Hi all, using clock_gettime <http://man7.org/linux/man-pages/man2/clock_gettime.2.html>(CLOCK_MONOTONIC), the problem is solved. Best Regards, Manty On Mon, Dec 1, 2014 at 5:47 PM, manty kuma <mantykuma@gmail.com> wrote:
Hi Vignesh,
Thank you for your answer. I have chosen ktime_get() as it is in sync with the times logged in kernel log. Hence, doing it with ktime_get() will be my first choice.

An alternative that you can consider would be to expose the desired time or value from your driver, using a sysfs entry so that they can be synced to what you are doing in the driver level and user space can read it using 'cat'
Thanks and regards, Vignesh Radhakrishnan

Hi,
I need to measure some timings in my system. At driver level, i am using ktime_get() to log the times. I need to map this to something of the same unit at user space.
I checked /proc/uptime. This value also includes the suspend time which ktime_get() doesn't include. Hence this option is ruled out.
Is there any other proc entry or any other source which is of same unit?
