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")
