Hi there, I noticed that kvm_mmu_reload() is called every time in vcpu enter, and kvm_mmu_load() is called in this function when root_hpa is INVALID_PAGE. I get confused why and when root_hpa can be set to INVALID_PAGE? I find one condition that if vcpu get request KVM_REQ_MMU_RELOAD, kvm_mmu_unload() is called to invalid root_hpa, but this condition cannot cover all occasions.
