ASCBK DSECT
Cross Reference (Contains links to field and bit definitions)
ASCBK Prolog
NAME : HCPASCBK
DESCRIPTION: Address-Space-Control Block
DSECT : ASCBK
FUNCTION : Contain information about an address space.
The ASCBK is essentially CP's software extension
to the ASN-second-table entry (ASTE) describing
the address space.
LOCATED BY : ASTASCBK field of the ASTE defining the address space
CREATED BY : HCPASMCR
DELETED BY : HCPASMDS
SERIALIZED : Many fields in the ASCBK are static for the life of
the address space. Most of the rest of them are
serialized by the ASCBK lock, the lockword for which
is at ASCLOCK.
Various fields are serialized by:
- ASCBK lock (ASCLOCK)
- MP Defer
- Console-function mode
- XSTSTATL
COMMENTS : The ASCBK must reside on a doubleword boundary.

0000 0 Structure ASCBK Address-Space-Control Block
Address space management area.
This area contains fields used to manage and locate the
address space itself. All fields in this area are
serialized by the ASCBK lock (the lockword at ASCLOCK)
unless specifically noted otherwise.
0000 0 Address 4 ASCOFPNT Forward pointer to next ASCBK in
chain of ASCBKs anchored from
VMDASCBK of the owner's base
VMDBK. This chain defines what
address spaces are owned by the
VMDBK. SYSTEM-owned spaces are
anchored from the SYSTEM VMDBK.
This field is serialized by the
owner's ASCBK-queue lock
(VMDASCLK). The chain is ended by
a forward pointer of zero.
0004 4 Address 4 ASCSFPNT Forward pointer to next ASCBK in
the chain of ASCBKs anchored from
RSASHRSP in HCPRSM. This is the
chain of shareable address
spaces, and is serialized by the
lock at RSASHRLK. The chain is
ended by a forward pointer of
zero.
0008 8 Address 4 ASCSBPNT Backward pointer to previous
ASCBK in the chain of ASCBKs
anchored from RSASHRSP in HCPRSM.
The ASCSBPNT field of the first
ASCBK in the chain is zeros.
000C 12 Signed 4 ASCSEQNO r-access sequence number,
incremented on address space
reset to match the ASTE sequence
number (ASTSN). r-access i-ASITs
(which use this sequence number)
are sensitive to address space
reset operations.
0010 16 Character 32 ASCSPCID (0) Space identification:
0010 16 Character 8 ASCUSRID Owning userid, padded on right
with blanks.
0018 24 Character 24 ASCNAME Address space name, padded on
right with blanks.
0030 48 Address 4 ASCSNTBK Pointer to owning SNTBK
(ASCTSNT=1)
0034 52 Bitstring 4 * Reserved for IBM use
0038 56 Dbl-Word 8 ASCEASIT (0) ASCBK e-ASIT.
0038 56 Address 4 ASCASTE Pointer to ASN-Second-Table Entry
(ASTE) for the address space.
Serialized by task ownership at
creation, thereafter unchanged
until space is destroyed.
003C 60 Signed 4 ASCSCRSN Address space creation sequence
number.
0040 64 Address 4 ASCSPIBK Pointer to chain of SPIBKs
designating which users are
permitted to attach this space to
their guest-use access list. This
field is serialized by the
space-permission- manager lock
(RSASPMLK in HCPRSMCM).
0044 68 Address 4 ASCOWNER Pointer to (base) VMDBK of owning
virtual configuration, or SYSTEM
VMDBK if CP owned.
0048 72 Dbl-Word 8 ASCLOCK (3) Lockword for shared/exclusive
defer lock, protecting fields in
the ASCBK and ASTE. For System
Utility address spaces managed by
HCPVAMAP and HCPVAMDP and
HCPASURO, ASCLOCK exclusive is
sufficient to invalidate a SEGTE
without SEGTRANS. A share of
ASCLOCK must be obtained *before*
trying to obtain SEGTRANS when
validating the SEGTE.
The presence of discontiguous defined storage via
DEF STOR CONFIG does not change the definition, though
there is now no guarantee that all bytes below
ASCHIBYT are defined or addressable (therefore, all
references to "size" in the ASCHIBYT definition have
been changed to "address limit").
0060 96 Dbl-Word 8 ASCHIBYT The highest addressable byte of
storage in this address space.
The "address limit" of the
address space in bytes is one
greater than this value. Since
X'FFFFFFFF_FFFFFFFF' is a valid
address in ESAME, code must check
for wrap-to-zero when adding one
to ASCHIBYT to calculate the
"address limit" of the address
space in bytes. *NOTE** ASCHIBYT,
in ESAME, is similar to, but not
identical to, ASCSSIZE in
ESA/390.
0068 104 Dbl-Word 8 ASCDEFSZ Defined storage size in
addressable bytes, minus one. If
DEF STOR CONFIG was used to
define multiple discontiguous
extents of addressable defined
storage, this field contains the
sum of the sizes in bytes of all
of the individual extents (minus
one). Minus one notation used so
that a total size of 16 Ekabytes
may be represented without
ambiguity (as
x'FFFFFFFF_FFFFFFFF').

