[PATCH v4 0/2] Add vfio dma-buf based display reset handling

[Tina Zhang]

vfio display needs to release the invalid display resource and disable
the scanout mode during guest OS reboot, otherwise bugs come out.

Thanks hang.yuan at intel.com for helping root cause the issue.

v3->v4:
 - Move dma-buf based display check into the vfio_display_reset().
   (Gerd)

v2->v3:
 - Limit vfio_display_reset to dma-buf based vfio display. (Gerd)

v1->v2:
 - remove dpy_gfx_switch_surface. (Gerd)
 - add dpy_gfx_update_full. (Gerd)

Tina Zhang (2):
  console: introduce dpy_gfx_update_full
  ui: introduce vfio_display_reset
