Dear team,

The following patch set is intended to support DPDK running on LoongArch
architecture.

LoongArch is the general processor architecture of Loongson Corporation
and is a new RISC ISA, which is a bit like MIPS or RISC-V.

The online documents of LoongArch architecture are here:
    https://loongson.github.io/LoongArch-Documentation/README-EN.html

The latest build tools for LoongArch (binary) can be downloaded from:
    https://github.com/loongson/build-tools

v6:
    - place some blocks for LoongArch in a pseudo alphabetical order
    - remove some macros not used
    - update release notes in the correct format
    - remove some headers for LoongArch, including msclock, pflock and
      ticketlock, which are now non-arch specific
    - rename some helpers to make them more readable 
    - remove some copied comments
    - force-set RTE_FORCE_INTRINSICS in config and remove non-arch
      specific implementations
    - fix format errors in meson file reported by check-meson.py
    - rebase the patchset on the main repository

v5:
    - merge all patches for supporting LoongArch EAL into one patch
    - add LoongArch cross compilation document and update some documents
      related to architecture
    - remove vector stubs added for LoongArch in net/i40e and net/ixgbe
    - add LOONGARCH64 cross compilation job in github ci

v4:
    - rebase the patchset on the main repository of version 22.07.0

v3:
    - add URL for cross compile tool chain
    - remove rte_lpm_lsx.h which was a dummy vector implementation
      because there is already a scalar implementation, thanks to
      Michal Mazurek
    - modify the name of compiler for cross compiling
    - remove useless variable in meson.build

v2:
    - use standard atomics of toolchain to implement
      atomic operations
    - implement spinlock based on standard atomics

*** BLURB HERE ***

Min Zhou (7):
  eal/loongarch: support LoongArch architecture
  net/ixgbe: add vector stubs for LoongArch
  net/memif: set memfd syscall ID on LoongArch
  net/tap: set BPF syscall ID for LoongArch
  examples/l3fwd: enable LoongArch operation
  test/cpuflags: add test for LoongArch cpu flag
  ci: add LOONGARCH64 cross compilation job

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.

+Cross compiling DPDK for LoongArch
+==================================
+
+This chapter describes how to cross compile DPDK for LoongArch from x86 build
+hosts.
+
+.. note::
+
+    Due to some of the code under review, the current Linux 5.19 cannot boot
+    on LoongArch system. There are still some Linux distributions that have
+    supported LoongArch host, such as Anolis OS, Kylin, Loongnix and UOS. These
+    distributions base on Linux kernel 4.19 supported by Loongson Corporation.
+    Because LoongArch is such a new platform with many fundamental pieces of
+    software still under development, it is currently recommended to cross
+    compile DPDK on x86 for LoongArch.
+
+
+Prerequisites
+-------------
+
+Ensure that you have all pre-requisites for building DPDK natively as those
+will be required also for cross-compilation.
+
+Linux kernel
+~~~~~~~~~~~~
+
+Make sure that LoongArch host is running Linux kernel 4.19 or newer supported
+by Loongson Corporation. The support for LoongArch in the current Linux 5.19
+is not complete because it still misses some patches to add for other
+subsystems.
+
+GNU toolchain
+-------------
+
+Obtain the cross toolchain
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The build process was tested using:
+
+* Latest `LoongArch GNU toolchain
+  <https://github.com/loongson/build-tools/releases/download/2022.08.11/loongarch64-clfs-5.1-cross-tools-gcc-glibc.tar.xz>`_
+  on Debian 10.4 or CentOS 8.
+
+Alternatively the toolchain may be built straight from the source via CLFS, to
+do that follow the instructions on `CLFS for LoongArch64
+<https://github.com/sunhaiyong1978/CLFS-for-LoongArch>`_ github page.
+
+To download cross tools from github we can use the following command:
+
+.. code-block:: console
+
+   wget -P /tmp/ https://github.com/loongson/build-tools/releases/download/2022.08.11/loongarch64-clfs-5.1-cross-tools-gcc-glibc.tar.xz
+
+Unzip and add into the PATH
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After downloading the cross-tools file, we need unzip and add those executable
+binaries into the PATH as follows:
+
+.. code-block:: console
+
+   tar -xvf /tmp/loongarch64-clfs-5.1-cross-tools-gcc-glibc.tar.xz -C <cross_tool_install_dir> --strip-components 1
+   export PATH=$PATH:<cross_tool_install_dir>/bin
+
+
+Cross Compiling DPDK with GNU toolchain using Meson
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To cross-compile DPDK for generic LoongArch we can use the following command:
+
+.. code-block:: console
+
+   meson cross-build --cross-file config/loongarch/loongarch_loongarch64_linux_gcc
+   ninja -C cross-build
+
+Supported cross-compilation targets
+-----------------------------------
+
+Currently the following target is supported:
+
+* Generic LoongArch64 ISA: ``config/loongarch/loongarch_loongarch64_linux_gcc``
+
+To add a new target support, a corresponding cross-file has to be added to
+``config/loongarch`` directory.

      =======================================================
 
+* **Added initial LoongArch architecture support.**
+
+  Added EAL implementation for LoongArch architecture. The initial devices
+  the porting was tested on included Loongson 3A5000, Loongson 3C5000 and
+  Loongson 3C5000L. In theory this implementation should work with any target
+  based on ``LoongArch`` ISA.

Similar to RISC-V, the current version for LoongArch do not support
vector. Re-use vector processing stubs in ixgbe PMD defined for PPC
for LoongArch. This enables ixgbe PMD usage in scalar mode on
LoongArch.

The ixgbe PMD driver was validated with Intel X520-DA2 NIC and the
test-pmd application, l2fwd, l3fwd examples.
