"So can you not tracepoints to give EI results for up/down signals and filter out the noise? ", Do you mean I don't need the debugfs at all? For developer, he/she is able to trace anything including the point of Turbo algorithm adjustment(+n/-n). But as a black box, validation will not see the c

RP frequency request is affected by 2 modules: normal turbo algorithm and RPS boost algorithm. By adding RPS boost algorithm to the mix, the final frequency becomes relatively unpredictable. Add a switch to enable/disable RPS boost functionality. When disabled, RP frequency will follow the normal t
