I'm sorry to complete this PR so late. I am busy some time ago. I have only been free now. Thank you very much for your attention!

Let me give you the lowdown once again: Loongarch, also known as Loongarch, is a badass RISC-style Instruction Set Architecture (ISA). It's all the rage in the open-source community and has been rocking long-term support.

There is still the whitespace issue to solve in the bake file. Can you also squash your commits please?

I don’t figure out why there is an assertion failure when using loong64 in debian and ubuntu, and not all versions will do this.
Maybe we can only operate loong64 on the sid version of the hellogo function?

The golang installed is 1.15 does not support loong64 and changed to 1.19

The code you changed is under "buster-backports" condition

When GOARCH=loong64, add prerequisites to the testenv() function to judge the Golang version

It's hard to see how this would be useful in current form. No packages seem to install in debian. No C-based build seems to work in any distro, in debian because packages can't be installed and in old Alpine 3.11 because there doesn't seem to be any supported linker.

Despite most tests being disabled, the CI still looks quite red.

I can't seem to get any packages to install in sid. This may be temporary error, but looks like there are conflicts between architectures.

Eg. difference of versions of gcc-13-base seems to cause issues.

Can I adapt to debian first, alpine is waiting for the official community to start loadarch into the upstream and modify it?

[yzewei]

Due to the fact that the alpine community has not yet accepted the loongarch architecture, I have temporarily removed the build testing under alpine. After alpine community receives the loongarch architecture, I will start ci-testing.

It seems that there are some problems with the cargo part of the arm64 and ppc64 architecture test in the debian: sid test. Can you see what the situation is? @tonistiigi
Error: debian:sid
