Split stats from debug, to make mempool statistics available without the
performance cost of continuously validating the debug cookies in the
mempool elements.
mempool_perf_autotest shows the following improvements in rate_persec.
The cost of enabling mempool debug without this patch:
-28.1 % and -74.0 %, respectively without and with cache.
The cost of enabling mempool stats (without debug) after this patch:
-5.8 % and -21.2 %, respectively without and with cache.

The module uses the pexpect python library and implements connection to
a node and two ways to interact with the node:
1. Send a string with specified prompt which will be matched after
the string has been sent to the node.
2. Send a command to be executed. No prompt is specified here.

The configuration is split into two parts, one defining the parameters
of the test run and the other defining the topology to be used.
The format of the configuration is YAML. It is validated according to a
json schema which also server as detailed documentation of the various
configuration fields. This means that the complete set of allowed values
are tied to the schema as a source of truth. This enables making changes
to parts of DTS that interface with config files without a high risk of
breaking someone's configuration.
This configuration system uses immutable objects to represent the
configuration, making IDE/LSP autocomplete work properly.
There are two ways to specify the configuration file path, an
environment variable or a command line argument, applied in that order.

With some higher GCC/CLANG version, it is not recommended to use a

Accessing this array may be considered as a risk to corrupt the

The 4.4 kernel was end of life in February 2022,
and the next LTS is 4.9 and it is reaching EOL in January 2023.
The main distro using 4.9 is Debian Stretch and it is no longer
supported. When DPDK 22.11 is released, the 4.9 kernel would
only be receiving fixes for three months; therefore
lets make the official version 4.14.
As always, current major enterprise Linux releases will continue
to be supported, but those releases don't track regular kernel
version numbering.
For full details on kernel support see:

Currently, the dpdk-telemetry.py show JSON in raw format under
interactive mode, which is not good for human reading.
E.g. The command '/ethdev/xstats,0' will output:
{"/ethdev/xstats": {"rx_good_packets": 0, "tx_good_packets": 0,
"rx_good_bytes": 0, "tx_good_bytes": 0, "rx_missed_errors": 0,
"rx_errors": 0, "tx_errors": 0, "rx_mbuf_allocation_errors": 0,
"rx_q0_packets": 0,...}}
This patch supports JSON pretty print by adding extra indent=2
parameter under interactive mode, so the same command will output:
{
"/ethdev/xstats": {
"rx_good_packets": 0,
"tx_good_packets": 0,
"rx_good_bytes": 0,
"tx_good_bytes": 0,
"rx_missed_errors": 0,
"rx_errors": 0,
"rx_mbuf_allocation_errors": 0,
"rx_q0_packets": 0,
...
}
}
Note: the non-interactive mode is made machine-readable and remains the
original way (it means don't use indent to pretty print).

In this patch,
* It is possible to switch the running mode of the distributor
using the command line argument.
* With "-c" parameter, you can run RX and Distributor
on the same core.
* Without "-c" parameter, you can run RX and Distributor
on the different core.
* Consecutive termination of the lcores fixed.
The termination order was wrong, and you couldn't terminate the
application while traffic was capturing. The current order is
RX -> Distributor -> TX -> Workers
* When "-c" parameter is active, the wasted distributor core is
also deactivated in the main function.

In the single queue model, the same descriptor queue is used by SW to
post buffer descriptors to HW and by HW to post completed descriptors
to SW.
In the split queue model, "RX buffer queues" are used to pass
descriptor buffers from SW to HW while Rx queues are used only to
pass the descriptor completions, that is, descriptors that point
to completed buffers, from HW to SW. This is contrary to the single
queue model in which Rx queues are used for both purposes.

UADK is a framework for user applications to access hardware accelerators.
UADK relies on IOMMU SVA (Shared Virtual Address) feature, which share
the same page table between IOMMU and MMU.
Thereby user application can directly use virtual address for device dma,
which enhances the performance as well as easy usability.
This patch adds the basic framework.
