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
Could you confirm which sources have been used to generate it? and
instructions to compile it?
Only the cross compiler [1] is required. The instructions can be found in
the new added file cross_build_dpdk_for_loongarch.rst. I had added the
CI job for cross compiling DPDK for LoongArch in patch v7 7/7. The CI job
can run successfully if without the GCC warning caused by vhost.
v7:
- rebase the patchset on the main repository
- add errno.h to rte_power_intrinsics.c according with
commit 72b452c5f259
Thanks, I will look at this last revision.
There is still one aspect that is unclear to me.
How will the DPDK community make sure changes won't break this
architecture? (I mean, runtime checks, not only compilation)
IOW, what do you plan to hook to our CI to test patches submitted to
the mailing list?
We can send our machine to UNH lab, but it may take a long time.
GHA seems to be a good choice. However, I found that the codes of CI
runner of GHA [2] are arch-specific. So the CI runner currently cannot
run on
LoongArch machine.
Are there other CI clients which are not arch-specific and can be used
for DPDK?
We can provide machines accessible by the public network. These machines run
Loongnix-server system which was built based on the source rpms of CentOS 8.
We can deploy DPDK CI client on these machines.
