Subject: [PATCH 5/6] selftests: arm64: Add wrapper scripts for stress tests
Date: Thu, 30 Jul 2020 19:09:19 +0100
Message-ID: <20200730180920.23527-6-broonie@kernel.org> (raw)
In-Reply-To: <20200730180920.23527-1-broonie@kernel.org>

Add wrapper scripts which invoke fpsimd-test and sve-test with several
copies per CPU such that the context switch code will be appropriately
exercised.
