Abstract

Official abstract text for this publication.

An apparatus is provided that includes a processor, a memory controller coupled to the processor to provide access to a system memory, and an interface controller to communicate with an endpoint device. The interface controller is coupled to the processor and configured to access a register of the endpoint device, the register to be mapped into a memory space of the system, the register to store a service latency tolerance value of the endpoint device. The endpoint device has a service latency tolerance value for a first state and a service latency tolerance value for a second state. The service latency tolerance value for the first state is greater than the service latency tolerance value for the second state.

First claim

Opening claim text (preview).

What is claimed is: 1. A system comprising: a processor; a memory controller coupled to the processor to provide access to a system memory; and an interface controller to communicate with an endpoint device, the interface controller coupled to the processor and configured to access a register of the endpoint device, the register to be mapped into a memory space of the system, the register to store a service latency tolerance value of the endpoint device; wherein the endpoint device has a service latency tolerance value for a first state and a service latency tolerance value for a second state; and wherein the service latency tolerance value for the first state is greater than the service latency tolerance value for the second state. 2. The system of claim 1 , wherein the endpoint device is a peripheral component interconnect express (PCIe) endpoint device. 3. The system of claim 1 , further comprising a communication interface to communicate over a network. 4. The system of claim 1 , further comprising a graphics controller.
