[Mesa-dev] [PATCH 5/8] draw: implement pipeline statistics in the draw module
Zack Rusin
zackr at vmware.com
Tue Apr 16 20:36:45 PDT 2013
This is a basic implementation of the pipeline statistics in the
draw module. The interface is similar to the stream output statistics
and also requires that the callers explicitly enable it.
Included is the implementation of the interface in llvmpipe and
softpipe. Only softpipe enables the pipeline statistics capability
though because llvmpipe is lacking gathering of the fragment shading
and rasterization statistics.
