NAME : HCPAMTE DESCRIPTION: ASIT Management Table Entry for PTRM i-ASITs DSECT : AMTE FUNCTION : There is one ASIT Management Entry for each PTRM address space. The ASIT Management Table resides in HCPRSM and consists of 16 doubleword table entries. The ASIT Management Table contains entries that are either marked invalid or contain the i-ASIT for a PTRM address space. LOCATED BY : RSAASITB - ASIT table for the PRM address spaces RSAASITB + (Address space index * AMTLENTH) AMTNEXT - the next contiguous AMTE CREATED BY : All AMTEs are contained in HCPRSM. Each entry is initialized as invalid by HCPPRMIN. DELETED BY : none SERIALIZED : RSAAFLK - PTRM i-ASIT Resolution Lock COMMENTS : none
