Subject: [dpdk-dev] [PATCH v5 8/9] app/test: add dmadev fill tests
Date: Fri, 17 Sep 2021 14:54:28 +0100	[thread overview]
Message-ID: <20210917135429.90562-9-bruce.richardson@intel.com> (raw)
In-Reply-To: <20210917135429.90562-1-bruce.richardson@intel.com>

From: Kevin Laatz <kevin.laatz@intel.com>

For dma devices which support the fill operation, run unit tests to
verify fill behaviour is correct.
