Hex Dec Type/Val Lng Label (dup) Comments
---- ---- --------- ---- -------------- --------
0000 0 Structure TOPBK CPU Topology Block
0000 0 Address 4 TOPPARNT Pointer to parent TOPBK (or zero
if this is the top level TOPBK
0004 4 Address 4 TOPCHILD Pointer to first child TOPBK of
this TOPBK (or zero if this is
the lowest level TOPBK)
0008 8 Address 4 TOPSIBLG Pointer to the next sibling
TOPBK. TOPSIBLG pointers form a
circular singly- linked list of
sibling TOPBKs. Siblings are
TOPBKs at the same nest level
(TOPNL) which have the same
parent TOPBK (TOPPARNT).
000C 12 Bitstring 1 TOPNL Nest level. Corresponds to the
nest level field in
containter-type TLEs in the STSI
15.1.x response. Values range
between 1 and x-1.
000D 13 Bitstring 1 TOPCNTID Container ID. This field
corresponds to the container ID
found in the STSI 15.1.x response
for container-type TLEs.
000E 14 Bitstring 2 * Reserved
0010 16 Dbl-Word 8 TOPCPUMK Mask of CPUs defined to be in
this branch of the topology tree.
This mask is derived from the
STSI 15.1.x response.
0018 24 Dbl-Word 8 TOPASSOC Mask of CPUs associated with this
TOPBK. If this is the lowest
level TOPBK, this mask is the OR
of all DSVASSOC for all DSVBKs in
the TOPDSVBK list. If this is not
the lowest level TOPBK, this is
the OR of all TOPASSOC for all
children TOPBKs. Notes : TOPASSOC
may differ from TOPCPUMK if there
are CPUs that are configured in
the partition, but not associated
with DSVBKs. However, usually
TOPASSOC and TOPCPUMK will be
identical. The times when they do
not match are in the middle of a
topology change, or if a CPU is
logically offline.
0020 32 Dbl-Word 8 TOPUNPRK Mask of associated CPUs which are
currently in the unparked state.
If this is an NL=1 TOPBK, this is
the OR of all DSVUNPRK for all
DSVBKs in the TOPDSVBK lists. If
NL>1, this is the OR of all
TOPUNPRK for all children TOPBKs.
0028 40 Dbl-Word 8 TOPCPUPL (0) Array of CPU masks indexed by
polarization value
0028 40 Dbl-Word 8 TOPCPUHZ Mask of horizontal CPUs
0030 48 Dbl-Word 8 TOPCPUVL Mask of vertical low CPUs
0038 56 Dbl-Word 8 TOPCPUVM Mask of vertical medium CPUs
0040 64 Dbl-Word 8 TOPCPUVH Mask of vertical high CPUs
0048 72 Address 4 TOPDSVBK (0) Table of pointers to the first
DSVBK which contains CPUs of the
same type, corresponding to this
lowest level TOPBK (or zero if
this is not a lowest level
TOPBK). Table indexed by CPU type
0048 72 Address 4 TOPDSVCP CP type DSVBKs
004C 76 Address 4 *
0050 80 Address 4 TOPDSVZA zAAP type DSVBKs
0054 84 Address 4 TOPDSVIF IFL type DSVBKs
0058 88 Address 4 TOPDSVIC ICF type DSVBKs
005C 92 Address 4 TOPDSVZI zIIP type DSVBKs
00000018 TOPDsvTableLen *-TOPDSVBK Length of DSVBK table
Notes : TOPCAPAC and TOPRCAP for lowest level TOPBKs
are the (per CPU type) sums of DSVCAPAC and
DSVRCAP for all DSVBKs in the TOPDSVBK chains
which are not dedicated (FTRNTDED). For higher
level TOPBKs, TOPCAPAC and TOPRCAP are the sums
for all lower level TOPBKs below this TOPBK in
the topology tree.
0060 96 Bitstring 24 TOPCAPAC (0) The amount of unparked CPU
capacity for all CPUs associated
with this TOPBK, indexed by CPU
type. A value of 1.0 represented
scaled as x'10000' is a whole
real CPU of capacity. This is an
unsigned value, as a CPU will
never have negative capacity.
0060 96 Signed 4 TOPCAPCP CP capacity
0064 100 Signed 4 *
0068 104 Signed 4 TOPCAPZA zAAP capacity
006C 108 Signed 4 TOPCAPIF IFL capacity
0070 112 Signed 4 TOPCAPIC ICF capacity
0074 116 Signed 4 TOPCAPZI zIIP capacity
0078 120 Bitstring 24 TOPRCAP (0) The amount of remaining capacity
which hasn't been earmarked for a
VMDBK with affinity to a DSVBK
underneath this TOPBK, indexed by
CPU type. This value is in the
same units as TOPCAPAC, however,
it is a signed number, as we may
dole out more capacity than we
have unparked.
0078 120 Signed 4 TOPRCAPCP CP remaining capacity
007C 124 Signed 4 *
0080 128 Signed 4 TOPRCAPZA zAAP remaining capacity
0084 132 Signed 4 TOPRCAPIF IFL remaining capacity
0088 136 Signed 4 TOPRCAPIC ICF remaining capacity
008C 140 Signed 4 TOPRCAPZI zIIP remaining capacity
0090 144 Address 4 TOPLVLFP Nest level list forward pointer.
The nest level list is a
circular, single- linked list of
all TOPBKs of a given nest level
(TOPNL). TOPBKs in this list do
not necessarily share the same
parent TOPBK (TOPPARNT).
0094 148 Signed 2 TOPCPUCT (24) Array of counts of CPUs which are
associated with DSVBKs underneath
this TOPBK, indexed first by CPU
type, then by polarization.
00000030 TOPCPUCT_len *-TOPCPUCT Length (bytes) of the
entire TOPCPUCT array
00C4 196 Signed 2 TOPCPUCR (24) Array of counts of CPUs indexed
first by CPU type, then by
polarization. Copied from
TOPCPUCT for use during the CPU
park/unpark calculation routine.
0000001F TOPSIZE (*-TOPBK+7)/8 size in double
words
000000F8 TOPBSIZE TOPSIZE*8 size in bytes
00000100 TOPBK_aligned_len
256 Byte-alignment on which we
will "allocate" TOPBKs
00000008 TOPBK_Shift 8 Number of bits to shift to
convert between TOPBK count and
byte units (TOPBKs are allocated
as 256 bytes long)
