Ford Dumping Windows For QNX In New Vehicles

innocent_white_lamb writes "Ford has announced that their in-vehicle technology called Sync will be based on Blackberry's QNX operating system and will no longer use Microsoft Windows. My own 2013 Ford Escape has the Windows-based Sync system. I wonder if they will issue an update to change it to QNX." Anonymous sources inside Ford cited reliability problems with Windows and lower licensing costs for the switch to the classic realtime OS.

      Ford seems to have their priorities seriously screwed up if that is the case. Shouldn't they make sure the powertrain works before working on the infotainment system.

      Stopping and stopping a car a lot decreases the mileage. That's why city mileage is always worse. With Windows your car needs to stop and reboot at bluescreens. With QNX you won't have that problem.

      Linux is an RTOS as long as you select the proper configuration.

      No, it's not. They've done some very clever things to reduce Linux response latency, but it's not deterministic, and hence not (hard) real-time. I add the word "hard" only because some people have mistakenly conflated real-time with responsive, leading to the oxymoronic term "soft real-time". Also, even with the clever mods Linux's latency is much longer than many RTOS's.

      I love embedded Linux, but if you need an RTOS, it's not the right tool.

      BTW, why would Android even need to be an RTOS? What purpose would it serve?

      And for entertainment based systems, you don't really need RTOS - just a reasonably fast system.

      Yes. I only mentioned RTOS's to counter the common notion that there can be a universal OS for embedded work.

      RTOS implies determinism, the ability to execute things in a timely manner. That means prioritizing interrupts and allowing high priority threads and processes to preempt the kernel and other core OS processes or threads. Many people mistake real time for processing something as it arrives into the computer e.g. a near latency free video image on screen from a camera or reading a stream of GPS coords from a serial port. Lets go with the camera example. While this sounds like real time, there is no software or hardware that guarantees that the image software and camera driver will always deliver an image to the screen in a guaranteed and timely manner. For example if you start the camera application and you play a video game, does the "realtime" video application retain its low latency? Or will it stutter as its process fights for CPU time with the video game process as the OS sees fit? In a true RTOS, the video software AND driver TELLS the OS their priority and the OS obeys. They can be assigned a high priority so any other software will have to wait until there is spare CPU time.

      Linux has two routes to achieve this:
      CONFIG_PREEMPT_RT
      Patches to the Linux kernel which removed the various locks in the kernel (aka big kernel lock) which allows a process to be prioritized over the kernel itself. IRQ's are also prioritized. You can run various processes and assign them a priority.

      Xenomai
      Xenomai is a dual kernel approach where a vanilla Linux kernel is patched with Xenomai. It creates a separate kernel that allows its processes to preempt the Linux kernel and takes over handling interrupts through the I-pipe. This means all interrupts are handled by the Xenomai kernel and if an interrupt is destined for the Linux kernel, Xenomai passes them as a virtual interrupt. Xenomai also features its own HAL allowing hardware to be dedicated to Xenomai processes via RT drivers. You can also do things like dedicate a processor core to a specific task to guarantee there is ample CPU time. And Xenomai has a neat little trick, its kernel is a nucleus which can run various "skins" which are API's; e.g. you can use RT code using Native, POSIX, uITRON, VxWorks and a few other RT API's.

      YMMV but both solutions have tradeoffs. There is a paper published (https://www.osadl.org/fileadmin/dam/rtlws/12/Brown.pdf) which compares the two popular Linux RT solutions. Preempt_rt is easier to implement as it is part of the mainline kernel, you only need to include a few headers and some gobals to define the process priority. But in tests it shows higher timing jitter than Xenomai. If you want maximum performance, then you need to look into Xenomai which requires a bit more setup, patching and using the various API's and RT hardware drivers.

      BTW, Windows also has RT dual kernel systems. So yes even windows can be an RTOS. Look up Ardence RTX and INtime.

    For all of us who feel only the deepest love and affection for the way computers have enhanced our lives, read on. At a recent computer expo (COMDEX), Bill Gates reportedly compared the computer industry with the auto industry and stated, "If GM had kept up with technology like the computer industry has, we would all be driving $25.00 cars that got 1,000 miles to the gallon."

    In response to Bill's comments, General Motors issued a press release stating: If GM had developed technology like Microsoft, we would all be driving cars with the following characteristics:

    1. For no reason whatsoever, your car would crash twice a day.

    2. Every time they repainted the lines in the road, you would have to buy a new car.

    3. Occasionally your car would die on the freeway for no reason. You would have to pull to the side of the road, close all of the windows, shut off the car, restart it, and reopen the windows before you could continue.

    For some reason you would simply accept this.

    4. Occasionally, executing a maneuver such as a left turn would cause your car to shut down and refuse to restart, in which case you would have to reinstall the engine.

    5. Macintosh would make a car that was powered by the sun, was reliable, five times as fast and twice as easy to drive - but would run on only five percent of the roads.

    6. The oil, water temperature, and alternator warning lights would all be replaced by a single "This Car Has Performed An Illegal Operation" warning light.

    7. The airbag system would ask "Are you sure?" before deploying.

    8. Occasionally, for no reason whatsoever, your car would lock you out and refuse to let you in until you simultaneously lifted the door handle, turned the key and grabbed hold of the radio antenna.

    9. Every time a new car was introduced car buyers would have to learn how to drive all over again because none of the controls would operate in the same manner as the old car.

  10. Sync was so bad.... by EmperorOfCanada · · Score: 4, Interesting

    Sync was so bad that I wouldn't buy a Ford. I rented a handful of 2013 model Fords with the Sync system. I had an iPhone 3GS and an iPhone 4. The stupid Sync system was a huge battle. Syncing just wasn't a clean process. It did work but smooth as silk is not how I would describe it. But then it got worse. It asked if I would like to set up the emergency something. I presume this was an automated 911 call if I crashed. Well actually no I don't want the computer calling the police; I'll make phone calls of that nature thank you very much. And in today's world it is unlikely that if I were to crash that there aren't 200 people with cellphones that will call anyway. But lastly the system was so crappy I doubt that it would call 911 but would call 912 or 999 thinking that we were in the UK.

    But you are probably thinking no big deal opt out and you are fine. But nope after opting out, every time the stupid car started a woman's voice would blah blah about the emergency system not being activated. I looked in the manual and found no solution, so I went on the net and found no solution. So there is no way on earth that I would buy a Ford. Plus my sister had minor damage (but enough to partially disable the car) in a recent model fusion hybrid that took nearly 5 months to get the parts in. So she was out a near new car for 5 months; the whole point of buying a new car vs nursing a 10 year old car along is that the new car saves you the stress of breakdowns and any maintenance issues that cost anything or at least are hard.

    But now Ford is leaving the abusive relationship they no doubt enjoyed with Microsoft and now they are getting into bed with the $2 whore that they found in a Ottawa brothel. I couldn't think of a technology company (after leaving microsoft) that I would rather partner with less than Blackberry. I fought with their stupid Playbook tablet and I have watched people fight with their stupid new QNX phones. I know people who are long term BB customers (often via work) who deeply resent the latest models. So why would you pick a company that is on the rocks and that people respect less than the aforementioned $2 whore?

    But oddly enough the main reason that I think that QNX is a complete bowl of stupid is that I have known exactly one programmer who loved QNX and he was a useless tool. Actually worse than a useless tool; he was one of those developers that management thinks is a rocket surgeon but all he does is make things way worse. So if he tells you to cut the blue wire, not only should you not cut the blue wire but you should assume that cutting any wires is probably the exact wrong thing to do. So keep in mind that this tool probably thinks that QNX in a Ford is a cool idea.
