DPDK does not differentiate physical and virtual IO addresses and always refers them as IOVA even if no IO memory management unit (IOMMU) is involved in VA. IOVA modes are special cases : | Physical Address Mode (PA) | Virtual Address Mode (VA) | | ------------------------------------------------------------------------ | ----------------------------------------------------------------------- | | IOVA address are assigned to all DPDK memory are actual physical address | The physical memory layout is reshuffled to match virtual memory layout | | Does not require IOMMU to work | Uses IOMMU to remap physical memory | | Works well with kernel space (physical address => kernel address) | Memory is IOVA contiguous | | PA mode is *default* | Preferable for emulated environments | **How to set** ```cmake= ./app --iova-mode=pa # use IOVA as PA mode ./app --iova-mode=va # use IOVA as VA mode ``` ### Debug attempt ![](https://i.imgur.com/f5OFnbm.png) :::spoiler build results :::warning ```=shell [oai@ee705-7-ip120 fhi_lib]$ ./build.sh Number of commandline arguments: 0 MLOG folder is not set.
