Progress (short week, holiday and recovering from covid...):
* UM-2 [QEMU upstream maintainership]
* 8.0 release related work rumbles on
* debugged and fixed a regression caused by my work on HSTR_EL2 traps
* QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG]
* implemented FEAT_PAN3 (and fixed a minor bug in
syndrome reporting that I noticed in the process)

Hello,
[GNU-796] Stabilize GDB testsuite results in the CI:
- Enabled gdb.gdb/unittest.exp in fast_check_gdb job. It should be
stable now that tcwg-jade-02's kernel has been upgraded.
- Enabled bisections for check_gdb jobs.
- Implemented Maxim's idea to handle GDB testsuite's tests that can FAIL
but are silent when they pass (i.e., the "gdb_test -nopass"
statements).
[GNU-767] Support changing SVE vector length in remote debugging
- Back in February I upstreamed a couple of preparation patches and
Pedro noticed an unintended change in behaviour that can affect a
corner case, so I am working on a fix for that now.

Hello,
[GNU-796] Stabilize GDB testsuite results in the CI:
- Finished implementing ABE's support for rerunning failed tests using
Maxim's idea of leveraging validate_failures.py to determine which
tests need to be rerun. Submitted v3 and v4 versions, and committed
v4.
- Investigated why tcwg-abet-tested jobs have been failing in the CI.
Found out that Jenkins sets a bogus core.hooksPath in the git repo
config. Submitted and merged a gerrit request fixing the problem.
- Investigated why cross-build gdbserver needs GMP and MPFR (and is thus
failing to build) in tcwg-gnu-build jobs. Submitted Gerrit review
request to fix it.
- Started looking into why re-enabling GDB testsuite parallelism makes
it run fewer tests.

Progress:
* UM-2 [QEMU upstream maintainership]
- went through and made estimates for a pile of JIRA tasks
relating to implementing features we're missing to get to ARMv9.4
- diagnosed why --enable-werror wasn't affecting warnings from
the kerneldoc docs generator, and sent a patch fixing it
- some bug triage, looking for issues that ought to be fixed for 8.0
- fixed a division-by-zero bug in the cadence UART model
- fixed a documentation markup mistake that made the docs look odd
- investigating/fixing some more CI failures
- minor bits of travel/conference related admin

Hello,
[GNU-796] Stabilize GDB testsuite results in the CI:
- Submitted and merged a couple of review requests removing obsolete CI
jobs related to release automation and release regression detection
- Finished version of scripts that have most of the logic for rerunning
testsuites in ABE. Submitted as a review request. Addressed review
comments and submitted v2.
- Maxim found out a way to simplify the logic of determining whether a
new testsuite run is warranted by using validate_failures.py, which
I'm now implementing.

Progress:
* UM-2 [QEMU upstream maintainership]
- Softfreeze was this Tuesday; lots of wrangling of pull requests
- Code review; last arm pullreq before softfreeze
- various admin type bits and pieces

Hello,
[GNU-796] Stabilize GDB testsuite results in the CI:
- Moved most of logic to rerun failed tests from tcwg_gnu-build.sh to
Abe and a new script based on the sum file parser of
compare_dg_tests.pl. The new script creates a "merged" sum file from
all the runs. Currently changing Abe to make use of it.
- Did a few cleanups in compare_dg_tests.pl as I was going through its
code. Also added KFAIL status support to it, which the GDB testsuite
needs.
- Removed a few obsolete CI jobs which came out of the woodwork when I
merged the compare_dg_tests.pl cleanups.
