- i synthesize instructions events
- b synthesize branches events
- c synthesize branches events (calls only)
- r synthesize branches events (returns only)
- x synthesize transactions events
- w synthesize ptwrite events
- p synthesize power events
- e synthesize error events
- d create a debug log
- g synthesize a call chain (use with i or x)
- l synthesize last branch entries (use with i or x)
- s skip initial number of events
- The default is all events i.e. the same as --itrace=ibxwpe,
- except for perf script where it is --itrace=ce
- In addition, the period (default 100000, except for perf script where it is 1)
- for instructions events can be specified in units of:
- i instructions
- t ticks
- ms milliseconds
- us microseconds
- ns nanoseconds (default)
- Also the call chain size (default 16, max. 1024) for instructions or
- transactions events can be specified.
- Also the number of last branch entries (default 64, max. 1024) for
- instructions or transactions events can be specified.
- It is also possible to skip events generated (instructions, branches, transactions,
- ptwrite, power) at the beginning. This is useful to ignore initialization code.
- --itrace=i0nss1000000
- skips the first million instructions.
