摘要： A system, method and computer program product for atomically moving a shared list element from a first list location to a second list location includes inserting a placeholder element at the second list location to signify to readers that a move operation is underway, removing the shared list element from the first list location, re-identifying the list element to reflect its move from the first list location to the second list location, inserting it at the second list location and unlinking the placeholder element. A deferred removal of the placeholder element is performed following a period in which readers can no longer maintain references thereto. A method, system and computer program product are additionally provided for performing a lookup of a target list element that is subject to being atomically moved from a first list to a second list.

摘要： A method, system and computer program product for managing requests for deferred updates to shared data elements while minimizing grace period detection overhead associated with determining whether pre-existing references to the data elements have been removed. Plural update requests that are eligible for grace period detection are buffered without performing grace period detection processing. One or more conditions that could warrant commencement of grace period detection processing are monitored while the update requests are buffered. If warranted by such a condition, grace period detection is performed relative to the update requests so that they can be processed. In this way, grace period detection overhead can be amortized over plural update requests while being sensitive to conditions warranting prompt grace period detection.
摘要翻译：一种用于管理对共享数据元素的延迟更新的请求的方法，系统和计算机程序产品，同时最小化与确定是否已经删除对数据元素的预先存在的引用相关联的宽限期检测开销。缓存宽限期检测的多个更新请求，而不执行宽限期检测处理。在缓存更新请求的同时，监视可能需要开始宽限期检测处理的一个或多个条件。如果由这样的条件保证，则相对于更新请求执行宽限期检测，以便它们被处理。以这种方式，宽限期检测开销可以在多个更新请求中进行分摊，同时对需要快速宽限期检测的条件敏感。

摘要： A method and apparatus for restricting access of an application to computer hardware. The apparatus includes both an authentication module and a validation module. The authentication module is within the trusted firmware layer. The purpose of the authentication module is to verify a cryptographic key presented by an application. The validation module is responsive to the authentication module and limits access of the application to the computer hardware. The authentication modules may be implemented in software through a firmware call, or through a hardware register of the computer.

摘要： A system, method and computer program product for efficient sharing of memory between first and second applications running under first and second operating systems on a shared hardware system. The hardware system runs a hypervisor that supports concurrent execution of the first and second operating systems, and further includes a region of shared memory managed on behalf of the first and second applications. Techniques are used to avoid preemption when the first application is accessing the shared memory region. In this way, the second application will not be unduly delayed when attempting to access the shared memory region due to delays stemming from the first application's access of the shared memory region. This is especially advantageous when the second application and operating system are adapted for real-time processing. Additional benefits can be obtained by taking steps to minimize memory access faults.

摘要： A method and system for prefetching in computer system are provided. The method in one aspect includes using a prefetch engine to perform prefetch instructions and to translate unmapped data. Misses to address translations during the prefetch are handled and resolved. The method also includes storing the resolved translations in a respective cache translation table. A system for prefetching in one aspect includes a prefetch engine operable to receive instructions to prefetch data from the main memory. The prefetch engine is also operable to search cache address translation for prefetch data and perform address mapping translation, if the prefetch data is unmapped. The prefetch engine is further operable to prefetch the data and store the address mapping in one or more cache memory, if the data is unmapped.
