--- Comment #50 from Anthony (anthonysanwo@googlemail.com) ---
On Windows -
0.61% [kvm_amd] [k] svm_deliver_avic_intr
0.05% [kvm_amd] [k] avic_vcpu_put.part.0
0.02% [kvm_amd] [k] avic_vcpu_load
0.14% [kvm] [k] kvm_emulate_wrmsr
Looking around that should that IOMMU was working in Linux as intended when
combined with looking at proc/interrupts and seeing interrupts when being
handled by AMD-Vi and not IRQ counters for the PCI devices I passed through.
I was working is there a difference in how Windows/Hyper-V handles IOMMU AVIC
or am I missing something that could be disabling it being activate?
Sorry for the double comment i mistakenly submitted my first comment midway
typing my full reply.
