摘要： Communication of information via an in-band channel using a trusted configuration space is provided. The introduction of using a trusted configuration space associated with a computer bus system, such as PCI Express® (PCIe™), for example, enables the design of trusted computing platforms capable of providing compliant devices with assurance that their trusted configuration registers can only be accessed by software running in the trusted software environment. Establishing device trust in the software that initiates trusted configuration requests makes it possible to secure and control access to certain secret, sensitive, or personally-identifiable information these devices may contain (e.g., a uniquely-identifying public key, as described above or certificate which the device provides for revocation purposes).

摘要： The launching of a hypervisor after there is already a running operating system. The operating system itself may launch the hypervisor. The running operating system may be used instead of the hypervisor to discover the physical resources running on the computing system. Other operating systems or operating system instances may be launched after the hypervisor is operational.

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： An interrupt arbiter for a computer is described. The arbiter allocates interrupt resources to a plurality of devices within a computer such as a modem, keyboard, video controller, serial port, PCMCIA card, etc. As devices request interrupt resources, the inventive arbiter uses the Advanced Configuration and Power Interface (ACPI) to allocate interrupt resources based on the actual hardware topology of the computer. The improved arbiter allocates the interrupt resources by using configuration information that conforms to the ACPI specification and that describes the underlying connection circuitry, such as the multiplexors, routers, switches, etc., that communicates interrupt signals generated by the devices. In addition, the arbiter reconfigures connection circuitry of the computing system when necessary in order to improve the allocation of interrupt resources.
