Subject: Re: [PATCH] Add virtio gpu driver.

Hi,

The virtio-gpu driver doesn't matter much here, it doesn't use it
anyway.

Yes, vgabios code needs to know. Currently it has bar #2 for the vga
framebuffer bar hardcoded. It's 16bit code. I don't feel like making
the probing more complicated ...
cheers,
Gerd
