Message-ID: <20071007164452.GA30429@elte.hu> Date: Sun, 7 Oct 2007 18:44:52 +0200 From: Ingo Molnar <mingo@...e.hu> To: Jan Engelhardt <jengelh@...putergmbh.de> Cc: Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, Oleg Verych <olecom@...wer.upol.cz> Subject: Re: [PATCH 1/2] Colored kernel output (run3) Jan, > This patch makes it possible to give kernel messages a selectable > color. It can be chosen at compile time, overridden at boot time, and > changed at run time. here's some (good) text footprint data: with the feature disabled (which is the default), the text size difference with patch #1: vmlinux: text data bss dec hex filename 7732358 1157269 401408 9291035 8dc51b vmlinux.before 7732358 1157269 401408 9291035 8dc51b vmlinux.after i.e. no overhead. Text size difference with patch #2: vmlinux: text data bss dec hex filename 7732358 1157269 401408 9291035 8dc51b vmlinux.before 7732374 1157269 401408 9291051 8dc52b vmlinux.after 16 bytes, or 0.0002% of the total text size. So there's in essence no text overhead to talk about. So the text overhead argument is a red herring.
