Progress: * UM-2 [QEMU upstream maintainership] - sent patches that re-sync our defined set of usermode hwcap bits and ID register bitmasks with what the Linux kernel currently has - code review * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - FEAT_HBC: wrote and sent patch for this very simple feature - FEAT_MOPS: rolled v2 patchset based on review feedback * QEMU-486 [Update QEMU device models for FEAT_RME] - Looked at the SMMU spec to see (a) what realm-management related changes it needs and (b) where we are on the implementation of other features. Closed a few stale JIRA issues for features we've already implemented. - sent a patchset that advertises that we support SMMUv3.1-XNX (this is a no-op for our implementation) - investigated what the "expected" setup is for enforcing GPT checks on the GIC/ITS. Current front-runner is "the SMMU that's already in the system provides 'GPC checks only' for the accesses from these devices, as well as stage1/stage2 + GPT checks for PCI etc devices" (the term in the SMMU spec rev F.a is for a GPC-checks-only client device is "NoStreamID device") -- PMM

It looks like other NSS tests also fail in the same way. Is this a known issue on arm? Thanks, Sid

Fwd: [Linaro-TCWG-CI] gcc patch #75644: FAIL: 2 regressions

by Jonathan Wakely

I think this is because the patch changes libstdc++-v3/include/bits/version.def which requires version.h to be regenerated, by running 'make update-version' in the objdir/$target/libstdc++-v3/include directory. The patch I sent to gcc-patches (which is archived in patchwork) doesn't have the updates to the generated files, but what I committed to git does have them. ---------- Forwarded message --------- From: <ci_notify(a)linaro.org> Date: Mon, 11 Sept 2023 at 21:00 Subject: [Linaro-TCWG-CI] gcc patch #75644: FAIL: 2 regressions To: <jwakely(a)redhat.com> Dear contributor, our automatic CI has detected problems related to your patch(es).

[ACTIVITY] Report for week #36

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging - Continuing work on new approach to support changing SVE vector length in remote debugging. Fixed making native GDB work with the new approach using the DWARF location expression. Now porting the same approach to gdbserver, with an ad-hoc minimal location expression. # TCWG CI - Fixed GDB testsuite default timeout value, to make GDB check jobs for 32-bit ARM run in a less unreasonable time again. # Misc - Started preparation for future work on Guarded Control Stack for GDB. -- Thiago

[ACTIVITY] Report for week #35

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging - Resumed working on new approach to support changing SVE vector length in remote debugging. I was able to use DWARF location expressions in the target description to express the SVE vector register sizes in terms of the VG register. Also adapted the regcache to support variable-length registers, and removed the VQ value from the target description and from aarch64_gdbarch_tdep, making GDB use one target description regardless of the vector length size. Still ironing out some bugs, and haven't tackled gdbserver yet. -- Thiago

Re: [EXT] [Linaro-TCWG-CI] 2 patches in gcc: FAIL: 1 regressions

by Andrew Pinski

Just FYI. This test is just bogus and fixing it might be simple as using -fsanitize=undefined to check at runtime there is no undefined behavior being hit. In this case even if we do the comparison in `signed` and do the negate in `unsigned` types. we can still remove the negate in this case since we know the only value that will be still negative in that branch is LONG_MIN. So my patch just simplifies the inner comparison to that instead of `a < 0` and then be able to remove the neg. Someone else will have to fix the testcase since it is a testcase issue ... ________________________________________ From: ci_notify(a)linaro.org <ci_notify(a)linaro.org> Sent: Friday, September 1, 2023 3:07 PM To: Andrew Pinski Subject: [EXT] [Linaro-TCWG-CI] 2 patches in gcc: FAIL: 1 regressions External Email ---------------------------------------------------------------------- Dear contributor, our automatic CI has detected problems related to your patch(es).

Hi Jan, Your patch caused a regression [1] on aarch64-linux-gnu. Would you please investigate? I am having some trouble to reproduce it outside our CI environment, but it has been hitting this issues consistently and it does seems related to your patch. Let me know if you need any assistance in reproducing these. Thanks! [1] https://ci.linaro.org/job/tcwg_bootstrap_build--master-aarch64-bootstrap_pr…

Hi Richard, Your patch caused a regression [1] on aarch64-linux-gnu. Would you please investigate? I did a quick analysis and it seems that for test_copy_lane_f32, test_copy_lane_s32, test_copy_lane_u32, gcc is now generating zip1 instead of a ins; which does not seem fully correct.

[ACTIVITY] Report for week #33

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging - Continued working on new approach to support changing SVE vector length in remote debugging. # TCWG CI - Analysed GCC regression GNU-880 which is actually an XFAIL → XPASS so I sent a patch removing the xfail annotation. - Analysed GCC regression GNU-881. The problem is that we don't have Python in the ABE sysroot so a new Python GCC plugin testcase fails to build. Sent a patch to detect that situation and mark the test as unsupported. It was committed upstream. - Tested a couple of new versions of a GDB mailing list patch to see if it fixed the failure reported by the precommit CI. Reported results to patch author. - Fixed silly mistake spotted by Laurent in ABE Gerrit requests to use TIMEOUTFACTOR for DejaGnu testsuites. Adjusted it to not use the factor in GDB on armhf and sent new version for review. - Reviewed a couple of Gerrit requests. -- Thiago

[ACTIVITY] report week ending 18 Aug

by Peter Maydell

Progress (short week, 3 days): * UM-2 [QEMU upstream maintainership] - sent out another couple of "avoid VLA" patches * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - managed to write some first-pass code for the MTE checks for FEAT_MOPS memset operations. Got something together enough to send to RTH for some pre-review before I roll the approach out to the other insns. -- PMM

LLVM bots down for extended period

by Aaron Ballman

Hello! You are the point of contact for some build bots in the LLVM build lab that have been down for an extended period of time. If you're not the correct point of contact, can you please CC the right individual (if you know who they are)? The following bot(s) appear to have been down for multiple weeks: https://lab.llvm.org/buildbot/#/builders/clang-armv7-global-isel https://lab.llvm.org/buildbot/#/builders/clang-native-arm-lnt-perf https://lab.llvm.org/buildbot/#/builders/clang-aarch64-sve-vla-2stage https://lab.llvm.org/buildbot/#/builders/clang-aarch64-sve-vls-2stage https://lab.llvm.org/buildbot/#/builders/clang-aarch64-sve-vls https://lab.llvm.org/buildbot/#/builders/clang-armv7-vfpv3-full-2stage https://lab.llvm.org/buildbot/#/builders/clang-thumbv7-full-2stage Do you have plans to bring the bot back online? If not, that's okay -- just let me know and I can remove the bots from the lab for you. Thank you! ~Aaron

CMake requirements LLVM buildbots

by Mark de Wever

Hi, As discussed in [1] I just committed [2] to update the minimum CMake version in LLVM to 3.20.0. Unfortunately it seems the ARM builders in the libc++ precommit CI are running CMake 3.16.3 [3]. Would it be possible to update these builders? [1] https://discourse.llvm.org/t/rfc-upgrading-llvms-minimum-required-cmake-ver… [2] https://reviews.llvm.org/D144509a [3] https://buildkite.com/llvm-project/libcxx-ci/builds/19366#0186756a-1599-46e… Thanks, Mark

[ACTIVITY] Report for week #32

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging - Returned to implementing support for changing SVE vector length in remote debugging. The patch series I sent earlier this year used an approach that some maintainers weren't enthusiastic about (modifying the Remote Serial Protocol to request XML target descriptions). Now trying the approach they suggested, which is to extend target descriptions to support expressing vector registers whose length is given by the contents of another register. # TCWG CI - Following Maxim's suggestion, sent and merged Gerrit review requests to increase chance of tcwg_gdb_check jobs to be faster at detecting new or newly expired flaky tests: - 45151: tcwg_gdb: Increase job frequency - 45152: round-robin.sh (build_abe): Increase time to re-detect GDB flaky tests - Implemented change in ABE to support glibc's TIMEOUTFACTOR environment variable for DejaGnu testsuites. Testing on armv8l and aarch64. -- Thiago
