f6242d0655 net/mlx: make rdma-core glue path configurable
Since rdma-core glue libraries are intrinsically tied to their respective
PMDs and used as internal plug-ins, their presence in the default search
path among other system libraries for the dynamic linker is not necessarily
desired.

This commit enables their installation and subsequent look-up at run time
in RTE_EAL_PMD_PATH if configured to a nonempty string. This path can also
be overridden by environment variables MLX[45]_GLUE_PATH.

59b91bec12 net/mlx5: spawn rdma-core dependency plug-in
When mlx5 is not compiled directly as an independent shared object (e.g.
CONFIG_RTE_BUILD_SHARED_LIB not enabled for performance reasons), DPDK
applications inherit its dependencies on libibverbs and libmlx5 through
rte.app.mk.

This is an issue both when DPDK is delivered as a binary package (Linux
distributions) and for end users because rdma-core then propagates as a
mandatory dependency for everything.

Application writers relying on binary DPDK packages are not necessarily
aware of this fact and may end up delivering packages with broken
dependencies.

This patch therefore introduces an intermediate internal plug-in
hard-linked with rdma-core (to preserve symbol versioning) loaded by the
PMD through dlopen(), so that a missing rdma-core does not cause unresolved
symbols, allowing applications to start normally.

8b9bd0efe0 app/testpmd: disable Rx VLAN offloads by default
Removed the hardcoded preconfigured Rx VLAN offload configuration
from testpmd and changed the Rx offload command line parameters from
disable to enable.

It has been decided by the Technical Board that testers who wish to
use these offloads will now have to explicitly write them in the
command-line when running testpmd.
The agreement is to keep two exceptions enabled by default in 18.02:
Rx CRC strip and Tx fast free.

Motivation:
Some PMDs such at the mlx4 may not implement all the offloads.
After the offload API rework assuming no offload is enabled by default,
  commit ce17eddefc20 ("ethdev: introduce Rx queue offloads API")
  commit cba7f53b717d ("ethdev: introduce Tx queue offloads API") trying
to enable a not supported offload is clearly an error which will cause
configuration failing.

Considering that testpmd is an application to test the PMD, it should
not fail on a configuration which was not explicitly requested.
The behavior of this test application is then turned to an opt-in
model.

5b7ba31148 ethdev: add port ownership
The ownership of a port is implicit in DPDK.
Making it explicit is better from the next reasons:
1. It will define well who is in charge of the port usage synchronization.
2. A library could work on top of a port.
3. A port can work on top of another port.

Also in the fail-safe case, an issue has been met in testpmd.
We need to check that the application is not trying to use a port which
is already managed by fail-safe.

A port owner is built from owner id(number) and owner name(string) while
the owner id must be unique to distinguish between two identical entity
instances and the owner name can be any name.
The name helps to logically recognize the owner by different DPDK
entities and allows easy debug.
Each DPDK entity can allocate an owner unique identifier and can use it
and its preferred name to owns valid ethdev ports.
Each DPDK entity can get any port owner status to decide if it can
manage the port or not.

The mechanism is synchronized for both the primary process threads and
the secondary processes threads to allow secondary process entity to be
a port owner.

Add a synchronized ownership mechanism to DPDK Ethernet devices to
avoid multiple management of a device by different DPDK entities.

The current ethdev internal port management is not affected by this
feature.

b114af1603 build: remove architecture flag as default C flag
Any flags added to the project args are automatically added to all builds,
both native and cross-compiled. This is not what we want for the -march
flag as a valid -march for the cross-compile is not valid for pmdinfogen
which is a native-build tool.

Instead we store the march flag as a variable, and add it to the default
cflags for all libs, drivers, examples, etc. This will allow pmdinfogen to
compile successfully in a cross-compilation environment.

610beca42e build: remove library special cases
The EAL and compat libraries were special-cases in the library build
process, the former because of it's complexity, and the latter because
it only consists of a single header file.

By reworking the EAL meson.build files, we can eliminate the need for it to
be a special case, by having it build up and return the list of sources,
headers, and objects and return those to the higher level build file. This
should also simplify the building of EAL, as we can eliminate a number of
meson.build files that would no longer be needed, and have fewer, but
larger meson.build files (9 now vs 14 previous) - thereby making the logic
easier to follow and items easier to find.

Once done, we can pull eal into the main library loop, with some
modifications to support it. Compat can also be pulled it once we add in a
check to handle the case of an empty sources list.

783b6e5497 eal: add synchronous multi-process communication
We need the synchronous way for multi-process communication,
i.e., blockingly waiting for reply message when we send a request
to the peer process.

We add two APIs rte_eal_mp_request() and rte_eal_mp_reply() for
such use case. By invoking rte_eal_mp_request(), a request message
is sent out, and then it waits there for a reply message. The caller
can specify the timeout. And the response messages will be collected
and returned so that the caller can decide how to translate them.

The API rte_eal_mp_reply() is always called by an mp action handler.
Here we add another parameter for rte_eal_mp_t so that the action
handler knows which peer address to reply.

