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.

High performance interconnect

Embodiments of an invention for securing transmissions between processor packages are disclosed. In one embodiment, an apparatus includes an encryption unit to encrypt first content to be transmitted from the apparatus to a processor package directly through a point-to-point link.

Securing data transmission between processor packages

The present application is directed to establishing ownership of a secure workspace (SW). A client device may provide a SW data structure (SWDS) to a SW configurator. A SWDS may comprise a hash of an original SW and a public key, and may be signed by a private key corresponding to the public key. The SW configurator may cause an execution container (EC) to be generated including a SW initiated using the SWDS. The client device may claim SW ownership using a request (signed by the private key) transmitted along with a copy of the public key. SW ownership may be determined by an ownership determination module that verifies the signature of the request using the public key received with the request, determines a hash of the received public key and compares the hash of the received public key to a hash of the public key in the SWDS.
