摘要： Various aspects are disclosed herein for bounding the behavior of a non-privileged virtual machine that interacts with a device by creating a description of the device which indicates to a privileged authority (1) which operations on the device may have system-wide effects and (2) which operations have effects local to the device. The privileged authority may then permit or deny these actions. The privileged authority may also translate these actions into other actions with benign consequences.

摘要： Various aspects are disclosed herein for replacing the hardware backing the memory locations associated with a virtual machine with a backing mechanism. The backing mechanism may have the memory locations appear to contain data convenient to the driver in the virtual machine, typically containing what the hardware would have returned if the hardware had been read from. The data image being returned from the memory locations may travel with the virtual machine even if the virtual machine moves to a different physical machine that does not contain hardware equivalent to the hardware that was recently removed from the virtual machine.

摘要： A method and system are provided for integrating partitions in a virtual machine environment. Specifically, a partition bus is provided, where the partition bus operatively connects partitions in such a way that it functions as a data transport mechanism allowing for data transfer and device sharing between partitions. The partition bus relies on virtualizing software in order to establish itself and to establish channels of communication between partitions and to inject interrupts to partitions where it is appropriate to do so. Furthermore, the partition bus employs such mechanisms ring buffers, transfer pages, and memory map changes to transfer information (requests and data). Furthermore, it uses policy agents to decide when information should be transferred or when devices should be shared among partitions. Lastly, it employs various mechanisms to ensure smooth integration between partitions, which includes remote services that have proxy devices and device versioning functionalities.

摘要： The subject invention relates to systems and methods for automatic recovery from errors in a computing environment. A system is provided to facilitate failure recovery in the computing system. The system includes at least one driver component that enumerates at least one layer of a driver stack. A module associated with the driver component requests re-enumeration of the driver stack upon detection of an error in the computing system. When an error is detected by a driver or operating system component, a protocol can be established whereby a new copy of the driver's stack or system resources is re-enumerated in parallel to existing resources that may be in an unknown or error state. The new copy of the stack may allow the driver to become operational in lieu of the previous stack which can be reclaimed for other system uses over time.

摘要： The present invention provides a unified layer for Plug and Play (PnP) components and power management components while relieving device drivers from system-level complexities associated with implementing PnP and/or power management functionality. The layer operates at a level between low-level device drivers and more complex operating system tasks. The subject invention simplifies designing device drivers having proper power management support by creating an infrastructure that allows a device driver to operate within a driver framework or model and without having to process Plug-and-Play or Power Management I/O Request Packets (IRPs) directly.

摘要： A method and system that enables customized computer machines to be more readily developed by removing the function of resource translation out of the hardware abstraction layer (HAL). A machine manufacturer describes a machine in firmware, such as accordance with the Advanced Configuration and Power Interface (ACPI) specification, using ACPI machine language (AML). Operating system components such as a Plug and Play (PnP) manager in the kernel, in conjunction with an ACPI driver, interpret the description information and locate resources (bus bridges) for which translation is needed. For any arbitrary bus architecture or CPU to PCI bridge implementation that can be expressed, e.g., in ACPI firmware, the invention provides a translator external to the HAL. In one implementation, a PnP driver communicates with the ACPI driver and various drivers in driver stacks via I/O request packets (IRPs) to look for resource translators. The ACPI driver analyzes the machine description and returns a translator if found for such a resource. The resource is then configured to output cycles based on the translator.
摘要翻译：一种方法和系统，通过从硬件抽象层（HAL）中移除资源转换的功能，可以更容易地开发定制的计算机机器。机器制造商根据使用ACPI机器语言（AML）的高级配置和电源接口（ACPI）规范来描述固件中的机器。操作系统组件，如内核中的即插即用（PnP）管理器，与ACPI驱动程序一起，解释描述信息并定位需要翻译的资源（总线桥）。对于可以表达的任何任意总线架构或CPU到PCI桥的实现，例如在ACPI固件中，本发明提供了在HAL外部的翻译器。在一个实现中，PnP驱动程序通过I / O请求数据包（IRP）与ACPI驱动程序和驱动程序堆栈中的各种驱动程序进行通信，以查找资源翻译器。 ACPI驱动程序分析机器描述，并返回一个翻译器，如果找到这样的资源。然后将资源配置为基于转换器输出周期。

摘要： A computing device has first and second virtual machines (VMs) and a resource assigned to the first VM. Each access request for the resource is forwarded thereto until the first VM is to be saved or migrated. Thereafter, each access request is forwarded to a holding queue. When the resource has acted upon all access requests forwarded thereto, the resource is reassigned to the second VM, and each access request at the holding queue is forwarded to the second VM and then the resource. Thus, all access requests for the resource are acted upon by the resource even after the resource is removed from the first VM and assigned to the second VM, and the save or migrate of the first VM can thereafter be completed.

摘要： A mechanism for simulating the existence of hardware in a configuration and power management system is described. In one aspect, a simulator interfaces with the configuration and power management system to generate simulated events. In another aspect, accesses to hardware registers are simulated by registering the simulator with the configuration and power management system to handle accesses to a simulated hardware device. A component within the configuration and power management system may define the simulated hardware device such that accesses to the simulated hardware device occur with respect to a defined I/O space.
