654e893436 build: fix gcc warning requiring Wformat
On some CentOS/RHEL systems using gcc 8.3.1 to compile dpdk, gcc shows a
warning on every build step saying that -Wformat-nonliteral and
-Wformat-security warnings will be ignored unless -Wformat is
also specified as a compiler flag. When the build is run with -werror
the build will fail due to these warnings.

Exact warning returned:
cc1: error: -Wformat-nonliteral ignored without -Wformat
[-Werror=format-nonliteral]
cc1: error: -Wformat-security ignored without -Wformat
[-Werror=format-security]
cc1: all warnings being treated as errors

This patch adds the -Wformat flag to config/meson.build. The warning id
181 has also been suppressed in icc as icc was showing false positives
with -Wformat enabled.

c46df4c6ec config: fix kni build
When building kernel modules such as kni, the "config" directory is not
passed as a standard path in the EXTRA_CFLAGS value, meaning that the
rte_compatibility_defines.h is not found from rte_config.h. However, since
both headers are in the same directory, we can just use quotes rather than
angle-brackets to ensure the second header is always found if the first is.

b0b672aead build: add defines for compatibility with make build
The defines used to indicate what crypto, compression and eventdev drivers
were being built were different to those used in the make build, with meson
defining them with "_PMD" at the end, while make defined them with "_PMD"
in the middle and the specific driver name at the end. This might cause
compatibility issues for applications which used the older defines, which
switching to build against new DPDK releases.

As well as changing the default to match that of make, meson also
special-cases the crypto/compression/event drivers to have both defines
provided. This ensures compatibility for these macros with both meson and
make from older versions.

For a selection of other libraries and drivers, there were other
incompatibilities between the meson and make-defined macros which were not
previously highlighted in a deprecation notice, so we add per-macro
compatibility defines for these to ease the transition from make to meson.

a72cb3e765 doc: announce queue stats moving to xstats
Queue stats will be removed from basic stats to xstats.

It will be PMDs responsibility to fill queue stats based on number of
queues they have.

Until all PMDs implement the xstats, a temporary
'RTE_ETH_DEV_AUTOFILL_QUEUE_XSTATS' device flag created. PMDs switched
to the xstats should clear this flag to bypass the ethdev layer autofill
for queue stats.

e9b9739264 config: remap flags used for Arm platforms
RTE_ARCH_xx flags are used to distinguish platform architectures.
These flags can be used to pick different code paths for different
architectures at compile time.
For Arm platforms, there are 3 flags in use: RTE_ARCH_ARM,
RTE_ARCH_ARMv7 and RTE_ARCH_ARM64.
RTE_ARCH_ARM64 is for 64-bit aarch64 platforms,
and RTE_ARCH_ARM & RTE_ARCH_ARMv7 are for 32-bit platforms.
RTE_ARCH_ARMv7 is for ARMv7 platforms as its name suggested.

The issue is meaning of RTE_ARCH_ARM is not clear enough.
Because no info about platform word length is included in the name.
To make the flag names more clear, a naming scheme is proposed.

RTE_ARCH_ARM (all Arm platforms)
    |
    +----RTE_ARCH_32 (New. 32-bit platforms of all architectures)
    |        |
    |        +----RTE_ARCH_ARMv7 (ARMv7 platforms)
    |        |
    |        +----RTE_ARCH_ARMv8_AARCH32 (aarch32 state on aarch64 machine)
    |
    +----RTE_ARCH_64 (64-bit platforms of all architectures)
             |
             +----RTE_ARCH_ARM64 (64-bit Arm platforms)

RTE_ARCH_32 will be explicitly defined for 32-bit platforms.

To fit into the new naming scheme, current usage of RTE_ARCH_ARM in
project is mapped to (RTE_ARCH_ARM && RTE_ARCH_32).

Matching flags for other architectures are:
RTE_ARCH_X86
    |
    +----RTE_ARCH_32
    |        |
    |        +----RTE_ARCH_I686
    |        |
    |        +----RTE_ARCH_X86_X32
    |
    +----RTE_ARCH_64
             |
             +----RTE_ARCH_X86_64

RTE_ARCH_PPC_64 ---- RTE_ARCH_64

cce5aecf3c build: skip detecting libpcap via pcap-config
When compiling for a slightly different architecture, e.g. 32-bit on 64-bit
systems using CFLAGS rather than a cross-file, the pcap-config utility can
often return parameters that are unusable for the build in question, i.e.
providing the native 64-bit library paths rather than checking for 32-bit
equivalent.

Since many distros now include a version of libpcap with a
pkg-config file, and for those that don't find-library should work ok as a
fallback, we can explicitly just use pkg-config in the dependency search,
causing meson to skip trying to use pcap-config.

76d794566d net/hns3: maximize queue number
The maximum number of queues for hns3 PF and VF driver is 64 based on
hns3 network engine with revision_id equals 0x21. Based on hns3 network
engine with revision_id equals 0x30, the hns3 PF PMD driver can support
up to 1280 queues, and hns3 VF PMD driver can support up to 128 queues.

