[PATCH v3] idlestat: Allocate struct cpufreq_pstate dynamically

by pi-cheng.chen

Initialize struct cpufreq_pstates with initial P-state of CPUs and allocate struct cpufreq_pstate dynamically when parsing trace file to solve the issue caused by missing "scaling_avaialable_freqs" attr when using intel_pstate driver. Changes v2 to v3: Initialize struct cpufreq_pstates with initial P-state of all CPUs and beginning timestamp before trace acquisition and close all P-states with ending timestamp hanges v1 to v2: Sort the cpufreq_pstate list when parsing events Signed-off-by: Pi-Cheng Chen <pi-cheng.chen(a)linaro.org> --- idlestat.c | 259 ++++++++++++++++++++++++++++++++++++++++++++----------------- idlestat.h | 7 ++ trace.h | 1 + 3 files changed, 195 insertions(+), 72 deletions(-) diff --git a/idlestat.c b/idlestat.c index da615cb..8230067 100644 --- a/idlestat.c +++ b/idlestat.c @@ -536,6 +536,121 @@ static struct cpuidle_cstates *build_cstate_info(int nrcpus) return cstates;
