Best Computer OS for Android Development?

Hey guys, I'm new here and new to Android Development. I would like to try my hand at it. Can you guys suggest the best OS for Developing Android Apps.
Linux (Which Distro)
Windows
Thanks
Andrew

I to have been curious as to the best linux distro for android development. I'm not looking for afull blown linus os...more along the lines of dsl for android and app development. I have only dabbled with linux, mainly dsl and phlak livecds. I want something a little more capable then that.

UBUNTU IS THE BEST OS because android is developed under linux with java base...
if you tray windoze you must to adjust a lot of thinks and make compatibilities... don´t complicate and try UBUNTU 10
An answer of one ubuntu lover!
sorry somtimes my english is poor

Linux is best os android development application. Android is an operating system based on Linux and a robot body or synthetic. It is open source as a Java library. It is a software stack for mobile devices because it includes an operating system and middleware, application key.

I think the best Linux for Developing Android is Ubuntu. There is a new version, 11.04. Try it

i know linux is the obvious choice for android development as it has the same base as android. i also understand ubuntu is the most popular of the linux brands, but i dont really need a full blown linux os. i curently use my mobile-ap for internet with about 2 bars if that...so internet speeds are slow. i dont want to spend alot of time and bandwidth downloading a linux os with features i will probably never use. or is there a light version of ubuntu with just a basic environment i need to develop for android?
as for my other computing needs, im still a windows fan!

Is Fedora on GNOME 3.0 a good platform for development?

yea i like linux mint its more user friendly than ubuntu

Since you might be using Eclipse as IDE, there shouldn't be too much difference using a windows or linux OS.
We're using windows and we're satisfied...

Just try different OSs. You'll notice windows is slow when compiling Java. Why is that - the OS, or the usual virus scanners sitting on it - don't know. I'm pulling my hair right know why my Macbook Pro on a 7000 rpm drive is much (3x) faster to compile than windows XP on a 10K rpm drive. My office buddy's telling me Linux is faster then windows.

Wow... some of the answers in this thread are just... wow...
Ok listen up people!
For just pure development it doesn't matter which OS you choose. You can code just as well in Linux, Windows or Mac since they all run the JDK, Eclipse and the Android SDK just as well. HOWEVER:
Linux has some advantages over the two:
1. The Android emulator will run better on certain versions of Linux depending on how they are set up. The AVD works by using an emulation technology called qemu which is now integrated in the Linux kernel giving it direct access to the processor thus improving the speed of the emulator significantly. Windows and MacOS don't have qemu integrated in their kernel as far as I know therefore the emulator works like S**t.
2. Linux distributions by default are optimised to work faster on hardware than Windows. Take note of the words "than Windows". MacOS is highly optimised to work as fast as possible on Macs therefore it can't really compete in this category. But for PC users, if you invest the time and effort to make your Linux machine tweaked accordingly to your hardware settings it will blow windows away when it comes to processing speed, therefore enhancing the quickness of your IDE as a result.
Now that we got that out of the way, I do have a warning: Linux Is Hard To Configure Properly! Unless you know exactly what you are doing you will brake it over and over and over again until you get it working. If you really must use Linux, here are the distributions I recommend for developing Android apps:
Linux Beginners: Ubuntu - any version above 10.04 I think. Take your pick at what works best for you
Linux Intermediate: Spend some time configuring a Slackware Machine with Eclipse + ADT + JDK + qemu. You won't be sorry.
Linux Advanced: Gentoo or Archbang depending on preferance
Linux Experts: The bloody hell are you doing on this thread?

Could you guide me how to take back up of only videos on my Android device
using own made program or application software.
Means from where to begin ?
What to cover first ?
File system of Android ?
Or direct using system calls I can copy videos directly ?

You suggested its worth time & effort to properly setup Slackware it would be worth our while. Ok found u page2. Let's see is the needed software list still valid 2015?
Where can I go for support setting up Slackware for android development.
Plus FYI can't watch tutorial video be.cause Flash no longer supports Linux.

