OpenBSD 7.9 was already on the 6.18.y longterm support version for the drm(4) drivers, Jonathan Gray (jsg@) completed the update back in March, sponsored by the OpenBSD Foundation.

I just wanted to highlight Jonathan's continued efforts backporting updates in my usual "HYPE" post series for the upcoming OpenBSD 8.0 release.

(I'm the author of the mastodon post that was shared.)

Note that OpenBSD is on 7.9 now and all releases are possible breaking changes.

They release every six month and increment by 0.1. And after 0.9 they rollover to the next whole number.

So don’t think of version “8.0” as a major release per se, since OpenBSD is a fixed schedule release - not a Major.Minor release.

Are these two statements a contradiction?

Thinking out loud, maybe the spirit of your comment is, “Every OpenBSD release is possibly a breaking change; the version numbers don’t mean anything.” Otherwise, I don’t see how it’s relevant to mention the current release ends in .9, then explain how the next version is constructed.

Please help me understand. I truly have no sense of how things work in OpenBSD land. The spirit of my comment here is entirely in good faith, just trying to learn.

What they meant is that, in terms of scale, the jump from 7.8 to 7.9 is more or less the same as the jump from 7.9 to 8.0

This is similar to Linux kernel versioning

I think they mean in addition to all releases possibly having breaking changes, the developers did not pick 8.0 instead of 7.10 because they thought this is a significant milestone, but instead because they always roll from N.9 to (N+1).0.

OpenBSD predates popular semantic versioning conventions by a few years.

I think MS-DOS already used in the 80s what you call "semantic" versioning. (Most probably even earlier examples, this is just the first thing that came to mind.)

No, MS-DOS followed a simple major.minor scheme, with major bumps signifying project milestones or marketing reasons.

Semantic versioning is not what I call it, it’s a formal specification: https://semver.org/

nta but yes your spirit reading is correct. They're saying OpenBSD treats the version number as an integer, and every update adds .1. So 7.8 -> 7.9 -> 8.0, regardless of how significant or breaking the changes are.

How does GPL code get ported to BSD?

Most of the common drm code and kernel gpu drivers are already MIT/X licensed for historical reasons, same goes for the Mesa GL and Xorg components.

https://github.com/openbsd/src/tree/master/sys/dev/pci/drm

Huh; I would have thought that importing MIT code into a GPL codebase (like the Linux kernel) essentially “beats out” the original MIT-licensing and instead creates an GPL-licensed fork of said code; thus making such forked code ineligible for re-import into an MIT/BSD-licensed project like the OpenBSD kernel (unless that project wants to be infected by the component’s licensing and become GPL-licensed in turn.)

Are you saying instead that the DRM drivers in the Linux kernel (the in-tree parts, I mean, not the firmware blobs) exist as an island of MIT-licensed code inside the otherwise GPL-licensed codebase?

Or are these parts of the Linux kernel not even technically in-tree, but rather developed in a separate canonical repo and frequently synchronized into the kernel as a vendored dependency? That’s the only way I can see this working; but it’s unclear to me why this state of things would have been maintained for any length of time when the Linux kernel was the only consumer…

Each file has their own license, and they are on the same repo.

The GPL is (in)famously viral. You can't base something on a GPLed codebase and say that your thing isn't covered by the GPL. The GPL is specifically designed to forbid that specific thing.

You can take BSD-licensed code and package it into a GPL bundle, which is what the kernel is doing. You can also extract the BSD-licensed code without the GPL-licensed code and it will be fine.

It depends on how closely the code is coupled to the rest of the project. Traditionally, sharing an address space carried the GPL taint. There's nuance to it, of course, but the question was never really settled, and nowadays people just ignore licenses.

OpenBSD has a strict "no GPL" policy. It does not incorporate GPL code in the kernel, and it has slowly weeded out GPL code from userland. This is one reason why it builds with Clang instead of GCC.

If Linux DRM weren't licensed under more permissive terms, OpenBSD simply wouldn't permit its inclusion.

> Traditionally, sharing an address space carried the GPL taint.

Clearly two different files don't share the same address space. So no problem.

When you link GPL code with your proprietary code into a binary (shared address space), and distribute the binary to people, those people are entitled to your proprietary source code.

When I compile my GPL code with a copy of somebody else's MIT code into a binary (shared address space), other people's copy of that MIT code is still MIT licensed.

No, you don't get to change the license on someone else's code just because you import it into your project.

That‘s a common misunderstanding how licenses work on HN. Often even worse: "MIT allows relicensing" (no it doesn‘t, and sub-licensing is something different).

Behold the full set of licenses and copyright notices that apply to the Linux kernel, scanned with FOSSology[1] and ScanCode[2], and curated by licensing professionals: https://raw.githubusercontent.com/Open-Source-Compliance/pac...

