Subject: [PATCH v2 10/16] dmaengine: idxd: add descs_completed field for completion record
Date: Mon, 6 Mar 2023 08:31:32 -0800 [thread overview]
Message-ID: <20230306163138.587484-11-fenghua.yu@intel.com> (raw)
In-Reply-To: <20230306163138.587484-1-fenghua.yu@intel.com>
From: Dave Jiang <dave.jiang@intel.com>
The descs_completed field for a completion record is part of a batch
descriptor completion record. It takes the same location as bytes_completed
in a normal descriptor field. Add to expose to user.
