Explaining The Symbiosis Between QNX RtP & Linux

Thanks to Mike Bouma who put together a paper with the help from a number of the Phoenix project members which gives more information regarding what's going on with QNX and why it matters.

Explaining the Symbiosis between QNX RtP and Linux

The Linux community and its open source approach has huge potential and helps us greatly to realize our goal to make the QNX Realtime Platform a superior general purpose desktop and developer operating system. QNX RtP is fully compliant with the latest POSIX standards. This, together with a X11 compatibility layer for the Photon MicroGUI, means most Linux/Unix applications only need simple recompiles and modifications to be ported to this new platform. So whatever Linux/Unix gains the OS will gain as well! Currently QNXStart.com already has a nice software library and Tucows is busy building one. The freely available award winning Voyager browser is excellent and plug-ins like Flash 4 and RealPlayer 7 are already available. Also Amiga`s Digital Environment is being developed to support the QNX RtP and will not only provide us with a common binary identical application layer for Linux but most other operating systems as well. The Tao Group (Amiga`s OS partner) already provided QSSL with a wonderfully small and efficient Java VM implementation for its predecessor QNX4. In addition QSSL and IBM are working together on a real-time technology for Java applications under the QNX Realtime Platform.

Giving source code away freely for everyone to use does not make sense for everybody. Especially commercial companies would not be motivated to spend years on OS development and make the fruits of their work freely available for rival companies. With QSSL being the owner of this OS and offering all the relevant source code to developers, developers can invest their resources while still being protected from competitors. So QSSL offers prime advantages of both the open-source and commercial worlds! !

One month ago the pre-release developer version of the QNX Realtime Platform was freely released for public download freely for non-commercial use. Since its launch more than 400,000 downloads at http://get.qnx.com followed, while bringing even Tucow's servers to their knees. Additionally, QSSL has set up a developer's support network with weekly articles by QNX experts giving their insights on programming under the QNX Realtime Platform. There are very ambitious projects for this new OS and many exciting new developments will be announced when the time is right.

But what makes QNX RtP so special, you may ask?

QNX RtP is an excellent realtime operating system, which means that all programs are smoothly given CPU time (according to the priority they are given in the Scheduler). This gives developers or users the option to set high priorities for certain tasks, so that for instance a multimedia player will be quaranteed to respond and function optimally in any given situation. The stability and realtime abilities of QSSL`s OSs resulted in them being used heavily in fault intolerant and response critical systems, for instance nuclear reactors, medical equipment, space craft, traffic control systems , etc.

Within the embedded market, a small memory footprint and optimal efficiency are very important issues. QNX RtP is based on the modern and optimised QNX Neutrino microkernel. OS modules such as file systems, TCP/IP and even drivers run as normal memory protected user processes, allowing them to be plugged in and removed at any time without a reboot. This allows QNX RtP to be scaled down or up very easily for use in compact Internet Appliances as well as in full blown multi-processor servers (3Com`s Audrey IA has just been released and uses the QNX RtP at its core.). It also eliminates the need for special kernel APIs and debuggers, greatly simplifying driver development and debugging.

Although I could continue for hours telling you endlessly about other benefits I will end this by highlighting one other great feature which impressed most developers involved instantly, when we started our relationship with QSSL a couple of years ago. It truly offers superior flexible and transparent networking abilities. As an example of its flexibility; you could have a game running on one computer in a network, while it is being controlled by a joystick on another computer within the network, and its graphical output being displayed on a monitor of another machine again! One demonstration was of Doom running on two connected machines to begin with; it was running on one machine, then the window it was running in was dragged onto the display of the second machine, then it was partially dragged back, so the game was running synchronic and seamlessly with half a window on each screen!

Something wonderful is coming. Do you want to join the exciting battle to change computing and topple the choking monopolies within the industry? :)

Sincerely, Mike Bouma.

