EAL parameters
|
|
==============
|
|
|
|
This document contains a list of all EAL parameters. These parameters can be
|
|
used by any DPDK application running on Linux.
|
|
|
|
Common EAL parameters
|
|
---------------------
|
|
|
|
The following EAL parameters are common to all platforms supported by DPDK.

|
|
|
|
Linux-specific EAL parameters
|
|
-----------------------------
|
|
|
|
In addition to common EAL parameters, there are also Linux-specific EAL
|
|
parameters.
|
|
|
|
Device-related options
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
* ``--create-uio-dev``
|
|
|
|
Create ``/dev/uioX`` files for devices bound to igb_uio kernel driver
|
|
(usually done by the igb_uio driver itself).
|
|
|
|
* ``--vmware-tsc-map``
|
|
|
|
Use VMware TSC map instead of native RDTSC.
|
|
|
|
* ``--no-hpet``
|
|
|
|
Do not use the HPET timer.
|
|
|
|
* ``--vfio-intr <legacy|msi|msix>``
|
|
|
|
Use specified interrupt mode for devices bound to VFIO kernel driver.
|
|
|
|
Multiprocessing-related options
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
* ``--file-prefix <prefix name>``
|
|
|
|
Use a different shared data file prefix for a DPDK process. This option
|
|
allows running multiple independent DPDK primary/secondary processes under
|
|
different prefixes.
|
|
|
|
Memory-related options
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
* ``--legacy-mem``
|
|
|
|
Use legacy DPDK memory allocation mode.
|
|
|
|
* ``--socket-mem <amounts of memory per socket>``
|
|
|
|
Preallocate specified amounts of memory per socket. The parameter is a
|
|
comma-separated list of values. For example::
|
|
|
|
--socket-mem 1024,2048
|
|
|
|
This will allocate 1 gigabyte of memory on socket 0, and 2048 megabytes of
|
|
memory on socket 1.
|
|
|
|
* ``--socket-limit <amounts of memory per socket>``
|
|
|
|
Place a per-socket upper limit on memory use (non-legacy memory mode only).
|
|
0 will disable the limit for a particular socket.
|
|
|
|
* ``--single-file-segments``
|
|
|
|
Create fewer files in hugetlbfs (non-legacy mode only).
|
|
|
|
* ``--huge-dir <path to hugetlbfs directory>``
|
|
|
|
Use specified hugetlbfs directory instead of autodetected ones.
|
|
|
|
* ``--huge-unlink``
|
|
|
|
Unlink hugepage files after creating them (implies no secondary process
|
|
support).
|
|
|
|
* ``--match-allocations``
|
|
|
|
Free hugepages back to system exactly as they were originally allocated.
|
|
|
|
Other options
|
|
~~~~~~~~~~~~~
|
|
|
|
* ``--syslog <syslog facility>``

|
|
|
|

|
|
cron
|
|
daemon
|
|
ftp
|
|
kern
|
|
