https://git.shady.money/linux/atom?h=v6.172024-05-08T18:56:51Zdrm/amd/display: Add Replay capability and state in debugfs2024-05-08T18:56:51ZTom Chungchiahsuan.chung@amd.com2024-04-17T09:29:42Zurn:sha1:504a336a57df8e5c7e136b1a594ffc4a1875dae8
[Why & How]
User can get the panel replay capability and state for debug.
sudo cat /sys/kernel/debug/dri/0/eDP-1/replay_capability
"Sink support: no" - if panel doesn't support Replay
"Sink support: yes" - if panel supports Replay
"Driver support: no\n" - if driver doesn't support Replay
"Driver support: yes\n" - if driver supports Replay
sudo cat /sys/kernel/debug/dri/0/eDP-1/replay_state
It will return current panel replay state

drm/amd/display: Enable Panel Replay for static screen use case2024-01-15T23:35:39ZTom Chungchiahsuan.chung@amd.com2023-12-06T14:07:51Zurn:sha1:5950efe25ee02df4983864b3bc1f460ad5c8d862
[Why]
Enable the Panel Replay if eDP panel and ASIC support.
(prioritize Panel Replay over PSR)
[How]
- Setup the Panel Replay config during the device init
(prioritize Panel Replay over PSR).
- Separate the Replay init function into two functions
amdgpu_dm_link_setup_replay() and amdgpu_dm_set_replay_caps()
to fix the issue in the earlier commit that cause PSR and Replay
enabled at the same time.

We need to make sure that the panel supports replay.
This info is inside the amd vsdb (vendor specific data block). Create a
function to parse the block and read the replay_mode bit.

We need certain conditions for replay to be enabled, so create an
