[Mesa-dev] GL_AMD_performance_monitor for Nouveau

[Samuel Pitoiset]

Hi,

As part of my Google Summer of Code 2014, I implemented
GL_AMD_performance_monitor for Nouveau using the state tracker of Gallium.

Currently, only MP counters for NVC0+ (fermi) are exposed through this
extension. At the end of my project, graphics counters for NV50 (tesla) will be
available from GL_AMD_performance_monitor (I'm still working on the kernel
interface).

This set of patches has been tested on NVC1 and NVE7.

Comments and reviews are welcome.

Thanks in advance for your feedbacks!
