board, but does not emulate SEAD-3. Linux supports running microMIPS code on a SEAD-3 board, but hardcodes such support to off on an emulated Malta board even if the processor selected has the microMIPS instruction set implemented. Adding support for the SEAD-3 to QEMU is a major project. Flipping a bit in the kernel that shouldn't have been cleared in the first place is a trivial effort. Thus the answer is plain...

[MIPS] Add basic SMARTMIPS ASE support This patch adds trivial support for SMARTMIPS extension. This extension is currently implemented by 4KS[CD] CPUs. Basically it saves/restores ACX register, which is part of the SMARTMIPS ASE, when needed. This patch does *not* add any support for Smartmips MMU features. Futhermore this patch does not add explicit support for 4KS[CD] CPUs since they are respectively mips32 and mips32r2 compliant. So with the current processor configuration, a platform that has such CPUs needs to select both configs: CPU_HAS_SMARTMIPS SYS_HAS_CPU_MIPS32_R[12] This is due to the processor configuration which is mixing up all the architecture variants and the processor types. The drawback of this, is that we currently pass '-march=mips32' option to gcc when building a kernel instead of '-march=4ksc' for 4KSC case. This can lead to a kernel image a little bit bigger than required. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Since we can't rely upon Malta boards running a bootloader capable of handling devictrees & filling in the required information, a piece of shim code (malta_dt_shim) is added to consume the (e)memsize variables provided as part of the bootloader environment (or on the kernel command line) then generate the DT memory node using the provided values.

Linux-2.6.12-rc2 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!

MIPS: Cavium: Add EDAC support. Drivers for EDAC on Cavium. Supported subsystems are: o CPU primary caches. These are parity protected only, so only error reporting. o Second level cache - ECC protected, provides SECDED. o Memory: ECC / SECDEC if used with suitable DRAM modules. The driver will will only initialize if ECC is enabled on a system so is safe to run on non-ECC memory. o PCI: Parity error reporting Since it is very hard to test this sort of code the implementation is very conservative and uses polling where possible for now.

EDAC: Cleanup atomic_scrub mess So first of all, this atomic_scrub() function's naming is bad. It looks like an atomic_t helper. Change it to edac_atomic_scrub(). The bigger problem is that this function is arch-specific and every new arch which doesn't necessarily need that functionality still needs to define it, otherwise EDAC doesn't compile. So instead of doing that and including arch-specific headers, have each arch define an EDAC_ATOMIC_SCRUB symbol which can be used in edac_mc.c for ifdeffery. Much cleaner. And we already are doing this with another symbol - EDAC_SUPPORT. This is also much cleaner than having CONFIG_EDAC enumerate all the arches which need/have EDAC support and drivers. This way I can kill the useless edac.h header in tile too.

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.

MIPS: Add initial support for the Atheros AR71XX/AR724X/AR931X SoCs This patch adds initial support for various Atheros SoCs based on the MIPS 24Kc core. The following models are supported at the moment: - AR7130 - AR7141 - AR7161 - AR9130 - AR9132 - AR7240 - AR7241 - AR7242 The current patch contains minimal support only, but the resulting kernel can boot into user-space with using of an initramfs image on various boards which are using these SoCs. Support for more built-in devices and individual boards will be implemented in further patches.

MIPS: Lantiq: add SoC specific code for XWAY family Add support for the Lantiq XWAY family of Mips24KEc SoCs. * Danube (PSB50702) * Twinpass (PSB4000) * AR9 (PSB50802) * Amazon SE (PSB5061) The Amazon SE is a lightweight SoC and has no PCI as well as a different clock. We split the code out into seperate files to handle this. The GPIO pins on the SoCs are multi function and there are several bits we can use to configure the pins. To be as compatible as possible to GPIOLIB we add a function int lq_gpio_request(unsigned int pin, unsigned int alt0, unsigned int alt1, unsigned int dir, const char *name); which lets you configure the 2 "alternate function" bits. This way drivers like PCI can make use of GPIOLIB without a cubersome wrapper. The PLL code inside arch/mips/lantiq/xway/clk-xway.c is voodoo to me. It was taken from a 2.4.20 source tree and was never really changed by me since then.

