scripts/buildstats-diff: implement --multi option

2016-10-01T20:45:56+00:00

Makes it possible to average over multiple buildstats. If --multi is specified (and the given path is a directory) the script will read all buildstats from the given directory and use averaged values calculated from them. All of the buildstats must be from a "similar" build, meaning that no differences in package versions or tasks are allowed. Otherwise, the script will exit with an error.

scripts/buildstats-diff: add walltime to --diff-attr

2016-10-01T20:45:56+00:00

For comparing the elapsed wall clock time of tests. Default values for --min-val and --min-absdiff are 5 seconds and 2 seconds. (From OE-Core rev: 8e7a5beb2ce116bcd87111d190a4ac5d771e8884) Signed-off-by: Markus Lehtonen Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

scripts/buildstats-diff: add read_ops and write_ops to --diff-attr

2016-10-01T20:45:56+00:00

Two new options, making it possible to compare the number of filesystem operations of tasks. Defaults for --min-val and --min-absdiff are set to more or less arbitrary 500 and 50 operations, respectively.

scripts/buildstats-diff: add read_bytes and write_bytes to --diff-attr

2016-10-01T20:45:56+00:00

These are I/O counter values from /proc//io and represent the number of bytes read from / written to the storage layer. Default values for --min-val and --min-absdiff limits are set to 512kB and 128kB, respectively.

scripts/buildstats-diff: introduce --diff-attr

2016-10-01T20:45:55+00:00

A new command line option for choosing which "attribute" of the buildstats to compare. At first, the already supported 'cputime' is the only available option. But, refactoring done in this patch should make it easy to add new attribute types.

scripts/buildstats-diff: do not hardcode field widths in output

2016-10-01T20:45:55+00:00

Dynamically adjust the width of all fields in task diff output. Makes it easier to print other units than cputime, too. (From OE-Core rev: 559b858f2a3712ec21debb71681593bd7cf55041) Signed-off-by: Markus Lehtonen Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

scripts/buildstats-diff: implement BSTask class

2016-10-01T20:45:55+00:00

New class representing buildstats data of a single task. (From OE-Core rev: 472818a32f96699a6dc9c7c487f38d716678fd7a) Signed-off-by: Markus Lehtonen Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

scripts/buildstats-diff: rename --min-time and --min-timediff args

2016-10-01T20:45:55+00:00

Rename these arguments to --min-val and --min-absdiff in preparation for supporting other "quantities" than just cputime. (From OE-Core rev: 441336bc1750939c2da2d9e4dc5a6893b283bf68) Signed-off-by: Markus Lehtonen Signed-off-by: Ross Burton Signed-off-by: Richard Purdie
