摘要： A system and method for sharing resources between real-time and virtualizing operating systems is presented. A computer system uses effective address mapping of support processors' local memory to share resources between separate operating systems. When threads are created for either operating system, the thread's corresponding processor memory is mapped into an effective address space. In doing so, the processor's local memory is accessible by the thread, regardless of whether the processor is running, or whether the processor is executing a different thread from a different operating system. For example, a computer system may have eight support processors and running two operating systems whereby the first operating system requires six support processors and the second operating system requires all eight support processors. In this example, resources are virtualized and shared between the two operating systems in order to meet the requirements of both operating systems.

摘要： An approach that optimizes system performance using performance monitors is presented. The system gathers thread performance data using performance monitors for threads running on either a first ISA processor or a second ISA processor. Multiple first processors and multiple second processors may be included in a single computer system. The first processors and second processors can each access data stored in a common shared memory. The gathered thread performance data is analyzed to determine whether the corresponding thread needs additional CPU time in order to optimize system performance. If additional CPU time is needed, the amount of CPU time that the thread receives is altered (increased) so that the thread receives the additional time when it is scheduled by the scheduler. In one embodiment, the increased CPU time is accomplished by altering a priority value that corresponds to the thread.

摘要： A system and method is provided to improve software simulation. A software emulator is used in conjunction with a hardware simulator. A special snapshot instruction is included in the software code that is emulated. When the snapshot instruction is encountered, values such as register, memory, and program stack values, are stored creating an initial snapshot. Code continues to be emulated and, when the next snapshot instruction is encountered, the values are written to create a second snapshot. The initial values are used to set an initial state in a hardware model that is simulated on a hardware simulator. The results of the hardware simulation are compared to the second snapshot to uncover software errors and/or hardware errors so that the software can be modified or the hardware design can be modified. Multiple sets of snapshots can be taken to analyze multiple sections of the software program.

摘要： Initially, a SMI trap detects an application accessing a memory location associated with a physical hardware device. The SMI trap receives the device address for the address bus and compares that address with memory addresses for hardware devices being virtualized by virtual device simulators. If the address matches an available virtual device, the SMI caches the address, hooks and caches the corresponding IO instruction for the memory address and issues a SMI. A SMI handler receives the SMI and determines which virtual device simulator to call. Once activated by the SMI handler, the virtual device simulator interacts with the application and then returns control to the processor.

摘要： A method and system for automatically configuring a boot process of a network computer initially connected within a network comprising at least one server. A request is broadcast from a network computer to a network for an available server, upon a first initiation of the network computer within the network. Responses from the broadcast are gathered which indicate whether a server is available. A selected boot program is then executed from among multiple boot programs available in the network computer. The selected boot program and the identity of an available server are stored as boot process configuration settings in a nonvolatile storage of the network computer, in response to successful execution of the boot program, such that a subsequent boot process of a network computer is automatically configured.

摘要： A computer system including a processor, a system memory, and a boot code storage device. The system memory is connected to the processor and is suitable for storing processor data and instructions. The boot code storage device includes an image selection indicator for indicating which of multiple boot code images are to be loaded. The computer system further includes means for initiating a boot sequence stored on the boot code storage device. The boot sequence selects from first and second boot images based upon the state of the image selection indicator and loads the selected image into the system memory in response to a boot event. In one embodiment, the image selection indicator is in an initial state until the boot code sequence successfully loads a boot image. The image selection indicator is set to a value indicative of the loaded image when one of the boot images is successfully loaded. The boot code storage sequence attempts, in the preferred embodiment, to load the previously load boot image when the system detects a setting of the image selection indicator indicative of a previously loaded boot image. In the preferred embodiment, the boot code sequence responds to a specified user input sequence by presenting the user with a configuration screen suitable for altering the value of the image selection indicator such that the user may later the boot image that will be loaded during a subsequent execution of the boot sequence. In one embodiment, the first boot image is a BIOS based boot image and the second image is a network based (non-BIOS) boot image. The boot code storage device is preferably a flash memory device.
