Subject: [PATCH v2 4/9] xen/x86: allow "earlyprintk=xen" to work for PV Dom0
Date: Thu, 30 Sep 2021 14:18:12 +0200 [thread overview]
Message-ID: <d4a34540-a476-df2c-bca6-732d0d58c5f0@suse.com> (raw)
In-Reply-To: <9a26d4ff-80a1-e0c1-f528-31a8568d41f7@suse.com>
With preferred consoles "tty" and "hvc" announced as preferred,
registering "xenboot" early won't result in use of the console: It also
needs to be registered as preferred. Generalize this from being DomU-
only so far.
