Abstract: Systems, methods, and devices for isolating a misbehaving accelerator circuit, such as an accelerator function unit or an accelerated function context, are provided. An integrated circuit may include a region that includes an accelerator circuit. When the accelerator circuit issues a request, another region of the integrated circuit or a processor connected to the integrated circuit may determine whether there is a misbehavior associated with the request and, in response to determining that there is a misbehavior associated with the request, may perform a misbehavior response to mitigate a negative impact of the misbehavior of the accelerator circuit.

Abstract: An embodiment of a device manager apparatus may include a request processor to process a request for a reconfiguration of a reconfigurable device, a configuration controller communicatively coupled to the request processor to reconfigure the reconfigurable device based on the request, and a pseudo-device manager communicatively coupled to the request processor to create a pseudo device based on the request which corresponds to a functionality of the reconfiguration.

Abstract: A system comprising an accelerator circuit comprising an accelerator function unit to implement a first function, and one or more device feature header (DFH) circuits to provide attributes associated with the accelerator function unit, and a processor to retrieve the attributes of the accelerator function unit by traversing a device feature list (DFL) referencing the one or more DFH circuits, execute, based on the attributes, an application encoding the first function to cause the accelerator function unit to perform the first function.
