tools: Adopt __noreturn from kernel sources

2017-06-19T18:14:58+00:00

To have a more compact way to specify that a function doesn't return,
instead of the open coded:

	__attribute__((noreturn))

And use it instead of the tools/perf/ specific variation, NORETURN.

perf tools: Simplify die() mechanism

2016-03-23T15:32:31+00:00

This should die altogether, but for now lets remove a bit of this stuff,
as it is not used at all.

perf test: Suppress libtraceevent warnings

2015-10-19T17:58:10+00:00

Currently libtraceevent emits warning on unsupported event formats.
However it'd be better to see them only -v option is given.  To do that,
it needs to override the warning() function which is used in the
libtracevent.  Thus add set_warning_routine() same as set_die_routine()
and check the verbose flag in our warning routine.

Before:
  # perf test 5
   5: parse events tests                                       :
    Warning: [kvmmmu:kvm_mmu_get_page] bad op token {
    Warning: [kvmmmu:kvm_mmu_sync_page] bad op token {
    Warning: [kvmmmu:kvm_mmu_unsync_page] bad op token {
    Warning: [kvmmmu:kvm_mmu_prepare_zap_page] bad op token {
    Warning: [kvmmmu:fast_page_fault] function is_writable_pte not defined
    ...
   Ok

After:
  # perf test 5
   5: parse events tests                                       : Ok

Add and use the modern perf_target__parse_uid() and get rid of the old

perf target: Split out perf_target handling code

2012-05-02T18:41:11+00:00

For further work on perf_target, it'd be better off splitting the code
into a separate file.

perf tools: Check more combinations of PID/TID, UID and CPU switches

2012-05-02T18:24:14+00:00

There were some combinations of these switches that are not so
appropriate IMHO.

Since there are implicit priorities between them and they worked well
anyway, but it ends up opening useless duplicated events.

For example, 'perf stat -t  -a' will open multiple events for the
thread instead of one.

Add explicit checks and warn user in perf_target__validate().

perf tools: Introduce perf_target__validate() helper

2012-05-02T18:22:08+00:00

The perf_target__validate function is used to check given PID/TID/UID/CPU
target options and warn if some combination is impossible. Also this can
make some arguments of parse_target_uid() function useless as it is checked
before the call via our new helper.
