Lcore-related options
~~~~~~~~~~~~~~~~~~~~~
* ``-c <core mask>``
Set the hexadecimal bitmask of the cores to run on.
* ``-l <core list>``
List of cores to run on
The argument format is ``<c1>[-c2][,c3[-c4],...]``
where ``c1``, ``c2``, etc are core indexes between 0 and 128.
* ``--lcores <core map>``
Map lcore set to physical cpu set
The argument format is::
<lcores[@cpus]>[<,lcores[@cpus]>...]
Lcore and CPU lists are grouped by ``(`` and ``)`` Within the group.
The ``-`` character is used as a range separator and ``,`` is used as a
single number separator.
The grouping ``()`` can be omitted for single element group.
The ``@`` can be omitted if cpus and lcores have the same value.
.. Note::
At a given instance only one core option ``--lcores``, ``-l`` or ``-c`` can
be used.
* ``--master-lcore <core ID>``
Core ID that is used as master.
* ``-s <service core mask>``
Hexadecimal bitmask of cores to be used as service cores.
Device-related options
~~~~~~~~~~~~~~~~~~~~~~
* ``-b, --pci-blacklist <[domain:]bus:devid.func>``
Blacklist a PCI device to prevent EAL from using it. Multiple -b options are
allowed.
.. Note::
PCI blacklist cannot be used with ``-w`` option.
* ``-w, --pci-whitelist <[domain:]bus:devid.func>``
Add a PCI device in white list.
.. Note::
PCI whitelist cannot be used with ``-b`` option.
* ``--vdev <device arguments>``
Add a virtual device using the format::
<driver><id>[,key=val, ...]
For example::
--vdev 'net_pcap0,rx_pcap=input.pcap,tx_pcap=output.pcap'
* ``-d <path to shared object or directory>``
Load external drivers. An argument can be a single shared object file, or a
directory containing multiple driver shared objects. Multiple -d options are
allowed.
* ``--no-pci``
Disable PCI bus.
Multiprocessing-related options
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* ``--proc-type <primary|secondary|auto>``
Set the type of the current process.
Memory-related options
~~~~~~~~~~~~~~~~~~~~~~
* ``-n <number of channels>``
Set the number of memory channels to use.
* ``-r <number of ranks>``
Set the number of memory ranks (auto-detected by default).
* ``-m <megabytes>``
Amount of memory to preallocate at startup.
* ``--in-memory``
Do not create any shared data structures and run entirely in memory. Implies
``--no-shconf`` and (if applicable) ``--huge-unlink``.
* ``--iova-mode <pa|va>``
Force IOVA mode to a specific value.
Debugging options
~~~~~~~~~~~~~~~~~
* ``--no-shconf``
No shared files created (implies no secondary process support).
* ``--no-huge``
Use anonymous memory instead of hugepages (implies no secondary process
support).
* ``--log-level <type:val>``
Specify log level for a specific component. For example::
--log-level eal:8
Can be specified multiple times.
Other options
~~~~~~~~~~~~~
* ``-h``, ``--help``
Display help message listing all EAL parameters.
* ``-v``
Display the version information on startup.
* ``mbuf-pool-ops-name``:
Pool ops name for mbuf to use.
