5b3a6ca6fd build: alias default build as generic
The current machine='default' build name is not descriptive. The actual
default build is machine='native'. Add an alternative string which does
the same build and better describes what we're building:
machine='generic'. Leave machine='default' for backwards compatibility.

56ea803e87 build: remove Windows export symbol list
Rather than have two files that keeps getting out of sync, let's
annotate the version.map to generate the Windows export file.

Some mlx5 symbols (haswell_broadwell_cpu, mlx5_glue, mlx5_os_*) were
only exported for Windows.
All of them are available and used by Linux too, so this patch adds
them in version.map.

Note: Existing version.map annotation achieved with:
$ for dir in lib/librte_eal drivers/common/mlx5; do
    ./buildtools/map-list-symbol.sh $dir/*.map |
    while read file version sym; do
      ! git grep -qw $sym $dir/*.def || continue;
      sed -i -e "s/$sym;/$sym; # WINDOWS_NO_EXPORT/" $dir/*.map;
    done;
  done

8d935fff55 bus/vdev: add driver IOVA VA mode requirement
This patch adds driver flag in vdev bus driver so that
vdev drivers can require VA IOVA mode to be used, which
for example the case of Virtio-user PMD.

The patch implements the .get_iommu_class() callback, that
is called before devices probing to determine the IOVA mode
to be used, and adds a check right before the device is
probed to ensure compatible IOVA mode has been selected.

It also adds a ABI exception rule to accommodate with an
update on the driver registration API

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".

6a426d733e devtools: reduce ABI checks and static binaries
When testing compilation and checking ABI compatibility,
there is no real need of static binaries eating disks.

The static linkage of applications was already well tested,
though the static examples tested with meson were limited to "l3fwd" only.
The static build test with make is limited to "helloworld" example.

The ABI compatibility is checked on shared libraries,
and there is no need to test again on similar builds.
A new parameter is added to the function "build",
so the ABI check is enabled only for native gcc and clang shared builds,
32-bit, generic armv8 and ppc cross compilations.
In other words, it is disabled for some static builds and some Arm ones.

e222b17f68 devtools: allow custom set of examples in build test
To test the installation process of DPDK using "ninja install"
test-meson-builds.sh builds a subset of the examples using "make". To allow
more flexibility for people testing, allow the set of examples chosen for
this make test to be overridden using variable "DPDK_BUILD_TEST_EXAMPLES"
in the environment.

Since a number of example apps link against drivers directly even for
shared builds, we need to ensure that LD_LIBRARY_PATH points to the main
DPDK lib folder so any dependencies of those drivers can be found e.g. that
the PCI/vdev bus driver .so is found. [All drivers are symlinked from
drivers dir back to lib dir on install, so only one dir rather than two is
needed in the path.]

a655cbd5be devtools: fix build test config inheritance from env
The variables DPDK_MESON_OPTIONS, PATH, PKG_CONFIG_PATH,
CPPFLAGS, CFLAGS and LDFLAGS can be customized in the config file
loaded by devtools/load-devel-config at each build.
The configuration can be adjusted per target thanks to the value set
in the DPDK_TARGET variable.

PKG_CONFIG_PATH is specific to each target, so it must be empty
before configuring each build from the file according to DPDK_TARGET.
Inheriting a default PKG_CONFIG_PATH for all targets does not make sense
and is prone to confusion.

DPDK_MESON_OPTIONS might take a global initial value from environment
to customize a build test from the shell. Example:
	DPDK_MESON_OPTIONS="b_lto=true"
Some target-specific options can be added in the configuration file:
	DPDK_MESON_OPTIONS="$DPDK_MESON_OPTIONS kernel_dir=$MYKERNEL"

9b83106d87 devtools: test 32-bit build

to prevent this, we can add a 32-bit build (if supported) to the

PKG_CONFIG_LIBDIR, so for now we use two common possibilities for where that
should point to in order to get a successful build.

f1602b4a86 devtools: prevent use of legacy atomic API
In order to deprecate the rte_atomic and rte_smp barrier APIs [1], prevent
the patches from using these APIs and __sync builtins in new code.
Please use __atomic builtins instead of __sync builtins, rte_atomicNN_xxx
and rte_smp_[r/w]mb APIs.

On x86 the __atomic_thread_fence(__ATOMIC_SEQ_CST) is quite expensive for
SMP case. Flag the new code which use __atomic_thread_fence API.
Please use rte_thread_fence API instead of __atomic_thread_fence builtins.

1: Refer to the locks-and-atomic-operations section in
https://doc.dpdk.org/guides/prog_guide/writing_efficient_code.html

cfe4ca1021 devtools: give some hints for ABI errors
abidiff can provide some more information about the ABI difference it
detected.
In all cases, a discussion on the mailing must happen but we can give
some hints to know if this is a problem with the script calling abidiff,
a potential ABI breakage or an unambiguous ABI breakage.

e0a439466b eal/linux: use C11 atomics for interrupt status
The event status is defined as a volatile variable and shared between
threads. Use C11 atomic built-ins with explicit ordering instead of
rte_atomic ops which enforce unnecessary barriers on aarch64.

The event status has been cleaned up by the compare-and-swap operation
when we free the event data, so there is no need to set it to invalid
after that.

7762e0139b build: remove special versioning for non stable libraries
Having a special versioning for experimental/internal libraries put a
additional maintenance cost while this status is already announced in
MAINTAINERS and the library headers/documentation.
Following discussions and vote at 05/20 TB meeting [1], use a single
versioning for all libraries in DPDK.

Note: for the ABI check, an exception [2] had been added when tweaking
this special versioning [3].
Prefer explicit libabigail rules (which will be dropped in 20.11).
