[ Linux on ARM mini-conference ]
2 days. Some interesting stuff in the future hardware directions talks.
Helped out a bit with ABI history in the toolchain breakout session. Some good
hallway discussion, especially re record-replay on aarch64.
I should make time this weekend to produce a more complete trip report.
[VIRT-263 # ARMv8.1-VHE Virtual Host Extensions ]

[VIRT-327 # Richard's upstream QEMU work ]
Random patch review.
Updated some aa32 vfp cleanup patches; still need to
re-test and post.

Progress:
* VIRT-65 [QEMU upstream maintainership]
- sent pullreq with some of the pending rST doc conversion work
- finished the work on converting the json QAPI doc comments from
texinfo to rst, and sent out a patchset for this
- code review:
- Cornelia's patches rstifying some s390 docs
- rth's 'Reduce aa64_va_parameter overhead' patch
- a patchset fixing some minor memory leaks in timer devices
- rth's PAN/ATS1E1/UAO patchset
- sent out an arm pullreq
I seem to be currently keeping on top of the code-review queue
with about an afternoon a week spent on review, which is pleasing.
thanks

Progress:
* VIRT-65 [QEMU upstream maintainership]
- more work on rST doc conversion. I've started in on converting the
documentation that we auto-generate from doc comments in json files
(this covers QEMU's QMP protocol and a similar protocol for the
guest-agent).
I now have something that is basically the right shape and correctly
handles 'Command' and 'Object' (with 'Enum' and Alternate' and some
other corner cases still to do). Might be able to send a patchset out
next week with luck. This is I think the last major obstacle to the
rST conversion -- once it's done the rest is just simple-but-tedious
conversion of the remaining document files.
- code review:
+ aspeed 'misc fixes and extensions' patchset
+ "Stop wrongly programming GICR_PENDBASER.PTZ bit" bugfix patch
+ KVM 'adjust virtual time when VM starts/stops' patchset
+ last few unreviewed patches in RTH's VHE patchset respin

== Progress ==
* BFD Linker:
- GNU-629: non-contiguous memory support: fixed bugs found when
running the testsuite with the new option activated. Adding warnings
to help understand potential placement changes.
* GCC:
* GCC-9: continued work for validation of -mpure-code on v6m: the
patch applies cleanly in the branch, but there are unexpected failures
compared to trunk. Debugging.
* GCC upstream validation:
- reported a couple of failures/regressions
* misc:
- infra fixes / troubleshooting / reviews
== Next ==
* Binutils: GNU-629: support non-contiguous memory regions in linker
* GCC-9: continue work for validation of -mpure-code on v6m
== Progress ==
* Updating lldb for the latest Morello architecture changes
* Started running the tests for llvm 10.0.0-rc1
== Plan ==
* Check up on the release
* More Morello

Clean up my Jira tickets so that they can be passed on or closed.
This is my last week as a Linaro assignee, will be going back to the
Arm as of next week. I've really enjoyed my time here, thank you for
having me.
Buildbots, busy week that took up most of spare time
- deploying timezone fix to containers
- a couple of weekend patches that broke Arm and AArch64 bisected and
followed up.
- difficult to track down stage-2 failure that was difficult to work
out whether there was a bug in clang, or a code-gen failure in the
backend, also made it harder to bisect. Turned out that it had caused
more easy to bisect failures in other projects and by the time I'd
found the patch it had been fixed.
[ClangBuiltLinux]
LLD's simplified interworking looks to be insufficient for the linux
kernel thumb-2 build. Got agreement with upstream on how to proceed.
Have a patch ready to send upstream.
A small amount of upstream review and bisecting some Linaro CI build
failure for the -fpatchable-functions feature in Clang-10. Looks to
have been resolved.
