Subject: [PATCH v13 08/15] vfio: Introduce a vfio_dma type field
Date: Thu, 6 Oct 2016 08:45:24 +0000 [thread overview]
Message-ID: <1475743531-4780-9-git-send-email-eric.auger@redhat.com> (raw)
In-Reply-To: <1475743531-4780-1-git-send-email-eric.auger@redhat.com>
We introduce a vfio_dma type since we will need to discriminate
different types of dma slots:
- VFIO_IOVA_USER: IOVA region used to map user vaddr
- VFIO_IOVA_RESERVED_MSI: IOVA region reserved to map MSI doorbells
Signed-off-by: Eric Auger <eric.auger@redhat.com>
---
v9 -> v10:
- renamed VFIO_IOVA_RESERVED into VFIO_IOVA_RESERVED_MSI
- explicitly set type to VFIO_IOVA_USER on dma_map
v6 -> v7:
- add VFIO_IOVA_ANY
- do not introduce yet any VFIO_IOVA_RESERVED handling
