Shaoqin Huangrequested to merge
shahuang/centos-stream-9:RHEL9.6/kvmarm-rebase/RHEL-57113/v1 into main

JIRA: https://issues.redhat.com/browse/RHEL-57113

Upstream Status: up to v6.11 and fixes up to v6.12-rc5
Tested: kvm-unit-tests, kselftest, migration test.

This is the first round rebase kvm-arm up to v6.11, which contains the below series:

  1. KVM: arm64: pKVM host proxy FF-A fixes (part of them)
  2. KVM: arm64: nv: Shadow stage-2 page table handling
  3. KVM: arm64: Allow userspace to modify CTR_EL0
  4. KVM: arm64: nv: FPSIMD/SVE, plus some other CPTR goodies
  5. KVM: arm64: fix warnings in W=1 build
  6. Misc commits

Besides that, it also takes the fixes commit 4155539bc5ba ("KVM: arm64: nv: Enforce S2 alignment when contiguous bit is set") which up to v6.12-rc1.

  • 42fb33dde42b KVM: arm64: Use FF-A 1.1 with pKVM
    This commit belongs to the series 1, don't pick it because downstream doesn't support FF-A 1.1 (The related upstream commit is 1609626c32c4 ("firmware: arm_ffa: Update the FF-A command list with v1.1 additions")).

This KVM: arm64: Fix handling of TCR2_EL1 series can be taken by kvm-arm rebase but since it depends on the arm64 rebase, so will pick them in the second round when the arm64 rebase being merged.

  • 838d992b8448 KVM: arm64: Convert kvm_mpidr_index() to bitmap_gather()
    Don't pick this commit since downstream doesn't support bitmap_gather().
