Subject: [dpdk-dev] [PATCH v26 5/6] dma/skeleton: introduce skeleton dmadev driver
Date: Wed, 13 Oct 2021 20:24:59 +0800	[thread overview]
Message-ID: <20211013122500.51552-6-fengchengwen@huawei.com> (raw)
In-Reply-To: <20211013122500.51552-1-fengchengwen@huawei.com>

Skeleton dmadevice driver, on the lines of rawdev skeleton, is for
showcasing of the dmadev library.

Design of skeleton involves a virtual device which is plugged into VDEV
bus on initialization.

Also, enable compilation of dmadev skeleton drivers.
