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： Page tables in the last level of a hierarchical page table system are scanned for candidate page tables. Candidate page tables are converted to large pages, having a page table entry in a level before the last level of the hierarchical page table system adjusted to be associated with the newly created large page. Upon receiving a notification that a large page is to be converted into a page table, a new page table is created. Each entry in the new page table is associated with a small segment of memory in the large page and an entry in a page table one level before the last level in a hierarchical page table system is adjusted to be associated with the new page table.

摘要： Techniques for grouping individual processors into assignment entities are discussed. Statically grouping processors may permit threads to be assigned on a group basis. In this manner, the burden of scheduling threads for processing may be minimized, while the processor within the assignment entity may be selected based on the physical locality of the individual processors within the group. The groupings may permit a system to scale to meet the processing demands of various applications.

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。

摘要： A method and system for transitioning the operating mode and networking components of a network workstation from one mode of operation to another is described herein. In a disclosed embodiment, a method and system is described for transitioning a workstation from operating under a real mode operating system (with real mode network components) to operating under a protected mode operating system (with protected mode network components). A transition program preserves the state of the workstation before the real mode network components are loaded therein and enabled. The real mode network components are then enabled and utilized to transfer to the workstation memory the protected mode operating system and protected mode network components from the network. After the transfer, the transition program disables the real mode network components, restores the pre-real mode state of the workstation, and enables the protected mode network components. The memory allocated for the real mode network components may then be reclaimed.
摘要翻译：本文描述了一种用于将网络工作站的操作模式和网络组件从一种操作模式转换到另一种操作模式的方法和系统。在公开的实施例中，描述了一种方法和系统，用于将工作站从实模式操作系统（具有实模式网络组件）运行到在受保护模式操作系统（具有保护模式网络组件）下运行。过渡程序在实模式网络组件加载并启用之前保留工作站的状态。然后启用和使用实模式网络组件将保护模式操作系统和保护模式网络组件从网络传送到工作站存储器。传输后，转换程序禁用实模式网络组件，恢复工作站的预实模状态，并启用保护模式网络组件。然后可以回收为实模式网络组件分配的内存。

摘要： A ring buffer in accordance with the invention includes a plurality of registers that form a circular sequence of registers. A write pointer references one of the registers. A plurality of read pointers correspond respectively to a plurality of data consumers. Each read pointer references one of the registers. Upon receiving a new data element, the data element is written to the register that is referenced by the write pointer, and the write pointer is advanced. Upon receiving a request from a data consumer, a data element is read from the register referenced by the read pointer corresponding to the data consumer, and the read pointer is advanced.
