Sorry I was being stupid. I thought you meant the time stamping didn't
have good accuracy, re-reading your post I realise you meant the timer
scheduling.
What is the best way to get the current time for the credit scheduler?
It seems to me that previously netback used something like time
functions in the hypervisitors time.h/c. Where were these functions
placed in the Linux kernel, and are they still there? Is this the best
thing to use, or are there better ways of going about it now? Please
excuse me if these are daft, I'm new to Kernel hacking and Xen.
Thanks
Ross
