Hi Jean, vfio can be compiled as module, however you use some functions which are not exported. comment inline: [...] > Add two new ioctl for VFIO containers. VFIO_IOMMU_BIND_PROCESS creates a > bond between a container and a process address space, identified by a > device-specific ID named

[PATCH 37/37] vfio: Add support for Shared Virtual Addressing

Add two new ioctl for VFIO containers. VFIO_IOMMU_BIND_PROCESS creates a bond between a container and a process address space, identified by a device-specific ID named PASID. This allows the device to target DMA transactions at the process virtual addresses without a need for mapping and unmapping
