Subject: [PATCH v2] x86/xen: add tty0 and hvc0 as preferred consoles for dom0
Date:   Tue, 27 Feb 2018 11:19:22 +0100
Message-Id: <20180227101922.15701-1-jgross@suse.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Today the tty0 and hvc0 consoles are added as a preferred consoles for
pv domUs only. As this requires a boot parameter for getting dom0
messages per default, add them for dom0, too.