Sure if you wanna play a dvd or browse the web its great to toy around with for that stuff, but you can browse the web just as well in linux/fbsd/windows. With no virtual memory disk swapping, it makes it easy for them to make it more realtime, and harder for people to write complex programs (ala photoshop). "Welcome to early macos." I've used both QNX4 and neutrino now for over a year. I've written some drivers for it, and work for a company that has a product based on it. It's not as cool as they make it sound.

    Well, we'll see. Be's position on the "desktop or not?" matter is more or less officially schizophrenic (I know both the Be engineers and marketers would take offense at that characterization, but it seems true enough in practice). At this point, QNX is sending mildly mixed signals that aren't unfamiliar: engineers being involved out of a sense of geek love, but a corporate stance which appears to have only marginal interest in the matter.

    In the long term, who's more committed? Maybe it is QNX. Again, the signals from Be are schizophrenic; while their developer support for the desktop is less enthusiastic than QSSL's, you can't walk into Best Buy and buy a boxed RtP set with a printed manual. Despite Be's stated future direction, BeOS is their only currently available product, and QSSL hasn't (to my knowledge) announced any plans for a retail equivalent to BeOS 5 Pro--being in the retail channel is a measurable commitment that hasn't been made with Neutrino yet. (And it's one that could suggest Be is, characteristically, hedging their bets for next year's Annual Focus Shift. In 2001, Be will be repositioned as... oh, I'm sure anything I say won't be as humorous as whatever their marketing gurus come up with, right?)

    My more serious concern (about both platforms) is this. If the OS's growth and direction are controlled by a for-profit company, and they have made business choices that do not depend in any substantial way on the OS succeeding on the desktop, there's only so much external "community" forces can do to force that success. I'm sure QNX RtP will gain a cult following... but it remains to be seen whether that'll be enough to break out of the Geek Toy Ghetto that BeOS is in, i.e., a product everyone likes but few people actually bother running. QNX has the advantage of running Linux apps, granted, but a cynic might say that just gives it a little OS/2 mixed in with its touch of Be.

    Bizarrely enough, the only new-yet-closed OS company I see really agitating in the way I think will be needed for success is Bill McEwen's new new new new new no we really mean new this time Amiga. Amy the Squirrel may yet have the last laugh.

  5. No, it's another BeIA by Watts+Martin · · Score: 3

    A comment from "(Mike)(duh)" further on down claims the difference between BeOS and Neutrino is that the latter is attracting developers and BeOS isn't. This is highly misleading. But, I'm not sure Ars-Fartsica is 100% on target, either.

    BeOS did have a lot of announced commercial support this time last year--from companies that to date still have shown no interest in Linux. While there are some quantifiable advantages BeOS has in media performance over Linux (and, I would submit, over QNX as well), the difference wasn't technology--nor was it that the companies didn't "trust" open source, as some BeOS cheerleaders claim. It's that Be had strong developer support. These companies wanted somebody there able to offer immediate, detailed support and corporate evangelism. Linux can come close to this sometimes, but it definitionally can't match it, simply because there is no "Linux Company" that gives you access to nearly all the great developers. "It's open, you can make the changes yourself" isn't as good an answer as "we've tracked down that bug and fixed it for you," if (and it's a big if) there's a group able and willing to do the latter. This marketplace reality is why companies target specific Linux distributions--it's because Red Hat, SuSE, and Caldera are trying to do for Linux what Be was doing for BeOS. A company may feel comfortable porting to "Red Hat Linux" because they're not doing the port alone, they're doing it with Red Hat's technical--and possibly even financial--support.

    So what happened to BeOS? Be stopped providing that support for the desktop, shifting nearly all their DTS resources to BeIA.

    I've looked at QNX RtP, and sure, it's pretty neat. But it is in the same position on the deskop that BeOS is--the desktop incarnation of a closed operating system whose company intends to focus their resources on the "appliance" market.