[PATCH] LOG2: Implement a general integer log2 facility in the kernel This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

MIPS: VDSO: Add implementations of gettimeofday() and clock_gettime() Add user-mode implementations of gettimeofday() and clock_gettime() to the VDSO. This is currently usable with 2 clocksources: the CP0 count register, which is accessible to user-mode via RDHWR on R2 and later cores, or the MIPS Global Interrupt Controller (GIC) timer, which provides a "user-mode visible" section containing a mirror of its counter registers. This section must be mapped into user memory, which is done below the VDSO data page. When a supported clocksource is not in use, the VDSO functions will return -ENOSYS, which causes libc to fall back on the standard syscall path. When support for neither of these clocksources is compiled into the kernel at all, the VDSO still provides clock_gettime(), as the coarse realtime/monotonic clocks can still be implemented. However, gettimeofday() is not provided in this case as nothing can be done without a suitable clocksource. This causes the symbol lookup to fail in libc and it will then always use the standard syscall path. This patch includes a workaround for a bug in QEMU which results in RDHWR on the CP0 count register always returning a constant (incorrect) value. A fix for this has been submitted, and the workaround can be removed after the fix has been in stable releases for a reasonable amount of time. A simple performance test which calls gettimeofday() 1000 times in a loop and calculates the average execution time gives the following results on a Malta + I6400 (running at 20MHz): - Syscall: ~31000 ns - VDSO (GIC): ~15000 ns - VDSO (CP0): ~9500 ns [markos.chandras@imgtec.com: - Minor code re-arrangements in order for mappings to be made in the order they appear to the process' address space. - Move do_{monotonic, realtime} outside of the MIPS_CLOCK_VSYSCALL ifdef - Use gic_get_usm_range so we can do the GIC mapping in the arch/mips/kernel/vdso instead of the GIC irqchip driver] Signed-off-by: Alex Smith <alex.smith@imgtec.com> Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Cc: linux-kernel@vger.kernel.org Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/11338/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

gpiolib: allow user-selection This patch adds functionality to the gpio-lib subsystem to make it possible to enable the gpio-lib code even if the architecture code didn't request to get it built in. The archtitecture code does still need to implement the gpiolib accessor functions in its asm/gpio.h file. This patch adds the implementations for x86 and PPC. With these changes it is possible to run generic GPIO expansion cards on every architecture that implements the trivial wrapper functions. Support for more architectures can easily be added.

MIPS: Kconfig: Rename several firmware related config symbols. With the upcoming merge of the ARC architecture there is a small likelyhood of conflicting use for the CONFIG_ARC config symbol. Rename it to CONFIG_FW_ARC. Also rename CONFIG_ARC32 to CONFIG_FW_ARC32, CONFIG_ARC64 to CONFIG_FW_ARC64.

Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAP If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT.

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.

MIPS: Require O32 FP64 support for MIPS64 with O32 compat MIPS32r6 code requires FP64 (ie. FR=1) support. Building a kernel with support for MIPS32r6 binaries but without support for O32 with FP64 is therefore a problem which can lead to incorrectly executed userland. CONFIG_MIPS_O32_FP64_SUPPORT is already selected when the kernel is configured for MIPS32r6, but not when the kernel is configured for MIPS64r6 with O32 compat support. Select CONFIG_MIPS_O32_FP64_SUPPORT in such configurations to prevent building kernels which execute MIPS32r6 userland incorrectly.

Linux-2.6.12-rc2 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.

MIPS: Octeon: Set OHCI and EHCI MMIO byte order to match CPU The Octeon OHCI is now supported by the ohci-platform driver, and USB_OCTEON_OHCI is marked as deprecated. However, it is currently still necessary to enable it in order to select USB_OHCI_BIG_ENDIAN_MMIO. Make CPU_CAVIUM_OCTEON select that as well, so that USB_OCTEON_OHCI is really obsolete. The old ohci-octeon and ehci-octeon drivers also only enabled big-endian MMIO in case the CPU was big-endian. Make the selections of USB_EHCI_BIG_ENDIAN_MMIO and USB_OHCI_BIG_ENDIAN_MMIO conditional, to match this.

