Timer Sample Application
========================
-The Timer sample application is a simple application that demonstrates the use of a timer in an Intel® DPDK application.
+The Timer sample application is a simple application that demonstrates the use of a timer in a DPDK application.
This application prints some messages from different lcores regularly, demonstrating the use of timers.
Compiling the Application
-------------------------
-#. Go to the example directory:
+To compile the sample application see :doc:`compiling`.
- .. code-block:: console
-
- export RTE_SDK=/path/to/rte_sdk cd ${RTE_SDK}/examples/timer
-
-#. 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 *Intel® DPDK Getting Started Guide* for possible *RTE_TARGET* values.
-
-#. Build the application:
-
- .. code-block:: console
-
- make
+The application is located in the ``timer`` sub-directory.
Running the Application
-----------------------
.. code-block:: console
- $ ./build/timer -c f -n 4
+ $ ./build/timer -l 0-3 -n 4
-Refer to the *Intel® DPDK Getting Started Guide* for general information on running applications and

Explanation
/*
* Call the timer handler on each core: as we don't
* need a very precise timer, so only call
- * rte_timer_manage() every ~10ms (at 2 Ghz). In a real
+ * rte_timer_manage() every ~10ms (at 2 GHz). In a real
* application, this will enhance performances as
* reading the HPET timer is not efficient.
