摘要: Methods and apparatus relating to home agent data and memory management are described. In one embodiment, a scrubber logic corrects an error at a location in a memory corresponding to a target address by writing back the corrected version of data to the target location. In an embodiment, a map out logic maps out an index or way of a directory cache in response to a number of errors, corresponding to the directory cache, exceeding a threshold value. Other embodiments are also disclosed.

摘要: Methods and apparatus relating to memory mirroring and migration at a Home Agent (HA) are described. In one embodiment, a home agent may mirror its data at a slave agent. In some embodiments, a bit in a directory may indicate status of cache lines. Other embodiments are also disclosed.
摘要翻译: 描述了与归属代理(HA)的内存镜像和迁移有关的方法和设备。 在一个实施例中,归属代理可以在从属代理处镜像其数据。 在一些实施例中,目录中的位可以指示高速缓存行的状态。 还公开了其他实施例。

摘要: In one embodiment, a method includes receiving a read request from a first caching agent and if a directory entry associated with the request is in an unknown state, an invalidating snoop message is sent to at least one other caching agent to invalidate information in a cache location of the other caching agent corresponding to the location of the read request, to enable setting of the directory entry into a known state. Other embodiments are described and claimed.

摘要: In a bus interface adapted for usage in a multiple-core processor, an interface couples a bus to the one or more processor cores. The bus interface comprises a queue coupled to the interface which is adapted to receive snoop responses from the processor cores and coalesce snoop responses from the processor cores into a single snoop response that reflects snoop responses from all processor cores.