I have UBUNTU 16.04.
I've noticed a lot of people saying to use Ubuntu 10. is that because the post is old or is the 10th generation Ubuntu the best for android development. i also am a noob. i can root, i have successfully flashed a lg stylo once with katana rom. i still use it to this day,,,,, bc my gf "accidentally" broke my 500gig hdd that i was booting windows ten from via usb on my dell inspiron. i was using mainly odin and lg flash tool which i rem was hard to get up and running on Ubuntu which if i rem correctly is why i went to windows when i am flashing. Any suggestions or refferences would help greatly. i fig if im starting over id better do it the correct way. My end goal is to try my hand at learning android development. Ty LOVE THE SITE

Does it not compile on ARM or what is the holdup? Can an ARM build of wine still run x86 windows binaries? I can see getting this ported into android/davlik gui might take some time but what about running it in like an X server on the phone and vncing to it from the android ui

As far as I know, Xorg conflicts with surface flinger, so the only option is to run a vnc viewer to connect to the x server. The upside is that it's local instead of across a network so it is every bit as snappy as native Xorg. The downside is (at least in my experience) that compositing and special effects don't seem to work over vnc.
I wasn't done, but my cat head butted my phone lol..
Anyway, once you've set up a full emdebian environment using something like botbrew basil, I don't see why work couldn't start on porting wine and testing it and Windows applications. I know that's already in the works according to the article earlier in the thread, but I think this was could also work and you're definitely on the right track

Good question, but honestly, I don't know... Maybe someone else knows...

What do you guys think About wine on android x86 project?
Sent from my LG-P880 using Tapatalk

Any update?

Right now, if you have an X86 Android phone, you can install the following to get Wine on Android:
1. XServer-XSDL - the best X server for Android
2. Linux Deploy - good set of chroot distros
3. SSH client - I like VXConnect
Here are the steps:
1. Start up XServer-XSDL.
2. Deploy a chroot using Linux Deploy with ONLY SSH. You don't need X, Framebuffer or VNC
3. use SSH client to ssh into your distro, default username: android ; default password: changeme
4. change your password
5. sudo apt-get install wine <-- this will grab the Wine package for your distro
6. export DISPLAY=:0 <-- tells your distro that your X server is local and port 0
7. for your first Wine run: winecfg
8. Press Tasks button to get out of SSH.
9. Select XServer-XSDL from the tasks list and you will see the Wine config starting
10. Accept whatever the config is
Now, Wine is prepped and ready to run on XServer-XSDL.
Tab over to your SSH session to start stuff up and then tab over to XServer-XSDL

[Q] Native Linux on phones

What phones can boot into and run a desktop ARM Linux distro (such as Arch, Slackware, Ubuntu or Debian) natively, with call and messaging support?

Ubuntu Edge.

The closet you can get is with Ubuntu Edge but it is still under development and will not be available for a some time.
I am sorry I can not post the links yet in the post but you can google for the "Ubuntu Edge" and you will get enough reading material about the project.

There are also some solutions with VNC and a VM in which you run a desktop Linux. Might not be what you want, but you would have a Linux running on your phone.
The main problem is going to be drivers, which is why a ARM Linux can't just be booted. Someone would need to be merging device specific drivers into the linux, test it, debug it and so on, which doesn't make sense if there are so few people really wanting it. And as you can see with Ubuntus try on that: It is a lot of development needed.

It's possible to dual boot Maemo (to use it for phone features) and Ubuntu (desktop) on Nokia N900.
It's also possible to dual boot Windows Mobile (for phone features) and Ubuntu (desktop) on HTC HD2.
On the other hand, these Indian tablets boot and run Linux:
w w w .youtube.com/watch?v=n1tC8uSR0og
And have phone features:
w w w .techulator.com/resources/9492-Datawind-UbiSlate-7C-Edge-tablet-Full-specifications-features-online.aspx
If anyone tested Linux with phone calls on those devices, please tell.

A long time ago I installed Gentoo Linux on an ARM based hx4700 iPaq; it worked but ran so slowly it wasn't much use. The specialised Linux distros Familiar and Angstrom ran much better, as they were specifically designed for handheld devices. Granted phone specs are way improved now, but is there any real advantage running a full-blown Linux on a phone.... surely Android is basically a Linux distro optimised for phone specs (and chargeable apps, etc...). Would it be less work to port apps you need to run on Android instead - if that's your aim? Although it may be worth doing just for the sake of it....

