This needs both host and guest side changes btw. Guest side patch is in drm-misc (a3b815f09bb8) and should land in the next merge window. Host side patches are here: https://git.kraxel.org/cgit/qemu/log/?h=sirius/virtio-gpu-iommu Should also land in the next qemu version. cheers, Gerd _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
