Subject: [Qemu-devel] [PATCH 5/6] xen-pt: Hide MSI-X from xen stubdoms
Date: Mon, 11 Mar 2019 14:02:15 -0400	[thread overview]
Message-ID: <20190311180216.18811-6-jandryuk@gmail.com> (raw)
In-Reply-To: <20190311180216.18811-1-jandryuk@gmail.com>

MSI-X is not supported in Xen stubdoms, so it must be disabled.  Use the
existing xen_pt_hide_dev_cap to hide when running under -xen-stubdom.

A compile-time patch was originally written by James McKenzie
