[PATCH] ARM: topology: Make it clear that all CPUs need to be described

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> The ARMv8 code will reject topologies that omit some CPUs (and it's not clear that it's ever sensible to do so). Update the binding document to make this clear. Since we're reformatting the text also fix incorrect grammar in the final "Any other configuration..." section by removing "consider".

[GIT PULL LSK] New Gator version to match latest DS-5 release

by Jon Medhurst (Tixy)

Hi Mark, Alex ARM have released a new version of DS-5 and I have a pull request below to update the version of gator in LSK. Note, the last time gator was pulled into LSK it got done as a rebase rather than a merge commit so the conflict resolution will look messy. Basically, after the merge the contents of drivers/gator/ and tools/gator/daemon/ should be identical to my lsk-3.10-gator branch. (When I tried merging with "-X theirs", it didn't seem to quite work, so watch out for that.) Thanks - Tixy The following changes since commit dffc698f098d93044e28f4f97206eca6373c7cdf: Merge in gator version 5.17 (2013-12-19 09:36:46 +0000) are available in the git repository at: git://git.linaro.org/landing-teams/working/arm/kernel.git lsk-3.10-gator for you to fetch changes up to 03925e64e3aff28a204a61f4b833aabe6aface2c: Merge in gator version 5.18 (2014-04-10 12:45:17 +0100) ---------------------------------------------------------------- Jon Medhurst (4): gator: Version 5.18 gator-daemon: Fix compilation error: 'sa_family_t' does not name a type gator: Add config for building the module in-tree Merge in gator version 5.18 drivers/gator/Kconfig | 10 +- drivers/gator/gator.h | 13 +- drivers/gator/gator_annotate.c | 2 +- drivers/gator/gator_annotate_kernel.c | 8 +- drivers/gator/gator_backtrace.c | 48 +- drivers/gator/gator_buffer.c | 168 +++++ .../gator/{gator_pack.c => gator_buffer_write.c} | 24 +- drivers/gator/gator_cookies.c | 8 +- drivers/gator/gator_events_armv6.c | 2 +- drivers/gator/gator_events_armv7.c | 18 +- drivers/gator/gator_events_block.c | 2 +- drivers/gator/gator_events_ccn-504.c | 2 +- drivers/gator/gator_events_irq.c | 2 +- drivers/gator/gator_events_l2c-310.c | 2 +- drivers/gator/gator_events_mali_4xx.c | 2 +- drivers/gator/gator_events_mali_4xx.h | 2 +- drivers/gator/gator_events_mali_common.c | 2 +- drivers/gator/gator_events_mali_common.h | 2 +- drivers/gator/gator_events_mali_t6xx.c | 8 +- drivers/gator/gator_events_mali_t6xx_hw.c | 10 +- drivers/gator/gator_events_mali_t6xx_hw_test.c | 2 +- drivers/gator/gator_events_meminfo.c | 28 +- drivers/gator/gator_events_mmapped.c | 2 +- drivers/gator/gator_events_net.c | 2 +- drivers/gator/gator_events_perf_pmu.c | 2 +- drivers/gator/gator_events_sched.c | 2 +- drivers/gator/gator_events_scorpion.c | 2 +- drivers/gator/gator_fs.c | 47 +- drivers/gator/gator_hrtimer_gator.c | 8 +- drivers/gator/gator_hrtimer_perf.c | 113 --- drivers/gator/gator_iks.c | 2 +- drivers/gator/gator_main.c | 290 ++----- drivers/gator/gator_marshaling.c | 97 +-- drivers/gator/gator_trace_gpu.c | 13 +- drivers/gator/gator_trace_gpu.h | 2 +- drivers/gator/gator_trace_power.c | 6 +- drivers/gator/gator_trace_sched.c | 20 +- .../gator/mali/mali_mjollnir_profiling_gator_api.h | 2 +- .../gator/mali/mali_utgard_profiling_gator_api.h | 2 +- drivers/gator/mali_t6xx.mk | 9 + tools/gator/daemon/Android.mk | 15 +- tools/gator/daemon/Buffer.cpp | 259 +++++-- tools/gator/daemon/Buffer.h | 99 ++- tools/gator/daemon/CapturedXML.cpp | 11 +- tools/gator/daemon/CapturedXML.h | 2 +- tools/gator/daemon/Child.cpp | 174 ++--- tools/gator/daemon/Child.h | 4 +- tools/gator/daemon/Collector.h | 38 -