The following points need to be modified to support maximizing queue
number and maintain better compatibility:
1) Maximizing the number of queues for hns3 PF and VF PMD driver In
   current version, VF is not supported when PF is driven by hns3 PMD
   driver. If maximum queue numbers allocated to PF PMD driver is less
   than total tqps_num allocated to this port, all remaining number of
   queues are mapped to VF function, which is unreasonable. So we fix
   that all remaining number of queues are mapped to PF function.

   Using RTE_LIBRTE_HNS3_MAX_TQP_NUM_PER_PF which comes from
   configuration file to limit the queue number allocated to PF device
   based on hns3 network engine with revision_id greater than 0x30. And
   PF device still keep the maximum 64 queues based on hns3 network
   engine with revision_id equals 0x21.

   Remove restriction of the macro HNS3_MAX_TQP_NUM_PER_FUNC on the
   maximum number of queues in hns3 VF PMD driver and use the value
   allocated by hns3 PF kernel netdev driver.

2) According to the queue number allocated to PF device, a variable
   array for Rx and Tx queue is dynamically allocated to record the
   statistics of Rx and Tx queues during the .dev_init ops
   implementation function.
3) Add an extended field in hns3_pf_res_cmd to support the case that
   numbers of queue are greater than 1024.
4) Use new base address of Rx or Tx queue if QUEUE_ID of Rx or Tx queue
   is greater than 1024.
5) Remove queue id mask and use all bits of actual queue_id as the
   queue_id to configure hardware.
6) Currently, 0~9 bits of qset_id in hns3_nq_to_qs_link_cmd used to
   record actual qset id and 10 bit as VLD bit are configured to
   hardware. So we also need to use 11~15 bits when actual qset_id is
   greater than 1024.
7) The number of queue sets based on different network engine are
   different. We use it to calculate group number and configure to
   hardware in the backpressure configuration.
8) Adding check operations for number of Rx and Tx queue user configured
   when mapping queue to tc Rx queue numbers under a single TC must be
   less than rss_size_max supported by a single TC. Rx and Tx queue
   numbers are allocated to every TC by average. So Rx and Tx queue
   numbers must be an integer multiple of 2, or redundant queues are not
   available.
9) We can specify which packets enter the queue with a specific queue
   number, when creating flow table rules by rte_flow API. Currently,
   driver uses 0~9 bits to record the queue_id. So it is necessary to
   extend one bit field to record queue_id and configure to hardware, if
   the queue_id is greater than 1024.

e356aa46ad avoid libfdt checks adding full paths to pkg-config
The checks for libfdt try dependency() first which would only work if
a pkg-config would be present but libfdt has none.
Then it probes for the lib path itself via cc.find_library.

But later it adds the result of either probe to ext_deps which ends up
in build and also the resulting pkg-config to contain toolchain versioned
paths in Libs.private like:
  /usr/lib/gcc/x86_64-linux-gnu/9/../../../x86_64-linux-gnu/libfdt.so
which obviously breaks on toolchain updates.

In general libs used multiple times - ipn3ke + ifpga in this case - are
checked centrally in config/meson.build so move it there and fix the
adding of dependencies to not use the full file path.

The result is libfdt in pkg-config now showing up as:
  Libs.private: -pthread -lm -ldl -lnuma -lfdt -lpcap

This lib adds the support for those kind of devices.

The RegEx Device API is composed of two parts:
- The application-oriented RegEx API that includes functions to setup
  a RegEx device (configure it, setup its queue pairs and start it),
  update the rule database and so on.

- The driver-oriented RegEx API that exports a function allowing
  a RegEx poll Mode Driver (PMD) to simultaneously register itself as
  a RegEx device driver.

RegEx: A regular expression is a concise and flexible means for matching
strings of text, such as particular characters, words, or patterns of
characters. A common abbreviation for this is â~@~\RegExâ~@~].

RegEx device: A hardware or software-based implementation of RegEx
device API for PCRE based pattern matching syntax and semantics.

PCRE RegEx syntax and semantics specification:
http://regexkit.sourceforge.net/Documentation/pcre/pcrepattern.html

RegEx queue pair: Each RegEx device should have one or more queue pair to
transmit a burst of pattern matching request and receive a burst of
receive the pattern matching response. The pattern matching
request/response embedded in *rte_regex_ops* structure.

Rule: A pattern matching rule expressed in PCRE RegEx syntax along with
Match ID and Group ID to identify the rule upon the match.

Rule database: The RegEx device accepts regular expressions and converts
them into a compiled rule database that can then be used to scan data.
Compilation allows the device to analyze the given pattern(s) and
pre-determine how to scan for these patterns in an optimized fashion that
would be far too expensive to compute at run-time. A rule database
contains a set of rules that compiled in device specific binary form.

Match ID or Rule ID: A unique identifier provided at the time of rule
creation for the application to identify the rule upon match.

Group ID: Group of rules can be grouped under one group ID to enable
rule isolation and effective pattern matching. A unique group identifier
provided at the time of rule creation for the application to identify
the rule upon match.

