Would there be any objection to adding a second MMIO BAR to qemu-vga which mirrors the bochs magic VBE ports ? Support for IO space is optional in PCIe and can be problematic on some architectures, it would be nice to be able to program the card entirely using mmio. Once done, I'd like to look into doing a qemudrmfb similar to the cirrus one that pretty much gives you generic KMS support (with RandR) on top of vga-pci. This would have the advantage of potentially lifting the pitch and size limitations that plague cirrus. Cheers, Ben.
