Abstract: A physical layer (PHY) is coupled to a serial, differential link that is to include a number of lanes. The PHY includes a transmitter and a receiver to be coupled to each lane of the number of lanes. The transmitter coupled to each lane is configured to embed a clock with data to be transmitted over the lane, and the PHY periodically issues a blocking link state (BLS) request to cause an agent to enter a BLS to hold off link layer flit transmission for a duration. The PHY utilizes the serial, differential link during the duration for a PHY associated task selected from a group including an in-band reset, an entry into low power state, and an entry into partial width state.

Abstract: Transaction data is identified and a flit is generated to include three or more slots and a floating field to be used as an extension of any one of two or more of the slots. In another aspect, the flit is to include two or more slots, a payload, and a cyclic redundancy check (CRC) field to be encoded with a 16-bit CRC value generated based on the payload. The flit is sent over a serial data link to a device for processing, based at least in part on the three or more slots.

Abstract: A reset of a synchronization counter is synchronized to an external deterministic signal. Entry into the link transmitting state is further synchronized with the deterministic signal. A target latency is identified for a serial data link. A data sequence is received synchronized with a synchronization counter associated with the data link. Target latency can be maintained using the data sequence.

Abstract: A request is received that is to reference a first agent and to request a particular line of memory to be cached in an exclusive state. A snoop request is sent intended for one or more other agents. A snoop response is received that is to reference a second agent, the snoop response to include a writeback to memory of a modified cache line that is to correspond to the particular line of memory. A complete is sent to be addressed to the first agent, wherein the complete is to include data of the particular line of memory based on the writeback.

Abstract: A supersequence corresponding to an initialization state is received on a link that includes a repeating pattern of an electrical idle exit ordered set (EIEOS) followed by a number of consecutive training sequences. Instances of the EIEOS are to be aligned with a rollover of a sync counter. A latency value is determined from one of the EIEOS instances in the supersequence and latency is added to a receive path of the link through a latency buffer based on the latency value.
