Not a problem for new > core i7, but probably big deal for athlon 64. do you have facts not speculation for this? Does the athlon 64 really keep its voltage high during idle? That would surprise me greatly... (and if it does, does it matter? the clock is stopped anyway there) the only place where my patch makes a real difference is when the cpu is idle due to blocking IO! So do you have data that the athlon 64 gets too hot if you select a high frequency during an idle period, where the clock is already stopped? -- Arjan van de Ven Intel Open Source Technology Centre For development, discussion and tips for power savings, visit http://www.lesswatts.org -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
