摘要： Dynamic control of memory affinity is provided for a shared memory logical partition within a shared memory partition data processing system having a plurality of nodes. The memory affinity control approach includes: determining one or more home node assignments for the shared memory logical partition, with each assigned home node being one node of the plurality of nodes of the system; determining a desired physical page level per node for the shared memory logical partition; and allowing the shared memory partition to run and using the home node assignment(s) and its desired physical page level(s) in the dispatching of tasks to physical processors in the nodes and in hypervisor page memory management to dynamically control memory affinity of the shared memory logical partition in the data processing system.

摘要： Transparent hypervisor pinning of critical memory areas is provided for a shared memory partition data processing system. The transparent hypervisor pinning includes receiving at a hypervisor a hypervisor call initiated by a logical partition to register a logical memory area of the logical partition with the hypervisor. Responsive to this hypervisor call, the hypervisor transparently determines whether the logical memory is a critical memory area for access by the hypervisor. If the logical memory area is a critical memory area, then the hypervisor automatically pins the logical memory area to physical memory of the shared memory partition data processing system, thereby ensuring that the memory area will not be paged-out from physical memory to external storage, and thus ensuring availability of the logic memory area to the hypervisor.

摘要： Hypervisor managed memory paging is provided in a data processing system having multiple logical partitions. The data processing system includes a shared memory pool defined within physical memory. The shared memory pool includes a volume of physical memory with dynamically adjustable sub-volumes or sets of physical pages associated with the multiple logical partitions. Each sub-volume or set is associated with a particular logical partition and includes mapped logical memory pages for that logical partition. A hypervisor memory manager interfaces the multiple logical partitions and the shared memory pool, and manages access to logical memory pages within the shared memory pool. The hypervisor memory manager further manages page-out and page-in of logical memory pages from the shared memory pool to one or more external paging devices. This page-out and page-in managing by the hypervisor memory manager is transparent to the multiple logical partitions.

摘要： Relocating data in a virtualized environment maintained by a hypervisor administering access to memory with a Cache Page Table (‘CPT’) and a Physical Page Table (‘PPT’), the CPT and PPT including virtual to physical mappings. Relocating data includes converting the virtual to physical mappings of the CPT to virtual to logical mappings; establishing a Logical Memory Block (‘LMB’) relocation tracker that includes logical addresses of an LMB, source physical addresses of the LMB, target physical addresses of the LMB, a translation block indicator for each relocation granule, and a pin count associated with each relocation granule; establishing a PPT entry tracker including PPT entries corresponding to the LMB to be relocated; relocating the LMB in a number of relocation granules including blocking translations to the relocation granules during relocation; and removing the logical addresses from the LMB relocation tracker.

摘要： Operating system-directed workload scheduling of an adjunct partition in a logically partitioned computer is selectively overridden to handle platform work requiring a Quality of Service (QoS) guarantee. Firmware may track outstanding requests for platform work for an adjunct partition, and in response to a request for platform work that requires a QoS guarantee, the firmware may assume or take over scheduling decisions for the adjunct partition from the operating system of an associated logical partition and schedule execution of the adjunct partition to ensure that the adjunct partition will be allocated sufficient execution resources to perform the platform work independent of the scheduling desires of the operating system. As a result, any platform work that potentially impacts the platform work of other adjunct partitions will not be held up as a result of an unwillingness or inability of the operating system to schedule execution of the adjunct partition.
