Macro Definition Documentation

DRM_CRTC_HELPER_VBLANK_FUNCS

#define DRM_CRTC_HELPER_VBLANK_FUNCS

Value:

    .atomic_flush = drm_crtc_vblank_atomic_flush, \
    .atomic_enable = drm_crtc_vblank_atomic_enable, \
    .atomic_disable = drm_crtc_vblank_atomic_disable

DRM_CRTC_HELPER_VBLANK_FUNCS - Default implementation for VBLANK helpers

This macro initializes struct &drm_crtc_helper_funcs to default helpers for VBLANK handling.

DRM_CRTC_VBLANK_TIMER_FUNCS

#define DRM_CRTC_VBLANK_TIMER_FUNCS

Value:

    .enable_vblank = drm_crtc_vblank_helper_enable_vblank_timer, \
    .disable_vblank = drm_crtc_vblank_helper_disable_vblank_timer, \
    .get_vblank_timestamp = drm_crtc_vblank_helper_get_vblank_timestamp_from_timer

DRM_CRTC_VBLANK_TIMER_FUNCS - Default implementation for VBLANK timers

This macro initializes struct &drm_crtc_funcs to default helpers for VBLANK timers.
