drm/amd/display: Retain phantom pipes when min transition into subvp (#7358)

2022-11-29T16:03:38+00:00

[Description] - When entering into a SubVP config that requires a minimal transition we need to retain phantom pipes and also restore the mall config - This is because the min transition will remove phantom pipes from the context (shallow copy) and not restore it's original state - This is just a workaround, and needs a proper fix Reviewed-by: Jun Lei Acked-by: Jasdeep Dhillon Signed-off-by: Alvin Lee Signed-off-by: Alex Deucher

drm/amd/display: Add margin on DRR vblank start for subvp

2022-11-23T14:47:13+00:00

[Description] - Add margin for HUBP "jitter" for SubVp + DRR case - Also do a min transition even if MPO is added on a non SubVP pipe (i.e. added on DRR pipe for SubVP + DRR) 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: Drop struct crc_region and reuse struct rect

2022-10-27T18:42:40+00:00

[Why] reuse struct rect rather than adding a new struct. [How] - Userspace keeps inputting x_start, y_start, x_end, y_end - We translate data to x, y, width, height in code flow to store - translate back to x_start, y_start, x_end, y_end before programming HW Tested-by: Mark Broadworth Reviewed-by: Wayne Lin Acked-by: Rodrigo Siqueira Signed-off-by: Alan Liu Signed-off-by: Alex Deucher

drm/amd/display: Implement secure display on DCN21

2022-10-27T18:42:32+00:00

[Why] Porting secure display feature from DCN10 to DCN21. Support single display for now and will extend to multiple displays. [How] - use workqueue to offload works for dmub or dmcu firmware - after receiving ROI update from userspace, set skip_frame_cnt to 1 - refactor amdgpu_dm_crtc_handle_crc_window_irq() - disable PSR before activating secure_display on a crtc - check if secure_display is activated before enabling psr - only work for single display for now.

drm/amd/display: Include surface of unaffected streams

2022-10-24T18:34:46+00:00

The commit stream function does not include surfaces of unaffected streams, which may lead to some blank screens during mode change in some edge cases. This commit adds surfaces of unaffected streams followed by kernel-doc for documenting some of the fields that participate in this change. v2: squash in kerneldoc warning fix (Alex) Reviewed-by: Harry Wentland Signed-off-by: Rodrigo Siqueira Co-developed-by: Aurabindo Pillai Signed-off-by: Aurabindo Pillai Signed-off-by: Alex Deucher

drm/amd/display: Remove interface for periodic interrupt 1

2022-09-29T13:41:44+00:00

[why] Only a single VLINE interrupt is available so interface should not expose the second one which is used by DMU firmware. [how] Remove references to periodic_interrupt1 and VLINE1 from DC interfaces.

drm/amd/display: HDMI ODM Combine Policy Correction

2022-08-25T17:34:40+00:00

[WHY] Reprogramming the stream despite no changes in ODM combine mode. Reprogramming the stream would cause intermittent black screen on display which could only be recovered through enable/disable sequence. [HOW] Fixed bug where we detected a change in ODM combine mode despite ODM combine mode being disabled. Also removed code which required stream to be reprogrammed once a change in ODM combine mode was noticed. Lastly we do not support dynamic ODM switching for HDMI TMDS and FRL on DCN32, therefore we never want to change its ODM policy.

drm/amd/display: Indicate stream change on ODM change

2022-07-05T20:14:11+00:00

[Why] With ODM policy 2 to 1, there exists a new use case scenario where stream content is unchanged, but ODM may be used. When this happens, the stream needs to be committed with a new pipe setting. This did not happen due to stream change detection logic not accounting for ODM. [How] Set ODM flag in stream and commit stream when change in ODM has been detected due to policy change.
