摘要:
A computing system includes a main memory and an input/output adapter. The input/output adapter accesses a translation map. The translation map maps input/output page numbers to memory address page numbers. Entries to the translation map are generated so that each entry includes an address of a data page in the main memory and transaction configuration information. The transaction configuration information is utilized by the input/output adapter during data transactions to and from the data page.

A computing system is presented which includes a memory, an input/output adapter and a processor. The processor includes a write back cache in which dirty data may be stored. When performing a coherent write from the input/output adapter to the memory, a block of data is written from the input/output adapter to a memory location within the memory. The block of data contains less data than a full cache line in the write back cache. The write back cache is searched to determine whether the write back cache contains data for the memory location. When the search determines that the write back cache contains data for the memory location a full cache line which contains the data for the memory location is purged.

Systems, methods, and devices are provided for scoring assertions in software testing. One method embodiment includes registering assertions which fail during testing of software code. The method includes analyzing failed assertions against a set of questions. The failed assertions are scored based on analyzing the failed assertions against a set of questions.

A method, and a corresponding mechanism, are used for creating a self-describing kernel module. The method includes the steps of expressing data describing a module in a modmeta file format and creating a C language source file. The C language source file is created by translating the expressed data into a series of C language data structures, wherein the series of C language data structures comprises the C language source file. The C language source file is then compiled and linked into the module itself, thus making the module contain its own descriptive data.

Systems, methods, and device are provided for program stack handling. One method embodiment includes recognizing that a fault has occurred because a particular address range in a memory stack has been accessed. The method includes evaluating a current utilized size of regions in the memory stack. A particular address range between the current utilized size of regions in the memory stack is then relocated.

An embodiment of the invention provides an apparatus and method for management of copy-on-write faults. The apparatus and method include the acts of: assigning a translation to a first physical memory page, where the translation is a virtual memory address to physical memory address translation and where an offset portion in the translation includes a physical address of the first physical memory page; and creating a second physical memory page which is a copy of the first physical memory page.