Full-blown Linux offers the advantage of being in control of the operating system. You choose the tools you need. Android is less secure (backdoors, apps reading your data) and mobile apps generally feel like crippled desktop apps. For example, apt-get is much more comfortable to use, you just type the packages you need and it downloads them, no need for searching inside categories of app market (and all of them are free with full functionality with no ads). You can use the same scripts you wrote for your PC. It can be tweaked to run really fast (low resource usage apps written in C vs Android's Java), and you choose your desktop environment (e. g. a tiling window manager with the right apps literally flies on an old machine, RAM used on system start with Xorg running equals 20 MBs). Also, there's full filesystem encryption.
Mobile hardware is more or less the equivalent of a Pentium 2 / 3 / 4 desktop PC, which is enough for full desktop app experience.

Im glad i found this topic.
Thats not new to me...
I think the questions to add are:
- How to fully remove Android to Install Linux
- Can i install all the Drivers needed?
So that i can use: Modem(phone); WiFi & GPS under Linux.
-Is it possible to revert to Android?
- Minimum Requirements to Run Linux and What Distro?

Use ADB on Android device in a Linux chroot / proot to control other Android device

On a non rooted Samsung Galaxy tab 2 7.0" I have the app GNUroot Debian installed. This is a chroot (actually it is called PRoot, see below for a description) Linux distribution - currently Debian 'Jessie' - with a terminal. I have installed the android-tools-adb package from the Debian Jessie repository. This means the chroot environment has access to the tablet's network hardware.
Now I would like to control another device (I have a non rooted Huawei Ascend Y300) from the tablet using adb inside the chroot terminal. I managed to do this through WiFi by first connecting the phone to a pc and run the terminal command 'adb tcpip 5555'. Then, on the tablet in the GNUroot Debian app terminal running the command 'adb connect xxx.xxx.x.x' gives adb control from the tablet over the phone through the local wifi network. Nice!
It would be even better to manage the adb control between two android devices from a chroot / PRoot environment without the pc, for example using an On The Go cable. Assuming non rooted devices. The tablet in question (Samsung Galaxy tab 2 7.0") has usb host capabilities. So in theory it could be done with a usb On The Go cable connecting the two Android devices.
Questions:
Is it possible to use adb within the described chroot / PRroot environment to run commands to controle another Android device, when both Android devices are connected through a USB On The Go cable?
Does a chroot / PRoot environment give access to the usb port as host?
Information:
The reason for this question is the development of an app on my tablet, using the Android IDE app, which must be tested on other (non rooted) Android devices. Preferably from the tablet, preferably without a pc.
Description of PRoot from 'proot-me' repository at github.com:
==
PRoot is a user-space implementation of ``chroot``, ``mount --bind``,
and ``binfmt_misc``. This means that users don't need any privileges
or setup to do things like using an arbitrary directory as the new
root filesystem, making files accessible somewhere else in the
filesystem hierarchy, or executing programs built for another CPU
architecture transparently through QEMU user-mode. Also, developers
can use PRoot as a generic Linux process instrumentation engine thanks
to its extension mechanism, see CARE_ for an example. Technically
PRoot relies on ``ptrace``, an unprivileged system-call available in
every Linux kernel.
The new root file-system, a.k.a *guest rootfs*, typically contains a
Linux distribution. By default PRoot confines the execution of
programs to the guest rootfs only, however users can use the built-in
*mount/bind* mechanism to access files and directories from the actual
root file-system, a.k.a *host rootfs*, just as if they were part of
the guest rootfs.
When the guest Linux distribution is made for a CPU architecture
incompatible with the host one, PRoot uses the CPU emulator QEMU
user-mode to execute transparently guest programs. It's a convenient
way to develop, to build, and to validate any guest Linux packages
seamlessly on users' computer, just as if they were in a *native*
guest environment. That way all of the cross-compilation issues are
avoided.
PRoot can also *mix* the execution of host programs and the execution
of guest programs emulated by QEMU user-mode. This is useful to use
host equivalents of programs that are missing from the guest rootfs
and to speed up build-time by using cross-compilation tools or
CPU-independent programs, like interpreters.
It is worth noting that the guest kernel is never involved, regardless
of whether QEMU user-mode is used or not. Technically, when guest
programs perform access to system resources, PRoot translates their
requests before sending them to the host kernel. This means that
guest programs can use host resources (devices, network, ...) just as
if they were "normal" host programs.

Do you want a KVM (Kernel Virtual Machine) enabled kernel for your Android phone/tab?

