Progress:
* VIRT-65 [QEMU upstream maintainership]
+ Got a v6 series sent to the list of the conversion of QAPI
doc-comments into rST/Sphinx. This took most of the week,
following Markus' detailed review on the v5 (and involved
some wrestling with Meson). Optimistic that this can get into
master now...
thanks

VirtIO Portability Demo ([STR-13])
==================================
- continue to debug nouvaue issues on latest kernel
- need to ESC/reset to EFI until framebuffer comes on
- seems ok with Debian 5.6.14-2~bpo10+1
- but not vanilla 5.6.14 or above
- need to track down kernel differences
- did some poking into getting Xen up on Debian
- seems multiboot not the way, got a bit further but need a debug
build

Progress:
* VIRT-65 [QEMU upstream maintainership]
+ usual maintainer stuff
+ started a rebase/respin of the convert-QAPI-docs-to-Sphinx series
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ sent patchset to make QEMU handle the way M-profile and A-profile
report presence of fp16 differently in their ID registers
thanks

[ Sorry it's a bit late. ]
[VIRT-327 # Richard's upstream QEMU work ]
Send out tcg patch queue.
Prototype a disassembler using llvm. Not ideal.
If we proceed with this further, we should probably
schedule time for it, because the job is not small.
Updating the capstone submodule; a couple of rounds
converting that to meson.

== This Week ==
* GNU-659 (calculix)
- Comparing code-gen of hoisting region doesn't show many more extra stores
- Came up with two heuristics, which "fix" the issue, but aren't very general.
* LLVM-611
- D79785: Created fix for expensive checks issue, and posted on llvm-dev
- D87430: Posted patch for adding heuristic to LowerCall.
== Next Week ==
- Continue ongoing tasks
Hello Linaro Toolchain Working Group,
Do you plan to bring linaro-tk1-03 back online soon?
If not, I'll remove it from the LLVM buildbot this Friday.
Thanks
Galina
[VIRT-349 # QEMU SVE2 Support ]
Continuing the testing vs armie.
[VIRT-327 # Richard's upstream QEMU work ]
* More microblaze cleanup, including a check-acceptance
regression fix from the first pull. Ho hum.
* Patch review, queue is empty again.
* Old patch queue cleanup,
Fixed some gvec bugs affecting 32-bit x86;
testing vs aa32 risu.
r~
== This Week ==
* GNU-659 (calculix LTO regression)

to build-bot failure with expensive checks turned on.

Progress: (short week, three days)
* VIRT-65 [QEMU upstream maintainership]
+ sent patches to remove QEMU's support for KVM on AArch32 hosts
(which we deprecated when the kernel removed its end of the support)
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ fp16 work is now in master
+ sent patches to add support for mps2-an386 and mps2-an500
boards (Cortex-M4 and Cortex-M7 setups similar to the existing
mps2-an385 Cortex-M3 board model)
thanks

discussion on-going
- PR96769: WIP
- PR71233: missing ACLE intrinsics. I will first have to update the list

Progress:
* VIRT-65 [QEMU upstream maintainership]
+ Just the usual code review and pull request work.
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ I have all fp16 insns (both VFP and Neon) implemented now, and the
VFP patches have been reviewed. Just need to track down a few last
test failures and then I can send the Neon patches out for review.

+ We got 5.1 out the door. I think this is the first release
in the many years I've been handling them where we managed to
avoid needing an rc4.

of the QEMU build system to Meson. We managed to land that today.
+ First of the KVM Forum programme committee meetings
* VIRT-364 [QEMU support for ARMv8.1-M extensions]

I got an email and an irc ping for
http://lab.llvm.org:8011/builders/lldb-aarch64-ubuntu/builds/6924
My change has no relation to the test failure.
Flaky bots aren't allowed to send email or ping, so either make it
non-flaky or make it not send stuff.
Thanks,
Nico
