Move the "source_org" page to after overview, where it fits better to explain the source-code layout of DPDK, before getting into details of specific libraries such as EAL. Also removes the older titles from the 3 documents which still had them. Signed-off-by: Harry van Haaren <harry.van.haaren@intel.com>

Source Organization
|
|
===================
|
|
|
|
This section describes the organization of sources in the DPDK framework.
|
|
|
|
Libraries
|
|
---------
|
|
|
|
Libraries are located in subdirectories of ``dpdk/lib``.
|
|
By convention a library refers to any code that provides an API to an application.
|
|
Typically, it generates an archive file (``.a``), but a kernel module would also go in the same directory.
|
|
|
|
Drivers
|
|
-------
|
|
|
|
Drivers are special libraries which provide poll-mode driver implementations for
|
|
devices: either hardware devices or pseudo/virtual devices. They are contained
|
|
in the *drivers* subdirectory, classified by type, and each compiles to a
|
|
library with the format ``librte_X_Y.a`` where ``X`` is the device class
|
|
name and ``Y`` is the driver name.
|
|
|
|
.. note::
|
|
|
|
Several of the ``driver/net`` directories contain a ``base``
|
|
sub-directory. The ``base`` directory generally contains code the shouldn't
|
|
be modified directly by the user. Any enhancements should be done via the
|
|
``X_osdep.c`` and/or ``X_osdep.h`` files in that directory. Refer to the
|
|
local README in the base directories for driver specific instructions.
|
|
|
|
|
|
Applications
|
|
------------
|
|
|
|
Applications are source files that contain a ``main()`` function.
|
|
They are located in the ``dpdk/app`` and ``dpdk/examples`` directories.
|
|
|
|
The app directory contains sample applications that are used to test DPDK (such as autotests)
|
|
or the Poll Mode Drivers (test-pmd).
|
|
|
|
The examples directory contains :doc:`Sample applications<../sample_app_ug/index>` that show how libraries can be used.
