    Abstract: 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.

    Abstract translation: 用于安全的虚拟机间共享存储器通信的技术包括具有硬件虚拟化支持的计算设备。 虚拟机监视器（VMM）验证目标虚拟机的视图切换组件。 VMM添加配置安全内存视图以访问共享内存段。 共享内存段可以包括源虚拟机或VMM的存储器页面。 视图切换组件切换到安全存储器视图，而不会使用硬件虚拟化支持生成虚拟机退出事件。 视图切换组件可以通过修改扩展页表（EPT）指针来切换到安全存储器视图。 目标虚拟机通过安全内存视图访问共享内存段。 目标虚拟机和源虚拟机可以使用存储在共享存储器段中的安全视图控制结构来协调存储器页的所有权。 描述和要求保护其他实施例。

    Abstract: For example, a wireless communication device may be configured to determine an expected interference-based value corresponding to an Uplink (UL) transmission from a wireless communication station (STA) in a Trigger-Based (TB) Multi-User (MU) UL transmission to be communicated from a plurality of STAs to the wireless communication device; to determine one or more transmit (Tx) configuration parameters for the STA based on the expected interference-based value corresponding to the UL transmission from the STA; and to transmit a trigger frame to trigger the TB MU UL transmission, the trigger frame including the one or more Tx configuration parameters to configure the UL transmission from the STA.

    Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of a wakeup packet response. For example, an apparatus may include circuitry configured to cause a first wireless device to transmit a frame comprising mapping information to map a plurality of Modulation and Coding Schemes (MCS) to a respective plurality of preamble lengths; generate a wakeup packet comprising a preamble having a preamble length of the plurality of preamble lengths corresponding to an MCS of a non-wakeup transmission from the first wireless device; and transmit the wakeup packet to a second wireless device.

    Abstract: Devices and techniques for out-of-band platform tuning and configuration are described herein. A device can include a telemetry interface to a telemetry collection system and a network interface to network adapter hardware. The device can receive platform telemetry metrics from the telemetry collection system, and network adapter silicon hardware statistics over the network interface, to gather collected statistics. The device can apply a heuristic algorithm using the collected statistics to determine processing core workloads generated by operation of a plurality of software systems communicatively coupled to the device. The device can provide a reconfiguration message to instruct at least one software system to switch operations to a different processing core, responsive to detecting an overload state on at least one processing core, based on the processing core workloads. Other embodiments are also described.

    Abstract: Various embodiments are generally directed to techniques for improving the efficiency of exchanging packets among multiple VMs within a communications server, and between the communications server and other devices in a communications system. An apparatus may include a virtual switch to analyze contents of at least one packet of a set of packets to be exchanged between endpoint devices through a network, and to correlate the contents to a pathway to extend through one or more of the VMs that are each configured as virtual servers of multiple virtual servers; and an interface control component to select at least one virtual network interface of each of the one or more virtual servers along the pathway to operate in a polling mode, and to select a virtual network interface of at least one virtual server of the multiple virtual servers not along the pathway to operate in a non-polling mode.
