It saves off all the console # logs, the buildstats directories, and creates a bb-pm-runtime.dat file which # can be used to postprocess the results with a plotting tool, spreadsheet, etc. # Before running this script, it is recommended that you pre-download all the # necessary sources by performing the BB_CMD once manually. It is also a good # idea to disable cron to avoid runtime variations caused by things like the # locate process. Be sure to sanitize the dat file prior to post-processing as # it may contain error messages or bad runs that should be removed. # # AUTHORS # Darren Hart # # The following ranges are appropriate for a 4 core system with 8 logical units BB_RANGE="04 05 06 07 08 09 10 11 12 13 14 15 16" PM_RANGE="04 05 06 07 08 09 10 11 12 13 14 15 16" DATADIR="bb-matrix-$$" BB_CMD="bitbake core-image-minimal" RUNTIME_LOG="$DATADIR/bb-matrix.dat" # See TIME(1) for a description of the time format parameters # The following all report 0: W K r s t w TIME_STR="%e %S %U %P %c %w %R %F %M %x" # Prepare the DATADIR mkdir $DATADIR if [ $? -ne 0 ]; then echo "Failed to create $DATADIR." exit 1 fi # Add a simple header echo "BB PM $TIME_STR" > $RUNTIME_LOG for BB in $BB_RANGE; do for PM in $PM_RANGE; do RUNDIR="$DATADIR/$BB-$PM-build" mkdir $RUNDIR BB_LOG=$RUNDIR/$BB-$PM-bitbake.log date echo "BB=$BB PM=$PM Logging to $BB_LOG" # Export the variables under test and run the bitbake command export BB_NUMBER_THREADS=$(echo $BB | sed 's/^0*//') export PARALLEL_MAKE="-j $(echo $PM | sed 's/^0*//')" /usr/bin/time -f "$BB $PM $TIME_STR" -a -o $RUNTIME_LOG $BB_CMD &> $BB_LOG echo " $(tail -n1 $RUNTIME_LOG)" echo -n " Cleaning up..." mv tmp/buildstats $RUNDIR/$BB-$PM-buildstats rm -f pseudodone &> /dev/null rm -rf tmp &> /dev/null rm -rf sstate-cache &> /dev/null rm -rf tmp-eglibc &> /dev/null echo "done" done done 541ee48da3bdb5f88508fe871acf38'>main.cpp
