Subject: [PATCH 06/13] perf record: Store data mmaps for dwarf unwind
Date: Thu, 7 Jan 2016 10:14:03 +0100 [thread overview]
Message-ID: <1452158050-28061-7-git-send-email-jolsa@kernel.org> (raw)
In-Reply-To: <1452158050-28061-1-git-send-email-jolsa@kernel.org>
Currently we don't synthesize data mmap by default. It depends
on -d option, that enables data address sampling.
But we've seen cases (softice) where DWARF unwinder went through
non executable mmaps, which we need to lookup in MAP__VARIABLE tree.
Making data mmaps to be synthesized for dwarf unwind as well.
