1 i synthesize instructions events
2 b synthesize branches events
3 c synthesize branches events (calls only)
4 r synthesize branches events (returns only)
5 x synthesize transactions events
6 w synthesize ptwrite events
7 p synthesize power events
8 e synthesize error events
10 g synthesize a call chain (use with i or x)
11 l synthesize last branch entries (use with i or x)
12 s skip initial number of events
14 The default is all events i.e. the same as --itrace=ibxwpe,
15 except for perf script where it is --itrace=ce
17 In addition, the period (default 100000, except for perf script where it is 1)
18 for instructions events can be specified in units of:
24 ns nanoseconds (default)
26 Also the call chain size (default 16, max. 1024) for instructions or
27 transactions events can be specified.
29 Also the number of last branch entries (default 64, max. 1024) for
30 instructions or transactions events can be specified.
32 It is also possible to skip events generated (instructions, branches, transactions,
33 ptwrite, power) at the beginning. This is useful to ignore initialization code.
37 skips the first million instructions.
