[weekly][linaro] report week ending 22 Sep

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - Implemented Neoverse N2 CPU model (easy as it's very similar to the Cortex-A710 we just implemented; but because it supports 48 bit physical addresses we can use it in the sbsa-ref board, so it's worth having both) - Wrote code to wire up the NS EL2 virtual timer IRQ on the virt board. This is part of FEAT_VHE, and we implemented the timer itself in the CPU ages ago, but forgot to ever wire up the interrupt line on the board models. Unfortunately doing this runs into a bug in EDK2 where it incorrectly asserts when it sees a dtb that reports the interrupt line. Leif Lindholm wrote patches to fix this in EDK2, but we'll need to update the QEMU testsuite and figure out how to communicate the need for an updated EDK2 to users. - Looked again at a long-standing missing feature in the virt board where it only has one UART. The main blocker for adding a second one has been odd EDK2 behaviour when the dtb tells it there are two UARTs. Investigated and wrote up exactly what it does to start a discussion about improving it. - Put together a target-arm pull request - Squashed a few -Wshadow warnings - Looking at a bug involving QEMU's PSCI emulation when QEMU is faking being EL3 firmware for a Linux guest * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - Implemented and sent a patch for FEAT_HPMN0 (a very easy feature that makes MDCR_EL2.HPMN==0 valid) -- PMM

Re: [EXT] [Linaro-TCWG-CI] basepoints/gcc-14-4038-gb975c0dc3be: Failure

I could not reproduce the bootstrap failure at -O3 on x86_64. I used --with-build-config=bootstrap-O3 . Maybe this is an arm (32?) only issue.

[ACTIVITY] report week ending 15 Sep

by Peter Maydell

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).

[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

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

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?

[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

Progress: * UM-2 [QEMU upstream maintainership] - code review, notably: + RTH's setnegcond series + Jean-Philippe's fixes for various FEAT_RME bugs + Akihiko's series to make KVM '-machine none' not default to 40 bits of IPA space if the host doesn't supoprt that (like the Apple CPUs) - sent a patch to catch the illegal exception return case from EL3 with bad SCR_EL3.{NSE,NS} - respin and resend of ptw cleanup patchset - tidied another 'BiteSizedTask' entry into a gitlab issue - went back to an old minor cleanup task: getting rid of the last dozen or so uses of variable-length arrays in the codebase (so we can enforce not using them in the compiler, and avoid unchecked-on-stack-allocation security bugs). Sent patches to zap a few more. * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - thinking a bit more about FEAT_MOPS and MTE checks, but ultimately not much progress: didn't find enough hours with a sufficiently alert mind... -- PMM

Progress: * UM-2 [QEMU upstream maintainership] - release related stuff: handling merge requests, etc (now passed back to RTH again) - sent some patches for a few easy coverity issues - worked through some code review (in particular some patches from new contributors) - created a gitlab "bite sized task" issue that better explains and has more detail on the "convert from malloc to g_malloc" suggested task for new contributors * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - a little more progress with FEAT_MOPS. I now have an untested implementation of the memset insns which I think is complete except for MTE tag checking -- PMM

[ACTIVITY] report week ending Jul 21

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - fixed some places in our RTC device models where we were putting a time_t or time_t offset into a 32-bit variable - took over from RTH briefly for pullreq merge handling - sent some patches fixing minor Coverity issues - investigated a couple of "test case fails on big-endian host" errors: sent patches for Sparc FPRS handling and for the Arm SMMUv3 model - Investigated report that our MPS2/3 M-profile models don't have the same number of MPU regions configured as the real FPGA images, and so you can't run the same Zephyr binary on both. Have some preliminary patches to correct the number of regions. * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - finally got back to FEAT_MOPS work; wrote a skeleton of code for the memset operations that's about right up to the point where it needs to actually do the memset... -- PMM

Progress: * UM-2 [QEMU upstream maintainership] - investigated and fixed a bug in page-table-walk handling of debug accesses that was introduced by the FEAT_RME changes - that prompted me to look at a cleanup of some of the ptw code so that we consistently look at "which space is this walk for" and don't carry around a parallel boolean "secure/non-secure" that duplicates that information - found and fixed a few other ptw bugs along the way -- PMM

[ACTIVITY] Report for week #25

by Thiago Jung Bauermann

Hello, # TCWG CI — GDB - Investigated why the GDB check jobs stopped succeeding, as reported by Maxim. It turns there was an upstream commit (which was soon reverted) that broke generation of the gdb.sum file and consequently our baseline results became empty. Theoretically the CI should recover from that but we don't deal well with this corner case. With Maxim's help, restored the baseline and now things should be back to normal. Will improve our scripts to avoid this trap. # CI Babysitting This week was my turn to baby sit the CI. - Investigated 12 regressions in GCC and reported 3. The others were already fixed. - Investigated 1 regression in GDB but it wasn't actually one. - Investigated 1 regression in QEMU but it was already fixed. -- Thiago

