摘要： A processing system includes memory management software responsive to a translation lookaside buffer miss. The memory management software updates translation lookaside buffer information based on one or more missed virtual addresses. Entries of a first translation lookaside buffer are updated by the memory management software with information corresponding to the missed virtual addresses if memory page size information for the missed virtual addresses meet a first criterion. Entries of a second translation lookaside buffer are updated by the memory management software with information corresponding to the missed virtual addresses if memory page size information for the missed virtual addresses meet a second criterion. The first and second criterion may correspond to first and second memory page sizes supported by the respective translation lookaside buffers.

摘要： A processing system includes memory management software responsive to changes in a page table. The memory management software consolidates contiguous page table entries into one or more page table entries that have larger memory page sizes. The memory management software updates the entries of a translation lookaside buffer that correspond to the consolidated contiguous page table entries.

摘要： A processing system is set forth that includes a processor, read only memory storing an operating system image file accessible by the processor, and random access memory that is also accessible by the processor. The processing system also includes a boot program that is executable by the processor to initialize the processing system in response, for example, to a power-on event, reset event, or a wake-up event. A power-on event occurs when power is initially provided to the processing system while a wake-up event occurs when the processing system is to exit a low-power mode of operation. A reset event occurs when, for example, a fault is detected that causes the system to restart. The boot program selectively performs a full boot copy of the operating system image file from the read only memory to the random access memory or a fast boot copy of only predetermined portions of the operating system image file from the read only memory to the random access memory. For example, the boot program may execute the full boot copy operation in response to the power-on event and the fast boot copy operation in response to the wake-up event and/or reset event. Further, the boot program may limit execution of the fast boot copy operation to those instances in which the random access memory passes an integrity check of the contents of one or more areas containing selected portions of the operating system copied from the read only memory during a prior full boot copy operation.
摘要翻译：提出了一种处理系统，其包括处理器，存储可由处理器访问的操作系统映像文件的只读存储器和也可由处理器访问的随机存取存储器。处理系统还包括可由处理器执行的引导程序，以便例如响应于开机事件，复位事件或唤醒事件来初始化处理系统。当处理系统要退出低功耗操作模式时，在唤醒事件发生时，最初向处理系统提供电源时发生上电事件。当检测到例如导致系统重新启动的故障时，会发生复位事件。引导程序选择性地将操作系统映像文件的完整启动副本从只读存储器执行到随机存取存储器，或仅将操作系统映像文件的预定部分从只读存储器快速启动拷贝到随机存取存储器。例如，响应于唤醒事件和/或复位事件，引导程序可以响应于开机事件和快速启动复制操作来执行完全启动复制操作。此外，引导程序可以将快速启动复制操作的执行限制于那些随机访问存储器在一个或多个区域的内容通过对从只读存储器复制的操作系统的所选部分的内容的完整性检查的情况下以前全面启动复制操作。

摘要： A system for meeting demanding boot time requirements, such as those timing requirement mandated by vehicle telematics systems, is described. Current computer systems use expensive hardware like coprocessors to service requests, such as input/output requests, that have timing requirements which are less than the time required to load the operating system into memory. Instead, a mini-driver may be initialized early in the boot process before the operating system is loaded, to service these requests. For example, the mini-driver may buffer incoming data, and/or reply to incoming messages. After the operating system has loaded, a second device driver may be initialized, and the mini-driver may be transitioned to the second driver.

摘要： A file management system for use with a computer system is disclosed. The file management system comprises a real filesystem for accessing files stored on a storage medium and a custom filesystem. The custom filesystem comprises a hierarchical arrangement of links to a subset of files of the real filesystem. In operation, the custom filesystem has processing priority over the real filesystem. As such, the custom filesystem processes requests relating to files of the file subset prior to processing, if any, of the requests by the real filesystem.

摘要： A system includes a processor, one or more memory storage units, and software code stored in the memory storage units. The software code is executable by the processor to generate a plurality of adaptive partitions that are each associated with one or more process threads. Each of adaptive partition has one or more corresponding assigned scheduling attributes. The software code includes a scheduling system for selectively allocating the processor to run process threads based on a comparison between ordering function values for each adaptive partition. Ordering function values are calculated based on scheduling attributes of the corresponding adaptive partition. A critical ordering function value also may be calculated and used to determine the proper manner of billing an associated adaptive partition for the processor allocation used to run its associated critical threads. Methods of implementing various aspects of such a system are also set forth.

摘要： An improved distributed operating system over a network of computer systems is described. Existing distributed operating systems have transmission performance limitations dictated by their inability to (1) reliably handle transient communication failures and rapid node reboots, (2) provide a transmission protocol that adapts to link reliability, and (3) allow transmissions to occur over an arbitrary combinations of communication links. The systems and methods described herein solve these problems by providing a reliable node-to-node session protocol that offers high performance message delivery and multi-interface management and support. This is done by transmitting all data between two nodes of the operating system over a single connection that may dynamically exploit multiple interfaces between the nodes.
