drm/amd: append missing includes

2021-12-13T21:32:34Z

This fixes warnings caused by global functions lacking prototypes:, such as: warning: no previous prototype for 'dcn303_hw_sequencer_construct' [-Wmissing-prototypes] 12 | void dcn303_hw_sequencer_construct(struct dc *dc) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ... warning: no previous prototype for ‘amdgpu_has_atpx’ [-Wmissing-prototypes] 76 | bool amdgpu_has_atpx(void) { | ^~~~~~~~~~~~~~~ Reviewed-by: Rodrigo Siqueira Signed-off-by: Isabella Basso Signed-off-by: Alex Deucher

drm/amd/display: Refactor visual confirm

2021-06-08T16:18:37Z

[Why + How] Visual confirm has no asic-specific logic, so we can refactor and unify these functions that are currently spread out across multiple dcn files. Add a new hw sequencer interface update_visual_confirm_color, and a new mpc function pointer set_bg_color. This will allow visual confirm to updated independently of MPCC blending updates. v2: squash in DCN3.1 fixes Signed-off-by: Wyatt Wood Reviewed-by: Aric Cyr Acked-by: Stylon Wang Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

Revert "drm/amd/display: Refactor and add visual confirm for HW Flip Queue"

2021-05-27T16:26:45Z

This reverts commit 3ca402375a2197579d1029e7fa9d856847fe0e7b. Recent visual confirm changes are regressing the driver, causing a black screen on boot in some green sardine configs, or visual confirm is not updated at all.

drm/amd/display: Refactor and add visual confirm for HW Flip Queue

2021-05-20T02:39:36Z

[Why] Visual confirm will indicate if driver is programming the surface address. Refactor is required because much of the visual confirm logic is buried deep in the mpcc files. In addition, visual confirm is not updated during fast updates. [How] In order to have visual confirm for driver flips, visual confirm needs to be updated on every frame, including fast updates. Add a new hw sequencer interface update_visual_confirm_color, and a new mpc function pointer set_bg_color. v2: drop unused variable (Alex) Signed-off-by: Wyatt Wood Reviewed-by: Aric Cyr Acked-by: Stylon Wang Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Add function and debugfs to dump DCC_EN bit

2021-04-09T20:52:03Z

[why] Currently to view the DCC_EN bit the entire DTN log must be dumped. A compact method to view the DCC_EN bit is desirable. [how] Introduce new debugfs interface that only dumps the DCC_EN bit.

drm/amd/display: Old sequence for HUBP blank

2021-02-18T21:43:11Z

New proposed sequence for HUBP blanking causes regressions where the hardware would fail to enter blank which triggers an assert in the new sequence. This change brings back the old sequence.

drm/amd/display: New sequence for HUBP blank

2021-01-14T04:44:22Z

[WHY] DCN30 has a bug where blanking HUBP blocks pstate allow unless HUBP_DISABLE is toggled afterwards. [HOW] Create a HW sequence for blanking HUBP. 1. Wait for enter VBLANK 2. Set HUBP_BLANK 3. Make sure HUBP_IN_BLANK = 1 4. Toggle HUBP_DISABLE on and off to perform soft reset All existing calls to hubp->funcs->set_blank should be replaced with this new sequence. In wait_for_mpcc_disconnect, only blank the pipe being disconnected, and leave all other pipes unmodified.

drm/amd/display: Blank HUBP during pixel data blank for DCN30 v2

2020-11-02T20:31:30Z

[Why] Prior commit "Blank HUBP during pixel data blank for DCN30" missed the call to set_disp_pattern_generator from set_crtc_test_pattern, which re-exposed the issue for which we initially blocked active-only p-state switching. [How] - remove dcn30_blank_pixel_data, set dcn30 back to dcn20 version - new hwss funciton set_disp_pattern_generator - dcn20 version just calls opp_set_disp_pattern_generator - dcn30 version implements the HUBP blank Signed-off-by: Joshua Aberback Reviewed-by: Aric Cyr Acked-by: Qingqing Zhuo Signed-off-by: Alex Deucher
