Progress:
* VIRT-65 [QEMU upstream maintainership]
+ respun the QEMU side of the "fix 32-bit-guest readdir of
ext4 filesystems on a 64-bit host" work to match Linus Walleij's
most recent kernel patch.
+ code review (actually emptied my queue for the first time in forever):
- patchset adding some missing devices to MPS2 boards
- another round of RTH's MTE patchset (now fully reviewed and ready to go in)
- SMMUv3.2 range-invalidation support patchset from RedHat
- RTH's implementation of the kernel MTE ABI for QEMU linux-user
+ had a look at some of the lurking Coverity issues
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ fp16 support: started by working out risu patterns for all the
affected instructions so we have a means for testing the changes.
+ implemented a handful of fp16 insns; plan to back-burner this for
a little while as it's not going to be complete before we freeze
for QEMU 5.1, so work like reviewing the MTE patchset and other
for-5.1 efforts will take priority.
NB: on holiday next week

Progress:
* VIRT-65 [QEMU upstream maintainership]
+ code review:
- a fix for an A9 global timer device bug
- imx_fec ethernet bugfixes/cleanups
- SD card emulation bugfixes/cleanups (including a CVE fix)
- sm501 graphics card minor fixes
- implementation of qemu_init_exec_dir() for OSX
- patchset adding some missing devices to MPS2 boards
- RTH's v7 MemTag emulation series (this was a big one, took most of
a couple of days to work through)
+ sent docs patch deprecating our tilegx port
+ discussion about what exactly target code has to do
for icount support; wrote some patches to remove some 'gen_io_end()'
calls that turn out to be no-longer-necessary
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ completed the neon decodetree conversion and sent the last batch
of patches out for review; plan to start on fp16 support next
NB: have recorded my maintainership work under the old VIRT-65
for now; not yet clear when/which jira issue to use in the new UM-*
hierarchy.
thanks

* Training all week
== Progress ==
* GCC upstream validation:
- reported a few regressions
- enabled sending of some validation results to gcc-testresults mailing-list
* GCC:
- PR94743 (IRQ handler and Neon registers): No feedback yet.
* misc:
- infra fixes / troubleshooting / reviews
- cleanup of hal lib to run benchmarks on stm32
== Next ==
* PR94743
* GCC/cortex-M testing improvements & fixes
* cortex-m benchmarking
* FDPIC GDB
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ Good progress with the neon decodetree conversion this week -- now feels
like it's nearly done. Wrote and sent out another couple of patchsets for
review. The only remaining insns to convert are the 2-reg-misc grouping.
Have made a start on that; hope to get the final part of the conversion
out for review next week.
thanks

(0.5 day off)
== Progress ==
* GCC upstream validation:
- scripts updates and cleanup for cortex-m33 with qemu-system-mode
- investigated a random error with a C++ testcase under qemu-aarch64
since I upgraded to qemu-5.0.
- reported a few regressions
- fixed cross-build of GCC after C++11 upgrade, looked at fixing
native builds (different problem), but someone had already posted the
same fix during the week-end
* GCC:
- PR94743 (IRQ handler and Neon registers): No feedback yet.
* misc:
- infra fixes / troubleshooting / reviews
- looking at cortex-m benchmarking harnesses. Updated docker images to
include openocd and checked I could connect to the board from a docker
container.
- helping test Dejagnu new master branch in preparation for next stable release
== Next ==
* training next week
