Latency Timer Assignment

["Premadhas Mohunraj" <premadhas.mohunraj@wipro.com>]

Hi all,
I would like to know whether any generic standard alogrithm is
available(or to be followed) for assigning Latency Timer
values for a PCI based system. As required it should be
such that no device should be starved of the bus or hog
the bus. 

Thanks & Regards,