Hi. Can someone that compiles kernels compile one with KVM enabled and make it available to download for various popular devices? I'd love to test this out on ARM. This would really make these machines appealing if you could spin up VMs on them especially considering how much RAM they have today. There aren't many ARM devices as powerful as the Samsung Galaxy S9 that run Linux and can be tested with KVM. You could even run a different version of Android or Linux in the VM or try BSD.
This was already done for the Intel x86 based Zenfone 2 and as a result, it can run x86 Windows 10 32/64-bit editions, Mac OS X, BSD and any Linux distro full speed in a VM. Of course this is x86 and much more refined than virtualization on ARM and you don't have quite the OS selection on ARM either.
I'd like to see how well the new ARM Windows 10 performs on these Galaxy phones. It would be a great alternative to running Windows 98 in QEMU slowly. Windows 10 ARM runs Office 2016 and Photoshop at decent speeds on some of the latest Snapdragon SoCs.
Though, from what I've read, there will be some issues running Windows initially. ARM QEMU with KVM currently doesn't support the VGA display mode that is required for Windows 10 on ARM.
I was thinking of starting a project to do this for various Android hardware besides the Zenfone 2. There are a number of x86 tablets from companies like Dell or Nextbook that would really benefit from a KVM enabled kernel but ARM phones would benefit as well.
For those that want this feature now, here is a list of current retail Android devices with KVM support and the various custom ROMs/kernels available that enable it. If you would like to see this feature enabled in your device's kernel please reply and do not hesitate to request it to your custom kernel developers.

If you know of any other devices with KVM enabled kernels (ARM or x86) please let me know and I will add them to this list.

I might have to purchase an ASUS Zenfone 2, as I've wasted the whole year trying to get Windows 7, 10 running on my Android phone at anything beyond a snail's pace. The main problem is that KVM hardware virtualization is turned off in, like, every smartphone on sale in the market! This is bad brain - SUCH BAD BRAIN!!! My phone provider would not even respond to me on this issue.
I bought the first ever ARM64 laptop @ £999, but had to return it to the shop because it never booted up any Linux live USBs/DVDs. Since then I managed to get an ARM64 Linux distro - with a KVM-enabled kernel - running on the Raspberry Pi 3 B+ (thanks to help from a woman!) only to find that -enable-kvm is incompatible with qemu-system-aarch64's graphics options.
So what might the problem be exactly...? Well, the qemu-system-aarch64 generic -M virt machine type has no graphics output built into it - very clever!!! So we have to use -device VGA as an add-on to get VGA output. That will then allow snail's pace running/displaying of Windows 10 ARM; however, KVM happens to not be compatibile with this display mode - or perhaps any kind of display mode on aarch64 - due to the "VGA framebuffer" not being emulated (whatever that means!) by Qemu perhaps. The alternative is to use a different display device addon. We have -device virtio-gpu-pci, which allows you play around with the bios at near-native speeds - but the moment you boot from there into Windows 10 ARM it blackscreens cos' Microsoft did not put any virtio graphics drivers on their OS. So, basically, we are stuffed!
Ubuntu tells us "Ubuntu/arm64 can run inside the QEMU emulator. You can either do this fully emulated (e.g. on an x86 host) or, accelerated w/ KVM if you have an arm64 host." - yet they have no shame in omitting the fact that their installation runs with -nographics!
-display type none
Do not display video output. The guest will still see an emulated graphics card, but its output will not be displayed to the QEMU user. This option differs from the -nographic option in that it only affects what is done with video output; -nographic also changes the destination of the serial and parallel port data.
-nographic
Normally, if QEMU is compiled with graphical window support, it displays output such as guest graphics, guest console, and the QEMU monitor in a window. With this option, you can totally disable graphical output so that QEMU is a simple command line application. The emulated serial port is redirected on the console and muxed with the monitor (unless redirected elsewhere explicitly). Therefore, you can still use QEMU to debug a Linux kernel with a serial console. Use C-a h for help on switching between the console and monitor.

Therefore, I seriously doubt we can get even an RDP option on our Windows 10 ARM guest, alas. And, to add insult to injury, there is no sign of a Surface Phone or any Android software that might allow us to run Windows 10 ARM on our modern smartphones. What a bad time to be living...

