[PATCH 01/11] drm/amd/display: reset lane settings after each PHY repeater LT

[Jasdeep Dhillon]

From: Sung Joon Kim <sungkim@amd.com>

[why]
In LTTPR non-transparent mode, we need
to reset the cached lane settings before performing
link training on the next PHY repeater. Otherwise,
the cached lane settings will be used for the next
clock recovery e.g. VS = MAX (3) which should not be
the case according to the DP specs. We expect to use
minimum lane settings on each clock recovery sequence.

[how]
Reset DPCD and HW lane settings on each repeater LT.
Set training pattern to 0 for the repeater that failed LT
at the proper place.

[PATCH 02/11] drm/amd/display: Fix for dmub outbox notification enable

[Jasdeep Dhillon]

From: Meenakshikumar Somasundaram <meenakshikumar.somasundaram@amd.com>

[Why]
Currently driver enables dmub outbox notification before oubox ISR is
registered. During boot scenario, sometimes dmub issues hpd outbox
message before driver registers ISR and those messages are missed.

[How]
Enable dmub outbox notification after outbox ISR is registered. Also,
restructured outbox enable code to call from dm layer and renamed APIs.

[PATCH 03/11] drm/amd/display: dsc mst re-compute pbn for changes on hub

[Jasdeep Dhillon]

From: Hersen Wu <hersenwu@amd.com>

[why]
when unplug 1 dp from dsc mst hub, atomic_check new request
dc_state only include info for the unplug dp. this will not
trigger re-compute pbn for displays still connected to hub.

[how] all displays connected to dsc hub are available in
dc->current_state, by comparing dc->current_state and new
request from atomic_chceck, it will provide info of
displays connected to hub and do pbn re-compute.

[PATCH 04/11] drm/amd/display: make sure pipe power gating reach requested hw state

[Jasdeep Dhillon]

From: Charlene Liu <Charlene.Liu@amd.com>

[why]
display mapping change will involved pipe power gating on and off.
when doing this too fase, sometimes usbc will have no display.
check HW status, it is still in pipe power gating.

[how]
insert polling HW status to make sure the required state reached.
also add dal registry key handling.

[PATCH 06/11] drm/amd/display: Add affected crtcs to atomic state for dsc mst unplug

[Jasdeep Dhillon]

From: Roman Li <Roman.Li@amd.com>

[Why]
When display topology changed on DSC hub we add all crtcs with dsc support to
atomic state.
Refer to patch:"drm/amd/display: Trigger modesets on MST DSC connectors"
However the original implementation may skip crtc if the topology change
caused by unplug.
That potentially could lead to no-lightup or corruption on DSC hub after
unplug event on one of the connectors.

[How]
Update add_affected_mst_dsc_crtcs() to use old connector state
if new connector state has no crtc (undergoes modeset due to unplug)

Fixes: ("drm/amd/display: Trigger modesets on MST DSC connectors")

[why]
payload and slot number of display on dsc mst hub will be
adjusted when there is change on any display on dsc hub.
to monitor dsc enable/disable, pbn change, we need add log.

[How]
add mst_pbn to dc_dsc_config of dc_crtc_timing.
add dsc, pbn, display name within dc_core_enable_stream,
dc_core_disable_stream, dc_stream_log

[PATCH 10/11] drm/amd/display: Add dsc pre-validation in atomic check

[Jasdeep Dhillon]

From: Roman Li <Roman.Li@amd.com>

[Why]
The previous change:
"Add affected crtcs to atomic state for dsc mst unplug"
forces modeset on all added crctc regardless whether timing changed or not.
Per our implementation of dsc we need modeset only if timing changed.
Otherwise dsc can be programmed incorrectly leading to dsc engine hang.

[How]
During atomic_check pre-compute dsc params.
Only set mode_changed if timing is changed.

RE: [PATCH 00/11] DC Patches Feburary 14, 2022

[Wheeler, Daniel]

[AMD Official Use Only]

Hi all,
 
This week this patchset was tested on the following systems:
 
Lenovo Thinkpad T14s Gen2 with AMD Ryzen 5 5650U, with the following display types: eDP 1080p 60hz, 4k 60hz  (via USB-C to DP/HDMI), 1440p 144hz (via USB-C to DP/HDMI), 1680*1050 60hz (via USB-C to DP and then DP to DVI/VGA)
 
Sapphire Pulse RX5700XT with the following display types:
4k 60hz  (via DP/HDMI), 1440p 144hz (via DP/HDMI), 1680*1050 60hz (via DP to DVI/VGA)
 
Reference AMD RX6800 with the following display types:
4k 60hz  (via DP/HDMI and USB-C to DP/HDMI), 1440p 144hz (via USB-C to DP/HDMI and USB-C to DP/HDMI), 1680*1050 60hz (via DP to DVI/VGA)
 
Included testing using a Startech DP 1.4 MST hub at 2x 4k 60hz, and 3x 1080p 60hz on all systems. Also tested DSC via USB-C to DP DSC Hub with 3x 4k 60hz on Ryzen 9 5900h and Ryzen 5 4500u.
 
Tested on Ubuntu 20.04.3 with Kernel Version 5.13
