This is super great. The biggest pain point of Asahi Linux is how it doesn't have GPU acceleration on M3 and newer, especially now that M6 is out!

However, Asahi Linux has a strictly no-AI policy [1]. So this great work can't be upstreamed. I expect to see a bunch of AI-assisted forks that get things working smoothly on newer hardware to dominate as most people just care about getting stuff working, while only a handful of purists stick to the non-AI version running on ancient hardware.

Nvidia's kernel module is open source these days, it's the usermode stack that's still closed.

yonatan8070 5 hours ago | parent

Even though the kernel module is open-source (sort of, development still happens behind closed doors), it's still an out-of-tree module, rather than being built into the kernel, which would give you as smooth an experience as with AMD or Intel, who's GPUs literally do just work on any distro with no fuss.

It’s never gonna be a smooth experience with Linux on Macs, because of installation, but also firmware upgrades etc. there’s always some manual steps involved and nothing will change unless Apple itself starts supporting Linux natively

zamadatix 13 hours ago | parent

Asahi's long term goal is to get everything possible merged into the (actually) upstream projects anyways so any distro can just work. It'd be nice to see that continue rather than have forks on forks for the sake of singular differences (and it looks like proper upstreaming is what they are going after per the Remaining Work section).

This may never end up working like that, considering how complicated installation is, comparatively speaking, and how macOS is still pretty much required to be installed.

You can make the Linux installation on Apple Sillicon Macs pretty painless nowadays. One terminal command on macOS, reboot to Linux, run one script - voila.

Yeah, but it's unlikely such installers will be officially supported by the distributions, which was my point regarding upstreaming.

It's extremely impressive that they were able to make a working driver so quickly. I think this is one of the best use cases for LLMs. You don't need someone to spend years reverse engineering undocumented hardware anymore. It will interesting to see how good the driver the LLMs came up with is, and whether it can be upstreamed into the Linux kernel.

Might be one of the only use cases where LLMs are necessary to succeed. Can't imagine the pain of reverse engineering a technology of this scale and "secrecy".

Traditional hardware RE centers around heroics by a small number of very smart people, see: marcan, Alyssa Rosenzweig, Asahi Lina, etc. What they did is insanely impressive, and given how hard it was with LLMs I'm sure I would not personally be able to do this work without LLMs. That said, I'm looking forward to a world where the staring at hexdumps and traces can be delegated to LLMs and talented humans can spend their time building as opposed to head banging.

The problem I’m finding, at least with today’s models, is that it produces disposable software. It’s not good at making well-architected, durable software. Stuff that could be maintained and bug-fixed.

I mean you can get good stuff out of it if you know what you are doing and guide it, but if you just say “here’s a regression suite. Write an implementation that passes” you will get something that works for a while but ages quickly and will need to be thrown away.

teaearlgraycold 12 hours ago | parent

With today’s technology I’d still want a GPU driver developer guiding the LLM rather than some rando who is out of their element. But cutting down the exploration cycle time and giving the developer massive parallelism (have 10x agents exploring different hypotheses or features) is the real win. We don’t need to skip all the way to slop just to squeak out a little more effort savings.

Great observation, two things:

- During my time at Apple I never saw any of the macOS source code, at all, even for userspace components. I had not even heard of things like SPTM.

- I have not worked there since June 2025

I don't believe that there's any risk due to my former Apple employment. As another example, WINE does not ban all former Microsoft employees, they just ban anyone who has ever looked at the Windows source code. If I felt there was even a chance that my employment at Apple may have exposed me to relevant internal secrets, I would refrain from contributing to community projects.

The only cost was a month of llm usage. If the legal questions matter to you, you or someone else should be able to spend some tokens to redo their work in a similar way. I doubt Apple will actually care much about this. But even if they do, the worst they’ll do is get the repo taken down.

It may also be legal to do the following: 1. Have an llm read all the code these people have written and produce extensive documentation. 2. Have another llm consume that documentation and write another working driver. I am not a lawyer but I think this may fall under fair use, because reverse engineering is allowed for interoperability.

Apparently. But Apple should be ashamed of themselves for that fact. What are they so afraid of? That Mac OS is so inferior to Linux that if they publish specs so that a driver can be made, that everyone will wipe Mac OS off their disks like it's Windows ME??

Once again, modern Apple is allergic to competing on their product's merits, clinging to force as though it's the only way anyone will choose them. Which is insane to me given how loyal their following is. I'm typing this shit on Mac OS right now.

Clean room is not 100% legally necessary for RE, but I would never touch an LLM to do RE work when there's even a chance the models have been trained on the thing I ultimately plan to reimplement.

Furthermore, given that Asahi Linux, the biggest game in town when it comes to running Linux on Apple silicon, is trying to be cleanroom, it is incredibly rude of you to not mention LLMs until after showing a page full of LLM-derived firmware ABI. This is a trap for anyone who's trying to be cleanroom.

I have many frustrations with LLMs, mainly around the type of user whos brain shuts down, but Apple would be walking a very fine line if they offer a service that they also will sue you for using.

