I'm not opposed to this on principle. Some of the new features like AMD's Core Boost and Intel's Turbo differ in implementation enough to make merging them tricky, but I suspect it's possible. I would definitely prefer to keep the old FID/VID support in powernow-k8.c. I'll run some tests today and see if anything noticeably breaks. -Mark Langsdorf Operating System Research Center AMD -- 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
