printk's don't usually get peoples attention. Taints and warnings do. If the hardware doesn't allow for nohz-full, and the only way to enable it is via kernel command line, how do you scream to the user that it isn't going to work. We could do a large banner saying: *************************************************************** *************************************************************** *************************************************************** *************************************************************** *** UNSTABLE TSC *** *** NO_HZ_FULL disabled *** *************************************************************** *************************************************************** *************************************************************** *************************************************************** And not do the warning. Maybe that will get peoples attentions? But then again, this could be lost in the boot up if the box prints a lot of data. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
