Linus: '2016 Will Be the Year of the ARM Laptop' ( 182

jones_supa writes: Linus Torvalds took the stage at LinuxCon Europe in Dublin, Ireland, and talked about a number of things, including security and the future for Linux on ARM hardware. There is nothing that will blow your mind, but there are a couple of interesting statements nonetheless. Chromebooks are slowly taking over the world, and a large number of those Chromebooks are powered by ARM processors. "I'm happy to see that ARM is making progress. One of these days, I will actually have a machine with ARM. They said it would be this year, but maybe it'll be next year. 2016 will be the year of the ARM laptop," said Linus excitedly. He also explained that one of the problems now is actually finding people to maintain Linux. It's not a glorious job, and it usually entails answering emails seven days a week. Finding someone with the proper set of skills and the time to do this job is difficult.

If you think users will "cut you a break" because its ARM? News Flash they don't know a CPU from a HDD, they WILL expect it to do every.single.thing. your average laptop in Walmart does? When it don't? Hello return desk.

            2.- Go look on your local CL under Chromebooks, News Flash they are already being dumped en masse because to steal a line from a former POTUS "Its the programs stupid!". People see a Chromebook, and again I cannot stress this enough users have no fucking clue what an OS is and all they know is "I use Google at home, it says it is from Google, so I can do everything I can do at home" and after a couple of weeks of finding out that is NOT the case? Hello Craigslist. I just looked on mine, they have a pile of 'em in the $70 range and most have been there awhile, know what that tells me? The users are treating them just as they treated those cheap tablets, they use it a few weeks, find it wanting, and get rid of it.

            3.-...Sigh, how hard is it to understand? YOU know what an OS is, know who don't? THE VAST MAJORITY OF CONSUMERS that is who! They aren't gonna know WTF an "Android" is because, and I bet my last fucking dollar damned near everyone of them will say "that is for cellphones" and is that a cellphone? Nope its a laptop and therefor should do what laptops should do which according to Joe and Jane is RUN WINDOWS PROGRAMS, when it don't? Hi return desk, I'd like to return this?

            4.-GPUs...Will these GPUs run all those Winhdows programs that Joe and Jane WILL expect it to run, because that IS what runs on the laptops at Walmart? No? Then nobody will have a single fuck to give, next!

            5.-Windows 10? Yeah that is why you are extra fucked as again Joe and Jane have not a single fuck to give about rumors of spying, data collection, all that shit means nothing, for fucks sake they blab their sex lives on FB! What they DO care about very much is Windows 10 LOOKS like Windows 7, and all their programs run on it just fine. Ya know what I do to Windows 8 PCs brought into the shop with users demanding I "fix it"? I slap in classic shell, voila! That'll be $50 and they hand it over with a big happy smile on their face because all they care about is the GUI and form factor and if its a laptop that LOOKS like Windows 7? Well they are just happy campers and Win 10? Looks like Windows 7.

            All of these points you are bringing up? Yeah its pretty damned obvious that you have NEVER worked retail or you would know that Joe user? He don't even know WTF those words even mean! An Operating System? CPU? GPU? What are those? If its a cellphone it should act like a cellphone, a laptop should act like a laptop, which means it should look and act like Windows.

        At least of you have an x86 Chromebook, you can always load Windows 10 on it if ChromeOS doesn't work out for you.

        Depends on the bootloader. Some just ship with coreboot and that's it - you can't boot Windows that way. Windows requires either BIOS or EFI to boot, and most Chromebooks ship with neither.

        Plus, chomebooks are a pain if you want to use them as anything other than chromeos - the security means you get prompted every boot (including reboots) that your chromebook is compromised. You have to hit a key combination (Ctrl-D?) to tell it you intentionally want to boot developer mode. Miss the opportunity and it goes into the recovery screen asking for you to insert a USB recovery key.

        Yes, this is intentional. Chromebooks are supposed ot be super secure devices immune to malware. So the bootloader checks the kernel and filesystem it's about to run to make sure they're original.

