Subject: [dpdk-dev] [PATCH v3 01/10] event/dsw: add DSW device registration and build system
Date: Tue, 11 Sep 2018 10:02:07 +0200 [thread overview]
Message-ID: <20180911080216.3017-2-mattias.ronnblom@ericsson.com> (raw)
In-Reply-To: <20180911080216.3017-1-mattias.ronnblom@ericsson.com>
This patch contains the Meson and GNU Make build system extensions
required for the Distributed Event Device, and also the initialization
code for the driver itself.
