摘要： An interface for coupling an agent to a fabric supports a load/store interconnect protocol, where the I/O interconnect protocol includes a flit mode and a non-flit mode. A set of flit mode header formats are used when in the flit mode and a set of non-flit mode header formats are used when in the non-flit mode, the set of non-flit mode header formats including one or more non-flit mode fields. Interface logic determines that a link is trained to the non-flit mode and generates a header according to the set of flit mode header formats, where the header includes a field to indicate that a corresponding packet originated as a non-flit mode packet. One or more fields of the set of flit mode header formats are repurposed in the header to carry the one or more non-flit mode fields before sending the modified header over the interface.

摘要： Embodiments herein relate to an electronic device with an interface an interface to communicatively couple with a second electronic device via a communication link, and a link controller. The link controller may be configured to identify, from the second electronic device over the communication link, a flit related to a request from the second electronic device to access a resource of the first electronic device, wherein the flit is an element of a message authentication code (MAC) epoch; generate, based on the flit, a cache/mem interface message related to the request, wherein the cache/mem interface message includes an indication of the MAC epoch; and transmit, to a device fabric of the first electronic device, the cache/mem interface message prior to receipt of a MAC related to the MAC epoch. Other embodiments may be described and/or claimed.
