# DESCRIPTION
|
||||
# Given 'buildstats' data (generate by bitbake when setting
|
||||
# USER_CLASSES ?= "buildstats" on local.conf), task names and a stats values
|
||||
# (these are the ones preset on the buildstats files), outputs
|
||||
# '<task> <recipe> <value_1> <value_2> ... <value_n>'. The units are the ones
|
||||
# defined at buildstats, which in turn takes data from /proc/[pid] files
|
||||
#
|
||||
# Some useful pipelines
|
||||
#
|
||||
# 1. Tasks with largest stime (Amount of time that this process has been scheduled
|
||||
# in kernel mode) values
|
||||
# $ buildstats.sh -b <buildstats> -s stime | sort -k3 -n -r | head
|
||||
#
|
||||
# 2. Min, max, sum utime (Amount of time that this process has been scheduled
|
||||
# in user mode) per task (in needs GNU datamash)
|
||||
# $ buildstats.sh -b <buildstats> -s utime | datamash -t' ' -g1 min 3 max 3 sum 3 | sort -k4 -n -r
