    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.

    摘要: 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 determining quality of service (QoS) information for a job associated with an application, and determining a condition prediction for a wireless channel of a mobile platform. Additionally, the job may be scheduled for communication over the wireless channel based at least in part on the QoS information and the condition prediction. In one example, scheduling the job includes imposing a delay in the communication if the condition prediction indicates that a throughput of the wireless channel is below a threshold and the delay complies with a latency constraint of the QoS information.
