raw/ifpga: introduce AFU driver framework
AFU (Acceleration Function Unit) is part of FPGA and enumerated
by ifpga driver.
This driver implements common AFU device interfaces and exposes
them to application as standard raw device APIs.
Normally application can operate specified AFU as below,
1. call rte_rawdev_pmd_get_named_dev() to find AFU device.
2. call rte_rawdev_configure() to initialize AFU device.
3. call rte_rawdev_selftest() to test AFU device.

When passing in test names to run via either the DPDK_TEST environment
variable or via extra argv parameters, the checks run on those commands
can miss valid commands that are registered with the cmdline library in

"dump_*" set of commands are not callable via argv parameters, but can
be called manually.
To fix this, just use the commandline library to validate each command

The cmdline library cmdline_parse() function parses a command and

also uses this function to validate commands, meaning that there is no

To fix this omission, we extract the body of cmdline_parse into a new
static inline function with an extra parameter to indicate whether the
action should be performed or not. Then we create two wrappers around
that - a replacement for the existing cmdline_parse function where the
extra parameter is "true" to execute the command, and a new function
"cmdline_parse_check" which passes the parameter as "false" to perform
cmdline validation only.

dev->data->dev_private, and then tries to free PRIV(dev)->intr_handle,
which causes the heap use after free issue.
The free can be moved to before the release function is called.

net/ena: add device argument to disable LLQ
The PMD attempts to enable the LLQ (Low Latency Queue) whenever it's
possible. The LLQ requires the user to enable the Write Combining for
the supported igb_uio/vfio-pci modules.
The vfio-pci module officially doesn't support the WC. Moreover, in some
Linux distributions, it can be built into the kernel, so any
modifications to the vfio-pci module require a full rebuild of the
kernel. This can make the configuration process much harder and for some
users, that are not interested in the great network performance for
their setups, it may be redundant. These users requested to be able to
turn off LLQ to avoid the hassle of such a setup.
It's generally not recommended to disable the LLQ, as it won't result in
the performance improvement and on the 6th generation AWS instances the
lack of LLQ can have a huge negative impact on hardware performance.
The device argument which controls the LLQ is called 'enable_llq` and by
default, it's set to 1 (which means that the LLQ is enabled). Setting
it to 0 disables the LLQ.
This commit also adds the explicit initialization of the devarg for the
'use_large_llq_hdr'. The PMD_REGISTER_PARAM_STRING() call for the ENA
was updated with all the available devargs (including
ENA_DEVARG_MISS_TXC_TO, which wasn't added previously).

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.

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.

associated vfio_cfg) and binding the group to it.

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.

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.
