Well, that's what you get when you can do nation-state planning with an event horizon measured in decades, practically infinite cash and with the ruthlessness to engage in corporate espionage plus the total elimination of political campaigning (because you're the CCP, the only gang in town).
In contrast, Western corporate execs have an event horizon between "next quarterly reports" and "vesting/bonus period", additionally in any sufficiently large organizations you will have fiefdom fights that are counterproductive to the company at large, and Western politicians can only think to "next important election", so basically a few months as well because there is always an election going on in some state or local division.
We have gotten societally incompatible with not just coming up with new ideas, but with maintaining what we already have. It's like in 1984 - we can't even think of such timeframes any more.
And no, I'm not calling for a dictatorship. I'm rather calling for dissolution of the stock market for speculation, and for consolidating elections to once every four years so that politicians have time to cool down from the constant campaign hype pressure.
Yes, and that machine was exceptionally good; by far the best laptop i ever owned: mate screen, good keyboard, small and lightweight for the time, and exceptionally open and well supported for Linux despite being a mips arch. I would gladly get myself another one if I could.
comes a long way.. they have some pc models sell in china but i guess only IT dev people would give it a try. china is pushing the state-owned companies and civil servant to use linux (some linux distro build by china company and replace windows and all America product) and the china-build CPU, but LooongArch also seems is not the #1 choice. I hope they can chooose LoongArch and built some debian based OS to use. This would be a 100 millon user market..
Also seems russia is interested to do some stuff based on LoongArch
just found one on JD: 14inch, LoongArch 3A6000, 16G mem, 512G storage, 4G GPU storage, sold for 6499RMB around 920USD
I briefly owned one of the first Loongson netbook laptops, the Lemote I believe it was nicknamed. I've always been very much into open hardware, so I picked one up as soon as I could.
And I believe Debian was the only distro I was able to run on it back then too. Also NetBSD.
I ended up giving it to someone at the local hacker space. It's fun to try but it's not a daily driver.
Didn't Stallman use one as daily driver for a while?
Actually Alpine had support for LoongArch64 well before Debian - I have it running on my machine. Works fine expect for support for the integrated GPU.
That's a long way and congrats to the Longson team!
My college friend participated in the Google Summer of Code 2009, migrating openSUSE to MIPS. The CPU they used was an earlier version of Longson (forgot which one).
You can just buy them off AliExpress, I've got myself a 3A6000 board from there - it's an interesting machine, feels much like a (UEFI) PC and is sure faster than any readily available ARM SBC, about the level of Zen1 I'd say.
Not sure how they compare exactly. And of course it never hurts to have two players in the game.
I just meant I've heard a lot more about stuff going on in the RISC-V field in China. A lot of it is focused on the embedded stuff yes but not only there.
Wow man. Back in the day the Godson processors were supposed to be these MIPS chips from China that ran Linux. I wanted one just for the sheer curiosity of it all but couldn’t get one here in the US.
I wonder if there is a way to get them from Taiwan / Korea. I can’t go to mainland China.

If the architecture is still undocumented, I would not consider Debian’s move to be wise.
Always thought they’d ship me garbage. Not sure why. I’ve bought lots of stuff there. But I don’t know how to tell it’s not some rebadged Via chip before it arrives. Just the game, I suppose. To Aliexpress!
Once I used an old MIPS debian in qemu to test big endian. I thought since LoongArch has its root in MIPS it may be big endian. It turns out "LoongArch bit designations are always little-endian".

Right on time
Loongson (the company) have been around since 2001.
Loongarch (the ISA that debian is now supporting) has only been around since 2021. Previously Loongson used MIPS and another ISA known as LoongISA.
> Loongson used MIPS
Stallman actually daily drove a Loongson MIPS-based notebook for a while.
I thought they pivoted to RISC-V

Nah it's much easier to move fast if you don't rely on a committee.

You talk about "western" politicians, but this point feels like it only really applies to the US with its ridiculous two-year cycle.

The big tech companies ran without profit for a long time. People worried a lot about that but they did it anyway.

Didn't Richard Stallman use a Lemote Loongson computer before?
https://stallman.org/stallman-computing.html
Yes, and that machine was exceptionally good; by far the best laptop i ever owned: mate screen, good keyboard, small and lightweight for the time, and exceptionally open and well supported for Linux despite being a mips arch. I would gladly get myself another one if I could.

I think the process is very far behind the 3nm used by Intel and ARM SOC makers, so performance per watt will take a hit.
For the curious:

Huh. Is this arch supported by LLVM/Rust?
It was announced recently (https://lwn.net/Articles/1044496/) that Apt, the Debian package manager, would require Rust by May 2026.
It does look like LoongArch is a supported target of Rust at Tier 2: https://doc.rust-lang.org/beta/rustc/platform-support/loonga...
In fact, Rust's targets page is much bigger than I remembered! Good work
That's a long way and congrats to the Longson team!

You surely meant to write "a loong way", right?
Are Loongson powered machines available in the west? Are they only available from Chinese manufacturers?
You can just buy them off AliExpress, I've got myself a 3A6000 board from there - it's an interesting machine, feels much like a (UEFI) PC and is sure faster than any readily available ARM SBC, about the level of Zen1 I'd say.
Interesting, I thought performance was lower than zen 1. I wonder if they'll ever catch up
Hasn't RISC-V kinda taken its place by now?
Are there RISC-V chips with comparable performance for desktops and laptops on the market?
I thought so, yes: https://www.theregister.com/2025/03/05/china_alibaba_risc_v_...

You can buy LoongArch hardware on AliExpress, for example.
