Hey guys,
Hopefully someone can help me.
I need to add Config_USB_VIDEO_Class=y to the stock kernel.
I am trying to compile a new kernel for the Samsung Galaxy Note 2 GT-N7100. I have a few questions and any help would be greatly appreciated.
I have built the kernel from the Samsung Open Source file and the Android NDK 4.4.3 toolchain.
There is only one change that I needed to make in the kernel configs. I needed to add Config_USB_Video_Class=y.
I am left with the zImage and a few .ko files. How do I flash the new kernel to my phone. Do I need to create a boot.img file? If so, how?
Again, Any help is greatly appreciated.
Thanks
Let me know if I am in the wrong section.

Hi BlInK311,
You came to the right forum section
Yes, you need to build a new boot.img for this. You can extract it using http://forum.xda-developers.com/showthread.php?t=1771347, if you have your phone rooted, but the easier way is to extract it from a Stock ROM
After this, you combine your kernel and the Ramdisk from the stock boot.img to make a new boot.img, and flash it using ODIN
This might help as well:

As the title suggests, is there a kernel for the P605 which will allow SElinux permissive, and therefore allow full linux chroot installs to be completed with relative ease.
I am aware of a permissive kernel for P600, http://forum.xda-developers.com/showthread.php?t=2590311
but assume this will not function for the P605.
If not can the same steps used to make the P600 kernel permissive be applied to a P605 kernel?
Looking for the same kernel
I'm looking for the same SELinux-permissive kernel for P605.
You definitely can't use the P600 kernel as it is for the Exynos variant (P600/01) while ours (P605) is the Quallcom CPU.
Unfortunately the P600/01 was released around the world first with most devs getting the Exynos version. Little developement has been done for the P605 but there has been a little. Just not for an SE-Linux permissable kernel, at least not here on XDA...
Will try to build it myself
I've been thinking of modifying and building the kernel myself. The problem is that there are several kernel source codes on Samsung's website for SM-P605. (I can't post the link here) My device model is SM-P605 without any suffixes so I think it's the first kernel that I should choose.
I think modifying the kernel into SELinux permissive should be as easy as changing a default value in one of the source files and then I can build the kernel using the instructions that come with it. Fingures crossed!
One more thing: in the source code that Samsung provides there are two directories, one kernel and the other platform do I need to build the platform too?

Hey Rhesus007, just wondering if you have made any progress?
Im really in need of a permissive kernel, however i have no knowledge of how to make it etc.
Thanks.
Just dropping back in the thread, still hoping this will happen, as linux on this tab would be really useful imo.
Someone with some dev experience might be able to use the methods used on the note3, which has the same snapdragon 800 soc to achieve this. The basic steps needed to modify the kernel are described in this thread
http://forum.xda-developers.com/showthread.php?t=2471416
if nobody with experience can do this, I might give it a try, but that might be a recipe for disaster....

I've got no experience with this, if you could attempt it, I'm sure a lot of people would be grateful!
For those still looking.

Hi,
I've successfully rooted my UK galaxy tab pro 12.2 SM-T900 (using a P900 img as the T900 one bricked it), I'd like to try running linux via chroot but I think I need a custom kernel to set SELinux to permissive.
Since there don't seem to be any in existence I think I need to build one from source as described here (I can't post links):
graemehill.ca/compiling-permissive-android-kernel/
The build # on my device is T900XXUANI1
however on the Samsung open source site this particular version is not listed.
opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=T900
I'm not sure if they're supposed to be the same thing - Should these versions match? Will I break something if I download the source for T900XXUANB5 and compile that or is that the right version to download?
Thanks

You can use bonuzzz's Custom PRO-VTFB. But if you really want to create your own, you can use the B5 kernel. However, that kernel has been followed by two firmware upgrades.
Thanks, so there's no problem using the p900 kernel on the t900? It's not something I've ever done before and I don't really know how much difference there is between various kernels

You might loose the automatic screen rotation, but that's the only difference. I use it as an alternative to cm-11, together with bonuzzz's Custom ROM 1.01 the most debloated TW ROM available. There is also a cm-11 kernel with enabled VT, but same thing here you will most likely loose the auto rotation.
If anyone is interested, i sent a request to samsung via their open source website on the day I posted this thread, asking for the XXUANI1 source. Got an email back today to say it's now available on the website. I haven't tried doing anything with it yet though!
Hey guys, I'm starting this thread in the hopes that somebody can explain to me the following:
I wanted to play around with the Galaxy Grand's kernel source (just to get an idea of how a kernel works) so i downloaded it from sir @GHsR 's repo (stock branch)... now, the unpacked size is a whooping 478MBs... what i don't get is how all that fits into grand's 8MB boot.img's ramdisk.
could somebody help me out here?

Cross compile it with toolchain (for example : Uber Toolchain
Get that here : https://bitbucket.org/matthewdalex/ I generally use arm-eabi-5.x version )

hey man.... i think you misunderstood me. I'm not planning to work on kernels (hopefully yet), i just wanted to know how the source fits into the boot.img. nevermind, i got my answer from two friends : most of the source is optimised and stuff... some other stuff like legal mumbe-jumbo & documentation is ignored while compiling, and it's done. hope somebody who was searching for this kind of info finds it.

Hi,
I am trying to port LineageOS to an unsupported device, an IBall Slide Cuddle A4.
Here's the guide I'm following : https://fat-tire.github.io/porting-intro.html
This is the part where I need help:
"Add the blobs to the vendor/ directory
Once you have a working recovery, it's now time to get CyanogenMod building and working.
The first thing to do is to get all the proprietary, binary blobs into the vendor/ folder, along with a .mk file that will include them in the final build.
This requires three steps:
Create extract-files.sh and setup-makefiles.sh scripts to pull those blob files from the device using adb and put them in the right /vendor/ directory. There are plenty of examples available for other devices.
Create an .mk Makefile to copy those files to the $OUT folder during the build process and put them in the right place. Again, use other devices as a guide for what this Makefile should look like. An example filename might be BoardConfigVendor.mk
Make sure that the Makefile you just created is included from your main BoardConfig.mk via a command such as -include vendor/[vendor]/[codename]/BoardConfigVendor.mk. Again, existing devices can illustrate how this is done.
Now revise the device/ directory
Since you have a working recovery, go back and start modifying the files in the device/ folder. As always, use other similar devices as a reference.
You now have a easy means to do backups and test your builds. So start tweaking the device folder itself, and see if you get it to boot... Once you do, from there its a matter of building and supporting the various parts and peripherals, one-by-one. "

Q #1: Where all should I look on my device for the proprietary blobs, and what do they look like? Can I manually extract them out of my existing ROM and paste them into the proper folder of the new one?
Q #2: What do I modify in the device/ folder?
Q #3: What does it mean to "build and support the various parts and peripherals" Does this mean to add the necessary drivers? If so, can I get these drivers from the stock ROM?
The reason I have to ask this here is because my device has NO similar LineageOS-supported devices with the same chipset for me to refer to. My tablet has a MediaTek MT8392 chipset, and I couldn't find any supported devices with an MT8392 (or an MT6592, which is very similar). Also, there is NO code available from the manufacturer, at all. The only resource I have is a stock ROM.
Are there any other ways in which a device can be similar enough for me to use as reference?
It would be really nice if someone could provide links to articles explaining the above 3 things, or if someone has already gone through this process, share their experience.
Also, will my kernel (v3.4.67) be compatible with the latest LineageOS 16 / Android 9 or will I have to build an earlier version?
I am very new to Android development, but that doesn't mean that I can't learn!
That's a hard task for getting started. A mtk device with no twrp available. I recommend to start with low hanging fruits. Like buying an old phone with dropped lineageOS support and building an updated version.
I understand that it is quite difficult. So instead of doing a full port myself, I am now trying the method of taking an image made for a similar MTK device and transferring the device-specific files from my stock ROM, as shown in the following guide:
https://www.techubng.com/2017/09/how-to-port-lineage-os-14-nougat-rom-on-mtk.html
It says:
"From System/lib/hw: Delete all mt6572.so blobs and replace with these blobs: DOWNLOAD BLOBS
Now copy these files from stock to port:
System/lib/hwcomposer.mt65xx.so
System/lib/gralloc
System/lib/lib.audio.primary.so
Systemlib/lib.mali.soS
System/Etc
System/lib/libcameracustom.so
System/etc/firmware
System/lib/libfeatureio.so
boot/kernel
boot/unventd.rc (only if you are getting stuck at logo)
boot/Replace only camera lines under #Camera from stock boot.img init.rc to init.mt6572.rclib/libcamdrv.solib/libcamalgo.so"
But my stock ROM does not have any of the files he listed uner /system/lib! Can I ignore these files, or is there some other place where these files could be? (I checked /vendor)
Also, what about all the other files in /system/lib? Which ones are device-specific and does anything else need to be copied into the new ROM?
As for the TWRP, I have found tools like Easy Magic TWRP Installer ( https://forum.hovatek.com/thread-5162.html ) which will automatically do the porting given the boot.img and recovery.img from the stock ROM. Are these safe to use, as long as I provide the right info to the tool?
I want to use LineageOS on this tablet because the stock OS has some annoying bugs and is quite old (Android 4.4.2) considering how recent the tablet is and how much capability the tablet's hardware has. The manufacturer (IBall) has provided no updates at all.

If you haven't already, I'd recommend checking in Geekbench as there's a lot of conflicting information on the web. Usually, Samsung only puts the Exynos chip in GSM only devices sold outside the US.

Hi there, I just noticed this reply you had made and I have a question about a device that may have had Lineage support.
What I would like to do, once I have my new phone that is, is to take my current phone Motorola Edge+ (2020) and turn it into a small Lineage tablet.
However, there is one slight problem with this, and that is rhat there is currently no Lineage support for this device, but there is support for it's younger brother the Motorola Edge (2020).
Now I do know that porting is possible between devices, but I've seen a lot of guides says they should have the certain similarities such as processor and such.
However the CPU, GPU and Chipset are slightly different (Same brands though), will this pose a problem in porting?
I of course do realize that I will of course need the proprietary blobs from Motorola for this device and I believe I have found them.
Finally, I am curious if you know of any up to date guides on porting? I will of course continue researching myself, however I thought I would make an enquiry anyway.
Any help you may be able to provide would be greatly appreciated.
