From: Tony Jones Date: Fri, 22 Feb 2019 15:06:16 -0800 Subject: perf script python: Add Python3 support to stat-cpi.py Origin: https://git.kernel.org/linus/e985bf761db7646cebcd236249da08bd264069de Bug-Debian: https://bugs.debian.org/944641 Support both Python2 and Python3 in the stat-cpi.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: Seeteena Thoufeek Cc: Jiri Olsa Link: http://lkml.kernel.org/r/20190222230619.17887-13-tonyj@suse.de Signed-off-by: Tony Jones Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/scripts/python/stat-cpi.py | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) --- a/tools/perf/scripts/python/stat-cpi.py +++ b/tools/perf/scripts/python/stat-cpi.py @@ -1,6 +1,8 @@ #!/usr/bin/env python # SPDX-License-Identifier: GPL-2.0 +from __future__ import print_function + data = {} times = [] threads = [] @@ -20,8 +22,8 @@ def store_key(time, cpu, thread): threads.append(thread) def store(time, event, cpu, thread, val, ena, run): - #print "event %s cpu %d, thread %d, time %d, val %d, ena %d, run %d" % \ - # (event, cpu, thread, time, val, ena, run) + #print("event %s cpu %d, thread %d, time %d, val %d, ena %d, run %d" % + # (event, cpu, thread, time, val, ena, run)) store_key(time, cpu, thread) key = get_key(time, event, cpu, thread) @@ -59,7 +61,7 @@ def stat__interval(time): if ins != 0: cpi = cyc/float(ins) - print "%15f: cpu %d, thread %d -> cpi %f (%d/%d)" % (time/(float(1000000000)), cpu, thread, cpi, cyc, ins) + print("%15f: cpu %d, thread %d -> cpi %f (%d/%d)" % (time/(float(1000000000)), cpu, thread, cpi, cyc, ins)) def trace_end(): pass @@ -75,4 +77,4 @@ def trace_end(): # if ins != 0: # cpi = cyc/float(ins) # -# print "time %.9f, cpu %d, thread %d -> cpi %f" % (time/(float(1000000000)), cpu, thread, cpi) +# print("time %.9f, cpu %d, thread %d -> cpi %f" % (time/(float(1000000000)), cpu, thread, cpi))
