Message-ID: <20071007161222.1b758f2f@the-village.bc.nu> Date: Sun, 7 Oct 2007 16:12:22 +0100 From: Alan Cox <alan@...rguk.ukuu.org.uk> To: Valdis.Kletnieks@...edu Cc: Oleg Verych <olecom@...wer.upol.cz>, Ingo Molnar <mingo@...e.hu>, Jan Engelhardt <jengelh@...putergmbh.de>, Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, Dave Jones <davej@...hat.com>, Krzysztof Halasa <khc@...waw.pl>, Medve Emilian-EMMEDVE1 <Emilian.Medve@...escale.com>, Helge Deller <deller@....de> Subject: Re: NAK nettiquete (was Re: "Re: [PATCH 0/2] Colored kernel output (run2)" > The few times I've tried to NAK something outright, I've always tried to attach > plenty of technical explanation Fair comment to my "silly" response The problems I see are - We run on a lot more than VGA PC consoles - We have serial consoles (which may or may not be VT132/ANSI compliant) - The printk paths are run at IRQ time ASAP to get messages to console, that could mean we split existing colour escape code processing and the like. - People redirect the console feed other places via ioctl. Some of them parse "<%d>" as the start But most importantly: - If you want to do "pretty" boot up you do it in X or frame buffer (which is going to get easier and easier with the X shift to kernel side video support) - If you want to do a coloured display after boot then this is a matter for your logging tools As with translation the kernel is the wrong place to do this work. What I would much rather people thought about was - Marker modes for translation (so you know which bits of a message are formatted up) - More consistency on the use of "name: blah" to make it easier to parse - Turning more messages from kernel logs to events when it makes sense (eg "Disk Full", "Media Error", "CPU on fire") So if you want to do a pretty boot, then solve the big picture, the framebuffer initrd graphical boot, the boot display, the combining of artwork and messages in user space from initrd run code. 'leet kernel messages in flashing red are not really the problem that needs solving to do this.
