[ACTIVITY] Report for week #43

by Philippe Mathieu-Daudé

Progress: * QEMU-610 [Remove qemu_get_cpu() from hardware models] - Big rework of Cortex-A MPCore models. A common class is now used and various duplicated code from ARM boards got removed. Possible follow-up with QEMU-601 [Implement TYPE_CORTEXR52_PRIV].

[ACTIVITY] Report for week #43

by Thiago Jung Bauermann

Hello, # [GNU-981] FEAT_GCS (Guarded Control Stack) support in GDB - Started working on this feature. Currently adding ptrace and core file support for the NT_ARM_GCS regset. # Upstream community - Implemented fix for ‘--with-auto-load-dir’ and ‘--with-auto-load-safe-path’ configure options on Windows (since Eli mentioned it earlier this month) and posted “[PATCH] gdb/configure.ac: Fix auto-load options to work with Windows path separator”. -- Thiago

[weekly][linaro] report week ending 27 Oct

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - Took a prototype set of patches to add a second UART to the virt board which I'd written before going off on holiday; cleaned them up and got them into shape to send out for review. This is likely to be QEMU 9.0 material because we want to wait for the fix to EDK2 to make it handle the second uart more sensibly to get into an upstream EDK2 before landing the QEMU patches. - More code review work; sent this week's target-arm pull request * QEMU-292 [ARMv8.3 FEAT_NV, Nested Virtualization] - Started on implementation. This seems to be shaping up to be a less difficult task than our initial estimate suggested; I have code-complete patches for most of the necessary behaviour changes already. (Testing may be a more drawn-out effort :-)) -- PMM

Re: [PATCH v2] ARM: Block predication on atomics [PR111235]

by Ramana Radhakrishnan

+ linaro-toolchain as I don't understand the CI issues on patchwork.

With this it runs a few more tests. Yeah that's a wart that I don't like. armhf just implies the hard float ABI and came into being to help distinguish from the Base PCS for some of the distros at the time (2010s). However we didn't want to set a baseline arch at that time given the imminent arrival of v8-a and thus the specification of --with-arch , --with-fpu and --with-float became second nature to many of us working on it at that time. I can see how it can be confusing. With the advent of fpu=auto , I thought this could be made better but that is a matter for another patch and another discussion. However until then do remember to baseline to --with-arch , --with-fpu and --with-float . Unfortunate but needed. If there is a bug with --with-fpu=auto , good to articulate it as I understand that to be the state of the art.

Please try out various combinations of -march v7ve, v7-a , v8-a with the tool as each of them have slightly different rules. For instance v7ve allows LDREXD and STREXD to be single copy atomic for 64 bit loads whereas v7-a did not . > > > -(define_insn "atomic_load<mode>" > > - [(set (match_operand:QHSI 0 "register_operand" "=r,r,l") > > +(define_insn "arm_atomic_load<mode>" > > + [(set (match_operand:QHSI 0 "register_operand" "=r,l") > > (unspec_volatile:QHSI > > - [(match_operand:QHSI 1 "arm_sync_memory_operand" "Q,Q,Q") > > - (match_operand:SI 2 "const_int_operand" "n,Pf,n")] ;; model > > + [(match_operand:QHSI 1 "memory_operand" "m,m")] > > > > Remind me again why is it safe to go from the Q constraint to the m > > constraint here and everywhere else you've done this ? > > That's because the relaxed loads/stores use LDR/STR wrapped in an > UNSPEC.

While it is not policy yet to look at these bots but given the enthusiasm at Cauldron for patchwork and pre-commit CI and because all my armhf boxes are boxed up, I decided to do something a bit novel ! I tried reviewing this via patchwork https://patchwork.sourceware.org/project/gcc/patch/PAWPR08MB8982A6AA40749B7… and notice that https://ci.linaro.org/job/tcwg_gcc_build--master-arm-precommit/2393/artifac… says nothing could be built. Possibly worth double checking the status for it being a false negative as to why the build failed. It was green on patchwork but remembering that Green is not Green for CI in patchwork I clicked on the afore mentioned ci.linaro.org link and see that it's actually broken. regards Ramana

[ACTIVITY] Report for week #41

by Thiago Jung Bauermann

Hello, # TCWG CI - Flakiness in gdb.base/gdb-sigterm.exp causes false positives on tcwg_check_gdb--master-arm-precommit, so started investigating its failures. - Investigated regressions reported by the CI: - GCC regression GNU-935: Not a real regression, just already existing failures being reported for a new version of the C++ standard. - linux-next regression GNU-936: Fixed in the newest linux-next tree. - GCC regression GNU-962: Opened GCC bug 111802 ("New analyser diagram failures since commit b365e9d57ad4"). - GCC regression GNU-965: Arm already opened GCC bug 111784 ("[14 Regression] aarch64: ldp_stp_{15,16,17,18}.c test failures since r14-4579.") about this issue. - GCC regression GNU-966: This problem has been fixed in trunk. - linux-next regression GNU-967: A patch was sent to fix the error. # [GNU-767] Support changing SVE vector length in remote debugging - Working on adapting gdbserver's regcache to support registers with a variable size. - Also enabling the target description XML to express vector register sizes in terms of another register. -- Thiago

Fwd: [Linaro-TCWG-CI] llvmorg-18-init-7933-ge13bed4c5f35: slowed down by 6% - 464.h264ref on aarch64 O2

by Maxim Kuvyrkov

Hi Dmitriy, Linaro Benchmarking CI has flagged several interesting code-speed and code-size regressions for your patch -- see [1]. In particular, could you check if below regressions can be avoided: - grew in size by 21% - 473.astar:[.] _ZN7way2obj12releasepointEii - slowed down by 61% - 505.mcf_r:[.] price_out_impl Both of these are for 32-bit ARM, but AArch64 also has code-speed and code-size regressions. Let me know if you need any assistance in reproducing these problems.

[ACTIVITY] Report for weeks #37 to #40

by Thiago Jung Bauermann

Hello, Attended two events in a row in September, so had a bit of a time crunch and the weekly report fell through the cracks... # TCWG CI - Investigated and fixed a few false positives in the GDB precommit CI which were caused by random failures in gdb.threads/process-dies-while-detaching.exp. Posted upstream and later committed patch fixing the testcase to be more stable. - After conversations during GNU Tools Cauldron and following Maxim's suggestion, changed Linaro's CI to use the read1 library while running the GDB testsuite to improve the stability of its results. - After review from Tom Tromey, posted v2 and later committed a patch which adds '--with-additional-debug-dirs' configure option. - Committed a couple of changes to our CI scripts which make sure that the kernel.yama.ptrace_scope and kernel.core_pattern sysctls have correct values for running the GDB testsuite. # [GNU-767] Support changing SVE vector length in remote debugging - Now that Luis pushed his SME and SME2 patches, merged current GDB main branch into my local branch. It builds but doesn't work yet. # GDB Upstream - Reviewed patch series "[PATCH v3 0/4] Dynamic properties of pointers". - Investigated upstream bugzilla "18898 - Cannot specify non-default list of directories as argument of --with-auto-load-dir on Windows", but concluded it's an autoconf limitation that isn't easy to fix. # Misc - Prepared for Linaro's Employees Meeting. - Attended GNU Tools Cauldron. - Took a few days of vacation. -- Thiago
