Subject: Re: [PATCH v2 05/23] dma-buf: Route SGT related actions through the attachment's mapping type
Date: Fri, 06 Nov 2026 06:43:49 +0000 [thread overview]
Message-ID: <sashiko-outbox-200921@kernel.org> (raw)
In-Reply-To: <20261105-dma_mapping_type_v4-v2-5-78b8dc9ae80a@nvidia.com>
> From: Jason Gunthorpe <jgg@nvidia.com>
>
> Now that dma_buf_dynamic_attach() ensures a mapping type exists, even for
> exporters and importers that don't provide it, route operations through
> dma_buf_attach_map_type().
>
> For map/unmap this will go through dma_buf_sgt_compat_map_dma_buf() which
> calls the same attach->dmabuf->ops->map_dma_buf().
>
> Move the debugfs processing unique to SGT into a callback too.
