Counter data section

This section contains various counters for the address space for the period that the record represents. This section is only produced when SMF30COUNT has been specified in the SMFPRMxx member or via the SETSMF command. The data is only collected when Hardware Instrumentation Services (HIS) has enabled the appropriate counter set that the data is derived from. Currently, all data is derived from the Instruction Counter in the Basic Counter Set. Therefore, HIS must have enabled the Basic Counter Set for collection to be accurate.

Triplet Information

This section is located on the record using the following triplet fields, which are located in the “header/self-defining” section:

Offset: SMF30CDO
Length: SMF30CDL
Number: SMF30CDN - Reports the number of counter data sections on the current record. This can be “0”, indicating the counter data section does not exist.

Offsets		Name	Length	Format	Description
0	0	SMF30InstFlgs1MRS	1	binary	Instruction Counter related flags. If a bit in this byte is on in the subtype 2/3 record, it is on in the subtype 4 record. Similarly, this holds between subtype 4 and subtype 5 records. Bit Meaning when set 0 When on, there was a disruption in the collection of instruction counts or the counts could not be obtained. 1 The following fields contain incomplete data (SRM could not deliver deltas or values for this interval): SMF30_Inst_CP_Enclave SMF30_Inst_Offload_Enclave SMF30_Inst_OffloadOnCP_Enclave SMF30_Inst_CP_DepEnc SMF30_Inst_Offload_DepEnc SMF30_Inst_OffloadOnCP_DepEnc
1	1		7	binary	Reserved
