Hi, This series of patches to kvm-unit-tests add a regression test for APICv and some APIC pass-through tests. Patches 1-4 moves IOAPIC/APIC related utilities to x86 lib and define new APICv related VMCS definitions. Patch 5 adds a unit-test for the bug fixed in commit "KVM: nVMX: Do not load EOI-exitmap while running L2". This is a regression test that verifies that vmcs02->eoi_exit_bitmap is not overridden with vmcs01->eoi_exit_bitmap as a result of L1 IOAPIC scan request. Patches 6-7 add unit-tests for L1 LAPIC/IOAPIC pass-through to L2. The first test verfies that an asserted irq-line raise a level-triggered interrupt directly from L1 IOAPIC to L2 and sets L1 IOAPIC RTE remote_irr. Then, L2 performs EOI directly to L1 LAPIC which gets broadcasted to L1 IOAPIC and test verifies that indeed L1 IOAPIC RTE remote_irr is now cleared. The second test does almost the same as the first except the initial configuration of IOAPIC RTE happening from CPU1 while CPU0 is running L2. This is a regression test that verfies that vcpu->arch.ioapic_handled_vectors is updated correctly while vCPU is running L2 and is running with LAPIC/IOAPIC pass-through. Regards, -Liran Alon