00000001 ASCSTS32 X'01' Segment table size = 128
bytes, addressing up to 32M,
maximum virtual address =
x'01FFFFFF'. For guest primary
address space ASCBKs, ASCSTSIZ =
ASCSTS32 indicates that the
segment table resides in the
VMDLSEG field at the beginning of
the guest base VMDBK. Note:
ASCSTS32 == STDSTL01 Notes :
ASCSTSIZ may have values in
between ASCSTS32 (32M) and
ASCSTS1G (1G). In these cases the
value represents the size of the
segment table when a segment
table is allocated from a free
storage frame. The remainder of

for GUESTPERM type VMDBK free
storage.
0000003F ASCSTS1G X'3F' Segment table size = 4096
bytes, addressing up to 1024M,
maximum virtual address =

(1G) and ASCSTS2G (2G). In these
cases the value represents the
size of the segment table when
the remainder of the second frame
of the segment table (past the
end of the contiguous segment
table) was allocated from a free
storage frame. The remainder of

The following fields are serialized by the available list
replenishment demand scan lock. They are used to sort the
queue of stolen FRMTEs by address space (for user address
space frames, VDISK address space frames, and NSS/DCSS
shared segment frames) and by virtual address megabyte
(for NSS/DCSS shared segment frames only).
00E0 224 Address 4 ASCSTLNX Address of the next ASCBK for an
address space from which pages
were stolen in this iteration of
the steal task. Each iteration
will initialize this field to
x'FFFFFFFF'. When the entire
queue of FRMTEs is sorted (by
address space), the last ASCBK in
this chain will have x'FFFFFFFF'
in this field.
00E4 228 Address 4 ASC1STFR Address of the first FRMTE that
was stolen from this address
space in this iteration of the
steal task, and anchor of the
queue of all FRMTEs stolen from
this address space by this
iteration of the steal task
(queued by FRMTE field FRMFPNT).
Each iteration will initialize
this field to x'FFFFFFFF', and a
FRMTE FRMFPNT value of
x'FFFFFFFF' indicates that it is
the last FRMTE on the queue.
00E8 232 Address 4 ASCLSTFR (0) Address of the last (processed)
FRMTE that was stolen from this
address space in this iteration
of the steal task. Each iteration
will initialize this field to
x'FFFFFFFF', and a FRMTE FRMFPNT
value of x'FFFFFFFF' indicates
that it is the last FRMTE on the
queue. Only used when sorting
FRMTEs for normal user pages,
which do not neet to be sorted by
segment (virtual address
megabyte). For NSS/DCSS shared
segment page FRMTEs, this field
is redefined as ASC1STPG.
00E8 232 Address 4 ASC1STPG Address of the first PGMBK for
this address space from which
pages were stolen in this
iteration of the steal task, and
anchor of the queue of all PGMBKs
for this address space from which
pages were stolen in this
iteration of the steal task
(queued by PGMBK field PGMNXPGM /
PGMGNPGM). Each iteration will
initialize this field to
x'FFFFFFFF', and x'FFFFFFFF' in a
PGMBK's PGMNXPGM / PGMGNPGM field
indicates that it is the last
PGMBK on the list. Only used when
sorting FRMTEs for NSS/DCSS
shared segment pages, which must
be sorted by segment (virtual
address megabyte). For normal
user page FRMTEs, this field is
redefined as ASCLSTFR.
00EC 236 Address 4 ASCLSTPG Address of the last PGMBK for
this address space from which
pages were stolen in this
