Subject: Re: [PATCH v7 4/9] vfio/pci: Add a helper to look up PFNs for DMABUFs
Date: Thu, 24 Sep 2026 15:35:07 +0000 [thread overview]
Message-ID: <20260924153507.EDA0D1F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260924152159.49702-5-matt@ozlabs.org>
> Add vfio_pci_dma_buf_find_pfn(), which a VMA fault handler can use to
> find a PFN.
>
> This supports multi-range DMABUFs, which typically would be used to
> represent scattered spans but might even represent overlapping or
> aliasing spans of PFNs.
>
> Because this is intended to be used in vfio_pci_core.c, we also need
> to expose the struct vfio_pci_dma_buf in the vfio_pci_priv.h header.
>
> This move also adds a new member, vma_pgoff_adjust; this is consumed
> by vfio_pci_dma_buf_find_pfn(), but will be set in a future commit.
> Add it now to reduce the number of functions touched by later commits.
>
> Signed-off-by: Matt Evans <matt@ozlabs.org>
