Subject: [kvm-unit-tests PATCH v2 2/9] arm: pmu: Let pmu tests take a sub-test parameter
Date: Thu, 30 Jan 2020 12:25:03 +0100
Message-ID: <20200130112510.15154-3-eric.auger@redhat.com> (raw)
In-Reply-To: <20200130112510.15154-1-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.
