Enable vblank events on a crtc
void drm_crtc_vblank_on(struct drm_crtc * crtc);
crtc
CRTC in question
This functions restores the vblank interrupt state captured with drm_vblank_off again. Note that calls to drm_vblank_on and drm_vblank_off can be unbalanced and so can also be unconditionaly called in driver load code to reflect the current hardware state of the crtc.
This is the native kms version of drm_vblank_on.
