Subject: [PATCH 14/15] perf buildid-list: Add support for mmap2's buildid events
Date: Mon, 14 Dec 2020 11:54:56 +0100 [thread overview]
Message-ID: <20201214105457.543111-15-jolsa@kernel.org> (raw)
In-Reply-To: <20201214105457.543111-1-jolsa@kernel.org>
Add buildid-list support for mmap2's build id data, so we can
display build ids for dso objects for data without the build
id cache update.
$ perf buildid-list
1805c738c8f3ec0f47b7ea09080c28f34d18a82b /usr/lib64/ld-2.31.so
d278249792061c6b74d1693ca59513be1def13f2 /usr/lib64/libc-2.31.so
By default only dso objects with hits are shown.
