I'd rather see what RISC-V has to offer.

[-] [email protected] 25 points 4 days ago

As a fellow risc-v supporter, I think the rise of arm is going to help risc-v software support and eventually adoption. They’re not compatible, but right now developers everywhere are working to ensure their applications are portable and not tied to x86. I imagine too that when it comes to emulation, emulating arm is going to be a lot easier than x86, possibly even statically recompilable.

[-] [email protected] 4 points 4 days ago

They’re not compatible

This is what concerns me. ARM could dominate the market because almost everyone would develop apps supporting it and leave RISC-V behind. It could become like Itanium vs AMD64 all over again.

[-] [email protected] 9 points 4 days ago* (last edited 4 days ago)

Well right now most people develop apps supporting x86 and leaves everything else behind. If they're supporting x86 + arm, maybe adding riscv as a third option would be a smaller step than adding a second architecture

[-] [email protected] 6 points 4 days ago

Exactly. Adding a third should be much simpler than a second.

[-] [email protected] 5 points 4 days ago

It greatly depends on the applications.

Porting Windows exclusive games to Linux is a small step as well, but most developers don't do it because they cannot justify the additional QA and debugging time required to port them over. Especially since Linux's market share is small.

The reason Itanium failed was because the architecture was too different from x86 and porting x86 applications over required significant effort and was error prone.

For RISC-V to even get any serious attention from developers, I think they need to have appx 40-50% market share with OEMs alongside ARM. Otherwise, RISC-V will be seen as a niche architecture and developers would avoid porting their applications to it.

[-] [email protected] 1 points 4 days ago* (last edited 4 days ago)

We agree.

My point is that “porting” is not such a big deal if it is just recompile. If you already target Linux with a portable code base ( to support both ARM and amd64 for example ) then the burden of RISC-V is pretty low. Most of the support will be the same between RISC-V and ARM if they target the same Linux distros.

The Linux distros themselves are just a recompile as well and so the entire Open Source ecosystem will be available to RISC-V right away.

It is a very different world from x86 vs Itanium with amd64 added to the mix.

Look at Apple Silicon. Fedora already has a full distribution targeting Apple Silicon Macs. The biggest challenges have been drivers, not the ISA. The more complete the Linux ecosystem is on ARM, the easier it will be to create distros for RISC-V as well.

Porting Windows games to Linux is not a small step. It is massive and introduces a huge support burden. That is much different than just recompiling your already portable and already Linux hosted applications to a new arch.

With games, I actually hope the Win32 API becomes the standard on Linux as well because it is more stable and reduces the support burden on game studios. It may even be ok if they stay x86-64. Games leverage the GPU more than the CPU and so are not as greatly impacted running the CPU under emulation.

[-] [email protected] 2 points 4 days ago

That is a risk on the Windows side for sure. Also, once an ISA becomes popular ( like Apple Silicon ) it will be hard to displace.

Repurposing Linux software for RISC-V should be easy though and I would expect even proprietary software that targets Linux to support it ( if the support anything beyond x86-64 ).

Itanium was a weird architecture and you either bet on it or you did not. RISC and ARM are not so different.

The other factor is that there is a lot less assembly language being used and, if you port away from x64, you are probably going to get rid of any that remains as part of that ( making the app more portable ).

[-] [email protected] 1 points 3 days ago

Apple Silicon isn't an ISA, it's just ARM, what are you saying?

[-] [email protected] 1 points 3 days ago

Once a chip architecture gets popular on Windows, it will be hard to displace. ARM has already become popular on macOS ( via Apple Silicon ) so we know that is not going anywhere. If ARM becomes popular on Windows ( perhaps via X Elite ), it will be hard to displace as the more popular option. That makes RISC-V on Windows a more difficult proposition.

I do not think that RISC-V on Linux has the same obstacles other than that most hardware will be manufactured for Windows or Mac and will use the chips popular with those operating systems.

[-] [email protected] 1 points 3 days ago

I think you missed the forest for the trees my friend. I was simply commenting on the fact you made it sound like Apple Silicon is it's own ISA.

Ok, no shot the title doesn't contain "arm wrestle" on purpose..

[-] [email protected] 9 points 4 days ago

It literally has a picture of arm wrestling on there. I think it's on purpose.

[-] [email protected] 4 points 4 days ago

I feel like linux users benefit the most from arm since we can build our software natively for arm with access to the source code.

[-] [email protected] 38 points 5 days ago
[-] [email protected] 22 points 5 days ago

Until risc-v is at least as performant as top of the line 2 year old hardware it isn’t going to be of interest to most end users. Right now it is mostly hobbyist hardware.

I also think a lot of trust if being put into it that is going to be misplaced. Just because the ISA is open doesn’t mean anything about the developed hardware.

RISC-V is currently already being used in MCUs such as the popular ESP32 line. So I'd say it's looking pretty good for RISC-V. Instruction sets don't really matter in the end though, it's just licensing for the producer to deal with. It's not like you'll be able to make a CPU or even something on the level of old 8-bit MCUs at home any time soon and RISC-V IC designs are typically proprietary too.

It doesn’t usually work that well in practice. I have been running an M1 MBA for the last couple years (asahi Arch and now Asahi Fedora spin). More complex pieces of software typically have build system and dependencies that are not compatible or just make hunting everything down a hassle.

That said there is a ton of software that is available for arm64 on Linux so it’s really not that bad of an experience. And there are usually alternatives available for software that cannot be found.

[-] [email protected] 9 points 5 days ago

Long time Raspberry Pi user here, the only software I can't load natively is Steam. What software are you having problem with on the M1?

[-] [email protected] 6 points 5 days ago

Electron apps using older versions that don't support the 16k page size are probably the biggest offenders

[-] [email protected] 11 points 5 days ago
[-] [email protected] 2 points 5 days ago

I can't say I'm one who shares that sentiment seeing as the only two projects I'm involved with happen to be Electron based (by chance rather than intention). Hell, one of them is Pulsar which is a continuation of Atom which literally invented Electron.

[-] [email protected] 6 points 5 days ago

Couldn't we do that with x86?

[-] [email protected] 25 points 5 days ago* (last edited 5 days ago)

We can. The point is that Windows users can't compile for arm. They depend on the Dev to to it. That will take some time and some won't do it at all.

For me, arm has already "won" this debacle -- convenience > performance all day errday.

[-] [email protected] 30 points 5 days ago

ARM won the mobile/tablet form factor right from the start. Apple popularised ARM on the desktop. Amazon popularised ARM in the cloud.

Intel's been busy shitting out crap like the 13900K/14900K and pretending that ARM and RISC-V aren't going to eat their lunch.

The only beef I have with ARM systems is the typical SoC formula, I still want to build systems from off the shelf components.

I can't wait.

I'm here with you. ARM and RV could really go into standardization.

[-] [email protected] 3 points 4 days ago

Thinking about it, the SoC idea could stop at the southern boundary of the chipset in x86 systems.

Include DDR memory controller, PCI controller, USB controllers, iGPU's etc. most of those have migrated into x86 CPU's now anyway (I remember having north and south bridge chipsets!)

Leave the rest of the system: NIC's, dGPU's, etc on the relevant busses.

Does this possibly mean the end of x86 or will it be a coexisting scenario?

I still believe that as much as some people bark on about, X86 will not die for a long time, it will still keep kicking for some time.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
