Subject: [GIT PULL] KVM/arm64 fixes for 7.4, take #1
Date: Tue, 27 Oct 2026 14:34:24 +0000 [thread overview]
Message-ID: <20261027143424.2732449-1-maz@kernel.org> (raw)
Paolo,
Here's the first set of KVM/arm64 fixes for 7.4, most of which have
been brewing for some time. Of note: a couple of fixes for mismerges
in the initial kvmarm-7,4 pull request, fixes for the publication of
IN/OUTSIDE_GUEST_MODE, and nesting for vcpu pausing. The rest is a
bunch of cleanups for nonsensical configurations and some more pKVM
fixes. I have already started queuing more fixes, so it is likely that
I'll be back next week with a similar email.
Note that this is on top of the initial pull-request that you sent to
Linus, so hopefully conflict free.
Please pull,
M.

Merge branch kvm-arm64/misc-fixes-7.4-1 into kvmarm-master/fixes (2026-10-26 10:57:37 +0000)
----------------------------------------------------------------
KVM/arm64 fixes for 7.4, take #1
- Fix a couple of embarrassing merge mistakes in kvmarm-7.4
- Cleanup the HCR_EL2 bit fields to exclusively use the generated
definitions, fixings a nasty regression introduced in 6.16, where
barriers were not upgraded from NSH to ISH anymore
- Fix publication of state when a vcpu is forced out of the guest
- Let vcpu pausing nest correctly
- Sanitise ID_AA64MMFR3_EL1.S1P[IO]E to follow the rules of the architecture
- Don't warn on SMCCC filter reserved range allocation failure
- Prevent GICv5 and TLBI hypercalls to be used from the host when pKVM
is active
- Enforce that only GICv3 guests are supported for pKVM
- Don't try to access GICv5 EL2 sysregs from EL1
- Compute architectrally correct values for ID_AA64MMFR3_EL1.S1P[IO]E
by checking the feature dependencies
- Require matching VGIC and ITS model
- Cleanup TRACE_REMOTE dependencies
- selftests: Skip unwritable ID fields in the failed-run test
- Move pkvm_selftests() after all CPUs have initialized EL2
- Fix random comments
----------------------------------------------------------------
