Hi all
I am facing problem in running an application over character driver written by me. I wanted to profile that application (time required for each system call) so I compiled it using gcc -pg option. But some time i am receiving SIGPROF signal during ioctl() system call.
Is there any way we can control profile timer's value ? or some other way to get rid of this problem.
hm, how about using TSC? http://en.wikipedia.org/wiki/Time_Stamp_Counter
Thaks for your reply but is there any way we can control profile timer value ?
