The purpose is to add unit tests for new features (such as lapic deadline timer). There are examples that make it relatively easy to construct new test case (or modify existing ones to accomodate new tests). Please add a new test case for lapic deadline timer, thanks. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
