Detailed Description

struct drm_connector_hdmi_funcs - drm_hdmi_connector control functions

Member Data Documentation

audio

struct drm_connector_infoframe_funcs drm_connector_hdmi_funcs::audio

@audio:

Set of callbacks for handling the Audio InfoFrame. These callbacks are optional, but they are required for drivers which use drm_atomic_helper_connector_hdmi_update_audio_infoframe().

avi

struct drm_connector_infoframe_funcs drm_connector_hdmi_funcs::avi

@avi:

Set of callbacks for handling the AVI InfoFrame. These callbacks are mandatory.

hdmi

struct drm_connector_infoframe_funcs drm_connector_hdmi_funcs::hdmi

@hdmi:

Set of callbacks for handling the HDMI Vendor-Specific InfoFrame. These callbacks are mandatory.

hdr_drm

struct drm_connector_infoframe_funcs drm_connector_hdmi_funcs::hdr_drm

@hdr_drm:

Set of callbacks for handling the HDR DRM InfoFrame. These callbacks are mandatory if HDR output is to be supported.

read_edid

const struct drm_edid *(* drm_connector_hdmi_funcs::read_edid) (struct drm_connector *connector)

@read_edid:

This callback is used by the framework as a replacement for reading the EDID from connector->ddc. It is still recommended to provide connector->ddc instead of implementing this callback. Returned EDID should be freed via the drm_edid_free().

The @read_edid callback is optional.

Returns: Valid EDID on success, NULL in case of failure.

spd

struct drm_connector_infoframe_funcs drm_connector_hdmi_funcs::spd

@spd:

Set of callbacks for handling the SPD InfoFrame. These callbacks are optional.

tmds_char_rate_valid

enum drm_mode_status(* drm_connector_hdmi_funcs::tmds_char_rate_valid) (const struct drm_connector *connector, const struct drm_display_mode *mode, unsigned long long tmds_rate)

@tmds_char_rate_valid:

This callback is invoked at atomic_check time to figure out whether a particular TMDS character rate is supported by the driver.

The @tmds_char_rate_valid callback is optional.

Returns:

Either &drm_mode_status.MODE_OK or one of the failure reasons in &enum drm_mode_status.
