Subject: [PATCH v3 0/5] KVM: arm64: TCR_EL2 fixes, FEAT_LPA2=NI for NV
Date: Thu, 29 Oct 2026 15:37:27 -0700 [thread overview]
Message-ID: <20261029223732.103785-1-oupton@kernel.org> (raw)
I went ahead and grabbed Wei-Lin's series [1] that added TCR_EL2
sanitisation since it makes life quite a bit easier for computing an
effective TCR_EL1.
Tested on Neoverse-V2 running a guest with FEAT_E2H0.
v2 -> v3:
- Collect R-b's from Joey
- Add patch "KVM: arm64: nv: Correctly compute the effective TCR_EL1
for nVHE TCR_EL2", itself picking up fixes for forwarding missing
fields into the effective TCR_EL1 value (Fuad)
