[ACTIVITY] report week ending 21 Oct

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - Usual code review and patch handling work - Spent a couple of days investigating a long-standing intermittent test case failure booting a kernel on the raspberry pi. This turned out to be caused by two linked bugs: - the test framework unhelpfully disconnects immediately from the guest serial console when the test ends, rather than staying connected until the QEMU process exits to capture all the output - QEMU's socket chardev loses data when the remote end closes the connection if the guest UART hasn't read all of it So the test was failing because the guest sometimes only saw the 'h' of the final 'halt' command the test sent... - Investigated and fixed a regression caused by some of last week's reset patches. (Turns out the patch to fix it had been sent back in 2021 but we accidentally dropped it on the floor. Oops.) thanks -- PMM

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - Started looking again at QEMU's rather messy set of reset related APIs. Dug out the half-a-plan I wrote up a long time back and refreshed my memory of what I was hoping we might be able to do. - As an initial step, wrote some patches to get rid of uses of several deprecated reset-related functions so that I only have to think about one set of functions and not two... -- PMM

[ACTIVITY] Report for weeks #37, #39 and #40

by Thiago Jung Bauermann

Hello, I haven't sent a report since week #36. For that reason, this report covers three weeks. # [GNU-796] Stabilise GDB testsuite results in the CI - Implemented CI job to run fast GDB tests based on the list from Sourceware's builder. Submitted Gerrit change requests for jenkins-scripts and ci/job/configs. - Posted Gerrit change request for jenkins-scripts with an improvement to tcwg_gnu-build.sh to use a default path for the artifacts file if one isn't given on the command line. # [GNU-767] Support changing SVE vector length in remote debugging - Started incorporating suggestions from Luis' review of the patches. # Community participation - Reviewed mailing list patch “[PATCH v3] gdb/arm: Handle lazy FPU register stacking” - Attended GNU Tools Cauldron 2022. -- Thiago

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - sent out patch which adds a retry-on-EINTR loop to KVM_CREATE_VM ioctls - wrote up the draft of the minutes for the QEMU Summit for review - more code review and pullrequest collation (notably the Arm v8R support patchset) * QEMU-471 [QEMU ARM v9.0 Baseline CPU for TCG] - read up on the remaining unimplemented features under this epic; closed out one we'd already implemented, and wrote up enough detail on the others to be happy with putting them all into the current sprint (they're all small features) - started looking at FEAT_GTG thanks -- PMM
