[PATCH V3 0/4] Add infrastructure for vblank and page flip events in vkms

[Rodrigo Siqueira]

Currently, we are working to make VKMS pass in the kms_flip test (IGT).
As a result, we made a series of changes in the module with the goal to
meet some of the necessary steps required by kms_flip. This patchset
comprises all the modifications needed to make kms_flip partially pass.

Note that the patch "drm/vkms: Add framebuffer and plane helpers" add
two dummy functions related to the plane which is necessary for the
basic operation of the VKMS during the kms_flip. During the original
discussion with Daniel, he suggests removing these dummy functions [1];
however, removing these functions results in errors during the execution
of kms_flip.

Finally, this patchset is based on:
- [PATCH V2 0/5] drm/vkms: Updates to meet basic kms_flip requirements
  (https://www.spinics.net/lists/dri-devel/msg180544.html)
- [PATCH V3] drm/vkms: Add vblank events simulated by hrtimers
  (https://www.spinics.net/lists/dri-devel/msg182600.html)
