drm/amd/display: unhard code link to phy idx mapping in dc link and clean up

2022-01-07T22:21:20+00:00

[why] 1. Current code hard codes link to PHY mapping in dc link level per asic per revision. This is not scalable. In long term the mapping will be obatined from DMUB and store in dc resource. 2. Depending on DCN revision and endpoint type, the definition of dio_output_idx dio_output_type and phy_idx are not consistent. We need to unify the meaning of these hardware indices across different system configuration. [how] 1. Temporarly move the hardcoded mapping to dc_resource level, which should have full awareness of asic specific configuration and add a TODO comment to move the mapping to DMUB. 2. populate dio_output_idx/phy_idx for all configuration, define usb4_enabled bit instead of dio_output_type as an external enum.

drm/amd/display: Fix deadlock when falling back to v2 from v3

2021-10-28T18:26:51+00:00

[Why] A deadlock in the kernel occurs when we fallback from the V3 to V2 add_topology_to_display or remove_topology_to_display because they both try to acquire the dtm_mutex but recursive locking isn't supported on mutex_lock(). [How] Make the mutex_lock/unlock more fine grained and move them up such that they're only required for the psp invocation itself.
