[PATCH v2] idlestat: Support energy modeling of idle consumption at different OPPs

by Xunlei Pang

From: Xunlei Pang <pang.xunlei(a)linaro.org> BACKGROUND Overview: Currently idlestat only handles a energy model with a single value for energy savings when going to WFI. IOW, idlestat does not know what OPP (frequency, voltage) is this WFI energy savings calculated at. Add funtionality to allow a table of OPP and energy saving values to be listed so that the savings at various frequencies can be modeled correctly. As an example, a platform may have different power consumption when idled at different OPPs, as follow: @1989 MHz: single core in WFI consumes about 120 mW @1001 MHz: single core in WFI consumes about 45 mW @ 507 MHz: single core in WFI consumes about 30 mW This data is useful to optimise a platform's idle policy. MODIFICATION METHOD Now we want to modify the format of idlestat's energy model to accomodate the different C-states energy data at different OPPs. Let's take a simple example to explicate the way: Assuming different C-States energy data below: 1200Mhz: WFI 80 10 1200Mhz: cluster-sleep-b 30 5 1000Mhz: WFI 70 0 1000Mhz: cluster-sleep-b 25 0 Before modification: clusterA: 2 cap states 2 C states P-states: 1200 15200 6997 1000 8446 3846 C-states: WFI 70 0 cluster-sleep-b 25 0 After modification: clusterA: 2 cap states 2 C states P-state C-states pair 1: 1200 15200 6997 WFI 80 10 cluster-sleep-b 30 5 P-state C-states pair 2: 1000 8446 3846 WFI 70 0 cluster-sleep-b 25 0 In this way, we ensure P-states and C-States always appear in pairs.

[PATCH v2] doc: measure the efficiency of cpufreq governors

by Xunlei Pang

From: Xunlei Pang <pang.xunlei(a)linaro.org> DVFS adds a latency in the execution of task because of the time to decide to move at max freq. We need to measure this latency and check that the governor stays in an acceptable range. When workgen runs a json file, a log file is created for each thread. This log file records the number of loop that has been executed and the duration for executing these loops (per phase). We can use these figures to evaluate to latency that is added by a cpufreq governor and its "performance efficiency". We use the run+sleep pattern to do the measurement, for the run time per loop, the performance governor should run the expected duration as the CPU stays a max freq. At the opposite, the powersave governor will give use the longest duration (as it stays at lowest OPP). Other governor will be somewhere between the 2 previous duration as they will use several OPP and will go back to max frequency after a defined duration which depends on its monitoring period. The formula: duration of powersave gov - duration of the gov -------------------------------------------------------- x 100% duration of powersave gov - duration of performance gov will give the efficiency of the governor. 100% means as efficient as the perf governor and 0% means as efficient as the powersave governor. This patch offers json files and shell scripts to do the measurement, Usage: ./test.sh <cpus> <runtime> <sleeptime> cpus: number of cpus in the CPU0's frequency domain runtime: running time in ms per loop of the workload pattern sleeptime: sleeping time in ms per loop of the workload pattern Example: "./test.sh 4 100 1000" means CPU0~CPU3 sharing frequency, "100ms run + 1000ms sleep" workload pattern. test result on my machine: ~#./test.sh 4 100 1000 Frequency domain CPU0~CPU3, run 100ms, sleep 1000ms: powersave efficiency: 0% performance efficiency: 100% conservative efficiency: 28% ondemand efficiency: 95% NOTE: Make sure there are "sed", "cut", "grep", "rt-app", etc tools on your test machine, and run the script under root privilege.

