DPDK enables direct packet steering from some network interfaces to the userland, bypassing the Linux kernel network stack. This is achieved through userland PCI drivers or by leveraging some userland memory mappings of the network devices. Originally inspired by RDMA (Remote Direct Memory Access) concepts, DPDK has been adapted to work with PCI devices that do not inherently support RDMA. This adaptation allows for low-latency, high-throughput data processing by minimizing the overhead typically associated with kernel-space network drivers. Importantly, this commit does not enforce the use of UIO or VFIO kernel frameworks, as DPDK's architecture supports userland memory mappings that do not require these technologies. By maintaining this flexibility, DPDK can operate with a broader range of hardware and software configurations, making it suitable for diverse Buildroot's deployment scenarios. Yocto patch imported from: https://git.yoctoproject.org/meta-dpdk/plain/recipes-extended/dpdk/dpdk/0001-config-meson-get-cpu_instruction_set-from-meson-opti.patch Only the little endian targets are properly supported by DPDK. Big endian was supported, mostly on Power8, but it has not been used for a while and IBM is not strongly pushing any tests. Should big endian be supported again, DPDK community will be welcoming any contributions. Some nice to have for the Kernel, but not mandatory: - 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_HUGETLB_PAGE=y - CONFIG_PROC_PAGE_MONITOR=y For x86 only, HPET and HPET_MMAP can be some nice to have too. Since they are some nice to have, but not mandatory ones, the following Kernel config fixups are not used: define DPDK_LINUX_CONFIG_FIXUPS $(call KCONFIG_ENABLE_OPT, CONFIG_HUGETLBFS) ... endef Notes about license: DPDK was released with the BSD-3-Clause license. One network driver, the Google Virtual Ethernet (GVE) include files under the MIT license. See [2] and [3]. DPDK had been including a Kernel Netdevice Interface (KNI) and an IGB_UIO kernel module under the GPL-2.0 license. Those modules were moved into a different repository [K]. Then, for instance, the KNI module was removed by [KNI]. This commit was first included in version v23.11. The IGB_UIO kernel module was removed by [UIO] since VFIO became capable of supporting all the required usecases for the DPDK. The main remaining issues had been the support of memory mapping within a VM or without the use of nested virtualization but those were fixed by the latest VFIO's kernel support. We can notice that the PMD drivers that are using the ibverbs (RDMA) APIs are not sharing this need of UIO/VFIO. There are also 2 files in "lib/eal/windows" under other licenses (namely BSD-2-Clause, ISC and MIT) but they are parts of the Environment Abstraction Library (EAL) for Microsoft Windows OS, it means they are not used when compiling for the Linux targets of Buildroot. The list of DPDK license exceptions is maintained at [3].
