Resolve this by flushing the user mapping before copying the page on processors with a writeback VIVT cache. Note: this does have a performance impact, and so needs further consideration before being merged - can we optimize out some of the cache flushes if, eg, we know that the page isn't yet mapped?

This adds preliminary support for the SH-4A UBC to the hw-breakpoints API. Presently only a single channel is implemented, and the ptrace interface still needs to be converted. This is the first step to cleaning up the long-standing UBC mess, making the UBC more generally accessible, and finally making it SMP safe. An additional abstraction will be layered on top of this as with the perf events code to permit the various CPU families to wire up support for their own specific UBCs, as many variations exist.

Unlike MIPS, SH follows the convention that all structures in the page table (pgd_t, pmd_t, pgprot_t, etc) must be the same size. Therefore, 64-bit PTEs require 64-bit PGD entries, etc. Using 2-levels of page tables and 64-bit PTEs it is only possible to map 1GB of virtual address space. In order to map all 4GB of virtual address space we need to adopt a 3-level page table layout. This actually works out better for CONFIG_SUPERH32 because we only waste 2 PGD entries on the P1 and P2 areas (which are untranslated) instead of 256.

The memcpy() part of this is slightly subtle: while alternative instruction patching does itself use memcpy(), with the replacement block being less than 64-bytes in size the main loop of the original function doesn't get used for copying memcpy_c() over memcpy(), and hence we can safely write over its beginning. Also note that the CFI annotations are fine for both variants of each of the functions.

The problem was that pmd_offset() was returning an index of non-zero when it should have been returning 0. This non-zero offset was used to calculate the address of the pmd table to free in free_pmd_range(), which ended up trying to free an object that was not aligned on a page boundary.

This is the next big chunk of hw_breakpoint support. This decouples the SH-4A support from the core and moves it out in to its own stub, following many of the conventions established with the perf events layering. In addition to extending SH-4A support to encapsulate the remainder of the UBC channels, clock framework support for handling the UBC interface clock is added as well, allowing for dynamic clock gating. This also fixes up a regression introduced by the SIGTRAP handling that broke the ksym_tracer, to the extent that the current support works well with all of the ksym_tracer/ptrace/kgdb. The kprobes singlestep code will follow in turn. With this in place, the remaining UBC variants (SH-2A and SH-4) can now be trivially plugged in.

The LL/SC and IRQ versions were using generic stubs while the GRB version was just reimplementing what it already had for the standard cmpxchg() code. As we have optimized cmpxchg() implementations that are decoupled from the atomic code, simply falling back on the generic wrapper does the right thing. With this in place the GRB case is unaffected while the LL/SC case gets to use its optimized cmpxchg().

As SH has a very sparse IRQ map by default, all new CPUs and boards benefit from using sparseirq by default. Despite this, there are still a few stragglers (mostly due to using a fixed IRQ range for their FPGA IRQ mappings), and these still need to be converted over one by one. As these are now in the minority, and we do not want to encourage this sort of brain-damage in newer board ports, we force sparseirq on.

Now that the sh-sci earlyprintk is taken care of by the sh-sci driver directly, there's no longer any reason for having a split-out early_printk framework. sh_bios is the only other thing that uses it, so we just migrate the leftovers in to there. As it's possible to have multiple early_param()'s for the same string, there's not much point in having this split out anymore anyways, particularly since the sh_bios dependencies are still special-cased within sh-sci itself.

This follows the x86 xstate changes and implements a task_xstate slab cache that is dynamically sized to match one of hard FP/soft FP/FPU-less. This also tidies up and consolidates some of the SH-2A/SH-4 FPU fragmentation. Now fpu state restorers are commonly defined, with the init_fpu()/fpu_init() mess reworked to follow the x86 convention. The fpu_init() register initialization has been replaced by xstate setup followed by writing out to hardware via the standard restore path. As init_fpu() now performs a slab allocation a secondary lighterweight restorer is also introduced for the context switch. In the future the DSP state will be rolled in here, too. More work remains for math emulation and the SH-5 FPU, which presently uses its own special (UP-only) interfaces.

So instead of using "(%%eax)" to specify the memory address that is the semaphore, we use "(%1)" or similar. And instead of forcing the operation to always be 32-bit, we use "%z0", taking the size from the actual semaphore data structure itself. This doesn't actually matter on x86-32, but if we want to use the same inline asm for x86-64, we'll need to have the compiler generate the proper 64-bit names for the registers (%rax instead of %eax), and if we want to use a 64-bit counter too (in order to avoid the 15-bit limit on the write counter that limits concurrent users to 32767 threads), we'll need to be able to generate instructions with "q" accesses rather than "l". Since this header currently isn't enabled on x86-64, none of that matters, but we do want to use the xadd version of the semaphores rather than have to take spinlocks to do a rwsem. The mm->mmap_sem can be heavily contended when you have lots of threads all taking page faults, and the fallback rwsem code that uses a spinlock performs abysmally badly in that case.

This introduces some much overdue chainsawing of the fixed PMB support. fixed PMB was introduced initially to work around the fact that dynamic PMB mode was relatively broken, though they were never intended to converge. The main areas where there are differences are whether the system is booted in 29-bit mode or 32-bit mode, and whether legacy mappings are to be preserved. Any system booting in true 32-bit mode will not care about legacy mappings, so these are roughly decoupled. Regardless of the entry point, PMB and 32BIT are directly related as far as the kernel is concerned, so we also switch back to having one select the other. With legacy mappings iterated through and applied in the initialization path it's now possible to finally merge the two implementations and permit dynamic remapping overtop of remaining entries regardless of whether boot mappings are crafted by hand or inherited from the boot loader.

