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?