iteration of the steal task. Each
iteration will initialize this
field to x'FFFFFFFF', and
x'FFFFFFFF' in a PGMBK's PGMSTNXT
field indicates that it is the
last PGMBK on the list. Only used
when sorting FRMTEs for NSS/DCSS
shared segment pages, which must
be sorted by segment (virtual
address megabyte).
The following two fields belong up above with ASCIACCT and
ASCRACCT, but were placed here to avoid recompiles. They
should be moved (and this block comment deleted) when this
control block is next restructured.
00F0 240 Signed 4 ASCITRCT Count of in-process i-access
manual translations in the
address space.
00F4 244 Signed 4 ASCRTRCT Count of in-process r-access
manual translations in the
address space.
ESAME Region Translation Cache
ASCR0STD, ASCR0RFT, ASCR0RST, and ASCR0RTT, are in
ASCE format, that is, the bits which define the table
level are DT bits (level of the designated table), not
R*TE format TT bits (which indicate the level of the
table containing the R*TE). Any ASCR0R*T fields
corresponding to table levels higher than that
designated by the current ASCE are set to zero.
Serialization of these fields is as follows: For the
entry designating the current highest level table for
the address space (that is, the entry which matches the
current ASCE), PTIL must be held exclusive. For all
lower level table entries, either PTIL must be held
exclusive, or a share of PTIL must be held along with
RTETRANS in the next higher level R*TE which designates
the same table.

ESAME HDPBK queues - HDPBKs are the programming areas
associated with host region and segment tables. To make
traversal of sparsely populated tables easier, we keep
several doubly linked queues of HDPBKs. The first HDPBK
queue is the "addressable storage" HDPBK queue, containing
queue is the "addressable" queue, and contains HDPBKs
(potentially representing different table levels) for
each addressable extent of storage, in ascending virtual
address range order. The remaining HDPBK queues contain
all of the HDPBKs for a given table level, again, in
ascending virtual address range order.
The region table(s) (if any) and segment table for region
0 are pre-allocated when the space is created. Therefore,
an HDPBK representing region 0 will be the first HDPBK on
each queue.
Each queue header can also be mapped using the HDPQPTRA
HDPBK Queue Pointer Area DSECT define in HCPHDPBK.
>> Initialization and maintaining of these queues has
>> been deferred until the initial code base is working,
>> as these are primarily used as "accelerators" for
>> routines which traverse HDPBKs
>> Queue headers will remain 0 until further notice.

ESAME Address Space Storage Configuration area
This array contains address extent information for each
defined address extent. For most address spaces, there
will only be one extent defined, from 0 to ASCHIBYT. If
the DEFine STORage CONFIGuration command was used to
define multiple discontiguous address extents, this array
contains one additional entry for each additional address
extent defined. Up to eight extents are allowed, the
first extent must begin at address zero.
Individual array elements are mapped by STCONFIG DSECT.
Array elements must be sorted in ascending virtual address
order. Address ranges must not overlap, and must not be
contiguous.
