Dear team,
The following patch set is intended to support DPDK running on LoongArch
architecture.
LoongArch is the general processor architecture of Loongson and is a new
RISC ISA, which is a bit like MIPS or RISC-V.
The online documents of LoongArch are here:
https://loongson.github.io/LoongArch-Documentation/README-EN.html
The latest cross compile tool chain can be downloaded from:
https://github.com/loongson/build-tools
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
Min Zhou (24):
