摘要： Methods, systems, and computer program products are provided for scheduling threads in a multiprocessor computer. Embodiments include selecting a thread in a ready queue to be dispatched to a processor and determining whether an interrupt mask flag is set in a thread control block associated with the thread. If the interrupt mask flag is set in the thread control block associated with the thread, embodiments typically include selecting a processor, setting a current processor priority register of the selected processor to least favored, and dispatching the thread from the ready queue to the selected processor. In some embodiments, setting the current processor priority register of the selected processor to least favored is carried out by storing a value associated with the highest interrupt priority in the current processor priority register.

摘要： An improved method in a data processing system for forwarding network file system requests and responses between network segments. A notice is received that data has arrived at a receive buffer for a socket. The receive buffer is connected for the socket and a send buffer for another socket to form a splice. Both the socket and the other socket are flagged as a spliced connection.

摘要： The present invention provides a system, method, and computer program product that enables application instances to pass block mode storage requests directly to a physical I/O adapter without run-time involvement from the local operating system or hypervisor. Specifically, a mechanism for providing and using a linear block address (LBA) translation protection table (TPT) to control out of user space I/O operations is provided. In one aspect of the present invention, the LBATPT includes an adapter protection table that has entries for each portion of a storage device. Entries include access control values which identify whether the entry is valid and what access type operations may be performed on a corresponding portion of a storage device. I/O requests may be checked against these access control values to determine if an application instance that submitted the I/O requests may access the LBAs identified in the I/O requests in the manner requested.

摘要： A system, method, and computer program product that enables user space middleware or applications to pass file name based storage requests directly to a physical I/O Adapter without run-time involvement from the local Operating System (OS) are provided. A mechanism is provided for using a file protection table (FPT) data structure, which may include a file name protection table (FNPT) and file extension protection table (FEPT), to control user space and out of user space Input/Output (I/O) operations. The FNPT has an entry for each file managed by the OS′ file system and points to a segment of the FEPT. Each entry in the FEPT may include a protection domain, along with other protection table context information, against which I/O requests may be checked to determine if an application instance that submitted the I/O requests may access the file identified in the I/O requests.

摘要： The present invention provides a system, method, and computer program product that enables application instances to pass block mode storage requests directly to a physical I/O adapter without run-time involvement from the local operating system or hypervisor. In one aspect of the present invention, a mechanism is provided for determining whether a user space operation is a resource management operation of a work processing operation. If the user space operation is a resource management operation, appropriate functions are performed to either query, create, modify or destroy resource allocations in the I/O adapter. If the user space operation is a work processing operation, appropriate functions are performed to either create work queue entries and inform the I/O adapter of the work queue entries or to retrieve completion queue entries for work queue entries whose processing has been completed by the I/O adapter.

摘要： The present invention provides a system, method, and computer program product that enables user space middleware or applications to pass block mode storage requests directly to a physical I/O Adapter without run-time involvement from the local Operating System (OS), or, in a virtual system, the local Hypervisor. Specifically, the present invention is directed to a mechanism for providing and using a linear block address (LBA) translation protection table (TPT) to control user space and out of user space Input/Output (I/O) operations. In one aspect of the present invention, the LBATPT includes an adapter protection table that has entries for each portion of a storage device. Each entry may include a key instance and protection domain, along with other protection table context information, against which I/O requests may be checked to determine if an application instance that submitted the I/O requests may access the LBAs identified in the I/O requests.
