2022-02-15perf scripts python: intel-pt-events.py: Add Event TraceAdrian Hunter1-5/+50

2021-12-28perf scripts python: intel-pt-events.py: Fix printing of switch eventsAdrian Hunter1-10/+13
The intel-pt-events.py script displays only the last of consecutive switch statements but that may not be the last switch event for the CPU. Fix by keeping a dictionary of last context switch keyed by CPU, and make it possible to see all switch events by adding option --all-switch-events.

2019-03-06perf script python: Add Python3 support to intel-pt-events.pyTony Jones1-13/+19
Support both Python2 and Python3 in the intel-pt-events.py script There may be differences in the ordering of output lines due to differences in dictionary ordering etc. However the format within lines should be unchanged. The use of 'from __future__' implies the minimum supported Python2 version is now v2.6 Signed-off-by: Tony Jones <[email protected]> Acked-by: Adrian Hunter <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Seeteena Thoufeek <[email protected]> Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
2019-03-06perf script python: Remove mixed indentationTony Jones1-16/+16
Remove mixed indentation in Python scripts. Revert to either all tabs (most common form) or all spaces (4 or 8) depending on what was the intent of the original commit. This is necessary to complete Python3 support as it will flag an error if it encounters mixed indentation.
