2019-06-22drm/amd/display: update DSC MST DP virtual DPCD peer device enumeration policyWenjing Liu
[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 Kazlauskas
[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.

2019-06-22drm/amd/display: Implement DSC MST fair share algorithmWenjing Liu
[why] The current policy will always enable DSC to 12 bpp regardless of if the current bandwidth is enough for MST displays. This logic is not optimal because user will get lower quality output if DSC compression is enabled. This change to is to implement a DSC MST bandwidth fair share algorithm so we will dynamically decide if DSC is needed and what quality (target bpp) is needed to fairly destribute the MST bandwidth in one MST topology. This will allow user to see the most optimal image quality with the given bandwidth. [how] We will start with lowest bandwidth possible and run a Max-Min fairness algorithm to fairly distribute the available bandwidth. If there is still remaining bandwidth, we will try to fit the timing without DSC compression.