All SH-X2 and SH-X3 parts support an extended TLB mode, which has been left as experimental since support was originally merged. Now that it's had some time to stabilize and get some exposure to various platforms, we can drop it as an option and default enable it across the board. This is also good future proofing for newer parts that will drop support for the legacy TLB mode completely. This will also force 3-level page tables for all newer parts, which is necessary both for the varying page sizes and larger memories.

We have "long", we have "__s32", and we have "int". To make it work on x86-64, the types suddenly matter a lot more. It can be either a 32-bit or 64-bit signed type, and both work (with the caveat that a 32-bit counter will only have 15 bits of effective write counters, so it's limited to 32767 users). But whatever type you choose, it needs to be used consistently. This makes a new 'rwsem_counter_t', that is a 32-bit signed type. For a 64-bit type, you'd need to also update the BIAS values.

So this really does need that whole "make rwsem_count_t be 64-bit and fix the BIAS values to match" extension on top of it, but that is conceptually a totally independent issue. NOT TESTED! The original patch that this all was based on were tested by KAMEZAWA Hiroyuki, but maybe I screwed up something when I created the cleaned-up series, so caveat emptor.. Also note that it _may_ be a good idea to mark some more registers clobbered on x86-64 in the inline asms instead of saving/restoring them. They are inline functions, but they are only used in places where there are not a lot of live registers _anyway_, so doing for example the clobbers of %r8-%r11 in the asm wouldn't make the fast-path code any worse, and would make the slow-path code smaller. (Not that the slow-path really matters to that degree. Saving a few unnecessary registers is the _least_ of our problems when we hit the slow path. The instruction/cycle counting really only matters in the fast path). Signed-off-by: Linus Torvalds LKML-Reference: Signed-off-by: H.

More and more boards are going to start shipping that boot with the MMU in 32BIT mode by default. Previously we relied on the bootloader to setup PMB mappings for use by the kernel but we also need to cater for boards whose bootloaders don't set them up. If CONFIG_PMB_LEGACY is not enabled we have full control over our PMB mappings and can compress our address space. Usually, the distance between the the cached and uncached mappings of RAM is always 512MB, however we can compress the distance to be the amount of RAM on the board. pmb_init() now becomes much simpler. It no longer has to calculate any mappings, it just has to synchronise the software PMB table with the hardware. Tested on SDK7786 and SH7785LCR.

Change rwsem_count_t to a signed long, so that it is 64 bits on x86-64. This required the following changes to the assembly code: a) %z0 doesn't work on all versions of gcc! At least gcc 4.4.2 as shipped with Fedora 12 emits "ll" not "q" for 64 bits, even for integer operands. Newer gccs apparently do this correctly, but avoid this problem by using the _ASM_ macros instead of %z. b) 64 bits immediates are only allowed in "movq $imm,%reg" constructs... no others. Change some of the constraints to "e", and fix the one case where we would have had to use an invalid immediate -- in that case, we only care about the upper half anyway, so just access the upper half.

Presently 'flags' gets passed around a lot between the various ioremap helpers and implementations, which is only 32-bits. In the X2TLB case we use 64-bit pgprots which presently results in the upper 32bits being chopped off (which handily include our read/write/exec permissions). As such, we convert everything internally to using pgprot_t directly and simply convert over with pgprot_val() where needed. With this in place, transparent fixmap utilization for early ioremap works as expected.

The total number of pages to unmap factored in the mapping offset and aligned up to the next page boundary, which doesn't match the ioremap_fixed() behaviour. When ioremap_fixed() pegs a slot, the address in the mapping data already contains the offset displacement, and the size is recorded verbatim given that we're only interested in total number of pages required. As such, we need to calculate the total number from the original size in the unmap path as well. At the same time, there was also an off-by-1 problem in the fixmap index calculation which has also been corrected. Previously subsequent remaps of an identical fixmap index would trigger the pte_ERROR() in set_pte_phys(): arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506). arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506). arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506). arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506). arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506). arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506).

The FPGA also contains register information detailing the area mappings and chip select settings for all of the other blocks, so this needs to be done before we can set up anything else.

Since do_adjust_pte() modifies the page tables, we are also missing any form of locking, so we're risking corrupting the page tables.

Presently trapped I/O is only registered if it's not explicitly disabled for the platforms that select it openly. From the fault path this runs through an address lookup before figuring out that nothing matches and falls back through the error path, but we can forego the lookup completely by testing if it's been explicitly disabled. This provides a measurable speedup for things like qemu that rely on runtime disabling.

name of U300 watchdog resource This changes the bus name of the U300 watchdog from just "wdog" to "coh901327_wdog" which is used to match the corresponding driver. This makes the watchdog probe properly.

The VBR value needs to be initialized in order for any of the bios trapping to work, and as we don't do that until slightly later in the boot process, this has no real chance of working. The only reason for using this in the past was due to the fact that early serial initialization wasn't possible, but now that early sh-sci is supported by everyone, there's no longer any reason to support the sh_bios hacks in the first place. Given that, we just kill off the references completely.

