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 <dvhart@linux.intel.com> +# + +# The following ranges are appropriate for a 4 core system with 8 logical units +# Use leading 0s to ensure all digits are the same string length, this results +# in nice log file names and columnar dat files. +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" + + echo -n " Preparing the work directory...
