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.

20# DESCRIPTION
21# This script runs BB_CMD (typically building core-image-sato) for all
22# combincations of BB_RANGE and PM_RANGE values. It saves off all the console
23# logs, the buildstats directories, and creates a bb-pm-runtime.dat file which
24# can be used to postprocess the results with a plotting tool, spreadsheet, etc.
25# Before running this script, it is recommended that you pre-download all the
26# necessary sources by performing the BB_CMD once manually. It is also a good
27# idea to disable cron to avoid runtime variations caused by things like the
28# locate process. Be sure to sanitize the dat file prior to post-processing as
29# it may contain error messages or bad runs that should be removed.
