Sometimes a test is problematic for some reason and one wants to skip it, for instance: [root@sandy ~]# perf test 1: vmlinux symtab matches kallsyms : Ok 2: detect open syscall event : Ok 3: detect open syscall event on all cpus : Ok 4: read samples using the mmap interface : Ok 5: parse events tests : Warning: bad op token { Warning: bad op token { Warning: bad op token { Warning: bad op token { Warning: bad op token { Warning: function is_writable_pte not defined Segmentation fault (core dumped) So now we can use -s/--skip while the problematic tests are being fixed, allowing us to test all the other entries: [root@sandy ~]# perf test -s 5 1: vmlinux symtab matches kallsyms : Ok 2: detect open syscall event : Ok 3: detect open syscall event on all cpus : Ok 4: read samples using the mmap interface : Ok 5: parse events tests : Skip (user override) 6: x86 rdpmc test : Ok 7: Validate PERF_RECORD_* events & perf_sample fields : Ok 8: Test perf pmu format parsing : Ok 9: Test dso data interface : Ok 10: roundtrip evsel->name check : Ok 11: Check parsing of sched tracepoints fields : Ok 12: Generate and check syscalls:sys_enter_open event fields: Ok 13: struct perf_event_attr setup : Ok 14: Test matching and linking mutliple hists : Ok 15: Try 'use perf' in python, checking link problems : Ok [root@sandy ~]# Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-klzd8p57jzdryafqkmlppcb1@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