      There is some speculation that Apple will eventually ditch Intel and start using their own ARM chips at some point in the future. I don't think they'll do it next year, but I'm willing to bet that they'll have a non iOS product using an ARM SoC by 2020. Remember that before they went to Intel, Mac OS used IBM's POWER architecture and that they had an internal build of Mac OS that ran on x86 in development for years before it was ever released. I wouldn't be surprised at all to see that they were doing the same thing with ARM.

            I think the hold up is that ARM needs to be comparable in terms of computing power to Intel.

            I don't think "comparable" is sufficient. I think that to switch an OS where people primerally use propeitary native code to a new incompatible CPU architecture the new processors have to be substantially more powerful to offset the performance cost of the emulation.

            I find it unlikely that ARM will ever make a processor that is substantially more powerful than a regular desktop/laptop intel chip.

              It sounds wild, but look at their history.

              Apps built on Cocoa only needed a recompile to run on the new CPU arch when they switched to x86. Carbon-based apps could be a little more involved because it was their older API.

          • When Apple changed from 68K to PowerPC and from PowerPC to x86 there was a large jump in CPU performance each time. This allowed for the overhead of emulation without performance suffering too much. That performance jump doesn't exist now. In the best case ARM keeps up with the lowest end Intel chips, and Apple doesn't use the lowest end. ARM simply does not have the CPU grunt to emulate x86 without a massive performance hit.

            With our Chromebook, we've found that there are certain tasks that you want to do on a little 10 inch notebook, and certain tasks you don't. On a small laptop, a processor good enough for YouTube and Netflix is good enough. You don't want to run Visual Studio on a 10 inch device, so there's no need for a Core i7.

              Obviously, it doesn't matter to you that a supercomputer is faster than your desktop, if your desktop is fast enough. Similarly , if an ARM is fast enough for the things you do on a small laptop, it doesn't matter whether Intel offers a more capable processor or not - if the ARM suits your needs, that's enough.

          • The PowerPC was significantly more powerful than the 68K line, and I believe the Intel chips were significantly more powerful than PowerPC when they switched over. Moving up in power is complicated, since Apple insists on a smooth transition. Moving down in power would have many more problems.

    The issues about working with assholes aside, I suspect the life of a maintainer is difficult, not because it is too stressful, but because there isn't a good way to rotate the burden across people and time.

Is there a retirement home for maintainers? Can they come out of retirement and contribute? (perhaps at a lower level).

Plus, most people expect a lot more from a laptop than they do from a tablet. Does ARM support USB 3 at full speed? Can you hook up an SSD and have it run at full speed? Can you get gigabit ethernet running at full speed. Can the RAM be upgraded using standard DDR 3 or 4 memory sticks?

    • I installed Linux on my (really my wifes) Chromebook, dual boot. It turns out we never ever boot it to Linux. ChromeOS (aka the browser) does everything we want to do with it. We mostly view regular web sites, YouTube, and use Google Docs.

      It won't run Visual Studio, but it turns out you don't WANT to run Visual Studio on a 10 inch screen. Everything we would want to do on a little Chromebook works fine without needing any x86-specific software.

  • So 2016 will be the year of the ARM laptop, but there will be no Linux developers around to help maintain it. Does this mean Linux reached an apex point of mass that it can no longer sustain? That's like falling 2 feet from the finish line in a marathon because as you ran you got fatter.

    Looking at the latest in the ARM landscape, we have Apple A9, Qualcomm Kryo, ARM A57, ARM A72, and AMD A12. We can probably expect a small jump in Apple's performance next year along with a second revision of Kryo, but nothing competitive with Intel. A57 is being dropped for the fixed A72 since Apple screwed over ARM (tl;dr Apple shipped a new architecture in 2 years while ARM took almost 4 years for an inferior product -- everyone in the industry knows that design to shipping a new architecture is 4-5 years indicating either ARM screwed over all their non-apple partners (and themselves) by giving Apple a head start or Apple forced ARM to adopt a new ISA when they'd already had a couple years to work on int). Of all these architectures, I think only A72, AMD's A57 implementation, and AMD's A12 are worth focusing on.

