Progress:
* UM-2 [QEMU upstream maintainership]
- Joint Linaro/Arm meeting on the Realm Management Extension (RME).
Mostly this was "how the software stack is going to work"; some
useful discussion on how this intersects with QEMU, both as a
potential emulation platform for software development and also
as the VMM for a realm-using KVM virtual machine.
- Kicked off a discussion thread on getting rid of the last parts
of our "ad-hoc CI" this release cycle. The main thing that's
not yet handled by Gitlab CI is FreeBSD and NetBSD hosts.
We might be able to do this if we can find an x86 Linux machine
to act as a gitlab runner (it needs to be able to run guest
BSD VMs).
* QEMU-422 [QEMU Arm Neoverse V1 vCPU for TCG]
- Several small features have now made it upstream so those
subtasks have been closed out
- Looking at FEAT_RASv1p1 and FEAT_DoubleFault. The first of these
is easy because we only model the minimal "no error records"
RAS: I think we can simply bump the ID register fields to
indicate support. The second is a little bit more interesting
because the new SCR_EL3.EASE bit means we suddenly have a
source of physical SErrors (from synchronous external aborts)
when we previously could not have any...
