    摘要: In at least one embodiment described herein, an apparatus is provided that can include means for communicating a latency tolerance value for a device connected to a platform from a software latency register if a software latency tolerance register mode is active. The apparatus may also include means for communicating the latency tolerance value from a hardware latency register if a host controller is active. The latency tolerance value can be sent to a power management controller. More specific examples can include means for communicating a latency tolerance value from the software latency register if the software latency tolerance register mode is not active and the host controller is not active. The apparatus can also include means for mapping a resource space in the software latency register for the device using a BIOS/platform driver. The mapping can be achieved using an advanced configuration and power interface device description.

    摘要: In some embodiments, an apparatus includes processor cores, a smaller non-volatile memory, a larger non-volatile memory to hold an operating system, programs, and data for use by the processor cores. The apparatus also includes volatile memory to act as system memory for the processor cores, and power management logic to control at least some aspects of power management. In response to a power state change command, a system context is stored in the smaller non-volatile memory followed by the volatile memory losing power, and in response to a resume command, the volatile memory receives power and receives at least a portion of the system context from the smaller non-volatile memory. Other embodiments are described.
