[PATCH 20/25] intel/context: new execbuf interface for contexts

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

 



To support this we extract the common execbuf2 functionality to be
called with, or without contexts.

The context'd execbuf does not support some of the dri1 stuff.
