https://bugzilla.kernel.org/show_bug.cgi?id=75121 --- Comment #11 from Doug Smythies <dsmythies@xxxxxxxxx> --- Created attachment 134821 --> https://bugzilla.kernel.org/attachment.cgi?id=134821&action=edit Perf data for Kernel 3.15RC3-doug2 CPU at 85% load at 200 Hertz load / noload frequency. For this one, I tried the following, which includes C0 but applied to core_pct on a scale from min_perf_pct rather than from 0. However, it made no difference, as the C0 inclusion still dominates. static inline void intel_pstate_calc_busy(struct cpudata *cpu, struct sample *sample) { int32_t core_pct; int32_t c0_pct; int32_t temp; // need to figure out how to do fractional weight #define C0_WEIGHT 1 core_pct = div_fp(int_tofp((sample->aperf)), int_tofp((sample->mperf))); core_pct = mul_fp(core_pct, int_tofp(100)); FP_ROUNDUP(core_pct); c0_pct = div_fp(int_tofp(sample->mperf), int_tofp(sample->tsc)); sample->freq = fp_toint( mul_fp(int_tofp(cpu->pstate.max_pstate * 1000), core_pct)); // sample->core_pct_busy = core_pct; // sample->core_pct_busy = mul_fp(core_pct, c0_pct); temp = core_pct - limits.min_perf_pct; c0_pct = int_tofp(1) - mul_fp((int_tofp(1) - c0_pct), int_tofp(C0_WEIGHT)); temp = mul_fp(temp, c0_pct); sample->core_pct_busy = temp + limits.min_perf_pct; } -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
