Subject: [PATCH 07/14] perf test: Add memcpy thread test tool
Date: Tue, 12 Jul 2022 14:57:43 +0100 [thread overview]
Message-ID: <20220712135750.2212005-8-carsten.haitzler@foss.arm.com> (raw)
In-Reply-To: <20220712135750.2212005-1-carsten.haitzler@foss.arm.com>
From: "Carsten Haitzler (Rasterman)" <raster@rasterman.com>
Add test tool to be driven by further test scripts. This is a simple C
based memcpy with threads test to drive from scripts.
