perf scripting python: exported-sql-viewer.py: Factor out libxed.py

2021-06-01T13:05:08+00:00

Factor out libxed.py so it can be reused. Signed-off-by: Adrian Hunter Cc: Andi Kleen Cc: Jiri Olsa Link: https://lore.kernel.org/r/20210530192308.7382-13-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf scripting python: Add perf_sample_srcline() and perf_sample_srccode()

2021-06-01T13:04:35+00:00

Add perf_sample_srcline() and perf_sample_srccode() to the perf_trace_context module so that a script can get the srcline or srccode information.

perf scripting python: Add perf_set_itrace_options()

2021-06-01T13:04:24+00:00

Add perf_set_itrace_options() to the perf_trace_context module so that a script can set the itrace options for a session if they have not been set already.

perf scripting python: Add perf_sample_insn()

2021-06-01T13:03:58+00:00

Add perf_sample_insn() to the perf_trace_context module so that a script can get the instruction bytes. Signed-off-by: Adrian Hunter Cc: Andi Kleen Cc: Jiri Olsa Link: https://lore.kernel.org/r/20210530192308.7382-8-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf scripting python: Assign perf_script_context

2021-06-01T13:03:33+00:00

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.

perf scripting python: Simplify perf-trace-context module functions

2021-06-01T13:02:47+00:00

Simplify perf-trace-context module functions by factoring out some common code. Signed-off-by: Adrian Hunter Cc: Andi Kleen Cc: Jiri Olsa Link: https://lore.kernel.org/r/20210530192308.7382-3-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf scripting python: Remove unnecessary 'static'

2021-06-01T13:02:25+00:00

The variables are always assigned before use, making the 'static' storage class unnecessary. Signed-off-by: Adrian Hunter Cc: Arnaldo Carvalho de Melo Cc: Andi Kleen Cc: Jiri Olsa Link: https://lore.kernel.org/r/20210530192308.7382-2-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf scripts python: intel-pt-events.py: Add branches to script

2021-05-25T13:07:17+00:00

As an example, add branch information to intel-pt-events.py script. This shows how a simple python script can be used to customize perf script output for Intel PT branch traces or power event traces.

perf scripts python: exported-sql-viewer.py: Fix warning display

2021-05-21T19:31:07+00:00

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.
