Subject: [PATCH 05/13] perf intel-pt: Fix syntax in documentation of config option
Date: Mon, 4 Sep 2017 11:00:36 -0300 [thread overview]
Message-ID: <20170904140044.22912-6-acme@kernel.org> (raw)
In-Reply-To: <20170904140044.22912-1-acme@kernel.org>
From: Jack Henschel <jackdev@mailbox.org>
As specified in tools/perf/Documentation/perf-config.txt, perf
configuration items must be in 'key = value' format, otherwise the
following error message occurs:
$ perf record -e intel_pt//u -- ls
bad config file line 2 in ~/.perfconfig
$ cat .perfconfig
[intel-pt]
mispred-all
Changing to assigning a value to the key 'mispred-all' fixes the issue:
$ perf record -e intel_pt//u -- ls
[ perf record: Woken up 1 times to write data ]
[ perf record: Capured and wrote 0.031 MB perf.data]
$ cat .perfconfig
[intel-pt]
mispred-all = true
