	This patch changes how test output is printed out. By default, if test had no errors, the only output will be a single line with test number, name, and verdict at the end, e.g.: #31 xdp:OK If test had any errors, all log output captured during test execution will be output after test completes. It's possible to force output of log with `-v` (`--verbose`) option, in which case output won't be buffered and will be output immediately. To support this, individual tests are required to use helper methods for logging: `test__printf()` and `test__vprintf()`.

2019-07-16	selftests/bpf: skip nmi test when perf hw events are disabled	Ilya Leoshkevich
	Some setups (e.g. virtual machines) might run with hardware perf events disabled. If this is the case, skip the test_send_signal_nmi test. Add a separate test involving a software perf event. This allows testing the perf event path regardless of hardware perf event support.

	The test covered both nmi and tracepoint perf events. $ ./test_progs ... test_send_signal_tracepoint:PASS:tracepoint 0 nsec ... test_send_signal_common:PASS:tracepoint 0 nsec ... test_send_signal_common:PASS:perf_event 0 nsec ... test_send_signal:OK Acked-by: Andrii Nakryiko <andriin@fb.com> Signed-off-by: Yonghong Song <yhs@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
