I would suggest you to consider using #debian-loongarch if your
management prefer to keep the whole "loongarch" keyword, rather than
accompanied with a detailed 32 or 64 suffix.

Also I'd like to mention that Debian mailing lists prefer plain text
over HTML, and your company email signature declaring it contains
confidential information is not supposed to exist on a mailing list
that its content is intended to be public available.

Hi,pabs
   Nice to receive your reply.
<https://wiki.debian.org/PortsDocs/New>,this document you have initiated and 
contributed which gives us a lot of guidance.
 
The result of the discussion on debian-dpkg is that dpkg architecture is 
loong64,likely,
aarch64 → arm64, x86_64 → amd64
loongarch64 → loong64，loongarch32 → loong32
Detailed info has archived in 
https://lists.debian.org/debian-dpkg/2022/11/msg1.html.

Dpkg architecture of loong64 just determine the name of the software packages.
About the channel of IRC,we agree with the #debian-loongarch64 even more.

Thanks!

I initiated this document and wrote a fair bit of it, with help from
the rest of the Debian community. If it is in any way incorrect or
unclear, that is probably my fault. Feedback and edits are welcome.

The IRC channel (and mailing list) should be named after the
architecture family, not the port itself. I have just clarified this
in the new port documentation. In addition it sounds like from the 
discussion on debian-dpkg that the port will be named loong64.

So I suggest deregistering #debian-loongarch64 and adding #debian-loong.

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.

zhangjial...@loongson.cn,sangm...@loongson.cn,zhangdan...@loongson.cn,We are 
colleagues，our leader is wanghon...@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.
