NAME : HCPSALBK
DESCRIPTION: Slot Allocation Data Block
DSECT : SALBK
FUNCTION : Maps the data in the slot allocation data areas
in HCPPGD for paging (HCPPGDPG) and spooling
(HCPPGDSP).
LOCATED BY : The data areas mapped by this block,
HCPPGDPG (paging data) and HCPPGDSP (spooling
data), are in nucleus-resident areas.
CREATED BY : The data areas mapped by this block are created
at system generation.
DELETED BY : The data areas mapped by this block are
never deleted.
SERIALIZED : SALLOCK unless otherwise noted.
RELOCATION CONSIDERATIONS : None
COMMENTS : There are two flag bytes in the SALBK,
SALFLGCF & SALFLG90, to control warning messages for
the allocation type.
Each byte has a bit for each category of warning message
SALMSGFU = 100% full
SALMSGA9 = A configured percent between 91-99% full
SALMSG90 = 90% full
SALMSGB9 = A configured percent between 0-89% full
SALFLGCF indicates the messages that are enabled ('0'B)
and disabled ('1'B), taking into account configuration
options.
In the SALBK for paging space:
SALMSGFU = 0, always enabled
SALMSGA9 = 1, disabled by default
= 0, enabled when the configured PAGING
WARNING value is between 91-99%
SALMSG90 = 0, always enabled
SALMSGB9 = 1, disabled by default
= 0, enabled when the configured PAGING
WARNING value is between 0-89%
In the SALBK for spool space:
SALMSGFU = 0, always enabled
SALMSGA9 = 1, always disabled
SALMSG90 = 0, always enabled
SALMSGB9 = 1, always disabled
SALFLG90 is initialized from SALFLGCF and is updated to
reflect the messages that have been issued. When a
bit is '1'B in SALFLG90, the corresponding message is
either disabled or has been issued.
