perf scripts intel-pt-events.py: Fix IPC output for Python 2

2023-05-17T09:50:19Z

[ Upstream commit 1f64cfdebfe0494264271e8d7a3a47faf5f58ec7 ] Integers are not converted to floats during division in Python 2 which results in incorrect IPC values. Fix by switching to new division behavior.

perf scripts python: intel-pt-events.py: Fix printing of switch events

2022-01-05T11:42:40Z

commit 0f80bfbf4919e32f52fe1312c3900ff4fbb7eeb9 upstream. 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.

perf scripting python: Assign perf_script_context

2021-06-01T13:03:33Z

The scripting_context pointer itself does not change and nor does it need to. Put it directly into the script as a variable at the start so it does not have to be passed on each call into the script.
