Chromebooks May Get Apple Boot Camp-Like Windows 10 Dual Boot With 'Campfire' (xda-developers.com)

Google is reportedly working on a secret project to get Windows 10 running on Chromebooks. XDA Developers' Kieran Miyamoto reports on the latest developments surrounding "Campfire" -- the Chromebook equivalent of Apple's Boot Camp. From the report: Earlier this year, a mysterious project appeared on the Chromium Git. The Chrome OS developers had created a new firmware branch of the Google Pixelbook called eve-campfire and were working on a new "Alt OS mode" for this branch. We have since confirmed this Alt OS refers to Microsoft Windows 10 and found evidence that it wasn't just an internal project but intended for public release.

The developers have reworked the way in which they distribute updates to a rarely-used section of ROM on Chromebooks called RW_LEGACY. The RW_LEGACY section on a Chromebook's ROM traditionally gives users the ability to dual-boot into an alternative OS, but it is something of an afterthought during production and the section is rarely updated after a device leaves the factory. Now, with Campfire, Google will push signed updates to RW_LEGACY via the regular auto-update process, so firmware flashing won't be a concern for Joe Public. A recent commit for enabling Alt OS through crosh with a simple [alt_os enable] command indicates that it will be a fairly easy setup process from the user's end too.
We may expect to see the first demo of "Campfire" at Google's upcoming Pixel 3 launch event in October. Also, the report notes that the Google Pixelbook won't be the only Chromebook with Campfire support, citing "mentions of multiple 'campfire variants.'"

  1. Run Windows under Linux by Tough+Love · · Score: 3, Interesting

    It's the new thing, run Windows under Linux. Linux GPU virtualization is even good enough now to run AAA games in a VM. For most of what you do... browsing, social networking, viewing media, the experience is better under Linux now than Windows (e.g., you will never get an upgrade nag while watching a movie.) Not to mention Microsoft won't be spying on most of what you do, except of course for what runs in the VM. You want that to be less every month.

    Dual boot is out, sandboxing Windows is in.

      Dual boot is out, sandboxing Windows is in.

      I agree. I had setup my old Apple laptop to dual boot but then quickly realized that I'd need Windows for one thing and then MacOS for something else, usually at the same time. I could duplicate some functions on both so that I would not have to switch as often but then I'd have to find a way to keep those things synchronized. As soon as I was able to get a computer capable enough to run Windows in a VM and not have it compromise what I wanted to do in MacOS I never dual booted again. I just keep the Windows VM running in the background, and when I need Windows I can bring it full screen with a key combo. Switching back to MacOS is another key combo. If I want Linux then I can bring that up in a VM too, and now I have three operating systems running simultaneously on one computer and I'm able to switch between them all with a key combo.

      I used to dual boot my desktop computers all the time. Now I have a couple old computers I keep in Windows (which I honestly don't use often, at least not for work), one running Linux, and one running MacOS. Computers are so cheap and powerful now that I don't see much utility in dual booting any more. I'd think people with a need for more than one operating system would rather just get another computer or run what they need in a VM.

      What linux virtualization solution would you recommend for hosting Win10 + games with gpu virtualization?

      I haven't tried it myself yet, but there are multiple reports of success with Ryzen+KVM+GPU+W10, for example this one.

      You say its 'good enough' to run AAA games. What sort of performance hit am I really facing?

      My impression is, very little. GPU virtualization gives the guest OS direct access to PCI registers, the overhead can get very close to zero. This report from 2014 shows overhead consistently less than 3%, often a lot less, and remarkably, sometimes actually faster in the VM. I'm not sure how that last one works.

      The big overhead for VMs tends not to be CPU, but memory consumption, make sure you have enough to make both host and guest comfortable. You should be fine with 16 GB, but more memory is always better, I'm liking how it feels with 32 GB. You will want a separate SSD for Windows, I think, but that's not going to break the bank.

      Do some games "just-not-work" What sort of stability loss am i looking at?

      Again, I'm not doing it myself right now (I have too many unplayed games already without a bunch more from Windows) but I see multiple reports of success with GTA 5 and I don't see any horror stories. My feeling is, your system as a whole will be more stable than it is now, and the VM+Windows part of it will be exactly as stable as now.

      I've got an i7 and a gtx1080, if that's a factor.

      Though I am a newly-minted Ryzen fanboy, I love Intel too except for their business practices. VM stability seems exactly the same for Intel and AMD. That is very cool. Number of VM crashes I had over the years on Intel or AMD: exactly zero, and I really thrash those VMs.

      What's the situation with multi-monitor support with something like this?

      Dunno. I'm waiting for your report. The question you ought to ask is, what's the situation with sharing the GPU between host and guest? Lots of active discussion on it. It's a thing, and multi-monitor passthrough is a thing.

      And peripheral pass through? (usb headsets, usb controllers).

      KVM has good USB passthrough, but for mouse and audio where performance is not an issue you probably want the virtual devices. There are a whole pile of online resources on it, e.g. here and the community is active. Mostly people seem to be using libvirt and virt-manager. I don't, I just read the man page and run KVM/QEMU from the command line. Do that only if you enjoy that kind of thing.

      There is a great and supportive community here.

