* meta/lib+scripts: Convert to SPDX license headersRichard Purdie2019-05-091-14/+1
| | | | | | | | | | | | | | | | | | | | | | | This adds SPDX license headers in place of the wide assortment of things currently in our script headers. We default to GPL-2.0-only except for the oeqa code where it was clearly submitted and marked as MIT on the most part or some scripts which had the "or later" GPL versioning. The patch also drops other obsolete bits of file headers where they were encoountered such as editor modelines, obsolete maintainer information or the phrase "All rights reserved" which is now obsolete and not required in copyright headers (in this case its actually confusing for licensing as all rights were not reserved). More work is needed for OE-Core but this takes care of the bulk of the scripts and meta/lib directories. The top level LICENSE files are tweaked to match the new structure and the SPDX naming.

* bb-matrix: Clean before, rather than after, buildingPeter Kjellerstedt2013-09-141-7/+5
| | | | | | | | | | | | | This makes sure the the first build starts from a clean state. Otherwise one could have the first build affected by any leftover state from a previous build. This also leaves a working state behind after the final build.

* bb-matrix: Fix min and max calculationsDarren Hart2013-01-211-1/+4
| | | | | | | | | | | | | | | | The BB and PM ranges were originally intended to use leading 0s to ensure all the values were the same string length, making for nice log filenames and columnar dat files. However, not everyone will do this - especially if it isn't documented. Document the intent. Make the generation and parsing of dat files robust to either method.

* bb-matrix: correct BB and PM number canonicalizationDarren Hart2011-07-141-2/+2
| | | | | | | | | | | The bash string operation ${BB##*0} was greedy and in addition to converting "02" to "2", also converted "20" to "", causing all builds for a BB value ending in 0 to run with BB_NUMBER_THREADS=1.

* bb-matrix: initial scripts to record TIME(1) metrics for BB and PM combinationsDarren Hart2011-07-121-0/+78
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.
