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
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
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
