[kvm-unit-tests PATCH] x86: hyperv_synic: Hyper-V SynIC test
...does not perform TPR virtualization (SDM 29.1.2).
In addition (and even worse) because virtual interrupt delivery is
enabled, an auto-EOI interrupt that was stashed 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;

[PATCH 0/7] Hyper-V Synthetic interrupt controller
Hyper-V SynIC (synthetic interrupt controller) device
implementation.
The implementation contains:
* msr's support
* irq routing setup
* irq injection
* irq ack callback registration
* event/message pages changes tracking at Hyper-V exit
* Hyper-V test device to test SynIC by kvm-unit-tests
