[dpdk-dev] [PATCH 0/5] Update docs for installing on FreeBSD

[Bruce Richardson]

Update the FreeBSD GSG guide to cover:

* installing from package as well as via ports collection
* building and installing manually via meson and ninja
* building examples using the pkg-config file, since both the port/pkg
  and building from source use meson.
* other general tidy-up.

[dpdk-dev] [PATCH 1/5] doc: update intro to FreeBSD GSG

[Bruce Richardson]

Update the introduction section note, to add in the fact that DPDK is now
packaged in FreeBSD, i.e. available as a pre-built binary package, as well
as being in the ports collection for manual building.

 Compiling the DPDK Target from Source
 =====================================
 
-System Requirements
--------------------
+Prerequisites
+-------------
 
-The DPDK and its applications require the GNU make system (gmake)
-to build on FreeBSD. Optionally, gcc may also be used in place of clang
-to build the DPDK, in which case it too must be installed prior to
-compiling the DPDK. The installation of these tools is covered in this
-section.
+The following FreeBSD packages are required to build DPDK:
 
-Compiling the DPDK requires the FreeBSD kernel sources, which should be
-included during the installation of FreeBSD on the development platform.
-The DPDK also requires the use of FreeBSD ports to compile and function.
+* meson
+* ninja
+* pkgconf
 
-To use the FreeBSD ports system, it is required to update and extract the FreeBSD
-ports tree by issuing the following commands:
+These can be installed using (as root)::
 
-.. code-block:: console
-
-    portsnap fetch
-    portsnap extract
-
-If the environment requires proxies for external communication, these can be set
-using:
-
-.. code-block:: console
-
-    setenv http_proxy <my_proxy_host>:<port>
-    setenv ftp_proxy <my_proxy_host>:<port>
-
-The FreeBSD ports below need to be installed prior to building the DPDK.
-In general these can be installed using the following set of commands::
-
-   cd /usr/ports/<port_location>
-
-   make config-recursive
-
-   make install
-
-   make clean
-
-Each port location can be found using::
-
-   whereis <port_name>
-
-The ports required and their locations are as follows:
-
-* dialog4ports: ``/usr/ports/ports-mgmt/dialog4ports``
-
-* GNU make(gmake): ``/usr/ports/devel/gmake``
-
-* coreutils: ``/usr/ports/sysutils/coreutils``
-
-For compiling and using the DPDK with gcc, the compiler must be installed
-from the ports collection:
-
-* gcc: version 4.9 is recommended ``/usr/ports/lang/gcc49``.
-  Ensure that ``CPU_OPTS`` is selected (default is OFF).
-
-When running the make config-recursive command, a dialog may be presented to the
-user. For the installation of the DPDK, the default options were used.
-
-.. note::
+  pkg install meson pkgconf
 
-    To avoid multiple dialogs being presented to the user during make install,
-    it is advisable before running the make install command to re-run the
-    make config-recursive command until no more dialogs are seen.
+To compile the required kernel modules for memory management and working
+with physical NIC devices, the kernel sources for FreeBSD also
+need to be installed. If not already present on the system, these can be
+installed via commands like the following, for FreeBSD 12.1 on x86_64::
 
+  fetch http://ftp.freebsd.org/pub/FreeBSD/releases/amd64/12.1-RELEASE/src.txz
+  tar -C / -xJvf src.txz
 
-Install the DPDK and Browse Sources
------------------------------------
+To enable the telemetry library in DPDK, the jansson library also needs to
+be installed, and can be installed via::
 
-First, uncompress the archive and move to the DPDK source directory:
+  pkg install jansson
 
-.. code-block:: console
-
-    unzip DPDK-<version>.zip
-    cd DPDK-<version>
-
-The DPDK is composed of several directories:
-
-*   lib: Source code of DPDK libraries
-
-*   app: Source code of DPDK applications (automatic tests)
-
-*   examples: Source code of DPDK applications
-
-*   config, buildtools, mk: Framework-related makefiles, scripts and configuration
-
-Installation of the DPDK Target Environments
---------------------------------------------
-
-The format of a DPDK target is::
-
-   ARCH-MACHINE-EXECENV-TOOLCHAIN
-
-Where:
+Individual drivers may have additional requirements. Consult the relevant
+driver guide for any driver-specific requirements of interest.
 
