[UM-2]
* Version 2 of signal trampolines,
* Version 1 of vdso,
* RFC patch set for #360 (unaligned mmio),
* Beginning on #404 (breakpoint slowdown),
- convert cris, nios2, avr to translator loop.
- translator_use_goto_tb
Both of these, working toward improving the
recognition of pc's with bp's, and avoiding
the need for any tb flushing at all.

== Progress ==
* GCC
- MVE/vectorization: committed patches for vec_pack / vec_unpack
- handling feedback on patch for PR 100757
* GCC upstream validation:
- reported a couple of regressions
== Next ==
Now leaving Linaro, hopefully I can continue to work on:
* MVE auto-vectorization/intrinsics improvements
* GCC/cortex-M testing improvements & fixes
* GDB/cortex-M
Thanks for the great time at Linaro!
Progress:
* UM-2 [QEMU upstream maintainership]
+ Usual code review and pull request wrangling (nothing major this week)
+ Added information to our documentation about what Arm architecture
features our emulation supports (we get asked this from time to time,
and users shouldn't have to dig through back issues of the Changelogs
or decipher the ID register updates in the source code...)
+ Investigated some bugs in v8.1M VLDR/VSTR sysreg detected by trying
to run some gcc test cases under QEMU: sent patches
+ KVM Forum programme committee meeting & voting on talk abstracts
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
+ Fixed various issues in the first-part-of-MVE patchset; it's now
through code review and ready to go in
+ Started looking at the logical-immediate insns
+ Progress meter: 74/210 (35%) (still)
-- PMM
[UM-2]
Upstream bugs:
#390, fix posted
#403, fix posted
#360, lots of investigation, and work on updating
a patch from 2017. I have a workable change,
which ought to be improved.
Reorg for tcg bswap opcode.
r~
Progress (short week, 3 days):
* UM-2 [QEMU upstream maintainership]
+ Code review:
+ v4 of Shashi's ITS series. I think this is getting pretty close
to good to go in now.
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
+ Completed implementation of PSR.ECI handling
+ Implemented VADDV
+ Sent out an interim patchset for early code review (55 patches,
~3400 lines, covers about 35% of the ISA)
+ Started working through the code review comments from rth
+ Progress meter: 74/210 (35%)
-- PMM
Progress (short week, 3 days):
* UM-2 [QEMU upstream maintainership]
+ Code review:
- reviewed the easy half of the "aarch64 support for osx hvf accelerator"
patchseries
- RTH's bfloat16 support series
+ Misc bugs:
- Sent a patchset fixing a compile failure reported by MS when the
'virt' board is not enabled (requires a custom local config)
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
+ Working through the details of how PSR.ECI works for resuming
half-executed insns (annoyingly awkward to implement for a subfeature
that will almost never get used...). I have most of an implementation
now but it needs a bit of new functionality in TCG ("throw away any
TCG ops we just generated and rewind to point X") which RTH hasn't
written yet :-)
+ None of that work corresponds to adding more insn patterns, so no
change on the Progress meter: 73/210 (34%)

Hi Richard,
Your patch a076632e274abe344ca7648b7c7f299273d4cbe0 appears to have broken bootstrap-O3 for 32-bit armhf. Do you have an AArch32-capable machine to reproduce/investigate this on? Let me know if not, and I'll make a proper bug report with a testcase.

Progress:
* UM-2 [QEMU upstream maintainership]
- release work: rc5 Monday, and then 6.0 final release on Thursday.
- sent a pullreq with some accumulated arm patches now 6.1 is open
- fixed a trivial bug where WFI in the usermode emulator crashed
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
- Implemented more instructions: logic ops, VCLS, VCLZ, VREV, VMVN,
VABS, VNEG, VADD, VDUP, VSUB, VMULH, and widening VLDR.
(These are all simple "always call an out-of-line helper" versions.
We'll want an optimised "we know we have no predication" version
for many of them, but I plan to do that afterwards.)
- Worked through the v8M Arm ARM identifying which insns we must
implement. There are 210 insn patterns in total, of which I have
currently implemented 23, so we can produce a rough-and-ready
progress meter: 23/210 (11%)
(There is of course work to do beyond just the insns, but they
form the bulk of it, so the meter has some utility.)

