GPU Developer Tools

Hello.

I am trying to profile graphic workloads with AMD tools in Lap top. The GPU metrics I am mostly intersted in is L1/L2/L3 cache hit/miss count.

I want to double check that which GPU performance counter is provided in Ryzen 6000 series and its support in GPUPerfAPI and/or Radeon GPU Profiler.

1. GPUPerfAPI document says L1/L2 CacheHit/Miss Count is provided in GCN2 architecutre. Does it still hold for integrated GPU like Radeon 660M in Ryzen 6000 series? 

2. Additionally Radeon GPU Profiler document says "Cache counter data is only available on Radeon RX 5000 series and Radeon RX 6000 series GPUs". So is cache counter data not available in all AMD APU (i.e., integrated graphic cards)? Even in APU with RDNA, RNDA2 architecture (i.e., Ryzen 6000 series) is cache counter data not provided in AMD GPU Profiler?

3. Lastly if there are other APUs which provide L1/L2/L3 cache hit/miss count, it would be really helpful.

Thank you very much.
