From: Chas Williams <ch...@att.com>The IOMMU in some machines report that they can only support limited widths. IOVA virtual addresses may exceed this width making the use of IOVA virtual addresses difficult. The option CONFIG_RTE_LIBRTE_USE_PHYS_IOVA can used to force IOVA physical address usage.
Is it possible to dynamically detect the machine limitation in bus iova code instead of compile time option?
