TRCIT, Trace Instrumentation

The TRCIT characteristics are:

Purpose

Generates an instrumentation packet in the trace.

Configuration

This instruction is present only when FEAT_ITE is implemented. Otherwise, direct accesses to TRCIT are UNDEFINED.

Attributes

TRCIT is a 64-bit System instruction.

VALUE, bits [63:0]

Value to be included in the Instrumentation packet.

Executing TRCIT

Accesses to this instruction use the following encodings in the System instruction encoding space:

TRCIT <Xt>

op0	op1	CRn	CRm	op2
0b01	0b011	0b0111	0b0010	0b111

if !IsFeatureImplemented(FEAT_ITE) then UNDEFINED; elsif PSTATE.EL == EL0 then AArch64.TRCIT(X[t, 64]); elsif PSTATE.EL == EL1 then AArch64.TRCIT(X[t, 64]); elsif PSTATE.EL == EL2 then AArch64.TRCIT(X[t, 64]); elsif PSTATE.EL == EL3 then AArch64.TRCIT(X[t, 64]);
