drm/amd/display: Set the DML2 attribute to false in all DCNs older than version 3.5

2023-10-26T22:41:22+00:00

When DML2 was introduced, it targeted only new DCN versions. For controlling which ASIC should use this new version of DML, it was introduced the using_dml2 attribute. To avoid ambiguities, this commit explicitly sets using_dml2 to false in all ASICs that do not support DML2.

drm/amd/display: set stream gamut remap matrix to MPC for DCN3+

2023-09-26T21:00:22+00:00

dc->caps.color.mpc.gamut_remap says there is a post-blending color block for gamut remap matrix for DCN3 HW family and newer versions. However, those drivers still follow DCN10 programming that remap stream gamut_remap_matrix to DPP (pre-blending). To enable pre-blending and post-blending gamut_remap matrix supports at the same time, set stream gamut_remap to MPC and plane gamut_remap to DPP for DCN families that support both. It was tested using IGT KMS color tests for DRM CRTC CTM property and it preserves test results.

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

2023-09-26T21:00:21+00:00

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.
