摘要： 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.

摘要： 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.
