[PATCH 0/2] KVM: x86: Fastpath accounting fixes

From: Sean Christopherson
Date: Thu Jun 01 2023 - 21:19:29 EST


Fix two bugs where KVM fails to account/trace exits that are handled
in the super fast fastpath. SVM doesn't actually utilize the super fast
fastpath, i.e. patch 1 only affects VMX and the bug fixed by patch 2 is
benign in the current code base.

Found by inspection, confirmed by hacking together a small selftest and
manually verifying the stats via sysfs.

KVM: x86: Account fastpath-only VM-Exits in vCPU stats
KVM: SVM: Invoke trace_kvm_exit() for fastpath VM-Exits
