Do you have any suggestion @pprindeville ?

cross-compile for arm status 2024

Hi,

Has this code been tested on arm?

I'm trying to cross-compile for MT7986(Filogic 830).

The master returns this:
Problem encountered: Arm SoC must be specified in the cross file.

Devel returns this:

kmod intel iommu ?

可否增加intel iommu MAKEFILE 呢？我不知道怎么改你现有的AMD iommu MAKEFILE
kmod-vfio-pci、 kmod-uio_pci_generic有了，貌似不需要考虑HUGETLB？

https://doc.dpdk.org/guides/howto/openwrt.html
12.2.2. Kernel configuration
The following configurations should be enabled:

CONFIG_VFIO_IOMMU_TYPE1=y
CONFIG_VFIO_VIRQFD=y
CONFIG_VFIO=y
CONFIG_VFIO_NOIOMMU=y
CONFIG_VFIO_PCI=y
CONFIG_VFIO_PCI_MMAP=y
CONFIG_HUGETLBFS=y

CONFIG_PROC_PAGE_MONITOR=y

cross compile for arm64 failed

error log
../../build_dir/target-aarch64_generic_musl/dpdk-22.03/config/arm/meson.build:484:12: ERROR: Problem encountered: Arm SoC must be specified in the cross file.

need change MESON_CPU value Makefile? my cpu is RK3399, use this value failed, What value shoud I use?

请问openwrt 23.05 x86版能用吗？

Cross-compilation for DPDK with ARM-based OpenWrt

This repository is prepared for DPDK and OpenWrt in x86_64-based environment. I am building OpenWrt for the ARM target on a x86_64 machine using Ubuntu, and I am currently using the build on a ARM-based device but I would like to enable DPDK on it. Do you plan to provide ARM option? If the answer is no, do you have any suggestions about the required modifications to this repository?
