From: Sean Christopherson <sean.j.christopherson@xxxxxxxxx> Return true for kvm_vcpu_has_events() if the vCPU has a pending APICv interrupt to support TDX's usage of APICv. Unlike VMX, TDX doesn't have access to vmcs.GUEST_INTR_STATUS and so can't emulate posted interrupts, i.e. needs to generate a posted interrupt and more importantly can't manually move requested interrupts into the vIRR (which it also doesn't have access to).
