Hello,
# [GNU-767] Support changing SVE vector length in remote debugging
- Fixed a regression found when preparing the new patches. Rebased on the
current mainline branch and continued preparing patches for upstream
submission.
# Misc
- Found a minor problem with a script in upstream GDB. Submitted and
committed a quick patch¹ to fix it.

Progress:
* UM-2 [QEMU upstream maintainership]
- another round of patch review and a pull request
* QEMU-471 [QEMU ARM v9.0 Baseline CPU for TCG]
- Made some useful progress with the FEAT_FGT implementation
-- PMM
* A couple of attempts at minimizing arm per-cpu init work.
I've posted a short/medium-term solution for the lookup issue,
so that we can re-apply Alex's CPUState unrealize patch.
* TCG patch queue flushed, including call abi reorg.
- Rebase TCGv_i128 patch set
- Rebase goto_tb race condition patch set

Progress:
* UM-2 [QEMU upstream maintainership]
- I'm now back on merging duty for the 8.0 release cycle, so some
time spent on pull request processing
- Sent pull requests with accumulated arm and reset-refactoring
patches from the freeze period
- Trying to cut down my code review backlog before the holidays
-- PMM
# [GNU-767] Support changing SVE vector length in remote debugging
- Patches to gdbserver to support changing the SVE vector length: About
halfway through implementing the new approach of sending new XML
target descriptions through the wire.
# Misc
- Experimented with using a GDB wrapper to run the testsuite. Came up
with a small patch that fixes the tests that fail when using the
wrapper.
