Abstract: A mechanism where the locked pages are saved and restored by a hardware accelerator which is transparent to the OS. Prior to standby entry, the OS puts all DMA capable devices in the lowest-powered device low-power state after disabling bus mastering. The OS flushes all pageable memory to an NVM (in segments that are kept in self-refresh) and provides a list of pinned and locked pages in the DRAM to a power management controller (p-unit). The p-unit checks for all Bus Mastering DMA to be turned off and checks if a next OS timer wake event (TNTE) is greater than a threshold, to decide whether to enable or disable PASR or MPSM in Standby. If the conditions are met, the p-unit triggers a hardware accelerator to consolidate the pinned and locked pages in the DRAM to certain segment(s) of the DRAM during standby states, making it transparent to the OS.

Abstract: Particular embodiments described herein can offer a method that includes determining that a first reported latency tolerance associated with at least one first device has not been received, and causing determination of a platform latency tolerance based, at least in part, on a first predefined latency tolerance, which is to serve as a substitute for the first reported latency tolerance.

Abstract: In one embodiment, a method is provided. The method of this embodiment provides selecting one of a plurality of host transmit queues on a host memory by selecting an entry from a queue descriptor list on a network device, the selected entry being associated with one or more packets on the host memory, retrieving at least one of the one or more packets from the host memory, and storing the at least one of the one or more packets in a device transmit queue of the network device.

Abstract: In one embodiment, a method is provided. The method of this embodiment provides Therefore, in one embodiment, a method may include performing real-time MAC (media access control) functions, and at least one non real-time MAC function of a plurality of non real-time MAC functions on a network device of a system on a network; and performing others of the plurality of non real-time MAC functions on a host processor of the system on the network.

Abstract: A mobile station in a wireless network includes a roaming timer. The roaming timer is set based on various criteria, and when the roaming timer expires, an attempt to roam is performed.
