Subject: [PATCH 04/15] tools build: Add jvmti feature detection support
Date: Mon, 14 Nov 2016 22:38:36 -0300 [thread overview]
Message-ID: <1479173927-24613-5-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1479173927-24613-1-git-send-email-acme@kernel.org>
From: Jiri Olsa <jolsa@kernel.org>
Adding support to detect jvmti support. It is not plugged into the
FEATURE_TESTS machinery, because it's quite rare and will be used
separately from perf via feature_check call.