Yes, you need to supply all of those if you distribute the Linux kernel in binary form. No, most companies don‘t do that in practice. Yes, they are in breach of all those licenses. Yes, next kernel release there will be changes.

I‘ve long been procrastinating on writing a blog post about exactly that.

TIL, thanks! I wondered if that was the case, but couldn't find a license while clicking around in the code on my phone.

I wonder if it's downloaded after installation, like nonfree codecs in many Linux distros

Yes. The firmware blobs get downloaded at the end of the install via `fw_update`.

Specifically in this script https://github.com/openbsd/src/blob/master/distrib/miniroot/...

Just look for `fw_update`

Genuine question: if this is only a catch up game, then why not just use the original in the first place?

So, AT&T UNIX System V it is then.

I think the OP was asking the honest question: why not use Linux if the graphics stack is from Linux anyways. It's a fair question and I ask that myself.

Presumably because the other features of OpenBSD bring in some benefits to OpenBSD fans. Also you can always develop on your OpenBSD desktop (with the Linux shim) and then deploy to the server without the Linux shim.

I know, but felt that it was the kind of answer one should get when discussing UNIX systems.

Many of us that enjoy UNIX, regardless of its flaws[0], and do not appreciate a GNU/Linux monoculture, similar to having Google taking over the Web with Chrome OS forks.

[0] - Remember that its creators moved on from UNIX and C, creating other systems they saw as improvements on their creation.

I got your point about the monoculture, and I agree with you. Being different is not something bad.

My question was more nuanced though. It seems to me that in the past 10 years or so, openbsd didn’t invent very much. Of course that I agree that there are some punctual things where openbsd was first but that’s not the case lately. So it’s mostly a catchup game with linux features and compatibility needs for running linux software. If you open now the HN front page you will see one story about openbsd importing linux drivers and another story on openbsd struggles to support wine - and basically how wine developers don’t care too much about that.

Hence my question, if most of the effort is put to catch up with linux features, is it even worth anymore? If I want to use linux from 5 years ago, I could just do that. Putting so much effort and time into developing a linux feature clone just in case linux becomes evil, also doesn’t make sense, because you can fork when you see this. Licensing wise even less, I think there’s now a mixture on both sides.

So please take it as a genuine question, not as criticism or anything.

Yes, because an OS is much more than drivers, the culture among its users and developers is quite relevant, and OpenBSD users certainly don't want to deal with many Linuxisms like systemd for example, or rather favour pkg approach to software delivery, that is why they are on a BSD in first place.

Just like others might favour Illumos, Aix, z/UNIX, macOS or whatever take on UNIX evolution.

Linux has effectively been taken over by big business. OpenBSD is still relatively independent.

There are parts of me that don't want to say this but will LLMs actually help Linux and smaller OSes by accelerating reverse engineering hardware that doesn't have open/good enough specs? Will we reach a point where hibernate works reliably on Linux? Weird hardware can be used well by FreeBSD?

I'm very happy and lucky to have to a modern laptop where everything just works including S3 hibernation in FreeBSD.

MSI Modern 15

This has nothing to do with LLMs. The *BSDs have been porting Linux video drivers for years. This is just the status quo of how video drivers on OpenBSD work.

I see quite a lot of announcements of compatibility and porting efforts -you would never know if someone used an LLM to help, but I would bet money it is being done without admitting it.

Just because you don't know how to do it doesn't mean they don't. As I said, the same people have been doing this for years, long before LLMs. They need to re-sync with upstream periodically so that's why you see announcements of new stuff.

What makes you say I don't know how to do it?

Also, people who have been doing something for years are exactly the people who benefit the most from having pointless toil removed from the workflows.

Attitudes like yours are exactly why we won't know what level of AI assistance is used. People won't admit it because there is a lot of downside to doing so - especially in communities like this.

Because you assumed they would direct an LLM to do it and lie about it. Seems like projection to me.

Your logic is ridiculous - I wouldn't post publicly like this if I was projecting.

It is just an obvious fact that when there are hostile swarms of people like you, that it is prudent to not disclose when you used an llm to unblock yourself.

I was being very neutral about this obvious fact and you became irrationally hostile.

"I would bet money they used LLMs and lied about it" (paraphrasing) isn't neutral.

I didn't say or intend to say 'they' did it. I said I bet it is being done in general. Maybe that is the core misunderstanding here.

I fully believe the BSD people didn't use it - I just think in general you wouldn't know which projects are doing it and which aren't.

In fact, if you dig into these projects, they have llm disclosures for misc debugging and other things.

You tell me I'm part of a swarm of people like me, but we haven't met, and I don't think you have enough information to know what a person like me is.

On the other hand my life experience is often that people who accuse others of doing activities in secret, and being dishonest about it, that is often, but I will give you not always, indicative of where their own head is at.

I think you misunderstood what I said or I didn't say it clearly. I was speaking in general terms of trends across our industry, not this specific project.
