SYNOPSIS

void drm_vblank_off(struct drm_device * dev, unsigned int pipe);

ARGUMENTS

dev

DRM device

pipe

CRTC index

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.
