[PATCH 0/9] introduce calibration and simplify grammar

by Pi-Cheng Chen

Hi Juri, This series mainly intends to introduce calibration mechanism and simplify the grammar used in JSON files. [4, 5, 6] of this series are exceptions but also put in this series since the following grammar simplification patches are highly dependent on those features and removal of command line interface done in [4, 5, 6]. This series are also found in: ssh://git@git.linaro.org/people/picheng.chen/rt-app.git calibration_grammar_series Vincent Guittot (9): make load frequency independent fix calibration issue on mt8173 describe resource names in plain string add run and sleep resource types add phase feature remove support of command line interface simplify grammar of JSON files make global object optional make resource object optional README.in | 79 +------- src/rt-app.c | 451 +++++++++++++++++++++++++----------------- src/rt-app_args.c | 328 +------------------------------ src/rt-app_args.h | 3 - src/rt-app_parse_config.c | 492 +++++++++++++++++++++++++++------------------- src/rt-app_types.h | 63 +++--- src/rt-app_utils.c | 64 +++++- src/rt-app_utils.h | 3 + 8 files changed, 666 insertions(+), 817 deletions(-) -- 1.9.1

[PATCH] rt-app: update cpufreq governor efficiency

update cpufreq governor efficiency bench to : - use timer instead of sleep to have a better load emulation - track overrun : run duration exceeds period Signed-off-by: Vincent Guittot <vincent.guittot(a)linaro.org> --- doc/examples/cpufreq_governor_efficiency/dvfs.json | 18 ++++++++++-------- doc/examples/cpufreq_governor_efficiency/dvfs.sh | 20 +++++++++++++++----- doc/examples/cpufreq_governor_efficiency/test.sh | 22 +++++++++++----------- 3 files changed, 36 insertions(+), 24 deletions(-) diff --git a/doc/examples/cpufreq_governor_efficiency/dvfs.json b/doc/examples/cpufreq_governor_efficiency/dvfs.json index c8447df..c1eefe4 100755 --- a/doc/examples/cpufreq_governor_efficiency/dvfs.json +++ b/doc/examples/cpufreq_governor_efficiency/dvfs.json @@ -2,26 +2,28 @@ "tasks" : { "thread" : { "instance" : 1, - "cpus" : [0], -"loop" : 21, + "policy" : "SCHED_FIFO", + "cpus" : [1], + "loop" : 10, "phases" : { - "running" : { - "loop" : 1, - "run" : 100, - }, "sleeping" : { "loop" : 1, - "sleep" : 100, + "timer" : { "ref" : "tick", "period" : 1200000, } + }, + "running" : { + "loop" : 1, + "run" : 900000, } } } }, "global" : { "default_policy" : "SCHED_OTHER", - "calibration" : 90, + "calibration" : 128, "lock_pages" : true, "ftrace" : false, "logdir" : "./", + "log_size" : 2, } } diff --git a/doc/examples/cpufreq_governor_efficiency/dvfs.sh b/doc/examples/cpufreq_governor_efficiency/dvfs.sh index 00ce81d..7caee7d 100755 --- a/doc/examples/cpufreq_governor_efficiency/dvfs.sh +++ b/doc/examples/cpufreq_governor_efficiency/dvfs.sh @@ -6,33 +6,43 @@ set -e echo $1 > /sys/devices/system/cpu/cpu$2/cpufreq/scaling_governor #echo $1 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor sed 's/"cpus" : \[.*\],/"cpus" : \['$2'\],/' -i dvfs.json -sleep 3 if [ $3 ] ; then sed 's/"run" : .*,/"run" : '$3',/' -i dvfs.json fi if [ $4 ] ; then - sed 's/"sleep" : .*,/"sleep" : '$4',/' -i dvfs.json + sed 's/"period" : .*,/"period" : '$4',/' -i dvfs.json fi if [ $5 ] ; then sed 's/^"loop" : .*,/"loop" : '$5',/' -i dvfs.json fi +sync + +sleep 1 + rt-app dvfs.json 2> /dev/null if [ $1 ] ; then + mv -f rt-app-thread-0.log rt-app_$1_run$3us_sleep$4us.log sum=0 loop=0 - for i in $(cat rt-app_$1_run$3us_sleep$4us.log | sed 'n;d' | sed '1d' |cut -f 3); do + overrun=0 + for i in $(cat rt-app_$1_run$3us_sleep$4us.log | sed '1d;n;d' | sed '1d' |cut -f 3); do loop=$(expr $loop + 1) sum=$(expr $sum + $i) + if [ $4 -le $i ] ; then + #echo $i"vs"$4 + overrun=$(expr $overrun + 1) + fi done + sum=$(expr $sum / $loop) - echo $sum - rm -f rt-app_$1_run$3us_sleep$4us.log + echo $sum" "$overrun + #rm -f rt-app_$1_run$3us_sleep$4us.log fi diff --git a/doc/examples/cpufreq_governor_efficiency/test.sh b/doc/examples/cpufreq_governor_efficiency/test.sh index 0160952..4d8cb9c 100755 --- a/doc/examples/cpufreq_governor_efficiency/test.sh +++ b/doc/examples/cpufreq_governor_efficiency/test.sh @@ -40,16 +40,16 @@ test_efficiency() { # Get target gov data first dvfs.sh $1 $2 $3 $4 $5 > $FILENAME - target=$(cat $FILENAME |sed -n '1p') - - # Get powersave data - dvfs.sh powersave $2 $3 $4 $5 > $FILENAME - powersave=$(cat $FILENAME |sed -n '1p') - + target=$(cat $FILENAME |sed -n '$p' | cut -d " " -f 1) + over_target=$(cat $FILENAME |sed -n '$p' | cut -d " " -f 2) # Get performance data dvfs.sh performance $2 $3 $4 $5 > $FILENAME - performance=$(cat $FILENAME |sed -n '1p') - + performance=$(cat $FILENAME |sed -n '$p' | cut -d " " -f 1) + over_perf=$(cat $FILENAME |sed -n '$p' | cut -d " " -f 2) + # Get powersave data + dvfs.sh powersave $2 $3 $4 $5 > $FILENAME + powersave=$(cat $FILENAME |sed -n '$p' | cut -d " " -f 1) + over_save=$(cat $FILENAME |sed -n '$p' | cut -d " " -f 2) if [ $performance -ge $powersave ] ; then echo "powersave: $powersave" echo "performance: $performance" @@ -57,8 +57,8 @@ test_efficiency() { exit fi - echo "\"powersave\" efficiency: 0%" - echo "\"performance\" efficiency: 100%" + echo "\"powersave\" efficiency: 0% overrun: "$over_save + echo "\"performance\" efficiency: 100% overrun: "$over_perf denominator=$(expr $powersave - $performance) @@ -73,7 +73,7 @@ test_efficiency() { fi fi - echo "\"$gov_target\" efficiency: $target%" + echo "\"$gov_target\" efficiency: $target% overrun: "$over_target rm -f $FILENAME } -- 1.9.1