[RFC PATCH] idlestat: Support energy modeling of idle consumption at different OPPs

by Xunlei Pang

From: Xunlei Pang <pang.xunlei(a)linaro.org> BACKGROUND Overview: Currently idlestat only handles a energy model with a single value for energy savings when going to WFI. IOW, idlestat does not know what OPP (frequency, voltage) is this WFI energy savings calculated at. Add funtionality to allow a table of OPP and energy saving values to be listed so that the savings at various frequencies can be modeled correctly. As an example, a platform may have different power consumption when idled at different OPPs, as follow: @1989 MHz: single core in WFI consumes about 120 mW @1001 MHz: single core in WFI consumes about 45 mW @ 507 MHz: single core in WFI consumes about 30 mW This data is useful to optimise a platform's idle policy. MODIFICATION METHOD Now we want to modify the format of idlestat's energy model to accomodate the different C-states energy data at different OPPs. Let's take a simple example to explicate the way: Assuming different C-States energy data below: 1200Mhz: WFI 80 10 1200Mhz: cluster-sleep-b 30 5 1000Mhz: WFI 70 0 1000Mhz: cluster-sleep-b 25 0 Before modification: clusterA: 2 cap states 2 C states P-states: 1200 15200 6997 1000 8446 3846 C-states: WFI 70 0 cluster-sleep-b 25 0 After modification: clusterA: 2 cap states 2 C states P-state C-states pair 1: 1200 15200 6997 WFI 80 10 cluster-sleep-b 30 5 P-state C-states pair 2: 1000 8446 3846 WFI 70 0 cluster-sleep-b 25 0 In this way, we ensure P-states and C-States always appear in pairs.

[PATCH v3] add regression test function of idlestat

by Zhaoyang Huang

the commit add one Makefile rule which will compare the output of the $(PLAT).trace to $(PLAT).report to check if idlestat have no regression bellowing command line can verify it via the preloaded juno.trace and juno.report make check PLAT=juno --- Makefile | 5 + juno.report | 91 ++++++++++++++ juno.trace | 401 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 497

[PATCH v4] add regression test function of idlestat

by Zhaoyang Huang

the commit add one Makefile rule which will compare the output of the $(PLAT).trace to $(PLAT).report to check if idlestat have no regression bellowing command line can verify it via the preloaded juno.trace and juno.report make check PLAT=juno --- Makefile | 5 + juno.report | 91 ++++++++++++++ juno.trace | 401 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 497

[PATCH] [PATCH] measure the efficiency of cpufreq governors

by Xunlei Pang

From: Xunlei Pang <pang.xunlei(a)linaro.org> DVFS adds a latency in the execution of task because of the time to decide to move at max freq. We need to measure this latency and check that the governor stays in an acceptable range. When workgen runs a json file, a log file is created for each thread. This log file records the number of loop that has been executed and the duration for executing these loops (per phase). We can use these figures to evaluate to latency that is added by a cpufreq governor and its "performance efficiency". We use the run+sleep patten to do the measurement, for the run time per loop, the performance governor should run the expected duration as the CPU stays a max freq. At the opposite, the powersave governor will give use the longest duration (as it stays at lowest OPP). Other governor will be somewhere between the 2 previous duration as they will use several OPP and will go back to max frequency after a defined duration which depends on its monitoring period. The formula: duration of powersave gov - duration of the gov -------------------------------------------------------- x 100% duration of powersave gov - duration of performance gov will give the efficiency of the governor. 100% means as efficient as the perf governor and 0% means as efficient as the powersave governor. This patch offers json files and shell scripts to do the measurement, Usage: ./test.sh <cpus> <runtime> <sleeptime> cpus: number of cpus in the CPU0's frequency domain runtime: running time in ms per loop of the workload pattern sleeptime: sleeping time in ms per loop of the workload patten Example: "./test.sh 4 100 1000" means CPU0~CPU3 sharing frequency, "100ms run + 1000ms sleep" workload pattern. test result on my machine: ~#./test.sh 4 100 1000 Frequency domain CPU0~CPU3, run 100ms, sleep 1000ms: conservative efficiency: 28% ondemand efficiency: 95% NOTE: Make sure there are "sed", "cut", "grep", "rt-app" tools on your test machine, and run the script under root privilege.
