perf script python: Add Python3 support to sctop.py Support both Python2 and Python3 in the sctop.py script There may be differences in the ordering of output lines due to differences in dictionary ordering etc. However the format within lines should be unchanged. The use of 'from __future__' implies the minimum supported Python2 version is now v2.6 Signed-off-by: Tony Jones <[email protected]> Cc: Tom Zanussi <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Seeteena Thoufeek <[email protected]> Signed-off-by: Arnaldo Carvalho de Melo <[email protected]> --- tools/perf/scripts/python/sctop.py | 24 ++++++++++++++++-------- 1 file changed, 16 insertions(+), 8 deletions(-) diff --git a/tools/perf/scripts/python/sctop.py b/tools/perf/scripts/python/sctop.py index 61621b93affb..987ffae7c8ca 100644 --- a/tools/perf/scripts/python/sctop.py +++ b/tools/perf/scripts/python/sctop.py @@ -8,7 +8,14 @@ # will be refreshed every [interval] seconds.
