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