MIPS: Loongson: Add CPU_LOONGSON2F_WORKAROUNDS As documented in the Loongson 2F User Manual [2, 3], the old Loongson2F series (2F01 / 2F02) have the NOP & JUMP issues which requires workarounds in the kernel and binutils. This issue has been rectified in Loongson 2F series 2F03 so no workarounds needed. Now that the workarounds [1] adding the the -mfix-loongson2f-nop and -mfix-loongson2f-jump options have been comitted to the binutils the CVS repository), we can add the workarounds in the kernel. The workarounds have no significant side effect on the system but may decrease performance so we control them through a a new CPU_LOONGSON2F_WORKAROUNDS config option allowing the users to only enable it as necessary.

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.

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.

MIPS: Put PGD in C0_CONTEXT for 64-bit R2 processors. 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.

MIPS: Fix possible build error with transparent hugepages enabled If CONFIG_TRANSPARENT_HUGEPAGE is enabled, but CONFIG_HUGETLB_PAGE is not, it is possible to end up with a configuration that fails to build with the following error: include/linux/huge_mm.h:125:2: error: #error "hugepages can't be allocated by the buddy allocator" This is due to CONFIG_FORCE_MAX_ZONEORDER defaulting to 11. It already has ranges that change the valid values when HUGETLB_PAGE is enabled, but this is not done for TRANSPARENT_HUGEPAGE.

MIPS: Fix build error when SMP is used without GIC commit 7a50e4688dabb8005df39b2b992d76629b8af8aa upstream. The MIPS_GIC_IPI should only be selected when MIPS_GIC is also selected, otherwise it results in a compile error. smp-gic.c uses some functions from include/linux/irqchip/mips-gic.h like plat_ipi_call_int_xlate() which are only added to the header file when MIPS_GIC is set. The Lantiq SoC does not use the GIC, but supports SMP. The calls top the functions from smp-gic.c are already protected by some #ifdefs The first part of this was introduced in commit 72e20142b2bf ("MIPS: Move GIC IPI functions out of smp-cmp.c") Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Cc: Paul Burton <paul.burton@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/12774/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

MIPS: Deprecate CONFIG_MIPS_CMP CONFIG_MIPS_CPS is a better option for systems where it is supported, which as far as I am aware should be all systems where CONFIG_MIPS_CMP could provide any value (ie. where there are multiple cores for YAMON to bring up). This option is therefore deprecated, and marked as such.

MIPS: Fix build error when SMP is used without GIC commit 7a50e4688dabb8005df39b2b992d76629b8af8aa upstream. The MIPS_GIC_IPI should only be selected when MIPS_GIC is also selected, otherwise it results in a compile error. smp-gic.c uses some functions from include/linux/irqchip/mips-gic.h like plat_ipi_call_int_xlate() which are only added to the header file when MIPS_GIC is set. The Lantiq SoC does not use the GIC, but supports SMP.

MIPS: pm-cps: add PM state entry code for CPS systems This patch adds code to generate entry & exit code for various low power states available on systems based around the MIPS Coherent Processing System architecture (ie. those with a Coherence Manager, Global Interrupt Controller & for >=CM2 a Cluster Power Controller). States supported are: - Non-coherent wait. This state first leaves the coherent domain and then executes a regular MIPS wait instruction. Power savings are found from the elimination of coherency interventions between the core and any other coherent requestors in the system. - Clock gated. This state leaves the coherent domain and then gates the clock input to the core. This removes all dynamic power from the core but leaves the core at the mercy of another to restart its clock. Register state is preserved, but the core can not service interrupts whilst its clock is gated. - Power gated. This deepest state removes all power input to the core. All register state is lost and the core will restart execution from its BEV when another core powers it back up. Because register state is lost this state requires cooperation with the CONFIG_MIPS_CPS SMP implementation in order for the core to exit the state successfully. The code will detect which states are available on the current system during boot & generate the entry/exit code for those states. This will be used by cpuidle & hotplug implementations.

