Abstract

An override subsystem on the host side of a serial data link between the host and a peripheral detects and diagnoses link errors by comparing the states of the port's link-layer component and physical layer. An override controller accesses a data-store containing stored policies for responding to particular errors. After selecting the appropriate policy, the override controller takes control of the physical layer, the link-layer component, or both, reconfigures them according to the policy to correct the errors, and returns control of the physical layer to the host controller and link-layer component. As well as error recovery, the override subsystem may be used by applications or drivers to asynchronously manage power consumed by the link.
