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

|
|
allowed.
|
|
