Subject: [kvm-unit-tests PATCH v3 02/10] arm64: microbench: Generalize ipi test names
Date: Fri, 31 Jul 2020 15:42:36 +0800
Message-ID: <20200731074244.20432-3-wangjingyi11@huawei.com> (raw)
In-Reply-To: <20200731074244.20432-1-wangjingyi11@huawei.com>

Later patches will use these functions for gic(ipi/lpi/timer) tests.
