All counts of CPs, IFLs, and zIIPs and capacity values
are based on quantities of cores when multithreading is
enabled. While virtual CPUs are thread dispatched
they have the potential of consuming an entire core.
Therefore virtual CP, IFL and zIIP counts are counts of
virtual CPUs but treated as counts of cores.

INFCHDR - INFBK Common Header of Response Buffer
- This common header section defines the beginning
of the response buffer for function codes that
insert it at the start of the function-code-specific
response buffer definition.
- The INFxBK of each function-code-specific response
buffer imbedding this common header describes the
changes introduced for all version codes as a set
of equates defined for the redefinition of INFCVRSN.
The service level that introduced the change is also
noted in the comment on the equates.
- Function codes that don't return a list will have
zero values in INFCLSOF, INFCENLN and INFCCTEN.
- Function codes that return a list but have no list
data to return will return zero values in INFCLSOF
and INFCCTEN, but returns the entry length in INFCENLN.
- If the definition of this common header changes then
the version number for all function codes that use
it will be increased to indicate the change in the
response buffer format for that function code.
- The length of the common header section (INFCHDR) will
never change to prevent shifting offsets of fields
in the function-code-specific block following the
common header.

Function code x'0001': Hypervisor Environment Information
This function code reports on the environment of the
invoker of STHYI.
The response buffer for function code x'0001' consists
of five or more sections of data:
Header Section (INF1BK DSECT, imbeds INF1CHDR)
Machine Section (INF1MAC DSECT)
Partition Section (INF1PAR DSECT)
Hypervisor Section 1 (INF1HYP DSECT)
Guest Section 1 (INF1GST DSECT)
Hypervisor Section 2 (may not be present)
Guest Section 2 (may not be present)
Hypervisor Section 3 (may not be present)
Guest Section 3 (may not be present)
One to three levels of hypervisors and guests may be
reported. When the guest is running second level or
higher, hypervisor/guest section 1 is filled in by the
hypervisor running closest to the hardware, with its
guest filling in the next section, etc. for a maximum
of 3 levels.
The format of this response buffer is determined by the
hypervisor closest to the LPAR. When running directly
in a partition, there is only one level of hypervisor
involved in constructing the response so the version is
the same for all sections. However when running second
level the version of this block is generally determined
by the first level hypervisor.
The formats of the pairs of hypervisor and guest
sections may differ. The specified version number
describes the format of that section.
Use of this function code is authorized in the User
Directory by OPTION STHYI-UTIL.
Error responses:
- CC=3 RC=4 - Unsupported function code
- The response buffer is not modified.
- CC=3 RC=8 - Not authorized for function code
- The response buffer is not modified.

Otherwise they are monotonically
increasing values. INF1YMONH
provides the high-frequency
sampling interval for the state
testing. For each virtual CPU
type, the order of the count
fields is the order that the
states are tested so that if a
vCPU is in multiple states, it is
counted with the first state that
matches so that it is counted in
one and only one state. The one
exception is that when a guest is
on the dormant list and SVM wait
they are counted in both
INF3GDLSC and INF3GDSSC for
virtual CPs and for IFLs, both
INF3GDLSI and INF3GDSSI. The
values are aggregate values for
all guest virtual CPUs of that
type. See Monitor record MRUSEINT

The response buffer for function code x'0004' consists

- use offset to Resource Pool list, length of entry,

- The offset in INFCLSOF is from the beginning
of the INF4BK.
- if the count is zero there is no list so the offset
and length will be zero.
- Resource Pool list. The list is returned as an array
with the count of entries, offset to the first entry
and the entry length defined by the common header.
- The array entry structure is defined by INF4POOL DSECT.
