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 keywords identifying a network support package or a Sockets Direct Protocol (SDP) support package. When the first keyword is provided, the IPoIB network protocol is used to access the boot server and retrieve the boot file. When the second keyword is provided, the IB network boot method is implemented, whereby the SDP network protocol is used to access the boot device. 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： A method of performing memory mapped input output operations to an alternate address space comprising: establishing a first instruction directed to a first memory mapped input output alternate address space associated with an adapter to store data in accordance with a definition of a z/Architecture; establishing a second instruction directed to the first memory mapped input output alternate address space associated with an adapter to load data in accordance with a definition of a z/Architecture; allocating at least one of a real resource and a virtual resource associated with the first alternate address space to a process; ensuring that the selected process corresponds with the process to which the resource is allocated. The process issues at least one of the first instruction and the second instruction and thereby causes execution of at least one of the store and load with the first alternate address space.

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： Extending the network support package to accept network addresses in IPv6 format and allow the use of other boot discovery protocols, such as DHCP, to acquire the information needed to boot a system using a file on a remote server. A mechanism is added to the network support package to enable/allow the specification of additional boot discovery protocols and additional network address formats. The mechanism defines qualifier keywords that are added to the boot arguments and processed by the network support package. The qualifier keywords modify the boot arguments associated with a bootstrap method by specifying a way to acquire the arguments (i.e., a specific boot discovery protocol), the format of the arguments, and other parameters associated with the arguments. Qualifier keywords are optionally appended before the arguments. Multiple qualifier keywords may be added to the boot arguments at a time, and the keywords can be applied in their order within the arguments.

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： In response to a hypervisor page fault for memory that is not resident in a shared memory pool, an I/O paging request is sent to an external storage paging space. In response to a paging service partition encountering an I/O paging error, a paging failure indication is sent to the hypervisor. A simulated machine check interrupt instruction is sent from the hypervisor to the shared memory partition and a machine check handler obtains control. The machine check handler performs data analysis utilizing an error log in an attempt to isolate the I/O paging error to a process or a set of processes in the shared memory partition. The process or set of processes associated with the I/O paging error, or the shared memory partition itself, may be terminated. Finally, the shared memory partition may clear or initialize the page associated with the I/O paging error.
