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.

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...

Hello,
# TCWG CI
- Implemented increasing testsuite timeout for each testsuite try in GDB
check jobs. Sent a Gerrit review request for it but then found out that
it makes armhf jobs take a lot longer, so abandoned it.
# Community
- Finished reviewing SME patches for GDB and gdbserver.

Progress:
* UM-2 [QEMU upstream maintainership]
- some bits and pieces for release
- code review, notably:
+ raspberry pi 4 support patchseries (a big 44-patch set)
+ Xilinx Versal CFI support patches
* QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG]
- more work on FEAT_MOPS: tested my memset implementation, and
fixed various bugs. Still no MTE tag checking support.

Hello,
# TCWG CI
- CI Babysitting: Worked on two regressions detected at the end of last
week.
- Enabled precommit testing for GDB patches.
# Misc
- Reviewing SME patches for GDB and gdbserver.

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

Hello,
# TCWG CI
- Babysat the CI: Investigated 9 regressions in GCC, 2 in GDB, 1 in LLVM
and 1 in glibc. Reported 4 in GCC (GNU-855, GNU-857, GNU-858 and
GNU-859). 3 of which are fixed and another has a tentative fix.
- Reviewed a couple of Gerrit requests.

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...
