[Why] State can be cleared without removing individual streams (by calling dc_remove_stream_from_ctx()). This can leave the encoder assignment module in an incoherent state and cause future assignments to be incorrect.

[WHY] If timing and bpp of displays on mst hub are not changed, pbn, slot_num for displays should not be changed. Linux user mode may initiate atomic_check with different display configuration after set mode finished. This will call to amdgpu_dm to re-compute payload, slot_num of displays and saved to dm_connect_state. stream->timing.flags.dsc, pbn, slot_num are updated to values which may be different from that were used for set mode. when dsc hub with 3 4k@60hz dp connected, 3 dsc engines are enabled. timing.flags.dsc = 1. timing.flags.dsc are changed to 0 due to atomic check. when dsc hub is unplugged, amdgpu driver check timing.flags.dsc for last mode set and find out flags.dsc = 0, then does not disable dsc. [HOW] check status of displays on dsc mst hubs. re-compute pbn, slot_num, timing.flags.dsc only if there is mode, connect or enable/disable change. Acked-by:

commit 652de07a ("drm/amd/display: Fully switch to dmub for all dcn21 asics") switched over to using dmub on Renoir to fix Gitlab 1735, but this implied a new dependency on newer firmware which might not be met on older kernel versions. Since sw_init runs before hw_init, there is an opportunity to determine whether or not the firmware version is new to adjust the behavior.

[HOW] Currently the function that finds the corresponding clock for a given voltage only checks for exact voltage level matches.
