Date: Fri, 27 May 2022 11:40:53 +0800 [thread overview]
Message-ID: <20220527034055.33271-3-fengchengwen@huawei.com> (raw)
In-Reply-To: <20220527034055.33271-1-fengchengwen@huawei.com>
If no DMA request is completed, the ring_idx of the last completed
operation need returned by last_idx parameter. This patch adds
testcase for it.
