yeah vfio is still broken for the case I care about. I think there's also some questions open still about whether kvm really uses mmu_notifier in all cases correctly,IIRC kvm doesn't either.
Yep, KVM on x86 has a non-trivial number of flows that don't properly hook into the mmu_notifier. Paolo is working on fixing the problem, but I believe the rework won't be ready until 5.14. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
