2023-09-27drm/amd/display: set stream gamut remap matrix to MPC for DCN3+Melissa Wen1-1/+1
dc->caps.color.mpc.gamut_remap says there is a post-blending color block for gamut remap matrix for DCN3 HW family and newer versions. However, those drivers still follow DCN10 programming that remap stream gamut_remap_matrix to DPP (pre-blending). To enable pre-blending and post-blending gamut_remap matrix supports at the same time, set stream gamut_remap to MPC and plane gamut_remap to DPP for DCN families that support both. It was tested using IGT KMS color tests for DRM CRTC CTM property and it preserves test results.

2023-06-09drm/amd/display: Trigger DIO FIFO resync on commit streams for DCN32Saaem Rizvi1-0/+1
[WHY and HOW] Currently, on DCN32 we have an old workaround to resolve a DIO FIFO speed issue when writing to the OTG DIVIDER register. However, this workaround is not safe as we should be applying the DIO FIFO rampup logic when the OTG re disabled along with the encoders. This new workaround accounts for this. If the workaround sequence is incorrect, like it is was, there is a chance we might hang. this new workaround was first implemented in DCN314.

2022-09-29drm/amd/display: Fix various dynamic ODM transitions on DCN32Dillon Varone1-0/+2
[Why&How] Several transitions were fixed that will allow Dynamic ODM and MPO transitions to be supported on DCN32. 1) Due to resource limitations, in certain scenarios that require an MPO plane to be split, the features cannot be combined with the current policy. This is due to unsafe transitions being required (OPP instance per MPCC being switched on active pipe is not supported by DCN), to support the split plane with ODM active as it moves across the viewport. Dynamic ODM will now be disabled when MPO is required. 2) When exiting MPO and re-entering ODM, DC assigns an inactive pipe for the next ODM pipe, which under previous power gating policy would result in programming a gated DSC HW block. New policy dynamically gates/un-gates DSC blocks when Dynamic ODM is active to support transitions on DCN32 only. 3) Entry and exit from 3 plane MPO and Dynamic ODM requires a minimal transition so that all pipes which require their MPCC OPP instance to be changed have a full frame to be disabled before reprogramming. To solve this, the Dynamic ODM policy now utilizes minimal state transitions when entering or exiting 3 plane scenarios. 4) Various fixes to DCN32 pipe merge/split algorithm to support Dynamic ODM and MPO transitions. In summary, this commit fixes various transitions to support ODM->MPO and MPO->ODM.

2022-09-19drm/amd/display: rework recent update PHY state commitWenjing Liu1-1/+4
[why] Original change 594b237b9a07 ("drm/amd/display: Add interface to track PHY state") was implemented by assuming stream's dpms off is equivalent to PHY power off. This assumption doesn't hold in following situations: 1. MST multiple stream scenario, where multiple streams are sharing the same PHY output. Toggle dpms off for one of the stream doesn't power off the PHY due to the presence of other streams. 2. enable stream failure scenario, where enable stream fails due to failure of link training. This will cause DPMS off is set to false, while the actual PHY power state is off in certain cases. Due to the problematic assumption, the logic will skip disabling other streams for MST multiple stream scenario, therefore PHY is not actually powered off. [how] 1. Rework this refactor by moving PHY state update down to hardware level, where we update PHY state in place when hardware sequencer is actually changing the power state of the PHY hardware. 2. Reimplement symclk on TX off workaround in place when we are actually calling transmitter control to power off PHY in dcn32. Note the workaround is added due to the lack of proper software interface to set TX while keeping symclk on. We plan to address this interface problem so we can set TX off only without affecting symclk in future dcn versions.

2022-07-05drm/amd/display: Apply ODM 2:1 policy for single display configurationSamson Tam1-1/+2
[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. Note that this feature affects the following registers: - timing.pix_clk_100khz -> DP_VID_M, DP_VID_N - requested_pix_clk_100hz -> DP_DTOn_PHASE - OTGn_PIXEL_RATE_DIVK2 - DP_PIXEL_PER_CYCLE_PROCESSING_MODE - DIG_FIFO_OUTPUT_PIXEL_MODE - DP_VID_N_MUL Acked-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Signed-off-by: Samson Tam <Samson.Tam@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