    A72 is supposedly close to the performance of Intel's core M processors, but I'm willing to bet that the default A72 can't actually compete with Skylake's wide dispatch, SMT, and vector units. The biggest question in this area isn't actually the CPU so much as all the "uncore" parts surrounding it. Even if it could have these things in theory, the companies controlling most of the patents in this area aren't using the A72 (AMD, Intel, IBM, Oracle, etc).

    AMD's first generation of ARM processor (launching next year) is an A57 server part, but is probably going to be faster than most A72s in practice because it can be manufactured on a high-performance (rather than bulk) fab process and will have faster buses, faster memory, much larger caches, and even some parts of the core (like the branch predictor) may well be replaced with better systems while AMD's reworking the entire architecture for the new fab. This chip will probably be competitive in the low-power server market, but most likely won't be aimed at anything mobile.

    Not much is known about AMD's A12, but for the first time, an ARM company seems to be moving into the higher-performance mobile segment. AMD failed with bulldozer (and has taken the heat for beating that dead horse for the past few years), but they at least had the sense to hire Jim Keller to help them make a couple new, next-gen architectures. While AMD has money troubles, it's in the intellectual property sweet spot to be able to put together a competitive chip. This is the chip I think Linus is wanting, but it's been pushed to 2017.

    The complete unknown is Intel. They bought DEC and StrongARM was along for the ride, but they sold it in '97. They then made XScale only to sell it to Marvell in '06. I find it hard to believe that Intel's not experimenting with ARM design again. Even if they could make x86 compete in the low-end (atom has been a failure in that regard), convincing companies to switch will probably prove impossible as the current situation with lots of competing CPU providers works to their fiscal advantage. Apple won't be giving up the freedom to make their own chips (nor will Samsung). That said, I don't think we'll be seeing an Intel ARM chip before 2018-19.

    tl;dr -- the current chips can't compete with Intel. The ones that can don't launch until 2017 or later.

      I forgot to mention Nvidia's Denver core. They dropped it in favor of A57 and I don't think we'll be seeing it again for a while. The original reason for making it seemed to be for x86 emulation (literally the next generation of transmeta), but their lawsuit settlement with Intel sunk that ship leaving them to repurpose the architecture for ARM. I like the transmeta idea, but like bulldozer it seems a little less good in practice at present. I think we'll see something similar return in a few years, but for

    You missed it by that much!

  • Garter says there'll be 7.2 million chrome books sold in 2015. That's well below Windows Phone sales numbers and if anyone claimed win phone was taking over the world they'd be locked away. Worse, 70% of those sales are in the education market where they're just used as locked down web browsers which is fine but no kid uses it in the classroom and thinks "wow, I have to ask for one of these for Xmas".

    It's the netbook argument all over again -- most people's use case for laptops is web and email, and it doesn't really matter what processor or OS the laptop is running as long as it works with most websites and email sends and receives ok. There are assumptions there -- that video and other resources used by websites work correctly -- and there's room for some specialized apps like Netflix, but that's pretty much it.

    So Linux on ARM as a laptop? Sure. And it'll almost certainly be more reliable, run faster on equivalent hardware, and meet most people's needs who own laptops. There's no technical reason this couldn't happen.

    The reason it won't happen is that there's this ninety billion dollar company and this other one hundred eighty billion dollar company that both have a vested interest in this not happening. And they're really good (at least so far) at making sure it doesn't happen.

  • He also explained that one of the problems now is actually finding people to maintain Linux.

    Linus would have a much easier job finding great kernel maintainers if he was civil, objective, patient and kind on the mailing lists, rather than critical, cynical, foul-mouthed, insulting and belligerent.

  • "He also explained that one of the problems now is actually finding people to maintain Linux"

    Gee, if only you weren't such an asshole, Linus, that problem would've been a non-issue TEN YEARS AGO.

  • I'm looking for an ARM laptop:

    • Display: ~36cm, matte, resolution 1440x900 or greater
    • RAM: 4 GB or more

    • Firmware: the main firmware and all drivers must be 100% free as in freedom
