finding RISC-V packages in standard repositories might prove problematic.
Gentoo would be ideal.

Idk, sounds too risky.

Can anyone explain the significance of this? I’m pretty technology-literate, but I am not seeing a big advantage of this over a Linux machine? Genuinely curious.

RISC-V is a set of instructions implementable to processors that do not need licensing fees and controlling restrictions imposed. Due to its reduced instruction set; it uses less power in general but is harder to write compilers that work on it.
Having it more popularised opens up the doors for more enthausists to enter developing with it.
stardreamer@lemmy.blahaj.zone 6 months ago
Harder to write compilers for RISC? I would argue that CISC is much harder to design a compiler for.
That being said there’s a lack of standardized vector/streaming instructions in out-of-the-box RISC-V that may hurt performance, but compiler design wise it’s much easier to write a functional compiler than for the nightmare that is x86.

If that is true I don’t think it can be attributed to it being RISC
turbowafflz@lemmy.world 6 months ago
This still runs Linux, or whatever else you want to run, it just has a RISC-V CPU instead of an x86 or ARM one
nossaquesapao@lemmy.eco.br 6 months ago
One of the implications is the development and popularization of the RISC-V architecture, which is open and can open the market for more competition and less monopolies, among other things.
ShittyBeatlesFCPres@lemmy.world 6 months ago
RISC-V is an open source chip design. As of today, it’s still worse than x86 (a CISC—“complex instruction set” design) and ARM (a proprietary RISC—“reduced instruction set” design) but if history is any indication, open source will end up overtaking them in the same way that, for instance, 98% of supercomputers today run highly customized versions of Linux.
There’s also some political connotations surrounding it because some countries don’t want high-end chip designs to be available to their perceived competitors (whether for protectionism reasons or military reasons) but it doesn’t matter.
ShittyBeatlesFCPres@lemmy.world 6 months ago
More info for anyone who wants it:
Linux, being open, can already run on RISC-V while Windows ARM laptops are only really coming out now. Not sure if they have plans for RISC-V. Apple has long used ARM in phones and now their M chip laptops. Reduced instruction sets tend to have better battery life and (originally) worse performance so were ideal for mobile but over time, Intel/AMD (x86) and ARM (basically all mobile chips) have borrowed ideas from each other. So, Apple’s ARM chips can be powerful and Intel/AMD chips can be power efficient if that’s the goal.
So, the main advantage of RISC-V is that there’s no royalties or, in some cases, the baggage of aging designs that need backwards compatibility. RISC-I was originally designed as a teaching tool for universities that didn’t want to pay royalties for student toy models and wasn’t really a corporate thing. RISC-V is (the fifth version as the Roman numeral V implies), got good enough to be useful in the real world. And now there’s a consortium of companies funding it and hoping to one day not have pay royalties to make chips.
So, there’s a lot of momentum behind RISC-V. It could easily be the primary architecture someday or, if nothing else, reduce the royalty rates of the other architectures.

It is a Linux machine. Runs a Debian derivative, and it’s not like Windows or anything else that isn’t Linux/BSD can run on a RISC-V laptop.
This isn’t the first RISC-V laptop, but the significance of a RISC-V laptop existing is primarily for developers who work on software targeting RISC-V systems. The ability to run RV64 programs without emulation and to natively compile RV64 software without cross-compilers is valuable to some people. Also, China in particular sees value in having computing products that aren’t affected by sanctions; the processor in this is designed and manufactured by a Chinese company without licensing any intellectual property from US or UK.
Explaining what RISC-V is
RISC-V is a relatively newer CPU instruction set architecture that competes with x86 (Intel, AMD) and ARM (Qualcomm, Ampere, MediaTek, etc.). Its current designs don’t really match those two in general-purpose performance yet but has the distinction of being a free, open, and extendable standard. Whereas x86 has only two CPU vendors and ARM has many vendors who all need to pay per-core license fees to ARM Holdings and have limits imposed on what they can do to it, RISC-V processors can be made by any hardware vendor with the means to make a processor and can be custom-designed to better fit specialized use-cases. Its use in general-purpose CPUs is catching on fastest in China but it sees use across the world in academia and in special-purpose processors by companies like Western Digital.

