Progress:
* UM-2 [QEMU upstream maintainership]
+ had a look at adding an option to allow semihosting from
userspace (handy for some test case purposes); have a working
prototype which I used to test the FEAT_IDST patch, but
probably won't pursue further until some refactoring of the
whole semihosting code has landed, to avoid conflicts
+ reading through the Realm Management Extension documentation:
there's a Linaro Kernel Working Group sprint in Cambridge
next week, and possible QEMU RME support is on the agenda
+ back before QEMU 6.0 we tried to fix a bug where QEMU always
provided 4 PMU counters, not the number the emulated CPU really
has. We had to revert that change before the 6.0 release, but
then forgot to go back and revisit it afterwards. Alex
reminded me of it this week, so I rebased it, fixed the problem
that meant it got reverted, and sent it out for review.
* QEMU-422 [QEMU Arm Neoverse V1 vCPU for TCG]
+ sent patch implementing FEAT_IDST
+ next up: FEAT_DoubleFault (likely a no-op for us, as we don't
ever have physical SErrors)
