[PATCH v2 3/6] [TEST]: rockchip: mpp: support qptable

From: Randy Li
Date: Thu Mar 07 2019 - 05:10:09 EST


I don't care, I don't want to store buffers for a session.
I just want to use it to verify the FFmpeg.

I want the memory region !!!
It can save more time if those data are prepared in userspace.
