Whenever a connector on an MST network is attached, detached, or undergoes a modeset, the DSC configs for each stream on that topology will be recalculated. This can change their required bandwidth, requiring a full reprogramming, as though a modeset was performed, even if that stream did not change timing. Therefore, whenever a crtc has drm_atomic_crtc_needs_modeset, for each crtc that shares a MST topology with that stream and supports DSC, add that crtc (and all affected connectors and planes) to the atomic state and set mode_changed on its state v2: Do this check only on Navi and before adding connectors and planes on modesetting crtcs v3: Call the drm_dp_mst_add_affected_dsc_crtcs() to update all affected CRTCs Reviewed-by:

If there is limited link bandwidth on a MST network, it must be divided fairly between the streams on that network Implement an algorithm to determine the correct DSC config for each stream The algorithm: This [ ] ( ) represents the range of bandwidths possible for a given stream. The [] area represents the range of DSC configs, and the () represents no DSC. The bandwidth used increases from left to right. First, try disabling DSC on all streams [ ] (|) [ ] (|) Check this against the bandwidth limits of the link and each branch (including each endpoint). If it passes, the job is done Second, try maximum DSC compression on all streams that support DSC [| ] ( ) [| ] ( ) If this does not pass, then enabling this combination of streams is impossible Otherwise, divide the remaining bandwidth evenly amongst the streams [ | ] ( ) [ | ] ( ) If one or more of the streams reach minimum compression, evenly divide the reamining bandwidth amongst the remaining streams [ |] ( ) [ |] ( ) [ | ] ( ) [ | ] ( ) If all streams can reach minimum compression, disable compression greedily [ |] ( ) [ |] ( ) [ ] (|) Perform this algorithm on each full update, on each MST link with at least one DSC stream on it After the configs are computed, call dcn20_add_dsc_to_stream_resource on each stream with DSC enabled.
