perf test: Fix hists related entries
That got broken by d3a72fd8187b ("perf report: Fix indentation of dynamic entries in hierarchy"), by using the evlist in setup_sorting() without checking if it is NULL, as done in some 'perf test' entries: $ find tools/ -name "*.c" | xargs grep 'setup_sorting(NULL);' tools/perf/tests/hists_output.c: setup_sorting(NULL); tools/perf/tests/hists_output.c: setup_sorting(NULL); tools/perf/tests/hists_output.c: setup_sorting(NULL); tools/perf/tests/hists_output.c: setup_sorting(NULL); tools/perf/tests/hists_output.c: setup_sorting(NULL); tools/perf/tests/hists_cumulate.c: setup_sorting(NULL); tools/perf/tests/hists_cumulate.c: setup_sorting(NULL); tools/perf/tests/hists_cumulate.c: setup_sorting(NULL); tools/perf/tests/hists_cumulate.c: setup_sorting(NULL); $ Fix it. Before: [root@jouet ~]# perf test <SNIP> 15: Test matching and linking multiple hists : FAILED! 16: Try 'import perf' in python, checking link problems : Ok 17: Test breakpoint overflow signal handler : Ok 18: Test breakpoint overflow sampling : Ok 19: Test number of exit event of a simple workload : Ok 20: Test software clock events have valid period values : Ok 21: Test object code reading : Ok 22: Test sample parsing : Ok 23: Test using a dummy software event to keep tracking : Ok 24: Test parsing with no sample_id_all bit set : Ok 25: Test filtering hist entries : FAILED! 26: Test mmap thread lookup : Ok 27: Test thread mg sharing : Ok 28: Test output sorting of hist entries : FAILED! 29: Test cumulation of child hist entries : FAILED! <SNIP> After the patch the above failed tests complete successfully.
