Many packages have already been adapted for mips64el, but we have not
done a mips64el build. We are interested in supporting both mips64 and
mips64el on Alpine, as well as mips/mipsel. We are not presently interested
in mips64r6 or mips32r6, as they use different bytecode.
We are *especially* interested in supporting Loongson on mips64el, but
it is not so easy for us to acquire hardware to test with. Our builders are
based on 16-core Cavium Octeon3 CPUs at present, but it would be nice
to have some Loongson hardware in the mix as well.
The main blocker for Docker right now is that several dependencies of
Docker assume that mips is 32-bit O32 ABI. We are working on solving
these dependencies so we can begin producing Docker images and
enabling CI.
Your help with this would be appreciated, as well as a reliable source of
Loongson hardware. Those are the main things we would need to be
able to support Loongson effectively in Alpine.
Thanks,
Ariadne
Re: alpine is not support mips64el platform on apk packages source
Hi Ariadne，
I am very glad to receive your reply, thanks very much.
We are willing donate Loongson machines to alpine community and we have donated machines to the community which make docker official images. Please list the specification of machine you need，tell us the donation process and mailing address.
The kernel built by the community's raw code cannot be run directly on our machine, because some of our patches have not been submitted to the community. We can preset 4.19 kernel binaries for you. Please tell me any requirements for the operating system software and version, we will do our best to meet you.
In addition, we have docker-ce 18.06 and alpine docker images version 3.9 and some apk packages, which might be provided to you for enabling CI.
Thanks!

Regarding coordination of the Loongson build hardware, we will need to sit
down and figure out who would be the best person to handle maintaining it.
Please stay tuned on that, we will get back to you.

We would prefer to have patches, so that we can build official Alpine kernels
for Loongson based on current sources.

Right now our Octeon3 builders are running on a 4.9 kernel provided by Cavium.
We can do the same with Loongson for now, but for the port to be truly viable
in the long-term we would need to get these patches upstreamed as quickly as
possible. The Alpine community can help with this by providing feedback on
the kernel patches to you and also to upstream kernel developers as you submit
them, since we can verify that the patches have been tested on real hardware
by us.

I think the main goal right now would be to bootstrap mips64el. Then we can
install the image on Loongson hardware from there. This is something I can
work on after 3.12 release is done. Sound good?

We are willing to maintain or contribute on mips64el. We will follow this issue.

We have no version 4.9 kernel, alternative kernel 4.19 or 5.4 is OK?

Thanks very much for your kind mind on kernel patches.

We agree with your plan. Our goals are the same on a certain degree.
