Subject: [PATCH v2 5/9] xen/x86: make "earlyprintk=xen" work for HVM/PVH DomU
Date: Thu, 30 Sep 2021 14:18:45 +0200 [thread overview]
Message-ID: <3d212583-700e-8b2d-727a-845ef33ac265@suse.com> (raw)
In-Reply-To: <9a26d4ff-80a1-e0c1-f528-31a8568d41f7@suse.com>
xenboot_write_console() is dealing with these quite fine so I don't see
why xenboot_console_setup() would return -ENOENT in this case.
Adjust documentation accordingly.