Perhaps they should have used the Foundation Models to build their code. Really put Apple in a difficult position.

That's what's referred to as a "clean room implementation" further up the thread.

However, this specific thread is about the scenario where an employee has inside knowledge and is passing that knowledge on to the implementer.

Legally speaking, a clean room implementation has much better defenses from claims of copyright violation.

danielheath 9 hours ago | parent

> NDAs apply to all of humanity

The NDA doesn't apply to people who haven't signed it, but copyright law does. If you know the material you're receiving is under copyright (eg proprietary source code), and you publish work based on that copyright material, the fact that it's now widely available is not an effective defense against claims of copyright violation.

Person B in this scenario hasn't violated the NDA, but they could be sued for copyright infringement.

Dylan16807 4 hours ago | parent

The point of a clean-room implementation is that the only thing passing from A to B is a detailed specification written from scratch, because functional details cannot be copyrighted.

Which I think you know, so I don't understand your argument.

You said in another comment "However, this specific thread is about the scenario where an employee has inside knowledge and is passing that knowledge on to the implementer."

It being proprietary and/or secret information doesn't affect the copyright of the clean-room output. If there's trade secret implications those are worth discussing, but as a separate issue.

Wasn’t that exactly the legal standard Compaq had to prove when they did a clean room implementation of the IBM BIOS?

st_goliath 11 hours ago | parent

The argument is not esoteric. An Apple employee working on a reverse engineered GPU driver might (intentionally or not) incorporate internal knowledge that they are contractually obligated to keep secret or write an implementation that is too close to proprietary code they had access to, to the point that it could be argued that it is a derived work.

This sort of thing has always been a concern for projects that re-implement some existing piece of software, e.g. there were concerns early on during development of the GNU project about people contributing after having been exposed to Unix source code. Similarly, it is an ongoing concern for the Wine project[1], as well as ReactOS. The later even had a code freeze and internal audit in 2006, after allegations came forward that code had been derived from disassembled Windows binaries[2].

It's because it doesn't matter how copyrighted material ends up in a project. If an LLM reproduces copyrighted material (which is very hard to verify) then the lawsuit from the copyright owner can still sink even robustly funded projects.

The fact is, open source has much more liability than closed source software does. If copyrighted material ends up inside a private code base it'll be nearly impossible for the owner to discover that and sue.

Because if it's feasible for any company with a war chest to start a court case about a competitor maybe having a matching line of code to theirs via an LLM, then basically every single company with a warchest would be at war with eachother, because they're all using LLMs.

Business and code production would grind to a halt whilst basically every big tech company shares it's entire codebase with every other tech company for discovery. It's basically MAD.

And if it was feasible, given we've had a couple of years of all the big tech companies heavily using LLMs, there should be some notable court cases by now, surely?

The lack of modern small airplane designs, especially engines, is the extensive and thus expensive certification process. Most of what is a "new" airplane usually is derived from a very old, grandfathered design.

The only real innovation for small planes is in the electric flight area - when you gotta do a full certification anyway as you're piloting an entirely new drivetrain, you can financially afford to be much more innovative on other parts of the design.

In a case where both parties have lawyers, having more and more expensive lawyers is not necessarily predictive of a case’s outcome. There are diminishing returns.

> concealing that he is a former Apple engineer with direct contacts to the people involved in Apple Silicon development

This is false. I am a former Apple engineer. I did not conceal it (it's the top item of my resume and my LinkedIn and I made my PR from my public Github with my name attached, as opposed to a pseudonym which is expressly allowed by Asahi policy). I also had no exposure, at all, to any internal information or code about macOS, SPTM, or Apple Silicon during my time there.

I also don't have connections to people involved in Apple Silicon development (and I'd add that this does not mean someone cannot contribute, the question is were they exposed to tainted information, which is absolutely not true in my case). I have many friends who work for Apple (I'm a Stanford alum) but none in Apple Silicon directly.

I disagree with the phrasing of this entire thing, but this statement is demonstrably false.

Who volunteers to be the shmuck that fights Nintendo's lawyers in court? Who's funding the defense against Apple?

It's safest to err on the side of plausible deniability, any proximity to OEM software increases liability if things go wrong.

Nintendo doesn't care. There's been proprietary Nintendo SDK code in libogc (open source library for making GameCube homebrew) for years. And more recently the various decompilation process have made recreations of linked code from the SDK that compile match byte for byte. In practice the legal risk of being sued into oblivion for this is not there. If anything there would be a DMCA takedown / cease and desist.

Right, but they are one of the biggest DMCA abusers. They killed many fan projects. They killed game renting in Japan as a concept. They killed Yuzu (a Switch emulator). And they could change their mind at any time.

For the record Yuzu included code for circumventing Nintendo's DRM they had on game carts. It violated the DMCA.

there isn't ?? I sorta thought we figured all this out decades ago when SMB and DeCSS were being reversed? I think dosemu or something as well ?