    Look at the business and marketing FAQs on get.qnx.com. Do you see anything about their plans for the alternative desktop market? "It's uniquely positioned to become the premier platform for embedded devices." When they're comparing it to Linux, they're talking about its advantages to embedded systems developers:

    QNX provides OEMs with a large suite of applications and OS components that are thoroughly tested and highly optimized for embedded use. No re-engineering required. This gives developers a head start: Instead of losing time on low-level kernel issues (and spending money on OS maintenance teams), they can focus right away on creating unique features and applications for their embedded device.

    QNX RtP isn't intended to be a desktop OS contender: it's been released as a "self-hosted development environment" for RtP-based appliances, as well as a demonstration to potential partners of what the system can do.

    Just like BeOS is for BeIA now. Rah, rah, focus shift.

    QNX is a bunch of great guys, from what I can tell, but don't kid yourself, folks. This is not the next great alternative OS; no operating system is going to be without serious pushing from a corporate developer.

    Opening the source helps with developer mindshare, sure, but I'm not sure it'd help much; there'll be enough hackers porting Unix stuff over without it, and it's a rare profit-driven company that gives a fig about such issues--they just want to sell their products and/or services, and that requires a userbase. (If BeOS had a few million users, Corel would have been there porting already. Whether we'd want them there is another question, of course, but I digress.)

    In any case, the source isn't going to be completely open in either case; both companies see their kernels as their prized product. In practice, they could use a license like the Aladdin Ghostscript one (essentially, free for most use, but commercial redistribution requires a license), but let's not hold our breath.

    Releasing free software doesn't make sense for everyone. OK, but using free software that other people have released sure makes sense to them. It doesn't seem like much of a fair exchange as far as I can tell.

    I think Linux compatibility might make the QNX stockholders happy, for a while. But QNX should target to what they do well rather than trying to be a general-purpose OS. There's little value left for them in that market when so many competitors don't even want your money.

It's a massively scalable, multi-threaded, fault-tolerant, realtime OS designed for devices and computers of any type or size. QNX provides a unique network architecture where large full-service protocol stacks aren't required on each computer and devices plugged into the network are simply "discovered" automatically by other devices - all services and peripherals of the new device can then be used by any other device in the network. QNX is also the only self-hosted RTOS where the development environment and the runtime target environment are the same. And though we're not open source, we adopt an "open source" policy for hardware-specific drivers. This allows us to continually support the latest hardware advances, while still maintaining control of core technology. More importantly, it ensures QNX has a focused vision for the future.

    More recently, I had a brief fling with LynxOS 2 years ago; after several days of can't-get-it-to-install-even-with-tech-support-pho ne-calls, changing the NIC and video card 'cause LynxOS didn't like'em, and general difficulty using it, I went out and bought RedHat 5.0, and I'm never, ever going closed-source again unless forced. (BTW, the funny thing 'bout LynxOS was, all the primary development tools were GNU; gcc, gdb... Only the profiler and MetroX X server were proprietary. Now, tell me again why I paid $30K for this package?)

    Yes, I MAY be able to get superior real-time performance out of a closed-source OS (unproven IMHO); but my systems, like MOST of those out there, do NOT stretch the boundaries of achievable performance. I'm running P5-200MHz front-end systems using VMEbus; if I need more performance, (which I haven't yet and probably won't), I'll just slap in a faster CPU card. So far, I've had to hack the NIC code once to eliminate a funky media-autosense problem, and the VME driver to accommodate the VMIC VME implementation (the latter has since fixed by VMIC; great people, I HIGHLY recommend them, AND they support Linux on their iron!); I could NOT have done this with LynxOS or QNX, and MY experience says there's every chance I would have needed to do so.

    It's not ideology that moves me to say this, and not cheapness (the OS cost isn't an issue in my systems); it's Linux' better flexibility, equal or better reliability and hardware compatibility, and that source accessibility that make it my primary choice for an OS.

