This patch implements initial support for Single Root I/O Virtualization on an NVMe device. Essentially, it allows to define the maximum number of virtual functions supported by the NVMe controller via sriov_max_vfs parameter. Passing a non-zero value to sriov_max_vfs triggers reporting of SR-IOV capability by a physical controller and ARI capability by both the physical and virtual function devices. NVMe controllers created via virtual functions mirror functionally the physical controller, which may not entirely be the case, thus consideration would be needed on the way to limit the capabilities of the VF. NVMe subsystem is required for the use of SR-IOV. Signed-off-by: Lukasz Maniak <lukasz.maniak@linux.intel.com> Reviewed-by: Klaus Jensen <k.jensen@samsung.com> Acked-by: Michael S.
