H A Ddrm_atomic_state_helper.c42 #include <linux/dma-fence.h>
45 * DOC: atomic state reset and initialization
48 * and correct atomic software state for all connectors, CRTCs and planes
50 * suspend. One way to solve this is to have a hardware state read-out
51 * infrastructure which reconstructs the full software state (e.g. the i915
54 * The simpler solution is to just reset the software state to everything off,
58 * On the upside the precise state tracking of atomic simplifies system suspend
66 * __drm_atomic_helper_crtc_state_reset - reset the CRTC state
67 * @crtc_state: atomic CRTC state, must not be NULL
71 * values. This is useful for drivers that subclass the CRTC state.
