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 | |
| 3bdafdff | 6 | w synthesize ptwrite events |
| 70d110d7 | 7 | p synthesize power events |
| 60b88d87 AH |
8 | e synthesize error events |
| 9 | d create a debug log | |
| 10 | g synthesize a call chain (use with i or x) | |
| 601897b5 | 11 | l synthesize last branch entries (use with i or x) |
| d1706b39 | 12 | s skip initial number of events |
| 60b88d87 | 13 | |
| 70d110d7 | 14 | The default is all events i.e. the same as --itrace=ibxwpe |
| 60b88d87 AH |
15 | |
| 16 | In addition, the period (default 100000) for instructions events | |
| 17 | can be specified in units of: | |
| 18 | ||
| 19 | i instructions | |
| 20 | t ticks | |
| 21 | ms milliseconds | |
| 22 | us microseconds | |
| 23 | ns nanoseconds (default) | |
| 24 | ||
| 25 | Also the call chain size (default 16, max. 1024) for instructions or | |
| 26 | transactions events can be specified. | |
| 601897b5 AH |
27 | |
| 28 | Also the number of last branch entries (default 64, max. 1024) for | |
| 29 | instructions or transactions events can be specified. | |
| d1706b39 | 30 | |
| 3bdafdff | 31 | It is also possible to skip events generated (instructions, branches, transactions, |
| 70d110d7 | 32 | ptwrite, power) at the beginning. This is useful to ignore initialization code. |
| d1706b39 AK |
33 | |
| 34 | --itrace=i0nss1000000 | |
| 35 | ||
| 36 | skips the first million instructions. |
