    摘要: Methods and apparatus for efficient peer-to-peer communication support in interconnect fabrics. Network interfaces associated with agents are implemented to facilitate peer-to-peer transactions between agents in a manner that ensures data accesses correspond to the most recent update for each agent. This is implemented, in part, via use of non-posted “dummy writes” that are sent from an agent when the destination between write transactions originating from the agent changes. The dummy writes ensure that data corresponding to previous writes reach their destination prior to subsequent write and read transactions, thus ordering the peer-to-peer transactions without requiring the use of a centralized transaction ordering entity.

    摘要: In one embodiment, a processor includes a first cache and a second cache, a first core associated with the first cache and a second core associated with the second cache. The caches are of asymmetric sizes, and a scheduler can intelligently schedule threads to the cores based at least in part on awareness of this asymmetry and resulting cache performance information obtained during a training phase of at least one of the threads.

    摘要: In one embodiment, a cache memory includes entries each to store a ring level identifier, which may indicate a privilege level of information stored in the entry. This identifier may be used in performing read accesses to the cache memory. As an example, a logic coupled to the cache memory may filter an access to one or more ways of a selected set of the cache memory based at least in part on a current privilege level of a processor and the ring level identifier of the one or more ways. Other embodiments are described and claimed.
