摘要： A power management unit (PMU) may determine an optimal power saving state using a break-even period of a power saving state and an expected idle duration based on a first policy. The PMU may determine the optimal power saving state using a first break even period and actual idle duration based on a second policy. The break-even period may equal a minimum time a computer system should remain in a power saving state to compensate for the power consumed by the system to enter and exit that power saving state. The expected idle time duration is determined as an average of idle duration and a recent sample of idle duration. The actual idle duration is the difference of a first and second time point that represents entry and exit points to and from the power saving state. The PMU may transition the system to the optimal power saving state.

摘要： Methods and apparatus for accelerating VM-to-VM Network Traffic using CPU cache. A virtual queue manager (VQM) manages data that is to be kept in VM-VM shared data buffers in CPU cache. The VQM stores a list of VM-VM allow entries identifying data transfers between VMs that may use VM-VM cache “fast-path” forwarding. Packets are sent from VMs to the VQM for forwarding to destination VMs. Indicia in the packets (e.g., in a tag or header) is inspected to determine whether a packet is to be forwarded via a VM-VM cache fast path or be forwarded via a virtual switch. The VQM determines the VM data already in the CPU cache domain while concurrently coordinating with the data to and from the external shared memory, and also ensures data coherency between data kept in cache and that which is kept in shared memory.

摘要： A mobile station in a wireless network provides a presence indication when in a power saving state. The presence indication is sent periodically, and the period is dependent on whether the mobile station is stationary or in motion. The period may also be dependent on an asset protection level of the mobile station.

摘要： Methods and systems may provide for determining a plurality of buffer-related settings for a corresponding plurality of idle states and outputting the plurality of buffer-related settings to a device on a platform. The device may determine an observed bandwidth for a channel associated with a receive buffer and identify a selection of a buffer-related setting from the plurality of buffer-related settings based at least in part on the observed bandwidth. In one example, each buffer-related setting includes a latency tolerance and a corresponding idle duration.
