Hi,

What is the point? Do you want place virtio regions and vga framebuffer
in the same pci bar? Why? virtio is mmio and traps into qemu on
access, whereas the vga framebuffer is memory-backed (with dirty
tracking turned on). Don't think this is a good idea, even though the
memory api would probably allow to do this.
cheers,
Gerd