[ACTIVITY] report week ending 23 Jun (inc. KVM Forum trip report)

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - catch up on email after a week away - Put together some arm pull requests - sent out draft QEMU summit minutes for review - sent patch to avoid using the buggy __builtin_subcll in Apple Clang 14 - sent patch fixing build error with newer xkeyboard-data - some gardening of Coverity issue reports Last week was KVM Forum in Brno -- here's a quick trip summary: This year KVM Forum was a slightly smaller conference (2 days, single-track), as we are now organizing it independently of the Linux Foundation. The independent organization went pretty well this year (despite the slightly awkward short notice) and the conference was very useful both for the talks and for the hallway track. Interesting talks (just a sampling biased to my interests): * KVM: Arm Confidential Compute Architecture Support Suzuki Poulose presented a summary of FEAT_RME and the CCA hardware and software architecture, and how it's intended to fit into KVM * KVM/arm64: Episode V - The Blob Strikes Back Immediately following was Marc Zyngier and Oliver Upton from Google: their talk was a pretty strong critique of the CCA software stack architecture. Their central point is that having the RMM be "part of the firmware" rather than "part of the hypervisor" is going to cause a rerun of all the issues we've seen with dubious and non-upgradable vendor code in EL3. Secondly, having the fixed API between the hypervisor and the RMM restricts to least-common-denominator and provides no room for experimentation and optimizations. They want an architected way to deploy an RMM at boot time. * Handling complex guest exits with eBPF Will Deacon presented what he described as "conference driven development" -- an interesting prototype of having device models in the host kernel that are implemented in eBPF. This (in theory) gives you the performance gains of an in-kernel device without it putting a lot of C code onto the security boundary between the guest and host. * Challenges Revisited in Supporting Virt CPU Hotplug on architectures that don't Support CPU Hotplug (like ARM64) James Morse (Arm) and Salil Mehta (Huawei) presented on CPU hotplug. The underlying problem here remains that Arm has no hardware hotplug handling, so there's no clear model for what hotplug on a VM should look like. Cloud vendors have an obvious desire for the x86-style tooling to Just Work on Arm too. The gap between "we have a prototype that seems to work" and "upstreamable maintainable code" has not yet been bridged, though... * QEMU Arm CPU models and KVM Cornelia Huck (RedHat) had a talk that was intended as a statement of the problem rather than a proposed solution. At the moment we only let a KVM guest see the same CPU type as the host and don't have a mechanism for presenting a subset of features to it. KVM is about to get support for letting the VMM define what the guest should see in the ID registers, but how should we expose that to QEMU users without ending up with a thousand command line sub-options to turn on and off every architectural FEAT_FOO? And how do we deal with errata workarounds, which the guest currently selects based on the MIDR value? As usual, we held the QEMU Summit (an hour-long maintainer discussion mostly about process and organizational issues) during KVM Forum. I still need to write up the minutes for this, but they'll be published on the qemu-devel list shortly. thanks -- PMM

Need emit_expr to write right shifted value.

by zac.walker＠linaro.org

Hi, In binutils I need to write an offset between two symbols shifted right by 2 bits. This offset is written to the xdata section. My code currently looks like this: exp.X_op = O_subtract; exp.X_add_symbol = symbol1; exp.X_op_symbol = symbol2; emit_expr (&exp, 2); This works fine but obviously the result value is not shifted. Anyone have a good option is to shift the output of emit_expr at write time? I cannot use resolve_expression because the symbols do not have correct addresses at the time this code executes. Any help appreciated, Zac

by Thiago Jung Bauermann

Hello, # TCWG CI — GDB - Changed tcwg_gnu-build.sh to apply GDB testsuite patch to avoid infinite loop in tcwg_gdb_check--master-arm jobs, while it isn't committed upstream. - Started investigating corrupt gdb.sum.1 file in tcwg_gdb_check--master-arm jobs. I can't reproduce it by manually running the CI's "make check-gdb" command line, nor by using ABE. I can reproduce it with tcwg_gnu-build.sh though. - Came up with validate_failures.py change to make it cope with the corrupt gdb.sum.1 file, while the underlying cause isn't known. Submitted the change upstream. # TCWG Infrastructure - Reviewed some Gerrit requests for our CI scripts. # Misc - Did some travel planning for Linaro Employee Meeting and GNU Tools Cauldron. -- Thiago

Hello, # TCWG CI — GDB - Addressed review comments and sent v2 and v3 of the patch fixing loop in gdb.reverse/step-reverse.exp. The testcase's original author gave his Reviewed-by, now waiting for approval by a maintainer. In the meantime, set up our CI to apply the patch locally. - Sent patch to the GDB mailing list implementing configure option '--with-additional-debug-dirs' to allow building a GDB binary with a custom install prefix but which also looks for debug info in /usr/lib/debug. This should solve the SIGILL issue on armhf-linux in our CI, and allow a few more tests to run on aarch64-linux. # TCWG Infrastructure - Reviewed some Gerrit requests related to notification and baseline updating. -- Thiago
