摘要： A system for managing input/output drawers within a data processing system. A unique identifier is assigned to each of a plurality of drawers, and is used by the operating system to identify the drawers in the system regardless of how these drawers are interconnected. Another unique PCI-bridge identifier is assigned to each of a plurality of PCI Host bridges (PHBs) from all drawers, and is used by the operating system to perform input/output processes to devices associated with the plurality of PHBs such that the ODM object for each of the PHBs remains the same regardless of how the drawer is interconnected in the system. When a new drawer is added to the system, a new unique identifier is assigned to the new drawer ensuring that the unique identifiers previously assigned to the other drawers are not used to identify the new drawer.

摘要： A method, system, and apparatus for preventing input/output (I/O) adapters used by an operating system (OS) image, in a logically partitioned data processing system, from fetching or corrupting data from a memory location allocated to another OS image within the data processing system is provided. A hypervisor prevents transmission of data between an input/output adapter in one of the logical partitions and memory locations assigned to other logical partitions during a direct memory access (DMA) operation by assigning each of the input/output adapters a range of I/O bus DMA addresses. The I/O adapters (IOAs) are connected to PCI host bridges via terminal bridges. A single terminal bridge may support multiple IOAs, in which case every terminal bridge has a plurality of sets of range registers, each associated with a respective one of the IOAs to which it is connected. An arbiter is provided which selects one of the input/output adapters to use the PCI bus. The terminal bridge can examine the grant signals from the arbiter to the IOAs, to determine which set of range registers is to be used.

摘要： A method, system, and apparatus for isolating an input/output (I/O) bus error, received from an I/O adapter, from the other I/O adapters that may be in different partitions within a logically partitioned data process system is provided. In one embodiment, the logically partitioned data processing system includes a system bus, a processing unit, a memory unit, a host bridge, a plurality of terminal bridges, and a plurality of input/output adapters. The processing unit, memory unit, and the host bridge are all coupled to each other through the system bus. Each of the plurality of terminal bridges is coupled to the host bridge through a first bus. Each of the input/output adapters is coupled to one of the plurality of terminal bridges through a one of a plurality of second buses, such that each input/output adapter corresponds to a single terminal bridge. Each of the input/output adapters are assigned to one of a plurality of logical partitions within the data processing system. Each of the terminal bridges isolates errors received from a respective one of the input/output adapters from other input/output adapters, some of which may be within a different one of the plurality of logical partitions.

摘要： A processor recognizes a request from a program executing on a first hardware thread to initiate software code on a second hardware thread. In response, the second hardware thread initiates and commences executing the software code. During execution, the software code uses hardware registers of the second hardware thread to store data. Upon termination of the software code, the second hardware thread invokes a hypervisor program, which extracts data from the hardware registers and stores the extracted data in a shared memory area. In turn, a debug routine executes and retrieves the extracted data from the shared memory area.

摘要： A mechanism is provided in a logically partitioned data processing system for controlling depth and latency of exit of a virtual processor's idle state. A virtualization layer generates a cede latency setting information (CLSI) data. Responsive to booting a logical partition, the virtualization layer communicates the CLSI data to an operating system (OS) of the logical partition. The OS determines, based on the CLSI data, a particular idle state of a virtual processor under a control of the OS. Responsive to the OS calling the virtualization layer, the OS communicates the particular idle state of the virtual processor to the virtualization layer for assigning the particular idle state and wake-up characteristics to the virtual processor.

摘要： A method, apparatus, and computer program product are disclosed in a shared processor data processing system for coordinating error reporting for and resetting of a physical I/O adapter that supports virtualization. The physical I/O adapter is virtualized by generating virtual I/O adapters that each represent a portion of the physical I/O adapter. Each one of the virtual I/O adapters is assigned to a different one of client logical partitions. A determination is made regarding whether the physical I/O adapter may have experienced an error. If the physical I/O adapter has experienced an error, all of the client logical partitions are notified about the error and a recovery of the physical I/O adapter is coordinated among all of the client logical partitions by waiting for each client logical partition to acknowledge the error notification before the physical I/O adapter is reset.

摘要： A logically partitioned data processing system in which shared resources are emulated to provide each partition a separate copy of the shared resource is provided. In one embodiment, the logically partitioned data processing system includes a plurality of logical partitions, a plurality of operating systems executing within the data processing system and a plurality of assignable resources. Each of the plurality of operating systems is assigned to a separate one of the plurality of logical partitions, such that no more than one operating system is assigned to any given logical partition. Each of the plurality of assignable resources is assigned to a single one of the plurality of logical partitions. The logically partitioned data processing system also includes a hypervisor. The hypervisor emulates shared resources, such as an operator panel and a system console, and provides a virtual copy of these shared resources to each of the plurality of logical partitions.

摘要： An enhanced migration descriptor migrates a plurality of source sub-pages in a large source page accessible by direct memory access devices. A splitter and selector are integrated into a configuration of a computer. Responsive to a request to migrate a large page containing the plurality of source sub-pages in the source page, the splitter divides a plurality of high order page numbers from a plurality of low order page numbers. The selector selects the high order page number of the large page and creates an enhanced migration descriptor comprising the high order page number and a size of the large page. The selector, by the enhanced migration descriptor, combines the low order page number for a sub-page with the destination address and size of the enhanced migration descriptor to migrate the large page and each of the plurality of sub-pages.
