NAME¶
drm_crtc_vblank_off - disable vblank events on a CRTCSYNOPSIS¶
void
drm_crtc_vblank_off(struct drm_crtc * crtc);
ARGUMENTS¶
crtcCRTC in question
DESCRIPTION¶
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.AUTHORS¶
