[PATCH v4] drm/msm/dp: make eDP panel as the first connected connector

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Some userspace presumes that the first connected connector is the main
display, where it's supposed to display e.g. the login screen. For
laptops, this should be the main panel.

This patch call drm_helper_move_panel_connectors_to_head() after
drm_bridge_connector_init() to make sure eDP stay at head of
connected connector list. This fixes unexpected corruption happen
at eDP panel if eDP is not placed at head of connected connector
list.

Changes in v2:
-- move drm_helper_move_panel_connectors_to_head() to
		dpu_kms_drm_obj_init()

Changes in v4:
-- move drm_helper_move_panel_connectors_to_head() to msm_drm_init()
