Progress: * UM-2 [QEMU upstream maintainership] - Joint Linaro/Arm meeting on the Realm Management Extension (RME). Mostly this was "how the software stack is going to work"; some useful discussion on how this intersects with QEMU, both as a potential emulation platform for software development and also as the VMM for a realm-using KVM virtual machine. - Kicked off a discussion thread on getting rid of the last parts of our "ad-hoc CI" this release cycle. The main thing that's not yet handled by Gitlab CI is FreeBSD and NetBSD hosts. We might be able to do this if we can find an x86 Linux machine to act as a gitlab runner (it needs to be able to run guest BSD VMs). * QEMU-422 [QEMU Arm Neoverse V1 vCPU for TCG] - Several small features have now made it upstream so those subtasks have been closed out - Looking at FEAT_RASv1p1 and FEAT_DoubleFault. The first of these is easy because we only model the minimal "no error records" RAS: I think we can simply bump the ID register fields to indicate support. The second is a little bit more interesting because the new SCR_EL3.EASE bit means we suddenly have a source of physical SErrors (from synchronous external aborts) when we previously could not have any... -- PMM

[ACTIVITY] Report for week #19

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging * Continued working on the testsuite regressions introduced by my code. - Found out that the crash I was investigating (which happens when gdbserver thinks that the kernel doesn't support SVE and crashes) only occurs with kernel v5.4 from Ubuntu 20.04 and not with Ubuntu 22.04's v5.15. In the former version, ptrace(PTRACE_GETREGSET, …, NT_ARM_SVE, …) often returns -1 (but not always) and gdbserver interprets this as meaning that SVE isn't supported. The newer kernel always returns successfully from this call. gdbserver still acts weird so there's more digging to do, but at least it doesn't crash. # Misc - Took one day of vacation. -- Thiago

It also makes the case we insert into the IL somewhat distinct from inserting into a standalone sequence in that it simplifies built expressions the same way as inserting and calling fold_stmt (..., follow_all_ssa_edges) would. When inserting into a standalone sequence we restrict simplification to defs within the currently building sequence. The patch only amends the tree_code gimple_build API, I will followup with converting the rest as well. The patch got larger than intended because the template forwarders now use gsi_last which introduces a dependency on gimple-iterator.h requiring mass #include re-org across the tree. There are two frontend specific files including gimple-fold.h just for some padding clearing stuff - I've removed the include and instead moved the declarations to fold-const.h (but not the implementations). Otherwise I'd have to include half of the middle-end headers in those files which I didn't much like. 2022-05-12 Richard Biener <rguenther(a)suse.de> gcc/cp/ * constexpr.cc: Remove gimple-fold.h include. gcc/c-family/ * c-omp.cc: Remove gimple-fold.h include. gcc/analyzer/ * supergraph.cc: Re-order gimple-fold.h include. gcc/ * gimple-fold.cc (gimple_build): Adjust for new main API. * gimple-fold.h (gimple_build): New main APIs with iterator, insert direction and iterator update.

[ACTIVITY] report week ending 13 May

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] + had a look at adding an option to allow semihosting from userspace (handy for some test case purposes); have a working prototype which I used to test the FEAT_IDST patch, but probably won't pursue further until some refactoring of the whole semihosting code has landed, to avoid conflicts + reading through the Realm Management Extension documentation: there's a Linaro Kernel Working Group sprint in Cambridge next week, and possible QEMU RME support is on the agenda + back before QEMU 6.0 we tried to fix a bug where QEMU always provided 4 PMU counters, not the number the emulated CPU really has. We had to revert that change before the 6.0 release, but then forgot to go back and revisit it afterwards. Alex reminded me of it this week, so I rebased it, fixed the problem that meant it got reverted, and sent it out for review. * QEMU-422 [QEMU Arm Neoverse V1 vCPU for TCG] + sent patch implementing FEAT_IDST + next up: FEAT_DoubleFault (likely a no-op for us, as we don't ever have physical SErrors) -- PMM

[ACTIVITY] Report for week #18

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging * Continued working on the testsuite regressions introduced by my code. - Currently investigating a crash that happens when for some reason gdbserver thinks that the kernel doesn't support SVE and crashes while building the internal representation of the regular vector registers. # Misc - Attended Google's Fuchsia boot camp. -- Thiago

[ACTIVITY] report week ending 6 May

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] + tracked down the UEFI crash with KVM on AArch64 to a combination of (a) host system was heterogenous and user hadn't restricted QEMU to only running on one set of cores and (b) QEMU silently throws away the error it gets from KVM in this situation, resulting in most things seeming to work except that vcpu power on/off state isn't written to KVM and so the guest starts with all vcpus running instead of just the primary. We should really improve the error handling, but I worry that that might break previously functional setups... + tidied up some patches I wrote while doing the GICv4 work that fix an odd inconsistency in our GIC emulation where we correctly implement the right number of virtual priority bits for the CPU but always provide 8 bits of physical priority regardless of what the real CPU implementation should have, and sent them out for review + usual code review and pullreq management * QEMU-422 [QEMU Arm Neoverse V1 vCPU for TCG] + Implemented support for FEAT_S2FWB and sent patches to the list + Next up is probably FEAT_IDST (ID space trap handling) -- PMM

Hello Linaro Toolchain Working Group. clang-aarch64-sve-vls-2stage builder is red for about a month. Is anybody looking at the issue? Thanks Galina

[ACTIVITY] Report for week #17

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging * Continued working on the testsuite regressions introduced by my code. - Realised that gdbserver uses “thread->tdesc != NULL” as a proxy of whether it has already attached to the inferior process. My change to track the target description per-thread instead of per-process invalidated this equivalence. Fixed a few places to use “proc->attached” instead, which is the direct way of testing that condition. - Now looking into an issue with gdbserver loading libthread_db.so. # Misc - Reviewed Tom Tromey's “[PATCH 00/36] C++-ify breakpoints” patch series¹. Spotted one bug. -- Thiago ¹ https://sourceware.org/pipermail/gdb-patches/2022-January/185256.html msgid:20220118194007.2853108-1-tom@tromey.com

Progress: * UM-2 [QEMU upstream maintainership] + investigating a bug report about the guest UEFI crashing on startup when using KVM on AArch64 with an SMP guest (sadly I haven't been able to repro it myself thus far) * QEMU-422 [QEMU Arm Neoverse V1 vCPU for TCG] + audited code to check we can enable FEAT_TTL in QEMU (ie we ignore the new TTL hint field in TLB invalidate operations) + audited code to check we can enable FEAT_BBM level 2 in QEMU (our TLB implementation never allows multiple clashing TLB entries) + audited code to check we can enable SMMUv3.2-BBML2 in our SMMUv3 (our SMMU TLB does allow multiple entries but will always select the one for the lowest level and ignore the others) + sent patches to advertise FEAT_TTL, FEAT_BBM, SMMUv3.2-BBML2 in CPU and SMMU ID registers -- PMM
