Progress: * QEMU-623 [Nested Virtualization Emulation] - Progress on debugging: fixed last week's bugs, and can now get the outer kernel to boot a middle kernel which boots an inner kernel. Unfortunately the inner kernel boot hangs during init of the PF_NETLINK subsystem, when it hits a prefetch abort due to a permissions check failure in the stage 2... - tidied up a lot of the bugfix fixup patches I had in my patchstack and merged them into the correct patches; they would be quite close to ready to send out if not for the bug I'm chasing down. -- PMM

Re: [Linaro-TCWG-CI] gcc-14-5673-g33c2b70dbab: FAIL: 1 regressions: 8 progressions on aarch64

by Thiago Jung Bauermann

Hello Tamar, It looks like this failure happens because qemu-aarch64 segfaults when trying to run the testcase binary: Running on qemu: timeout -k 30s 330s setarch x86_64 -R qemu-aarch64 -cpu any -R 0 -L /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/destdir/x86_64-pc-linux-gnu/aarch64-linux-gnu/libc ./mask_struct_load_3_run.exe spawn [open ...] timeout: the monitored command dumped core FAIL: gcc.target/aarch64/sve/mask_struct_load_3_run.c execution test Which would be a QEMU bug. I'm working on reproducing it and will report there if appropriate.

[ACTIVITY] report week ending 1 Dec

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - Sent a pullrequest for this week's rc - Sent a patch which disables SME if SVE is disabled, since QEMU currently asserts if you try to use that combination. * QEMU-623 [Nested Virtualization Emulation] - Mostly working through debugging issues in my FEAT_NV/FEAT_NV2 emulation. I can get the inner guest kernel to boot up to the point where it tries to 'eret' and the outer kernel thinks that's an invalid exception return. More debugging scheduled for next week... -- PMM
