Progress:
* UM-2 [QEMU upstream maintainership]
- sent patches that re-sync our defined set of usermode hwcap bits
and ID register bitmasks with what the Linux kernel currently has
- code review
* QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG]
- FEAT_HBC: wrote and sent patch for this very simple feature
- FEAT_MOPS: rolled v2 patchset based on review feedback
* QEMU-486 [Update QEMU device models for FEAT_RME]
- Looked at the SMMU spec to see (a) what realm-management
related changes it needs and (b) where we are on the
implementation of other features. Closed a few stale
JIRA issues for features we've already implemented.
- sent a patchset that advertises that we support SMMUv3.1-XNX
(this is a no-op for our implementation)
- investigated what the "expected" setup is for enforcing GPT
checks on the GIC/ITS. Current front-runner is "the SMMU that's
already in the system provides 'GPC checks only' for the
accesses from these devices, as well as stage1/stage2 + GPT
checks for PCI etc devices" (the term in the SMMU spec rev F.a
is for a GPC-checks-only client device is "NoStreamID device")
