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:

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

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,

should also simplify the building of EAL, as we can eliminate a number of

larger meson.build files (9 now vs 14 previous) - thereby making the logic
easier to follow and items easier to find.

parameters, including pulling in architecture specific parameters from an

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.

   send request to peer2, collect response from peer2, and so on.

Jianfeng Tan [Tue, 30 Jan 2018 06:58:08 +0000 (06:58 +0000)]
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.

6 years agonet/failsafe: add Rx interrupts
Moti Haimovsky [Thu, 25 Jan 2018 16:19:32 +0000 (18:19 +0200)]
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.

This is due to a typo in the name of the config option.
CONFIG_RTE_ARCH_ARM is for Makefiles. One should use RTE_ARCH_ARM.

6 years agonet/virtio-user: fix crash as features change

net/virtio-user: fix crash as features change

Since commit 59fe5e17d930 ("vhost: propagate set features handling error"),
vhost does not allow to set different features without reset.

The virtio-user driver fails to reset the device in below commit.

To fix, we send the reset message as stopping the device.

6 years agonet/mlx5: map UAR address around huge pages

net/mlx5: map UAR address around huge pages

Reserving the memory space for the UAR near huge pages helps to
**reduce** the cases where the secondary process cannot start. Those
pages being physical pages they must be mapped at the same virtual
address as in the primary process to have a
working secondary process.

As this remap is almost the latest being done by the processes
(libraries, heaps, stacks are already loaded), similar to huge pages,
there is **no guarantee** this mechanism will always work.
