The only (very straight forward) problem is that we aren't propagating the freq update to clockevents core and you need to debug a bit there. Also I wanted to see the source of your print message: [ 19.650454] NEW RATE=9250000 [ 19.653644] NEW RATE=9250000 What's this rate ? Old/new ? Because you are atleast printing the old rate here, and the function by default gets the new rate. > I'm wondering if there's another standard clockevent source > I could try (it would be great if it supported high-resolution > timers). I hope you have some platform general-purpose-timers. -- viresh -- 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