I seem to recall DeCSS being the 'hot button' as it was RE'd in a 'non clean' way, the code released, and then a 'clean room' RE could be made from the 'public' info ??

edit: actually, at the time I think there was German law allowing RE for 'interoperablity' or some such. But that was a long time ago so my memory might be off.

The background level of software copyright legal actions is significant enough. If plane attacks happened that much then it would give us solid evidence of TSA effectiveness even if they never caught anyone directly.

Dylan16807 3 hours ago | parent

When you say "case" does that mean you're rejecting the evidence of Phoenix technologies not getting sued along with all the other BIOS clones?

15155 2 hours ago | parent

Absence of evidence isn't evidence of absence. "Not getting sued" doesn't validate a legal theory - legal theories are validated in court where they become case law. Until then, they are plainly speculative.

This "clean room RE" fabrication is also not something so obviously compelling that nobody would ever attempt to challenge it - it's just that nobody has cared to put dollars behind it. IP provenance cases are enormously difficult to prove and are almost always settled ahead of trial. This concept is software engineer folklore more than anything.

Dylan16807 30 minutes ago | parent

Saying you won't believe it's effective at all until someone sues and loses isn't the most compelling argument. If nobody sues then yes that is some evidence of effectiveness. It's not an absence of evidence, you're misusing that line.

I think this comment is missing the forest for the trees. Obviously, ephemeral interaction is going to happen.

The author’s blogpost is sloppy and has some signs of being AI written. This kind of bleeds into the main point I’m going to make.

Asahi Linux folks are clearly more conservative and erring on the side of caution, so, this means that the glibness with which the author is treating any of this is probably sufficient cause to refuse his entries. It is unclear if LLMs should be considered a toxic waste dump in terms of trying to maintain a clean room. We have not established a standard. It is clear the author doesn’t think this is a big deal, so that’s one conflict. The other conflict is that it is not clear what their exact interactions with Apple Silicon folks is and their glibness of it doesn’t clarify anything.

If you take a group that is trying to be very careful about the potential legal landmines a still nascent technology has and you get someone that espouses a general glibness about those concerns wanting to merge code…why on earth would you expect that group to accept them as a contributor?

This is not to say this isn’t really cool and a neat use of LLMs, but it is totally understandable why Asahi Linux won’t accept the fruits of this kind of development. If it turns out that Apple can identify its non-OSS code in this, it’ll be a mess.

I wouldn't expect "flawless" support for those chips in the next decade, even with AI. The earliest-supported Asahi chips still have missing power management and dark silicon.

The only way to get flawless Linux support is to buy hardware from an OEM that supports Linux well.

"We don't want to take on the risk of working with a former Apple employee, who could potentially leak trade secrets and expose us to unwanted liability" is a very different statement than asserting that they were banned for deception.

Clearing those up is an entirely different matter than saying anything about whether former employees should be allowed to contribute to the project.

To the developer: it doesnt matter whatever you can upstream it or not. Just share the code and documentation of how this process can be reproduced.

For the kernel driver it's literally just: run the hypervisor, wait for the kick, save the UAT state, replay the whole thing, make sure the output pages change, then just follow the pointer to initdata until you've built the whole tree from scratch. LLM handles the rest.

Thanks for the post and answering here, but for someone to follow in your steps there really need to be more information: how did you handle physical hardware? Did it got stuck / frozen / whatever? How did you managed reset / etc? What is your actual step-by-step process other then just telling codex / claude code "do X"? What else had to be solved along the way?

I just think one good part of Marcan's work is that they streamed a lot of their workflow with all kind of problems occured along the way and you could see how to solve them.

And please so not let anti-llm crowd discourage you. People like me who want to use good hardware and already choose to pay for Apple one just need drivers that work good and feature complete - code purity and "quality" is secondary.

I detail most of the development process in part 1:

Contributor policies that ban LLM use wholesale. Not contributor policies in general.

It's okay to have policies against shitty code, blatant copyright violations or being an ass.

It's not okay to ban tool use when a person is honest about it. The only thing you can achieve with a ban is that people will learn to lie about it and conceal it better.

bigyabai 7 hours ago | parent

It's not my policy, and I don't personally agree with many/most of them.

But they do objectively exist in many desktop Linux projects. If you are the sort of person that sees software as "dead in the water" from AI prohibition, desktop Linux will feel like a mausoleum compared to macOS or Windows.

Dear fellow humans from "Hacker News". Hacking a driver that in itself documentation to black box Apple hardware is not any different from hacking $10 4G LTE modem.

Fact that a person who was not previously driver developer can achieve this in a few weeks is pure wonder. No matter what tools are used.

Leave legal questions to Linux Foundation laywers or whoever is responsible to accept or not accept the patches.

If Apple actually wanted to prevent any of this from happening they can just lock bootloader. They not just gonna do it now because someone used fancy text generator to make working GPU driver.

Attacking a person who spent their personal time and money on making walled garden black box hardware more usable, more privacy friendly and further away from landfill is a crime against the future of humanity.
