The script also displays branches, and supports 2 additional modes selected by option: - --insn-trace - instruction trace - --src-trace - source trace + - --insn-trace - instruction trace + - --src-trace - source trace + +The intel-pt-events.py script also has options: + + - --all-switch-events - display all switch events, not only the last consecutive. + - --interleave [<n>] - interleave sample output for the same timestamp so that + no more than n samples for a CPU are displayed in a row. 'n' defaults to 4. + Note this only affects the order of output, and only when the timestamp is the + same. As mentioned above, it is easy to capture too much data. One way to limit the data captured is to use 'snapshot' mode which is explained further below. |