Now I'm curious. How did you get KVM working on your Rasberry Pi 3 B+? I compiled QEMU from source using a modification of your instructions and couldn't get QEMU to even start with KVM enabled. What Linux distro are you using on the Pi? What linux did you use as your guest image? What was your exact qemu command line?
I wouldn't expect the ARM Windows 10 laptops to run any Linux yet. They're too new. We may need to wait years. The Windows RT devices were just secure boot unlocked a few months ago by someone from here and they still can't run any Linux.
Honestly, you probably are just better off getting a Zenfone 2. With the kernel mod, x86 Windows pretty much "just works." I just wish QEMU had a virtual battery meter so the VM could hibernate when the phone's battery gets low.
As an aside, I have a few Atom Baytrail Windows tablets that are quite similar to Android models and it's quite amazing what I can do with them out of the box when compared to Android. A few of them have virtualization enabled out of the box so all I need to do to use a VM is install VMWare, Virtualbox, Virtual PC, etc. and it "just works". No hacking, no flashing custom kernels, no command line tools at all. I've attached a picture of my Nextbook NXW8QC16G running Windows XP in VMWare and showing virtualization enabled in the task manager. The other picture is running Windows Server 2012R2, a 64-bit guest OS.
Your mention of virtio gives me an idea: Isn't it possible we can compile the virtio graphics driver for AARCH64 and somehow inject it in our ARM64 Windows image? If we did that, would Windows then be able to be used with ARM64 KVM acceleration? That guy who made the ARM64 Windows QEMU blog post already compiled the virtio disk drivers for AARCH64 and was able to get the installer to install to a virtual hard drive. Maybe all we need are ARM Windows compiled drivers for the rest of QEMU's special emulated hardware. I use the x86 Windows QXL driver with Windows 8.1 on my Zenfone 2 and it seems to work. Though, I had to boot with the VGA video mode first and install it via device manager manually.
Also, if you want an NT based OS on emulated x86 on ARM, have you thought of trying something older than XP like Windows NT 3.51 or 4.0? These were designed for 386/486s so should be more usable on emulated x86 QEMU than something like Windows XP. Office 97 works on Windows NT 3.51 and Office 2000 and maybe even XP and 2002 will work on NT 4.0. Softmaker Office 2008 also works somewhat on NT 3.51. Obviously Windows 98 may also be faster but it sounds like you prefer NT so these may be an option. If you install Windows NT 4.0 Terminal Server Edition, you will even be able to RDP into your emulated machines. Windows NT 3.51 also has an optional edition with remote, multiuser support called Citrix Winframe but I was unable to find an Android Citrix client that can still connect to it. (they're all too new)
I think we're starting to see the limitation of devices marketed as "phones" They're not an open computing platform or standard like the PC or even Macs.
We really need some kind of open standard firmware for phones like the UEFI/BIOS on PCs and an OS to go with it. It would be great if there were some kind of "open", generic (not neccessarily open source) OS that let you install drivers after being installed like Windows. Android is sort of open but not the hardware and good luck buying a device that will have an unlocked bootloader and get custom ROMs. Plus, you can't run anything other than Android and maybe another linux if you are lucky. I dunno, it scares me that these phones may become the defacto computing platform when they are so closed and proprietairy. At least with a PC, I know I can install the latest OS and be up to date for at least 15+ years if I want to be. We need that for phones but it just doesn't exist yet.

Update: I found a work in progress WDDM Windows driver for QEMU's VirtIO 3D GPU driver mentioned here:
https://www.phoronix.com/scan.php?page=news_item&px=QEMU-3D-Windows-Guests
The source code for it is here: https://gist.github.com/Keenuts/199184f9a6d7a68d9a62cf0011147c0b

Well it looks like our prayers are answered and our dreams came true. Thanks to the folks at limboemulator.weebly.com, there is now an ARM KVM enabled kernel available for the Snapdragon based Samsung Galaxy S8 and S8+
The latest Limbo PC Emulator even has KVM support even with the ARM builds.

These are only for Exynos
our snapdragons have a locked bootloader they will never work for us
dd the following lines to file: arch/arm64/configs/​exynos8895-dreamlte_defconfig
CONFIG_VIRTUALIZATION=y
CONFIG_KVM=y
CONFIG_KVM_MMIO=y
CONFIG_KVM_ARM_HOST=y
#from the command line type:
make clean
make mrproper
make ​exynos8895-dreamlte_defconfig

Does anyone know how to compile/use Virtio drivers for Qemu-system-aarch64?
"You are welcomed to check the branch: https://github.com/virtio-win/kvm-guest-drivers-windows/tree/arm64
Instructions for build machine (using community edition of VS2017):
https://github.com/virtio-win/kvm-g...vers-including-arm64-using-visual-studio-2017
Soon will be integrated to master and we will distribute the binaries.
Best regards,
Yan."
https://github.com/virtio-win/kvm-guest-drivers-windows/issues/177
If the above works as a GPU for KVM then we might be able to pursue the Samsung Galaxy/Limbo solution?

