#
# profile Profile CPU usage by sampling stack traces at a timed interval.
# For Linux, uses BCC, BPF, perf_events. Embedded C.
#
# This is an efficient profiler, as stack traces are frequency counted in
# kernel context, rather than passing every stack to user space for frequency
# counting there. Only the unique stacks and counts are passed to user space
# at the end of the profile, greatly reducing the kernel<->user transfer.
#
# By default CPU idle stacks are excluded by simply excluding PID 0.
#
# REQUIRES: Linux 4.9+ (BPF_PROG_TYPE_PERF_EVENT support). Under tools/old is
# a version of this tool that may work on Linux 4.6 - 4.8.

# THANKS: Alexei Starovoitov, who added proper BPF profiling support to Linux;
# Sasha Goldshtein, Andrew Birchall, and Evgeny Vereshchagin, who wrote much
# of the code here, borrowed from tracepoint.py and offcputime.py; and
# Teng Qin, who added perf support in bcc.
#
# 15-Jul-2016 Brendan Gregg Created this.
# 20-Oct-2016 " " Switched to use the new 4.9 support.
# 26-Jan-2019 " " Changed to exclude CPU idle by default.
# 11-Apr-2023 Rocky Xing Added option to increase hash storage size.
