}

VFIO_IOMMU_SPAPR_REGISTER_MEMORY - _IOW(VFIO_TYPE, VFIO_BASE + 17, struct vfio_iommu_spapr_register_memory)

Registers user space memory where DMA is allowed. It pins user pages and does the locked memory accounting so subsequent VFIO_IOMMU_MAP_DMA/VFIO_IOMMU_UNMAP_DMA calls get faster.

Fields

argsz: __u32

flags: __u32

vaddr: __u64

size: __u64
