Hello, # [GNU-767] Support changing SVE vector length in remote debugging * Analysed and fixed a couple more regressions in my branch. The change to per-thread target descriptions in gdbserver (which was the more challenging part) is now free of regressions. Now cleaning up the part that actually deals with the SVE vector length change. # Linaro CI's GDB testsuite results * Increased ccache's max size on most build bots. Sent email to the linaro-toolchain list summarising the current status of their ccache setup. * Started looking more closely into how ccache configuration is put together in our container scripts to document it on the wiki (together with the steps I took to change the ccache max size). -- Thiago

linaro-clang-armv8-lld-2stage has been red for a month

by Galina Kistanova

Hello Linaro Toolchain Working Group, linaro-clang-armv8-lld-2stage <https://lab.llvm.org/buildbot/#/workers/140> has been red since June 7th. Is anybody looking at the issue? Thanks Galina

[weekly][linaro] report week ending 7 Jul

by Peter Maydell

Progress: (short week, 3 days) * UM-2 [QEMU upstream maintainership] - More code review, as softfreeze is now quite close. I think we've finally got there with the SME patchset (the remaining problems with v5 were very minor) * QEMU-422 [QEMU Arm Neoverse V1 vCPU for TCG] - QEMU-315 OS Lock/DoubleLock work now upstream -- PMM

clang-armv7-vfpv3-full-2stage has been failing for more than 7 days and sends emails for each failed build

by Florian Hahn

Hi, It looks like https://lab.llvm.org/buildbot/#/builders/190 has been failing for the last week. It also sends out emails for each failed build, instead of for new failures only. The failure is below. It would be great if you could take a look and possibly adjust the configuration of the bot: [10/2380] Linking CXX shared library lib/clang/15.0.0/lib/linux/libclang_rt.scudo_standalone-armhf.so

[ACTIVITY] Report for week #26

by Thiago Jung Bauermann

Hello, # Linaro CI's GDB testsuite results * Implemented new version of change in the Abe shell script to correctly set auto-load-safe-path so that GDB can load libthread_db.so.1. Since GDB's configure script needs to be passed an argument containing literal dollar signs, use '@@' instead of '$' to avoid the shell misinterpreting it and substitute at the point of use. This version worked and was merged to the Abe repo. * Implemented and merged change in the Abe shell script to set variables pointing to language-specific target tools only if they are present in the path. This fixes Ada test failures in the GDB testsuite. * Implemented and merged improvement to our tcwg_gnu-build.sh script to allow specifying on the command line the Abe repo and branch to use. # [GNU-767] Support changing SVE vector length in remote debugging * Analysed and fixed a couple more regressions in my branch. -- Thiago

[ACTIVITY] report week ending 1 Jul

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - Code review (misc, plus another round on the SME patchset) - KVM Forum programme committee work * QEMU-422 [QEMU Arm Neoverse V1 vCPU for TCG] - Wrote and sent patches that deal with the last of the "small and uninteresting" dependencies of the V1 support epic (this one covers Feat_DoubleLock, which lets guest OSes suppress debug events as part of their power-down-a-CPU sequence) -- PMM

qemu meeting status

by Richard Henderson

Hi guys. I just realized that today's meeting will be right in the middle of dinner plans. I'll organize better next week. Anyway, here's my status: - Fourth SME patch set -- parts merged, and some bugs fixed. - Base/arm-compat portion of semihosting rewrite now upstream. Target-specific bits for m68k, mips, nios2, xtensa outstanding. - Almost done with FEAT_HAFDBS (hardware access/dirty updates). Big changes to ptw.c to make that work: 50+ patches. The reorg should make FEAT_RME easier though. r~

[ACTIVITY] Report for weeks #24 and #25

by Thiago Jung Bauermann

Hello, I just noticed that I didn't send a report for week #24. Sorry about that. For that reason, this report covers two weeks. # Linaro CI's GDB testsuite results * Submitted upstream patch fixing gdb_compile regexp to account for our GNATMAKE_FOR_TARGET value containing spaces. This should solve the Ada test failures in our CI. * Fixed the Abe shell script to correctly set auto-load-safe-path so that GDB can load libthread_db.so.1. Unfortunately the CI detected a problem with using the generated manifest to reproduce the toolchain build, so I'm back to the drawing board on this one. * Sent a Gerrit change request for the Abe script updating it to use release 12's branch and tag for GDB and gdbserver, and another one removing a workaround for a build problem fixed in GDB 9. * Sent a Gerrit change request for tcwg-dev-build.sh fixing a couple of issues I found when using it to build and test GDB. # [GNU-767] Support changing SVE vector length in remote debugging * Analysed and fixed a couple more regressions in my branch. # Misc * Attended a few online sessions from Linaro San Francisco Get Together. * Sent Gerrit change request updating the TCWG script that generates our SSH known_hosts file to include the Ed25519 host keys, which are now preferred in Ubuntu 22.04. * Was out one day due to “Corpus Christi” public holiday. -- Thiago

[weekly][linaro] report week ending 24 Jun

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - First week back after holiday: lots of catchup - Good progress with the code review queue, including getting rid of a few things that had been lurking in it for too long, and another pass through the latest SME series - KVM Forum programme committee work -- PMM

[ACTIVITY] Report for week #23

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging * Debugged and fixed a few issues in my code where gdbserver was having trouble with setting the target description for new threads. Also fixed regressions in a couple more testcases. # Linaro CI's GDB testsuite results * Luis commented on IRC that the GDB testsuite results from the Linaro CI seemed a bit high with about 540 failures, so I set out to investigate. The two biggest sources of failures are: 1. Ada tests were failing because they can't build their test executables. This is expected because we don't have the Ada compiler in the CI, but normally these testcases would just bail out as unsupported. Found out that there was a regex in the GDB testsuite that was (IMHO) too strict for our particular setup and fixed it. 2. All CTF tests are failing. The compiler in the CI seems to be building test executables with CTF debug info, so we do seem to have a problem there. The CI's GDB is also not loading libthread_db.so because of a GDB security setting, so I fixed that as well and expect some more tests to pass now. I still haven't submitted my fixes for 1. to upstream and for the libthread_db.so.1 issue to our CI scripts because I'm still working with jenkins-scripts and Abe to reproduce the CI environment to verify the fixes. -- Thiago
