摘要： A processing system includes multiple processing units. After multiple event handlers have been dispatched to execute concurrently in different processing units of the processing system in a hidden execution mode, the processing system automatically determines whether the multiple event handlers successfully complete. If an event handler among the multiple dispatched event handlers fails, the processing system automatically dispatches another event handler to perform operations associated with the event handler that failed. In an embodiment, the hidden execution mode is a system management mode (SMM), and the multiple event handlers are dispatched in response to a system management interrupt (SMI) or a platform management interrupt (PMI). In an embodiment, the processing system may determine why the dispatched event handler failed, and may performing a corrective operation before dispatching another event handler to perform the operations associated with the event handler that failed. Other embodiments are described and claimed.
摘要翻译：处理系统包括多个处理单元。在多个事件处理程序已经被调度以在隐藏的执行模式中在处理系统的不同处理单元中同时执行的情况下，处理系统自动地确定多个事件处理程序是否成功完成。如果多个分派事件处理程序中的事件处理程序发生故障，处理系统将自动调度另一个事件处理程序，以执行与失败的事件处理程序相关联的操作。在一个实施例中，隐藏执行模式是系统管理模式（SMM），响应于系统管理中断（SMI）或平台管理中断（PMI），调度多个事件处理程序。在一个实施例中，处理系统可以确定分派的事件处理程序失败的原因，并且可以在分派另一事件处理程序之前执行校正操作，以执行与失败的事件处理程序相关联的操作。描述和要求保护其他实施例。

摘要： Techniques and architectures to provide high assurance image invocation in a pre-boot environment. These techniques may augment implementations of the Unified Extensible Firmware Interface (UEFI) to invoke UEFI images using Trusted Execution Technology (TXT). This can operate to combine pre-boot secure flows, such as UEFI image invocation, with the secure launch instruction set extensions of TXT. This may entail combination of the UEFI StartImage instruction with the SMX leaf SENTER instruction. This may operate to allow original equipment manufacturer (OEM) firmware as a guard and that uses UEFI and TXT access control logic at the same instance to pass control to the operating system (OS).

摘要： In accordance with some embodiments, a single trusted platform module per platform may be used to handle conventional trusted platform tasks as well as those that would arise prior to the existence of a primary trusted platform module in conventional systems. Thus one single trusted platform module may handle measurements of all aspects of the platform including the baseboard management controller. In some embodiments, a management engine image is validated using a read only memory embedded in a chipset such as a platform controller hub, as the root of trust. Before the baseboard management controller (BMC) is allowed to boot, it must validate the integrity of its flash memory. But the BMC image may be stored in a memory coupled to a platform controller hub (PCH) in a way that it can be validated by the PCH.

摘要： Reducing memory fragmentation. Memory is allocated during a preboot phase of a computer system, wherein the memory is allocated based on a plurality of memory types. Fragmentation of memory is determined, wherein a fragment includes a contiguous block of memory of the same type. At least a portion of memory allocated to a firmware module is coalesced based on the plurality of memory types if the fragmentation is greater than a threshold. An operating system is booted by the computer system.

摘要： A system and method to resume execution of a client system from a saved system state without executing a boot-up process. A data storage unit and the client system having volatile system memory are coupled to a network. Data stored on the data storage unit is received via the network and loaded into the volatile system memory of the client system. The data contains information for the client system to resume execution from the saved system state without executing a boot-up process after a power-off state. The client system is then capable of resuming operation from the saved system state.

摘要： A method and system to switch between a Service virtual machine (VM) and a Guest VM in a virtual machine monitor (VMM) of a computer system. The VMM is loaded on the computer system to support a Service VM and a Guest VM. The Service OS is booted in the Service VM during the pre-boot phase. The Guest OS is booted in the Guest VM of the computer system. During OS runtime of the Guest OS, a VM switch is performed from the Guest VM to the Service VM without rebooting the computer system. The Service OS includes diagnostic tools to analyze the Guest OS. In one embodiment, the VM switch is performed by firmware of the computer system. In another embodiment, the VMM operates in accordance with an Extensible Firmware Interface (EFI) framework standard.
