Meaning of performance counters (OpenGL) ?

When I run GL_AMD_performance_monitor functions, it returns almost a hundred of counter groups and more than 7000 counter names.

But their names are pretty user-unfriendly (e.g, CP_000, TCP2_001...), so I can't guess their purpose. I read extension spec and "R6xx/R7xx Register Reference Guide", but they didn't help.

What's the meaning of the performance counters ?

hi,

AMD currently documents a limited set of the performance counters; you can contact devrel in order to get more information.

GPU PerfStudio 2.1 has just been made available and adds support for DX11 and OpenGL 3.0. Please take a look at the Frame Profiler to get a lot of performance information.

I'd also love to see some documentation for some of these counters. For me, just some hints about some of them would suffice.
