+in either DPU mode or separated host mode.

 ## Prerequisites
 
 - Linux (with kernel >= 4.4) or FreeBSD
 - For Linux, glibc >= 2.7 (reported by `ldd --version`)
 - GCC >= 9 (C++17 compliant compiler)
 - [DPDK](https://github.com/DPDK/dpdk) >= v21.11 (can be installed via vcpkg)
-- [Apache Arrow](https://github.com/apache/arrow) >= 7.0.0 (build automatically

   There is no such problem when DPDK is compiled with GCC. Note that bitar can
   still be compiled with Clang and linked with DPDK that is compiled with GCC.

+  (Aug 18, 2022) If you see this error, check whether DPDK is running in the
+  Virtual Addresses mode (VA). Normally, you should see
+  `EAL: Selected IOVA mode 'VA'` during the program initialization. But if you
+  see `EAL: Selected IOVA mode 'PA'`, it's probably that the IOMMU is disable

+  `/sys/kernel/iommu_groups` path will contain kernel IOMMU groups and thus is
+  not be empty. To enable IOMMU in the kernel, you can add
+  `intel_iommu=on iommu=pt` in GRUB command-line on x86_64 systems, or add
+  `iommu.passthrough=1` on aarch64 systems.
