c3d31352bf net/ena: remove redundant MTU verification
Remove MTU verification from ena_mtu_set() and ena_start(). It is done
by rte_ethdev already, so there is no reason to repeat it inside the ENA

f22e705ebf eal/riscv: support RISC-V architecture
Add all necessary elements for DPDK to compile and run EAL on SiFive
Freedom U740 SoC which is based on SiFive U74-MC (ISA: rv64imafdc)
core complex.

This includes:

- EAL library implementation for rv64imafdc ISA.
- meson build structure for 'riscv' architecture. RTE_ARCH_RISCV define
  is added for architecture identification.
- xmm_t structure operation stubs as there is no vector support in the
  U74 core.

Compilation was tested on Ubuntu and Arch Linux using riscv64 toolchain.
Clang compilation currently not supported due to issues with missing
relocation relaxation.

Two rte_rdtsc() schemes are provided: stable low-resolution using rdtime
(default) and unstable high-resolution using rdcycle. User can override
the scheme by defining RTE_RISCV_RDTSC_USE_HPM=1 during compile time of
both DPDK and the application. The reasoning for this is as follows.
The RISC-V ISA mandates that clock read by rdtime has to be of constant
period and synchronized between all hardware threads within 1 tick
(chapter 10.1 in version 20191213 of RISC-V spec).
However this clock may not be of high-enough frequency for dataplane
uses. I.e. on HiFive Unmatched (FU740) it is 1MHz.
There is a high-resolution alternative in form of rdcycle which is
clocked at the core clock frequency. The drawbacks are that it may be
disabled during sleep (WFI), its frequency might change due to DVFS and
it is core-local and therefore cannot be used as a wall-clock. It can
however be used for micro-benchmarking user applications, similarly to
Aarch64's PMCCNTR PMU counter.

The platform is currently marked as linux-only because rte_cycles
implementation uses the timebase-frequency device-tree node read through
the proc file system. Such approach was chosen because Linux kernel
depends on the presence of this device-tree node.

The i40e PMD driver is disabled on RISC-V as the rv64gc ISA has no vector
operations.

The compilation of following modules has been disabled by this commit
and will be re-enabled in later commits as fixes are introduced:
net/ixgbe, net/memif, net/tap, example/l3fwd.

f93a605f2d build: add definitions for use as Meson subproject
To allow other projects to easily use DPDK as a subproject, add in the
necessary dependency definitions. Slightly different definitions are
necessary for static and shared builds, since for shared builds the
drivers should not be linked in, and the internal meson dependency
objects are more complete.

To use DPDK as a subproject fallback i.e. use installed DPDK if present,
otherwise the shipped one, the following meson statement can be used:

libdpdk = dependency('libdpdk', fallback: ['dpdk', 'dpdk_dep'])

36c3c4df13 bus/fslmc: fix VFIO setup
At device probe, the fslmc bus driver calls rte_vfio_get_group_fd() to
get a fd associated to a vfio group. This function first checks if the
group is already opened, else it opens /dev/vfio/%u, and increases the
number of active groups in default_vfio_cfg (which references the
default vfio container).

When adding the first group to a vfio_cfg, the caller is supposed to
pick an IOMMU type and set up DMA mappings for container, as it's done
by pci bus, but it is not done here. Instead, a new container is created
and used.

This prevents the pci bus driver, which uses the default_vfio_cfg
container, to configure the container because
default_vfio_cfg->active_group > 1.

This patch fixes the issue by always creating a new container (and its
associated vfio_cfg) and binding the group to it.

673c897f4d raw/ifpga: support OFS card probing
PAC N6000 is the first OFS platform, its device id is added to ifpga
device support list.

Previous FPGA platform like Intel PAC N3000 and N5000, FME DFL (Device
Feature List) starts from BAR0 by default, port DFL location is indicated
in PORTn_OFFSET register in FME. In OFS implementation, FME DFL and port
DFL location can be defined individually in PCIe VSEC (Vendor Specific
Extended Capabilities). In this patch, DFL definition is searched in VSEC,
the legacy DFL is used only when DFL VSEC is not present.

In original DFL enumeration process, AFU is expected to locate in port DFL,
but this is not the case in OFS implementation. In this patch, enumeration
can search AFU in any PF/VF which has no FME and port.

  ifpga_rawdev_cleanup()

The interrupts are unregistered in ifpga_rawdev_destroy instead of
ifpga_rawdev_close function, so rte_pmd_ifpga_cleanup cannot free

ca04c78b62 eal: get/set thread priority per thread identifier
Add functions for setting and getting the priority of a thread.
Priorities on multiple platforms are similarly determined by a priority
value and a priority class/policy.

