| 12 | The default is all events i.e. the same as --itrace=ibxe |
| 13 | |
| 14 | In addition, the period (default 100000) for instructions events |
| 15 | can be specified in units of: |
| 16 | |
| 17 | i instructions |
| 18 | t ticks |
| 19 | ms milliseconds |
| 20 | us microseconds |
| 21 | ns nanoseconds (default) |
| 22 | |
| 23 | Also the call chain size (default 16, max. 1024) for instructions or |
| 24 | transactions events can be specified. |
| Adrian Hunter | 601897b | 2015-09-25 16:15:39 +0300 | [diff] [blame] | 25 | |
| 26 | Also the number of last branch entries (default 64, max. 1024) for |
| 27 | instructions or transactions events can be specified. |
| Andi Kleen | d1706b3 | 2016-03-28 10:45:38 -0700 | [diff] [blame] | 28 | |
| 29 | It is also possible to skip events generated (instructions, branches, transactions) |
| 30 | at the beginning. This is useful to ignore initialization code. |
| 31 | |
| 32 | --itrace=i0nss1000000 |
| 33 | |
| 34 | skips the first million instructions. |
