[kvm-unit-tests PATCH] x86: hyperv_synic: Hyper-V SynIC test
Hyper-V SynIC is a Hyper-V synthetic interrupt controller.
The test runs on every vCPU and performs the following steps:
* read from all Hyper-V SynIC MSR's
* setup Hyper-V SynIC evt/msg pages
* setup SINT's routing
* inject SINT's into destination vCPU by 'hyperv-synic-test-device'
* wait for SINT's isr's completion
* clear Hyper-V SynIC evt/msg pages and destroy

[kvm-unit-tests PATCH] x86: hyperv_synic: Hyper-V SynIC test
...ed in IRR can be injected
by the processor, and the auto-EOI behavior will be skipped.
The solution is to have userspace enable KVM_CAP_HYPERV_SYNIC through
KVM_ENABLE_CAP, and modify vmx.c to not use apicv on VMs that have it
enabled. This requires some changes to the callbacks that only work if
enable_apicv or !enable_apicv:
if (enable_apicv)
kvm_x86_ops->update_cr8_intercept = NULL;
else {
kvm_x86_ops->hwapic_irr_update = NULL;
kvm_x86_ops->hwapic_isr_update = NULL;
kvm_x86_ops->deliver_posted_interrupt = NULL;...