RISC-V is a CPU architecture, like AMD64 or ARM. You can run Linux on it.
hoshikarakitaridia@lemmy.world 6 months ago
RISC and CISC are two language which your CPU speaks, and which have different strengths and weaknesses. Reduced Instruction Set Computer vs. Complex Instruction Set Computer. It’s something like Chinese vs. English. Either have a word for everything but that means there is a lot of words to learn, or have a smaller amount of words but that means you need more words to describe what you mean.
Highly technical; both been around for a while, and iirc usually CPUs use CISC, but RISC always retained it’s strengths, so scientists are always looking into the difference in application for both.
Bgl I have no clue why this technology is so newsworthy rn but I know Western countries made a fuss about China activitily pushing the less used RISC architecture.

Yes. You said that many times. :)

I assume you are familiar with what CPU architecture is. The famous one is x86 and ARM. This is just another one of those called RISC-V.
The significance is mostly political. US and allies have been trying to sanction China technologically. They even tried to block export of RISC-V, but since it is open source, they can just get fucked. Now, China can only get sub par GPU and limited CPU. Pushing for RISC-V means China is aiming to further develop it to be as capable as the CPU being sanctioned effectively making the sanction useless and even furthering Chinese manufacturing capabilities in the process.
The big advantage is that this is technically more standardized and free. Unlike ARM which require license, RISC-V doesn’t so anyone can make their own CPU and get the software support already in place. Hopefully more CPU manufacturers will be created from the advancement of RISC-V making more fierce competition.

This feels like another Chinese rip off. The Chinese government want to replace the west with in home stolen ideas.
drmoose@lemmy.world 6 months ago
Stolen ideas? Riscv is open source and a laptop is not exactly some unique intellectual property. You’re just showing your xenophobia here.
rottingleaf@lemmy.zip 6 months ago
Especially since calling a laptop “<some>book” is hardly a civilization-level achievement, hardly even an idea, it’s fashion and I approve of Chinese treating trademarks like this.
I think trademarks and patents should die. We’d see a better world without them, and very quickly.
Coreidan@lemmy.world 6 months ago
China has spent an eternity stealing IP and undermining security by steal top secret info through state sponsored hacking efforts.
They’ve built a strong solid reputation of impeding on personal privacy and doing tons of shady shit at the expense of everyone else.
People have every right to question this and be skeptical of what they are up to because they’ve shown over and over in the past that they cannot and shouldn’t be trusted with anything.
However your mind immediately goes to xenophobia. What a fucking clown.

hark@lemmy.world 6 months ago
I wonder if it’s possible to get a post about technology coming out of China without a “hurr durr they r spy!!1” comment. I don’t see the same every time there’s an article on a new Intel processor, for example.
retrospectology@lemmy.world 6 months ago
Because China is not a normal country and all of its industry is controlled by the state. It desperately wants the world to forget that its the kind of country that runs over its citizens with tanks, forced labor and has hundreds of concentration camps, but it would be kind of silly to go along with that when it has not changed from that course.
Their long-term plan is to slow boil global opinion through a mass social engineering projects and propaganda into accepting that it’s ok and normal for a government to operate in the way that the CCP does.
As long as the CCP is in power anything it does should should be observed about with a healthy dose of suspicion.
GeneralVincent@lemmy.world 6 months ago
The difference is that the CCP has a lot of control over Chinese companies operations.
In the US, the companies have a lot of control over the US government.
Ok that’s an oversimplification, but it sounded good
Septimaeus@infosec.pub 6 months ago
Is it unwarranted? Have Chinese tech companies turned a new leaf in their collective InfoSec practices?
Conversely, has Intel had a history of consumer privacy violations?

Willing to bet money this was posted on hardware that actually does have backdoors to some 3 letter agency in the US, to much more personal consequence than any metaphorical Chinese government spyware
niemcycle@lemmy.world 6 months ago
Yeah that’s exactly the thing, people freak out so much about China having access to their data, but act much less concerned when it comes to their own government potentially having access to said data. One of these options has the ability to affect your life if they don’t like your data, and it isn’t China.
(Not to get me wrong, I think no government should have access to one’s data, moreso pointing out the double standard)
MigratingtoLemmy@lemmy.world 6 months ago
You mean you’re assuming that it will come with a backdoor in the hardware? Will that matter if the bootloader is FOSS?
Pantherina@feddit.de 6 months ago
Like… the Intel ME?? And no BIOS seems to allow the switch to disable it, even though that was literally required after the NSA sued Intel?
