== Progress ==
* GCC upstream validation:
- reported a couple of regressions
- sent an email to discussed the preferred combinations when running
the testsuite
* GCC:
- PR94743 (IRQ handler and Neon registers): iterating. Sent updated
patch to emit a warning. Cleanup patches merged. Sent WIP patch that
saves FP regs for discussion.
* misc:
- infra fixes / troubleshooting / reviews
- looking at cortex-m benchmarking harnesses, issues with openocd
== Next ==
* GCC validation matrix updates
* PR94743
* GCC/cortex-M testing
* cortex-m benchmarking
* FDPIC GDB
Progress:
* VIRT-65 [QEMU upstream maintainership]
- Some patch review/pullreq handling. Notably, the patchset to
allow AArch64 KVM hosts to report host memory errors to guests
is now in master.
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
- Sent out v2 of the neon-decodetree conversion patches (covering
the 3-reg-same grouping); this is based on RTH's vector cleanup
patchset. Got this reviewed and into master.
- Sent out a conversion patchset for 2-reg-and-shift and
1-reg-and-immediate insn groups.
thanks

== Progress ==
* Out of office tomorrow (Friday)
* Morello - looking into some unrelated failures after a merge from upstream
* Morello - updating aadwarf spec
== Plan ==
* Out of office next Thursday and Friday
... and apologies for tomorrow's meeting.
[VIRT-344 # ARMv8.5-MemTag, Memory Tagging Extension ]
Updated the branch, both system and user.
There's a report of an assertion failure in system mode, but no testcase to go
with it. I need to ping for a devel branch with which to play.
[VIRT-349 # QEMU SVE2 Support ]
Some prerequisites merged upstream.
[VIRT-327 # Richard's upstream QEMU work ]
Review of risc-v risu patches.

(Short week, 4 days.)
Progress:
* VIRT-65 [QEMU upstream maintainership]
- Added brief documentation of some of the QEMU models of Arm
devboards, now we have a better place for this info to live
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
- Fixed https://bugs.launchpad.net/bugs/1877136 (we were not using
the right gdb XML feature for M-profile CPUs, which meant that
stack backtraces across an exception stack frame didn't work and
we didn't report the XPSR to gdb correctly)
- Started working through code review responses from rth to the
first lot of neon-decodetree patches
thanks

Short week (4 days)
== Progress ==
* GCC upstream validation:
- Added gcc-10 branch
- maybe we should agree on a common way of running the testsuite
* GCC:
- PR94743 (IRQ handler and Neon registers): iterating. Refining patch
that emits a warning (testsuite refinements...), Need to update
additional patch that actually saves the FP regs so that it takes the
D16/D32 versions into account.
* misc:
- infra fixes / troubleshooting / reviews
- looking at cortex-m benchmarking harnesses, issues with openocd
== Next ==
* GCC validation matrix updates
* PR94743
* GCC/cortex-M testing
* cortex-m benchmarking
* FDPIC GDB
