perf flamegraph: Use /bin/bash for report and record scriptsAs all the other tools/perf/scripts/python/bin/*-{report,record}scripts, fixing the this problem reported by Daniel Diaz: Our OpenEmbedded builds detected an issue with 5287f9269206 ("perf script: Add flamegraph.py script"): ERROR: perf-1.0-r9 do_package_qa: QA Issue: /usr/libexec/perf-core/scripts/python/bin/flamegraph-report contained in package perf-python requires /usr/bin/sh, but no providers found in RDEPENDS_perf-python? [file-rdeps] This means that there is a new binary pulled in in the shebang line which was unaccounted for: `/usr/bin/sh`. I don't see any other usage of /usr/bin/sh in the kernel tree (does not even exist on my Ubuntu dev machine) but plenty of /bin/sh.

Fri, 20 Mar 2020 16:13:48 +0100

perf script: Add flamegraph.py scriptThis script works in tandem with d3-flame-graph to generate flame graphsfrom perf. It supports two output formats: JSON and HTML (the default).The HTML format will look for a standalone d3-flame-graph template filein /usr/share/d3-flame-graph/d3-flamegraph-base.html and fill in thecollected stacks.Usage: perf record -a -g -F 99 sleep 60 perf script report flamegraphCombined: perf script flamegraph -a -F 99 sleep 60Committer testing:Tested both with "PYTHON=python3" and with the default, that usespython2-devel:Complete set of instructions: $ mkdir /tmp/build/perf $ make PYTHON=python3 -C tools/perf O=/tmp/build/perf install-bin $ export PATH=~/bin:$PATH $ perf record -a -g -F 99 sleep 60 $ perf script report flamegraphNow go and open the generated flamegraph.html file in a browser.At first this required building with PYTHON=python3, but after Ireported this Andreas was kind enough to send a patch making it workwith both python and python3.Signed-off-by: Andreas Gerstmayr Tested-by: Arnaldo Carvalho de Melo Cc: Alexander Shishkin Cc: Jiri Olsa Cc: Mark Rutland Cc: Namhyung Kim Cc: Peter Zijlstra Cc: Brendan Gregg Cc: Martin Spier Link: http://lore.kernel.org/lkml/20200320151355.66302-1-agerstmayr@redhat.comSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux/tools/perf/scripts/python/bin/flamegraph-record
