Mali Performance counters for L1

I moved your posting to the Graphics Forum, which will likely find a more appropriate audience.

1. L1 texture cache hits or misses

Not possible to count, and mostly a useless metrics for a GPU (cache misses are expected and in most cases do not actually cause lost cycles).

The "Texture bytes read from L2 per texture cycle" and "Texture bytes read from external memory per texture cycle" counters will give you a feel for the number of bytes fetched per access, but what "good" looks like depends on your texture format.

The "Load/store bytes read from L2 per texture cycle" and "Load/store bytes read from external memory per texture cycle" counters will give you a feel for the number of bytes fetched per access, but what "good" looks like depends on your data structure.

3. Number of requests made to L2 cache

See the shader core memory traffic section in the document you linked - it gives you the L2 traffic breakdown by source.

I have been refering https://developer.arm.com/Processors/Mali-G78 post for architecture specs of g78.

Thank you
