3495a68f2a examples: stop processing meson file if build impossible
Once it has been determined that an example cannot be built, there is
little point in continuing to process the meson.build file for that
example, so we can use subdir_done() to return to the calling file.
This can potentially prevent problems where later statement in the file
may cause an error on systems where the app cannot be built, e.g. on
Windows or FreeBSD.

ce6b8c3154 examples: fix port mask parsing failure handling
Giving invalid or zero portmask as command line option to
these applications will have an unexpected response.
The reason behind this is that the return value of function
that parses portmask is stored in a variable whose datatype is
unsigned int, hence returning -1 in case of zero or
invalid portmask causes an unexpected behaviour.
If we return 0 instead of -1 this issue can be resolved.
The program already contains the functionality to print
"invalid portmask" and program usage if zero is returned.

8549295db0 build/pkg-config: improve static linking flags
Rather than setting -Bstatic in the linker flags when doing a static link,
and then having to explicitly set -Bdynamic again afterwards, we can update
the pkg-config file to use -l:libfoo.a syntax to explicitly refer to the
static library in question. Since this syntax is not supported by meson's
pkg-config module directly, we can post-process the .pc files instead to
adjust them.

Once done, we can simplify the examples' makefiles and the docs by removing
the explicit static flag.

69b1bb49ed examples: hide error for missing pkg-config path flag
Some versions of pkg-config don't support the --path flag, which is not a
fatal error when building the apps. Without the flag, the makefile just
cannot track the .pc file of DPDK as a dependency of the build. Therefore,
we can ignore the error and suppress it by redirecting to /dev/null the
stderr from that call to pkg-config.

12a652a02b examples: fix build with old pkg-config
Not all versions of pkg-config in distros have support for the
--define-prefix flag [1], causing errors when building examples manually or
with test-meson-builds.sh script [2].

For the former case, we need to remove the hard-coded use of the flag in
the Makefiles.

For the latter case, the flag is necessary for builds to succeed, so we
skip the tests when it's not present, passing it as part of the pkg-config
command if it is supported.

- the "--ignore-fail-on-non-empty" flag is not present on BSD
- the call to remove the build folder would fail if there was no build

These are fixed by only removing the build folder if it exists, and by
using -p flag to rmdir in place of --ignore-fail-on-non-empty

The distributor application is bottlenecked by the distributor core,
so if we can give more frequency to this core, then the overall

This patch uses the rte_power_get_capabilities() API to query the

found (e.g. Turbo Boost is enabled), we will pin the distributor
workload to that core.

e9c6594264 examples: detect default build directory
Most examples have in their makefiles a default RTE_TARGET directory to be
used in case RTE_TARGET is not set. Rather than just using a hard-coded
default, we can instead detect what the build directory is relative to
RTE_SDK directory.

This fixes a potential issue for anyone who continues to build using
"make install T=x86_64-native-linuxapp-gcc" and skips setting RTE_TARGET
explicitly, instead relying on the fact that they were building in a
directory which corresponded to the example default path - which was
changed to "x86_64-native-linux-gcc" by commit 218c4e68c1 ("mk: use

Rather than using linuxapp and bsdapp everywhere, we can change things to

Rather than renaming the configs we can just duplicate the existing ones
with the new names using symlinks, and use the new names exclusively
internally. ["make showconfigs" also only shows the new names to keep the
list short] The result is that backward compatibility is kept fully but any
new builds or development can be done using the newer names, i.e.  both

	commit cba7f53b71 ("ethdev: introduce Tx queue offloads API")

The new API is documented in the programmer's guide:
	http://doc.dpdk.org/guides/prog_guide/poll_mode_drv.html#hardware-offload

For reminder, the main concepts in the new API were:
	- All offloads are disabled by default
	- Distinction between per port and per queue offloads.

The transition bits are now removed:
	- Translation of the old API in ethdev
	- rte_eth_conf.rxmode.ignore_offload_bitfield
	- ETH_TXQ_FLAGS_IGNORE

The old API bits are now removed:
	- Rx per-port rte_eth_conf.rxmode.[bit-fields]
	- Tx per-queue rte_eth_txconf.txq_flags
	- ETH_TXQ_FLAGS_NO*

fa47405cc1 ethdev: remove experimental flag of ports enumeration
The basic operations for ports enumeration should not be
considered as experimental in DPDK 18.05.

The iterator RTE_ETH_FOREACH_DEV was introduced in DPDK 17.05.
It uses the function the rte_eth_find_next_owned_by() to get
only ownerless ports. Its API can be considered stable.
So the flag experimental is removed from rte_eth_find_next_owned_by().

The flag experimental is removed from rte_eth_dev_count_avail()
which is the new name of the old function rte_eth_dev_count().

The flag experimental is set to rte_eth_dev_count_total()
in the .c file for consistency with the declaration in the .h file.

A lot of internal applications are fixed to not allow experimental API.

    - no hotplug, i.e. ports are never detached

Such application iterates over ports by its own mean.
The most common pattern is to request the port count and
assume ports with index in the range [0..count[ can be used.

1842d194c9 examples: enable linking both static and shared
Since the DPDK build now includes both static and shared libraries, we need
a new way to enable building the examples using either method from the one
installation. To do this, we add in a default "shared" target, and a
separate "static" target which links in the DPDK static libraries. In both
cases, the final application name is symlinked to the last-built static or
shared target, with both binaries able to co-exist in the build directory.

22119c4591 examples: use pkg-config in makefiles
Change the example app Makefiles to query if DPDK is installed and
registered using pkg-config. If so, build directly using pkg-config info,
otherwise fall back to using the original build system with RTE_SDK and
RTE_TARGET

This commit changes the makefiles for the basic examples, i.e. those which
do not have multiple subdirectories underneath the main examples dir.
Examples not covered are:

* ethtool
* multi_process
* performance-thread
* quota_watermark
* netmap_compat
* server_node_efd
* vm_power_manager

0eba4ade65 examples: put app name and sources at top of makefiles
Reorder the text in the makefiles, so that the app name and the source
files are listed first. This then will allow them to be shared later in a
combined makefile building with pkg-config and RTE_SDK-based build system.

89f0711f9d examples: build some samples with meson
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,\
	ipv4_multicast,kni,l2fwd-cat,l2fwd-crypto,l2fwd-jobstats,\
	l2fwd-keepalive,l2fwd,l3fwd-acl,l3fwd-power,l3fwd-vf,l3fwd,\
	link_status_interrupt,load_balancer,packet_ordering,ptpclient,\
	qos_meter,qos_sched,rxtx_callbacks,skeleton,tep_termination,\
	timer,vhost,vhost_scsi,vmdq,vmdq_dcb

Add an extra parameter to the ring dequeue burst/bulk functions so that
those functions can optionally return the amount of remaining objs in the
ring. This information can be used by applications in a number of ways,
for instance, with single-consumer queues, it provides a max

for instance, with single-producer queues, it provides a max

implement watermark functionality in apps, replacing the older
functionality with a more flexible version, which enables apps to
implement multiple watermark thresholds, rather than just one.
