    Abstract: A ring interface is coupled to a current node in a ring network having a plurality of nodes and corresponding ring interface for each of said nodes. The ring interface includes a ring input port operative to conduct upstream message packets from a previous node to the ring interface, a ring output port operative to conduct message packets to a next node of the ring network, and a bypass queue operative to buffer message packets. A receive queue buffers message packets before passing them on to the current node. An address filter is coupled to the ring input port to receive the upstream message packets, read their destination addresses and pass them to the bypass queue if the addresses correspond to another node and pass them to the receive queue if their addresses are that of the current node. A transmit queue buffers message packets from the current node and a bypass-transmit queue arbiter is coupled to outputs of the bypass queue and the transmit queue and is operative to select message packets from one of the bypass queue and the transmit queue in accordance with predetermined selection criterion and transmits the selected message packets to the ring output port.

    Abstract: Detecting and flushing maximal length packets is set forth herein. In one embodiment, the method comprises receiving a flushing event and, in response to the flushing event, repeatedly detecting a maximum length packet of write data from a write combining storage area and flushing the detected maximum length packet to a target input/output (I/O) device over a bus. Each maximal length packet is a packet of maximum payload of write data that can be formulated within in the write combining storage area while adhering to packet protocol rules for the bus.

    Abstract: In one embodiment, the present invention includes power control logic for squelch detection circuitry to enable selective enabling of one or more squelch detection circuits of an interconnect interface in a low power mode. The logic may include a squelch mode control register to select a first mode or a second mode of power control, a second register coupled to the squelch mode control register to receive software settings to indicate which squelch detect circuit(s) to disable in a low power state of the interconnect, and a detector to dynamically detect a logical lane zero of the interconnect in the second mode. Other embodiments are described and claimed.
