f5ab2074cf doc: rebuild with meson whenever a file changes
Add proper support for calling sphinx whenever a file in the doc
directory changes. This is accomplished by using a wrapper script
for sphinx, which runs sphinx but also emits a gcc-format dependency
file listing all the doc files. This is used by ninja so that any
change to the doc files triggers a rebuild of the docs.

 in version map
 Please add __rte_experimental to the definition of
 rte_flow_dynf_metadata_offs

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.

e09848337c build: fix ninja install on FreeBSD
The post-install script to symlink the PMDs from their own PMD directory to
the regular lib directory (so they would be found by ld at runtime) was
using the "-r" flag to ln to create relative symlinks. This flag is
unsupported by ln on FreeBSD causing the ninja install step to fail.

Reworking the script to take the relative driver path as parameter removes
the need for ln to calculate the relative path ensuring compatibility with
FreeBSD.

As part of the fix, we move the registration of the install script to the
config/meson.build file, from the top level one. This improves readability
as the script takes as parameters the variables set in that file.

49bcce1383 buildtools: prevent experimental symbol match on substring
The experimental symbol check script matched on the regexes
"\.text.*$SYM" and "\.text\.experimental.*$SYM" which allows for
substring matches.
If a symbol is leading substring of another one (e.g. symbol foo
is a substring of symbol foobar), it would match on symbols
when it shouldn't.

It is fixed by matching additionally on the end of line
so that symbols are an exact match.

ac7f4af813 pmdinfogen: fix resource leak of file object
Coverity flags an issue where the resources used by the FILE object for
the temporary input file are leaked. This is a very minor issue, but is
easily fixed, while also avoiding later problems where we try to close
an invalid file descriptor in the failure case.

The fix is to use "dup()" to get a new file descriptor number rather than
using the value directly from fileno. This allows us to close the file
opened with tmpfile() within in scope block, while allowing the duplicate
to pass to the outer block and be closed when the function terminates.

As a side-effect I/O in the function is therefore changed from using stdio
fread/fwrite to read/write system calls.

45775d7512 drivers: improve pmdinfo generation with meson
Since meson 0.44, changing any file inside a PMD directory (quite
correctly) triggers a full re-run of meson on build, rather than an
incremental build as with earlier versions. This rerun is needed because
we use "grep" in meson to search for files on which to run pmdinfogen, and
changing any of those files means that grep and, therefore meson, needs to
be rerun. [Previous versions of meson did not track this dependency on the
grep command, and so did incremental builds only.]

If, however, we take advantage of pmdinfogen's ability to use stdin and
stdout instead of files, we can instead use a shell script to process an
entire static archive and generate a single .c file from it. This
eliminates the need for grep, and means that changes to a PMD file only
need an incremental build - a significant time saving.

Instead we store the march flag as a variable, and add it to the default

compile successfully in a cross-compilation environment.

ed4d43d73e build: symlink drivers to library directory
With the introduction of bus drivers, we now have a situation where
driver libraries will start to depend upon each other. Because of this,
the driver libs need to be discoverable by the dynamic loader.

There are three options to fix this:
1. Force the user to put the $libdir/dpdk/drivers folder into their
	library path.
2. Move all libraries from drivers sub-directory to $libdir.
3. Symlink all libraries from the subfolder to the main library dir.

Option 1 is not great for usability or distro packaging, and option 2
means that we can't have EAL load all drivers from a known path
automatically (as it would error out on non-PMD libs), so option 3 was
chosen as the best fix. The only downside is that on a "ninja uninstall"
the symlinks are not removed, as they are unknown to meson/ninja.

74d6c4a72e pmdinfogen: fix cross compilation for ARM big endian
Cross compiling DPDK for BE mode on ARM results into errors
"PMDINFO portal/dpaa2_hw_dpio.o.pmd.c No drivers registered"

The original code assumes the sh_size to be 32 bit, while it can
be Elf32_Word or Elf64_Xword based on 32bit or 64 bit systems.

This patches replaces the sh_size conversion routines to use ADDR_SIZE

a462a6a9e7 buildtools: fix icc build
There are random build errors in test reports [1]. Build error
is not directly related to DPDK but observed during DPDK build.

When I get similar unexpected build errors in my system, found
out that /dev/null is invalid.

It seems ICC overwrites the /dev/null with "icc -o /dev/null" instead
of sending output to /dev/null. This is not always reproducible, so
hard to say what exactly is triggering the error.

I suspect test-report build errors can be because of the same reason,
and it is good to add a protection for this case.

Instead of sending output to /dev/null save it to the tmp folder and
remove it back when done.

0decf84217 buildtools: zero elf info variable in pmdinfogen
This commit zeros out the elf_info struct at startup of the
pmdinfogen code. If it is not zeroed, later in the code gcc
produces "may be unused" prints. Clang does not report any
issue.

This issue is only observed when compiling pmdinfogen as an
optimized build, hence this warning is not disabled in the
existing Makefile.

This commit enables a simplification in the meson build
system, removing the requirement for "-Wno-maybe-uninitialized".

feb9f680cd mk: optimize directory dependencies
Before this patch, the management of dependencies between directories
had several issues:

- the generation of .depdirs, done at configuration is slow: it can take
  more than one minute on some slow targets (usually ~10s on a standard
  PC without -j).

- for instance, it is possible to express a dependency like:
  - app/foo depends on lib/librte_foo
  - and lib/librte_foo depends on app/bar
  But this won't work because the directories are traversed with a
  depth-first algorithm, so we have to choose between doing 'app' before
  or after 'lib'.

- the script depdirs-rule.sh is too complex.

- we cannot use "make -d" for debug, because the output of make is used for
  the generation of .depdirs.

This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.

After this commit, "make config" is almost immediate.

7a514a0070 buildtools: allow symlinks within a source directory
When creating the symlinks for header files to the include folder, the
relpath script dereferenced all symlinks. This made it impossible to
have file A.h renamed to B.h and then symlinked back to its original
name. This is useful to be able to do when refactoring or reworking
a library. Change this so that we just use the dirname of the path from
readlink, we can use the basename as it was originally, even if it was a
symlink.

112fc39b82 pmdinfogen: fix endianness with cross-compilation
pmdinfogen has a bug in which, during build, it pulls in rte_byteorder.h to
obtain the rte macros for byteswapping between the cpu byte order and big or
little endian.  Unfortunately, pmdinfogen is a tool that is only meant to be run
during the build of dpdk components, and so, it runs on the host.  In cross
compile environments however, the rte_byteorder.h is configured using a target
cpu, who's endianness may differ from that of the host, leading to improper
swapping.

The fix is to use host system defined byte swapping routines rather than the
dpdk provided routines.  Note that we are using non posix compliant routines, as
the posix compliant api only addresses 16 and 32 bit swaps, and we also need 64
bit swaps.  Those macros exist (via endian.h), but BSD and Linux put that header
in different locations so some ifdeffery is required.

Tested successfully by myself on Linux and BSD systems.
