From e90e51d5f01d2baae5dcce280866bbb96816e978 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 30 Nov 2021 07:36:41 -0500 Subject: KVM: VMX: clear vmx_x86_ops.sync_pir_to_irr if APICv is disabled There is nothing to synchronize if APICv is disabled, since neither other vCPUs nor assigned devices can set PIR.ON.
