Progress (short week, 3 days)
* UM-2 [QEMU upstream maintainership]
+ more code review, notably the Apple Silicon hvf support, which is
nearly ready to go in
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
+ Sent out v2 of the "optimized code gen for MVE" patchset;
this now covers all the insns that have an easy optimized version.
+ Fixed a bug where we weren't correctly setting up FPSCR.LTPSIZE
when using QEMU's user-mode-only emulator
+ Wrote some code to add support for the (not yet finalized) gdbstub
XML that tells GDB that the guest CPU has MVE. This causes a GDB
with the MVE handling to crash, so one or the other of us has
got something wrong :-)
KVM Forum was this week, as a 2-day virtual conference. I felt the
programme was comparatively a bit small this year, but there were some
interesting talks. Also a BoF session on whether/how we should
consider adding Rust code to QEMU: I am pushing for (a) a clearer
medium-to-long-term vision of where we would be going and why we'd be
doing this and (b) more design-sketch type work of "what would XYZ in
rust look like", which would hopefully both (a) make the benefit/lack
thereof a bit more clear and (b) demonstrate that there are enough
people enthusiastic enough about the prospect to make it a success...
