hi all,
I am porting from 2.4 to 2.6, There is a problem, a user space
code which should be pushed to kernel space(driver module). In the user
program there is a nanosleep() function i need to know the respective
kernel routine for nanosleep.
kernel does not have something like sleep, it just schedules a new
process in that time. But if you are trying to sleep for very very
short intervals, use a spin loop (typically when you want to give
hardware some breathing space while writing to it). If you want to
sleep for extended periods, What you are looking for is a timer.
Generally busy waiting loops have a pause instruction in them so that
in cases where the user is using processors with HyperThreading kind
of support, it does not starve the sibling processor.
