Add all necessary elements for DPDK to compile and run EAL on
LoongArch64 Soc.
This includes:
- EAL library implementation for LoongArch ISA.
- meson build structure for 'loongarch' architecture.
RTE_ARCH_LOONGARCH define is added for architecture identification.
- xmm_t structure operation stubs as there is no vector support in
the current version for LoongArch.
Compilation was tested on Debian and CentOS using loongarch64
cross-compile toolchain from x86 build hosts. Functions were tested
on Loongnix and Kylin which are two Linux distributions supported
LoongArch host based on Linux 4.19 maintained by Loongson
Corporation.
We also tested DPDK on LoongArch with some external applications,
including: Pktgen-DPDK, OVS, VPP.
The platform is currently marked as linux-only because there is no
other OS than Linux support LoongArch host currently.
The i40e PMD driver is disabled on LoongArch because of the absence
of vector support in the current version.
Similar to RISC-V, 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.

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.

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.

Memory allocator performance is crucial to applications that deal
with large amount of memory or allocate frequently. DPDK allocator
performance is affected by EAL options, API used and, at least,
allocation size. New autotest is intended to be run with different
EAL options. It measures performance with a range of sizes
for dirrerent APIs: rte_malloc, rte_zmalloc, and rte_memzone_reserve.
Work distribution between allocation and deallocation depends on EAL
options. The test prints both times and total time to ease comparison.
Memory can be filled with zeroes at different points of allocation path,
but it always takes considerable fraction of overall timing. This is why
the test measures filling speed and prints how long clearing takes
for each size as a reference (for rte_memzone_reserve estimations
are printed).
