drm/amd/display: Add prefix for plane functions

2023-10-26T23:00:09Z

This commit adds the amdgpu_dm_plane_ prefix for all functions in the amdgpu_dm_plane.c. This change enables an easy way to filter code paths via ftrace. Reviewed-by: Aurabindo Pillai Acked-by: Roman Li Signed-off-by: Rodrigo Siqueira Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: switch DC over to the new DRM logging macros

2023-09-26T21:00:21Z

For multi-GPU systems it is difficult to tell which GPU a particular message is being printed for and that is undesirable because it complicates debugging efforts. Also, the new macros allow us to enable logging for particular parts of the codebase more selectively (since we no longer need to throw everything at DRM_DEBUG_KMS()). So, for the reasons outlined above we should switch to the new macros. We can accomplish this by using the existing DC_LOGGER code to pass around the relevant `struct drm_device` which will be fed to the new macros in logger_types.h. Also, we must get rid of all instances of the DC_LOG_.*() functions that are currently in amdgpu_dm since we don't use the DC logger there and we can simply refer to the macros directly there instead.

drm/amd/display: enable cursor degamma for DCN3+ DRM legacy gamma

2023-09-06T18:32:10Z

For DRM legacy gamma, AMD display manager applies implicit sRGB degamma using a pre-defined sRGB transfer function. It works fine for DCN2 family where degamma ROM and custom curves go to the same color block. But, on DCN3+, degamma is split into two blocks: degamma ROM for pre-defined TFs and `gamma correction` for user/custom curves and degamma ROM settings doesn't apply to cursor plane. To get DRM legacy gamma working as expected, enable cursor degamma ROM for implict sRGB degamma on HW with this configuration.

Revert "Revert "drm/amd/display: Implement zpos property""

2023-08-30T19:51:17Z

This reverts commit e2066eb4efe0e7d2d329d6e6765ed637a523ac45. The problematic IGT test case (i.e. kms_atomic@plane-immutable-zpos) has been fixed as of commit cb77add45011 ("tests/kms_atomic: remove zpos < N-planes assert") to the IGT repo. So, reintroduce the reverted code.

drm/amd/display: Implement zpos property

2023-07-18T15:08:53Z

Despite certain GPUs supporting multiple overlay planes already in AMDGPU, the driver did not expose the zpos property which is required for userspace to take advantage of multiple overlay planes in any meaningful way. The driver was already hooked up to normalized_zpos, but was just missing the exposure of it.

drm/amd/display: Expose more formats for overlay planes on DCN

2023-07-18T15:08:23Z

DCN planes are universal and therefore overlay planes can use the same formats as primary planes, unlike DCE. Gamescope/Steam Deck would like to take advantage of this functionality for partial composition which in some cases in our pipeline, can contain negative values in some instances.
