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