Scan: A pattern matching request through *enqueue* API.

It may possible that a given RegEx device may not support all the
features
of PCRE. The application may probe unsupported features through
struct rte_regexdev_info::pcre_unsup_flags

By default, all the functions of the RegEx Device API exported by a PMD
are lock-free functions which assume to not be invoked in parallel on
different logical cores to work on the same target object. For instance,
the dequeue function of a PMD cannot be invoked in parallel on two logical
cores to operates on same RegEx queue pair. Of course, this function
can be invoked in parallel by different logical core on different queue
pair. It is the responsibility of the upper level application to
enforce this rule.

In all functions of the RegEx API, the RegEx device is
designated by an integer >= 0 named the device identifier *dev_id*

At the RegEx driver level, RegEx devices are represented by a generic
data structure of type *rte_regexdev*.
RegEx devices are dynamically registered during the PCI/SoC device
probing phase performed at EAL initialization time.
When a RegEx device is being probed, a *rte_regexdev* structure and
a new device identifier are allocated for that device. Then, the
regexdev_init() function supplied by the RegEx driver matching the
probed device is invoked to properly initialize the device.

The role of the device init function consists of resetting the hardware
or software RegEx driver implementations.

If the device init operation is successful, the correspondence between
the device identifier assigned to the new device and its associated
*rte_regexdev* structure is effectively registered.
Otherwise, both the *rte_regexdev* structure and the device identifier
are freed.

The functions exported by the application RegEx API to setup a device
designated by its device identifier must be invoked in the following
order:
    - rte_regexdev_configure()
    - rte_regexdev_queue_pair_setup()
    - rte_regexdev_start()

Then, the application can invoke, in any order, the functions
exported by the RegEx API to enqueue pattern matching job, dequeue
pattern matching response, get the stats, update the rule database,
get/set device attributes and so on

If the application wants to change the configuration (i.e. call
rte_regexdev_configure() or rte_regexdev_queue_pair_setup()), it must
call rte_regexdev_stop() first to stop the device and then do the
reconfiguration before calling rte_regexdev_start() again. The enqueue and
dequeue functions should not be invoked when the device is stopped.

Finally, an application can close a RegEx device by invoking the
rte_regexdev_close() function.

Each function of the application RegEx API invokes a specific function
of the PMD that controls the target device designated by its device
identifier.

For this purpose, all device-specific functions of a RegEx driver are
supplied through a set of pointers contained in a generic structure of
type *regexdev_ops*.
The address of the *regexdev_ops* structure is stored in the
*rte_regexdev* structure by the device init function of the RegEx driver,
which is invoked during the PCI/SoC device probing phase, as explained
earlier.

In other words, each function of the RegEx API simply retrieves the
*rte_regexdev* structure associated with the device identifier and
performs an indirect invocation of the corresponding driver function
supplied in the *regexdev_ops* structure of the *rte_regexdev*
structure.

For performance reasons, the address of the fast-path functions of the
RegEx driver is not contained in the *regexdev_ops* structure.
Instead, they are directly stored at the beginning of the *rte_regexdev*
structure to avoid an extra indirect memory access during their
invocation.

RTE RegEx device drivers do not use interrupts for enqueue or dequeue
operation. Instead, RegEx drivers export Poll-Mode enqueue and dequeue
functions to applications.

The *enqueue* operation submits a burst of RegEx pattern matching
request to the RegEx device and the *dequeue* operation gets a burst of
pattern matching response for the ones submitted through *enqueue*
operation.

Typical application utilisation of the RegEx device API will follow the
following programming flow.

- rte_regexdev_configure()
- rte_regexdev_queue_pair_setup()
- rte_regexdev_rule_db_update() Needs to invoke if precompiled rule
  database not
  provided in rte_regexdev_config::rule_db for rte_regexdev_configure()
  and/or application needs to update rule database.
- rte_regexdev_rule_db_compile_activate() Needs to invoke if
  rte_regexdev_rule_db_update function was used.
- Create or reuse exiting mempool for *rte_regex_ops* objects.
- rte_regexdev_start()
- rte_regexdev_enqueue_burst()
- rte_regexdev_dequeue_burst()

68b1f1cda5 build: check AVX512 rather than binutils version
Rather than checking the binutils version number, which can lead to
unnecessary disabling of AVX512 if fixes have been backported to distro
versions, we can instead check the output of "as" from binutils to see if
it is correct.

The check in the script uses the minimal assembly reproduction code posted
to the public bug tracker for gcc/binutils for those issues [1]. If the
binutils bug is present, the instruction parameters - specifically the
displacement parameter - will be different in the disassembled output
compared to the input. Therefore the check involves assembling a single
instruction and disassembling it again, checking that the two match.

and the legacy support is built when the telemetry config flag is set.

Telemetry now has EAL flags, shown below:
"--telemetry" = Enables telemetry (this is default if no flags given)
"--no-telemetry" = Disables telemetry

When telemetry is enabled, it will attempt to open the new socket
version, and also the legacy support socket (this will depend on Jansson
