From: Jiri Olsa <jo...@redhat.com> The following tests are failing on powerpc:
# perf test break 18: Breakpoint overflow signal handler : FAILED! 19: Breakpoint overflow sampling : FAILED! The powerpc kenel so far does not have support to even create instruction breakpoints using the perf event interface, so those tests fail early in the config phase. I added a '->is_supported()' callback to test struct to be able to disable specific tests. It seems better than putting ifdefs directly to the test array.
