Hi Thomas,

quoted

+#if LINUX_VERSION_CODE < KERNEL_VERSION(4, 5, 0)

Why not #ifndef VFIO_NOIOMMU_IOMMU?
It would avoid some backport issue.

I don't see how it could. Versions post-4.5 will have VFIO_NOIOMMU_IOMMU, so no issue there. Pre-4.5 versions, whether they do or do not have VFIO_NOIOMMU_IOMMU defined, will have RTE_VFIO_NOIOMMU defined as 8 regardless.

Thanks,
Anatoly
