93b2a8501c config: add option for atomic mbuf reference counting
RTE_MBUF_REFCNT_ATOMIC = 0 is not necessary for applications like
Seastar, where it's safe to assume that the mbuf refcnt is only
updated by a single core only.

8ef09fdc50 build: add optional NUMA and CPU counts detection
Add an option to automatically discover the host's NUMA and CPU counts
and use those values for a non cross-build.
Give users the option to override the per-arch default values or values
from cross files by specifying them on the command line with -Dmax_lcores
and -Dmax_numa_nodes.

bf66003b51 build: use platform for generic and native builds
The current meson option 'machine' should only specify the ISA, which is
not sufficient for Arm, where setting ISA implies other settings as well
(and is used in Arm configuration as such).
Use the existing 'platform' meson option to differentiate the type of
the build (native/generic) and set ISA accordingly, unless the user
chooses to override it with a new option, 'cpu_instruction_set'.
The 'machine' option set the ISA in x86 builds and set native/default
'build type' in aarch64 builds. These two new variables, 'platform' and
'cpu_instruction_set', now properly set both ISA and build type for all
architectures in a uniform manner.
The 'machine' option also doesn't describe very well what it sets. The
new option, 'cpu_instruction_set', is much more descriptive. Keep
'machine' for backwards compatibility.

Add support for the disable_libs option, to allow disabling the build of
particular libraries. As part of this, maintain a list of what libraries
can safely be disabled, without breaking the build - for now this list is
solely those libraries which are not built on FreeBSD, kni, power and
vhost. This list can be expanded by future patches.

Add Arm SoC configuration sets to Arm meson.build and add an arch

2e33309ebe config: enable/disable drivers in Arm builds
Add support for enabling or disabling drivers for Arm cross build. Do
not implement any enable/disable lists yet.

Enabling drivers is useful when building for an SoC where we only want
to build a few drivers. That way the list won't be too long.

Similarly, disabling drivers is useful when we want to disable only a
few drivers.

Both of these are advantageous mainly in aarch64 -> aarch64 (or arch ->
same arch) builds, where the build machine may have the required driver
dependencies, yet we don't want to build drivers for a specific SoC.

If enable_drivers is a non-empty list, build only those drivers,
otherwise build all drivers and add them to enable_drivers.  If
disable_drivers is non-empty list, build all drivers specified in
enable_drivers except those in disable_drivers.

There are two drivers, bus/pci and bus/vdev, which break the build if
not enabled. Address this by always enabling these if the user disables
them or doesn't specify in their allowlist.

Also remove the old Makefile arm configuration options which don't do
anything in Meson.

3b4f41a10c build: support KNI cross-compilation
The KNI linux module is using a custom target for building, which
doesn't take into account any cross compilation arguments. The arguments
in question are ARCH, CROSS_COMPILE (for gcc, clang) and CC, LD (for

target.

The user supplied path may not contain the 'build' directory, such as
when using cross-compiled headers, so only append that in the default
case (when no path is supplied in native builds) and use the unmodified
path from the user otherwise. Also modify the install path accordingly.

05050ac4ce build: add header includes check
To verify that all DPDK headers are ok for inclusion directly in a C file,
and are not missing any other pre-requisite headers, we can auto-generate
for each header an empty C file that includes that header. Compiling these
files will throw errors if any header has unmet dependencies.

For some libraries, there may be some header files which are not for direct
inclusion, but rather are to be included via other header files. To allow
later checking of these files for missing includes, we separate out the
indirect include files from the direct ones.

To ensure ongoing compliance, we enable this build test as part of the
default x86 build in "test-meson-builds.sh".

6affeabaf3 net/mlx: add static ibverbs linkage with meson
The libibverbs (and libmlx4/5) can be statically embedded
in the shared PMD library, or in the application with the static PMD.
It was supported with make build system in
commit 2c0dd7b69f ("config: add static linkage of mlx dependency").

