    Poor Timer Resolution on Linux

    mgrochowalski

      I'm trying to run some soft realtime applications on Ubuntu 16.04 (using the low latency kernel) on the Atom x5-z8330 compute stick (STK1AW32SC).

      However checking the timer resolution using "cat /proc/timer_list | grep resolution | uniq" reveals it's limited to 1 millisecond (1000000 nanoseconds) while other Intel processors report accuracy of 1 nanosecond.

       

      Is there some way to fix this?

       

      I feel it may be due to the following failure listed in dmesg:

      "hpet: number irqs doesn't agree with number of timers"
