[PATCH 08/28] drm/amd/display: Extend dc_stream_get_crc to support 2nd crc engine

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Wayne Lin <Wayne.Lin@xxxxxxx>

[Why & How]
Since now we can set multiple crc windows for secure display, add a new input
parameter for dc_stream_get_crc to indicate to fetch crc from which crc
engine.
