A technique for operating an auxiliary processing device is provided. The technique includes based on a first request specifying a handle received from a client, requesting work be performed via a first auxiliary processing device mapped to the handle; responsive to restoration from hibernation, updating a mapping for the handle to refer to a second auxiliary processing device; and based on a second request specifying the handle received from the client, requesting work be performed via the second auxiliary processing device.

Continuity of service for virtualized device after resumption from hibernation

A circuit monitors and resets a co-processor. The circuit includes a hang detector module for detecting a hang in co-processor. The circuit also includes a selective processor reset module for resetting the co-processor without resetting a processor in response to detecting a hang in the co-processor.
