Subject: [PATCH 5.10 8/8] perf intel-pt: Fix error timestamp setting on the decoder error path
Date: Mon, 13 Dec 2021 17:45:48 +0200 [thread overview]
Message-ID: <20211213154548.122728-9-adrian.hunter@intel.com> (raw)
In-Reply-To: <20211213154548.122728-1-adrian.hunter@intel.com>
commit 6665b8e4836caa8023cbc7e53733acd234969c8c upstream.
An error timestamp shows the last known timestamp for the queue, but this
is not updated on the error path. Fix by setting it.
Fixes: f4aa081949e7b6 ("perf tools: Add Intel PT decoder")