I found out a lot of phones have KVM already enabled:
*Xiaomi phones, i.e. Pico F1 and Mi 8 with up to 8GB RAM (Mi 9 and Black Shark 2 have 12GB RAM)
*OnePlus phones, i.e. OnePlus 6T with up to 10GB RAM (McLaren Edition)
*Realme 2 Pro with 8GB of RAM
To find out just check the following file in a kernel source code:
https://github.com/MiCode/Xiaomi_Kernel_OpenSource/blob/dipper-o-oss/arch/arm64/configs/defconfig
KVM is disabled in all Huawei and Samsung devices by default. And Huawei cannot be unlocked/rooted anymore.
However, I found out how to compile custom ROMs for Samsung, etc.

KVM enabled on Mi 9 Xiaomi. What's the latest on a VM build we can use to build kernels etc.? Great idea here I proposed this AM and was shot down by a bunch of old school devs that think you should go through the pain of setting up a build env yourself that no one can replicate.

I probably need to update it, but for a VM you can try Builduntu here: https://nathanpfry.com/builduntu-virtual-machine-android-rom-compiling/
XDA post: https://forum.xda-developers.com/showthread.php?t=2585828
That should save you some trouble hopefully. ROMs and kernels will compile.

Thanks!
It's great someone is forward thinking enough to put this together. Much appreciated!
What updates do you suggest?

Seems to be running in VM

Seems to be running from Virtual Box after the Extensions was added. Almost got the torrent downloaded but had to revert to the Google Drive and change to .html extension to download. Virtual Box 5.2.30 is the version.
Didn't sleep at all just got it booted which is a success at least. Thanks for providing.

Has anyone tried to turn on KVM on Xiaomi phones?
I tried to compile the kernel with the included KVM on Xiaomi Redmi Note 5. It compiled without errors, the KVM folder appeared with the files in the folder with the compiled kernel. But the phone with this kernel hangs on the logo. Maybe it's because of the miui?
To enable KVM, I added this to the defconfig:
CONFIG_VIRTUALIZATION = y
CONFIG_KVM = y
CONFIG_KVM_MMIO = y
CONFIG_KVM_ARM_HOST = y
One person with the help of such a compilation was able to enable KVM on their phones (Honor 7c pro, honor p20 pro, samsung galaxy s8), and the KVM works. Windows 10 arm launched.

so does kvm works in honor 7c pro(as u have mention) ? And launch windows fastly?
also i wanna enable kvm in my redmi note4 .is it possible ? And How?

@TFGBD
Hi bro,
I have some questions that I hope you will answer me.
Note: My English language is bad ? ..
I was looking for how to activate the KVM feature on the LG G4 H818P phone to run Windows 10 ARM quickly on the phone, I have read that all ARM processors that work with Cortex-a15 or higher support KVM feature, but mobile manufacturers do not include this feature in the system, So,
I want a simplified way to activate this feature on my phone ?,
I want to know how fast I will get after activating KVM in Windows 10 ARM simulations ?,
will the method work with any device or each device has a method designated for it ?,
and
do you need experience ?,
How dangerous is it on the device?,
Do I need root privileges to benefit from KVM?
And will I need to reinstall the system again or only the kernel ? .
Thanks, bro ? ...

It's not simply a matter of enabling the KVM support in kernel. The vendor has to enable virtualization capabilities for the SoC in the firmware. On most (if not all) mobile platforms this will be disabled. Although there have been exploits that enable you to overcome that and they have been confirmed to work (think Lumia 950[XL] custom UEFI).

Hi all,
Anybody has enabled or knows of somebody enabling KVM on samsung galaxy tab s6? (4.14 kernel)?
I tried enabling the virtualization options in the kernel config, kernel compiles and device boots as normal but /dev/kvm does not appear...
"The vendor has to enable virtualization capabilities for the SoC in the firmware"
@konradybcio What do you mean by "firmware"?
Bye

Had a look at the kernel boot log and found the following line:
kvm [1]: HYP mode not available
So it appears the kernel is running in wrong mode and cannot operate as hypervisor
Probably samsung's bootloader (firrmare!?) does not allow it...
