摘要： A system is provided that includes a computing device operable to render video content for display on a display device and to periodically refresh that display device. The video content includes at least one application window. A desktop compositor is operable to wake and execute commands to compose video frames that are composited surfaces that include the at least one application window and to initiate a buffer flip to deliver the video frames to the display device. A high resolution timer is operable to cause the desktop compositor to wake and execute the commands in multiple instances between display refreshes.

摘要： A server kernel processing system receives an input/output (I/O) request from a user mode computing environment. The I/O request is analyzed to determine whether it is a file open request. If so, target analysis logic determines whether the file open request is for a driver file or for a file within a protected volume that stores a driven whitelist file. If the file open request is for a file stored in a protected volume, the request is blocked. If the file open request is for a driver file, then the driver whitelist file is examined to determine whether the target driver is on the whitelist. If not, the file open request is also blocked.

摘要： Methods and systems for managing operation of data processing systems are disclosed. To manage operation of the data processing systems, the data processing systems may present unified communication and management systems. The unified communication and management systems may be used to manage the operation of any number of management controller embedded devices hosted by the data processing systems. The unified communication and management systems may allow for communication with and management of the management controller embedded devices without requiring that the management systems directly interact with the management controller embedded devices.

摘要： Embodiments of this application provide a method and an apparatus for determining virtual machine VM migration. The method includes: after a VM is migrated, sending a gratuitous ARP packet or a RARP packet to an in-migration VTEP device; obtaining, by the VTEP device, a MAC address of the VM, searching an ARP cache table based on the MAC address, and obtaining an IP address of the VM; and constructing an ARP unicast request packet by using the IP address as a destination IP address, and if the VTEP device receives an ARP response packet sent by the VM for the ARP unicast request packet, determining that the VM is migrated.

摘要： Scalable life-cycle maintenance of hardware. In an embodiment, a software-defined Preboot eXecution Environment (PXE) server is executed to receive a request, comprising an identifier, from hardware. The identifier is compared to a plurality of attribute sets. When the identifier does not match any of the attribute sets, a task graph is generated for a PXE process for the hardware, and an initial stage of the task graph is initiated. Otherwise, when the identifier matches one of the attribute sets, the task graph associated with that attribute set is retrieved, and the a next stage in the task graph is initiated. In addition, a display key may be used to tether hardware with a user system. Furthermore, hardware may be validated by comparing signatures using a validating operating system, and a boot order of operating systems in the hardware may be changed once the hardware device is validated.

摘要： A processor core energy-efficiency core ranking scheme akin to a favored core in a multi-core processor system. The favored core is the energy-efficient core that allows an SoC to use the core with the lowest Vmin for energy-efficiency. Such Vmin values may be fused in appropriate registers or stored in NVM during HVM. An OS scheduler achieves optimal energy performance using the core ranking information to schedule certain applications on the core with lowest Vmin. A bootstrap flow identifies a bootstrap processor core (BSP) as the most energy efficiency core of the SoC and assigns that core the lowest APIC ID value according to the lowest Vmin. Upon reading the fuses or NVM, the microcode/BIOS calculates and ranks the cores. As such, microcode/BIOS calculates and ranks core APIC IDs based on efficiency around LFM frequencies. Based on the calculated and ranked cores, the microcode or BIOS transfers BSP ownership to the most efficiency core.

摘要： A data processing system comprises a processing core to execute a basic input/output system (BIOS) as part of a boot process. The data processing system also comprises static random-access memory (SRAM) in communication with the processing core. The data processing system also comprises a pre-BIOS component in communication with the SRAM. The pre-BIOS component is configured to execute a pre-BIOS block before the processing core begins executing the BIOS. The pre-BIOS block, when executed by the pre-BIOS component, causes the pre-BIOS component to (a) initialize the pre-BIOS component, (b) measure an amount of time taken to initialize the pre-BIOS component, and (c) save the measured amount of time to the SRAM as a pre-BIOS boot-time record. Other embodiments are described and claimed.

摘要： Techniques and architecture are described for validating and verifying iPXE scripts prior to execution during a booting process. During the booting process of a network device, right after the UEFI/BIOS stage of the booting process, a trusted iPXE script may make a request to a network server for the ownership voucher and owner certificate of the network device. The ownership voucher and owner certificate may then be stored in a trusted platform module (TPM) on the network device. In configurations, the retrieved owner certificate may be validated by the ownership voucher. The owner certificate may be used to validate iPXE scripts. Once validated, the iPXE scripts may be executed and the booting process may be continued to the kernel loading step and the application loading step. During a subsequent booting process of the network device, the ownership voucher and owner certificate may be retrieved from the TPM.
