NAME
drm_vblank_off - disable vblank events on a CRTC
SYNOPSIS
void drm_vblank_off(struct drm_device * dev, int crtc);
ARGUMENTS
dev
DRM device
crtc
CRTC 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 legacy version of drm_crtc_vblank_off.
