LoongArch "Loong64" Added To Debian Ports

[rmfx]

I am against this unnecessary ISA that brings nothing else than "It's Chinese made!" to the equation... (and it's not in reality)

One more plateform to fragment even more, one more plateform to duplicate efforts evn more, one more plateform to decrease the RISC-V attention.
If they wanted to please ARM and Intel by weakening the competition, they wouldn't have chosen better than pushing for this useless alternative.

Competition is good actually

Competition between the market leaders is good, not competition between the underdogs…

It really isn't a new ISA though, it is just a superset of MIPS64. Most of the work has already been done. For a long, long time...

China is only officially supporting Deepin/UOS and Kylin, though. And yes, both of them go back to Debian underneath, but they could've added support without Debian, too. So I don't see the real benefit here, unless they want to start selling LoongArch in other countries.

Not really.
Currently, loongarch64 is officially supported by Gentoo, while the loongarch64 ports of ArchLinux and slackware are available now.

In fact, China is developing multiple ISA CPUs in parallel, including:
X86 (Hygon, Zhaoxin),
ARM (Hisilicon, Phytium, Rockchip, Unisoc, ...),
MIPS (CPI, Ingenic),
RISC-V (Alibaba, CAS),
SW (ShenWei),
Loongarch (Loongson).

Loongson is just a small part of the industry.
"China" should not be regarded as the will of a single individual, but as a huge collection.

By the way, I got my Loongson 3A6000 EVB Board recently.
It currently runs Archlinux and works fine!

For RISC processors, ISA is only a small part of the picture.
The specific implementation of the processor lies on its microarchitecture, and MIPS does not have such a high-performance microarchitecture as the Loongson 3 series.
Also, Loongarch64 does a lot of work with SIMD and binary translation. These are not things that the MIPS64 has, and Loongarch64 doesn't have a Delay Slot either.

Yes, there is a huge difference between LoongArch and MIPS, when they developed MIPS they were ready to do without MIPS, LoongArch supports the Mips part of the functionality as he supports x86/arm/riscv is the same idea, which is to use binary translation to work. But with MIPS becoming less popular, some of the features LoongArch supports for MIPS may never be developed. While LoongArch's support for X86 programs is now well established and can even play thousands of win games, ARM support will be released after X86 matures.
None of these functions are available to MIPS, and CIP has no ability to do them, only LoongSon wants to do them.
