perf test: Allow running just a subset of the available tests
To obtain a list of available tests:
[root@emilia linux]# perf test list
1: vmlinux symtab matches kallsyms
2: detect open syscall event
3: detect open syscall event on all cpus
4: read samples using the mmap interface
5: parse events tests
[root@emilia linux]#
To list just a subset:
[root@emilia linux]# perf test list syscall
2: detect open syscall event
3: detect open syscall event on all cpus
[root@emilia linux]#
To run a subset:
[root@emilia linux]# perf test detect
2: detect open syscall event: Ok
3: detect open syscall event on all cpus: Ok
[root@emilia linux]#
Specific tests can be chosen by number:
[root@emilia linux]# perf test 1 3 parse
1: vmlinux symtab matches kallsyms: Ok
3: detect open syscall event on all cpus: Ok
5: parse events tests: Ok
[root@emilia linux]#
Now to write more tests!
