Subject: RE: [PATCH v2 1/6] dma/ioat: fix device stop if no copies done
Date: Wed, 18 Jan 2023 10:47:11 +0000 [thread overview]
Message-ID: <PH0PR11MB52079B23C3A2AFD087897F72FFC79@PH0PR11MB5207.namprd11.prod.outlook.com> (raw)
In-Reply-To: <20230116173738.562322-2-bruce.richardson@intel.com>
> The HW DMA devices supported by IOAT driver do not transition to
> the "active" state until the first operation is started by the HW.
> Therefore, if the user calls "rte_dma_stop()" on a device without
> triggering any operations, the sequence of commands to be sent to
> the HW is different, as is the final device state.
>
> Update the IOAT driver "stop" function to take account of this
> difference.
