Complete Kernel Source Code is essential for building rom from scratch
what lenovo did it give us incomplete Code missing the important files and directories and hide the essential part
Lenovo should release kernel source in full, so we can look after our self
Kernel development doesn't take place unless we get the device's schematics and its corresponding defconfig.
Lenovo has hidden the caf tag inside the firmware. there is matching qcom caf kernel tag for the same chipset. But without the schematics of the device, we couldn't proceed in developing
until now the official source is incomplete
but some developers trying to fill the gaps from similar devices you can find these builds on github
here is the last source kernel from lenovo and github

i can't confirm any thing now ,
but i think the coming days we will make progress to solve sim bug completely on CM12.1
missing things
Hi,
I find following things missing from stock kernel
1. whole kernel directory all together
2. Def-config (altough i managed to extract it from boot.img)
Do you what are other things that are missing?
I'm able to compile the kernel with some fixes from cm kernel, but now able to generate the dtb file. Any help will be appreciated.
Thanks

good job chhapil
i gave links to kernel source from github it should be completed
you will find also at github the source for cynogenmod 12.1 if you want compile it
Here is the latest update from my side.
I'm able to create zimage from kernel, dtb from source. But the kernel fails to boot.
If I flash my kernel the phone restarts with blank screen and it mounts all the partitions when connected to pc.
I'm not very sure what's going wrong.

kernel boot issue
Hi,
Here is the issue i'm facing.
I created a new image from the KK stock kernel + the missing parts , repacked it the boot.img from the stock rom.
When i do
fastboot boot new-boot.img
the phone reboots and mounts the system partition and couple of other internal partitions with no display.
Do you know these symptoms?
Any Idea what could be going wrong here?
On the other note,
the LP source code compile good without any issues at all, but I'm using stock KK so there is NO room for to make tries with it.

Will be updated soon
Issues:
Settings app: closed automatically when activate Bluetooth.
Kernel information: still appear on 3.0.101, i guess modules of MoshKernel should be updated too.
Android rebooting each 10/15 minutes.
Wifi: not working.
Code:
[*]22/04/2015:
-initial build.
-I will make zImage and use as prebuilt kernel in my roms after add arch-capri drivers.

After done some google search about to find similar devices to our phone and some guys on Whatsapp group give me some useful information about Samsung Galaxy S Duos 2 that device share same broadcom chipshet but the kernel is more updated (3.4.5), so I decide to port this version to our phone Samsung Galaxy S2.
I start some tests witnout arch-capri drivers in kernel/samsung/3.4/arch/arm just to see if Android boot or not, the result was really fantastic so from today we can port 3.4 kernel without any problems.

the differences are:
-roms will be more stable.
-kernel new and updated instead of old stock and slow 3.0.101.
-antutu test result about 13000 points with some fixes may get better result.
-fast booting.
-this version could be useful for android 6 when will out.

So this one is really down? Hey, man, we need you, continue your work
why me? the best succeed I got is integrate part of capri's kernel archecture into 3.4 and entire code should be readpted to work on our phone. in case of even ported, I will not release the source coz I will not do the homeworks of others
3.1.2 Kernel
-update patch like 3.0.31 -> 3.0.32 is adapted as well.
-now im apply the patch to update the code see ya.
3.1.2 in progress
I have a question dear @CoolDevelopment I manage to update the kernel of this phone from 3.0.101 to 3.1.2 using the patch of kernel.org's website.
here my questions:
-if got failed patch, should skip them in case can't found it code?
-I saw there are a lot of detected commit that already patched, should be skipped too and apply only the new code?
-is enough just downloading 3.1.2.patch and use patch -p1 method or should download kernel source too.
https://www.kernel.org/pub/linux/kernel/v3.x/
now I'm compiling a zImage seems no errors for now, if boot I will continue the port :good:
thanks in advance

I hope you don't have just changed the version numbers...
no i didn't, here my new branch

Compilation is work fine, now i will try to compile with make -j4 bootimage to get the modules and use them on nebula's flashable.
Hi, I'm currently trying to build AOSP for our device from source however I cannot figure out how to add device support, I've followed so many guides on editing the local_manifests.XML but I can't seem to get it to work.
Can any of our devs explain to me how to build AOSP with the addition of our device support? I'm not entirely worried about kernel ATM as our source was released so I will build that.
I just can't for the life of me add device support properly.. Could anyone link me to a guide or some other stuff to read? Google is very unhelpful when googling Linux related issues.
Edit - to clear up any confusion bottom line as of right now I basically need to know how to implement the device tree we already do have (several github links, mainly cm based) into my AOSP source.
Would I just technically copy the files into Google's already created device/vendor/ folders?
https://source.android.com/source/add-device.html using this link as reference. May be very bland.

Hello. I have a plan to build CM13 for LG G-Pro 2 but I can't do it alone, I mod device tree from LG G2 D800 because I think it have the same harware(different configs kernel), if it can run, it'll have some bug, if anyone have more time can help me fix bug. I'll share source for anyone can build it.
here is source of my project
caution: I'll use same kernel of LG G2 here , copy b1-skt-perf_defconfig and insert to LG G2 kernel kernel/lge/msm8974/arch/arm/configs
then build it and fix bug.
I can't take vendor of my device, then I use vendor of D800, if anyone can take it, replace vendor/lge/f350s/proprietary I think it better.
configs kernel here
If anyone can build twrp, please give me source
update kernel here

edit b1-skt-perf_defconfig :laugh:
it's nice to see someone trying to build cyanogenmod,I have no experience about building ROMs but I can test builds.
G pro 2 uses the same front camera sensor as the G3, IMX208, G2 uses IMX 132. Maybe that info can help.
I have been waiting for it!
Its glad to see the project is building!!
I'm build done but when I flash and reboot. it say err "boot certification verify...." and black screen but have light.

about the errors that I had, I am more than glad to share them (I have a simple text file and write reminders there, to remember them and not "reinvent the wheel" every time)
For this one, PACROM, I think the only error was 'unsupported relloc 43', the cure is:
cp /usr/bin/ld.gold prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6/x86_64-linux/bin/ld
(for a long time, i thought the cure was WITHOUT_HOST_CLANG=true)
the manifest is a mess but here it is...i also have created a file in vendor/pac/products and added cm.mk in device/sony/eagle...built it with "build-pac.sh eagle"

Sometimes you have to make changes to the framework files of the ROM and to the device tree
Hello guys,
This is a project I was working on for a kernel for our SGY.
I made it with a few things in mind:
>Improve it's performance
>Be universally compatible (after I nearly given up on trying to get a snappier CM11 and after the need for a snappier SGY, I decided to go back to GB. However, BML is terrible, and it is annoying to come back to. I decided to build a MTD kernel for Gingerbread then, and it works!)
>Experiment and upgrade as much as I can (thanks @robcore!!!!)
But since I lost my device, I cannot continue developing it. I am then releasing the source code (sorry, no flashable stuff, I deleted it long ago ) for any of you to continue(?) my work if your heart so desires.
If I ever get myself another SGY (or another BCM21553 device), I will gladly continue development (and support whoever does it too), but before I lose all my data and the kernel code alongside it, I am making it available.
This kernel features:
-OC up to 1040MHz (It's questionable even today if the bcm21553 OCs really work, but I tried hacking a way that works very similarly to MarocOS's one, maybe even better. Be warned though, the source around it is messy)
-GPU hacks for performance (Again, even I don't know if they do work, probably the values are just there to be seen, I'm not sure. I do know though that increasing the CPU speed will much likely increase the speed of V3D too)
-DVFS disabled (I found out DVFS is mostly the culpirit in the "832MHz crisis" where the kernel would forcefully scale itself to 832MHz, so I eliminated any reference to it in kernel code. Apparently DVFS on the processor is only available under the bcm21553 governor, but it is present on the other drivers as well. The idea for disabling DVFS came from my friend @robcore)
-A few additional governors and a buggy interactive governor (which is the default xd)
-MTD support for Gingerbread (Thanks Samsung Epic 4G! Although it only works on TouchWiz (I tried it with SL v2 and v2.1 and it works, but under NougatME(CM7) I got no success and loads of segfaults), it works ALMOST perfectly. See bugs for details )
-Some scraped source code from Samsung's FSR I found on the internet (barely compilable, though)
Bugs:
>Gingerbread version:
-IMEI won't appear in the Status screen, I also faced problems with non-working radio for calls. Data works just fine, but calling and receiving calls is unavailable. I believe it is EFS-related. My suggestion is backing up the EFS partition's file structure, then converting it to MTD, then restoring the backup.
-TWRP will crash and panic when exiting, a workaround is force rebooting
>ICS version:
-TWRP will crash and panic when exiting (I believe fixing it here will fix the bug above too)
>KitKat version:
-Flashing images fail randomly, you may also be unable to reboot normally if you do so. I tried addressing this but I couldn't get anywhere.

Thanks to:
@robcore - his development on the Snapdragon S4 breathes life on my dev soul!
@zman0900 - I saw his thread on an MTD TW kernel for the Samsung Epic 4G, which led me to believe MTD on GB is possible.
nice kernel
It sound nice. I'm a newbie developer, I'm building a kernel to fix audio bug on cm9, hope it work. And thank you for the source

Have you gathered enough info on it? I would like to fix it too, but I couldn't get any info on whether if the audio bug is a kernel-side issue or an OS -side issue.
Best of luck for you
Building and fixing

I don't sure so I decided to build a kernel from your source and another cm9 version from Mohamad.Afaneh's source and I'll merge the audio on both of them for the best think to fix the bug.Thank you .
Link for kernel?

Compile one for yourself,man. It only takes like 15-25 mins

He wrote a script already, just add your toolchain and run the script. There's a guide in the readme

Ok. The watson-kernel-bcm21553-src is used with other files?
Because i want to make cm9 mohhamad afaneh optimized version

To make it, you have to sync the cm9 source code then add the files from his github to your localmanifest. This thing is not in anyway related to that except the MTD. This one is a kernel-compile only source
Oh man, i give up. I can't build a kernel from source, but i can modify a kernel.
Can someone give me the zimage for ics Please....

zlimage? We don't have that here, we only have boot.img for kernel

Or you can give me the extracted boot.img files. (ICS/KK)
I will rebuild it using dsixda's android kitchen.

Sorry but I can't because I'm bored of making ROMs so I switched back to Windows. I'm planning on making a ROM, I'll compile the kernel for you once I get linux installed

Sorry but I can't since my sgy is dead for a long time ago. I'll try to make one if I can find one. I've heard that there are some places that sell sgy for about 5 bucks, i'll find one ì possible
Be fast bro!!
