Re: GPL vs non-GPL device drivers
You are trying to cram this in a simple yes or no box, and it just doesn't
fit. There are questions nobody knows the answers to (such as what rights
you need to distribute a derivative work or whether compiling code makes a
translation).
Thanks, all for the discussion. I certainly learnt a lot. I definitely
expected to be flamed and roasted for posting my original message, and
was not disappointed :)
I do not possess all the knowledge ("legal" and technical) that people
who have contributed to this discussion possess. However I will still
comment from a user's perspective, which was my original point.
Many companies in the embedded field still mistakenly feel (or felt
until a while ago) that Linux was not right for them. That they would
have to open source their code, that they would not get adequate
support, and that Linux was too big and heavy to perform well in an
embedded platform. People like me who were Linux Desktop junkies were
actually trying to convince companies of the opposite.
Now the popularity of Linux is exploding in the embedded space. Nobody
talks of VxWorks and OSE anymore. It is all Linux. Perhaps it would be
a worthwhile experiment to study this surge in popularity. I am not an
expert, but perhaps the reason is "it works so goddamn well and has a
wealth of third party FREE software". Sure its a bit of work to make
it work on our platform and we don't have to Enea or Windriver to
write our gripes to. But it definitely is worth it.
Now it would also be worthwhile to contemplate what EXPORT_SYMBOL_GPL
does to this popularity. I don't know. I am just giving you my
opinion. The moment companies learn of something like this, alarm
bells start to go off. This is not rational. I personally have nothing
against open-sourcing all software. *But*, this is not how companies
think.
Let's think about why Linux became so popular and strive towards
keeping it that way instead of resorting to innovative ways of just
confusing a lot of people.
Having said this, I am committed to contribute back to the Linux
community in any way I can, not withstanding my present employer. Keep
up the good work guys!

Re: GPL vs non-GPL device drivers
It's written in black and white, in the license. Please point me to where it says I cannot load proprietary modules in the Kernel. Apart from that, Greg KH has made his opinion clear, and you have said you understand and don't debate that he holds this opinion, and his code is what you said you were linking to (the sysfs/class stuff), so why do you keep saying that "it is not clear". I know his opinion. I don't debate his opinion. It is his code. I choose not to use his code because of the license issue. Do you think that, somehow, Linus' opinion trumps Greg KH's opinion on his own code? No, just that the trend is disturbing. If enough Kernel Developers choose to write their Software in a way that prevents others from using it freely, then that is troubling.

Greg KH's statement was pretty black-and-white, and there are a lot of comments in this stream, from name-brand developers, that are in line with them. They're the best answer you can hope for on this question. The question you're asking is an issue of interpretation, which only a court can answer. Do you want them to modify the license to make this particular issue clearer? Or do you just want a statement from Linus? Which statement are you talking about? First of all it is not clear to me if proprietary modules need to be GPL or not. If they do, I guess I have nothing to say. If that is the way developers want it, so be it. Assuming these need not be GPL, I have a problem with EXPORT_SYMBOL_GPL and the general trend in the direction of making proprietary drivers harder on companies. Our drivers use basic interfaces in the kernel like open, read, write, ioctl, semaphores, interrupts, timers etc. This is functionality we would expect from any operating system. We used devfs before and had no problems there. Greg KH has gone and made the basic sysfs interface, which any generic driver could use as EXPORT_SYMBOL_GPL. I don't really care, I just don't use sysfs. The point is that old functionality is being ripped off and new ones introduced, and their interfaces are not open anymore. Hence there will be a point where non-GPLed drivers simply cannot be loaded. So why beat about the bush? Just make it illegal to load proprietary drivers, or remove EXPORT_SYMBOL_GPL. vj. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

If the Embedded developers don't contribute changes back, it doesn't hurt us any if they go away and start paying $$$ to VxWorks instead of using Linux for free. Contrawise, if Embedded developers do contribute their device driver changes back to the kernel, they will be fine.

It could be crap code, but it will fulfill the requirements of the the GPL. Others in the community can make the decision about whether they want to clean up the code and get it mainlined, or it ignore it if it truly is a one-off driver. All you have to do is make the driver available. And if you don't, why do you think that it is at all a credible threat, or that we should shed even one tear, if you go away and use some other OS for your embedded product? It's not like in the case of VxWorks where you get to say, "Do X or we take away a million dollars worth of business."

But that requires that you be a good community member. If in contrast you find that it's cheaper to pay $$$ to some embedded OS company, please feel free to do this.

I think you have a bit of a misunderstanding... Linux is not royalty free. Just the royalty is not in the form of cash, but in the form of having to give your improvements back to the open source world. Sure. But this is not legally binding.

Re: GPL vs non-GPL device drivers
You don't get it do you. Our source code is meaningless to the Open Source community at large. It is only useful to our tiny set of competitors that have nothing to do with Linux. The Embedded space is very specific. We are only _using_ Linux. Just as we could have used VxWorks or OSE. Using our source code would not benefit anybody but our competitors.

Re: GPL vs non-GPL device drivers
No its not. It wasn't common knowledge 3 years ago when we chose Linux as an embedded platform. If it indeed is common knowledge that loadable modules in Linux have to be open-source then it is very probable that we wouldn't have chosen Linux as the platform of choice. If this indeed is the case and is common knowledge, then I predict that Linux will soon drop in popularity as the OS of choice in embedded systems.

GPL vs non-GPL device drivers
This is in reference to the following thread: http://lkml.org/lkml/2006/12/14/63 I am not sure if this is ever addressed in LKML, but linux is _very_ popular in the embedded space. We (an embedded vendor) chose Linux 3 years back because of its lack of royalty model, robustness and availability of infinite number of open-source tools. We recently decided to move to Linux 2.6 for our next product, mainly because Linux has worked so well for us in the past, and we would like to move up to keep up with the latest and greatest. However in moving to 2.6, we noticed a number of alarming things. Porting drivers over from devfs to udev, though easy raised a number of alarming issues. Driver's no longer could dynamically allocate their MAJOR/MINOR numbers. Doing so would mean they would have to use sysfs. However it seems that sysfs (and the class_ interface) is only available to GPL modules. This is very concerning. The drivers which we have written over the last three years are suddenly under threat. We don't mind statically assigning MAJOR/MINOR numbers to our drivers. We can do this and modify our user space applications too. However we have a worrying trend here.

Re: GPL vs non-GPL device drivers
You don't get it do you. Our source code is meaningless to the Open Source community at large. It is only useful to our tiny set of competitors that have nothing to do with Linux. The Embedded space is very specific. We are only _using_ Linux. Just as we could have used VxWorks or OSE. Using our source code would not benefit anybody but our competitors.
