bb-matrix: initial scripts to record TIME(1) metrics for BB and PM combinations
The bb-matrix.sh script will run a bitbake command, building core-image-minimal
by default, for various combinations of BB_NUMBER_THREADS and PARALLEL_MAKE. It
records all relevant metrics of the TIME(1) command for each combination in a
data file.
The bb-matrix-plot.sh script can be used to visualize each of these metrics via
a 3d surface plot, either solid surface or wireframe with a value-map
projection on the XY plane.

+# DESCRIPTION
+# This script operates on the .dat file generated by bb-matrix.sh. It tolerates
+# the header by skipping the first line, but error messages and bad data records
+# need to be removed first. It will generate three views of the plot, and leave
+# an interactive view open for further analysis.

+# DESCRIPTION
+# This script runs BB_CMD (typically building core-image-sato) for all
+# combincations of BB_RANGE and PM_RANGE values. 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.
