    摘要: A method, system and computer program product for providing filtering of level two guest (G2) quiesce requests. The method includes receiving a G2 quiesce interruption request at a processor currently or previously executing a G2 running under a level two hypervisor in a logical partition. The G2 includes a current zone and G2 virtual machine (VM) identifier. The quiesce interruption request specifies an initiating zone and an initiating G2 VM identifier. It is determined if the G2 quiesce interruption request can be filtered by the processor. The determining is responsive to the current G2 VM identifier, the current zone, the initiating zone and the initiating G2 VM identifier. The G2 quiesce interruption request is filtered at the processor in response to determining that the G2 quiesce interruption request can be filtered. Thus, filtering between G2 virtual machines running in the logical partition is provided.

    摘要: What is provided is an enhanced dynamic address translation facility. In one embodiment, a virtual address to be translated and an initial origin address of any one of a region first table, a region second table, a region third table, or a segment table are obtained. Based on the obtained initial origin address, a segment table entry is obtained which contains a format control and DAT protection fields. If the format control field is enabled, obtaining from the translation table entry a segment-frame absolute address of a large block of data in main storage. The segment-frame absolute address is combined with a page index portion and a byte index portion of the virtual address to form a translated address of the desired block of data. If the DAT protection field is not enabled, fetches and stores are permitted to the desired block of data addressed by the translated virtual address.

    摘要: What is provided is an enhanced dynamic address translation facility. In one embodiment, a virtual address to be translated and an initial origin address of a translation table of the hierarchy of translation tables are obtained. An index portion of the virtual address is used to reference an entry in the translation table. If a format control field contained in the translation table entry is enabled, the table entry contains a frame address of a large block of data of at least 1M byte in size. The frame address is then combined with an offset portion of the virtual address to form the translated address of a small 4K byte block of data in main storage or memory.

    摘要: What is provided is an enhanced dynamic address translation facility. In one embodiment, a virtual address to be translated is first obtained and an initial origin address of a translation table of the hierarchy of translation tables is obtained. Based on the obtained initial origin, a segment table entry is obtained. The segment table entry is configured to contain a format control and access validity fields. If the format control and access validity fields are enabled, the segment table entry further contains an access control field, a fetch protection field, and a segment-frame absolute address. Store operations are permitted only if the access control field matches a program access key provided by any one of a Program Status Word or an operand of a program instruction being executed. Fetch operations are permitted if the program access key associated with the virtual address is equal to the segment access control field.

    摘要: What is provided is an enhanced dynamic address translation facility. In one embodiment, a virtual address to be translated and an initial origin address of a translation table of the hierarchy of translation tables are obtained. A segment table entry obtained from a segment table contains a format control field. If the format control field is enabled, a segment-frame absolute address of a large block of data in main storage is obtained from the segment table entry. Each 4K byte block of data within the large block has an associated storage key. Store operations associated with the virtual address are performed to the desired block of data. If the change recording override field is disabled, the change bit of the storage key associated with the desired 4K byte block is set to 1. An indication is then provided that the desired 4K byte block has been modified.
