Subject: [PATCH 1/2] xen,input: add xen-kbdfront module parameter for setting resolution
Date: Tue, 21 Mar 2017 18:19:04 +0100	[thread overview]
Message-ID: <20170321171905.31584-2-jgross@suse.com> (raw)
In-Reply-To: <20170321171905.31584-1-jgross@suse.com>

Add a parameter for setting the resolution of xen-kbdfront in order to
be able to cope with a (virtual) frame buffer of arbitrary resolution.
