drm/amd/display: only warn once in dce110_edp_wait_for_hpd_ready()

2023-02-23T22:35:58+00:00

Since, hot plugging eDP displays isn't supported, it is sufficient for us to warn about the lack of a connected display once. So, use ASSERT() in dce110_edp_wait_for_hpd_ready() instead of DC_LOG_WARNING(). Reviewed-by: Harry Wentland Signed-off-by: Hamza Mahfooz Signed-off-by: Alex Deucher

drm/amd/display: break down dc_link.c

2023-02-08T22:15:51+00:00

[why] dc_link contains over 30k line of code, the decision is to break it down to files residing in link folder based on functionality. This change is the last break down change which will remove dc_link.c file after everything is broken down. [how] Move remaining dc_link.c functions into link_detection, link_dpms, link_validation, link_resource, and link_fpga and remove dc_link.

drm/amd/display: merge dc_link_dp into dc_link

2023-01-24T18:26:25+00:00

[why] Temporarly merge dc_link_dp functions into dc_link for the purpose of removing dc_link_dp files. This is a transitional change for later commits where we will further refactor dc_link file.

drm/amd/display: create accessories, hwss and protocols sub folders in link

2023-01-24T18:26:25+00:00

[why] link component contains three sub folders: accessories - utilities for improving testability, logging or tracing, doesn't impact end user use cases. protocols - specs defined protocols used in end user use cases hwss - hwss owned link_hwss object, served as an abstraction layer in hwss to access various types of encoder/phy/dpia endpoints in a unified interface. sooner we will have files directly under link folder one for the implementation of each major link behavior such as link_create, link_detect, link_validate and link_set_dpms.

drm/amd/display: Skip backlight control delay on external powered links

2023-01-17T20:40:28+00:00

[Why] When an eDP panel is powered externally from a different GPU, we can avoid waiting for hardware sequencing delays when switching the backlight on/off as the display backlight is no longer powered by the original source. [How] This commit extends the 'link_powered_externally' variable to allow bypassing hardware delays for additional backlight commands and force the backlight on/off when a link is powered by another GPU.

drm/amd/display: Optimize link power-down when link powered externally

2023-01-17T20:39:39+00:00

[Why] When an eDP panel is powered externally by a different GPU, we don't need to wait for hardware sequencing delays when powering down a link, as the display is not dependent on the GPU being powered down. [How] This commit adds a variable 'link_powered_externally' to indicate when a link is being powered by another GPU.
