perf scripts python: exported-sql-viewer.py: Fix python3 support

2019-03-28T18:53:16Z

Unlike python2, python3 strings are not compatible with byte strings. That results in disassembly not working for the branches reports. Fixup those places overlooked in the port to python3.

perf scripts python: exported-sql-viewer.py: Fix never-ending loop

2019-03-28T17:41:21Z

pyside version 1 fails to handle python3 large integers in some cases, resulting in Qt getting into a never-ending loop. This affects: samples Table samples_view Table All branches Report Selected branches Report Add workarounds for those cases.

perf script python: Add Python3 support to exported-sql-viewer.py

2019-03-11T19:12:52Z

Support both Python2 and Python3 in the exported-sql-viewer.py script. The use of 'from __future__' implies the minimum supported Python2 version is now v2.6 Signed-off-by: Tony Jones Acked-by: Adrian Hunter Link: http://lkml.kernel.org/r/20190309000518.2438-2-tonyj@suse.de Signed-off-by: Seeteena Thoufeek Signed-off-by: Arnaldo Carvalho de Melo

perf scripts python: exported-sql-viewer.py: Add call tree

2019-03-01T18:04:16Z

Add a new report to display a call tree. The Call Tree report is very similar to the Context-Sensitive Call Graph, but the data is not aggregated. Also the 'Count' column, which would be always 1, is replaced by the 'Call Time'.

2019-02-22T19:52:07Z

If no selection is made on the 'Selected branches' dialog, then the output is the same as the 'All branches' report. That is not really an error, and is not desirable for future reports, so remove it. Signed-off-by: Adrian Hunter Cc: Jiri Olsa Signed-off-by: Arnaldo Carvalho de Melo
