[Why] Unexpected change of aux hw mapping causes dmub soft hang when initiate aux transation at wrong aux channel. ddc_channel stands for hw dp aux index which is from vbios, but link_index is pure software concept for link count depending on which link is probed first. They are not interchangeable. dmub aux transaction could pass if happens eDP link_index gets the same value as vbios ddc_channel, e.g., ddc_channel = 1, link_index = 1 if they gets different, e.g., ddc_channel = 2, link_index = 0, overwrite ddc_channel with link_index will have wrong ddc channel being used for aux transaction in dmub PSR, cause aux transaction soft hang. [How] ddc_channel mapping to each link is determined by vbios and further parsed in dc.

2022-07-05drm/amd/display: Maintain consistent mode of operation during encoder assignmentJimmy Kizito
[Why] While applying a state to hardware, there is a transition period where the back-end is reset using the old state; then enabled using the new state. Generally, the link encoder configuration module queries stream-to-encoder assignments in either the new or old state based on a mode variable. During the transition there is a need to query both states, however toggling this mode variable can lead to incorrect programming of encoders. [How] - Add new function to explicity query stream-to-encoder assignment in the current state rather than intermittently switch the mode of operation of the link encoder assignment module. - Add additional checks for encoder assignment defects. - Explicitly reset the mode of operation if application of state to hardware ends prematurely.

[HOW?] Add a safe transistion state that minimizes pipe usage before programming new configuration. When adding a plane, the current state has the least pipes required so it is applied without splitting. This must be applied prior to updating the plane_state for seamless transition.

2022-07-05drm/amd/display: Apply ODM 2:1 policy for single display configurationSamson Tam
[Why] Most of the time, a single display uses the ODM combine. When using multi-display, we use ODM combine only if it is necessary. These cases are not flexible enough for us, and we can improve them to take advantage of our hardware. We want to have more control over the ODM policy. [How] This commit add a new debug flag named enable_single_display_2to1_odm_policy to control the ODM policy and another flag named enable_dp_dig_pixel_rate_div_policy to fine control the ODM combine. This is possible by adding a new "pipe.dest" parameter that can be set to ODM 2:1 combined if we use a single display. For dynamic ODM combine, when using DP-DIG, DCN applies K2=2 settings for ODM combine.

2022-06-29drm/amd/display: expose additional modifier for DCN32/321Aurabindo Pillai
[Why&How] Some userspace expect a backwards compatible modifier on DCN32/321. For hardware with num_pipes more than 16, we expose the most efficient modifier first. As a fall back method, we need to expose slightly inefficient modifier AMD_FMT_MOD_TILE_GFX9_64K_R_X after the best option. Also set the number of packers to fixed value as required per hardware documentation. This value is cached during hardware initialization and can be read through the base driver.
