Re: [PATCH] intel_pstate: Avoid pointless FRAC_BITS shifts under div_fp()

I proposed also to simplify the intel_pstate_calc_busy function: core_pct = int_tofp(sample->aperf) * int_tofp(100); core_pct = div64_u64(core_pct, int_tofp(sample->mperf)); is equivalent to: core_pct = sample->aperf * int_tofp(100); core_pct = div64_u64(core_pct, sample->mperf)

Hi, The wmsrl is supposed to write on the MSR corresponding to the cpu that is executing it. However, it seems that the following commit done by Joe Konno already fixed this bug on BYT. 0dd23f94251f49da99a6cbfb22418b2d757d77d6 Now, we need to figure out why the wmsrl is not executed on the
