I'd need a kernel function to wait 100 microseconds.
So i want the kernel to do something else for 100uS and then return to my program, is it possible?
any help would be apreciated

Ok, i apparantly have found another way around this problem.
My idea was probably silly anyway

f.68.1 likely to help? But it is not guaranteed.
Better late than never.

IIRC, this question was related to in-driver code. The solution I remember was to read a reg from the PCI device, it always takes a certain amount of time.

A driver can read available system real-time resources easily.
rdtsc for shortest (sub-microsecond) delays, or
northbridge realtime counters (1-100 microseconds)
