perf issue: etm traces are dumped to the wrong AUX buffer

by Zied Guermazi

hi I am using perf syscall to collect etm traces for btraces implementation in GDB running on Linux kernel 5.9.1 on a cortex A7. in this test case, I am debugging a multi-threaded process (2 pthreads). For each thread, GDB is calling the sys call perf_event_open and gives the corresponding thread ptid.lwp as argument. for each syscall, the AUX buffer is mmap(ped) to a dedicated memory. this is working for almost all test cases I have, except this one, where it has 50% failure rate when executed manually. 90% failure rate when executed from a script. the source code for debugged program is listed below. /* This testcase is part of GDB, the GNU debugger.

[ACTIVITY] report week ending 11 Dec

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] + sent out a pullreq for 6.0, and did a bunch more patch review + sent out a respin of the "build one manual, not five" RFC I sent last month; nobody objected to the RFC so this time around it is a proper PATCH + had a brief scan through the GIC architecture specification to look at what extra GICv4 and GICv4.1 add (the big thing is that the ITS is now mandatory; QEMU doesn't emulate that yet) * VIRT-364 [QEMU support for ARMv8.1-M extensions] + SSE-300 timer device model more or less functionally-complete (though untested). I ran into some issues with QEMU's Clock APIs that I needed to fix in the process -- sent a patchseries trying to address those. + Got most of the outstanding v8.1M patches into master; sent a small patch series with respins of the last 4 or so patches that needed more work thanks -- PMM

== Progress == * GCC upstream validation: - reported several regressions/new failures * GCC - Neon intrinsics: vceqq, vceqz and vceqzq for p64 patch: no feedback - MVE autovectorization: committed vand and vorr patches. Sent updated versions of veor, vbic and vmvn. vshr and vshl need some refactorization with Neon versions, clarified the best way to go with Arm maintainers. - PR97875 (suboptimal vectorization on MVE): investigation shows that movmisalign patterns are missing for MVE. * benchmarking: - Scripts to run coremark on stm32 now merged, debugging issues. No progress this week. * infra: - debugging issues with our docker containers - looking at ABE patches * misc: - provided feedback to Arm's partner wrt Intrinsics documentation == Next == * GCC/cortex-M testing improvements & fixes * cortex-m benchmarking * MVE auto-vectorization/intrinsics improvements

Timeout tests timing out

by David Blaikie

The clang-cmake-armv8-lld (linaro-toolchain owners) buildbot is timing out trying to run some timeout tests (Dan Liew author): Pass: http://lab.llvm.org:8011/builders/clang-cmake-armv8-lld/builds/5672 Fail: http://lab.llvm.org:8011/builders/clang-cmake-armv8-lld/builds/5673 Is there anything we can do to the buildbot? Or the tests? (bump up the time limits or maybe remove the tests as unreliable?)
