data (includes all frames which
have the FRMCP bit on in FRMCSB0
of their FRMTEs, except for VDISK
frames, which are CP owned, but

count of frames that will be
included in a CP dump, and is
used to allocate additional space
for a CP dump as CP grows.
Compare and Swap logic must be
used to update this field.

FRMTEs which have not yet been
checked to see if they are
usable.
0040 64 Signed 8 RSALGFRM Count of usable frames >= 2G.
0048 72 Signed 8 RSAGOFFL Count of offline frames >= 2G.

is not exact until testing of
large real storage has ended.
0058 88 Signed 8 RSASTORL Highest real host storage
address. This is uncapped as
calculated from SCLP storage data
or Diagnose. This value is not
adjusted.
0060 96 Address 8 RSALG1ST Address of first FRMTE for frames
>= 2G. This address is above
any offline frames at the 2G
line. It does not skip 'not-init'
frames.
0068 104 Address 8 RSALGLST Address of last FRMTE for frames
>= 2G. This address is below
any offline frames at the high
end of storage. It does not skip
'not-init' frames.
0070 112 Address 8 RSANOTIB Address of the FRMTE for the
lowest frame >= 2G marked
'not-init'. If greater than
RSALGLST then all frames >= 2G
are initialized and RSAGSTOR is
accurate.
0078 120 Signed 8 RSA2GLCK (3) >= 2G available list lock.
This lock is obtained & released
via macros HCPLK2GA and HCPUL2GA.
0090 144 Address 8 RSA2GAHD >= 2G available list lock
queue header. Points to a FRMTE.
0098 152 Address 8 * Reserved for IBM use
00A0 160 Signed 8 RSA2GAVL Count of frames on the >= 2G
available list.
00A8 168 Dbl-Word 8 * (0) Insure lock is doubleword
aligned.
00A8 168 Dbl-Word 8 RSAPRLK (3) PTRM address space resolution
lock. This is a formal exclusive
lock, managed by HCPLCK. This
lock serializes RSAASITB during
PTRM address space creation.
00C0 192 Dbl-Word 8 RSAASITB (16) Table of i-ASITs for the PTRM
address spaces. RSAPRLK must be
held to validate an entry in this
table. Each table entry is mapped
by the HCPAMTE control block.

forward pointer. PPAL is actually
a list of PGMBKs and DAT frames.
014C 332 Signed 4 RSAPPABW Paged PGMBK aging list (PPAL)
backward pointer.
0150 336 Signed 4 RSAPPTLK PAGEABLE PAGE TABLE LOCK. THIS IS
AN INFORMAL SPIN LOCK. THE LOCK
MUST BE HELD WHEN ADDING FRMTES
TO OR REMOVING FRMTES FROM the
DPPL, the PPAL, or the misc free
storage aging queue. RSAPPTLK IS
SET TO THE ADDRESS OBTAINING THE
LOCK. WHEN FREE, ITS VALUE IS
ZERO. USE COMPARE AND SWAP TO
UPDATE. (This lock must also be
held when decrementing a PGMFRMCT
or PGMMIGCT field to zero, and
then seeing if we can put that
PGMBK on the DPPL.)

space is guaranteed to designate
both a null access list (RSANALD)
and a null authority table, and

storage blocks which like DAT
tables must be aged before reuse.
End of queue is a zero pointer.
0188 392 Dbl-Word 8 * (0) Insure lock is doubleword
aligned.
0188 392 Dbl-Word 8 RSASHRLK (3) A shared/exclusive defer lock

to resolve page faults in a group
of blocked pages. Used when there
are no frames on the available
list.