MIPS: Add generic CM probe & access code The kernel currently only probes for a MIPS Coherence Manager in the Malta interrupt code in order to detect & enable the GIC. However CM is not Malta-specific, so this should really be more generic. This patch introduces some non-Malta-specific code which probes for a CM and performs some basic initialisation. A new header, with temporarily duplicated register definitions, is introduced in order to: 1) Allow the new definitions to be correct with regards to the CM documentation, as many of those in gcmpregs.h aren't. 2) Allow switching away from the REG() macro used via a few layers of nested macros in order to access registers in gcmpregs.h. This patch instead introduced accessor functions akin to the {read,write}_c0_* functions used for cop0 registers. 3) Allow users of the CM to be migrated one by one. 4) Switch from the name 'GCMP' to 'CM' since the Coherence Manager is what this code is actually dealing with.

Basically it saves/restores ACX register, which is part of the SMARTMIPS ASE, when needed. This patch does *not* add any support for Smartmips MMU features. Futhermore this patch does not add explicit support for 4KS[CD] CPUs since they are respectively mips32 and mips32r2 compliant. So with the current processor configuration, a platform that has such CPUs needs to select both configs: CPU_HAS_SMARTMIPS SYS_HAS_CPU_MIPS32_R[12] This is due to the processor configuration which is mixing up all the architecture variants and the processor types. The drawback of this, is that we currently pass '-march=mips32' option to gcc when building a kernel instead of '-march=4ksc' for 4KSC case.

The drawback of this, is that we currently pass '-march=mips32' option to gcc when building a kernel instead of '-march=4ksc' for 4KSC case. This can lead to a kernel image a little bit bigger than required. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

MIPS: Basic MSA context switching support This patch adds support for context switching the MSA vector registers. These 128 bit vector registers are aliased with the FP registers - an FP register accesses the least significant bits of the vector register with which it is aliased (ie. the register with the same index). Due to both this & the requirement that the scalar FPU must be 64-bit (FR=1) if enabled at the same time as MSA the kernel will enable MSA & scalar FP at the same time for tasks which use MSA. If we restore the MSA vector context then we might as well enable the scalar FPU since the reason it was left disabled was to allow for lazy FP context restoring - but we just restored the FP context as it's a subset of the vector context. If we restore the FP context and have previously used MSA then we have to restore the whole vector context anyway (see comment in enable_restore_fp_context for details) so similarly we might as well enable MSA. Thus if a task does not use MSA then it will continue to behave as without this patch - the scalar FP context will be saved & restored as usual. But if a task executes an MSA instruction then it will save & restore the vector context forever more.

[MIPS] R4000/R4400 errata workarounds This is the gereric part of R4000/R4400 errata workarounds. They include compiler and assembler support as well as some source code modifications to address the problems with some combinations of multiply/divide+shift instructions as well as the daddi and daddiu instructions. Changes included are as follows: 1. New Kconfig options to select workarounds by platforms as necessary. 2. Arch top-level Makefile to pass necessary options to the compiler; also incompatible configurations are detected (-mno-sym32 unsupported as horribly intrusive for little gain). 3. Bug detection updated and shuffled -- the multiply/divide+shift problem is lethal enough that if not worked around it makes the kernel crash in time_init() because of a division by zero; the daddiu erratum might also trigger early potentially, though I have not observed it. On the other hand the daddi detection code requires the exception subsystem to have been initialised (and is there mainly for information). 4. r4k_daddiu_bug() added so that the existence of the erratum can be queried by code at the run time as necessary; useful for generated code like TLB fault and copy/clear page handlers. 5. __udelay() updated as it uses multiplication in inline assembly. Note that -mdaddi requires modified toolchain (which has been maintained by myself and available from my site for ~4years now -- versions covered are GCC 2.95.4 - 4.1.2 and binutils from 2.13 onwards). The -mfix-r4000 and -mfix-r4400 have been standard for a while though. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

[PATCH] Configurable NODES_SHIFT Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.

