drm_crtc_vblank_on(9) enable vblank events on a CRTC

SYNOPSIS

void drm_crtc_vblank_on(struct drm_crtc * crtc);

ARGUMENTS

crtc

CRTC in question

DESCRIPTION

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 unconditionally called in driver load code to reflect the current hardware state of the crtc.

This is the native kms version of drm_vblank_on.
