Hi all
--
With regards,
Sandeep Kumar Anantapalli,
As far as I know jiffie counter is incremented HZ times/second. And it is used to measure the time lapses in the kernel code.
I m seeing a case where, actualy time spent in some module using giffies is zero, but while seeing UART logs i am seein 2 sec time difference. I dont know how to interpret this. The case which i am seeing, hrtimers are not enabled yet, so only thing i can rely are on jiffies.
My question here is,
Is it possible that the measured time lapse shown is "0"(jiffie count is same before and after), but actually some time is spent?(say some 2 sec)
In another way..can jiffies may freeze for some time?
Please clarify...
With regards,
Sandeep Kumar Anantapalli,
