Subject: [PATCH 10/15] kernel-shark: Integrate the stream definitions with data model
Date: Tue, 29 Sep 2020 16:41:18 +0300 [thread overview]
Message-ID: <20200929134123.178688-11-y.karadz@gmail.com> (raw)
In-Reply-To: <20200929134123.178688-1-y.karadz@gmail.com>
The visualization model is adapted in order to be able to distinguish
the entries belonging to different Data streams.
We re-enable the visualization model example as well.