Right now x86 and sh check that current is not NULL, which should never happen so remove that too. Idle task's exclusion must be performed from the core code, on top of perf_event_attr:exclude_idle.

There is no good reason for the difference, it is just an artifact of the code diverging over a couple of years. This patch renames both to simply .phandle. Note: the .node also existed in PowerPC/MicroBlaze, but the only user seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't look like the assignment between .linux_phandle and .node is significantly different enough to warrant the separate code paths unless ibm,phandle properties actually appear in Apple device trees. I think it is safe to eliminate the old .node property and use phandle everywhere. Signed-off-by: Grant Likely Acked-by: David S.

The algorithm takes into account the list of counter constraints for each event. It assigns events to counters from the most constrained, i.e., works on only one counter, to the least constrained, i.e., works on any counter. Intel Fixed counter events and the BTS special event are also handled via this algorithm which is designed to be fairly generic. The patch also updates the validation of an event to use the scheduling algorithm. This will cause early failure in perf_event_open(). The 2nd version of this patch follows the model used by PPC, by running the scheduling algorithm and the actual assignment separately. Actual assignment takes place in hw_perf_enable() whereas scheduling is implemented in hw_perf_group_sched_in() and x86_pmu_enable().

The SH7780 PCI controller supports 3 different ranges of PCI memory in addition to its PCI I/O window. In the case of 29-bit mode, only 2 memory windows are supported, while in 32-bit mode all 3 are visible. This attempts to make the resource handling completely dynamic and to permit platforms to map in as many apertures as they can handle.

Previously, the "cpu-release-addr" property contained a value referencing the boot page translation address range of 0xfffffxxx, which then indirectly accessed RAM. The "cpu-release-addr" is currently ioremapped and the secondary cores kicked. However, due to the recent change in "cpu-release-addr", it sometimes points to a memory location in low memory that cannot be ioremapped. For example on a P2020-based board with 512MB of RAM the following error occurs on bootup: <...> mpic: requesting IPIs ... __ioremap(): phys addr 0x1ffff000 is RAM lr c05df9a0 Unable to handle kernel paging request for data at address 0x00000014 Faulting instruction address: 0xc05df9b0 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=2 P2020 RDB Modules linked in: <... eventual kernel panic> Adding logic to conditionally ioremap or access memory directly resolves the issue.

The first of these fields indicates the number of cores which Linux can boot. It does not account for SMT, so it may result in cpus assigned to Linux which cannot be booted. A second patch follows that dynamically updates this for SMT. The second field just indicates that our OS is Linux, and not another OS. The system may or may not use this hint to performance tune settings for Linux.

However, that value isn't quite right for a system that supports multiple threads per core, thus permitting the firmware to assign more cores to a Linux partition than it can really cope with. This patch improves it by using the device-tree to determine the number of threads supported by the processors in order to adjust the value passed to firmware.

The event may have been scheduled out and another event may have been programmed into this counter. Thus, we need a more robust way of verifying if the counter still contains config/data related to an event. This patch adds a generation number to each counter on each cpu. Using this mechanism we can verify reliabilty whether the content of a counter corresponds to an event.

It is no longer being used in exceptional circumstances where we don't care about runtime performance, e.g. when panicing, so it makes sense improve performance is possible. With this patch I saw a 42% improvement in unwind time when calling return_address(1). Greater improvements will be seen as the number of levels unwound increases as each unwind is now cheaper. Note that insertion time has doubled but that's just the price we pay for keeping the trees balanced. However, this is a one-time cost for kernel boot/module load and so the improvements in lookup time dominate the extra time we spend keeping the trees balanced.

For this the OPB ranges address is mapped differently (base 0x00000000 -> 0xe0000000). This results in the address being identical to the lower 32bit of its physical address. This is needed for the MTD mapping to work correctly, since U-Boot will insert the physical addresses of the EBC chip selects into the EBC ranges property. This is the way its done in most other 4xx dts files as well. Additionally with a small whitespace cleanup.

Looking at the memory layout saved by "xsave", one can't say which state is represented in the memory layout. This is because if a particular state is in init state, in the xsave hdr it can be represented by bit '0'. And hence we can't really say by the xsave header wether a state is in init state or the state is not saved in the memory layout. And hence the xsave memory layout available through this regset interface uses SW usable bytes [464..511] to convey what state is represented in the memory layout. First 8 bytes of the sw_usable_bytes[464..467] will be set to OS enabled xstate mask(which is same as the 64bit mask returned by the xgetbv's xCR0). The note NT_X86_XSTATE represents the extended state information in the core file, using the above mentioned memory layout.

Previously, the "cpu-release-addr" property contained a value referencing the boot page translation address range of 0xfffffxxx, which then indirectly accessed RAM. The "cpu-release-addr" is currently ioremapped and the secondary cores kicked. However, due to the recent change in "cpu-release-addr", it sometimes points to a memory location in low memory that cannot be ioremapped. For example on a P2020-based board with 512MB of RAM the following error occurs on bootup: <...> mpic: requesting IPIs ... __ioremap(): phys addr 0x1ffff000 is RAM lr c05df9a0 Unable to handle kernel paging request for data at address 0x00000014 Faulting instruction address: 0xc05df9b0 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=2 P2020 RDB Modules linked in: <... eventual kernel panic> Adding logic to conditionally ioremap or access memory directly resolves the issue.

