2021-12-28perf scripts python: intel-pt-events.py: Fix printing of switch eventsAdrian Hunter
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.

2021-05-21perf scripts python: exported-sql-viewer.py: Fix warning displayAdrian Hunter
Deprecation warnings are useful only for the developer, not an end user. Display warnings only when requested using the python -W option. This stops the display of warnings like: tools/perf/scripts/python/exported-sql-viewer.py:5102: DeprecationWarning: an integer is required (got type PySide2.QtCore.Qt.AlignmentFlag). Implicit conversion to integers using __int__ is deprecated, and may be removed in a future version of Python. err = app.exec_() Since the warning can be fixed only in PySide2, we must wait for it to be finally fixed there.

2020-04-16perf script: Add flamegraph.py scriptAndreas Gerstmayr
This script works in tandem with d3-flame-graph to generate flame graphs from perf. It supports two output formats: JSON and HTML (the default). The HTML format will look for a standalone d3-flame-graph template file in /usr/share/d3-flame-graph/d3-flamegraph-base.html and fill in the collected stacks. Usage: perf record -a -g -F 99 sleep 60 perf script report flamegraph Combined: perf script flamegraph -a -F 99 sleep 60 Committer testing: Tested both with "PYTHON=python3" and with the default, that uses python2-devel: Complete set of instructions: $ mkdir /tmp/build/perf $ make PYTHON=python3 -C tools/perf O=/tmp/build/perf install-bin $ export PATH=~/bin:$PATH $ perf record -a -g -F 99 sleep 60 $ perf script report flamegraph Now go and open the generated flamegraph.html file in a browser. At first this required building with PYTHON=python3, but after I reported this Andreas was kind enough to send a patch making it work with both python and python3.

ptwrite events The format of synthesized events is determined by the attribute config. For the formats for Intel PT power and ptwrite events, create tables and populate them when the synth_data handler is called. If the tables remain empty, drop them at the end. The tables and views, including a combined power_events_view, will display automatically from the tables menu of the exported exported-sql-viewer.py script. Note, currently only Atoms since Gemini Lake have support for ptwrite and mwait, pwre, exstop and pwrx, but all Intel PT implementations support cbr.

2019-06-05perf scripts python: exported-sql-viewer.py: Select find text when find bar ↵Adrian Hunter
is activated The user probably wants to replace the find text, so select the find text when the find bar is activated. That is fairly standard behaviour for search text entry. Entering text will replace the current text, but using edit keys (arrows, home, end etc) cancels the selection and enables editing.
