drm/amd/display: Check if PSR enabled when entering MALL

2022-11-23T14:47:14+00:00

[Description] - When attempting to enter MALL SS when a PSR panel is connected, we have to check that the PSR panel has already entered PSR because the vsync interrupt call is per display index (can be called for the non-PSR panel first) - Also don't override link settings when programming phantom stream (main and phantom pipe share the same link) Reviewed-by: Jun Lei Acked-by: Brian Chang Signed-off-by: Alvin Lee Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: refactor enable/disable audio stream hw sequence

2022-10-24T18:35:27+00:00

[why] 1. As recommended by hardware team, don't enable APG when stream is not enabled. 2. Move audio stream encoder programming into link_hwss. [how] 1. Merge dp_audio_enable into enable audio stream hw sequence. 2. Move stream encoder programming into link hwss level to unify stream encoder programming interface.

[Why] There is a coding error when moving dp disable link phy to hw sequencer, where the receiver power control is missed during this refactor. [how] 1. Add back missing receiver power control in disable link phy. 2. minor modifications to ensure there is no undesired sequence changes in dp link enable/disable.

drm/amd/display: rework recent update PHY state commit

2022-09-19T19:10:24+00:00

[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.

drm/amd/display: Fix primary EDP link detection

2022-08-29T21:59:17+00:00

[HOW&WHY] EDP link detection must be updated to support a primary EDP with a link index of greater than 0. * SWDEV-342936 - dc: DSC bringup for SAG 1.5 [WHY] SmartAccess Graphics 1.5 (a.k.a SmartMux 1.5) requires seamless switching between GPUs with DSC enabled. [HOW] Moved DSC programming to apply_single_control_ctx_to_hw before the stream enablement logic to ensure the CRC checker provides valid values for non-black frames allowing the system to come out of forced PSR on d2i. Added additional logic to both generate a black frame through setVisibility calls and keep track of the CRCs values for this black frame when coming out of forced PSR. Updating logic for DalRegKey_DisableDSC to disable DSC on EDP and all ports for systems. [CLEANED] dc: Moved DSC programming to before stream enablement [HOW&WHY] Moved DSC programming to apply_single_control_ctx_to_hw before the stream enablement logic.