Trivially, a long load that follows a short store will also suffer a penalty. __downgrade_write() in rwsem incurs both penalties: the increment operation will not be able to reuse a recently-loaded rwsem value, and its result will not be reused by any recently-following rwsem operation. A comment in the code states that this is because 64-bit immediates are special and expensive; but while they are slightly special (only a single instruction allows them), they aren't expensive: a test shows that two loops, one loading a 32-bit immediate and one loading a 64-bit immediate, both take 1.5 cycles per iteration. Fix this by changing __downgrade_write to use the same add instruction on i386 and on x86_64, so that it uses the same operand size as all the other rwsem functions.

This follows the parisc change to ensure that tracehook_signal_handler() is aware of when we are single-stepping in order to ptrace_notify() appropriately. While this was implemented for 32-bit SH, sh64 neglected to make use of TIF_SINGLESTEP when it was folded in with the 32-bit code, resulting in ptrace_notify() never being called. As sh64 uses all of the other abstractions already, this simply plugs in the thread flag in the appropriate enable/disable paths and fixes up the tracehook notification accordingly. With this in place, sh64 is brought in line with what 32-bit is already doing.

Rather than being able to rely upon the CPU not accessing the DMA buffer until DMA has completed, we now must expect that the cache could be loaded with possibly stale data from the DMA buffer. Where DMA involves data being transferred to the device, we clean the cache before handing it over for DMA, otherwise we invalidate the buffer to get rid of potential writebacks. On DMA Completion, if data was transferred from the device, we invalidate the buffer to get rid of any stale speculative prefetches.

In preparation for perf-events support, ARM needs to support atomic64_t operations. v6k and above support the ldrexd and strexd instructions to do just that. This patch adds atomic64 support to the ARM architecture. v6k and above make use of new instructions whilst older cores fall back on the generic solution using spinlocks. If and when v7-M cores are supported by Linux, they will need to fall back on the spinlock implementation too.

This may lead to two processes using the same ASID (but different generation) or multiple threads of the same process using different ASIDs. This patch adds the broadcasting of the ASID rollover event to the other CPUs. To avoid a race on multiple CPUs modifying "cpu_last_asid" during the handling of the broadcast, the ASID numbering now starts at "smp_processor_id() + 1". At rollover, the cpu_last_asid will be set to NR_CPUS.

Each node size must have be a multiple of FAKE_NODE_MIN_SIZE, otherwise it is possible to get strange alignments. Because of this, the remaining memory from each node when rounded to FAKE_NODE_MIN_SIZE is consolidated into a number of "big nodes" that are bigger than the rest. The calculation of the number of big nodes is incorrect since it is using a logical AND operator when it should be multiplying the rounded-off portion of each node with N.

This requires knowledge of the system capacity when attempting to allocate nodes of a certain size: either very large nodes to benchmark scalability of code that operates on individual nodes, or very small nodes to find bugs in the VM. This patch introduces numa=fake=[MG] so it is possible to specify the size of each node to allocate. When used, nodes of the size specified will be allocated and interleaved over the set of physical nodes. FAKE_NODE_MIN_SIZE was also moved to the more-appropriate include/asm/numa_64.h.

At sufficiently large numbers of CPUs it becomes impossible to line up the CPU number with the counts. While fixing this I noticed x86 has a number of updates that we may as well pull in. On PowerPC we currently omit an interrupt completely if there is no active handler, whereas on x86 it is printed if there is a non zero count.

The patch below adds an entry for it and also adds it into the /proc/stat summaries. While here, I added performance monitoring and machine check exceptions. I found it useful to keep an eye on the PMU exception rate when using the perf tool. Since it's possible to take a completely handled machine check on a System p box it also sounds like a good idea to keep a machine check summary. The event naming matches x86 to keep gratuitous differences to a minimum.

These cases are common enough to show up as thousands of BAD interrupts a day. Tone them down by calling them spurious.

The results (in lock/unlock operations per second) are: before: 1538203 ops/sec after: 2189219 ops/sec An improvement of 42% A 32 core POWER7 improves even more: before: 1279529 ops/sec after: 2282076 ops/sec An improvement of 78% Signed-off-by: Anton Blanchard Signed-off-by: Benjamin Herrenschmidt --- arch/powerpc/include/asm/ppc-opcode.h | 14 ++++++++++++++ arch/powerpc/include/asm/spinlock.h | 7 ++++--- 2 files changed, 18 insertions(+), 3 deletions(-) (limited to 'arch') diff --git a/arch/powerpc/include/asm/ppc-opcode.h b/arch/powerpc/include/asm/ppc-opcode.h index ef9aa84cac5a..ecec76051184 100644 --- a/arch/powerpc/include/asm/ppc-opcode.h +++ b/arch/powerpc/include/asm/ppc-opcode.h @@ -24,6 +24,7 @@ #define PPC_INST_ISEL_MASK 0xfc00003e #define PPC_INST_LSWI 0x7c0004aa #define PPC_INST_LSWX 0x7c00042a +#define PPC_INST_LWARX 0x7c000029 #define PPC_INST_LWSYNC 0x7c2004ac #define PPC_INST_LXVD2X 0x7c000698 #define PPC_INST_MCRXR 0x7c000400 @@ -55,15 +56,28 @@ #define __PPC_RA(a) (((a) & 0x1f) << 16) #define __PPC_RB(b) (((b) & 0x1f) << 11) #define __PPC_RS(s) (((s) & 0x1f) << 21) +#define __PPC_RT(s) __PPC_RS(s) #define __PPC_XS(s) ((((s) & 0x1f) << 21) | (((s) & 0x20) >> 5)) #define __PPC_T_TLB(t) (((t) & 0x3) << 21) #define __PPC_WC(w) (((w) & 0x3) << 21) +/* + * Only use the larx hint bit on 64bit CPUs.

