Not that it's a bad idea, but why do you need SIMPLEDRM? I found that the existing kernel works with QEMU's -display virtio-gpu-pci, but you just don't see anything between GRUB and pivot root, presumably because the module is not in the initrd.

I also wonder why CONFIG_EFI_FB isn't enough on arm64. That's what amd64 normally uses given that we don't pass -device virtio-vga there.

made some tests and verified the minimal patch, and it seems that DRM and VIRTIO_GPU is needed at the same time (makes sense as they are in the same config tree).
