[Qemu-devel] [PATCH/RFC 4/5] vfio: No-IOMMU mode support

2018-02-09 Thread Geert Uytterhoeven
From: Xiao Feng Ren Add qemu support for the newly introduced VFIO No-IOMMU driver. We need to add special handling for: - Group character device is /dev/vfio/noiommu-$GROUP. - No-IOMMU does not rely on a memory listener. - No IOMMU will be set for its group, so no need to call vfio_kvm_device
