0010 16 Signed 4 QSBEQBVM EQBS Executed by z/VM
EQBS Partially Executed by z/VM (QSBEQBPV)

complete.
0014 20 Signed 4 QSBEQBPV EQBS Partially Executed by z/VM
PEI Code (01) QSD Lock Failure Counter (QSBLOCK)
The number of times the QIOBK/QSD Lock could not be
acquired by CP Millicode in an acceptable time frame
during the interpretive execution of a QEBSM instruction.
0018 24 Signed 4 QSBLOCK QIOBK/QSD Lock Failure
PEI Code (02) Guest SL Access Exception (QSBGSL)
The number of times CP Millicode encounters an access
exception during the interpretive execution of a QEBSM
instruction referencing a guest's SL.
001C 28 Signed 4 QSBGSL Guest SL Access Exception
PEI Code (03) Guest SBAL Access Exception (QSBGSBAL)
The number of times CP Millicode encounters an access
exception during the interpretive execution of a QEBSM
instruction referencing a guest's SBAL.
0020 32 Signed 4 QSBGSBAL Guest SBAL Access Exception
PEI Code (04) Guest SB Access Exception (QSBGSB)
The number of times CP Millicode encounters an access
exception during the interpretive execution of a QEBSM
instruction referencing a guest's SB.
0024 36 Signed 4 QSBGSB Guest SB Access Exception
PEI Code (07) FOBLK/FOB Resource Exhaustion (QSBPP07)
The number of times CP Millicode found the available-FOB
list for the running CPU was empty.
0028 40 Signed 4 QSBFOBX FOBLK/FOB Resource Exhaustion
PEI Code (11) QSD Output Lock Failure Counter (QSBOLCK)
The number of times the QIOBK/QSD Lock could not be
acquired by CP Millicode in an acceptable time frame
during the interpretive execution of a QEBSM instruction
for a format 1 output queue.
002C 44 Signed 4 QSBOLCK QIOBK/QSD Output Lock Failure
PEI Code (32) Page Pin Failure 1 (QSBPP32)
The number of times CP Millicode could not pin a page
because the RCP-bypass assist is enabled and an access
exception condition exists for the host page frame
corresponding to the designated page.
0030 48 Signed 4 QSBPPF32 Page Pin Failure 1
PEI Code (33) Page Pin Failure 2 (QSBPP33)
The number of times CP Millicode could not pin a page
because an access exception condition exists that is a
higher priority than an addressing exception for fetching
the PTE for the designated page.
0034 52 Signed 4 QSBPPF33 Page Pin Failure 2
PEI Code (34) Page Pin Failure 3 (QSBPP34)
The number of times CP Millicode could not pin a page
because the PGSTE page-control-interlock PCL bit could
not be set for the page.
0038 56 Signed 4 QSBPPF34 Page Pin Failure 3
PEI Code (35) Page Pin Failure 4 (QSBPP35)
The number of times CP Millicode could not pin a page
because an overflow of the PGSTE pin count would occur.
003C 60 Signed 4 QSBPPF35 Page Pin Failure 4
PEI Code (36) Page Pin Failure 5 (QSBPP36)
The number of times CP Millicode could not pin a page
because the page-protection (P) bit is on in the STE or
PTE for the designated page and a store access is required
for the page.
0040 64 Signed 4 QSBPPF36 Page Pin Failure 5
PEI Code (37) Page Pin Failure 6 (QSBPP37)
The number of times CP Millicode could not pin a page
because the page-invalid (I) bit in the PTE is one for the
page and there are no available frames for page resolution
(i.e. the available-frames-descriptor-list origin (AFDLO)
for the running CPU contains zero).
0044 68 Signed 4 QSBPPF37 Page Pin Failure 6
PEI Code (38) Page Pin Failure 7 (QSBPP38)
The number of times CP Millicode could not pin a page
because the page-invalid (I) bit in the PTE is one for the
page and the HPMA resolve-host-page function has failed
to resolve the page for reasons other that PEI Code 37.
0048 72 Signed 4 QSBPPF38 Page Pin Failure 7
PEI Code (39) Page Pin Failure 8 (QSBPP39)
The number of times CP Millicode could not pin a page
because of a model dependent reason.
004C 76 Signed 4 QSBPPF39 Page Pin Failure 8
PEI Code (64) Page UnPin Failure 1 (QSBUP64)
The number of times CP Millicode could not unpin a page
because an access exception condition exists that is a
higher priority than an addressing exception for fetching
the PTE for the designated page.
0050 80 Signed 4 QSBUPF64 Page UnPin Failure 1
PEI Code (65) Page UnPin Failure 2 (QSBUP65)
The number of times CP Millicode could not unpin a page
because the PGSTE page-control-interlock PCL bit could
not be set for the page.
0054 84 Signed 4 QSBUPF65 Page UnPin Failure 2
PEI Code (66) Page UnPin Failure 3 (QSBUP66)
The number of times CP Millicode could not unpin a page
because an underflow of the PGSTE pin count would occur.
0058 88 Signed 4 QSBUPF66 Page UnPin Failure 3
PEI Code (67) Page UnPin Failure 4 (QSBUP67)
The number of times CP Millicode could not unpin a page
because the page-invalid (I) bit in the PTE is one for the
page.
005C 92 Signed 4 QSBUPF67 Page UnPin Failure 4
PEI Code (68) Page UnPin Failure 5 (QSBUP68)
The number of times CP Millicode could not unpin a page
because the contents of the PTE page-frame-real-address
(PFRA) indicate a page that is different from the frame
specified for the page by the host SBALE for the page.
0060 96 Signed 4 QSBUPF68 Page UnPin Failure 5
