drm/amd/display: Add vrr_active_variable to dc_stream_update

2022-06-15T01:38:41Z

[WHY] The display driver on some OSes need to track it in order to perform memory clock switching decisions. [HOW] Propagate the vrr active state to dirty bit so that on mode set it disables dynamic memory clock switching.

drm/amd/display: Firmware assisted MCLK switch and FS

2022-06-15T01:38:41Z

[WHY] Memory clock switching has great potential for power savings. [HOW] The driver code was modified to notify the DMCUB firmware that it should stretch the vertical blank of frames when a memory clock switch is about to start so that no blackouts happen on the screen due to unavailability of the frame buffer. The driver logic to determine when such firmware assisted strategy can be initiated is also implemented and consists on checking prerequisites of the feature.

drm/amd/display: Add flip interval workaround

2022-04-05T14:29:47Z

[WHY] Some games experience low FPS issues when FreeSync is on and VSync is toggled to half refresh rate. [HOW] First create a function to determine workaround conditions, which is when we detect 2 or more VSync interrupts between flips and a very short VSync to flip interval. We do the workaround during VSync interrupts and set the v_total_max and min to nominal. We also cleanup after we exit the game.

drm/amd/display: Update VSC HDR infoPacket on TF change

2022-01-25T23:00:35Z

[why] OnSetSourceContentAttribute it does not trigger an update for the VSC with TF change. [how] In this call, create a new VSC infoPacket based on the new config, and allow DisplayTarget decide if an update and pursuant passive flip is necessary Tested-by: Daniel Wheeler Reviewed-by: Krunoslav Kovac Acked-by: Rodrigo Siqueira Signed-off-by: Reza Amini Signed-off-by: Alex Deucher

drm/amd/display: unhard code link to phy idx mapping in dc link and clean up

2022-01-07T22:21:20Z

[why] 1. Current code hard codes link to PHY mapping in dc link level per asic per revision. This is not scalable. In long term the mapping will be obatined from DMUB and store in dc resource. 2. Depending on DCN revision and endpoint type, the definition of dio_output_idx dio_output_type and phy_idx are not consistent. We need to unify the meaning of these hardware indices across different system configuration. [how] 1. Temporarly move the hardcoded mapping to dc_resource level, which should have full awareness of asic specific configuration and add a TODO comment to move the mapping to DMUB. 2. populate dio_output_idx/phy_idx for all configuration, define usb4_enabled bit instead of dio_output_type as an external enum.

drm/amd/display: Add support for USB4 on C20 PHY for DCN3.1

2021-10-28T18:26:14Z

[Why] Created new fields that matches new B0 structs On DCN31 the mapping of DIO output to PHY differs from A0 to B0 boards with new PHY C20 & this new mapping needed to be handled. [How] Mapped new structure based on new structs Added logic for mapping over A0 and B0 boards Hooked all new structs together.

drm/amd/display: remove unused functions

2021-07-28T20:37:17Z

[why] It has been decided that opm state query support will be dropped. Therefore link encryption enabled and save current encryption states won't be used anymore and there are no foreseeable usages in the future. We will remove these two interfaces for clean up.

drm/amd/display: add update authentication interface

2021-07-28T20:37:17Z

[why] Previously to toggle authentication, we need to remove and add the same display back with modified adjustment. This method will toggle DTM state without actual hardware changes. This is not per design and would cause potential issues in the long run. [how] We are creating a dedicated interface that does the same thing as remove and add back the display without changing DTM state.
