DSP, SRB, SSRB, and WAIT trace entries

These trace entries represent the dispatch of a unit of work:

A DSP trace entry represents dispatch of a task
An SRB trace entry represents the initial dispatch of a service request
An SSRB trace entry represents dispatch of a suspended service request
A WAIT trace entry represents dispatch of the wait task

PR

pr: Identifier of the processor that produced the TTE.

ASID

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

WU-ADDR

wu-addr: Address of the task control block (TCB) for the current task or the work element block (WEB).

IDENT

The TTE identifier, as follows:

DSP: Task dispatch
SRB: Initial service request dispatch
SSRB: Suspended service request dispatch
WAIT: Wait task dispatch

CD/D

Blank

PSW----- ADDRESS-

The z/Architecture® 128-bit PSW address appears on two lines:

pswaddr: Two words, containing the 64-bit address portion of the PSW
pswctrl: Two words, containing the 64-bit "control" portion of the PSW

The PSW represents different data, depending on the type of work that was dispatched:

dsp-new- pswaddr / dsp-new- pswctrl: Program status word (PSW) to be dispatched
srb-new- pswaddr / srb-new- pswctrl: PSW to receive control on the SRB dispatch
ssrb-new pswaddr / ssrb-new pswctrl: PSW to receive control on the SSRB redispatch

UNIQUE-1/UNIQUE-2/UNIQUE-3

UNIQUE-4/UNIQUE-5/UNIQUE-6

gpr0----: General register 0
gpr1----: General register 1
psamodew: PSAMODEW field in the PSA
safnasid: LCCASAFN field in the logical configuration communication area (LCCA) and the related ASID
flg-srb: SRBFLGS field from the SRB
purgetcb: TCB (located in address space of the scheduler of the SRB or SSRB) that gets control if the SRB or SSRB abends and percolates

PSACLHS-

psaclhs-: String for the current lock held, from the PSACLHS field of the PSA.
psaclhs4: PSACLHS4 field of the PSA
srbhlhi-: SRBHLHI field in the SRB

This field will contain descriptive text for some SVC, SSRV, and PC trace entries. The descriptive text will not appear in SNAP, SYSUDUMP, or SYSABEND output.

PSALOCAL

psalocal: Locally locked address space indicator, from the PSALOCAL field of the PSA. This field will contain descriptive text for some SVC, SSRV, and PC trace entries. The descriptive text will not appear in SNAP, SYSUDUMP, or SYSABEND output.

PASD

pasd: Primary ASID (PASID) at trace entry. This field will contain descriptive text for some SVC, SSRV, and PC trace entries. The descriptive text will not appear in SNAP, SYSUDUMP, or SYSABEND output.

SASD

sasd: Secondary ASID (SASID) at trace entry. This field will contain descriptive text for some SVC, SSRV, and PC trace entries. The descriptive text will not appear in SNAP, SYSUDUMP, or SYSABEND output.

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.
