[PATCH 00/12] perf tests: Move tests from builtin-test

[PATCH 00/12] perf tests: Move tests from builtin-test

[Jiri Olsa]

hi,
I discussed with Arnaldo of moving tests from builtin-test
into separated objects.. here it is. I swear not to touch
test code for a while after this one ;-)

Attached patches:
  01/12 perf tests: Move test__vmlinux_matches_kallsyms into separate object
  02/12 perf tests: Move test__open_syscall_event into separate object
  03/12 perf tests: Move test__open_syscall_event_on_all_cpus into separate object
  04/12 perf tests: Move test__basic_mmap into separate object
  05/12 perf tests: Move test__PERF_RECORD into separate object
  06/12 perf tests: Move test__rdpmc into separate object
  07/12 perf tests: Move perf_evsel__roundtrip_name_test into separate object
  08/12 perf tests: Move perf_evsel__tp_sched_test into separate object
  09/12 perf tests: Move test__syscall_open_tp_fields into separate object
  10/12 perf tests: Move pmu tests into separate object
  11/12 perf tests: Final cleanup for builtin-test move
  12/12 perf tests: Check for mkstemp return value in dso-data test

Also available here:

thanks,
jirka

[PATCH 02/12] perf tests: Move test__open_syscall_event into separate object

[Jiri Olsa]

Separating test__open_syscall_event test from
the builtin-test into open-syscall object.

Adding util object under tests directory to gather
help functions common to more tests.

perf tests: Move test__open_syscall_event into separate object

Separating test__open_syscall_event test from the builtin-test into
open-syscall object.

Adding util object under tests directory to gather help functions common
to more tests.
