Function Code X'0003' - Designated Guest Information
Function code X'0003' returns guest CPU resource information useful to an authorized application performing CPU performance monitoring and management.
Use of this function code is authorized in the user directory by OPTION STHYI-GUEST.
When function code X'0003' is specified, general register R2 contains the guest logical address of a 4 KB response buffer, which must be on a 4 KB boundary or a specification exception is recognized.
This function code provides information for the Guest specified in the 8-byte buffer located at the guest logical address in R1+1. If the buffer is not aligned on a doubleword boundary a specification exception is recognized.
When the instruction completes with condition code 3, the response buffer located by the guest logical address in R2 is unchanged. When the instruction completes with condition code 0, guest information will be stored into the buffer at the guest logical address specified by register R2.
The possible nonzero return codes for this function code are:
- CC=3 RC=4
- Unsupported function code. Buffer is unchanged.
- CC=3 RC=8
- Not authorized for the function code. Buffer is unchanged.
- CC=3 RC=12
- Missing or invalid guest name. Buffer is unchanged.
- CC=3 RC=16
- Named guest is not logged on. Buffer is unchanged.
Function Code X'0003' Response Buffer Format (INF3BK)
INF3BK DSECT in HCPINFBK COPY of HCPGPI MACLIB describes the response buffer format and might include information regarding usage of the fields in the DSECT.
The common header section (INFCHDR DSECT) is placed at the beginning of the response buffer and identifies the length of the response.
The list designation fields in the common header are stored as zeroes.
The guest information follows the common header at INF3GSTI and is mapped by INF3GST DSECT.
The high-frequency counters starting at field INF3GIWSC report data collected when Monitor high-frequency sampling is active. The values are reset to zero when Monitor commands are issued that deactivate high-frequency sampling, and remain zero while it is inactive. MONITOR SAMPLE RATE is used to set the frequency of the guest state sampling which should be more frequent than the sampling interval. The high-frequency sampling is activated using MONITOR SAMPLE ENABLE USER for the users of interest.
The version number (INF3VRSN) in the function code X'0003' response header can be used to clearly identify whether the function code is at the required service level and can be used by applications to show actual and required version in messages when required support is missing.

High frequency sampler counts
These counts are the number of times that CP and IFL CPUs of the
guest are observed in each state. These counts are reset to zero
when Monitor commands are issued that disable high-frequency
sampling. 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
