NAME : HCPCCFBK
DESCRIPTION: CPU-Measurement Counter Facility Counters
DSECT : CCFBK
FUNCTION : Mapping of the CPU-Measurement Facility Counters
for all supported Counter First Version Number (CFVN)
and Counter Second Version Number (CSVN) combinations.
LOCATED BY : PLSCCFBK
CREATED BY : HCPMPS (when a PLSBK is allocated)
DELETED BY : HCPMPS (when a PLSBK is released)
REFERENCES : none
SERIALIZED : Processor Local - updates are only made on the CPU
whose PLSBK points to this instance of the CCFBK.
Monitor Command Lock (MND_CMD_LOCK) - the collection
task is serialized by this lock to prevent a race
between two tasks collecting counters in the CCFBK
on each CPU.
RELOCATION CONSIDERATIONS : None
COMPATIBILITY AND MIGRATION CONCERNS : The format of this control block is defined in "The
Set-Program-Parameter and CPU-Measurement Facilities"
book and should not be modified. If new CFVN/CSVN
combinations are created, new mappings will need
to be added to support them.
