Subject: [PATCH 0/3] KVM: nVMX: A few TLB flushing fixes
Date: Tue, 16 Jun 2026 21:46:49 +0000 [thread overview]
Message-ID: <20260616214652.2157032-1-yosry@kernel.org> (raw)
Fix a couple of issues surfaced while working on TLB optimizations for
nSVM. I did not add a Reported-by tag for Sashiko, because in both
instances Sashiko did not report the problem (or the nSVM equivalent),
but it spit out a false positive that lead to finding the problems (and
I don't know how to capture that).

KVM: nVMX: Decouple INVVPID operand checks from flushing of vpid02

KVM: nVMX: Always flush vpid02 on first use
KVM: nVM: Ensure INVVPID is emulated on the correct physical CPU