That was a long time ago and I completely dropped the ball in testing his patches across other ppc64 processors. Turns out the idea helps on other chips. Using a microbenchmark that uses a lot of threads to contend on a global pthread mutex (and therefore a global futex), POWER6 improves 8% and POWER7 improves 2%. I checked POWER5 and while I couldn't measure an improvement, there was no regression. This patch uses the lwsync patching code to replace the isyncs with lwsyncs on CPUs that support the instruction. We were marking POWER3 and RS64 as lwsync capable but in reality they treat it as a full sync (ie slow). Remove the CPU_FTR_LWSYNC bit from these CPUs so they continue to use the faster isync method.

Both the store queue API and the PMB remapping take unsigned long for their pgprot flags, which cuts off the extended protection bits. In the case of the PMB this isn't really a problem since the cache attribute bits that we care about are all in the lower 32-bits, but we do it just to be safe. The store queue remapping on the other hand depends on the extended prot bits for enabling userspace access to the mappings.

The update_checksum() function in mm/kmemleak.c calls kmemcheck_is_obj_initialised() before scanning an object. When KMEMCHECK_PARTIAL_OK is enabled, this function returns true. However, the crc32_le() reads smaller intervals (32-bit) for which kmemleak_is_obj_initialised() may be false leading to a kmemcheck warning. Note that kmemcheck_is_obj_initialized() is currently only used by kmemleak before scanning a memory location.

Rather than trusting the boot loader to do the right thing, we do a quick verification of the PMB contents to determine whether to have the kernel setup the initial mappings or whether it needs to mangle them later on instead. If we're booting from legacy mappings, the kernel will now take control of them and make them match the kernel's initial mapping configuration. This is accomplished by breaking the initialization phase out in to multiple steps: synchronization, merging, and resizing. With the recent rework, the synchronization code establishes page links for compound mappings already, so we build on top of this for promoting mappings and reclaiming unused slots. At the same time, the changes introduced for the uncached helpers also permit us to dynamically resize the uncached mapping without any particular headaches. The smallest page size is more than sufficient for mapping all of kernel text, and as we're careful not to jump to any far off locations in the setup code the mapping can safely be resized regardless of whether we are executing from it or not.

That said we don't keep track how the user enabled the breakpoints so when the user requests the dr7 value, we only translate the "enabled" status using the global enabled bits. It means that if the user enabled a breakpoint using the local enabled bit, reading back dr7 will set the global bit and clear the local one. Apps like Wine expect a full dr7 POKEUSER/PEEKUSER match for emulated softwares that implement old reverse engineering protection schemes. We fix that by keeping track of the whole dr7 value given by the user in the thread structure to drop this bug. We'll think about something more proper later.

Unfortunately, there are BIOSes, including the VMware BIOS, which report the previous mode if function 0F is queried while the screen is in a VESA mode, and of course, nothing can help a mode poked directly into the hardware. As such, the safe option is to set the mode anyway, and only query to see if we should be using mode 7 rather than mode 3. People who don't want any mode setting at all should probably use vga=0x0f04 (VIDEO_CURRENT_MODE). It's possible that should be the kernel default. Reported-by Rene Arends Signed-off-by: H.

We do this via make_coherent() by making the pages uncacheable. This used to work fine, until we allowed highmem with highpte - we now have a page table which is mapped as required, and is not available for modification via update_mmu_cache(). Ralf Beache suggested getting rid of the PTE value passed to update_mmu_cache(): On MIPS update_mmu_cache() calls __update_tlb() which walks pagetables to construct a pointer to the pte again. Passing a pte_t * is much more elegant. Maybe we might even replace the pte argument with the pte_t? Ben Herrenschmidt would also like the pte pointer for PowerPC: Passing the ptep in there is exactly what I want. I want that -instead- of the PTE value, because I have issue on some ppc cases, for I$/D$ coherency, where set_pte_at() may decide to mask out the _PAGE_EXEC. So, pass in the mapped page table pointer into update_mmu_cache(), and remove the PTE value, updating all implementations and call sites to suit.

Commit 085219f79cad89291699bd2bfb21c9fdabafe65f ("sparc32: use proper types in struct stat") Accidently changed the struct stat uid/gid members to uid_t and gid_t, but those get set to __kernel_uid32_t and __kernel_gid32_t respectively. Those are of type 'int' but the structure is meant to have 'short'. So use uid16_t and gid16_t to correct this. Reported-by: Rob Landley Signed-off-by: David S.

The thread flags happen to be the logical inverse of what the global fault mode is set to, so this works out pretty cleanly. By default the global fault mode is used, with tasks now being able to override their own settings via prctl().

