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 ?
