Subject: [PATCH 10/26] dma-buf: Convert all the simple exporters to use SGT mapping type
Date: Mon, 26 Oct 2026 16:36:01 +1100 [thread overview]
Message-ID: <20261026053623.202642-11-apopple@nvidia.com> (raw)
In-Reply-To: <20261026053623.202642-1-apopple@nvidia.com>
From: Jason Gunthorpe <jgg@nvidia.com>
Update the exporters to use a SGT mapping type and the new style mapping
type API. None of these exporters do anything with attach->peer2peer or
importer_ops->allow_peer2peer and they all follow the same pattern.
Change all the places that need to get the SGT's DMA device for DMA API
use to use dma_buf_sgt_dma_device().
This is all a mechanical change of moving the map_dma_buf/unmap_dma_buf
into DMA_BUF_SIMPLE_SGT_EXP_MATCH() arguments and switching
attach->dev to dma_buf_sgt_dma_device(attach).
