# stackcollapse.py - format perf samples with one line per distinct call stack
# SPDX-License-Identifier: GPL-2.0

# This script's output has two space-separated fields.  The first is a semicolon
# separated stack including the program name (from the "comm" field) and the
# function names from the call stack.  The second is a count:
#
#  swapper;start_kernel;rest_init;cpu_idle;default_idle;native_safe_halt 2
#
# The file is sorted according to the first field.
#
# Input may be created and processed using:
#
#  perf record -a -g -F 99 sleep 60
#  perf script report stackcollapse > out.stacks-folded
#
# (perf script record stackcollapse works too).
