[Qemu-devel] [PULL 1/1] vfio: Enable NVIDIA 88000 region quirk regardless of VGA

[Alex Williamson]

If we make use of OVMF for the BIOS then we can use GPUs without VGA
space access, but we still need this quirk.  Disassociate it from the
x-vga option and enable it on all NVIDIA VGA display class devices.