    As a practical matter of getting my job done, Open Source wins for me. Period.

QNX will always have its niche guaranteed and has been around for ages, it doesn't need to make its proof like BeOS does (an other comparison which makes me uneasy).

    Hold on a second there, before you flame me. I love linux and I run slackware. I also love FreeBSD. And I run OpenBSD on my laptop. But there is one thing I really don't like about Linux--the design of the kernel. I dont like the idea of recompiling the kernel for new drivers. QNX is truely modular. Companies can release binary-only drivers for QNX and they work. This does not work well with linux, because the kernel changes every second.

    You see, Linux started as a project to run on one computer. QNX RtP is designed by engineers who had a clear view of what they want it to be when it is done. It is well engineered. With linux, you have to change the kernel to add drivers! That is NOT the way it shold be done! This is not a problem with QNX.

    All this being said I still love OpenSource, and I like linux but hate the way drivers are implemented in it. I would trade a poorly designed opensource kernel for a smaller, more modular commercial one, as long as the rest of the OS is open source. With QNX, you dont need to hack the kernel itself, because it is very small.

    Modularity.

    Be has a solid OS, and just because its not Open Source doesn't mean it sucks and that Be should drop into the infernal abyss.

    Of course Be has a quality product - but part of the marketing of that product is a decision whether or not to open the source. Like it or lump it, The BeOS market and the linux market are basically the same - people who are willing to try an alternative OS - and most of the users in this market are using the openness of the source in their product decision.

    Be could have made that decision early on to capture mindshare - they didn't - and now they are toast. The bottom line is that you give users what they want. Even if the CEO doesn't think open source makes sense, you listen to users. If users want a free car wash and a commemorative plate with each OS install, thats what you give them.

    Linux is a decent OS, it has a few things to learn (Which is why I use BSD :), but the thing that bugs me most about Linux are the claims by its users that it can cure (insert "world hunger", "war", "disease", whatever else here.).

    Speaking as someone who has used FreeBSD for five years, I can tell you that most of the cool userland stuff to land on BSD in the past three years has come from the linux userbase. Gnome and KDE would not have ever come about if not for the linux craze.

    I really don't see what you guys are getting so excited about. What sets QNX apart from all the other commercial RTOSes out there? It's a commercial endeavour! Yes, you can download a demo disk. But you don't get full source and you're not allowed to use it for any real work. Sounds pretty much like VxWorks or any one of the dozens of other competitors to me. Call them, they'll send you a free demo too!

    Read the FAQ. Their opinions are stated in plain view:

    Q: Why doesn't QNX provide source to the kernel and other core OS modules?
    A: Because QNX developers don't need kernel source to extend the OS.

    Anyone who's ever done serious work in embedded systems know the kernel source is absolutely essential for debugging, not only the application but also the kernel. All OSes contain kernel bugs. They're a pain to find and fix without source, and those of us who've been there are not going back lightheartedly. You all know this, that's why we're embracing open source. How come so many of you are now eager to jump back into the dark hole that is proprietary software?

    For embedded work, there's ECOS already. It's Free Software and runs on a dozen different CPUs, with new ports coming all the time. If you want the 3D acceleration, anti-aliases graphics and macromedia player, you're probably not looking for embedded stuff in the first place.

What exactly do people not like about RtP? -That it isn't completely OS? If that's a sticking point, then it's likely to remain one, because RtP won't go completely OS. -That is doesn't yet have a huge feature set (drag and drop, DVD, etc?). Given that this is a pre-release verson, who expects those things? It's come very far in a short amount of time, and has some stuff that more mature OSs like Linux don't. I for one have downloaded RtP for desktop use, and it's fast, responsive, and has a decent amount of features for a pre-release version. The included development system is, IMO, fantastic, especially the documentation. I keep seeing comparisons to Be, which I don't think are completely off the mark, except for one major difference: QNX has a proven track record and is attracting developers. Be isn't.
