"Ha, ok, I see where you're going with this one." This patch is perfectly suited to reduce heat at home and in the server room, especially during kernel development and debugging, but the average kernel usage already pays off. Just add vt.printk_color=0x08 and all your kernel messages and oopses will be printed using low-power electrons. Extremely useful on SGI Altix 4700, which does print a lot (number of CPU cores), or SunFire X4500 (number of disks). Even if not using one of these systems, CKO can contribute to the lower power usage of PetaBox™ [http://www.archive.org/web/petabox.php]... ;-) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