MIPS: add support for hardware performance events (skeleton) This patch provides the skeleton of the HW perf event support. To enable this feature, we can not choose the SMTC kernel; Oprofile should be disabled; kernel performance events be selected. Then we can enable it in Kernel type menu. Oprofile for MIPS platforms initializes irq at arch init time. Currently we do not change this logic to allow PMU reservation. If a platform has EIC, we can use the irq base and perf counter irq offset defines for the interrupt controller in specific init_hw_perf_events(). Based on this skeleton patch, the 3 different kinds of MIPS PMU, namely, mipsxx/loongson2/rm9000, can be supported by adding corresponding lower level C files at the bottom. The suggested names of these files are perf_event_mipsxx.c/perf_event_loongson2.c/perf_event_rm9000.c. So, for example, we can do this by adding "#include perf_event_mipsxx.c" at the bottom of perf_event.c. In addition, PMUs with 64bit counters are also considered in this patch.

The suggested names of these files are perf_event_mipsxx.c/perf_event_loongson2.c/perf_event_rm9000.c. So, for example, we can do this by adding "#include perf_event_mipsxx.c" at the bottom of perf_event.c. In addition, PMUs with 64bit counters are also considered in this patch.

MIPS: Coherent Processing System SMP implementation This patch introduces a new SMP implementation for systems implementing the MIPS Coherent Processing System architecture. The kernel will make use of the Coherence Manager, Cluster Power Controller & Global Interrupt Controller in order to detect, bring up & make use of other cores in the system. SMTC is not supported, so only a single TC per VPE in the system is used. That is, this option enables an SMVP style setup but across multiple cores.

MIPS: Allow 24Hz timer frequency A boundary exists beyond which the timer frequency becomes high enough that timer interrupts saturate the system and either cause it to slow to a crawl or stop functioning entirely. Where that boundary lies depends upon a number of factors such as the overhead of each interrupt and the overall speed of the CPU, but correlates strongly with the clock frequency at which the CPU runs. When running on emulators during bringup or debug of a CPU that clock frequency is very low, which results in the boundary at which the timer frequency becomes unsustainable being very low. The current minimum of 48Hz pushes against boundary in certain situations in current systems. Allow the kernel to be configured for a 24Hz timer frequency in order to avoid problems on such slow running systems.

kexec: split kexec_load syscall from kexec core code There are two kexec load syscalls, kexec_load another and kexec_file_load. kexec_file_load has been splited as kernel/kexec_file.c. In this patch I split kexec_load syscall code to kernel/kexec.c. And add a new kconfig option KEXEC_CORE, so we can disable kexec_load and use kexec_file_load only, or vice verse. The original requirement is from Ted Ts'o, he want kexec kernel signature being checked with CONFIG_KEXEC_VERIFY_SIG enabled. But kexec-tools use kexec_load syscall can bypass the checking. Vivek Goyal proposed to create a common kconfig option so user can compile in only one syscall for loading kexec kernel. KEXEC/KEXEC_FILE selects KEXEC_CORE so that old config files still work. Because there's general code need CONFIG_KEXEC_CORE, so I updated all the architecture Kconfig with a new option KEXEC_CORE, and let KEXEC selects KEXEC_CORE in arch Kconfig. Also updated general kernel code with to kexec_load syscall. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Dave Young <dyoung@redhat.com> Cc: Eric W.

MIPS: Support for 64-bit FP with O32 binaries CPUs implementing MIPS32 R2 may include a 64-bit FPU, just as MIPS64 CPUs do. In order to preserve backwards compatibility a 64-bit FPU will act like a 32-bit FPU (by accessing doubles from the least significant 32 bits of an even-odd pair of FP registers) when the Status.FR bit is zero, again just like a mips64 CPU. The standard O32 ABI is defined expecting a 32-bit FPU, however recent toolchains support use of a 64-bit FPU from an O32 MIPS32 executable. When an ELF executable is built to use a 64-bit FPU a new flag (EF_MIPS_FP64) is set in the ELF header. With this patch the kernel will check the EF_MIPS_FP64 flag when executing an O32 binary, and set Status.FR accordingly. The addition of O32 64-bit FP support lessens the opportunity for optimisation in the FPU emulator, so a CONFIG_MIPS_O32_FP64_SUPPORT Kconfig option is introduced to allow this support to be disabled for those that don't require it. Inspired by an earlier patch by Leonid Yegoshin, but implemented more cleanly & correctly.

