* bb-perf: plot histograms base on buildstats dataLeonardo Sandoval2016-11-301-0/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <leonardo.sandoval.gonzalez@linux.intel.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* scripts: Specify the stats to take into accountLeonardo Sandoval2016-11-231-17/+82
| | | | | | | | | | | | | | | | | | | | | | | | | There are many more stats on buildstats that 'Elapsed time', so make the script more flexible to support all stats. Some cmd line examples: $ buildstats.sh -s 'utime' Buildstats' data covers proc's stats in different areas, including CPU times, IO, program system resources and child program system resources. In order to print values on each of these sets from command line, one can use the following: $ buildstats.sh -H -s 'TIME' | less $ buildstats.sh -H -s 'IO' | less and 'RUSAGE' and 'CHILD_RUSAGE' for program and program's child system resources.

* buildstats: Outputs 'task recipe elapsed-time' from each buildstats' recipeLeonardo Sandoval2015-09-121-0/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given a 'buildstats' path (created by bitbake when setting USER_CLASSES ?= "buildstats" on local.conf) and task names, outputs '<task> <recipe> <elapsed time>' for all recipes. Elapsed times are in seconds, and task should be given without the 'do_' prefix. Some useful pipelines 1. Tasks with largest elapsed times $ buildstats.sh -b <buildstats> | sort -k3 -n -r | head do_compile perl-5.20.0-r1 221.82 do_configure gettext-native-0.19.4-r0 140.34 do_compile openssl-native-1.0.2a-r0 107.48 do_compile openssl-1.0.2a-r0 102.10 do_configure perl-native-5.20.0-r0 90.70 do_configure gettext-0.19.4-r0 88.17 do_compile gcc-cross-i586-4.9.2-r0 83.98 do_configure m4-native-1.4.17-r0 83.44 do_compile qemu-native-2.2.0-r1 71.69 do_compile glibc-2.21-r0 60.88 2.

* bb-matrix-plot: Use interpolation for sparse dataPeter Kjellerstedt2013-09-141-1/+1
| | | | | | | | | | | | | | | | If not every combination of BB_NUMBER_THREADS and PARALLEL_MAKE have been tested by bb-matrix.sh, e.g., by using BB_RANGE="04 08 10 12 16" and PM_RANGE="04 08 10 12 16", then the graph that gnuplot generates by default looks very jagged due to the missing data points. By using splines to interpolate the missing data the graph looks a lot better. This should not change graphs where all data points are available in any way, only improve sparse graphs.

* 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 Hart2013-01-212-7/+10
| | | | | | | | | | | | | | | | 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 Hart2011-07-122-0/+215
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.
