Trace Format¶

QEMU4V is able to generate traces of program execution. Here is the description of the trace format.
The QEMU4V trace contains records of the following kinds: instruction records, memory access records, register write records.

Instruction record¶

Appears in the trace when the corresponding instruction from the target program has been executed.
The record format is as follows:

<time> <scale> <cpu> [IT|IS] (<inst_id>) <addr> <opcode> [A|T|X] <mode>_<security> : <disasm>

The record fields are described in the following table:

Field	Timestamp	Value
<time>	Description	Integer
<scale>	Description	Value
<cpu>	Description	Value
[IT<nowiki>	</nowiki>IS]	Description	Value
<inst_id>	Description	Value
<addr>	Description	Value
<opcode>	Description	Value
[A	T	X]	Description	Value
<mode>	Description	Value
<security>	Description	Value
<disasm>	Description	Value
