Message-Id: <20100222141550.67fa46f7.const@mimas.ru> Date: Mon, 22 Feb 2010 14:15:50 +0400 From: Constantin Baranov <const@...as.ru> To: linux-kernel@...r.kernel.org Subject: [PATCH] virtio_console: register hvc0 as console Call hvc_instantiate() when probing virtio device. A console should be registered much earlier but we cannot ensure hvc0 existence until PCI and virtio subsystems initialized. After all, console=hvc0 may be useful even with this limitation.
