drm/amd/display: Add hblank borrowing support

2024-12-02T23:35:32Z

[WHY] Some DSC timing failed at bandwidth validation due to hactive can't be evenly divided on each ODM segment. [HOW] Borrow from hblank to increase hactive to support these timing.

drm/amd/display: Add option to retrieve detile buffer size

2024-12-02T23:35:20Z

[WHY] For better power profiling knowing the detile buffer size at a given point in time would be useful. [HOW] Add interface to retrieve detile buffer from dc state.

drm/amd/display: Enable Request rate limiter during C-State on dcn401

2024-11-20T14:39:42Z

[WHY] When C-State entry is requested, the rate limiter will be disabled which can result in high contention in the DCHUB return path. [HOW] Enable the rate limiter during C-state requests to prevent contention.

drm/amd/display: Prune Invalid Modes For HDMI Output

2024-11-04T16:40:51Z

[Why] 1. HDMI does not have 6 bpc support. Having 6 bpc pass validation does not comply with spec. 2. Validate 420 only for native HDMI, but not apply to pcon use case. 3. Current mode validation log is not readable. [how] 1. Cap 8 bpc for dp-hdmi converter. 2. Validate yuv420 for pcon use case as well, if rgb/yuv444 8bpc cannot fit into pcon bw limitation of the link from the converter to HDMI sink. 3. Add readable pixel_format and color_depth into debug log. Reviewed-by: Wayne Lin Signed-off-by: Fangzhi Zuo Signed-off-by: Zaeem Mohamed Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Implement new backlight_level_params structure

2024-11-04T16:40:43Z

[Why] Implement the new backlight_level_params structure as part of the VBAC framework, the information in this structure is needed to be passed down to the DMCUB to identify the backlight control type, to adjust the backlight of the panel and to perform any required conversions from PWM to nits or vice versa. [How] Modified existing functions to include the new backlight_level_params structure.

drm/amd/display: Add 3DLUT FL HW bug workaround

2024-10-15T15:23:12Z

[Why] There is a known HW bug that causes the internal 3DLUT fetch signal to be lost at VREADY, regardless of whether the OTG lock is being held or not. A workaround is necessary to make sure that this internal signal stays up after OTG unlock. [How] Set the 3DLUT_ENABLE bit immediately before and after the unlock. Also use VUPDATE_KEEPOUT to prevent lock transition in the region between VSTARTUP and VREADY, which could cause issues with this WA sequence. Also including misc. 3DLUT DMA-related sequence fixes to address a few regressions causing corruption.
