AFFBK Prolog
NAME : HCPAFFBK DESCRIPTION: AFFinity management control BlocK DSECT : AFFBK FUNCTION : The AFFBK maps the storage in HCPRCC starting at label HCPRCCAF, extending for the length of this block. When the AFFBK is copied via the 'COPY' psuedo-op into any module other than HCPRCC, it will generate a DSECT. When copied in HCPRCC, however, it will generate code to actually define the fields. The AFFBK is used by the processor feature affinity management routines as an area to do bookkeeping and recording. LOCATED BY : HCPRCCAF is the address of the start of the block. CREATED BY : The block is DCed in module HCPRCC. DELETED BY : Never deleted SERIALIZED : Alterations and references to the AFFBK are serialized by the Scheduler Lock. RELOCATION CONSIDERATIONS : None
