drm/amd/display: Restructure dpia link training

2024-09-18T20:15:07Z

[WHY] We intend to consolidate dp tunneling and conventional dp link training. [HOW] 1. Use the same link training entry for both dp and dpia 2. Move SET_CONFIG of non-transparent mode to dmub side 3. Add set_tps_notification dmub_cmd to notify tps request for non-transparent dpia link training 4. Check dpcd request result and abort link training early if dpia aux tunneling fails 5. Add option to avoid affect old product 6. Separately handle wait_time_microsec for dpia Reviewed-by: Cruise Hung Reviewed-by: George Shen Reviewed-by: Meenakshikumar Somasundaram Signed-off-by: Peichen Huang Signed-off-by: Alex Hung Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Add logs for debugging outbox

2024-07-27T21:35:33Z

drm/amd/display: Add debug option for disabling SLDO optimizations

2024-07-01T20:10:35Z

[Why] DM can hook this up to disable SLDO optimizations in firmware during DMCUB initialization for debug purposes. [How] Add the option and pass it through dmub_srv.

drm/amd/display: Remove register from DCN35 DMCUB diagnostic collection

2024-06-14T20:17:16Z

[Why] These registers should not be read from driver and triggering the security violation when DMCUB work times out and diagnostics are collected blocks Z8 entry. [How] Remove the register read from DCN35. Reviewed-by: Duncan Ma Acked-by: Zaeem Mohamed Signed-off-by: Nicholas Kazlauskas Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Add outbox notification support for HPD redetect

2024-06-14T19:20:20Z

[Why] HPD sense changes can occur during low power states and need to be notified from firmware to driver. Upon notification the hotplug redetection routines should execute. [How] Add Support in DMUB srv and DMUB srv stat for receiving these notifications. DM can hook them up and process the HPD redetection once received.

drm/amd/display: Read default boot options

2024-05-13T19:47:59Z

[WHY] DPIA boot option is set by VBIOS. It gets overwritten when driver loads DMU. [HOW] Read PreOS boot options and determine if dpia is enabled. Reviewed-by: Ovidiu Bunea Acked-by: Alex Hung Signed-off-by: Duncan Ma Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Notify idle link detection through shared state

2024-04-30T13:57:17Z

[Why] We can hang in IPS2 checking DMCUB_SCRATCH0 for link detection state. [How] Replace the HW access with a check on the shared state bit. This will work the same way as the SCRATCH0 but won't require a wake in the case where link detection isn't required.
