Temporal and locality caching hints and prefetching hints are provided to improve system wide caching and prefetching. Message codes for atomic operations to arbitrate ownership between system devices/resources are included to allow efficient access/ownership of shared data. Loose transaction ordering provided for while maintaining corresponding transaction priority to memory locations to ensure data integrity and efficient memory access. Active power sub-states and setting thereof is included to allow for more efficient power management. And, caching of device local memory in a host address space, as well as caching of system memory in a device local memory address space is provided for to improve bandwidth and latency for memory accesses.

Abstract: In one embodiment, the present invention includes a memory management unit (MMU) having entries to store virtual address to physical address translations, where each entry includes a location indicator to indicate whether a memory location for the corresponding entry is present in a local or remote memory. In this way, a common virtual memory space can be shared between the two memories, which may be separated by one or more non-coherent links. Other embodiments are described and claimed.

Abstract: A device, method, and system are disclosed. In one embodiment the device includes a router to transmit data packets between multiple host controllers and one or more peripheral devices. The router can receive a data packet from a host controller and transmit the data packet to a peripheral device across a data transmission path. The peripheral device is coupled to the first data transmission path through a first universal multi-transport medium (UMTM) connector. The connector includes an optical coupling capable of transporting the first data packet within an optical signal and an electrical coupling capable of transporting the first data packet within an electrical signal.
