From e26e63be64a108c1fd12020b93b5b447ffe0532b Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Tue, 12 Jul 2016 19:05:56 +0900 Subject: perf build: Add sdt feature detection This checks whether sys/sdt.h is available or not, which is required for DTRACE_PROBE(). We can disable this feature by passing NO_SDT=1 when building. This flag will be used for SDT test case and further SDT events in perftools.
