The Intel(R) DPDK requires two kernel modules to be loaded in order to run.
|
|
To load these modules add loading lines to /boot/loader.conf
|
|
|
|
contigmem_load="YES"
|
|
nic_uio_load="YES"
|
|
|
|
The modules each take a number of parameters. These should be set in loader.conf
|
|
before the above two lines to load the module.
|
|
|
|
* The "contigmem" module is used to reserve contiguous blocks of physical memory
|
|
for packet buffer use. It takes parameters for the number and size of blocks
|
|
to be reserved. An example is below, reserving a single 1G block:
|
|
|
|
hw.contigmem.num_buffers=1
|
|
hw.contigmem.buffer_size=1073741824
|
|
|
|
* The "nic_uio" module is used to expose the network card (NIC) hardware
|
|
directly to userspace for use with the Intel(R) DPDK. If the NIC ports to be
|
|
used are in use by an existing driver, the nic_uio module can unbind the port
|
|
from its existing driver when requested to do so. This is done by passing the
|
|
relevant PCI bus, device and function settings to the driver as parameters.
|
|
For example:
|
|
|
|
hw.nic_uio.bdfs="2:0:0,2:0:1"
|
|
|
