I don't think the orientation is relevant. It will always be "normal" from DP PoW after muxing, no? I'm also not sure those deatils are enough in the long run. Based on what I've understood from our graphics team guys, for example knowing if multi-function is preferred may be important in some cases. +Imre. All of that, and more, is already available in the Configuration VDO Status VDO that the we have negotiated with the DP partner. Both those VDOs are part of struct typec_displayport_data. I think we should simply supply that structure to the DRM code instead of picking those details out of it... > /** > * struct drm_tv_connector_state - TV connector related states > * @subconnector: selected subconnector > @@ -1110,6 +1132,15 @@ struct drm_connector_funcs { > */ > void (*atomic_print_state)(struct drm_printer *p, > const struct drm_connector_state *state); > + > + /** > + * @oob_hotplug_event: > + * > + * This will get called when a hotplug-event for a drm-connector > + * has been received from a source outside the display driver / device. > + */ > + void (*oob_hotplug_event)(struct drm_connector *connector, > + struct drm_connector_oob_hotplug_event_data > *data); So I would not try to generalise this like that. This callback should be USB Type-C DP altmode specific: void (*oob_hotplug_event)(struct drm_connector *connector, struct typec_displayport_data *data); Or like this if the orientation can really be reversed after muxing: void (*oob_hotplug_event)(struct drm_connector *connector, struct typec_altmode *altmode, struct typec_displayport_data *data); You can now check the orientation separately with typec_altmode_get_orientation() if necessary. thanks, -- heikki _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
