An RST entry contains an RTT designation. An RTT entry contains a segment-table designation. The format of a region-table entry is architected, and described in the Principles of Operation. LOCATED BY : CR1 is the ASCE for the primary address space. CR7 is the ASCE for the secondary address space. CR13 is the ASCE for the home address space. VMDPASCE is the ASCE for the primary address space. ASTASCE CREATED BY : HCPASMCR when an address space equal to or greater than 2 gigabytes is created. DELETED BY : HCPASMDS when the address space is destroyed. RELOCATION CONSIDERATIONS : None |
