PCIS trace entries

A PCIS trace represents a PCI store instruction.

PR

pr: Identifier of the processor that produced the TTE.

ASID

home: Home address space identifier (ASID) associated with the TTE.

TCB-ADDR

tcb-addr: Address of the task control block (TCB) for the current task for which the TTE was produced.

IDENT

The TTE identifier, as follows:

PCIS

PCI store instruction.

CD/D

pfid: The PCIE function identifier for the PCIE device.

PSW----- ADDRESS-

• cc: Condition code from the PCI store instruction.
• reqaddr: Address of the program that requested the PCI store instruction to be issued.

UNIQUE-1/UNIQUE-2/UNIQUE-3

UNIQUE-4/UNIQUE-5/UNIQUE-6

• traceid: Program defined trace identifier that can be used to determine why the PCI store instruction is being issued.
• operand1_operand1: First operand on the PCI store instruction.
• operand2_operand2: Second operand on the PCI store instruction.
• operand3_operand3: Third operand on the PCI store instruction.

PSACLHS-

psaclhs-: String for the current lock held, from the PSACLHS field of the PSA.

PSACLHSE-

psaclhse-: Extended string for the current lock held, from the PSACLHSE field of the PSA.

PSALOCAL

psalocal: Locally locked address space indicator, from the PSALOCAL field of the PSA.

PASD

pasd: Primary ASID (PASID) at trace entry.

SASD

sasd: Secondary ASID (SASID) at trace entry.

TIMESTAMP-RECORD

timestamp-------: Time-of-day (TOD) clock value when system trace created the trace entry. The value is in the same format as the time stamp on logrec data set records.

CP

The CP column contains 2 hex digits of the processor model dependent information, which is intended to identify the physical CP that made the trace entry. CP is only provided when formatting SYSTRACE under IPCS. CP is not provided for SYSUDUMP, SYSABEND, or SNAP.
