[Mesa-dev] [PATCH 6/6] st/va: implement vlVa(Query|Create|Get|Put|Destroy)Image

Leo Liu leo.liu at amd.com
Tue Sep 23 09:44:43 PDT 2014


This patch implements functions for images support,
which basically supports copy data between video
surface and user buffers, in this case supports
SW decode, and other video output
