47 * DOC: overview
48 *
49 * The CRTC modeset helper library provides a default set_config implementation
50 * in drm_crtc_helper_set_config(). Plus a few other convenience functions using
51 * the same callbacks which drivers can use to e.g. restore the modeset
52 * configuration on resume with drm_helper_resume_force_mode().
53 *
54 * Note that this helper library doesn't track the current power state of CRTCs
55 * and encoders. It can call callbacks like ->dpms() even though the hardware is
56 * already in the desired state. This deficiency has been fixed in the atomic
57 * helpers.
58 *
59 * The driver callbacks are mostly compatible with the atomic modeset helpers,
60 * except for the handling of the primary plane: Atomic helpers require that the
61 * primary plane is implemented as a real standalone plane and not directly tied
62 * to the CRTC state. For easier transition this library provides functions to
63 * implement the old semantics required by the CRTC helpers using the new plane
64 * and atomic helper callbacks.
65 *
66 * Drivers are strongly urged to convert to the atomic helpers (by way of first
67 * converting to the plane helpers). New drivers must not use these functions
68 * but need to implement the atomic interface instead, potentially using the
69 * atomic helpers for that.
70 *
71 * These legacy modeset helpers use the same function table structures as
72 * all other modesetting helpers. See the documentation for struct
73 * &drm_crtc_helper_funcs, struct &drm_encoder_helper_funcs and struct
74 * &drm_connector_helper_funcs.