The same feature is enabled with meson when using pkg-config
(i.e. only if the call to dependency() is successful).
The fallback method for searching library with cc.find_library()
is not supported because the dependencies of the found library
would not be linked (no such info in .a file unlike .so).

The main difference, in meson build system, is the generated .pc file
giving arguments to link DPDK with the application.
Unfortunately the .pc file will not keep memory of the static linkage
option for libibverbs.

cba806e07d build: change ABI versioning to global
As per new ABI policy [1], all of the libraries are now versioned using
one global ABI version. Stable libraries use the MAJOR.MINOR ABI
version for their shared objects, while experimental libraries
use the 0.MAJORMINOR convention for their versioning.
Experimental library versioning is managed globally. Changes in this
patch implement the necessary steps to enable that.

The CONFIG_RTE_MAJOR_ABI option was introduced to permit multiple
DPDK versions installed side by side. The problem is now addressed
through the new ABI policy, and thus can be removed.

[David] For external libraries relying on Makefile, LIBABIVER is
preserved to avoid using DPDK global ABI version.

   ninja -C output install

Note: LD_LIBRARY_PATH before ninja is necessary when the meson

such situation the LD_LIBRARY_PATH is necessary to invoke the

b5dc795a8a test: build app with meson as dpdk-test
This patch enables the test/test app to be built. It also adds
the test binary to be a meson-test, which allows the meson test
infrastructure to be used to run tests.

Tests are listed using the same test binary, however each test
sets a different DPDK_TEST environment variable. The string contents
of this DPDK_TEST env var is entered in the command line interface.
As such, the familiar test names such as "ring_perf_autotest" etc
are valid tests to run using this meson test infrastructure.

Note that the tests are run serially, given that we cannot run
multiple primary processes at a time. As each test must initialize
EAL this takes some time depending on the number of hugepages.
In future, we could improve this to run multiple tests from one
EAL init, but it is out of scope for this patchset.

Finally, an option to build the tests is added to the meson build
options. When disabled, the unit test code in test/test is not
compiled. The default is set to 'true'. To disable, run:

$ meson configure -Dtests=false

Add support for having selected example apps built as part of a meson,
ninja build. By default none are built, and those to be built should be
named directly in the -Dexamples='' meson configuration argument.

This is useful for developers working on a feature who want to use a
suitable example, or examples, to test that feature, as they can compile
everything up in one go, and run the example without having to do a ninja
install first.

This commit adds examples which don't consist of multiple apps in
subdirectories to the meson build, so they can be built by default by
passing -Dexamples parameter to meson.

Not included are the following examples:
* ethtool
* multi-process
* netmap_compat
* performance-thread
* quota_watermark
* server_node_efd
* vm_power_manager

To test the apps added here, use the following command, merged to one line,
to add them to your meson build (command to be run inside the build
directory):

meson configure -Dexamples=bbdev_app,bond,cmdline,distributor,\
	eventdev_pipeline_sw_pmd, exception_path,helloworld,\
	ip_fragmentation,ip_pipeline,ip_reassembly, ipsec-secgw,\

a25a650be5 build: add infrastructure for meson and ninja builds
To build with meson and ninja, we need some initial infrastructure in
place. The build files for meson always need to be called "meson.build",
and options get placed in meson_options.txt

This commit adds a top-level meson.build file, which sets up the global
variables for tracking drivers, libraries, etc., and then includes other
build files, before finishing by writing the global build configuration
header file and a DPDK pkgconfig file at the end, using some of those same
globals.

From the top level build file, the only include file thus far is for the
config folder, which does some other setup of global configuration
parameters, including pulling in architecture specific parameters from an
architectural subdirectory. A number of configuration build options are
provided for the project to tune a number of global variables which will be
used later e.g. max numa nodes, max cores, etc. These settings all make
their way to the global build config header "rte_build_config.h". There is
also a file "rte_config.h", which includes "rte_build_config.h", and this
file is meant to hold other build-time values which are present in our
current static build configuration but are not normally meant for
user-configuration. Ideally, over time, the values placed here should be
moved to the individual libraries or drivers which want those values.
