== Progress == * GCC upstream validation: - restarted validation after e/o year maintenance - catching up, no regression to report so far * GCC - Neon intrinsics: vceqq, vceqz and vceqzq for p64 patch: no feedback - MVE autovectorization: movmisalign accepted, waiting for boostrap results vshl and vshr: pinged. - helping with cortex-m0 libgcc patch validation * benchmarking: - Scripts to run coremark on stm32 now merged, debugging issues. No progress this week. * infra: - reviewed ABE patches == Next == * GCC/cortex-M testing improvements & fixes * cortex-m benchmarking * MVE auto-vectorization/intrinsics improvements

[ACTIVITY] report week ending 8 Jan

by Peter Maydell

Progress (2 day week this week): * UM-2 [QEMU upstream maintainership] + Unsurprisingly, pretty much just catching up with email, pull requests, code review, bug reports, respins of patchsets... * QEMU-364 [QEMU support for ARMv8.1-M extensions] + The final parts of base v8.1M and Cortex-M55 support are now in master. thanks -- PMM

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
