o Misc
* Various meetings and discussions.
Progress:
[VIRT-198 # QEMU: SVE Emulation Support ]
Part 2 posted.
[Upstream]
Review of tb_lock removal; it's failing it's own asserts. :-/
Respin interp_dirfd patchset, now with host fd protection.
Posted an RFC for splitting up the ~5000 line do_syscall function.
[Cortex Strings]
Found two bugs in my sve string implementations.
Submitted the results to cortex-strings.
(This is the mechanism by which I plan to test the first-fault
load implementation within qemu; the testsuite tries string
operations near a page boundary.)
Beginning to incorporate feedback from Richard Sandiford.
So far strlen, strcmp, strcpy updated, but not yet reposted.

[ACTIVITY]
Upstream reviews for LLD. Trying to be more proactive here now that
there are fewer maintainers.
[TCWG-1420] Initial investigation into some proposed linker
enhancements for embedded systems
- Mostly features already implemented in proprietary linkers such as
AT and an equivalent to .any.
- Completed initial investigation with links to TI/IAR documentation,
binutils discussions.
- Some thoughts on which of the features might be implemented cleanly
enough to be upstreamed.
Pinged llvm-mc subtarget reviews (no response)
Spent some more time investigating a tiny-code model for AArch64 in an
attempt to teach myself more about LLVM.
Progress: [short week, 3 days]
* VIRT-65 [QEMU upstream maintainership]
+ code review
+ some more conversions of devices using 'old_mmio'
+ looking at trying to fix non-migrated RAM regions in various devices
* VIRT-164 [improve Cortex-M emulation]
+ wrote some minor cleanup patches (including giving a helpful error message
for attempts to use an M-profile CPU without an NVIC, rather than crashing)
+ reviewing first few patches from the micro:bit emulation GSoC students
+ reviewed and added comments on Stefan's list of tasks for
Cortex-M0 emulation
Absences:
* Aug 27 -- Sep 14: holiday
* Sep 17 -- 21: Linaro Connect (Vancouver)
* Oct 22 -- 26: KVM Forum (Edinburgh; unconfirmed)
* NB: I work a 4 day week, excluding Wednesdays
thanks
