摘要
A method and system for choosing an optimal PCI adapter burst length is disclosed. The optimal burst length is automatically determined by the adapter configuration feature of AIX software using a cache-line size of a PCI bridge and the latency timer value of the target PCI adapter as inputs. The method also provides for a user to be able to override the software-calculated setting.
