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.