      Before plunging to GPU passtrough, you should test your games with Wine and DXVK. I've been playing No Man's Sky and Fallout 4 with Wine+DXVK in 1440p for a quite a while now, on i7-6700 and GTX1080. Expect some graphic glitch here and there

      Speaking of which, I installed Vulkan support on a Debian box a couple days ago and it came up without rebooting or even restarting X. How cool is that? Feeling lucky, I hunted down and installed the Unity Editor. Wow, it works great. Ran through all the tutorials in about 15 minutes, they are pathetic but you get some orientation. Basically, you learn to push the play button and you learn to drag and drop assets onto game objects.

      Jumped straight into a demo project and was confused for hours, but eventually broke through to the other side. This is just great, I will double plus unconditionally recommend it. At that point I immediately lost all interest in Windows gaming, why run them when you can make them? To be sure, I haven't got time or energy to make a commercial one, but talk about fun and bang for the buck: $0.00 down and $0.00 a month gets you endless entertainment. Now bringing my kid up to speed on it, who will quickly surpass me. I'll just have to be content being the scripting consultant. I have no problem at all sending $$$ in the general direction of Unity Technology, I just love what they did. Does anybody know about this?

      BTW, this seems to be Wine based because of all the dlls, and it also includes Mono as the scripting language, a convincing answer to the question "is Mono really compatible with C#?".

      Also ran a bunch of fan-made Linux Unreal engine demos, they are awesome, and Unreal may well be the better engine for the moment. I'm hardly complaining, Unity is way more than enough for me, and Unity Editor is said to be more intuitive. I will be able to weigh in on that myself UDK for Linux lands, which looks imminent.

    you do not see much effort in reverse.

    Not true, actually. Microsoft now officially supports and invests a lot of money in running Linux both under the Windows desktop and in the cloud. I would go so far as to speculate that Microsoft now has more money invested in this than the sum total of all the work that went into Wine.

    But the elephant under the rug is, it's actually better to do it the other way: run Windows in a vm, that way you can keep your critical work and data entirely out of the hands of Microsoft. Microsoft knows this and now has a whole bunch of money invested in various efforts to forestall it. To be honest, it's hard to see that as a bad thing, it's the nearest thing to honest competition I have ever seen from that gang.

    On at least one model of Chromebook you can load Libreboot and eliminate the risk of accidentally wiping out your Linux install. But it would be nice to be able to keep ChromeOS for those times when you want to interact with Google, and have a Linux install next to it which is completely free of them, and have it stay there like a good install should. I am not even slightly interested on running Windows 10 on the bare metal, like many other commenters in this discussion.

    If you want to know what hell is like, run Windows 10 on a celeron N4xxx or N3xxx CPU. They do sell these, mostly HP 15-series laptops btw so I know firsthand. That's the chip of choice for almost all chromebooks then you add the pathetically underperforming 32GB flash storage device (SSD is far too generous of a title) and 4GB of RAM and it take about 4 minutes to fully load and open and render one page in any web browser.

      I was the original alpha tester for Windows 10 on Bay Trail Chromebooks, and the first implementation was absolutely hideous. Windows To Go technically worked then, but it took minutes of disk thrashing to do anything because Bay Trail has some serious design flaws that slow down both USB and SD transfers enormously (though for different reasons). Once it got to the point where it would run natively from the eMMC, things got quite a bit more usable, but while it is possible to get Windows 10 up and running on a 16 GB eMMC, there isn't enough space for maintenance of any sort. This meant moving things out to a flash drive and symlinking all over. I actually had it working for a few months that way, but then of course a major feature update broke it. 32 GB would actually be adequate for the OS, and everything else can go onto a flash drive without symlinking.

      Bay Trail (N28xx and N29xx Celerons) was shipped half-baked by Intel rather than miss deadlines. They couldn't get the SD card I/O to work reliably above 25 MB/s, so they just hacked it so it can't even try. Too many simultaneous calls to a USB drive can start blocking each other, dropping transfer speeds into the single digit kilobytes per second range. This wasn't particularly a Chromebook problem, it was all Bay Fail devices (except those that added chips to work around the problems).

      Ultimately I sold it, and bought a Haswell Chromebook instead.

    When they first came out they came with Linux and they were an absolute revelation. Small fast and perfect for mobile computing for people who weren't tied down to the Windows ecosystem. Then Microsoft leveraged their ability to charge whatever they wanted for Windows licenses to "encourage" vendors to dump Linux and ship a handicapped version of Windows instead. Once that handicapped version of Windows became standard, Microsoft started dictating hardware specifications and as a result we were stuck with shitty atom processors, tiny amounts of ram, and tiny hard drives for many more years than necessary going with the pace of technology. NetBooks went from being a great mobile PC option into just a shitty small laptop that you bought for your kid to wreck.

    It's been a couple of years, but last time I checked 3d performance and compatibility with vmplayer was vastly ahead of KVM.

    A couple of years ago was exactly when GPU passthrough was under heavy development. Now there are multiple reports of success and I just don't see horror stories. I have no doubt that VMware player was way ahead at the time, I have tremendous respect for their ability to make stuff work, but they also like to wrap it in layers of cruft that you can't avoid. That's a turnoff for me, compared to KVM, which is accessible at every level, including the one I prefer which is simply the command line. I'm perfectly capable of setting up my own disk images, thanks. VMDK is completely irrelevant to me.

    Most folks use KVM via virt-manager or similar, I have no data on that. They seem happy, so I am happy for them. I'm happy for you too. :) The world is a better place with VMware in it. At the very least they keep the KVM devs on their toes.