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

by Victor Kamensky

Hi Dave, Oleg, and All, Short story =========== It seems to me that ARMv7 uprobes need proper icache flush after xol write. Please look at [1] discussion for similar issue on ppc. It seems that flush_dcache_page was sufficient for latter architectures of PPC but it does not look that it is good enough for ARMv7. AFAIK know ARM V7 does not have "snooping Harvard caches" and needs something like __cpuc_coherent_user_range function call to sync up icache and dcache after instruction write through dcache. Patch that I propose follows this cover letter. There I introduced weak arch_uprobe_xol_sync_dcache_icache function that does traditional flush_dcache_page call and I redefined this function to __cpuc_coherent_user_range call in ARM v7 > case. [1] http://linux-kernel.2935.n7.nabble.com/Re-PATCH-6-9-uprobes-flush-cache-aft… Longer story ============ I was trying Dave's armv7 uprobes with SystemTap on Arndale board. I used Linaro linux branch 3.14 based that contained Dave's armv7 uprobes topic code. I believe it should be pretty much the same as armv7 uprobes code that went to Russell's tree. I was able to do one function simple test - it worked fine for me. But when I've tried to run many function like "probe process("foobar").function("*")" probe SystemTap my target process always crashed. After quite a bit of chasing the issue, I was able to come up with test case that shows several probes installed against 'ls' process. First probe placed at 'push {r4, r5, r6, r7, r8, r9, r10, r11, lr}' instruction, which is first in _getopt_initialize function, then script adds few more probes at _getopt_initialize addresses that are executed latter. And in those probes I dump registers set and top of stack. By looking at execution of script one may easily conclude that it looks like that for each probe 'push {r4, r5, r6, r7, r8, r9, r10, r11, lr}' instruction is always executed - one may see 36 bytes increase of stack size and see copy of corresponding registers on the stack. The code path is the following: handle_swbp -> pre_ssout pre_ssout -> xol_get_insn_slot xol_get_insn_slot -> copy_to_page xol_get_insn_slot -> flush_dcache_page pre_ssout -> arch_uprobe_pre_xol pre_ssout function calls xol_get_insn_slot which finds available slot in XOL area, that is mapped into user process and copies required instruction into xol slot. After that it calls flush_dcache_page, but icache is not flushed in ARM case by this function. So I think the following thing happens: first time first xol slot got 'push {r4, r5, r6, r7, r8, r9, r10, r11, lr}' instruction and it retrieved into icache. Latter when other probes are executed the same first slot of xol area it will get different instruction but because icache is not flushed CPU keep executing 'push' instruction. When I add the following testing patch that flush icache in arch_uprobe_pre_xol [kamensky@kamensky-w530 git]$ git diff diff --git a/arch/arm/kernel/uprobes.c b/arch/arm/kernel/uprobes.c index f9bacee..ef34623 100644 --- a/arch/arm/kernel/uprobes.c +++ b/arch/arm/kernel/uprobes.c @@ -117,6 +117,8 @@ int arch_uprobe_pre_xol(struct arch_uprobe *auprobe, struct pt_regs *regs) { struct uprobe_task *utask = current->utask; + __flush_icache_all(); + if (auprobe->prehandler) auprobe->prehandler(auprobe, &utask->autask, regs); it fixes my test problem, 'ls' executes fine, I am able to trace it with "process("foobar").function("*")" traces. Having complete icache flush is far from optimal. I was looking for better and more optimal and targeted icache flush. In discussion [1] and corresponding commit it was alluded that flush_icache_user_range should help but I don't think it will work for ARMv7. It seems that for ARMv7 flush_icache_user_range is not quite correct - it calls again 'flush_dcache_page(page)' which I don't think touches icache (other strange thing that it ignores len completely). I looked at armv7 kprobes code, in similar area arch_prepare_kprobe function calls arch_prepare_kprobe which calls flush_insn macro which is defined as call flush_icache_range, which in turn defines as __cpuc_coherent_kern_range(s,e). I looked at ptrace breakpoint write code as well that deals with similar issue. As far as I see it seems that the best function to sync up icache and dcache of user land process is to use __cpuc_coherent_user_range function which sync up dcache and icache memory region of given size and at given address on current core. In case of Arndale it goes through v7_coherent_user_range function. Given uprobes single step like use case it seem syncing up cache on current core is sufficient. If someone can confirm that __cpuc_coherent_user_range is right choice for this situation it would be nice. Test shows it work, we would need to know for sure. Next issue is how to integrate this call with cpu independent uprobes code. I introduced week arch_uprobe_xol_sync_dcache_icache function that calls flush_dcache_page as before, and for ARMv7 defined one that calls __cpuc_coherent_user_range. As far I understand flush_dcache_page was introduced for some relatively recent ppc CPU, it seems to be noop on x86. I was thinking that default weak version of arch_uprobe_xol_sync_dcache_icache should be empty and ppc define one that calls flush_dcache_page. But I have no way to test ppc case so I decided do conservative implementation and keep default version calling flush_dcache_page as it was before. Thanks, Victor Appendix: Test case that shows push instruction executed several times ====================================================================== SystemTap test script --------------------- root@genericarmv7a:~/systemtap/test# cat ls_t4_not_r4.stp function print_memory(addr:long, size:long) { i = 0; addr2 = addr; while (i < size) { printf("0x%8.8x: ", addr2); while (i < size) { printf ("0x%8.8x ", user_uint32(addr2)); addr2 = addr2 + 4; i = i + 4; if (i%16 == 0) { break; } } printf("\n"); } } probe process("/bin/ls.coreutils").function("_getopt_initialize") { sp = register("sp"); print_memory(sp, 64); print_regs(); printf("-> _getopt_initialize\n"); } probe process("/bin/ls.coreutils").statement(0x0001b2e8) { sp = register("sp"); print_memory(sp, 64); print_regs(); printf("-> 0x0001b2e8\n"); } probe process("/bin/ls.coreutils").statement(0x0001b2d8) { sp = register("sp"); print_memory(sp, 64); print_regs(); printf("-> 0x0001b2d8\n"); } probe process("/bin/ls.coreutils").statement(0x0001b408) { sp = register("sp"); print_memory(sp, 64); print_regs(); printf("-> 0x0001b408\n"); } probe process("/bin/ls.coreutils").function("_getopt_internal_r") { // sp = register("sp"); // print_memory(sp, 64); print_regs(); printf("-> _getopt_internal_r\n"); } execution of script ------------------- Look at log of script execution. Check how $sp changes at each probe (+36). And see that r4, r5, r6, r7, r8, r9, r10, r11, lr registers are always at top of stack. root@genericarmv7a:~/systemtap/test# stap -U -v ls_t4_not_r4.stp Pass 1: parsed user script and 100 library script(s) using 20520virt/16336res/1728shr/15260data kb, in 410usr/30sys/437real ms.
