[PATCH v2 0/2] virtio_gpu driver and relevant fix

[Jiaxun Yang <jiaxun.yang@flygoat.com>]

Hi all,

This series added support for virtio-gpu device, it has been
tested on QEMU riscv64 and aarch64.

I also fixed a problem in EFI GOP so it works with EFI applications
as well.

There is a problem remaining. virtio_init() is being called too
late to allow virtio-gpu to be selected as a vidconsole. My current
appraoch is to register virtio_init in init_sequence_r, just after
pci_init. Is this a viable approach? Should I introduce a config
like CONFIG_VIRTIO_INIT_R to allow it to be selected by boards?

Thanks
