摘要： A resource and partition manager virtualizes interrupts without using any additional hardware in a way that does not disturb the interrupt processing model of operating systems running on a logical partition. In other words, the resource and partition manager supports virtual interrupts in a logically partitioned computer system that may include share processors with no changes to a logical partition's operating system. A set of virtual interrupt registers is created for each virtual processor in the system. The resource and partition manager uses the virtual interrupt registers to process interrupts for the corresponding virtual processor. In this manner, from the point of view of the operating system, the interrupt processing when the operating system is running in a logical partition that may contain shared processors and virtual interrupts is no different that the interrupt processing when the operating system is running in computer system that only contains dedicated processor partitions.

摘要： The present invention provides for storing and using a stored logical partition indicia in a TLB. A partition in a microprocessor architecture is employed. A virtual page number is selected. A stored LPID indicia corresponding to the selected page number is read from a TLB. The stored logical partition indicia from the TLB is compared to a logical partition indicia associated with the employed partition. If the stored logical partition indicia and the logical partition indicia associated with the employed partition match, a corresponding page table entry stored in the translation look-aside buffer is read. If they do not match, a page table entry from a page table entry source is retrieved and stored in the TLB. If a partition is to invalidate an entry in the TLB, a TLB entry command is generated and used to invalidate a memory entry.

摘要： A partition manager includes an I/O reconfiguration mechanism and a logical partition suspend/resume mechanism that work together to perform autonomic I/O reconfiguration in a logically partitioned computer system. When I/O reconfiguration is required, the affected logical partitions are suspended, the I/O is reconfigured, and the affected logical partitions are resumed. Because the logical partitions are suspended during I/O reconfiguration, any ghost packet that may occur when the I/O is reconfigured is ignored.
摘要翻译：分区管理器包括I / O重新配置机制和逻辑分区挂起/恢复机制，其协同工作以在逻辑分区的计算机系统中执行自主I / O重新配置。当需要I / O重新配置时，受影响的逻辑分区将被挂起，重新配置I / O，并恢复受影响的逻辑分区。因为逻辑分区在I / O重新配置期间被挂起，所以当I / O被重新配置时可能发生的任何ghost数据包被忽略。

摘要： Disclosed is a computer implemented method, computer program product, and apparatus to establish at least one paging partition in a data processing system. The virtualization control point (VCP) reserves up to the subset of physical memory for use in the shared memory pool. The VCP configures at least one logical partition as a shared memory partition. The VCP assigns a paging partition to the shared memory pool. The VCP determines whether a user requests a redundant assignment of the paging partition to the shared memory pool. The VCP assigns a redundant paging partition to the shared memory pool, responsive to a determination that the user requests a redundant assignment. The VCP assigns a paging device to the shared memory pool. The hypervisor may transmit at least one paging request to a virtual asynchronous services interface configured to support a paging device stream.

摘要： Techniques for simulating exclusive use of a processor core amongst multiple logical partitions (LPARs) include providing hardware thread-dependent status information in response to access requests by the LPARs that is reflective of exclusive use of the processor by the LPAR accessing the hardware thread-dependent information. The information returned in response to the access requests is transformed if the requestor is a program executing at a privilege level lower than the hypervisor privilege level, so that each logical partition views the processor as though it has exclusive use of the processor. The techniques may be implemented by a logical circuit block within the processor core that transforms the hardware thread-specific information to a logical representation of the hardware thread-specific information or the transformation may be performed by program instructions of an interrupt handler that traps access to the physical register containing the information.

摘要： An apparatus, system, and method are disclosed for improved support of MPS segments in a microprocessor. The virtual address is used to generate possible TLB index values for each of the supported page sizes of the MPS segment associated with the virtual address. The possible TLB index values may be a hash generated using the virtual address and one of the supported page sizes. The TLB is searched for actual TLB index values that match the possible TLB index values calculated using the different supported page sizes. TLB entries associated with those actual TLB index values are checked to determine whether any TLB entry is associated with the virtual address. If no match is found, the real address is retrieved from the PT. The actual page size in the PT is used to generate an actual TLB index value for the virtual address and the TLB entry is inserted into the TLB.

摘要： Multiple machine state registers are included in a processor core to permit distinction between use of hardware facilities by applications, supervisory threads and the hypervisor. All facilities are initially disabled by the hypervisor when a partition is initialized. When any access is made to a disabled facility, the hypervisor receives an indication of which facility was accessed and sets a corresponding hardware flag in the hypervisor's machine state register. When an application attempts to access a disabled facility, the supervisor managing the operating system image receives an indication of which facility was accessed and sets a corresponding hardware flag in the supervisor's machine state register. The multiple register implementation permits the supervisor to determine whether particular hardware facilities need to have their state saved when an application context swap occurs and the hypervisor can determine which hardware facilities need to have their state saved when a partition swap occurs.
