drm/amd/display: Fix in secure display context creation

2023-04-24T22:36:46Z

[Why & How] We need to store CRTC information in secure_display_ctx, so postpone the call to amdgpu_dm_crtc_secure_display_create_contexts() until we initialize all CRTCs.

drm/amd/display: Fix when disabling secure_display

2022-12-15T17:18:18Z

[Why] Fix problems when we disable secure_display. [How] - Reset secure display context after disabled - A secure_display_context is dedicate to a crtc, so we set the crtc for it when we create the context.

drm/amd/display: Implement multiple secure display

2022-12-15T17:18:18Z

[Why] Current secure display only work with single display, now make it work with multiple displays. [How] Create secure_display_context for each crtc instance to store its own Region of Interest (ROI) information. v2: squash in warning fix (Alex) Reviewed-by: Wayne Lin Acked-by: Jasdeep Dhillon Signed-off-by: Alan Liu Signed-off-by: Alex Deucher

drm/amd/display: Drop struct crc_region and reuse struct rect

2022-10-27T18:42:40Z

[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

2022-10-27T18:42:32Z

[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: Refactor suspend/resume of Secure display

2021-05-20T02:39:16Z

[Why] Once set ROI and do suspend/resume, current flow will not enable OTG_CRC_CTL again due to we'll defer crc configuration when stream is enabled. [How] Remove current suspend/resume function and have logic implemented into amdgpu_dm_atomic_commit_tail() Signed-off-by: Wayne Lin Reviewed-by: Chao-kai Wang Acked-by: Stylon Wang Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Use PSP TA to read out crc

2021-03-05T20:12:09Z

[Why & How] To read back crc by sending command READ_ROI_CRC to PSP TA to ask it to read out crc of crc window. Signed-off-by: Wayne Lin Reviewed-by: Nicholas Kazlauskas Acked-by: Eryk Brol Acked-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amd/display: Support crc on specific region

2021-03-05T20:11:47Z

[Why] To support feature that calculates CRTC CRC value on specific region (crc window). [How] 1. Use debugfs to specify crtc crc window 2.
