Paolo, Here's the set of KVM/arm64 updates for 6.10. No new feature exactly, but a lot of internal rework, improvements and bug fixes, However, it is pretty good to see that the Android folks are resuming the upstreaming effort after a long period of silence. As usual, details in the tag below. Please pull, M. The following changes since commit fec50db7033ea478773b159e0e2efb135270e3b7: Linux 6.9-rc3 (2024-04-07 13:22:46 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvmarm-6.10-1 for you to fetch changes up to eaa46a28d59655aa89a8fb885affa6fc0de44376: Merge branch kvm-arm64/mpidr-reset into kvmarm-master/next (2024-05-09 18:44:15 +0100) ---------------------------------------------------------------- KVM/arm64 updates for Linux 6.10 - Move a lot of state that was previously stored on a per vcpu basis into a per-CPU area, because it is only pertinent to the host while the vcpu is loaded. This results in better state tracking, and a smaller vcpu structure. - Add full handling of the ERET/ERETAA/ERETAB instructions in nested virtualisation. The last two instructions also require emulating part of the pointer authentication extension. As a result, the trap handling of pointer authentication has been greattly simplified. - Turn the global (and not very scalable) LPI translation cache into a per-ITS, scalable cache, making non directly injected LPIs much cheaper to make visible to the vcpu. - A batch of pKVM patches, mostly fixes and cleanups, as the upstreaming process seems to be resuming. Fingers crossed! - Allocate PPIs and SGIs outside of the vcpu structure, allowing for smaller EL2 mapping and some flexibility in implementing more or less than 32 private IRQs. - Purge stale mpidr_data if a vcpu is created after the MPIDR map has been created. - Preserve vcpu-specific ID registers across a vcpu reset. - Various minor cleanups and improvements.
