CRTC in question
Overview
Drivers can use this function to shut down the vblank interrupt handling when disabling a crtc. This function ensures that the latest vblank frame count is stored so that drm_vblank_on can restore it again.
Drivers must use this function when the hardware vblank counter can get reset, e.g. when suspending.
This is the native kms version of drm_vblank_off.
