摘要:
Technologies for secure inter-virtual-machine shared memory communication include a computing device with hardware virtualization support. A virtual machine monitor (VMM) authenticates a view switch component of a target virtual machine. The VMM adds configures a secure memory view to access a shared memory segment. The shared memory segment may include memory pages of a source virtual machine or the VMM. The view switch component switches to the secure memory view without generating a virtual machine exit event, using the hardware virtualization support. The view switch component may switch to the secure memory view by modifying an extended page table (EPT) pointer. The target virtual machine accesses the shared memory segment via the secure memory view. The target virtual machine and the source virtual machine may coordinate ownership of memory pages using a secure view control structure stored in the shared memory segment. Other embodiments are described and claimed.

Systems and methods may provide for identifying a workload cycle for a computing platform, wherein the workload cycle is to include a busy duration and an idle duration. Additionally, platform energy consumption information may be determined for the workload cycle, and a frequency setting may be selected for the busy duration based at least in part on the platform energy consumption information.

Systems and methods for managing shared cache by multi-core processor. An example processing system comprises: a plurality of processing cores, each processing core communicatively coupled to a last level cache (LLC) slice; and a cache control logic coupled to the plurality of processing cores, the cache control logic configured to perform one of: making an LLC slice of an inactive processing core available to an active processing core or power gating the LLC slice, based on estimating cache requirements by active processing cores.

Systems and methods may provide for conducting a reward determination for a plurality of sleep states to obtain a plurality of reward determinations with respect to a device. In addition, a sleep state may be selected for the device from the plurality of sleep states based at least in part on the plurality of reward determinations. In one example, false entry and missed opportunity probabilities may be determined for stochastic interrupts, wherein the reward determination is conducted based at least in part on the false entry and missed opportunity probabilities.
摘要:
Methods and systems may provide for accumulating sensor-based information from a plurality of mobile devices and identifying context information in the sensor-based information, wherein the context information is relevant to a particular mobile device in the plurality of mobile devices. Additionally, an operational recommendation may be sent to the particular mobile device based on the context information. In one example, the operational recommendation identifies one or more of a power management action, a performance management action, a wireless interface selection and a wireless access point selection.
摘要:
Systems and methods of managing break events may provide for detecting a first break event from a first event source and detecting a second break event from a second event source. In one example, the event sources can include devices coupled to a platform as well as active applications on the platform. Issuance of the first and second break events to the platform can be coordinated based on at least in part runtime information associated with the platform.

In general, in one aspect, a method includes determining a repeated, periodic DMA (Direct Memory Access) coalescing interval based, at least in part, on a power sleep state of a host platform. The method also includes buffering data received at the device in a FIFO (First-In-First-Out) queue during the interval and DMA-ing the data enqueued in the FIFO to a memory external to the device after expiration of the repeated, periodic DMA coalescing interval.
摘要:
A method, apparatus, and system are provided for transmitting an Asynchronous Transfer Mode (ATM) cell from a server system to a broadband modem and forwarding the ATM cell from the broadband modem to a client system. According to one embodiment, a Broadband Modem Access Protocol (BMAP) unit is used to discover the identity of the broadband modem.