Currently in DPDK most threads operate at the OS-default priority level
but there are cases when increasing the priority is useful. For
example, high performance applications may require elevated priority
levels.

For these reasons, EAL will expose two priority levels which are named
suggestively "normal" and "realtime_critical" and are computed as
follows:

  On Linux, the following mapping is created:
    RTE_THREAD_PRIORITY_NORMAL corresponds to
      * policy SCHED_OTHER
      * priority value:   (sched_get_priority_min(SCHED_OTHER) +
			   sched_get_priority_max(SCHED_OTHER))/2;
    RTE_THREAD_PRIORITY_REALTIME_CRITICAL corresponds to
      * policy SCHED_RR
      * priority value: sched_get_priority_max(SCHED_RR);

  On Windows, the following mapping is created:
    RTE_THREAD_PRIORITY_NORMAL corresponds to
      * class NORMAL_PRIORITY_CLASS
      * priority THREAD_PRIORITY_NORMAL
    RTE_THREAD_PRIORITY_REALTIME_CRITICAL corresponds to
      * class REALTIME_PRIORITY_CLASS (when running with privileges)
      * class HIGH_PRIORITY_CLASS (when running without privileges)
      * priority THREAD_PRIORITY_TIME_CRITICAL

Note that on Linux the resulting priority value will be 0, in
accordance to the documentation that mention the value should be 0 for
SCHED_OTHER policy.

0bee070907 eal: add seqlock
A sequence lock (seqlock) is a synchronization primitive which allows
for data-race free, low-overhead, high-frequency reads, suitable for
data structures shared across many cores and which are updated
relatively infrequently.

A seqlock permits multiple parallel readers. A spinlock is used to
serialize writers. In cases where there is only a single writer, or
writer-writer synchronization is done by some external means, the
"raw" sequence counter type (and accompanying rte_seqcount_*()
functions) may be used instead.

To avoid resource reclamation and other issues, the data protected by
a seqlock is best off being self-contained (i.e., no pointers [except
to constant data]).

One way to think about seqlocks is that they provide means to perform
atomic operations on data objects larger than what the native atomic
machine instructions allow for.

DPDK seqlocks (and the underlying sequence counters) are not
preemption safe on the writer side. A thread preemption affects
performance, not correctness.

A seqlock contains a sequence number, which can be thought of as the
generation of the data it protects.

A reader will
  1. Load the sequence number (sn).
  2. Load, in arbitrary order, the seqlock-protected data.
  3. Load the sn again.
  4. Check if the first and second sn are equal, and even numbered.
     If they are not, discard the loaded data, and restart from 1.

The first three steps need to be ordered using suitable memory fences.

A writer will
  1. Take the spinlock, to serialize writer access.
  2. Load the sn.
  3. Store the original sn + 1 as the new sn.
  4. Perform load and stores to the seqlock-protected data.
  5. Store the original sn + 2 as the new sn.
  6. Release the spinlock.

Proper memory fencing is required to make sure the first sn store, the
data stores, and the second sn store appear to the reader in the
mentioned order.

The sn loads and stores must be atomic, but the data loads and stores
need not be.

The original seqlock design and implementation was done by Stephen
Hemminger. This is an independent implementation, using C11 atomics.

For more information on seqlocks, see
https://en.wikipedia.org/wiki/Seqlock

bebbf07219 examples/dma: add force minimal copy size parameter
This patch adds force minimal copy size parameter
(-m/--force-min-copy-size), so when do copy by CPU or DMA, the real copy
size will be the maximum of mbuf's data_len and this parameter.

This parameter was designed to compare the performance between CPU copy
and DMA copy. User could send small packets with a high rate to drive
the performance test.

7d3cb76fba examples/dma: fix Tx drop statistics
The Tx drop statistic was designed to be collected by
rte_eth_dev_tx_buffer mechanism, but the application uses
rte_eth_tx_burst to send packets and this lead the Tx drop statistic
was not collected.

This patch removes rte_eth_dev_tx_buffer mechanism to fix the problem.

39b5ab60df dmadev: add telemetry
Telemetry commands are now registered through the dmadev library
for the gathering of DSA stats. The corresponding callback
functions for listing dmadevs and providing info and stats for a
specific dmadev are implemented in the dmadev library.

An example usage can be seen below:

2192599c75 net/mlx5: fix entry size in construct data ipool
The mlx5_action_construct_data structure memory is managed by ipool
named acts_ipool.

The size of one entry in this ipool is mistakenly defined as size of
rte_flow_hw structure.
This size is used to reset in the allocated part. When the size is
incorrect it resets memory that does not belong to it.

This patch defines the correct size.
