[Mesa-dev] [PATCH 23/26] mesa: Track the current vertex/element array buffers for glthread.

Wed Feb 8 18:03:37 UTC 2017
From: Eric Anholt <eric at anholt.net>
We want to support glthread on GLES contexts with reasonable apps, and on
desktop for apps that use VBOs but haven't completely moved to core GL.
To do so, we have to deal with the "the user may or may not pass user
pointers to draw calls" problem.
