DPDK (Data Plane Development Kit) is a set of libraries
|
|
and drivers for fast packet processing.

http://dpdk.org/
|
|
|
|
Optional but recommended kernel configurations:
|
|
- CONFIG_VFIO_IOMMU_TYPE1
|
|
- CONFIG_VFIO_VIRQFD
|
|
- CONFIG_VFIO
|
|
- CONFIG_VFIO_NOIOMMU
|
|
- CONFIG_VFIO_PCI
|
|
- CONFIG_VFIO_PCI_MMAP
|
|
- CONFIG_HUGETLBFS
|
|
- CONFIG_HUGETLB_PAGE
|
|
- CONFIG_PROC_PAGE_MONITOR
|
|
|

For x86 only, the following can also be useful:
|

- CONFIG_HPET

- CONFIG_HPET_MMAP

Controls which DPDK drivers are built.

none : build no drivers

dependencies in this list, and/or select the relevant

configuration will fail in case of missing dependencies.