Progress:
* UM-2 [QEMU upstream maintainership]
- code review:
+ Shashi's ITS emulation patchset
+ RTH's remaining fixes for MTE
+ RTH's patchset to implement alignment checking
- release work: sadly we found a pretty nasty crasher bug at the last
minute, so we'll release rc5 on Monday and final release Thursday
(with luck)
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
- useful discussions with RTH about how to implement MVE and in
particular how to handle its various flavours of insn predication
- some progress in writing code to implement the first insn (VLDR)
thanks

Progress:
* UM-2 [QEMU upstream maintainership]
- Finished and posted patches implementing remap support for AN524
- Release work for rc3
- Sent a set of refactoring patches that split out some files we
were previously #including into translate.c so they are separate
compilation units.
- Thought a bit more about reset handling (in the course of writing
the AN524 remap patches I again ran into some of the deficiencies
of our current reset implementation; I really must take some time
this release cycle to try to improve things here...)
- Fixed bug where our AN547 board model accidentally disabled the FPU
on the Cortex-M55...
- ...and one where we were accidentally giving it an M33 rather than
an M55 !
- Respun and extended some patches from Paolo which fix our use of
QEMU and system headers in the 2 C++ files in the codebase (which
were broken by a change in new versions of glib)
- started looking at some of the for-6.1 patch review queue, which I
had been postponing in favour of for-6.0 stuff
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
- re-read the MVE portions of the v8M Arm ARM, sketched out a plan
of where to start with the QEMU implementation
thanks

It isn't a large extension, so all done. I added aarch64 simd, aarch32 neon,
and sve support all at once. I've tested it via risu vs FVP.
I've based this on my SVE2 branch, since there are some cleanups that made that
easier. I'll post patches to qemu-devel next week.

Progress (short week, 2 days):
* UM-2 [QEMU upstream maintainership]
- more release work, bug triage, etc
- started implementing the memory-remapping feature of the
AN524 FPGA image (which allows the BRAM and QSPI to be swapped
either at startup or dynamically under guest control). Some guests
(like ARM TF-M) assume the QSPI mapping.
thanks

== Progress ==
* GCC upstream validation:
- Reported minor testsuite issues (eg failures with -mabi=ilp32 on aarch64)
- re-started looking at validation for cortex-m55, realized that qemu
does not support MVE yet
* GCC
- posted further fix for testcase for PR96770
- fixed PR 99786
- committed fix for PR 99773
* Misc
== Next ==
* MVE auto-vectorization/intrinsics improvements
* GCC/cortex-M testing improvements & fixes
* Resume GDB/FDPIC work
Progress:
* UM-2 [QEMU upstream maintainership]
- tagged rc0
- various bug investigation/patches for 6.0-ish stuff:
+ machines with a 'platform bus' incorrectly treated all sysbus
devices as hotpluggable: wrote and sent patchseries
+ respin of gpex pci-host "don't fault for unmapped MMIO/PIO window
accesses" patch
+ document how to use gdbstub/gdb for a multi-cluster machine where
the clusters are different gdb inferiors
+ looked for workarounds for macos Appkit bug where Apple broke menubars
for apps that start off as console apps and programmatically switch
themselves to being GUI apps; various online suggestions don't seem
to help, except for "when app starts, force the Dock to become active
and then grab back focus 200ms later". Maybe we'll do that, but it's
pretty ugly...
thanks

== Progress ==
* GCC upstream validation:
- Small improvement to pre-commit testing scripts to allow running a
subset of the tests (and thus save a lot of time)
* GCC
- MVE autovectorization:
- vcmp support of FP types OK.
- testsuite cleanup: looking at current failures, only found issues
with tests so far. Testing several small testsuite patches is taking a
long time due to the number of configurations
* Misc
== Next ==
* MVE auto-vectorization/intrinsics improvements
* GCC/cortex-M testing improvements & fixes
* Resume GDB/FDPIC work
Progress:
* UM-2 [QEMU upstream maintainership]
- softfreeze was this week, lots of pullreq processing
- spun v2 of "fix M-profile load of PC/SP from ELF images via
memory aliases"
thanks
