From mboxrd@z Thu Jan 1 00:00:00 1970 From: Hollis Blanchard Subject: [PATCH 0 of 2] implement tty driver for netconsole Date: Thu, 27 Nov 2008 15:11:00 -0600 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Cc: mpm@selenic.com To: netdev@vger.kernel.org Return-path: Received: from fall-lakeland.atl.sa.earthlink.net ([207.69.195.103]:51914 "EHLO fall-lakeland.atl.sa.earthlink.net" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752364AbYK0VWZ (ORCPT ); Thu, 27 Nov 2008 16:22:25 -0500 Sender: netdev-owner@vger.kernel.org List-ID: I have a Kuro Box (a small NAS device running Linux), and it has no serial console (nor any other console for that matter). The most convenient way to get boot output is via the netconsole driver, which is what most Kuro owners do. (The u-boot firmware even supports interactive netconsole allowing us to edit boot configuration.) However, once past kernel boot, userspace currently has no way of outputting data over netconsole. These patches enable that, which is really useful for seeing init script output and debugging ramdisks before they've brought up sshd. -Hollis
