Subject: [PATCH v3 2/2] eal: warn user that VFIO is disabled
Date: Mon, 30 Oct 2017 17:36:53 +0100	[thread overview]
Message-ID: <6d3b81d98b4d1b3754c616f71b293f2119d79bd1.1509381300.git.gaetan.rivet@6wind.com> (raw)
In-Reply-To: <8492fe4cf1a8d6f15d389c9148e4942f1d060a40.1509381300.git.gaetan.rivet@6wind.com>

If VFIO is not compatible with the kernel used, print a soft warning to
the user if RTE_EAL_VFIO was still enabled in the configuration.
