Subject: [PATCH v2 3/5] perf test: Ensure sample_period is set libpfm4 events
Date: Tue, 28 Jul 2020 01:57:32 -0700	[thread overview]
Message-ID: <20200728085734.609930-4-irogers@google.com> (raw)
In-Reply-To: <20200728085734.609930-1-irogers@google.com>

Test that a command line option doesn't override the period set on a
libpfm4 event.
Without libpfm4 test passes as unsupported.