 * A secondary process is only allowed to talk to the primary process.
 * If there are multiple secondary processes for the primary process,
   it will send request to peer1, collect response from peer1; then
   send request to peer2, collect response from peer2, and so on.
 * When thread-n is sending request, thread-m of that process can send
   request at the same time.
 * For pair <action_name, peer>, we guarantee that only one such request
   is on the fly.

bacaa27540 eal: add channel for multi-process communication
Previouly, there are three channels for multi-process
(i.e., primary/secondary) communication.
  1. Config-file based channel, in which, the primary process writes
     info into a pre-defined config file, and the secondary process
     reads the info out.
  2. vfio submodule has its own channel based on unix socket for the
     secondary process to get container fd and group fd from the
     primary process.
  3. pdump submodule also has its own channel based on unix socket for
     packet dump.

It'd be good to have a generic communication channel for multi-process
communication to accommodate the requirements including:
  a. Secondary wants to send info to primary, for example, secondary
     would like to send request (about some specific vdev to primary).
  b. Sending info at any time, instead of just initialization time.
  c. Share FDs with the other side, for vdev like vhost, related FDs
     (memory region, kick) should be shared.
  d. A send message request needs the other side to response immediately.

This patch proposes to create a communication channel, based on datagram
unix socket, for above requirements. Each process will block on a unix
socket waiting for messages from the peers.

Three new APIs are added:

  1. rte_eal_mp_action_register() is used to register an action,
     indexed by a string, when a component at receiver side would like
     to response the messages from the peer processe.
  2. rte_eal_mp_action_unregister() is used to unregister the action
     if the calling component does not want to response the messages.
  3. rte_eal_mp_sendmsg() is used to send a message, and returns
     immediately. If there are n secondary processes, the primary
     process will send n messages.

709676bc9c net/failsafe: add Rx interrupts
This patch is the last patch in the series of patches aimed
to add support for registering and waiting for Rx interrupts
in failsafe PMD. This allows applications to wait for Rx events
from the PMD using the DPDK rte_epoll subsystem.
The failsafe PMD presents to the application a facade of a single
device to be handled by the application while internally it manages
several devices on behalf of the application including packets
transmission and reception.
The Proposed failsafe Rx interrupt scheme follows this approach.
The failsafe PMD will present the application with a single set of
Rx interrupt vectors representing the failsafe Rx queues, while
internally it will serve as an interrupt proxy for its subdevices.
will allow applications to wait for Rx traffic from the failsafe
PMD by registering and waiting for Rx events from its Rx queues.
In order to support this the following is suggested:
  * Every Rx queue in the failsafe (virtual) device will be assigned
  * a Linux event file descriptor (efd) and an enable_interrupts flag.
  * The failsafe PMD will fill in its rte_intr_handle structure with
    the Rx efds assigned previously and register them with the EAL.
  * The failsafe driver will create a private epoll fd (epfd) and
  * will allocate enough space to handle all the Rx events from all its
    subdevices.
  * Acting as an application,
    for each Rx queue in each active subdevice the failsafe will:
      o Register the Rx queue with the EAL.
      o Pass the EAL the failsafe private epoll fd as the epfd to
        register the Rx queue event on.
      o Pass the EAL, as a parameter, the pointer to the failsafe Rx
        queue that handles this Rx queue.
      o Using the DPDK service callbacks, the failsafe PMD will launch
        an Rx proxy service that will Wait on the epoll fd for Rx
        events from the sub-devices.
      o For each Rx event received the proxy service will
          - Retrieve the pointer to failsafe Rx queue that handles
            this subdevice Rx queue from the user info returned by the
            EAL.
          - Trigger a failsafe Rx event on that queue by writing to
            the event fd unless interrupts are disabled for that queue.
  * The failsafe pmd will also implement the rx_queue_intr_enable
  * and rx_queue_intr_disable routines that will enable and disable Rx
    interrupts respectively on both on the failsafe and its subdevices.

aec9c13c52 eal: add function to release internal resources
This commit adds a new function rte_eal_cleanup().
The function serves as a hook to allow DPDK to release
internal resources (e.g.: hugepage allocations).

This function allows DPDK to become more like an ordinary
library, where the library context itself can be initialized
and cleaned up by the application.

The rte_exit() and rte_panic() functions must be considered,
particularly if they should call rte_eal_cleanup() to release any
resources or not. This patch adds the cleanup to rte_exit(),
but does not clean up on rte_panic(). The reason to not clean
up on panicing is that the developer may wish to inspect the
exact internal state of EAL and hugepages.

462d918937 keepalive: fix state alignment
The __rte_cache_aligned was applied to the whole array,
not the array elements. This leads to a false sharing between
the monitored cores.

56252de779 net/vdev_netvsc: add automatic probing
Using DPDK in Hyper-V VM systems requires vdev_netvsc driver to pair
the NetVSC netdev device with the same MAC address PCI device by
fail-safe PMD.

Add vdev_netvsc custom scan in vdev bus to allow automatic probing in
Hyper-V VM systems unless it was already specified by command line.

Add "ignore" parameter to disable this auto-detection.
