摘要： A method and system for selecting the architecture level to which a processor appears to conform within a computing environment when executing specific logical partitions or programs and performing migration among different levels of processor architecture. The method utilizes a “processor compatibility register” (PCR) that controls the level of the architecture that the processor appears to support. In one embodiment, the PCR is accessible only to super-privileged software. The super-privileged software sets bits in the PCR that specify the architecture level that the processor is to appear to support so that when the program runs on the processor, the processor behaves in accordance with the architecture level for which the program was designed.

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.

摘要： A computer system has a cache located between input/output devices and a main system memory. All system memory accesses by the input/output devices are made through the cache. Memory accesses through the cache are limited to those addresses which are accessible to a central processor and input/output devices. All access to such addresses by the central processor are made through the cache.

摘要： A method for use in a virtual memory data processing system employing a pageable External Page Table data structure for recording current status and disk address information for each virtual page in said system, provides improved system performance when a large number of virtual pages are to be operated on in the same manner. In accordance with the method, each page of External Page Table entries can record a predetermined number of entries (512), depending on the byte capacity of each virtual page (2,048) and the size of each entry (4 bytes). One page of 512 entries correspond to 1 megabyte of virtual storage (512.times.2,048) and also appears as one entry in a pinned External Page Table. The pinned External Page Table is referred to as the "XPT of the XPT," and has the same format as the pageable XPT. A 256 megabyte segment of virtual memory is representable in the XPT of the XPT by 256, 4 byte entries, or one-half of a page.Where all virtual pages represented by a page of XPT entries are to be processed in the same way (i.e., created, destroyed), one operation on one entry in the XPT of the XPT is made, rather than 512 operations on the 512 entries of the XPT.

摘要： A method to logically serialize a plurality of independent system events in a virtual memory data processing system. Each event causes interrupt servicing routines to be executed and requires data structures that record the status of virtual pages to be updated. The system events include the interrupt that is generated as a result of a page fault, the interrupt that is generated as a result of a paging I/O completion operation that resolves a page fault, and lastly interrupts generated in response to a supervisory call to a paging service.

摘要： A mechanism is added to a 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. 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.
