2020-01-16drm/amd/display: Flush framebuffer data before passing to DMCUBNicholas Kazlauskas3-42/+24
[Why] There's a data race that can occur between when we update the inbox write pointer vs when the memory for the command actually gets flushed from the map to the framebuffer. DMCUB can read stale or partially invalid data when this race occurs. [How] Before updating the write pointer we can read back all pending commands to ensure that we stall for the writes to be flushed to framebuffer. We don't need to worry about choosing HDP vs VM flush with this mechanism. Drop the dmub_srv_cmd_submit() while we're updating this to work correctly since nothing was actually using this API and the caller should be explicit about the API flow here - by doing this on execute we can give some extra time for the flush to finish while preparing other commands. We should try to avoid writing single commands because of this overhead.

2019-12-19drm/amd/display: Get cache window sizes from DMCUB firmwareNicholas Kazlauskas3-44/+74
[Why] Firmware state and tracebuffer shouldn't be considered stable API between firmware versions. Driver shouldn't be querying anything from firmware state or tracebuffer outside of debugging. Commands are the stable API for this once we have the outbox. [How] Add metadata struct to the end of the data firmware that describes fw_state_size and some reserved area for future use. Drop the tracebuffer and firmware state headers since they can differ per version.

2019-12-19drm/amd/display: Use physical addressing for DMCUB on both dcn20/21Nicholas Kazlauskas4-125/+44
[Why] CW0 and CW1 need to use physical addressing mode for dcn20 and dcn21. The current code for dcn20 is using virtual. [How] We already program the DMCUB like this on dcn21 so we should just use the same sequence for both. Copy the dcn21 sequences into the dmjub_dcn20.c file and rename them.
