摘要： A method of managing memory mapped input output operations to an alternate address space comprising: executing a first instruction directed to a first memory mapped input output alternate address space of a machine associated with a first adapter to allocate a resource associated with the first adapter to a process in accordance with a definition of a z/Architecture; wherein a selected process issues at least one of a load and a store instruction executed in a problem state of the machine to a selected address location of a selected resource. The method further includes ensuring that the selected resource corresponds with the allocated resource and determining that the selected process corresponds with the process to which the resource is allocated.

摘要： A method, system, and computer-usable medium for supporting debugging of host channel adapters in a logical partitioning environment. In a preferred embodiment of the present invention, a hypervisor acquires control of a trace facility and sets trace parameters for the host channel adapter. In response to determining a trace event that matches said trace parameter has been triggered, the hypervisor retrieves trace information from a buffer. In response to determining the buffer does not include any more trace information, the hypervisor determines if modification of the trace parameters is required. If the modification of the trace parameters is required, the hypervisor alters the trace parameters in anticipation of another trace event.

摘要： A method for providing a message-time-ordering facility is disclosed. The method comprises initiating the message-timer ordering facility for a message at a sender system. Initiating includes setting a delay variable to zero. The message is sent to a receiver system in response to initiating the message-time-ordering facility. Sending the message includes marking the message with a first departure time-stamp responsive to a sender system clock and transmitting the message to the receiver system. The message is received at the at the receiver system, receiving includes delaying the processing of the message until the time on a receiver system clock is greater than the first departure time-stamp and recording a time associated with the delaying the processing of the message in the delay variable. A response to the message is sent to the sender system in response to receiving the message. Sending the response includes marking the response with a second departure time-stamp responsive to the receiver system clock if the delay variable is equal to zero and transmitting the response to the sender system. The response is received at the sender system. Receiving the response includes delaying the processing of the response if the delay variable is equal to zero until the time on the sender system clock is greater than the second departure time-stamp and recording a time associated with the delaying the processing of the response in the delay variable.

摘要： Controlled partition shut-down is provided within a shared memory partition data processing system including a shared memory partition, a paging service partition, a hypervisor and a shared memory pool within physical memory. The hypervisor manages access to logical pages within the pool and page-out of pages from the pool to external paging storage via the paging service partition. A respective paging service stream exists between the paging service partition and hypervisor for each shared memory partition, with each stream including a stream state. The control method includes: responsive to a shut-down initiating event, notifying the paging service partition to shut down, and determining whether a shared memory partition is currently active, and if so, signaling the hypervisor to complete paging activity for the active memory partition and waiting for its stream state to enter a suspended or a completed state before automatically shutting down the paging service partition.

摘要： Firmware of an InfiniBand (IB) host computer device provides a representation of an IB Host Channel Adapter (HCA) within the hierarchical data structure during system initialization. An ib-boot support package encapsulates arguments for booting over an IB network using an ibport device. The ib-boot support package supports use of one or more command keywords, each identifying a specific type of support package utilized to retrieve the boot image. When the srp keyword is provided, an SRP protocol is used to access the storage boot device and retrieve the boot file. Access to the boot server is thus provided via one of the support packages, and the boot image is returned to the host device via the IB network for completion of boot operations.

摘要： An on-demand allocation of virtual asynchronous services interface adapters is provided. A determination is made as to whether an operation request requires that a set of virtual I/O service partitions have a required number of virtual asynchronous services interface adapters. If a required number of virtual asynchronous services interface adapters is required, a determination is made as to whether the set of virtual I/O service partitions have the required number of virtual asynchronous services interface adapters. Responsive to a failure to have the required number of virtual asynchronous services interface adapters, a set of new virtual asynchronous services interface adapters is defined in partition management firmware and in the set of virtual I/O service partitions. The set of new virtual asynchronous services interface adapters is configured in the set of virtual I/O service partitions and the operation is issued to the set of virtual I/O service partitions.
