[PATCH 0/3] KVM: x86: Convert nested ops to static calls

From: Sean Christopherson

Date: Thu Jun 25 2026 - 19:39:13 EST


Convert nested_ops to use static calls, mainly because the nested ops are
bizarrely different than the x86 and PMU ops, and the kvm_x86_ops.nested_ops->
code is an eyesore (IMO). I haven't bothered to do any performance testing.

Sean Christopherson (3):
KVM: x86: Reject nested CAP enablement if nested virtualization is
disabled
KVM: x86: Add static calls for nested virtualization ops
KVM: x86: Move nested_ops out of kvm_x86_ops, to global kvm_nested_ops
