[PATCH RFC 0/3] Add virtio-gpu modifiers support

[Tina Zhang]

This patchset introduces the modifiers support to virtio-gpu. 

This RFC version tries to add a new virtio-gpu command to let front-end driver
query the modifiers' info from the backend. Besides, the front-end driver
may also need a new drm helper function to add the supported modifiers to a
plane as its properties and allow fbs to use modifiers on that plane.

Tina Zhang (2):
  drm: Add drm_plane_add_modifiers()
  drm/virtio: Add modifier support

Vivek Kasireddy (1):
  drm/virtio: Include modifier as part of set_scanout_blob
