Progress (short week, 2 days):
* UM-2 [QEMU upstream maintainership]
- sent some small patches: fixing Coverity issues; converting a
few users of a legacy API to the new function
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
- Implemented more insns: VMUL, VSTRB/H/W, VMAX, VMIN,
VABD, VHADD, VHSUB, VMULL, VRMULH. Progress meter: 36/210 (17%)

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
