NAME : HCPFPRBK DESCRIPTION: Floating-Point Register Block DSECT : FPRBK FUNCTION : Maps the block that holds guest floating-point registers. LOCATED BY : VMDFPVRB field in the VMDBK CREATED BY : HCPBVM for non-vSIE VMDBKs. DELETED BY : HCPUSP at logoff time HCPGIR when the FPRBK is replaced with a VECBK. SERIALIZED : I-stream RELOCATION CONSIDERATIONS : This control block is relocated as part of a live guest relocation (LGR). The bits and fields that need to be relocated are defined in the $VMDFPRS field of the LGRVMDBK. Whenever changes are made to this control block, consideration must be given to any effects these changes will have on a relocation. If any new fields or bits are defined, they may need to be relocated. If existing bits or fields are changed, corresponding modifications may be required in the LGR version of this control block. Consider also the effects of these changes on a relocation involving a back-level release of CP. |
