how to obtain cache miss rate when run a simple c code, e.g. median in riscv-tests, on any architecture configuration?

[gengtsh]

hi
is there a way to use performance counters described in rocket-chip/src/main/scala/rocket/RocketCore.scala

on specific architecture configuration, i want to measure cache miss rate and some other performance related parameters for input c code, e.g. median in riscv-tests?

I would be grateful if you could tell me how to use it in detail or if you can give me some reference about that.

#1207 repeat, but perhaps more info on PPA measurements should be part of #2960
