Re: Port to LoongArch architecture for Debian
Hi helmut,
Nice to communicate with you on RPC.
First, helmut means,
I think one of the early bootstrap failures is around libanl/libutil. do you think loong* should ship with those stub libraries or not?
I see that in your rebootstrap fork, you opt for not having libanl/libutil (in a crappy way). that's fine in principle, but check the codesearches to get an idea of how many packages you will have to patch then.the other option is to patch glibc to include those static stub libraries and let it work like before.
The most pressing tasks，
a) create a dpkg bug for the architecture.
b) submit the multilib-multiarch stuff to gcc packaging.
c) figure out how to deal with -lanl/-lutil.
Second, about the employee relations.
zhangjialing@loongson.cn,sangmeng@loongson.cn,zhangdandan@loongson.cn,We are colleagues，our leader is wanghonghu@loongson.cn. And aim to port to loongarch for debian.
Sincerely，thanks for helmut’s suggestions. And I have two questions want to discuss.
One, if bootstrap of debian lastest version need libanl/libutil library?
The other, glibc upstream seems to have encoded the rule: any architecture that is first released as glibc 2.34 or later. In this case, glibc upstream is not available libanl/libutil library.
Whether we want to stick to that or as glibc? Needing to discuss.
Thankfully, debian community and our team all favour with loong64(loong32) for dpkg.
Finally, I need to create a dpkg bug for our architecture as fast as, which is useful for Mr. helmut to pull request about https://salsa.debian.org/helmutg/rebootstrap.
Thanks!

主题: Port to LoongArch architecture for Debian
Hi,
I am an employee of Loongson Technology Co,Ltd.
Port to LoongArch architecture for Debian ,now in the "Downstreaming" section in the port life-cycle according to <https://wiki.debian.org/PortsDocs/New>.
The purpose of this mail wants to discuss the port with the community and send an email to the debian-devel mailing list.
1、Introduction
The LoongArch architecture (LoongArch) is an Instruction Set Architecture (ISA) that has Reduced Instruction Set Computer (RISC) style.
LoongArch has the typical characteristics of RISC. LoongArch instructions are of fixed size and have regular instruction formats. Most of the instructions have two source operands and one destination operand. LoongArch is a load-store architecture; this means only the load/store instructions can access memory the operands of the other instructions are within the processor core or the immediate number in the instruction opcode.
Loongson and LoongArch documentations: https://github.com/loongson/LoongArch-Documentation
2、Links from upstream
Kernel、Gcc、Gdb、Binutils、Glibc、Llvm、Golang have merged by upstream(github) projects and so on.
For examples,
3、#debian-loongarch64 IRC
Have joined the #debian-bootstrap, #debian-ports and other Debian IRC channels. And have created a new #debian-loongarch64 channel.
Thanks！
