[kvm-unit-tests PATCH 02/10] arm: pmu: Let pmu tests take a sub-test parameter

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
