And heavily reduced accuracy on a lot of laptops where 1000Hz is enough to make the clock slide every time the battery state is queried or an SMM event triggers. Getting the best of both worlds depends on the stuff discussed at OLS being finished, then you can have 1Khz accurancy and battery life - 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/
