bb-matrix: initial scripts to record TIME(1) metrics for BB and PM combinations 2011-07-12T14:06:04+00:00 Darren Hart dvhart@linux.intel.com 2011-07-09T02:02:12+00:00 50fdf562ce5c41782ff1bdea43a20e769e61eb92 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.
