摘要： An aliased queue pair is provided within a logically partitioned data processing system for each logical partition for the single general services management queue pair that exists within a physical host channel adapter. Packets intended for the logical ports are received at the physical port. Multiple partitions exist within the data processing system. When one of these partitions needs to use one of the logical ports, a queue pair is selected. The queue pair is then associated with the logical port. The queue pair is configured as an aliased general services management queue pair and is used by the partition as if the aliased queue pair were the single general services management queue pair provided in the channel adapter.

摘要： A method and system are disclosed for logically partitioning resources of a single channel adapter for use in a system area network. Each resource includes a partition identifier register within which is stored a partition identifier. A first one of the resources is assigned to a first partition by storing a first partition identifier in the partition identifier register within the first one of the resources. A second one of the resources is assigned to a second partition by storing a second partition identifier in the partition identifier register within the second one of the resources. Partitioning of the resources is enforced by permitting access to the first resource by only the first partition and permitting access to the second resource by only the second partition by checking the partition identifiers of each resource.

摘要： An apparatus, system and method for providing multiple logical partitions in a system area network are provided Logical partitioning support is provided for host channel adapters which allows multiple operating systems to share the resources of a single physical host channel adapter (HCA). The apparatus, system and method ensures that each operating system is unaware that the HCA hardware resources are being shared with other operating systems and further guarantees that the individual operating systems are prevented from accessing HCA hardware resources which are associated with other operating systems.

摘要： A method, apparatus, and computer program product are disclosed in a data processing system for migrating data pages subject to DMA access by temporarily disabling selected DMA operations within a physical I/O adapter. A determination is made as to whether to disable data access DMA capabilities of the physical I/O adapter. An operating mode of the physical I/O adapter is set to a particular mode utilizing a mode bit according to the determination of whether to disable data access DMA capabilities. Only data access DMA capabilities of the physical I/O adapter are disabled when the mode bit is set. Administrative services operations continue to be performed by the physical I/O adapter when the data access DMA capabilities of the physical I/O adapter are disabled.

摘要： An apparatus, system and method for controlling access to facilities based on usage class of a requestor are provided. With the apparatus, system and method, a two level protection mechanism is provided for protecting host channel adapter (HCA) facilities from unauthorized access. With the present invention, a first level of access is provided through virtual address translation and a mechanism for determining if the requestor of access may access a system memory address space page associated with a real address to which the virtual address maps. A second level of access is provided through the allocation of usage classes and determining a required usage class for accessing an HCA facility.

摘要： A mechanism is provided for sharing resources among logical partitions in a logical partitioned data processing system and for managing the changes to resources in such a way that the sharing operating systems are able to handle the various transitions in a graceful manner. Four hypervisor functions plus a specific return code manage the granting of access of resources owned by one partition to another (client) partition, accepting of granted resources by client partitions, returning of granted resources by client partitions, and rescinding of access by the owning partition. These four hypervisor functions are invoked either explicitly by the owning and client partitions or automatically by the hypervisor in response to partition termination. The hypervisor functions provide the needed infrastructure to manage the sharing of logical resources among partitions.

摘要： A computer implemented method, apparatus and mechanism for recovery of an I/O fabric that has become terminally congested or deadlocked due to a failure which causes buffers/queues to fill and thereby causes the root complexes to lose access to their I/O subsystems. Upon detection of a terminally congested or deadlocked transmit queue, access to such queue by other root complexes is suspended while each item in the queue is examined and processed accordingly. Store requests and DMA read reply packets in the queue are discarded, and load requests in the queue are processed by returning a special completion package. Access to the queue by the root complexes is then resumed.
