Subject: [kvm-unit-tests PATCH v4 02/12] arm: pmu: Let pmu tests take a sub-test parameter
Date: Fri, 3 Apr 2020 09:13:16 +0200 [thread overview]
Message-ID: <20200403071326.29932-3-eric.auger@redhat.com> (raw)
In-Reply-To: <20200403071326.29932-1-eric.auger@redhat.com>
As we intend to introduce more PMU tests, let's add
a sub-test parameter that will allow to categorize
them. Existing tests are in the cycle-counter category.
Signed-off-by: Eric Auger <eric.auger@redhat.com>
