2019-06-22drm/amd/display: Rework CRTC color managementNicholas Kazlauskas3-159/+356
[Why] To prepare for the upcoming DRM plane color management properties we need to correct a lot of wrong behavior and assumptions made for CRTC color management. The documentation added by this commit in amdgpu_dm_color explains how the HW color pipeline works and its limitations with the DRM interface. The current implementation does the following wrong: - Implicit sRGB DGM when no CRTC DGM is set - Implicit sRGB RGM when no CRTC RGM is set - No way to specify a non-linear DGM matrix that produces correct output - No way to specify a correct RGM when a linear DGM is used We had workarounds for passing kms_color tests but not all of the behavior we had wrong was covered by these tests (especially when it comes to non-linear DGM). Testing both DGM and RGM at the same time isn't something kms_color tests well either. [How] The specifics for how color management works in AMDGPU and the new behavior can be found by reading the documentation added to amdgpu_dm_color.c from this patch. All of the incorrect cases from the old implementation have been addressed for the atomic interface, but there still a few TODOs for the legacy one. Note: this does cause regressions for kms_color@pipe-a-ctm-* over HDMI. The result looks correct from visual inspection but the CRC no longer matches. For reference, the test was previously doing the following: linear degamma -> CTM -> sRGB regamma -> RGB to YUV (709) -> ... Now the test is doing: linear degamma -> CTM -> linear regamma -> RGB to YUV (709) -> ...

2019-06-22drm/amd/display: update DSC MST DP virtual DPCD peer device enumeration policyWenjing Liu7-261/+161
[why] Current policy assumes virtual DPCD peer device as an individual MST branch device with 1 input and 1 output. However this is only true for virtual DP-to-DP peer device. In general there are three types of virtual DP peer devices. 1. Sink peer device with virtual DPCD. 2. Virtual DP-to-DP Peer device with virtual DPCD. 3. Virtual DP-to-HDMI Protocol Converter Peer Device with Virtual DPCD. So we should break the assumption and handle all three types. [how] DP-to-DP peer device will have virtual DPCD cap upstream. Sink peer device will have virtual DPCD on the logical port. Dp to HDMI protocol converter peer device will have virtual DPCD on its converter port. For DSC capable Synaptics non VGA port we workaround by enumerating a virutal DPCD peer device on its upstream even if it doesn't have one.

2019-06-22drm/amd/display: Copy stream updates onto streamsNicholas Kazlauskas1-0/+97
[Why] Almost every function in DC that works with stream state expects that the current state on the stream is the one that it should be writing out. These functions are typically triggered by specifying a particular stream update - but the actual contents of the stream update itself are ignored, leaving it to the DM to actually update the stream state itself. The problem with doing this in DM is a matter of timing. On Linux most of this is incorrectly done in atomic check, when we actually want it to be done during atomic commit tail while access to DC is locked. To give an example, a commit requesting to modify color management state for DM could come in, be rejected, but still have modified the actual system state for the stream since it's shared memory. The next time color management gets programmed it'll use the rejected color management info - which might not even still be around if it's a custom transfer function. So a reasonable place to perform this is within DC itself and this is the model that's currently in use for surface updates. DC can even compare the current system state to the incoming surface update to determine update level, something that can't currnetly be done with the framework for stream updates. [How] Duplicate the framework used for surface updates for stream updates as well. Copy all the updates after checking the update type.
