The website alsosays "perf report could have a report style [...] that output foldedstacks directly, obviating the need for stackcollapse-perf.pl", so hereit is.This script is a Python rewrite of stackcollapse-perf.pl, using the perfscripting interface to access the perf data directly from Python.Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>Acked-by: Jiri Olsa <jolsa@kernel.org>Cc: Brendan Gregg <bgregg@netflix.com>Link: http://lkml.kernel.org/r/1460467573-22989-1-git-send-email-pbonzini@redhat.comSigned-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> List of files: /linux-6.15/tools/perf/scripts/python/bin/stackcollapse-record Tue, 12 Apr 2016 13:26:13 +0000 Paolo Bonzini <pbonzini@redhat.com>
