[Nouveau] [RFC PATCH 6/8] nv50: add support for compute/graphics global performance counters
Samuel Pitoiset

Mon Jun 22 13:53:17 PDT 2015
This commit adds support for both compute and graphics global
performance counters which have been reverse engineered with
CUPTI (Linux) and PerfKit (Windows).
Currently, only one query type can be monitored at the same time because
the Gallium's HUD doesn't fit pretty well. This will be improved later.
