- Testing has been performed using Fedora 18. The setup commands and installed packages needed on other systems may be different.

+ The setup commands and installed packages needed on various systems may be different.
+ For details on Linux distributions and the versions tested, please consult the DPDK Release Notes.
-* GNU ``make``.
+* General development tools including ``make``, and a supported C compiler such as ``gcc`` (version 4.9+) or ``clang`` (version 3.4+).
-* coreutils: ``cmp``, ``sed``, ``grep``, ``arch``, etc.
+ * For RHEL/Fedora systems these can be installed using ``dnf groupinstall "Development Tools"``
-* gcc: versions 4.9 or later is recommended for all platforms.
- On some distributions, some specific compiler flags and linker flags are enabled by
- default and affect performance (``-fstack-protector``, for example). Please refer to the documentation
- of your distribution and to ``gcc -dumpspecs``.
+ * For Ubuntu/Debian systems these can be installed using ``apt install build-essential``
-* libc headers, often packaged as ``gcc-multilib`` (``glibc-devel.i686`` / ``libc6-dev-i386``;
- ``glibc-devel.x86_64`` / ``libc6-dev`` for 64-bit compilation on Intel architecture;
- ``glibc-devel.ppc64`` for 64 bit IBM Power architecture;)
+* Python, recommended version 3.5+.
-* Linux kernel headers or sources required to build kernel modules. (kernel - devel.x86_64;
- kernel - devel.ppc64)
+ * Python v3.5+ is needed to build DPDK using meson and ninja
-* Additional packages required for 32-bit compilation on 64-bit systems are:
+ * Python 2.7+ or 3.2+, to use various helper scripts included in the DPDK package.
- * glibc.i686, libgcc.i686, libstdc++.i686 and glibc-devel.i686 for Intel i686/x86_64;
+* Meson (version 0.47.1+) and ninja
- * glibc.ppc64, libgcc.ppc64, libstdc++.ppc64 and glibc-devel.ppc64 for IBM ppc_64;
+ * ``meson`` & ``ninja-build`` packages in most Linux distributions
- .. note::
+ * If the packaged version is below the minimum version, the latest versions
+ can be installed from Python's "pip" repository: ``pip3 install meson ninja``
- x86_x32 ABI is currently supported with distribution packages only on Ubuntu
- higher than 13.10 or recent Debian distribution. The only supported compiler is gcc 4.9+.
+* Library for handling NUMA (Non Uniform Memory Access).
-* libnuma-devel - library for handling NUMA (Non Uniform Memory Access).
+ * ``numactl-devel`` in RHEL/Fedora;
-* Python, version 2.7+ or 3.2+, to use various helper scripts included in the DPDK package.
+ * ``libnuma-dev`` in Debian/Ubuntu;
+
+* Linux kernel headers or sources required to build kernel modules.
+
+.. note::
+
+ Please ensure that the latest patches are applied to third party libraries
+ and software to avoid any known vulnerabilities.
**Optional Tools:**
which allows users to take leading edge advantage of IBM's latest POWER hardware features on Linux. To install
it, see the IBM official installation document.
-* libpcap headers and libraries (libpcap-devel) to compile and use the libpcap-based poll-mode driver.
- This driver is disabled by default and can be enabled by setting ``CONFIG_RTE_LIBRTE_PMD_PCAP=y`` in the build time config file.
+**Additional Libraries**
+
+A number of DPDK components, such as libraries and poll-mode drivers (PMDs) have additional dependencies.
+For DPDK builds using meson, the presence or absence of these dependencies will be
+automatically detected enabling or disabling the relevant components appropriately.
+
+For builds using make, these components are disabled in the default configuration and
+need to be enabled manually by changing the relevant setting to "y" in the build configuration file
+i.e. the ``.config`` file in the build folder.
+
+In each case, the relevant library development package (``-devel`` or ``-dev``) is needed to build the DPDK components.
-* libarchive headers and library are needed for some unit tests using tar to get their resources.
+For libraries the additional dependencies include:
+
+* libarchive: for some unit tests using tar to get their resources.
+
+* jansson: to compile and use the telemetry library.
+
+* libelf: to compile and use the bpf library.
+
+For poll-mode drivers, the additional dependencies for each driver can be
+found in that driver's documentation in the relevant DPDK guide document,
+e.g. :doc:`../nics/index`
Running DPDK Applications
**Required:**
-* Kernel version >= 3.2
+* Kernel version >= 3.16
The kernel version required is based on the oldest long term stable kernel available
at kernel.org when the DPDK version is in development.
+ Compatibility for recent distribution kernels will be kept, notably RHEL/CentOS 7.
The kernel version in use can be checked using the command::
the number of hugepages reserved at boot time is generally divided equally between the two sockets
(on the assumption that sufficient memory is present on both sockets).
-See the Documentation/kernel-parameters.txt file in your Linux source tree for further details of these and other kernel options.
+See the Documentation/admin-guide/kernel-parameters.txt file in your Linux source tree for further details of these and other kernel options.
**Alternative:**
For 1G pages, it is not possible to reserve the hugepage memory after the system has booted.
- On IBM POWER system, the nr_overcommit_hugepages should be set to the same value as nr_hugepages.
- For example, if the required page number is 128, the following commands are used::
-
- echo 128 > /sys/kernel/mm/hugepages/hugepages-16384kB/nr_hugepages
- echo 128 > /sys/kernel/mm/hugepages/hugepages-16384kB/nr_overcommit_hugepages
-