We've increased this size several times when the table overflowed. But there's no good limit on the number of resources because host bridges and subtractive decode bridges can forward any number of ranges to their secondary buses. This patch reduces the table to only PCI_BRIDGE_RESOURCE_NUM (4) entries, which corresponds to the number of windows a PCI-to-PCI (3) or CardBus (4) bridge can positively decode. Any additional resources, e.g., PCI host bridge windows or subtractively-decoded regions, are kept in a list. I'd prefer a single list rather than this split table/list approach, but that requires simultaneous changes to every architecture. This approach only requires immediate changes where we set up (a) host bridges with more than four windows and (b) subtractive-decode P2P bridges, and we can incrementally change other architectures to use the list.

This means that the overhead applies even to machines which have a fairly modest amount of high memory and which therefore do not really benefit from allocating PTEs in high memory but still pay the price of the additional mapping operations. Running kernbench on a 4G box I found that with CONFIG_HIGHPTE=y but no actual highptes being allocated there was a reduction in system time used from 59.737s to 55.9s. With CONFIG_HIGHPTE=y and highmem PTEs being allocated: Average Optimal load -j 4 Run (std deviation): Elapsed Time 175.396 (0.238914) User Time 515.983 (5.85019) System Time 59.737 (1.26727) Percent CPU 263.8 (71.6796) Context Switches 39989.7 (4672.64) Sleeps 42617.7 (246.307) With CONFIG_HIGHPTE=y but with no highmem PTEs being allocated: Average Optimal load -j 4 Run (std deviation): Elapsed Time 174.278 (0.831968) User Time 515.659 (6.07012) System Time 55.9 (1.07799) Percent CPU 263.8 (71.266) Context Switches 39929.6 (4485.13) Sleeps 42583.7 (373.039) This patch allows the user to control the allocation of PTEs in highmem from the command line ("userpte=nohigh") but retains the status-quo as the default. It is possible that some simple heuristic could be developed which allows auto-tuning of this option however I don't have a sufficiently large machine available to me to perform any particularly meaningful experiments. We could probably handwave up an argument for a threshold at 16G of total RAM. Assuming 768M of lowmem we have 196608 potential lowmem PTE pages. Each page can map 2M of RAM in a PAE-enabled configuration, meaning a maximum of 384G of RAM could potentially be mapped using lowmem PTEs. Even allowing generous factor of 10 to account for other required lowmem allocations, generous slop to account for page sharing (which reduces the total amount of RAM mappable by a given number of PT pages) and other innacuracies in the estimations it would seem that even a 32G machine would not have a particularly pressing need for highmem PTEs. I think 32G could be considered to be at the upper bound of what might be sensible on a 32 bit machine (although I think in practice 64G is still supported). It's seems questionable if HIGHPTE is even a win for any amount of RAM you would sensibly run a 32 bit kernel on rather than going 64 bit.

To prevent the GPF, the NMI calls ftrace_nmi_enter() which may modify the code first, then any other NMIs will just change the text to the same content which will do no harm. The code that stop_machine called must wait for NMIs to finish while it changes each location in the kernel. That code may also change the text to what the NMI changed it to. The key is that the text will never change content while another CPU is executing it. To make the above work, the call to ftrace_nmi_enter() must also do a smp_mb() as well as atomic_inc(). But for applications like perf that require a high number of NMIs for profiling, this can have a dramatic effect on the system. Not only is it doing a full memory barrier on both nmi_enter() as well as nmi_exit() it is also modifying a global variable with an atomic operation. This kills performance on large SMP machines. Since the memory barriers are only needed when ftrace is in the process of modifying the text (which is seldom), this patch adds a "modifying_code" variable that gets set before stop machine is executed and cleared afterwards. The NMIs will check this variable and store it in a per CPU "save_modifying_code" variable that it will use to check if it needs to do the memory barriers and atomic dec on NMI exit.

The problem is that local data generates GOTOFF relocations, which means we can't relocate the data relative to the text segment. Global data, on the other hand, goes through the GOT, and can be relocated anywhere. Unfortunately, with the new decompressors, this presents a problem since they declare static data within functions, and this leads to stack overflow. Fix this by separating out the decompressor code into a separate file, and removing 'static' from BSS data in misc.c. Also, discard the .data section - this means that should we end up with read/write initialized data, the decompressor will fail to link and the problem will be obvious.

The lwsync fixup section uses .long instead of the FTR_ENTRY_OFFSET macro used by other fixups sections, and thus will generate 32-bit relocations that our module loader cannot resolve. This changes it to use the same type as other feature sections. Note however that we might want to consider using 32-bit for all the feature fixup offsets and add support for R_PPC_REL32 to module_64.c instead as that would reduce the size of the kernel image. I'll leave that as an exercise for the reader for now...

The current PMU callbacks do not distinguish between stop and release (i.e., stop + free the resource). Thus, a counter may be released, then it will be immediately re-acquired. Event scheduling will again take place with no guarantee to assign the same counter. On some processors, this may event yield to failure to assign the event back due to competion between cores. This patch is adding a new pair of callback to stop and restart a counter without actually release the underlying counter resource. On stop, the counter is stopped, its values saved and that's it. On start, the value is reloaded and counter is restarted (on x86, actual restart is delayed until perf_enable()).

NB events are events measuring L3 cache, Hypertransport traffic. They are identified by an event code >= 0xe0. They measure events on the Northbride which is shared by all cores on a package. NB events are counted on a shared set of counters. When a NB event is programmed in a counter, the data actually comes from a shared counter. Thus, access to those counters needs to be synchronized.

