[Why] There is a use case that link loss happens accidentally, and we need to recover that link loss as soon as possible. Under this circumstance, we will perform link training, and try to recover the link that's just lost. However, if link PHY is disabled before link training happens, then DP display will never come back again. Also, please note that dropping this disable_phy function call won't break USB-C hotplug functionality. (This line of code was firstly introduced associated with a patch to fix USB-C hotplug issue) [How] Don't disable DP transmitter and its encoder before link training happens, even if link loss is detected.

SDMA edc counter registers were added in gfx edc counters array. When querying gfx error counter in that array, there is no way to differentiate sdma instance number for different asic and then results to NULL pointer access when trying to read sdma register base address for instances greater than 2 on Vega20. In addition, this also results to wrong gfx error counters since it actually added sdma edc counters. Therefore, sdma edc counter registers should be separated from gfx edc counter regsiter array and only get initialized when driver tries to enable sdma ras. Signed-off-by:

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.
