Hi Vincent, Thank you for your patch. I am personally interested to see DPDK entering in Buildroot! Please see my comments below.

I know DPDK has some requirements/restrictions on supported architectures. For example, version 17.08 raised the minimal x86 requirement to have SSE4.2. See: https://doc.dpdk.org/guides-17.08/rel_notes/release_17_08.html So we should have something like: config BR2_PACKAGE_DPDK_ARCH_SUPPORTS bool default y if BR2_RISCV_64 default y if BR2_aarch64 || BR2_aarch64_be default y if BR2_powerpc64le # DPDK requires SSE4.2 for x86_64 since v17.08 default y if BR2_x86_64 && BR2_X86_CPU_HAS_SSE42 there is possibly other supported architectures...

The DPDK core libraries are now mostly BSD-3-Clause. The code base has some specific parts under other licenses. Maybe we should identify which license apply to which part. For example: DPDK_LICENSE = \ BSD-3-Clause (core libraries), \ MIT (drivers/net/gve/base/*) Also, the ISC and BSD-2-Clause is used in a Windows-only abstraction layer. See: https://github.com/DPDK/dpdk/blob/v24.07/lib/eal/windows/getopt.c There is also some Freescale/NXP drivers (dpaa) which are dual licensed under (BSD-3-Clause or GPL-2.0), that could be identified. Maybe this is a question to Buildroot maintainers: should we list here licenses of code which are known to be unused, such as this Windows abstraction layer? The DPDK components and licenses can be checked in its git repository, with the command: git grep -F SPDX-License-Identifier: Since DPDK has a somewhat "complex" licensing and history, an explanation could be added in the commit log. For example: Notes about license: DPDK is now mainly under the BSD-3-Clause license. One network driver, the Google Virtual Ethernet (GVE) include files under the MIT license. See [2] and [3]. DPDK used to include a Kernel NIC Interface (KNI) kernel module in GPL-2.0 license. This module was removed in commit [4]. This commit was first included in version v23.11. There is also few files in "lib/eal/windows" under other licenses (namely BSD-2-Clause, ISC and MIT) but are parts of the Environment Abstraction Library (EAL) for Microsoft Windows OS, not used when compiling for Linux in Buildroot. The list of dpdk license exceptions is maintained at [3].

I believe only host-python-pyelftools is really a mandatory dependency and all other are optional. Mandatory dependency can be listed with an assignment such as: DPDK_DEPENDENCIES = \ mandatory_dependency1 \ mandatory_dependency2 While optional dependencies can be added with something like: ifeq ($(BR2_PACKAGE_OPTIONAL_DEPENDENCY),y) DPDK_CONF_OPTS += -DOPTIONAL_DEPENDENCY=true DPDK_DEPENDENCIES += optional-dependency else DPDK_CONF_OPTS += -DOPTIONAL_DEPENDENCY=false endif See the meson example in: https://nightly.buildroot.org/manual.html#_infrastructure_for_meson_based_packages Looking at the Meson file, I think the optional Buildroot package dependencies are: dtc jansson libarchive libbpf libpcap numactl openssl rdma-core zlib > + > +ifeq ($(BR2_TOOLCHAIN_USES_GLIBC),) > +DPDK_DEPENDENCIES += libexecinfo > +endif > + > +DPDK_CONF_OPTS += -Dcpu_instruction_set=$(BR2_GCC_TARGET_ARCH) > +#DPDK_CONF_OPTS += -Dplatform=generic Is this comment intended? If yes, please remove the line. I don't know if it is related, but last time I had to use dpdk-24.03 in Buildroot, I had to define the platform in a Meson extra property such as: DPDK_MESON_EXTRA_PROPERTIES = platform='generic' Could you check if this platform definition is needed? > + Finally, DPDK core has a strong requirement on Kernel having CONFIG_HUGETLBFS enabled.

Done: I have added the Buildroot's `Upstream` tag too. I do not want to drop the Yocto's one in order to link it from Yocto too.