MIPS: mark O32+FP64 experimental for now Commit 597ce1723e0f "MIPS: Support for 64-bit FP with O32 binaries" introduced support for setting Status.FR=1 for O32 binaries with the EF_MIPS_FP64 ELF header flag set. Whilst this flag is currently supported by binutils it does introduce an ABI break within userland. Objects built with EF_MIPS_FP64 cannot be safely linked with those built without it since code in either object may assume behaviour specific to a value of FR. More recently there has been discussion around avoiding further fragmentation of the O32 ABI whilst still allowing the use of FR=1 and features such as MSA which depend upon it. Details of the plan to allow this are still being worked on, and whilst the kernel will need the ability to handle FR=1 with O32 tasks it is unclear what else it may need to provide to a userland which seeks to avoid another ABI break. In order to prevent the proliferation of userland which may rely upon the current EF_MIPS_FP64 behaviour this patch marks the kernel support for it experimental & disables it by default. Under current proposals it is likely that this support can simply be enabled again later, but possibly after the introduction of further interfaces with userland and support for the MIPS R5 UFR feature.

container freezer: implement freezer cgroup subsystem This patch implements a new freezer subsystem in the control groups framework. It provides a way to stop and resume execution of all tasks in a cgroup by writing in the cgroup filesystem. The freezer subsystem in the container filesystem defines a file named freezer.state. Writing "FROZEN" to the state file will freeze all tasks in the cgroup. Subsequently writing "RUNNING" will unfreeze the tasks in the cgroup. Reading will return the current state. * Examples of usage : # mkdir /containers/freezer # mount -t cgroup -ofreezer freezer /containers # mkdir /containers/0 # echo $some_pid > /containers/0/tasks to get status of the freezer subsystem : # cat /containers/0/freezer.state RUNNING to freeze all tasks in the container : # echo FROZEN > /containers/0/freezer.state # cat /containers/0/freezer.state FREEZING # cat /containers/0/freezer.state FROZEN to unfreeze all tasks in the container : # echo RUNNING > /containers/0/freezer.state # cat /containers/0/freezer.state RUNNING This is the basic mechanism which should do the right thing for user space task in a simple scenario. It's important to note that freezing can be incomplete. In that case we return EBUSY. This means that some tasks in the cgroup are busy doing something that prevents us from completely freezing the cgroup at this time. After EBUSY, the cgroup will remain partially frozen -- reflected by freezer.state reporting "FREEZING" when read. The state will remain "FREEZING" until one of these things happens: 1) Userspace cancels the freezing operation by writing "RUNNING" to the freezer.state file 2) Userspace retries the freezing operation by writing "FROZEN" to the freezer.state file (writing "FREEZING" is not legal and returns EIO) 3) The tasks that blocked the cgroup from entering the "FROZEN" state disappear from the cgroup's set of tasks.

Linux-2.6.12-rc2 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!

MIPS: Add basic CPUFreq options. This patch adds basic options for MIPS CPUFreq support. Since the cp0 timer's frequency is based on the processor clockrate it can not be used with CPUFReq; an additional external timer is required.

[NET]: add a top-level Networking menu to *config Create a new top-level menu named "Networking" thus moving net related options and protocol selection way from the drivers menu and up on the top-level where they belong. To implement this all architectures has to source "net/Kconfig" before drivers/*/Kconfig in their Kconfig file. This change has been implemented for all architectures. Device drivers for ordinary NIC's are still to be found in the Device Drivers section, but Bluetooth, IrDA and ax25 are located with their corresponding menu entries under the new networking menu item.
