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

DESCRIPTION

-----------

This command does assorted sanity tests, initially through linked routines but
|

also will look for a directory with more tests in the form of scripts.

To get a list of available tests use 'perf test list', specifying a test name
|
|
fragment will show all tests that have it.
|
|
|
|
To run just specific tests, inform test name fragments or the numbers obtained
|
|
from 'perf test list'.
