The Radeon Compute Profiler (RCP) is a performance analysis tool that gathers data from the API run-time and GPU for OpenCL™ and ROCm/HSA applications. This information can be used by developers to discover bottlenecks in the application and to find ways to optimize the application's performance.

Missing basic counters from full list of performance counters #30
I'm running the current version of RCP (5.6) on a Radeon VII. When I ask for the list of available performance counters its incomplete, it only gives derived counts. Basic counts are nowhere to be found although clearly they're needed for the derived counts. However when I ask rocprofiler (also current version), which I understand is what RCP is based on, for a list of metrics they're all there.
rcprof -l
