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: A link layer control message is generated and included in a flit that is to be sent over a serial data link to a device. The flits sent over the data link are to include a plurality of slots. Control messages can include, in some aspects, a viral alert message, a poison alert message, a credit return message, and acknowledgements.

Abstract: A periodic control window is embedded in a link layer data stream to be sent over a serial data link, where the control window is configured to provide physical layer information including information for use in initiating state transitions on the data link. The link layer data can be sent during a link transmitting state of the data link and the control window can interrupt the sending of flits. In one aspect, the information includes link width transition data indicating an attempt to change the number of active lanes on the link.

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.
