buildstats-plot.sh: Show spaces and underscores correctly in titles/keys

2020-03-29T11:05:31+00:00

Spaces were previously converted to dashes, and underscores caused the next character in the title/key to be printed using subscript due to the enhanced string support in gnuplot.

buildstats*.sh: fix spacing indentation in the files

2020-03-24T16:39:40+00:00

Fix indentation in buildstats.sh and buildstats-plot.sh to convert every line to 4 spaces indentation. (From OE-Core rev: 3971572042ae9bc8226eb92892bb71010287e0a8) Signed-off-by: Luis Martins Signed-off-by: Richard Purdie

buildstats*.sh: add recipe parameter to scripts

2020-03-24T16:39:40+00:00

Add option to filter the stats results for a single recipe, allowing to easilly visuality the task resource consumption per recipe. This is specially useful when debugging the performance of the overall bitbake build system.

buildstats*.sh: add accumulate parameter to scripts

2020-03-24T16:39:40+00:00

Add option to accumulate stats values per recipe, allowing to sum related values such as memory (main process + childs). This is specially useful when debugging the performance of the overall bitbake build system.

buildstats-plot.sh: filter by task

2020-03-24T16:39:40+00:00

Extend buildstats-plot.sh script to also accept the name of the tasks as parameter. This value will be passed directly to buildstats.sh is already provides this option. (From OE-Core rev: 495b6d3d85d2d14d54e324d8da43311a23fdfca6) Signed-off-by: Luis Martins Signed-off-by: Richard Purdie

buildstats-plot.sh: fix invoking buildstats.sh

2020-03-24T16:39:40+00:00

Fix the internal call to buildstats.sh by also providing the buildstats folder location in the system, which might differ from the default location. (From OE-Core rev: 9f4ee2ee8712528ac51ef4ecd17ccde737e8b21d) Signed-off-by: Luis Martins Signed-off-by: Richard Purdie

meta/lib+scripts: Convert to SPDX license headers

2019-05-09T15:31:55+00:00

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-perf: plot histograms base on buildstats data

2016-11-30T15:48:05+00:00

Scripts that produces script data to be consumed by gnuplot. There are two possible plots depending if either the -S parameter is present or not: * without -S: Produces a histogram listing top N recipes/tasks versus stats. The first stat defined in the -s parameter is the one taken into account for ranking * -S: Produces a histogram listing tasks versus stats. In this case, the value of each stat is the sum for that particular stat in all recipes found. Stats values are in descending order defined by the first stat defined on -s EXAMPLES 1. Top recipes' tasks taking into account utime $ buildstats-plot.sh -s utime | gnuplot -p 2. Tasks versus utime:stime $ buildstats-plot.sh -s utime:stime -S | gnuplot -p 3. Tasks versus IO write_bytes:IO read_bytes $ buildstats-plot.sh -s 'IO write_bytes:IO read_bytes' -S | gnuplot -p (From OE-Core rev: 74408c19fba89de54c093fccf65b3a072d6a197b) Signed-off-by: Leonardo Sandoval Signed-off-by: Ross Burton Signed-off-by: Richard Purdie
