摘要： A computer includes a housing, a processor positioned in the housing, and an external bus adapter configured to allow the processor to access consumer electronics devices positioned outside of the housing using an external bus. The processor is configured to produce a first digital audio signal, to mix the first digital audio signal with a second digital audio signal to produce a unified digital audio signal, and to transmit the unified digital audio signal to a consumer electronics device using the external bus.

摘要： This document describes tools capable of enabling a protection agent to determine, from memory inaccessible from an operating-system privilege mode, whether one or more resources of an operating system have been modified. In some instances, these tools may enable the protection agent to reside within a virtual machine monitor. In other instances, the tools may enable the protection agent to reside within a distinct virtual partition provided by the virtual machine monitor. By operating outside of the operating-system privilege mode, the protection agent may be less vulnerable to attacks by entities operating within the operating-system privilege mode.
摘要翻译：本文档描述了能够使保护代理能够从不能从操作系统特权模式访问的存储器确定操作系统的一个或多个资源是否已被修改的工具。在某些情况下，这些工具可能使保护代理能够驻留在虚拟机监视器中。在其他情况下，这些工具可以使保护代理能够驻留在由虚拟机监视器提供的不同虚拟分区中。通过在操作系统特权模式之外操作，保护代理可能不太容易受到在操作系统特权模式下操作的实体的攻击。

摘要： An operating system is described that is capable of ascertaining whether it is executing in a virtual machine environment and is further capable of modifying its behavior to operate more efficiently and provide optimal behavior in a virtual machine environment. An operating system is enlightened so that it is aware of VMMs or hypervisors, taking on behavior that is optimal to that environment. The VMM or hypervisor informs the operating system of the optimal behavior, and vice versa.
摘要翻译：描述了能够确定其是否在虚拟机环境中执行并且还能够修改其行为以更有效地操作并在虚拟机环境中提供最佳行为的操作系统。操作系统被启发，以便它知道VMM或虚拟机管理程序，采取对该环境最佳的行为。 VMM或管理程序通知操作系统最佳行为，反之亦然。

摘要： Efficient power management of a system with virtual machines is disclosed. In particular, such efficient power management may enable coordination of system-wide power changes with virtual machines. Additionally, such efficient power management may enable coherent power changes in a system with a virtual machine monitor. Furthermore, such efficient power management may enable dynamic control and communication of power state changes.

摘要： Resource management architectures implemented in computer systems to manage resources are described. In one embodiment, a general architecture includes a resource manager and multiple resource providers that support one or more resource consumers such as a system component or application. Each provider is associated with a resource and acts as the manager for the resource when interfacing with the resource manager. The resource manager arbitrates access to the resources provided by the resource providers on behalf of the consumers. A policy manager sets various policies that are used by the resource manager to allocate resources. One policy is a priority-based policy that distinguishes among which applications and/or users have priority over others to use the resources. A resource consumer creates an “activity” at the resource manager and builds one or more “configurations” that describe various sets of preferred resources required to perform the activity. Each resource consumer can specify one or more configurations for each activity. If multiple configurations are specified, the resource consumer can rank them according to preference. This allows the resource consumers to be dynamically changed from one configuration to another as operating conditions change.

摘要翻译：描述了在计算机系统中实现的管理资源的资源管理架构。在一个实施例中，一般架构包括资源管理器和支持一个或多个资源消费者（诸如系统组件或应用程序）的多个资源提供者。当与资源管理器进行接口时，每个提供者都与资源相关联并充当该资源的管理器。资源管理员代表消费者对资源提供者提供的资源的访问进行仲裁。策略管理器设置资源管理器使用的各种策略来分配资源。一个策略是一个基于优先级的策略，区分哪些应用程序和/或用户优先于其他应用程序和/或用户来使用资源。资源消费者在资源管理器中创建“活动”，并构建一个或多个描述执行活动所需的各种首选资源集的“配置”。每个资源消费者可以为每个活动指定一个或多个配置。如果指定了多个配置，资源消费者可以根据偏好对其进行排名。这允许在操作条件改变时资源消费者从一个配置动态地改变另一个配置。

摘要： This document describes tools capable of making a portion of operating-system memory associated with a protection agent unalterable or inaccessible from an operating-system privilege mode. In some embodiments, these tools are capable of creating a protection-agent privilege mode by requesting that a virtual machine monitor protect this portion of operating-system memory. In other embodiments, these tools are capable of creating the protection-agent privilege mode by virtualizing a physical processor into multiple virtual processors, at least one of which is a protection-agent virtual processor designed to run the protection agent. By making this portion of operating-system memory unalterable or inaccessible from the operating-system privilege mode, the protection agent may be less vulnerable to attacks by entities operating within the operating-system privilege mode.
摘要翻译：本文档描述了能够使与操作系统特权模式不可更改或不可访问的保护代理相关联的操作系统内存的一部分的工具。在一些实施例中，这些工具能够通过请求虚拟机监视器保护操作系统存储器的这一部分来创建保护代理特权模式。在其他实施例中，这些工具能够通过将物理处理器虚拟化为多个虚拟处理器来创建保护代理特权模式，其中至少一个虚拟处理器是被设计为运行保护代理的保护代理虚拟处理器。通过使操作系统内存的这一部分从操作系统特权模式变得不可改变或不可访问，保护代理可能不太容易受到在操作系统特权模式下操作的实体的攻击。

In a preferred embodiment of the present invention, a memory cache is used for storing uncompressed data that is sent to or received from a compressed logical drive. When writing data to the compressed logical drive, the preferred embodiment of the present invention determines whether to use write-behind caching or write-through caching.

摘要： The present invention is directed to a facility for performing selected operations as part of a booting process of a computer system only during iterations of the booting process that immediately follow failed iterations of the booting process. At the beginning of the booting process, the facility copies a persistent instance of a flag indicating whether the iteration of the booting process at the current iteration of the booting process immediately follows fail to a temporary instance of the flag. The facility then assigns the persistent instance of the flag to the set condition so that, if the current iteration of the booting process fails before completing, the flag will reflect that the current iteration of the booting process failed. When each selected operation is encountered during the current iteration of the booting process, the facility performs that selected operation only if the temporary instance of the flag is set. If and when the current iteration of the booting process concludes successfully, the facility clears the persistent instance of the flag to reflect that the current iteration of the booting process completed successfully. In a further preferred embodiment, programs, such as the BIOS or the operating system, may set a second flag to explicitly request the performance of the selected operations during the next iteration of the booting process.
摘要翻译：本发明涉及用于仅在引导过程的迭代期间执行所选择的操作作为计算机系统的引导过程的一部分的设备，该引导过程紧随着引导过程的失败迭代。在引导过程开始时，设备复制一个标志的持久性实例，指示在引导过程的当前迭代中引导过程的迭代是否立即失败到标志的临时实例。然后，设备将标志的持久性实例分配给设置条件，以便如果引导过程的当前迭代在完成之前失败，则该标志将反映引导过程的当前迭代失败。当在引导过程的当前迭代期间遇到每个所选择的操作时，仅当设置了该标志的临时实例时，该设施才执行该选择的操作。如果引导过程的当前迭代结束，则该设施将清除该标志的持久性实例，以反映引导过程的当前迭代成功完成。在另一优选实施例中，诸如BIOS或操作系统的程序可以设置第二标志以在引导过程的下一次迭代期间显式地请求执行所选择的操作。
