STRUCT VFIO_IOMMU_DRIVER_OPS(9)

Hiii bestie 💖 welcome to the Kernel API Manual page for struct vfio_iommu_driver_ops(9) — the VFIO IOMMU driver callbacks one. This is the whole tea, no cap. 🫶

✨ NAME ✨

It’s called struct vfio_iommu_driver_ops — VFIO IOMMU driver callbacks. That’s the vibe. 💅

✨ SYNOPSIS ✨

Okay so the whole struct is literally right here, bestie — every field, exactly as the page gives it:

       struct vfio_iommu_driver_ops {
           char *name;
           struct module   *owner;
           void *(*open)(unsigned long arg);
           void (*release)(void *iommu_data);
           long (*ioctl)(void *iommu_data, unsigned int cmd, unsigned long
       arg);
           int (*attach_group)(void *iommu_data, struct iommu_group *group,
       enum vfio_group_type);
           void (*detach_group)(void *iommu_data, struct iommu_group *group);
           int (*pin_pages)(void *iommu_data, struct iommu_group *group,
       dma_addr_t user_iova, int npage, int prot, struct page **pages);
           void (*unpin_pages)(void *iommu_data, dma_addr_t user_iova, int
       npage);
           void (*register_device)(void *iommu_data, struct vfio_device *vdev);
           void (*unregister_device)(void *iommu_data, struct vfio_device
       *vdev);
           int (*dma_rw)(void *iommu_data, dma_addr_t user_iova, void *data,
       size_t count, bool write);
           struct iommu_domain *(*group_iommu_domain)(void *iommu_data, struct
       iommu_group *group);
        };

💅 Members 💅

The original page hits us with the Members heading and then… nothing else. Literally a cliffhanger. 😭 No member-by-member breakdown on this page — the members are the fields up in the struct, and that’s the whole thing. 🫶

🌈 SEE ALSO 🌈

• Kernel file: ./drivers/vfio/vfio.h — that’s the one it points you to. 👑

okay bye bestie 🎀 this page is from ./drivers/vfio, dated October 2026, and the footer title is literally struct vfio_...u_driver_ops(9) — periodt. 💜
