https://bugzilla.kernel.org/show_bug.cgi?id=64271 --- Comment #4 from Dirk Brandewie <dirk.brandewie@xxxxxxxxx> --- Here is the patch I will send upstream it may not make it until v3.14-rc1 since the merge window is upon us :-) commit 7d9aba45dbd356686eca097b31028eccec0e11d6 Author: Dirk Brandewie <dirk.j.brandewie@xxxxxxxxx> Date: Mon Oct 14 07:54:45 2013 -0700 cpufreq/intel_pstate: Remove periodic P state boost Remove the periodic P state boost. This code required for some corner case benchmark tests. The calculation of the required P state was incorrect/inaccurate and would not allow P state increase. This was fixed by a combination of commits: 2134ed4 cpufreq / intel_pstate: Change to scale off of max P-state d253d2a intel_pstate: Improve accuracy by not truncating until final result Fixes Bug: https://bugzilla.kernel.org/show_bug.cgi?id=64271 Reported-by: dsmythies@xxxxxxxxx Signed-off-by: Dirk Brandewie <dirk.j.brandewie@xxxxxxxxx> --- drivers/cpufreq/intel_pstate.c | 11 ----------- 1 file changed, 11 deletions(-) diff --git a/drivers/cpufreq/intel_pstate.c b/drivers/cpufreq/intel_pstate.c index 26ab4b8..4d07ae2 100644 --- a/drivers/cpufreq/intel_pstate.c +++ b/drivers/cpufreq/intel_pstate.c @@ -83,8 +83,6 @@ struct cpudata { struct pstate_data pstate; struct _pid pid; - int min_pstate_count; - u64 prev_aperf; u64 prev_mperf; int sample_ptr; @@ -567,15 +565,6 @@ static void intel_pstate_timer_func(unsigned long __data) intel_pstate_sample(cpu); intel_pstate_adjust_busy_pstate(cpu); - - if (cpu->pstate.current_pstate == cpu->pstate.min_pstate) { - cpu->min_pstate_count++; - if (!(cpu->min_pstate_count % 5)) { - intel_pstate_set_pstate(cpu, cpu->pstate.max_pstate); - } - } else - cpu->min_pstate_count = 0; - intel_pstate_set_sample_time(cpu); } -- 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
