# This file lists graphic devices that don't have a DRM driver and fall back to
# a frame-buffer one instead. Since commit 6260d28b8a, frame-buffer devices are
# no more considered as graphical capable.
#
# The matches have the 'fb' prefix to make sure that only the framebuffer
# device, and not the (parent) PCI device, is tagged with 'master-of-seat'.

# In some HyperV VMs, the video device only can be recognized by a vmbus id.
# So we should add a vmbus id for HyperV Video device.

# This id is extracted from Linux kernel's hyperv.h
