Abstract: A transmitting device and a receiving device are coupled via a high-speed serial interface within a computer system. The transmitting device transmits a packet header for a message request transaction that include a message group sub-field that indicates one of a plurality of message groups. The packet header also includes a format field that indicates whether the message request packet includes data. The packet header further includes a message code field to indicate a specific message type.

Abstract: A method and apparatus for enhancing/extending a serial point-to-point interconnect architecture, such as Peripheral Component Interconnect Express (PCIe) is herein described. 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: A storage device is provided to maintain a value of flow control credits allocated for a device on a channel and flow control logic is provided to receive a flow control signal over a link of an interconnect, the flow control signal indicating flow control credits allocated for the device on the channel. The flow control logic is further to update the value of flow control credits based on activity of the device on the channel.

Abstract: A general input/output communication port implements a communication stack that includes a physical layer, a data link layer and a transaction layer. The transaction layer includes assembling a packet header for a message request transaction to one or more logical devices. The packet header includes a format field to indicate the length of the packet header and to further specify whether the packet header includes a data payload, a subset of a type field to indicate the packet header relates to the message request transaction and a message field. The message field includes a message to implement the message request transaction. The message includes at least one message that is selected from a group of messages.

Abstract: Embodiments of the invention are generally directed to systems, methods, and apparatuses for encapsulation of high definition audio data over an input/output interconnect. In some embodiments, a system includes tunneling logic coupled with a high definition (HD) audio controller. The tunneling logic may receive digital audio data from the HD audio controller, encapsulate the digital audio data in a message suitable for an in-band input/output (IO) interconnect, and send the message to an add-in graphics card via the in-band input/output IO interconnect. Other embodiments are described and claimed.

Abstract: An enhanced general input/output communication architecture, protocol and related methods are presented. In one embodiment, a method for an enhanced general input/output communication architecture includes initializing a flow control mechanism within an general input/output (GIO) interface associated with a virtual channel upon initialization of the virtual channel, and tracking receive buffer availability in a remote GIO interface coupled with the GIO interface by the virtual channel by monitoring an indication associated with an amount of content transmitted from the GIO interface to the remote GIO interface.