An IBS capability mask is introduced to test for certain IBS features. The bit mask is the same as for IBS cpuid feature flags (Fn8000_001B_EAX), but bit 0 is used to indicate the existence of IBS. The patch also changes the handling of the IbsOpCntCtl bit (periodic op counter count control). The oprofilefs file for this feature (ibs_op/dispatched_ops) will be only exposed if the feature is available, also the default for the bit is set to count clock cycles. In general, the userland can detect the availability of a feature by checking for the corresponding file in oprofilefs. If it exists, the feature also exists. This may lead to a dynamic file layout depending on the cpu type with that the userland has to deal with. Current opcontrol is compatible.

For IBS measurements it would be good to minimize memory traffic in the interrupt handler since every access pollutes the data caches. Computing a maximal period LFSR just needs shifts and ORs. The LFSR method is good enough to randomize the ops at low overhead. 16 pseudo-random bits are enough for the implementation and it doesn't matter that the pattern repeats with a fairly short cycle. It only needs to break up (hard) periodic sampling behavior. The logic was designed by Paul Drongowski.

Better statistical samples can be produced by adding a software generated random offset to the periodic op counter value with each sample. This patch adds software randomization to the IBS periodic op counter. The lower 12 bits of the 20 bit counter are randomized. IbsOpCurCnt is initialized with a 12 bit random value. There is a work around if the hw can not write to IbsOpCurCnt. Then the lower 8 bits of the 16 bit IbsOpMaxCnt [15:0] value are randomized in the range of -128 to +127 by adding/subtracting an offset to the maximum count (IbsOpMaxCnt). The linear feedback shift register (LFSR) algorithm is used for pseudo-random number generation to have low impact to the memory system.

They are identified by an event code >= 0xe00. + * They measure events on the NorthBride which is shared + * by all cores on a package. NB events are counted on a + * shared set of counters. When a NB event is programmed + * in a counter, the data actually comes from a shared + * counter. Thus, access to those counters needs to be + * synchronized. + * + * We implement the synchronization such that no two cores + * can be measuring NB events using the same counters. Thus, + * we maintain a per-NB allocation table. The available slot + * is propagated using the event_constraint structure. + * + * We provide only one choice for each NB event based on + * the fact that only NB events have restrictions. Consequently, + * if a counter is available, there is a guarantee the NB event + * will be assigned to it. If no slot is available, an empty + * constraint is returned and scheduling will eventually fail + * for this event. + * + * Note that all cores attached the same NB compete for the same + * counters to host NB events, this is why we use atomic ops. Some + * multi-chip CPUs may have more than one NB. + * + * Given that resources are allocated (cmpxchg), they must be + * eventually freed for others to use.

These initializations can be performed statically in machine init functions. The current semantics for this init() callback is ambiguous anyways, it is invoked in pxa_camera_activate(), hence at device node open, but its users use it like a generic initialization to be done at module init time (configure MFP, request GPIOs for *sensor* control).

The s390 machine check handler uses crw_handle_channel_report to handle one crw if needed. This patch replaces the semaphore with a waitqueue (to block the kernel thread) and an atomic_t (to count the number of pending requests). By this we achieve the ability to force this thread to check for a pending crw (independent on when it is triggered by the machine check handler) and wait for this action to finish.

Use asm offsets to make sure the offset defines to struct _lowcore and its layout don't get out of sync. Also add a BUILD_BUG_ON() which checks that the size of the structure is sane. And while being at it change those sites which use odd casts to access the current lowcore. These should use S390_lowcore instead.

By default on x86 all the cpus except the boot cpu have NMI masked off. This patch enables NMI on all cpus in UV system and adds an NMI handler to dump_stack on each cpu. This way if a system hangs we can NMI the machine and get a backtrace from all the cpus. Version 2: Use x86_platform driver mechanism for nmi init, per Ingo's suggestion.

They all share an identical register layout with only a few minor differences (except the PB1000) in bit functions and base addresses. This patch - adds a primitive facility to initialize and use these external registers, - replaces all occurrences of bcsr->xxx accesses with calls to the new functions (the pb1200 cascade irq handling code is special). - collects BCSR register information scattered throughout the board headers in a central place.

Some small irqmap.c files have been folded into board_setup files. Run-tested on DB1200; compile-tested on all other affected boards.

New PCMCIA socket driver for all Db/Pb1xxx boards (except Pb1000), which replaces au1000_db1x00.c and (most of) au1000_pb1x00.c. Notable improvements: - supports Db1000, DB/PB1100/1500/1550/1200. - support for carddetect and statuschange IRQs. - pcmcia socket mem/io/attr areas and irqs passed through platform resource information. - doesn't freeze system during card insertion/ejection like the one it replaces. - boardtype is automatically detected using BCSR ID register. Run-tested on the DB1200.

IRQ numbers need no longer be hidden behind a CONFIG_SOC_AU1XXX symbol: step 1 in my quest to make the Alchemy code less reliant on a hardcoded subtype. This patch also renames the GPIO irq number constants. It's really an interrupt line, NOT a GPIO number! Code which relied on certain irq numbers to have the same name across all supported cpu subtypes is changed to determine current cpu subtype at runtime; in some places this isn't possible so a "compat" symbol is used. Run-tested on DB1200.

So a generic uart tx function is provided in the alchemy headers, and the boards can provide their own prom_putchar with custom destination uart, and all in-kernel alchemy boards support early printk.

In order to achieve correct synchronization semantics, the Octeon port had defined CONFIG_WEAK_REORDERING_BEYOND_LLSC. This resulted in code that looks like: sync ll ... . . . sc ... . . sync The second SYNC was redundant, but harmless. Octeon has a SYNCW instruction that acts as a write-memory-barrier (due to an erratum in some parts two SYNCW are used). It is much faster than SYNC because it imposes ordering on the writes, but doesn't otherwise stall the execution pipeline. On Octeon, SYNC stalls execution until all preceeding writes are committed to the coherent memory system. Using: syncw;syncw ll . . . sc . . Has identical semantics to the first sequence, but is much faster. The SYNCW orders the writes, and the SC will not complete successfully until the write is committed to the coherent memory system. So at the end all preceeding writes have been committed. Since Octeon does not do speculative reads, this functions as a full barrier. The patch removes CONFIG_WEAK_REORDERING_BEYOND_LLSC, and substitutes SYNCW for SYNC in write-memory-barriers.

Enable Suspend support Enable Run Time PM support o Enable SM7XX Video Driver Disable the buggy 2d acceleration o Enable CONFIG_OPROFILE as module o Use GZIP instead of LZMA, which need less decompression time o Enable more USB devices support o Enable initrd support(needed by gNewsense) o Enable more crypto support Signed-off-by: Wu Zhangjin Cc: linux-mips@linux-mips.org Cc: yanh@lemote.com Cc: huhb@lemote.com Cc: zhangfx@lemote.com Patchwork: http://patchwork.linux-mips.org/patch/830/ Signed-off-by: Ralf Baechle --- arch/mips/configs/lemote2f_defconfig | 964 ++++++++++++++++++++++++----------- 1 file changed, 670 insertions(+), 294 deletions(-) (limited to 'arch') diff --git a/arch/mips/configs/lemote2f_defconfig b/arch/mips/configs/lemote2f_defconfig index b71a0a4fb95f..4caa0e0fee81 100644 --- a/arch/mips/configs/lemote2f_defconfig +++ b/arch/mips/configs/lemote2f_defconfig @@ -1,7 +1,7 @@ #

The upper two bits of EntryLo{0,1} are RI and XI when the feature is enabled in the PageGrain register. SmartMIPS only covers 32-bit systems. Cavium Octeon+ extends this to 64-bit systems by continuing to place the RI and XI bits in the top of EntryLo even when EntryLo is 64-bits wide. Because we need to carry the RI and XI bits in the PTE, the layout of the PTE is changed. There is a two instruction overhead in the TLB refill hot path to get the EntryLo bits into the proper position. Also the TLB load exception has to probe the TLB to check if RI or XI caused the exception. Also of note is that the layout of the PTE bits is done at compile and runtime rather than statically. In the 32-bit case this allows for the same number of PFN bits as before the patch as the _PAGE_HUGE is not supported in 32-bit kernels (we have _PAGE_NO_EXEC and _PAGE_NO_READ instead of _PAGE_READ and _PAGE_HUGE). The patch is tested on Cavium Octeon+, but should also work on 32-bit systems with the Smart-MIPS ASE.

The current locking mechanism uses a ll/sc sequence to release a spinlock. This is slower than a wmb() followed by a store to unlock. The branching forward to .subsection 2 on sc failure slows down the contended case. So we get rid of that part too. Since we are now working on naturally aligned u16 values, we can get rid of a masking operation as the LHU already does the right thing. The ANDI are reversed for better scheduling on multi-issue CPUs On a 12 CPU 750MHz Octeon cn5750 this patch improves ipv4 UDP packet forwarding rates from 3.58*10^6 PPS to 3.99*10^6 PPS, or about 11%.

The complicated solution is to reserve all address range that potencially could cause such aliases. But with the PCI spec limiting port allocations for devices to a maximum of 256 bytes 16MB of port address space already is way more than one would ever expect to be used so we just reduce the port space to 16MB.

On Alchemy the PCMCIA area lies at the end of the chips 36bit system bus area. Currently, addresses at the far end of the 32bit area are assumed to belong to the PCMCIA area and fixed up to the real 36bit address before being passed to ioremap(). A previous commit enabled 64 bit physical size for the resource datatype on Alchemy and this allows to use the correct 36bit addresses when registering the PCMCIA sockets. This patch removes the 32-to-36bit address fixup and registers the Alchemy demo board pcmcia socket with the correct 36bit physical addresses. Tested on DB1200, with a CF card (ide-cs driver) and a 3c589 PCMCIA ethernet card.

I think this is the approach Ben Herrenschmidt suggested long ago: http://marc.info/?l=linux-kernel&m=119733290624544&w=2 This allows us to remove the IORESOURCE_PCI_FIXED hack from pcibios_fixup_device_resources(), which converts bus addresses to CPU addresses. IORESOURCE_PCI_FIXED denotes resources that can't be moved; it has nothing to do with converting bus to CPU addresses.

Due to ISA restrictions ColdFire needs different rt_sigreturn trampoline. And due to ColdFire FP registers being 8-bytes instead of 12-bytes on m68k, sigcontext and fpregset structures should be updated. Regarding the sc_fpstate[16+6*8] field, it would've been enough 16 bytes to store ColdFire's FP state. To accomodate GLIBC's libSegFault it would'be been enough 6*8 bytes (room for the 6 non-call-clobbered FP registers). I set it to 16+6*8 to provide some extra space for any future changes in the ColdFire FPU.
