STFLE DSECT
Cross Reference (Contains links to field and bit definitions)
STFLE Prolog
NAME : HCPSTFLE
DESCRIPTION: STFLE response mapping
DSECT : STFLE
FUNCTION : Map STFLE response in HCPRCCFL
LOCATED BY : HCPRCCFL
CREATED BY : not a control block, just a DSECT, so not created
DELETED BY : see above
REFERENCES : none
SERIALIZED : N/A
COMPATIBILITY AND MIGRATION CONCERNS : N/A
NOTES : This DSECT is used to map the data from the
STFLE instruction that is issued during system
initialization.
Note that the first four bytes of output from
both the STFL and STFLE instructions are the
same and are stored at location PFXSTFL. The
bytes defined at PFXSTFL are used to address
these four bytes from both instructions.
This DSECT is the method to address STFLE
bytes 4 and up, and may also be used to address
STFLE bytes 0 through 3. The bit definitions
in HCPEQUAT are used with both this DSECT and
PFXSTFL to address individual bits.

If this bit is off, IDTE simply purges all TLBs. If this bit is on, STFL0IDT is also on. .... .1..

"Selectively" means the TLB purging is limited to those specific entries required by architecture. If this bit is off, IDTE Invalidation-and-Clearing of RTE(s) simply purges all TLBs.
