hw-cycles always returns 0

[rseac]

Most applications return the hw-cycles output as 0. Examples such as imatmul provide cycle numbers after an execution on a given input, but the hw-cycles ends up still being 0. Is hw-cycle still used? If so, what cycles does it represent.

Hi @rseac, hw-cycles should be first enabled, as done within the benchmarking environment: https://github.com/pulp-platform/ara/blob/main/apps/benchmarks/benchmark/imatmul.bmark#L52

Let me know if there are issues with it, as we updated the VU interface.

This works. Thank you so much.
