ABSTRACT:
A hardware access layer interface for performing diagnostics in a computer system having an operating system and at least one hardware device. The interface is a registering and synchronizing agent in the given operating system. The interface has a device driver for managing the hardware device, a kernel module for communicating with the device driver and the operating system, and a diagnostic module for coordinating with the kernel module and/or the device driver in order to perform diagnostics on the hardware device. The interface enables the device driver to publish its capabilities to interested diagnostic modules or the module responsible for managing the device.
