[PATCH] ARM64: disable DCACHE_WORD_ACCESS in big endian case

by Victor Kamensky

If DCACHE_WORD_ACCESS is enabled big endian image failed to boot. commit 7bc13fd33adb9536bd73965cd46bbf7377df097c "arm64: dcache: select DCACHE_WORD_ACCESS for little-endian CPUs" enabled this setting for both big endian and little endian cpus. And code in commit itself seems to be endian agnostic, however other, i.e C, code that sits under DCACHE_WORD_ACCESS seems to be not endian agnostic, I could not figure out where though. Solution is to enable DCACHE_WORD_ACCESS only if little endian mode is enabled (default).

[PATCH v2] ARM: uprobes need icache flush after xol write

by Victor Kamensky

Hi Guys, This second version of patch to flush icache and dcache after uprobes xol write to make written instruction available in icache. Please see [1] for initial discussion. This patch follows Russell's suggestion, and function that does cache flush after xol slot instruction write is shared/reused with similar one implemented already for ptrace code. In order to reuse common implementation but to avoid vma use by xol_get_insn_slot I split flush_ptrace_access into two functions. Where first part retrieves all required conditions from vma and places them into flags variable and then calls second function which is common code. Also I had to change xol_get_insn_slot function to map page into kernel explicitly within function without use of copy_to_page helper because ARM cache flush code need both kernel address through which instruction write happens and virtual address of user-land process where instruction will end up. I hope this call back is universal enough so other CPU could implement their cache invalidation/sync after uprobes xol instruction write logic based on provided parameters. I've tested it on Arndale board with my SystemTap test case that had cache problem before. Disassemble of flush_uprobe_xol_access in case of Arndale shows that compiler does good job and optimizes out all flags check effectively leaving on this cpu call to flush_icache_alias or call to v7_coherent_user_range (__cpuc_coherent_kern_range). Also tested basic user-level debugging. Wondering on what ARM boards/cpus could we test cache_is_vivt() and cache_is_vipt_aliasing cases ... Just to summarize, please note on [1] there were couple other suggestions: Oleg suggested to use flush_icache_user_range but Russell argument was that meaning of the function is lost and on ARM it is not implemented in such way that it could address the issue anyway. Please see [2] for details. Note it would has vma problem use or not, that should be hacked. Dave Martin suggested to use flush_icache_range, which is effectively better way to call __cpuc_coherent_[kern|user]_range(s,e), that was originally suggested. But Russell explained that it won't be enough in case of user-land process pages and variety of cache types have to be covered. Note for kernel pages it would be OK and it is used in multiple places like kprobes, modules, etc. Thanks, Victor [1] http://lists.infradead.org/pipermail/linux-arm-kernel/2014-April/245595.html http://lists.infradead.org/pipermail/linux-arm-kernel/2014-April/245427.html [2] http://lists.infradead.org/pipermail/linux-arm-kernel/2014-April/245605.html Victor Kamensky (1): ARM: uprobes need icache flush after xol write arch/arm/include/asm/cacheflush.h | 2 ++ arch/arm/kernel/uprobes.c | 6 ++++++ arch/arm/mm/flush.c | 41 +++++++++++++++++++++++++++++++++------ include/linux/uprobes.h | 3 +++ kernel/events/uprobes.c | 33 +++++++++++++++++++++++++------ 5 files changed, 73 insertions(+), 12 deletions(-) -- 1.8.1.4

Probably best just to apply this, then - someone can always reimplement if they need to.

kdump for Linaro? Or any ARM Linux?

by Andy Nicholas

Hello, hopefully this is the correct mailing list for this question: I'm working on a derivative of the mainline Linux 3.8 kernel and I'm trying to enable ARM kdump functionality to collect crashdumps when we have kernel problems. But, there's some kind of unresolved issue in arch/arm/mm/ioremap.c which prevents /proc/vmcore from being able to function properly. I checked and this appears to still be in kernel.org Linux 3.13. The target is a normal, recent ARMv7 chip. Has this issue been addressed in any version of Linaro's kernel? Or, is there a work-around? If not, how does a crashdump file get generated when/if the Linaro kernel crashes or a driver faults? >> WARNING: at arch/arm/mm/ioremap.c:244 __arm_ioremap_pfn_caller+0x1d8/0x1f0() >> Modules linked in: >> [<c0016660>] (unwind_backtrace+0x0/0x138) from [<c0020480>] (warn_slowpath_common+0x4c/0x64) >> [<c0020480>] (warn_slowpath_common+0x4c/0x64) from [<c00204b4>] (warn_slowpath_null+0x1c/0x24) >> [<c00204b4>] (warn_slowpath_null+0x1c/0x24) from [<c0018e9c>] (__arm_ioremap_pfn_caller+0x1d8/0x1f0) >> [<c0018e9c>] (__arm_ioremap_pfn_caller+0x1d8/0x1f0) from [<c0018f20>] (__arm_ioremap_caller+0x54/0x5c) >> [<c0018f20>] (__arm_ioremap_caller+0x54/0x5c) from [<c0018c58>] (__arm_ioremap+0x18/0x1c) >> [<c0018c58>] (__arm_ioremap+0x18/0x1c) from [<c00168fc>] (copy_oldmem_page+0x34/0xc0) >> [<c00168fc>] (copy_oldmem_page+0x34/0xc0) from [<c010350c>] (read_from_oldmem+0xb8/0xe4) >> [<c010350c>] (read_from_oldmem+0xb8/0xe4) from [<c05c37e0>] (parse_crash_elf32_headers+0x184/0x43c) >> [<c05c37e0>] (parse_crash_elf32_headers+0x184/0x43c) from [<c05c3b64>] (vmcore_init+0xcc/0x198) >> [<c05c3b64>] (vmcore_init+0xcc/0x198) from [<c000863c>] (do_one_initcall+0x34/0x184) >> [<c000863c>] (do_one_initcall+0x34/0x184) from [<c05b28dc>] (kernel_init_freeable+0xfc/0x1c8) >> [<c05b28dc>] (kernel_init_freeable+0xfc/0x1c8) from [<c04326d4>] (kernel_init+0x8/0xe4) >> [<c04326d4>] (kernel_init+0x8/0xe4) from [<c000ec58>] (ret_from_fork+0x14/0x3c) >> >> arch/arm/mm/ioremap.c:244 >> /* >> * Don't allow RAM to be mapped - this causes problems with ARMv6+ >> */ >> if (WARN_ON(pfn_valid(pfn))) >> return NULL; Thanks in advance for any help. -andy

[PATCH] Input: ads7877: Remove bitrotted comment

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> While searching for users of spi_async() I found a reference in the ad7877 driver to using it to initiate data transfer from the interrupt handler. However there is no code for this, instead the interrupt handler is a threaded handler and uses spi_sync() instead. Remove the bitrotted comment, though in actual fact the use case mentioned is a great use for spi_async() since it would cut down on latency handling the interrupt by saving us a context switch before we start SPI. This was previously implemented, it was removed in commit b534422b2d11 (Input: ad7877 - switch to using threaded IRQ) for code complexity reasons. It may be better to revert that commit instead.

[3.11.y.z extended stable] Patch "tick-common: Fix wrong check in tick_check_replacement()" has been added to staging queue

by Luis Henriques

This is a note to let you know that I have just added a patch titled tick-common: Fix wrong check in tick_check_replacement() to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/lin… If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ >From 39bbe41d9e322c01c6c67cf71763dd66d9172a94 Mon Sep 17 00:00:00 2001 From: Viresh Kumar <viresh.kumar(a)linaro.org> Date: Tue, 15 Apr 2014 10:54:37 +0530 Subject: tick-common: Fix wrong check in tick_check_replacement() commit 521c42990e9d561ed5ed9f501f07639d0512b3c9 upstream. tick_check_replacement() returns if a replacement of clock_event_device is possible or not. It does this as the first check: if (tick_check_percpu(curdev, newdev, smp_processor_id())) return false; Thats wrong. tick_check_percpu() returns true when the device is useable. Check for false instead.

[PATCH] cpufreq: Make linux-pm@vger.kernel.org official mailing list

by Viresh Kumar

There have been confusion all the time about which mailing list to follow for cpufreq activities, linux-pm(a)vger.kernel.org or cpufreq(a)vger.kernel.org. As Maintainers always wanted people to send patches to linux-pm(a)vger.kernel.org and kernel source asked them to use cpufreq(a)vger.kernel.org. Lets make linux-pm(a)vger.kernel.org the official mailing list for cpufreq stuff and remove all references of cpufreq(a)vger.kernel.org from kernel source. Later, we can remove the list as well from vger.kernel.org.
