Abstract
A method and apparatus for dynamically tuning a shared resource's bandwidth utilization, which enables system I/O software to control the length of burst accesses of a shared resource by peripheral components coupled to a peripheral component bus. The present mechanism enables the system I/O software to conduct empirical tests of bandwidth utilization by bus masters accessing the shared resource over the peripheral component bus. Based upon the empirical tests, the system I/O software can tune bandwidth utilization to attain a balance between peripheral component bus performance, and host bus performance.
