Kernel development - Galaxy Tab General

Hi All (esp richardtrip, koxudaxi, alterbridge, humberos and other kernel developers)
Does it make sense to have the kernel sources in a git repository so that the work done by all the developers can easily be shared. I ask this because right now I am at a loss as to which kernel is considered stable and which are experimental.
tovarish

Ive tried them all, and they are all stable.

Thats great, could I request the other kernel developers to use richardtrip's github for their kernel versions. I think the community can greatly benefit from that.

[ROM: DEV] CM7.2 .35 kernel

Ok, this is just something I have been playing with and thought I would share.
It is CyanogenMod 7.2, as close to stock as I can make it. I have taken a lot from Ezet and some stuff from Forumber.
This is not source based as I do not have a grunty enough system to build CyanogenMod from source.
Most importantly, I have started on a new kernel based on the TomGiordano source here:
https://github.com/TomGiordano/kernel_huawei
My Kernel Source:
https://github.com/PaulMilbank/kernel_huawei/tree/cm7-u8800-35
Will upload my source once I can sort out the sources on my computer. I am doing some mods on Aurora kernel too which I will release at some point.
After a few false starts, I compiled the source with their cyanogenmod_u8800_defconfig and it works pretty well for CM7.2.
I fixed atmel vibration using DZOs aurora commits as a guide.
Probably most broken stuff is defconfig related.
Bugs:
Keypad LED's do not work
Autobrightness does not work
Light sensors do not work- probably the cause of the above problems.
Camera force closes
You tell me
Working:
Wifi works
RIL works
Screen/video drivers work well, screen does not suffer annoying no wakeup for me like other kernels.
Atmel Virtual Key vibration works
You tell me
Get It Here:
http://www.mediafire.com/?b2dc7kdmixvas18
I will try and fix all these bugs, but I would be keen for some help too. I don't have time to be a full time dev.
As always, I am not responsible for any bricks, fires or nuclear wars that come about from installing this rom.
Please, please backup with CWM before flashing this.

This is just to see if I can get people interested in development. I will try document as much as possible what I do and see if we can get some people interested in building a kernel and getting a really good gingerbread cyanogenmod build out. If this goes nowhere, I will just focus on Aurora kernel and ICS. There are a few things I would like to try and include in Aurora to add some features.
We need good 2.6.35 source and this is a good source with a few small bugs, probably due to the config not being completely right. Hopefully they are minor and easily fixed. We have a lot of kernel development going on around the place and we can learn from commits to make a really good build hopefully.
Will try their 7x30_defconfig to make a kernel for my B528 rom too and see what works.
If you replace the boot.img in this rom with the boot.img in Forumber's latest cm7.2 build, it sould all work and give a 2.6.35 experience close to Ezet's 2.6.32 build. It will likely not be as stable because LEWA kernel on my phone at least, is crap.

Thanks, this will likely take a while longer than I thought it would as I am having trouble getting my sources synced locally and on github. If we can pull together all the sources into a kick ass kernel, we should have a really good CM7.2, I would like a rom with built in tethering too. It will just take some time. Running through DZOs excellent repo with a readymade .config and then making small changes is a lot easier than having to make it all up as we go and sort out sources and configs. Maybe I should not have been so cocky at the start!

But you could compile kernel?
Compiling and downloading kernel is much smaller and faster. Also their are a lot of comments and files to follow.
Compiling cyanogenmod from source is a huge download and would take forever to compile on my computer. Plus nobody documents the process well and it us specialized to the phone.
Maybe if I can get a good kernel going, others can build cyanogenmod sources for .35 kernel. It all just takes time.

Guess it has something to with the "new" Adreno drivers. Might do some benchmarking later with the older ones. I haven't really experienced lagging myself though. it's kinda the same as w/ .32 based CM7 (especially when using ADWLauncher)

[REQUEST] N8000 Kernel Source

I am about to build a kernel for N8000. But my problem is I can not download from samsung open source site (Very Slow Connection).
Can someone please mirror the update7(MD1) for me on a fast server like dev-host, android file host, mediafire or etc...?
Here's the Samsung open source site:
http://opensource.samsung.com/reception/receptionSub.do?method=search&searchValue=GT-N8000
Thanks in advance.
You may use my GitHub repository, which has a branch "merge-to-ss-jb" that is just the vanilla Samsung kernel, backed by the complete Linux tree.
Also, if you're interested in a complete, up-to-date tree (and what I'm running on my own GNote) you may browse my "kernel-forward" branch.

Thanks.
I have two questions if you don't mind.
1. Merge-to-ss-jb is the latest source (MD1)? Is it a good to go for a kernel to be based upon?
2. Is it alright with you that I base my kernel on your own kernel?
I appreciate it if you can help me with some kernel stuff as I am new to this.

Yeah, it's essentially the official Linux kernel source up to version 3.0.31, overlaid with a cleaned-up version of the 1st Samsung JB kernel release, then each subsequent Samsung Open-Source Release (latest is "#7") is overlaid on top of that. If you build the HEAD of that branch, you'll have a vanilla Samsung kernel as of XXMCD1.

Of course! The entire Linux kernel is built upon Public collaboration; we all share from each other. My kernel has a few selected bits here and there from diverse places like CyanogenMod, Francisco Franco, Xstacy, the upstream kernel, Qualcomm, NVidia ...
I used to post my built kernel up in the ROM threads I used to use on my GNote, but someone complained and I don't really feel like being bothered with my own thread (don't have time for the inevitable newbie SPAM) so until if/when I do go "public" with it, the "kernel-forward" branch on GitHub is the best place to get what I'm running now.

Heard that the published sources have different wi-fi drivers than preinstalled stock kernel.
This is the main reason of allshare cast not working with custom kernels (on the contrary, some s3 custom kernels DO SUPPORT allshare cast), even if status=official and flash counter=0.
Anyone can confirm?
Anyone has the proper ones or know which one (i.e. from a different samsung device) to use?

[KERNEL] Bacon Official Kernel source

The kernel has been open sourced, by CM, as any OEM should do when device hits retail. That means a great step for us, ROM developers. We may discuss findings for reference on future development here.
Link to source code: https://github.com/CyanogenMod/android_kernel_oneplus_msm8974
By the way, it's not only useful for the OnePlus One, seems that it's interesting for Find 7 as they borrow some code from it, worthy to read.
Oh Gr8 news ! Hope we could get custom kernel on OPO soon

Mind putting together the flashable zip of the stock kernel so that users who go custom kernel flashing (Franco for now) can fall back to the stock kernel?

Gamma control is out:
0f98e789af8c12ce3687cbe4515b429aa1e031a3 video: mdss: Add predefined gamma selection
I'm a bit confused.
So far, I know of two kernel sources: This one and AOSP-compatible sources released by OnePlus directly (OnePlusTech on github, can't post links at my postcount).
However, there are already custom kernels that claim to only work with CM11S, and others that claim to only work with CM11. I assume the latter are based on this source. So what's the current (official) branch for CM11S?

So kernels that don't work with the stock ROM are just based on a newer revision of the kernel in CM's repo, and older revisions in there would boot CM11S just fine?

Lollipop Kernel

Hi people,
With the recent announcement of @pedestre (creator of apolo kernel) that the development of apolo kernel comes to an end and Gustavo kernel does not be updated since a long time, we have no costum kernel for the many 5.1.1 roms that are coming to our phones....
Many people uses bln, cpu and gpu voltages control etc.
I want to ask someone with skils who can compile latest cm kernel, witch i think that will be compatible with all newest 5.1.1 roms, with basiclly feautures like bln and others... and if its possible, keep it update with lates cm realises....
Thanks, i hope some dev can help us

I can develop if @pedestre can give me the permissions to let me continue Apolo. Although, I'll do that and all the other ROMs' building stuff after 6th of June.

I'm sure he would give you persmission to do that.
Right now I'm cloning my repo of dorimanx kernel. Have made a few changes like chhapil (except no uber tc yet). I'll see if I can release something next week (however will be very busy with exams). I'm still very new at building kernels so expect a few quirks with the kernel.

I vote for gustavo's kernel since last version of it was just everything i needed. Miss it's colour control very much
I would love to see a TWRP kernel, as I use the file manager to delete unwanted system files on rom updates.
I do think it has a more friendly UI too.
We need 2 type of kernel. One like gustavo_s' and other is like apolo.
One for full control
And other is daily usage and more stable
Or maybe one based on apolo with CPU and GPU OC

I'm pretty sure there not much work needed to get Gustavo's kernel working on newer lollipop builds. Right now, I've made changes to io schedulers, TCP algorithm, supersu. Still have no clue how to get build started, at least there's progress. Change of mind. Will be busy with exams.

I Have tested on mine and it's blazing fast.I Just wanted make sure it's the kernel and not the mods that i applied to the ROM ^^
The perform with your kernel is the same has cm 12.1 stock kernel and when i install your kernel my wifi dont work im using moke open source rom up to date with the cyanogenmod sources and you can add some cpu governors, faux sound control, simple gpu algorithm.

I think it doesn't "reserve" being a project because this is just an experiment i made with a toolchain,also i'm not going to add any feature to it anytime soon.
yes it's working fine and make things better.
