摘要： A mechanism for initializing shared memories for sharing endpoints across a plurality of root complexes is provided. A multi-root PCIe manager (MR-PCIM) initializes the shared memory between root complexes and endpoints by discovering the PCIe switch fabric by traversing all the links accessible through the interconnected switches of the PCIe switch fabric. As the links are traversed, the MR-PCIM compares information obtained for each of the root complexes and endpoints to determine which endpoints and root complexes reside on the same blade. A virtual PCIe tree data structure is then generated that ties the endpoints available on the PCIe switch fabric to each root complex. The MR-PCIM, or a single-root PCIe manager (SR-PCIM), may then assign each endpoint and root complex a base and limit within the PCIe memory address space the endpoint belongs to.

摘要： A method mechanism is provided for communication between host systems using a transaction protocol and shared memories. Shared memories are initialized based on a discovery process in a communication fabric such that at least one endpoint has address ranges in shared memories of at least two host systems. A transaction oriented protocol may be established for using the shared memories of the host systems to communicate between root complexes and endpoints of the same or different host systems. The transaction oriented protocol specifies a series of transactions to be performed by the various elements, e.g., root complex or endpoint, to push or pull data. Various combinations of push and pull transactions may be utilized.

摘要： A system and method for migration of a virtual endpoint from one virtual plane to another are provided. With the system and method, when a management application requests migration of a virtual endpoint (VE) from one virtual plane (VP) to another, a fabric manager provides an input/output virtualization intermediary (IOVI) with an interrupt to perform a stateless migration. The IOVI quiesces outstanding requests to the virtual functions (VFs) of the VE, causes a function level reset of the VFs, deconfigures addresses in intermediary switches corresponding to the VP, and informs the fabric manager that a destination migration is requested. The fabric manager sends an interrupt to the destination IOVI which performs a function level reset of the destination VFs and reprograms the intermediary switches with the addresses of the destination VP. The destination VFs may then be placed in an active state.

摘要： A system and method for migration of stateless virtual functions from one virtual plane to another are provided. When a migration of a source virtual function to a destination virtual function in another virtual plane is to be performed, a source single root PCI manager (SR-PCIM) is first interrupted by a multiple root PCI manager (MR-PCIM). Configuration information that defines the source virtual function is then redefined on the destination virtual function for this stateless migration. A function level reset may then be performed on the source virtual function. The destination SR-PCIM may be interrupted by the MR-PCIM with an interrupt for the destination virtual function. A function level reset may then be performed on the destination virtual function. The destination virtual function state may then be changed to an “active” state such that the migrated virtual function begins processing transactions.

摘要： A system and method for hot-plug/remove of a new component in a running communication fabric, such as a PCIe fabric, are provided. With the system and method, the addition of a new component in the fabric is detected and an event is sent to a multiple root fabric configuration manager. The multiple root fabric configuration manager gathers information about the new component and updates its I/O component tree structure in its configuration data structure to include the new component. The new component may then be utilized via the updated configuration data structure. When a component is to be removed, the multiple root fabric configuration manager receives an event indicating the component to be removed, determines which branches of the tree structure are affected by the removal, and updates its configuration data structure accordingly to remove the component and its associated components from the virtual plane of the removed component.

摘要： A system and method for communication between host systems using a socket connection and shared memories are provided. With such socket-based communication, a work queue in the host systems may be used to listen for incoming socket initialization requests. A first host system that wishes to establish a socket communication connection with a second host system may generate a socket initialization request work queue element in its work queue and may inform the second host system that the socket initialization request work queue element is available for processing. The second host system may then accept or deny the request. If the second host system accepts the request, it returns the second half of the socket's parameters for use by the first host system in performing socket based communications between the first and second host systems.

摘要： A mechanism is provided for communication between host systems using a queuing system and shared memories. Memory address spaces of the host systems are initialized such that endpoints may be accessible by root complexes across host systems. These memory address spaces may then be used to allow system images, and their corresponding applications, associated with these root complexes to communicate with the endpoints using a queuing system. Such a queuing system may comprise queue structures having doorbell structures for providing information about the queue entries in the queue structures. Queue elements may be generated and added to the queue structures, and the doorbell structure may be written to, in order to thereby inform an endpoint or root complex that queue elements are available for processing. DMA operations may be performed to retrieve the queue elements and the data corresponding to the queue elements.
