Abstract
At the most general level, the I/O framework mechanism of the present invention is made up of three interdependent controllers. These controllers are referred to herein as the hardware resource administrator, the information controller, and the device controller. The hardware resource administrator is responsible for organizing information about I/O devices and for making the organized information available to the other controllers. The information controller is responsible for gathering information about I/O devices and for changing and/or updating certain I/O device information. Accordingly, the information controller is made up of individual objects that each represent the characteristics of a particular I/O device. The device controller is responsible for controlling the actual operation of the individual devices, and for performing statistical and diagnostic analysis on the individual I/O devices.
