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. :wink:

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)
