drm/amd/display: Fix black screen on video playback with embedded panel

2023-11-29T23:07:49+00:00

[why] We have dynamic power control in driver but should be ignored when power is forced on. [how] Bypass any power control when it's forced on. Cc: stable@vger.kernel.org Reviewed-by: Nicholas Kazlauskas Acked-by: Hamza Mahfooz Signed-off-by: Sung Joon Kim Signed-off-by: Alex Deucher

drm/amd/display: Remove config update

2023-11-29T23:06:44+00:00

[Why] Prevent overwrite of dc->config.use_default_clock_table, as it should be pre-configured. Reviewed-by: Nicholas Kazlauskas Acked-by: Hamza Mahfooz Signed-off-by: Taimur Hassan Signed-off-by: Alex Deucher

drm/amd/display: Add z-state support policy for dcn35

2023-11-29T22:52:00+00:00

[Why] DML2 means that the dcn3x policy for calculating z-state support no longer runs from validate_bandwidth. This means we are unconditionally allowing Z8, the hardware default. [How] Port the policy over to DCN35, but with a few modifications: - Don't use min_dst_y_next_start as a check for Z8/Z10 allow - Add support for overriding the Z10 stutter period per ASIC - Cleanup the code to make the policy assignment more clear Reviewed-by: Charlene Liu Acked-by: Hamza Mahfooz Signed-off-by: Nicholas Kazlauskas Signed-off-by: Alex Deucher

drm/amd/display: Fix encoder disable logic

2023-11-17T05:55:17+00:00

[WHY] DENTIST hangs when OTG is off and encoder is on. We were not disabling the encoder properly when switching from extended mode to external monitor only. [HOW] Disable the encoder using an existing enable/disable fifo helper instead of enc35_stream_encoder_enable.

drm/amd/display: avoid variable reinitialization

2023-11-07T17:03:31+00:00

The member variable enable_hpo_pg_support is already initialized and hence the reinitialization instruction can be removed. Issue identified using the doubleinit.cocci Coccinelle semantic patch script. Signed-off-by: Bragatheswaran Manickavel Signed-off-by: Alex Deucher
