From 598762cf91532e6e86dd21199b5e7f803df73f49 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 1 Jun 2017 22:54:50 +0200 Subject: perf test: Disable breakpoint signal tests for powerpc 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.
