drm_crtc_vblank_reset — reset vblank state to off on a CRTC
void drm_crtc_vblank_reset ( | struct drm_crtc * drm_crtc) ; |
Drivers can use this function to reset the vblank state to off at load time.
Drivers should use this together with the drm_crtc_vblank_off
and
drm_crtc_vblank_on
functions. The difference compared to
drm_crtc_vblank_off
is that this function doesn't save the vblank counter
and hence doesn't need to call any driver hooks.
