[VIRT-327 # Richard's upstream QEMU work ] Misc patch review. [GCC] I looked into Adhemerval's libgomp-scalability patch set. The code looks good, and I can't see anything wrong. The cancel-parallel-2 test that's reported to regress, does, sometimes. It never fails for me on qemu-test (aarch64, tx1). It *only* fails under the dejagnu test harness on x86_64 and ppc64le. When run by hand it succeeds, always. I cannot explain that at all. I've run the testsuite with OMP_DEBUG_ENV=verbose and see that the dejagnu environment is as expected. Anyway, I can't make forward progress because I can't reproduce the problem under controlled conditions. r~

Progress: * VIRT-65 [QEMU upstream maintainership] + More wrangling of release stuff and unreliable infrastructure. * VIRT-364 [QEMU support for ARMv8.1-M extensions] + Managed to find a few days to put in some more work pushing fp16 handling forwards. I now have implementations of fp16 for most of the VFP insns (still todo: VCVT, VSEL, VMAXNM/VMINNM, VRINT*; then the few insns that are new-for-fp16. Then all of Neon, which is larger.) thanks -- PMM

4 day week. [VIRT-327 # Richard's upstream QEMU work ] Bug hunting vs aa32 ldrex/strex. I had hoped it would be relatively easy to reproduce -- just run something from the .NET testsuite -- but even getting that far wasn't obvious. So I put that aside; let's see if Peter's request for an actual reproducer gets results. Bug hunting vs aa64 gcc sync-4.c as reported by clyon. I determined that it's not the fault of the null-pointer dereference, and that something goes wrong somewhere in libgcc's exception unwind prior to the c++ throw. But it doesn't fail all of the time. And worse, the problem vanishes when randomize_va_space is disabled. So I can neither get a "good" vs "bad" trace without needless differences nor produce a failure under gdb. I should try again with rr and see if that works... r~

Re: buildbot failure in LLVM on clang-cmake-armv7-full

by David Blaikie

Linaro folks - why is this buildbot sending mail when it's already red (looks like this buildbot has been red for a while, at least 11187 seems to be red for the same reason that 11188 is red - so the people on this blame list aren't relevant)? That adds noise to the buildbot results & makes it harder for developers to find actionable email.

Progress: * VIRT-65 [QEMU upstream maintainership] + respun the QEMU side of the "fix 32-bit-guest readdir of ext4 filesystems on a 64-bit host" work to match Linus Walleij's most recent kernel patch. + code review (actually emptied my queue for the first time in forever): - patchset adding some missing devices to MPS2 boards - another round of RTH's MTE patchset (now fully reviewed and ready to go in) - SMMUv3.2 range-invalidation support patchset from RedHat - RTH's implementation of the kernel MTE ABI for QEMU linux-user + had a look at some of the lurking Coverity issues * VIRT-364 [QEMU support for ARMv8.1-M extensions] + fp16 support: started by working out risu patterns for all the affected instructions so we have a means for testing the changes. + implemented a handful of fp16 insns; plan to back-burner this for a little while as it's not going to be complete before we freeze for QEMU 5.1, so work like reviewing the MTE patchset and other for-5.1 efforts will take priority.

[VIRT-339 # ARMv8.5-BTI, Branch Target Identification ] Updated to match the latest kernel for-next/bti-user branch; I hope this is going to be merged for 5.7. Posted v9 for review. [VIRT-349 # QEMU SVE2 Supprt ] More RISU work to improve support for SVE. Stephen Long has posted some sve2 risu patterns that need reviewing, and I plan to test all of that next week vs ArmIE. I had a start on rebasing my current sve2 patch set on master, with lots of prereqs merged. But stopped in the middle because I realized that I wanted to get all of the RISU work done first, so that I can test each patch as it is updated. r~ PS: Out all next week on holiday.

An issue of svld1_f64() and svld1_vnum_f64() in gcc10 with ‘-O0’

by Guodong Xu

Hi, Chris, and Linaro Toolchain team, Recently I found an issue of SVE intrinsics (svld1_f64, svld1_vnum_f64) when using gcc -O0 (gcc 10.0.1 debian nightly build, optimization level 0). Would you please help me to reach out to people who can fix it? svld1_f64() is a function defined in Arm intrinsics for SVE (scalable vector extensions) [2]. Changing -O0 to -O1 makes the issue disappear. svld1_vnum_f64() has the same problem. To show the issue, I wrote this simple test program, see test1.c in [1]. A full issue report and gcc version string can be found in the attached pdf file. [1] My test program: https://github.com/docularxu/sve-code-test/tree/working-svld1_f64 [2] Arm SVE intrinsics: https://developer.arm.com/docs/100987/latest Feel free to contact me if you need more details. Best regards, -Guodong Xu

[LLVM] Upcoming upgrade of CMake

by Louis Dionne

Hi, You are receiving this email because you are listed as the owner for at least one LLVM build slave on http://lab.llvm.org:8011/buildslaves <http://lab.llvm.org:8011/buildslaves>. This message is a heads up concerning the upcoming upgrade of CMake discussed here: http://lists.llvm.org/pipermail/llvm-dev/2020-March/140349.html <http://lists.llvm.org/pipermail/llvm-dev/2020-March/140349.html>. As discussed on that thread, LLVM will require CMake 3.13.4 in order to build after the release branch for LLVM 11.0.0 is created. Using an older CMake will be an error. In order to keep things running smoothly, we would greatly appreciate if you could upgrade CMake on your builder(s) to at least CMake 3.13.4 before the next release branch is created. Please reply privately to this email when you've done so -- this will allow keeping track of who has and has not upgraded. Thank you and have a wonderful day, Louis

Short week (4 days) == Progress == * GCC upstream validation: - reported a couple of failures/regressions - still looking at improving MVE tests to avoid failures in several non-supported configurations. No satisfactory solution so far (there are always combinations of GCC configure option and validation-time options that are incompatible and produce failures instead of unsupported) - maybe we should agree on a common way of running the testsuite * GCC: - PR94743 (IRQ handler and Neon registers): sent a patch to emit a warning. More ambitious patches would be too intrusive for stage 4. * FDPIC/GDB: - no progress this week * misc: - infra fixes / troubleshooting / reviews - started looking at cortex-m benchmarking harnesses == Next == * FDPIC GDB * GCC/cortex-M * cortex-m benchmarking

[ACTIVITY] report week ending 24 Apr

by Peter Maydell

Progress: * VIRT-65 [QEMU upstream maintainership] - We needed an rc4 (which I wasn't very surprised about), so more release wrangling again. - Noticed some bugs in how we set ID registers for the AArch64 'max' CPU; sent patches (one of which seemed worth getting into rc4) - There's been a long-standing problem where a linux-user QEMU running on a 64-bit host and emulating a 32-bit guest can't deal with the 64-bit hash 'offsets' from ext4 getdents, which causes guests using newer glibc to fail. Linus Walleij wrote a kernel patch which allows QEMU to request that the kernel gives it hash values that will fit into 32 bits. I wrote an RFC QEMU patch that would use this and tested that this does indeed solve the problem. Discussion is continuing on the kernel size about what the correct API for this is, but the principle that the kernel should change seems to be accepted. - A bug was raised that BKPT for arm linux-user wasn't causing SIGTRAP; sent patches fixing that and some other issues I noticed in that bit of the code while I was fixing it. - code review: + a patch adding proper FIFO emulation to the PL011 UART model + rth's patchset improving codegen of neon integer-compare-vs-0 insns + xilinx patchset to disable unsupported FDT firmware nodes + patchset adding kaslr-seed properties to the virt board dtb (mostly useful for OP-TEE) * VIRT-364 [QEMU support for ARMv8.1-M extensions] - Progress with neon decodetree conversion. I've now completed all the 3-reg-same insn grouping, which is a large enough amount that I'm planning to send out a patchset with what I have so far. Need to refactor/tidy up some bits of the code first, now I can see what the completed conversion looks like. thanks -- PMM

Re: buildbot failure in LLVM on clang-cmake-armv8-lld

Short weeks around Easter. [VIRT-349 # QEMU SVE2 Support ] Lots of progress on insn implementation. Several patches from Stephen Long merged. He's coming up to speed nicely. Some good review from Laurent Desnogues. Spent some time writing a version of strspn for Arm optimized-routines, as a way of testing the NMATCH instruction. Found bugs in the tcg optimizer instead. Still in the process of rebasing the branch upon those fixes, and upon patch review from Peter. [VIRT-327 # Richard's upstream QEMU work ] Couple of patches for 5.0.

How to use 'runtime-linaro-...' and 'sysroot-linaro-...' archives ?

by Константин Аладышев

Hello! I know, this is probably a very stupid question, but I couldn't find an answer for it. On the page https://releases.linaro.org/components/toolchain/binaries/latest-5/arm-linu… there are 3 major download components: gcc/sysroot/runtime. I download 'gcc', add 'gcc-linaro-.../bin' to my PATH and cross compile my apps. On my target system, I need 'libc', and it is present in the 'sysroot-linaro-...'. Do I need to copy all of the contents of 'sysroot-linaro-...' folder to my target? 'linaro-sysroot' folder is kinda big. 'libc.so' library is 13MB. If there is a way to decrease its size, if I want to use Linaro compiled programs on an embedded target? And what is a purpose of 'runtime-linaro-..." component?

Failing libcxx-libcxxabi-libunwind bots

by Louis Dionne

Hi, It looks like several bots assigned to you started failing after e6a39f00e8d0 was committed: http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-armv8-linux-no… http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-armv8-linux http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-aarch64-linux http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-aarch64-linux-… They all fail on the test libcxx/test/libcxx/modules/stds_include.sh.cpp with the following error: <...>/libcxx/test/libcxx/modules/stds_include.sh.cpp:28:2: fatal error: file '<...>/libcxx/include/type_traits' has been modified since the module file '<TMP>/ModuleCache/1E92AHT/std-1V9DLRO.pcm' was built #include <vector> ^ <...>/libcxx/test/libcxx/modules/stds_include.sh.cpp:28:2: note: please rebuild precompiled header '<TMP>/ModuleCache/1E92AHT/std-1V9DLRO.pcm' 1 error generated. Our other bots are not failing, so I very strongly suspect this is not because of the change itself, but rather some weirdness in your bot configuration. For that reason, I will *not* revert the change (that would likely not improve the situation anyway). Can you please collaborate with us to understand and fix the issue? Thanks, Louis

Libc++'s filesystem tests are known to fail when run as root, because some of them need to check for failure to access some files for which there's no permission. This doesn't seem to work when run as root. Can you work with us to resolve this issue? Thanks, Louis

[VIRT-349 # QEMU SVE2 Support ] Met with Qualcomm on Friday to discuss sharing the development work, and help start bringing their new-hire, Stephen Long, up to speed on qemu. Gave Stephen generic qemu development pointers, and a simple set of SVE2 instruction on which to wet his feet. [VIRT-327 # Richard's upstream QEMU work ] Better constant propagation and allocation for TCG. Worked on probe_guest_base as a follow-up to some of the work Alex was doing wrt init_guest_space. Misc patch review for 5.0. [GCC] Posted v3 of aarch64 cmpti patch set. r~

[ACTIVITY] report week ending 3 Apr

by Peter Maydell

Progress: * VIRT-65 [QEMU upstream maintainership] - More freeze related wrangling... * VIRT-241 [QEMU ISA Support for A-profile] - pushed the ARMv8.2-TTS2UXN patchset out to the mailing list - found and fixed a bug in our PAN support where we were making PSTATE.PAN forbid execute access, not just data access * VIRT-364 [QEMU support for ARMv8.1-M extensions] - Started on some preliminary refactoring that we'll need so we can more conveniently modify the decoder for v8.1M: converting the A32/T32 Neon decoder to use decodetree. I've done the "post-v8.0 extensions" instructions, and started on the loads-and-stores. thanks -- PMM

TX2 + C++17 problems

by Jussi Lind

Hi, We are having some serious problems after we upgraded from C++14 to C++17 on an Jetson TX2 ARM device. Our system tests started to behave differently and fail. It seems that when our application uses a library (also developed by us) some data gets corrupted when delivered to a class constructor. For example, the .second of and std::pair<float> appears to be the .first and the .second is garbage. This is deterministic, but different tests are failing depending on the combination: library C++17/C++14 <-> application C++14/C++17. This is on Ubuntu 18.04 and gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04). Nothing like this happens on Intel. So: ARM, C++14: OK Intel, C++14: OK ARM, C++17: FAIL Intel, C++17: OK Any ideas what could cause this? I know this is a bit vague, but this a commercial, closed-source application so I cannot yet give any other information. BR, Jussi Lind

[ACTIVITY] report week ending 27 Mar

by Peter Maydell

Progress: * VIRT-65 [QEMU upstream maintainership] - Softfreeze this week, so a lot of pull request handling, and one last small arm pullreq to put together and send out - Our Coverity Scan setup was broken (the person who usually does the builds updated his machine to a newer Fedora which broke the tool). I pulled up an old patchset I had from a year ago which scripts things so you can do a build-and-upload automatically via Docker so that we're not dependent on one person for this. This took longer than I expected as there were a bunch of things that needed fixing both in the scripting and in bits of the codebase that the tools warned about. Patch series sent. - When we did get a Coverity run through, it reported 112 new issues; spent some time going through and triaging them (lots of false positives but also lots of real bugs) and submitting patches for some of them. * VIRT-364 [QEMU support for ARMv8.1-M extensions] - sketched out the work required and created some 'story' level cards to go under the epic. Still open questions: + should we model Cortex-M55 or a more generic 'max' CPU? + what board model do we want to use? + does LITE have any guest code using v8.1M features for testing? Random notes: * my new desk chair and standing desk arrived this week (the latter still needs assembling...) so I am gradually improving the rough edges of my WFH setup. thanks -- PMM

[GCC] Two revisions improving TImode comparisons for aarch64 (PR94174). https://gcc.gnu.org/pipermail/gcc-patches/2020-March/542447.html [Kernel] Follow-up on a discussion a few weeks ago re __range_ok.
