Ilia, do you have definitive knowledge of GPUs which
a) have a different class than PCI_CLASS_DISPLAY_VGA and
b) have working DP/HDMI outputs and
c) have an integrated HDA controller?

I'm asking because get_bound_vga() in sound/pci/hda/hda_intel.c specifically
matches against PCI_CLASS_DISPLAY_VGA only. In other words, if a GPU with t=
he
three above-listed properties exists and is built into a hybrid graphics
laptop, it is currently not registered with vga_switcheroo, which would be
wrong.
