Performance Thread Sample Application
=====================================
Compiling the Application
-------------------------
-The application is located in the sample application folder in the
-``performance-thread`` folder.
-
-#. Go to the example applications folder
-
- .. code-block:: console
-
- export RTE_SDK=/path/to/rte_sdk
- cd ${RTE_SDK}/examples/performance-thread/l3fwd-thread
-
-#. Set the target (a default target is used if not specified). For example:
- .. code-block:: console
-
- export RTE_TARGET=x86_64-native-linuxapp-gcc
-
- See the *DPDK Linux Getting Started Guide* for possible RTE_TARGET values.
-
-#. Build the application:
-
- make
+To compile the sample application see :doc:`compiling`.
+The application is located in the `performance-thread/l3fwd-thread` sub-directory.
Running the Application
-----------------------
--tx(lcore,thread)[,(lcore,thread)]
[--enable-jumbo] [--max-pkt-len PKTLEN]] [--no-numa]
[--hash-entry-num] [--ipv6] [--no-lthreads] [--stat-lcore lcore]
+ [--parse-ptype]
Where:
* ``--stat-lcore``: optional, run CPU load stats collector on the specified
lcore.
+* ``--parse-ptype:`` optional, set to use software to analyze packet type.
+ Without this option, hardware will check the packet type.
+
The parameters of the ``--rx`` and ``--tx`` options are:
* ``--rx`` parameters
For example, the following places every l-thread on different lcores::
- l3fwd-thread -c ff -n 2 -- -P -p 3 \
+ l3fwd-thread -l 0-7 -n 2 -- -P -p 3 \
--rx="(0,0,0,0)(1,0,1,1)" \
--tx="(2,0)(3,1)"
The following places RX l-threads on lcore 0 and TX l-threads on lcore 1 and 2
and so on::
- l3fwd-thread -c ff -n 2 -- -P -p 3 \
+ l3fwd-thread -l 0-7 -n 2 -- -P -p 3 \
--rx="(0,0,0,0)(1,0,0,1)" \
--tx="(1,0)(2,1)"
For example, the following places every EAL thread on different lcores::
- l3fwd-thread -c ff -n 2 -- -P -p 3 \
+ l3fwd-thread -l 0-7 -n 2 -- -P -p 3 \
--rx="(0,0,0,0)(1,0,1,1)" \
--tx="(2,0)(3,1)" \
--no-lthreads
The following places RX EAL threads on lcore 0 and TX EAL threads on lcore 1
and 2 and so on::
- l3fwd-thread -c ff -n 2 --lcores="(0,1)@0,(2,3)@1" -- -P -p 3 \
+ l3fwd-thread -l 0-7 -n 2 --lcores="(0,1)@0,(2,3)@1" -- -P -p 3 \
--rx="(0,0,0,0)(1,0,1,1)" \
--tx="(2,0)(3,1)" \
--no-lthreads
a) Start every thread on different scheduler (1:1)::
- l3fwd-thread -c ff -n 2 -- -P -p 3 \
+ l3fwd-thread -l 0-7 -n 2 -- -P -p 3 \
--rx="(0,0,0,0)(1,0,1,1)" \
--tx="(2,0)(3,1)"
EAL thread equivalent::
- l3fwd-thread -c ff -n 2 -- -P -p 3 \
+ l3fwd-thread -l 0-7 -n 2 -- -P -p 3 \
--rx="(0,0,0,0)(1,0,1,1)" \
--tx="(2,0)(3,1)" \
--no-lthreads
Start 4 L-threads on lcore 0::
- l3fwd-thread -c ff -n 2 -- -P -p 3 \
+ l3fwd-thread -l 0-7 -n 2 -- -P -p 3 \
--rx="(0,0,0,0)(1,0,0,1)" \
--tx="(0,0)(0,1)"
Start 4 EAL threads on cpu-set 0::
- l3fwd-thread -c ff -n 2 --lcores="(0-3)@0" -- -P -p 3 \
+ l3fwd-thread -l 0-7 -n 2 --lcores="(0-3)@0" -- -P -p 3 \
--rx="(0,0,0,0)(1,0,0,1)" \
--tx="(2,0)(3,1)" \
--no-lthreads
Start 2 L-threads for RX on lcore 0, and 2 L-threads for TX on lcore 1::
- l3fwd-thread -c ff -n 2 -- -P -p 3 \
+ l3fwd-thread -l 0-7 -n 2 -- -P -p 3 \
--rx="(0,0,0,0)(1,0,0,1)" \
--tx="(1,0)(1,1)"
Start 2 EAL threads for RX on cpu-set 0, and 2 EAL threads for TX on
cpu-set 1::
- l3fwd-thread -c ff -n 2 --lcores="(0-1)@0,(2-3)@1" -- -P -p 3 \
+ l3fwd-thread -l 0-7 -n 2 --lcores="(0-1)@0,(2-3)@1" -- -P -p 3 \
--rx="(0,0,0,0)(1,0,1,1)" \
--tx="(2,0)(3,1)" \
--no-lthreads
On initialization an L-thread scheduler is started on every EAL thread. On all
but the master EAL thread only a a dummy L-thread is initially started.
The L-thread started on the master EAL thread then spawns other L-threads on
-different L-thread schedulers according the the command line parameters.
+different L-thread schedulers according the command line parameters.
The RX threads poll the network interface queues and post received packets
to a TX thread via the corresponding software ring.
