摘要:
A middle manager and methods are provided to enable a plurality of host devices to share one or more input/output devices. The middle manager initializes each shared input/output device and binds one or more functions of each input/output device to a specific host node in the system, such that hosts may only access functions to which they are bound. The middle manager may also utilize a configuration register map to translate values from the actual configuration register into a unique modified value for each of the plurality of host devices such that each host device may access and use the shared input/output device regardless of the firmware or operating system operating thereon.

A method and apparatus for host enumeration process. One embodiment of the method provides a bit to indicate to the host whether enumeration process should start or continue. The bit may be set when the shared resource process has been successfully completed, or the bit may be set if too much time has elapsed since the shared resource process has started, or the bit may be set if too much time has elapsed before the shared resource process is started, or the bit may be set if the shared resource process has not been performed successfully, or the bit may be set if the port is open and it is unnecessary to perform the shared resource process.
摘要:
A blade server system and method for virtually hot plugging and virtually hot removing functions in a shared I/O environment. A management node physically hot inserts and hot removes an I/O node in the server system without a compute node being aware of the hot insert and hot removal. The management node and the compute node create and remove virtual links between the compute node and the virtual functions.

A method includes providing a bridge device (105) connected to a host computing device (101-1, 101-2) and a peripheral device (103-1, 103-2, 103-N, 403-1, 403-2, 405-1, 405-2, 405-3), the bridge device (105) being configured to communicatively couple the host device (101-1, 101-2) to the peripheral device (103-1, 103-2, 103-N, 403-1, 403-2, 405-1, 405-2, 405-3); and preventing execution of a hardware enumeration process (313) in the host device (101-1, 101-2) until completion of a resource allocation process (303) in the bridge device (105).
摘要:
A system for transforming a single root input/output virtualization (SR-IOV) function to appear as a legacy function, and a corresponding method includes a switch platform coupled between a legacy host and a SR-IOV-enabled device. The switch platform includes a processor programmed to discern configuration cycles by type and to process the configuration cycles, and one or more local registers that store data related to the configuration cycles.

摘要:
There is provided a system and method of controlling transaction flow in a communications interface. An exemplary system comprises a first buffer configured to hold packets of a first packet type, and a second buffer configured to hold packets of a second packet type. An exemplary system also comprises a counter configured to track a delay-reference of packets held in the second buffer. An exemplary system also comprises a controller configured to receive packets from a host and send packets of the first packet type to the first buffer and to send packets of the second packet type to the second buffer, the controller being further configured to stop receiving packets if the delay-reference meets or exceeds a specified threshold.
