I added some convenience scripts to the config. Read the new tutorial here
The old one still works:
I put together a small virtualbox vm with a very minimal debian config with which I was able to compile a working kernel. This is for all the people who are running Windows, and want to try modifying kernels/initramfs's. As this is a minimal config there are some drawbacks (like it doesn't have a graphical interface), but you can always install additional packages, if you want to.
The VM includes: debian, build essentials, git, vb guest additions, mc, vim and codesourcery 2010q1 gnu-eabi. (it's larger than the simple eabi version, but can be used to compile non-kernel applications too)
First of all I hate both SunOracle VirtualBox and debian, but VB is free, and debian is lean, so they'll do the job.
To get the image running do the following:
First download and install VirtualBox
Next download the VM image: http://android.sztupy.hu/dl/KernelCompilerVM-1.1.7z and extract it. (it's a large download. If you can please put it up a mirror)
Mirrors: (thanks to the people mirroring it)
- http://www.multiupload.com/THJV19BJ9X
- http://bote.ro/sztupy/KernelCompilerVM-1.1.7z
After this run virtualbox, and import this VM.
Run the VM. The username/passwords are: root/root and kernel/kernel. Login with kernel. (you can always switch to root using sudo)
Next choose what kernel/initramfs you want to compile.
Here are some links to kernels:
The original sources can be found at supercurio's git:
Code:
git://github.com/project-voodoo/linux_gt-i9000.git
froyo-samsung branch
The kernel of the voodoo project can be found at the same place:
Code:
git://github.com/project-voodoo/linux_gt-i9000.git
froyo-voodoo branch
The ULTK kernel can be found at my account:
Code:
git://github.com/sztupy/universal_lagfix_kernel.git
Here are some links to initramfs files:
The original froyo initramfs can be found at supercurio's git page:
Code:
http://github.com/project-voodoo/samsung_ramdisks.git
afaik the voodoo initramfs is build using scripts from these images, so you have to apply them.
The ULTK initramfs can be found here:
Code:
git://github.com/sztupy/universal_lagfix_kernel_initramfs.git
For the rest of the tutorial I'll be showing how to compile ULTK:
First get the kernel sources using git:
Code:
git clone git://github.com/sztupy/universal_lagfix_kernel.git kernel
Unfortunately no copy-paste function is available, so you have to write this manually...
Next get the initramfs using git:
Code:
git clone git://github.com/sztupy/universal_lagfix_kernel_initramfs.git initramfs
If everything goes well you'll have two directoryes, called kernel and initramfs. Next we have to modify some values in the kernel configs.
Nano, mcedit and vim are installed, use the one that suits you best. (mcedit is the most user friendly)
Switch to the kernel directory and edit the Makefile there:
Code:
cd kernel
nano Makefile
Find the row that says
Code:
CROSS_COMPILE ?= some value
Replace it to
Code:
CROSS_COMPILE ?= /home/kernel/arm-2010q1/bin/arm-none-linux-gnueabi-
(if using nano make sure it won't add a line break into the row)
Next load the default config:
Code:
make aries_eur_defconfig
And edit it:
Code:
nano .config
We have to supply the directory of the initramfs. Search for the line:
Code:
CONFIG_INITRAMFS_SOURCE=some value
and replace it to
Code:
CONFIG_INITRAMFS_SOURCE=/home/kernel/initramfs/out
(this is for the ULTK. For voodoo the initramfs locations are "froyo-xxjp6" and "froyo-xxjpm" instead of "out")
if you've managed to do that too, let's compile the kernel:
Code:
make
If everything goes fine after a while you will have your shiny new kernel. Now let's get it to your computer, so it can be flashed:
First, you have to create a shared folder in VirtualBox. Simply create a directory somewhere on your computer, and add it as a shared folder in virtualbox. The name of the shared folder should be simple, for example "shr".
Next, you have to mount that directory inside the VM. To do this enter:
Code:
sudo mount -t vboxsf shr ~/share
After it has been mounted you can copy the fresh kernel to your host OS:
Code:
cp arch/arm/boot/zImage ~/share
If everything goes well you have a zImage ready at the folder you've just shared. TAR it, fire up odin, and flash.
---------------------------------
Now that you've succesfully compiled a working kernel try to modify it. You can use "make menuconfig" in the kernel directory to switch some kernel functions (like filesystem supports) on and off. You can edit .config by hand to add or remove some configuration values. And you can edit the files in the initramfs directory. After modifications you only have to enter "make" in the kernel directory to get your kernel inside the "arch/arm/boot/zImage" dir ready.
You can also copy files from your host OS, to the guest OS, by putting the file inside the shared folder and copying it:
Code:
cp ~/share/thefile ~/initramfs/copyithere
Hope this guide was useful.
Impressive, thanks. Even a noob like me can try this.

high time you start compiling kernels
tnx
its very usefull
Magnificent!
I just came to take a quick look, but the thread deserves a closer one.
Thank you for sharing knowledge.
Worthy of a sticky.
Hopefully this will solve all those "I want this in a kernel but not that" scenarios.
This is VERY nice for the devs.. but.. i think this will make this forum spammed with 69 diff kernels with just minor changes.. as with the roms
Its better to let other people brick their phone than you brick your own
Just kidding! I for one will try and compile different versions with different lag-schemes to find the fastest combination. Including /system with fastest reading. I think I will add a benchmark to the recovery menu directly. Benchmarking each mount for read and for write speeds. Maybe I can use backup/restore code and just time it without writing (cp to null). Lets get to work
Thanks sztupy!

Fluxbox/Openbox. However I don't see the need for one, if you're running the machine just for compiling.
Also, shouldn't gpm+guest additions solve the copy-paste problem?
E: Apparently not. Meh, stupid virtualbox.. sshd+putty then!
Awesome! Thanks for this sztupy! The more people we can get involved in this stuff, the better the end result will be. Always!

actullay i was looking for something light and minimal (with GUI, or at least something like PCman FM and gedit or kedit, im not good with emac, vi ) to play and compile AOSP, for now i do this with Kubuntu dual boot on my laptop. if i put a litghweight desktop on top of szytup's image and use it with VB, that would be great.
thank you !

I'd use a shared folder+IDE/editor/whatever on windows. But that's just because I have so awful experiences about X in VMs, things might be better nowadays
Thanks a lot sztupy, will try it now. Sunday is enough time for testing
Each morning i have a look at XDA and you have brought out a new very helpfully posting, kernel, rom or else!
So let me ask you one question: when do YOU sleep?

The advantage of using X is that afaik guest additions has copy-paste support, that would make modifying easier.
I also plan on making some simple scripts inside the default home directory one can run to communicate with the shared folder. After that we could provide simple scripts that you only have to put inside the shared folder, which will download, modify and run the compilation.
I have been working on getting ubuntu running natively with the netbook gui (unity) on the galaxy tab (7" touch display at this resolution is ideal). Kernel and filesystem are almost complete, but I need one last piece of the puzzle, if anyone has the galaxy tab hardware keyboard and know how to flash a kernel with heimdall could they join irc.droid-life.com/#modadroid-galaxy-tablet and catch my attention (lilstevie there too)
Here is a screenshot of netbook-launcher-efl running on the tab

Dualbooting isn't much of an option at the moment, unless with some bootloader hacks we can separate boot modes to boot the boot partition with no keypress or recovery position with keypress, as at the moment it just triggers a different init script in the initramfs, ubuntu has some differences at a kernel level

I'm going to have a look at this today for my Meego install, the Android init isn't passed anything by the kernel so it must look at some /dev or /sys entry to work out whether a recovery boot was requested.
I've certainly had no real problems replacing the Android init with an init script and exec'ing the renamed Android init from that to get a normal boot, the question is now how to make it useful by reading the bootstate.
As an aside, I see you were asking about the keyboard, I'm also interested in this as I have the same issue as you - i get a login prompt but can't login. I was thinking that getting a usb keyboard to work would be nice, but otherwise I'll have to make sure I bring the network up and either start adb or insmod an ethernet gadget driver (assuming such a thing will work with the Samsung patches).
Anyway keep up the good work

sounds like you are stuck in a similar position to me, any driver that is not the samsung android eth gadget does not want to compile for me, the path that i am taking is trying to get the wlan module loaded and using a script to associate it to my wifi network.

not at all bothered about dual boot on this project..
im absolutely excited about ubuntu working as a native os though, that would be amazing, if its anything like 'Dcordes' ( '@htc_linux' ) build for the HD2 this will be a real winner for the Tab, all the phone functions need to work too like texts and gsm, i guess if HD2 can do it then Tab can too..

[Guide] Compiling your own nightly kernels Quark/Blechd0se & Essential Git commands
Well Hello again another day, another do it yourself guide for the people like me with ORD
Search it up to see what am on about
Today there will be two guides they are very easy I promise - One on how to compile just the kernel image(zImage) and the other on how to use some common git commands.
Kernel Guide
1. Downloading the sources & packages needed :
Before we start we need to make sure you have the necessary packages required for you to compile the kernel.
If you already have an android build environment setup then we are good to go
If not then you can either use my guide and get an android build setup going just incase you want to compile your own nightly later on or you can just download the necessary packages required for compiling the kernel.
Packages needed - git-core, gnupg, flex, bison, gperf, libsdl-dev, libesd0-dev, libwxgtk2.6-dev, build-essential, zip, curl, libncurses5-dev, zlib1g-dev, ia32-libs, lib32z1-dev, lib32ncurses5-dev, gcc-multilib, g++-multilib.
So for ubuntu based system it will be -
$ sudo apt-get install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev ia32-libs lib32z1-dev lib32ncurses5-dev gcc-multilib g++-multilib
For arch linux -
$ sudo yaourt git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev ia32-libs lib32z1-dev lib32ncurses5-dev gcc-multilib g++-multilib
Most of the packages are found in the AUR repository so you need a frontend to AUR like yaourt.
Once you have the packages installed we are going to clone the kernel tree into our computer.
I feel it's best you make a new directory for which you will use to compile kernels.
Once you are in your directory of choice we can now download the kernel sources
For Quarx kernel - $ git clone https://github.com/Quarx2k/jordan-kernel
For Blechd0se kernel - $ git clone https://github.com/Blechd0se/jordan-kernel
One thing to note is after the git clone command you can name the folder in which the sources will be saved to.
For example git clone https://github.com/Blechd0se/jordan-kernel blechd0se. This will renamed the folder to Blechd0se which the kernel sources will be saved to instead of the default name of jordan-kernel.
2. Downloading the toolchain/s
If you have one of the rom sources (CM10, SB, CNA) synced up then you can just point the cross compile to that directory.
$ git clone https://github.com/Quarx2k/platform_prebuilt
Here you have a choice of two toolchains either the default google one (4.4.3) or the recently added linaro toolchain(4.5.4) by Quarx
3. Setting up configuration
Now cd into the kernel folder so for me -
$ cd ~/Kernel/Blech0se
Then run the follwing commands -
$ export ARCH=arm
$ export CROSS_COMPILE=~/<location of toolchain>
- For the linaro toolchain it will be export CROSS_COMPILE=~/Kernel/arm-eabi-4.5.4-linaro/bin/arm-eabi-
- For google's iw will be export CROSS_COMPILE=~/Kernel/arm-eabi-4.4.3/bin/arm-eabi-
make mapphone_defconfig
If you are compiling Blechd0se kernel then you can choose what process schedulers you want BFS or CFS the default is CFS.
To enable BFQ you need to do the following things
make menuconfig this will bring up a menu which you can use to customise the kernel if you know what you are doing this can also be used on Quarx's the difference is you don't have as much choice as in Blechd0se's.
Scroll down and select enable block layer then IO schedulers the scroll down to BFS and type "Y" a star will appear in the checkbox showing it will use BFS now.
Once that's done you can compile own kernel image using the make command
make -jx <maximum number of jobs>
Replace the x with the amount of jobs you want. I usually use -j8 but you can use higher but it can slow down you PC.
Read this post for more info on effectively using make -jx
You kernel will be finished into a couple of minutes to hours depending on the amount of jobs you used and how many cores you have in your processor.
Now we need to package the kernel into a zip to flash recovery.
I recommend you download one of Blechd0se's zips and modify it.
You need to delete the config folder if you don't want your overclock settings getting overwritten and also you can modify the updater script found in META-INF/com/google/android.
Then replace the zImage in the folder system/2ndboot/ with your new one.
You can find your zImage into the arch/arm/boot folder in your kernel source folder.
4. Updating and rebuilding -
To update your sources with the latest changes you can use the git pull origin command from the kernel source folder.
So for me it will be -
$ cd ~/Kernel/Blechd0se
$ git pull origin
Once it's being updated we need to first use
$ make clean
$ export ARCH=arm
$ export CROSS_COMPILE=~/<location of toolchain>
$ make mapphone_defconfig
$ make -j8
Credits & Thanks-
To XDA as always for being an awesome resource and playground
To Google for all they awesomeness
To Blechd0se for being an awesome kernel dev
To Quarx for his amazing work on the kernel so far
To thewadegeek for his guide which I have adapted this from Thank him here
Git Commands
The following git commands are the essential ones are feel that are needed to be able to use git effectively allowing you to help contribute back to the community...... With these commands you can help with things such as rom translation, bug fixes etc......
Commands -
1. git clone
This is used to clone a remote repository like here onto your local drive allowing you to edit/add files.
e.g
$ git clone https://github.com/Quarx2k/android_device_moto_jordan-common
This will clone the repository android_device_moto_jordan-common into a new folder called android_device_moto_jordan-common but if you want the folder to be called something else just add the name after the url like so....
$ git clone https://github.com/Quarx2k/android_device_moto_jordan-common Defy-common
Additionally, you can also specify downloading one branch by using the -b command you can also still has a custom name for the folder by putting the name at the end of the branch name. E.g
$ git clone https://github.com/Quarx2k/android_device_moto_jordan-common -b jb_2ndboot Defy-common
2. git
HAHA again
Last one for a party
I just finished syncing CM10 sources, I'll do this one too now
Thanks, you rock!
mark，thanks

Thank you Kayant for this nice guide Hope to see some additional dev's soon
Maybe you can add how to push a commit
And if you only want to rebuild modified modules you can simply run the "mmm" command, safes time
Btw: BFQ and CFQ are I/O-Scheulders, CFS and BFS are process schedulers
When I used to have defy (good old days) this was something I want to share with everyone but I couldn't because I lost my defy when I have doing some progress in custom kernel. Then I lost track of this great community and stop to make things for defy. It's great to see this kind of tutorials for help other users as well. As always, very thanks kayant!!!

Thought I might add. on that make -jx command, x should be your max threads + 1 -- eg, I have a quad core w\o hyper threading so I use 5.
use the "nproc" command to find out how many threads you have
the make jx is different than sync jx, where sync jx is how many files you'll concurrently download. I figure most of us know that, but I figured I'd make the distinction.
number of cores + 1 is recommended on a lot of faqs; your results may vary, but using j5 (my recommend setting) versus not setting it (j4 by default, i think -- needs fact checking) speeds up compile time by 20-30 minutes (Quarx CM 10). using too many threads will slow you down and using too little is inefficient and thus slower.
Thank you very much for your informative guides Kayant always learn something from it and really appreciate it:thumbup:

You're completely right about the kernel and time -- but for full rom builds and a Funtoo "emerge -uDNav world" it helps. I just saw that j8 and thought "My dual core Athlon 64 would hate me if I did that".
Great guide as always
That does it.

That's the best thing I ever did. I hated XP, wish it was more like Win2k -- I'd gladly pay for Win8 if it had a 2kPro interface. Win2k was awesome, and the only Windows OS I'll give praise to.
I recommend starting out with Ubuntu or Mint (Mint based on Ubuntu, not Debian). There's better support for Ubuntu and distros based on Ubuntu. After about 4-6 months, once you start learning apt, the command line (bash), and some Linux basics; switch to Pure Debian or Mint Debian -- much better than Ubuntu, but not as user friendly (or AptoSid\Sidux -- they're based on Debian Unstable (Sid) -- which is actually pretty stable, ya just gotta be able to fix it if it breaks). I've found that the easiest way to learn it is to just do it. Reading up on it only goes so far without putting it to practice.
After a year or so, try out Gentoo\Funtoo and you'll learn a lot about Linux -- but those distros are not for the faint hearted and require time and dedication to get a GOOD working environment. Once you have it how you like it, it WILL be the fastest desktop you can use with the fastest compile time -- well, WILL should be shall or can. I'm about to turn my old compile PC into a generic x64 Funtoo box (one of my 64's is AMD, the other Intel). A generic build will allow me to use the same base system on both PC's and allow me to rebuild them to they're specific architecture after its all set up. It took me 3 tries to get a good Gentoo box running -- miss one step in that install guide and you can be up that creek.
11 years on Linux now, 9 years with only maybe 25 boots into Windows -- past 10-15 were to flash an sbf and to reboot back to Linux -- so glad I stumbled across the sbf_flash Linux tool. Last time I booted Windows was after installing Win7 and its drivers....seriously, all I've done is installed it and the drivers and haven't booted it up since. I've used Red Had, Fedora, Ubuntu, Arch, Mint, Debian, Suse, Mandrake, Gentoo, Funtoo, Sabiyon, Aptosid, Sidux -- after using all of them, I find that I prefer Debian\based systems (not Ubuntu\based systems -- I actually don't like Ubuntu, well, since 0910 -- it was a good distro up until then imho). And I like Funtoo for the source based distros -- I've messed around with other source based ones (Sorcerer, Arch) and like Futnoo over Gentoo and the rest in the end.
//You might already know enough Linux, I'm just posting what I think is the easiest way to start using and, therefore, leaning Linux.
///I'm also surprised that there isn't an XDA based Linux distro -- designed by XDA members to make it easier to get into Linux\rom hacking
rom compiling with all the tools we all need an apt-get away.
EDIT
I've been meaning to ask, Do any of you programmers have any good books to recommend? I'm finding myself of the border of power user and programmer and need to start learning some code skills to cross over. I'd like to learn something C, Python3, and Java; but there are a ton of books on them and I'd like a recommendation from someone HERE who knows a bit of programming and what they'd use to learn nowadays.

I use Arch Linux ATM and a love it but yh I have read about gentoo and how you can build it to your system.... Once I get a new PC in the near future hopefully very soon am going to try that and freebsd... Thanks for the advice
Let's Go ^_^

Never tried BSD. Arch was OK, but I started on Debian, jumped around different ones for a few years, stuck with Ubuntu 7.10 for 6 months, hated their update, and been on Debian or Mint Debian ever since; testing or Sid usually -- I transcode my DVD's and stable has older codecs . Arch was a year ago for a month -- if I gave it more of a chance I'd probably like it as much as I do Debian. I've used almost all major distros, desktop environments, window managers, etc; but I always find myself back with Debian\XFCE -- it just works for me.
If you didn't know, Debian has a freeBSD based distro as well. That'll make it easy to try out BSD in an Debian style environment.
Hoped I could say the same. School is a real Linux killer.
Even for software that has a linux port, they only give us the installer/license for the Windows version. :/
PLC and robotics software tend to only run on Windows anyhow. As 3D drawing.
Always have the need to change my partition setup Linux-Windows after installing such an application on my laptop.
I am now using Ubuntu for 3 years. I like the look and don't want to spend time on my PC installation so it's good for me . I can imagine that it's different if you really want to get to know Linux or Unix.
What I hear most for learning to program (me not so much) is just try to do what you plan to do with it(an android application, ...) and searching how to get there. Don't know many that read books. Except for guidelines for memory management and security for example later on.
I've been programming for nearly 20 years. Only had a few classes in the basics. The rest has been trial by fire. Use Google a lot to figure out how to do stuff, but I can't really TALK about code as I don't know what to call some of the things I do. I highly recommend taking formal classes and reading books.

That's what I've been doing up until now, but Google only helps so much -- I can do a search on learning Java and come up with 1000's of faqs, guides, ect -- weather its worth reading or full of it is unknown too me since. A good book can be worth its weight in gold. With a bad internet faq, ya might as well change the faq's a to a u and bend over, cause that's what you're doing to yourself by learning from bad sources.
While I don't know what apps you're using, I know that some apps have a license isn't limited to the platform -- the Win License works on Linux\Mac\Unix as well. Or just use the Lin version and not feel guilty since you have the Win license .
Ubuntu was great until it started getting too bloated for my tastes -- and they're XFCE editions usually use much more resources than doing the same thing with Pure Debian installed from the command line up. On compile\dev boxes you want as little running as possible for obvious reasons. Not to mention the UI can greatly change from release to release with Ubuntu. Buntu was my 2nd Linux to run; Debian first -- Learned more on Ubuntu then went back to Debian. Pure Debian can be daunting if its your first distro.

Thanks. I'd be taking classes if I could. I don't qualify for any grants and I don't want to go for a loan because of the uncertainty of being able to pay it off.
Something I'm seriously thinking about doing is this -- free online classes from MIT. That has to be good information.
@All
I'm thinking of starting a generic x64 Funtoo box and get it to where XFCE is working, Nvidia graphics (all I buy is Nvidia Cards ), Android SDK is up and running, and all the required scripts, apps, udev rules, etc are already installed set up (repo, sbf_flash, apktool, etc). Then upload that as a zip so all you'd have to do is extract the zip to a blank partition, edit its fstab, update grub, set the build environment variables to your own, reboot, set users\passwords, and recompile the system.
I'm already going to do all of that except for the upload as a zip part -- I have 2 64 bit pc's -- one amd, one intel -- so I have to build it as a generic 64 in order to use the same system on both boxes. I was just wondering if anyone else would be interested in something like that once its all done.

I normally don't post my PM's, but the last half on this one I sent out might be useful to some of you looking for the essential git commands
I have a couple of good sites I use for github reference. Here & here
Typing "man git" in the command line has helped me a lot as well. I've learned most of my Linux knowledge by typing "man name_of_program" and Googling what it said that I didn't fully understand -- especially with video encoding, ffmpeg and mplayer are some long reads, so is git. Git also has a "git help name_of_git_command" program that's helpful as well.
There's also a few threads on the Defy forums dedicated to helping out people trying to do exactly what you're wanting to do. The nightly builds link is a really good place to start with -- contains pretty much all you need to know to be able to compile roms. Kayant's an awesome dude and really helpful. His threads are great for users wanting to learn and\or contribute back.
[Guide] Compile your own nightly builds - AOKP, CM10, CM9, CNA, Slim Bean, P.A.C
[Guide] Compiling your own nightly kernels Quark/Blechd0se & Essential Git commands
I learned git from forums like the ones above, those reference sites and man pages\help program. Took about a week of trial and error before I got the hang of it. I still have a hard time remembering to start a branch before editing crap after the initial sync .
Honestly, the hardest thing to do, in regards to PA, is adding in FM. Almost everything else Defy\Bravo related just cherry picks right in with no\ very little and easy to fix conflicts. The FM commits are old and those files have changed a lot from when Quarx & Maniac did the patches -- especially between Quarx's and PA's current.
Cherry picking is pretty easy, navigate to the base directory -- like frameworks/base -- then its "git cherry-pick a_ton_of_hex" and it'll either pick right in or you have conflicts. If I get conflicts, I use the app "git-cola" ran from command line in the /frameworks/base directory; and its a gui app that'll list what files have conflicts (and a lot more) -- I then open up the conflicting file with tkdiff (or whatever diff you like) and fix the conflicts, "git commit -a" (saves changes), and push to github. If you don't get conflicts, just commit and push. Btw, the ton of hex is all the hex code next to the commit on github.com, review.cyanogen-mod.com.
Making changes on your own is done simply be navigaitng to the base directory -- frameworks/base for the android_frameworks_base repo, device/moto/mb520 for the Bravo repo -- and opening a terminal, starting or pointing to a branch (git checkout -b name_of_new_branch is a good command to run before you do anything -- checkout -b n_o_b creates a new branch and places you on it), then do what ever changes you need to do, then do "git commit -a", enter a description, and push. Once you have different brances going, you can use "git checkout name_of_branch" to switch between them. Read up on branching, cause theres a lot to it.
There's a lot of different ways to do git, and my way might not work for you.
Good luck and have fun reading -- you'll be doing a lot of it :silly:

I've been fairly bottlenecked lately by final exams but I'm working on a few things as well. Been trying to work on the cm11 build but my knowledge in that area is limited so I've been learning as I go in that aspect. At minimum I'm gonna try building 4.4.3 based on @Angel_666 's source tree so we've at least got the newest code base to look at.
As far as stock-base, I'm trying to create a custom kernel similar to KT747 on the S3, also the idea was given to me by another user to **** around with swap-space to maybe push the ram a bit further. I'm also looking into potentially having KSM but I wouldn't bet on it for a stock-base
When I can manage to update Pimpdroid it's gonna be on the newest base, I'm also looking into potentially unifying the builds so I don't have to constantly create blind builds and get bombarted with "bla bla bla is not working". Slight problem though in that I've heard reports the LTE variant has an extra gig of ram. (If anyone can verify, that'd be great) as for new Pimpdroid features I'm keeping almost everything not pertaining to the kernel secret for now
But yeah. On a comment from another thread, if anyone cares to form a team to finally get a decently stable aosp build going, I'm willing. I can walk you through what I know if need-be, and to one who may be more experienced than me, I'm a quick learner.
Cheers
Restl3ss,
thank you for replying to this thread.
i failed to mention my inability to build/compile etc. which may or may not be remedied by an answer
to the following question.
Do I need a 64bit PC to begin building/compiling/ndk/sdk/git-hub stuff etc.
If yes then I'm screwed but I can still test, even risky/dangerous stuff.
If no then it will take me a little to get set/started but i can still test, even risky/dangerous stuff.
My own interest is specifically the kernel, being hands-tied by the issue mentioned above is, well.....
any thoughts you have would be appreciated.
as for things like zram/swap I had thought because of the massive amount of rewriting that that was
inevitably an internal card/chip/storage slayer?
You sir are clearly the more experienced of the two of us, though i do hope to change that or at least
catch up.

To build anything newer than 2.3 gingerbread you do need to be running a 64 bit OS. However, that being said, even the Intel atom chipset supports 64 bit so it may just be a matter of your OS, and since you need to have Linux anyway to build, I highly recommend dual-booting your computer with 64-bit Kali Linux (I highly recommend Kali as opposed to Ubuntu for building. Any time I've tried to build on Ubuntu it freezes a minute into the build and I have to restart the machine. With Kali it ran flawlessly the first time, though it was a little bit harder to set up the initial build environment)
You're right about swap space being an sdcard slayer, so really it's up to the individual whether the shortened life span is worth the performance increase. Ideally you could set it up with extSD so at least if the card dies you're not left with an expensive slab.
I'm more than happy to teach you how to build from source if you want. I'm not an expert at it myself but I know enough to get by. Running my own unofficial cm11 on my S3 with a few cherry-picked things
Cheers
hmmm
hey hey,
so i'm boned pc wise for now. However on the atom chipset being 64bit capable brings my next question, is it possible
to setup a build environment on this tab at the very least for kernel?
my kali install on the laptop i have [2nd hand 32bit] is boned so i'm dl ubuntu right now.
Concerning the build environment question; that is the nature of my experiments right now.
what i'm trying to do is structure the ramdrive into something approximating Linux.
I collect genuinely static binaries wherever i can find them [x86]. I read that the virtual terminal is disabled in android
kernel,[trying to get verbose boot, somethings i need to see], but i don't know if that's entirely true as with some
tinkering i've been able to display kill/sigterm/shutdown output. I am currently attempting to set root/daemon
into ramdrive as well as relocate /system/etc&bin to /bin&/etc proper. I'm picking up some basic sh,.rc scripting.
And i am attempting to get foremost functioning [forensic tool]. I am working on getting a capable laptop but it's iffy.

I seriously don't recommend ubuntu for building, if kali isn't working for you you could try another debian distro possibly? that being said though, just because ubuntu freezes during build for me doesn't mean it will for you, different hardware and what not (though I do build from a virtual machine running on top of my mac mini) As for setting up a build environment on the tab itself, it theoretically is possible with a LOT of tinkering, but the major problem there is that the android terminal is seriously neutered compared to a standard linux box, we don't even have apt / dpkg, which if you look at a build guide, is absolutely necessary to get the tools necessary to build. However, if you could get a full fledged linux environment running on this tab such as debian or ubuntu, I don't see why it wouldn't be possible, however slow.
your experiments intrigue me, though you'd be looking at a very long road to turn android into a full fledged linux environment, I would very much like at minimum to have apt / dpkg capabilities

by the way, how exactly is your kali installation screwed up? Because I just remembered that when I was setting up my build environment I somehow ended up breaking GNOME and had to install KDE via command line to get a GUI running again

dependency hunting almost always sucks haha.
for kali, are you using the live CD or are you doing a native installation?
if you're doing live, root/toor should work. if you do an actual dual-boot you set your own root password
kali is a distribution meant to be run as root, the root account is enabled by default and has its' own home directory

GOOD MORNING !
my pc is 32bit, my understanding is 64bit pretty much is about longer file names?
have kali 32bit going, try for kernel at any rate, would you help me with;
1- kernel source?
2-toolchain?
don't get me wrong, i am reading my ass off [just fell off....true story :silly:], but WOW....
if i'm doing this right so far i grabbed angel_666's stuff and trevd's stuff tho trevd's cm10.2.
i first just want to compile kernel w/no changes to get the hang of things.
OH yeah kali-mini ramdrives up and leads you to doing a network install, there must be some
useful toys in that. if i find/do anything neat, i'll post

Back before the Linux discussion, you asked whether the p5200 (LTE) had 2gb of ram. Yes it does. It amazed me that in no place does Samsung mention this, not even in the publicity on their website. But the task manager shows total ram of 1.89mb. I suppose that is why my machine is so blazing fast and I never have the complaints that I read about.

64 bit is more than just file names, there's also a lot to do with memory management. There's also 64-bit only applications
the kernel source and toolchain you should be able to find at the tab 3 development by learning developers thread, for toolchain though you can pretty much just use the same things you would for a standard cm11 compilation
so if you're on a 32 bit system,
Code:
apt-get install bison build-essential curl flex git gnupg gperf libesd0-dev libncurses5-dev libsdl1.2-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop openjdk-6-jdk openjdk-6-jre phablet-tools pngcrush schedtool squashfs-tools xsltproc zip zlib1g-dev
and if you're on a 64 bit system it's the same as above + a few extras, so
Code:
apt-get install bison build-essential curl flex git gnupg gperf libesd0-dev libncurses5-dev libsdl1.2-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop openjdk-6-jdk openjdk-6-jre phablet-tools pngcrush schedtool squashfs-tools xsltproc zip zlib1g-dev g++-multilib gcc-multilib lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev
if you're running a debian distro (such as kali) you're gonna want to add a couple repos to sources.list.
Code:
gedit /etc/apt/sources.list
and add the following lines (one might already be there, if so just skip adding that one. duplicate lines cause problems)
Code:
deb http://ftp.de.debian.org/debian sid main
deb http://ftp.ca.debian.org/debian/ wheezy main
take note that if you're running a debian distro the package phablet-tools listed above won't be installable through apt-get. so install every other package listed above with apt-get install, then for phablet tools you're gonna have to grab the .deb + its dependancies and install it manually. once phablet tools is installed along with the rest of the above run apt-get install on all of them just to make sure they all say the newest version is already installed. If done correctly you now have your toolchain. do a reboot via the terminal.
Take note that installing these packages on a debian installation WILL break your GUI (i've tested this in 3 different distros, always happens) so when you boot up after installing the above tools you'll just have a command line. Dont worry. Log in as root and type
Code:
apt-get -o=APT::Force-LoopBreak install kde-full
let that run its course then once it's finished reboot from the console. when you boot up again you should have your GUI back (though maybe not the one you had initially. This will function just as well though)
if after the reboot you find yourself back into the console, log in and type "startx". if that doesnt work, type "startkde". KDE should boot automatically but occasionally it goes back to console, one of those two is guarinteed to boot your GUI.
If for some reason when trying to log into KDE it just boots back into the login screen, hit the button in the lower left pannel of the login window next to power and switch it to "failsafe". Login like normal, you'll get a terminal window. (xserver is running but the gui is not fully) type "startx" or "startkde" in this window. Try them in that order. One of them will boot KDE like normal.
If all went well, bam, you're in your desktop and you've got your toolchain.
(I seriously recommend debian for building. Significantly more difficult to set up but ubuntu has a platoon of problems with the brunch command)
I know that was fairly long winded haha, but that should give you everything you need. If you get gedit isnt installed at any point just grab it with
apt-get install gedit
also, I highly recommend building from source for a device or two that already has CM available before you try to build based on angel_666's thread. it's best you're comfortable with the process, as working a port is a lot more intensive. Adding some unmerged gerrit code and rebuilding will also make you more comfortable with the source file structure.
also, keep me updated on kali mini if you don't mind, I'm intrigued
hey hey

You shouldn't be concerned too much with the kernel number difference, modern android is built on 3.4.xx where as the latest desktop kernel is 3.15.xx.
Setting up a build environment on Debian doesn't necessarily break gnome persé, it breaks whatever GUI you had initially. So really, if you wanted gnome for example, install Debian with the stock DDE at first, break it with the installs, then install gnome via command line
Your source should be fine, keep me posted

But yeah. On a comment from another thread, if anyone cares to form a team to finally get a decently stable aosp build going, I'm willing. I can walk you through what I know if need-be, and to one who may be more experienced than me, I'm a quick learner.
Cheers

Hope I can join your Team since many Teams here on XDA always reject ME

Back before the Linux discussion, you asked whether the p5200 (LTE) had 2gb of ram. Yes it does. It amazed me that in no place does Samsung mention this, not even in the publicity on their website. But the task manager shows total ram of 1.89mb. I suppose that is why my machine is so blazing fast and I never have the complaints that I read about.

About the Shield TV PVR Project
I wanted to use my NVidia Shield TV not just for gaming and Netflix, but did not like the idea to loose the (in my view) really cool wifi remote and gamepad by switching to 'that other full android' image that is currently available on xda. So i decided to jump on the road and add those few additional features I was missing to the stock system by myself..
After some (many) hours of work to get the nvidia supplied source packages trimmed down and fixing bugs in the kernel, I can finally say its running pretty good now!
Here is what is working right now:
- A full kernel compile can be done in just about 3-8 minutes contrary to more than one and a half hours when using the unmodified nvidia package
- The stripped down development package I built is only taking about 1.5 GB of harddrive space, there is no need to download all of these 20+ GB of mixed stuff from the slow nvidia servers anymore, no need to wait for the repo tool to unpack and etc - its just fetch and compile a bootimage right away.
- I have added full NTFS (r+w) support to the kernel, so you can just plug-in any ntfs formatted harddrive or usb stick and use it like the fat32 formatted drives that were already supported.
- I have added DVBAPI support back into the kernel so you can plug-in a supported DVB-C/DVB-S/DVB-S2/DVB-T/DVB-T2 tuner stick and use it to watch, record and stream live TV from your shield - full PVR powers baby! (I had to patch the base kernel to allow that as there was some 32/64 bit ioctl compatibility issue that I think was one of the reasons why nvidia did not include dvbapi - it took a long time googling around to get this working..)
- I have built the latest tvheadend server version from source aswell, on my shield it gets started using a bootscript and its really easy to install using adb
This is my current setup:
I have connected 3 DVBSky DVB-C/T/T2 USB tuner sticks to a powered USB 3.0 hub and plugged that into the shield. Since there were no drivers for my usb stick brand available, I have patched the dvbsky branch of the kernel tree with a backported version of these drivers. (For those of you that have different brand sticks, there are 2 other branches available, one with all the stock kernel-supplied dvb drivers, one with all the drivers from media_tree). It is now easily possible to
watch live TV (using Kodi with tvheadend htsp plugin) with full EPG etc
stream live TV to the kids room (my kids are using kodi installed on a fire tv stick that is connected to an old 19" lcd screen)
stream transcoded (bandwidth saving) live tv to my tablet and smartphone over the internet
record tv shows on demand, timers can be programmed using a smartphone (tvheadend helper app) aswell as through the kodi interface
All these features are in heavy use by my family right now and without any real impact on the overall speed of the shield console - read: completely transparent in the background! (I have attached a 500 GB USB 3.0 hard drive (ntfs formatted) to the shield for storage of the recorded tv shows - obiously.)
Get yourself a Shield PVR
Just grab a linux-supported tuner stick and a harddrive, flash one of the precompiled kernels and install tvheadend from my androidfilehost area - it surely is not for the fainthearted as there are currently no step-by-step instructions, but I think everyone with a little knowledge on how to use adb and fastboot can do it.
Of course I will try to help out if you run into problems, you can post your questions/suggestions/bug reports into the issue tracker or to my thread at xda.
Contribute
If you want to say thanks and help continuing my work you can hit that donate button on my androidfilehost area, it is not in any way required tho. If you want to contribute code/patches/ideas - just do so using the usual channels (issue tracker, xda thread).
How do I get set up for development?
Check the official repo wiki page, I have added some scripting code examples and etc to the wiki there.
Check my twitter account aswell for latest updates and a preview video showing my actual shield in action!

Great work!
I tried to follow the link to the wiki on your bitbucket, but only get a message that I don't have access to it. Maybe some permissions that should be changed?
This is excellent work. What usb tuners are supported?

i just tried the version compiled on the 28th on retail firmware it doesnt boot
Wow! This is EXACTLY what I wanted to do with my Shield TV but didn't think it would be possible. Is that dvb-s2 by chance?

hm, please try to install the developer firmware first, and i would recommend the build id 11c80e6 for first testing - I will try to make it work on retail when everything else is a bit "matured" of course

dvb-t/t2/c/c2/s/s2 - doesent matter as long as there is a kernel driver for the tuner available. and if its not already included in the kernel you can use the media_build release where a lot more tuners are supported - its a little tricky to get it running because with media_build you would have to find out which tuner.ko file you need to "insmod" - so better try the "static" build id 11c80e6 before anything else and please post a dmesg capture if it doesnt recognize your tuner.
Haven't actually purchased a tuner yet, but am thinking about doing it soon now! I'll try and find one that's well supported under Linux already.
THE BUILD SYSTEM HAS BEEN FIXED, NEW BOOTIMAGES WERE UPLOADED AND THE REPO IS BACK ASWELL. THANKS FOR YOUR PATIENCE.
sorry for that, I made a silly mistake in my script when I built the stripped down environment and published it for the first time - i now have pushed the fixed source to the repo and a full set of new bootimages to the androidfilehost page. it should be all working now but please report any problems you may find as I cannot test everything by myself (because of lack of hardware, obviously)
could you enable Webcam drivers too so we can use Skype video

+1 to this.
Also, since you're compiling the kernel, it might be worth adding the systemless root.
at the end of the day, it makes no difference without the supersu app, so users can decide to have root or not, by installing the supersu app.

all available webcam drivers have been enabled in the media_build branch, you will have to find out which .ko modules to insmod though. the stock kernel
does not have much (if any) drivers for webcams I think.. hmm.

Does this mean you are using nvenc for transcoding? Or are you not using any hardware acceleration? How is that performing (how many streams can you transcode simultaneously)?
I am really looking for a solution to make transcoding easier. From what I've seen with using nvidia's nvenc is that the CPU is only decoding the streams, encoding is completely offloading, giving a massive decrease in overall server load. Now I know the new nvenc has a hard limit to allow up to 2 streams transcoding on normal GeForce gfx cards, but I wonder if the same limitation applies to the Tegra X1 chips..
In short: hardware transcoding makes this the ultimate tvheadend server/set top box!
PS: Also, the links in your Wiki entry to your Androidfilehost profile don't seem to work. I think they are account links (only for you when you are logged in). The correct link seems to be https://www.androidfilehost.com/?w=files&flid=48701. Maybe also add it linkable to your OP?
Can you please explain how exactly do we apply your file?...
Is it enough to just flash the zip file with twrp, or do we have to do something else?

to all asking how to do this.
you don't need to root for this, however, you need to unlock the bootloader
once the bootloader is unlocked, you need to boot into fastboot mode, and flash the boot.img.
you will need root to install tvheadend though, and knowledge of command line.
If we're nice maybe we can ask nop to package it up into an apk wink wink.
I managed to play with it for a while, and installed tvheadend, just can't figure out the web-ui password!
thanks again for the great work.
let me know if I can help in anything, I'm not a developer, but used to be a Solaris sysadmin back in the day.

try to manually start tvheadend from adb shell for the first time like this:
Code:
/data/dvb/tvheadend -C -c /data/dvb/tvheadend/hts
(the -C will let tvheadend enter into intial setup mode where you can enter passwords etc. for subsequent starts skip -C.)
i only want to give some feedback regarding webcam drivers.

unfortunately i didn't have luck getting them to work with skype. i think there is something missing inside camera hal implementation. maybe zulu can give us some usefull hint how to fix this.
