2025-03-05drm/amd/display: fix type mismatch in CalculateDynamicMetadataParameters()Vitaliy Shevtsov1-6/+6
There is a type mismatch between what CalculateDynamicMetadataParameters() takes and what is passed to it. Currently this function accepts several args as signed long but it's called with unsigned integers and integer. On some systems where long is 32 bits and one of these unsigned int params is greater than INT_MAX it may cause passing input params as negative values. Fix this by changing these argument types from long to unsigned int and to int respectively. Also this will align the function's definition with similar functions in other dcn* drivers.

2025-02-25drm/amd/display: stop DML2 from removing pipes based on planesMike Katsnelson1-26/+0
[Why] Transitioning from low to high resolutions at high refresh rates caused grey corruption. During the transition state, there is a period where plane size is based on low resultion state and ODM slices are based on high resoultion state, causing the entire plane to be contained in one ODM slice. DML2 would turn off the pipe for the ODM slice with no plane, causing an underflow since the pixel rate for the higher resolution cannot be supported on one pipe. This change stops DML2 from turning off pipes that are mapped to an ODM slice with no plane. This is possible to do without negative consequences because pipes can now take the minimum viewport and draw with zero recout size, removing the need to have the pipe turned off. [How] In map_pipes_from_plane(), remove "check" that skips ODM slices that are not covered by the plane. This prevents the pipes for those ODM slices from being freed.

2025-02-25drm/amd/display: Update FIXED_VS Link Rate Toggle Workaround UsageMichael Strauss3-3/+20
[WHY] Previously the 128b/132b LTTPR support DPCD field was used to decide if FIXED_VS training sequence required a rate toggle before initiating LT. When running DP2.1 4.9.x.x compliance tests, emulated LTTPRs can report no-128b/132b support which is then forwarded by the FIXED_VS retimer. As a result this test exposes the rate toggle again, erroneously causing failures as certain compliance sinks don't expect this behaviour. [HOW] Add new DPCD register defines/reads to read LTTPR IEEE OUI and device ID. Decide whether to perform the rate toggle based on the LTTPR's IEEE OUI which guarantees that we only perform the toggle on affected retimers.

2025-02-25drm/amd/display: ACPI Re-timer ProgrammingRafal Ostrowski4-0/+82
[Why] We must implement an ACPI re-timer programming interface and notify ACPI driver whenever a PHY transition is about to take place. Because some trace lengths on certain platforms are very long, then a re-timer may need to be programmed whenever a PHY transition takes place. The implementation of this re-timer programming interface will notify ACPI driver that PHY transition is taking place and it will trigger the re-timer as needed. First we need to gather retimer information from ACPI interface. Then, in the PRE case, the re-timer interface needs to be called before we call transmitter ENABLE. In the POST case, it has to be called after we call transmitter DISABLE. [How] Implemented ACPI retimer programming interface.

2025-02-19drm/amd/display: Rename panic functionRodrigo Siqueira2-4/+4
Rename dc_plane_force_update_for_panic to dc_plane_force_dcc_and_tiling_disable to describe the function operation in the name. Also, this function might be used in other contexts, and a more generic name can be helpful for this purpose.

2025-02-19drm/amd/display: Add DCC/Tiling reset helper for DCN and DCERodrigo Siqueira4-0/+66
This commit introduces a function helper for resetting DCN/DCE DCC and tiling. Those functions are generic for their respective DCN/DCE, so they were added to the oldest version of each architecture.

2025-02-19drm/amd/display: Exit idle optimizations before accessing PHYOvidiu Bunea1-0/+5
[why & how] By default, DCN HW is in idle optimized state which does not allow access to PHY registers. If BIOS powers up the DCN, it is fine because they will power up everything. Only exit idle optimized state when not taking control from VBIOS.
