Subject: [PATCH 03/12] mtip32xx: don't use block layer bounce buffers
Date: Mon, 16 Apr 2018 10:50:23 +0200 [thread overview]
Message-ID: <20180416085032.7367-4-hch@lst.de> (raw)
In-Reply-To: <20180416085032.7367-1-hch-jcswGhMUV9g@public.gmane.org>
mtip32xx just sets the block bounce limit to the dma mask, which means
that the iommu or swiotlb already take care of the bounce buffering,
and the block bouncing can be removed.