-* ``ARCH`` is: ``x86_64``
+Building DPDK
+-------------
 
-* ``MACHINE`` is: ``native``
+The following commands can be used to build and install DPDK on a system.
+The final, install, step generally needs to be run as root::
 
-* ``EXECENV`` is: ``freebsd``
+  meson build
+  cd build
+  ninja
+  ninja install
 
-* ``TOOLCHAIN`` is: ``gcc`` | ``clang``
-
-The configuration files for the DPDK targets can be found in the DPDK/config
-directory in the form of::
-
-    defconfig_ARCH-MACHINE-EXECENV-TOOLCHAIN
+This will install the DPDK libraries and drivers to `/usr/local/lib` with a
+pkg-config file `libdpdk.pc` installed to `/usr/local/lib/pkgconfig`. The
+DPDK test applications, such as `dpdk-testpmd` are installed to
+`/usr/local/bin`. To use these applications, it is recommended that the
+`contigmem` and `nic_uio` kernel modules be loaded first, as described in
+the next section.
 
 .. note::
 
-   Configuration files are provided with the ``RTE_MACHINE`` optimization level set.
-   Within the configuration files, the ``RTE_MACHINE`` configuration value is set
-   to native, which means that the compiled software is tuned for the platform
-   on which it is built.  For more information on this setting, and its
-   possible values, see the *DPDK Programmers Guide*.
-
-To make the target, use ``gmake install T=<target>``.
-
-For example to compile for FreeBSD use:
-
-.. code-block:: console
-
-    gmake install T=x86_64-native-freebsd-clang
-
-.. note::
-
-   If the compiler binary to be used does not correspond to that given in the
-   TOOLCHAIN part of the target, the compiler command may need to be explicitly
-   specified. For example, if compiling for gcc, where the gcc binary is called
-   gcc4.9, the command would need to be ``gmake install T=<target> CC=gcc4.9``.
-
-Browsing the Installed DPDK Environment Target
-----------------------------------------------
+        It is recommended that pkg-config be used to query information
+        about the compiler and linker flags needed to build applications
+        against DPDK.  In some cases, the path `/usr/local/lib/pkgconfig`
+        may not be in the default search paths for `.pc` files, which means
+        that queries for DPDK information may fail. This can be fixed by
+        setting the appropriate path in `PKG_CONFIG_PATH` environment
+        variable.
 
-Once a target is created, it contains all the libraries and header files for the
-DPDK environment that are required to build customer applications.
-In addition, the test and testpmd applications are built under the build/app
-directory, which may be used for testing.  A kmod directory is also present that
-contains the kernel modules to install.

[dpdk-dev] [PATCH 4/5] doc: update section on loading FreeBSD kernel modules

[Bruce Richardson]

The kernel modules are now installed in the correct system location on
install when using meson and ninja, so update the documentation to remove
any references to the "kmod" directory. Also, make a few additional updates
to improve clarity.

[dpdk-dev] [PATCH 5/5] doc: update documentation on build and running FreeBSD apps

[Bruce Richardson]

Update the documentation on building and running apps on FreeBSD, taking
account of having used meson for building. We can also update the section
on the command-line parameters, rather than claiming to be a complete list
of parameters, it should describe how to get the complete list and only
cover a few important ones.

 Compiling a Sample Application
 ------------------------------
 
-Once a DPDK target environment directory has been created (such as
-``x86_64-native-freebsd-clang``), it contains all libraries and header files required
-to build an application.
+The DPDK example applications make use of the pkg-config file installed on
+the system when DPDK is installed, and so can be built using GNU make.
 
-When compiling an application in the FreeBSD environment on the DPDK,
-the following variables must be exported:
-
-*   ``RTE_SDK`` - Points to the DPDK installation directory.
-
-*   ``RTE_TARGET`` - Points to the DPDK target environment directory.
-    For FreeBSD, this is the ``x86_64-native-freebsd-clang`` or
-    ``x86_64-native-freebsd-gcc`` directory.
-
-The following is an example of creating the ``helloworld`` application, which runs
-in the DPDK FreeBSD environment. While the example demonstrates compiling
-using gcc version 4.9, compiling with clang will be similar, except that the ``CC=``
-parameter can probably be omitted. The ``helloworld`` example may be found in the
-``${RTE_SDK}/examples`` directory.
-
-The directory contains the ``main.c`` file. This file, when combined with the
-libraries in the DPDK target environment, calls the various functions to
-initialize the DPDK environment, then launches an entry point (dispatch
-application) for each core to be utilized. By default, the binary is generated
-in the build directory.

+   BSD make cannot be used to compile the DPDK example applications. GNU
+   make can be installed using `pkg install gmake` if not already installed
+   on the FreeBSD system.
 
-.. note::
+The following shows how to compile the helloworld example app, following
+the installation of DPDK using `ninja install` as described previously::
 
-    In the above example, ``helloworld`` was in the directory structure of the
-    DPDK. However, it could have been located outside the directory
-    structure to keep the DPDK structure intact.  In the following case,
-    the ``helloworld`` application is copied to a new directory as a new starting
-    point.
