[PATCH 09/14] media: medkatek: vcodec: re-construct h264 driver to support svp mode

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

 



Need secure buffer size to convert secure handle to secure
pa in optee-os, re-construct the vsi struct to store each
secure buffer size.

Separate svp and normal wait interrupt condition for svp mode
waiting hardware interrupt in optee-os.
