perf scripts python: exported-sql-viewer.py: Fix pattern matching with Python 3

2025-06-27T10:05:15Z

[ Upstream commit 17e548405a81665fd14cee960db7d093d1396400 ] The script allows the user to enter patterns to find symbols. The pattern matching characters are converted for use in SQL. For PostgreSQL the conversion involves using the Python maketrans() method which is slightly different in Python 3 compared with Python 2. Fix to work in Python 3.

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.
