[HUAWEI U8100/U8110/U8120] Froyo Kernel Development / Porting (Your help needed!)

Many people want to run a working froyo on their devices.
This won't be possible in a clean way without compiling a new kernel.
To archive this goal, we need to merge the Huawei specific device drivers (which are for 2.6.29) into a new kernel tree, the 2.6.32.9 one (or even 2.6.35 but 2.6.32.9 comes first since it is stable and thus important to us).
I did some research and preliminary work which I will explain here:
- The base kernel Huawei started with is available here (gitweb) - also check their wiki.
- Huawei started with the Q8650BSDCANLYA324020 tag on the donut_glazed branch (see instructions at the end of the post)
- Huawei has written it's own board driver (note they have used a Q8650 kernel release not a MSM7x25 one, most likely because this board driver is a little older and was not available for the version they wanted)
- After they were finished writing their drivers they released the kernel source (as you can download it from Huawei)
I have checked out the Q8650BSDCANLYA324020 base kernel version and diffed it against the kernel release of Huawei, generated a patch file (and stripped out the DOS linebreaks wtf) which can be applied to the base kernel.
Applying this patch to a more recent kernel (2.6.32.9) is not possible without merging the code into the new kernel tree (and since I'm not a programmer I can't do it - this is were your help is needed).
The other question is in which kernel tree we can port the patch I have extracted. I think we can use Q8650BSDCANLYA504005 on the froyo_almond branch since Huawei used an older version of it. Merging it into the AOSP msm-2.6.32.9 tree may be possible too (but the code aurora msm kernel is an improved AOSP version, so I guess we want that one).
My patch (and some non-pulse-mini fixup patch) alongside with a freshly extracted and fixed .config for the U8120 can be found at http://nico.core.ws/misc/huawei_kernel_u8100_8110_8120/
To port the source you need to checkout the original source (Q8650BSDCANLYA324020), create a new branch in which you apply the Huawei patch, then checkout the froyo kernel (Q8650BSDCANLYA504005) and merge your branch containing the changes from the patch into it.
Another way may be porting the froyo kernel tree back to the eclair one with Huawei patches.
Please post any results/questions/etc. here!
If we should get this working we can also enable the GPU driver (Adreno 200) as requested by many people (and much more (CyanogenMOD anyone? )).
Appendix:
Instructions on how to get the original source:
$ git clone git://codeaurora.org/kernel/msm.git
$ git checkout Q8650BSDCANLYA324020
Instructions on how to apply the patch (assuming "msm" is the kernel tree):
$ cp diff_kernel_msm_aurora_Q8650BSDCANLYA324020.diff msm/
$ cd msm/
$ patch -p1 < diff_kernel_msm_aurora_Q8650BSDCANLYA324020.diff
If you are compiling for U8100 or U8120 phones, you need to apply another
patch which fixes sensors (otherwise your phone won't be able to read battery
level and stuff):
$ cp needed_fixes_for_non_u8110_devices.diff msm/
$ cd msm/
$ patch -p1 < needed_fixes_for_non_u8110_devices.diff
Note that the above instructions will get you nothing new, only the kernel already running on your device.
This thread is about porting the Huawei patch to a froyo kernel.

Very nice! Thank you for this topic!
I hope this will be successfull

Are the Atheros sources included aswell?

To be honest, I don't know. They should be in there though (maybe under a more generic driver name or integrated in the board driver) otherwise Huawei would have violated the GPL.

The problems with the fixes:
wifi
They got almost wifi working in other post
radio
FM radio too with an 3rd party app
dpad
dpad crash in this post too 2 pages back just disable this
screen calibration
calibration fix can meaby be fixed with HTC calibrate??(its an calibration app)
sound
I solve the sound problem with my phone is to replace the libaudio.so from 2.1rom,maybe you can try.\

Basically this is the complete kernel source for froyo without Huawei patches (it's the wrong tag too).
When we have ported the drivers we easily can enable that driver.

Thats the source for the U8150, not the ones we want. The only thing which may help us at a future point in there is the kernel config.

If you compile a kernel right now you'd get a kernel that won't read the batterylevel and the magnetic compass won't work so we need to make a few adjustments.

So nothing new here.

So what can we do to help?
Is there a way to chat in XDA?

Any news on this?

Someone with git/kernel/c knowledge need to port the patch.

You need some elemental knowledge in C and then simply cut and paste the text in the files.
However, I think that it is more important to be able to compile from source and install the existing Huawei Linux kernel for the U8120. That is, can we compile from source all the code for Android 2.1-update1 and install on the U8120?
It might be good to try to get CyanogenMod on the U8120 for the kernel version that Huawei provides. Then, we can cut down the 1.5MB patch into smaller parts, and even try to get the drivers included in the Linux kernel.
I have not idea how to compile Android 2.1-update1 and get the plain old android source on the phone. I am willing to invest the CPU clocks to compile it, though.

Can we just replace the normal kernel in the command list for the new kernel so you apply patch in the new kernel(u8150)froyo kernel?

I have had contact with benee a kernel developer for the htc desire. He is willing to help but he needs a device so he can test kernels he build. It is not possible to build kernels without a device because this is a huge project without a good base.
Maybe we can setup a fund raiser to get him a device?

Samsung Source code KB5 version

As per my request Samsung updated the source code to the version we have currently on our phones.
h ttp://opensource.samsung.com/reception/reception_main.do?method=downLoad&attach_id=1036
What else do we need now to get cyanogen on here? lol

Get CWM working!

Sorry for being the outdated, uneducated, tool but what exactly does this mean?

I'll be honest I'm not sure... I'm not a programmer for android but I do know someone mentioned that we don't have it. So I went ahead and emailed Samsung and they actually responded. So thought I would throw it out there.

it's for devs and builders. the kernel tar is labeled kb7, actually. krylon probably had this already but still.... good lookin' out man.

So does the source code include the kernel? I want to help get the ball rolling but I need to know whats missing...

kernal is included yes

So are we trying to figure out how to "unfreeze" it?

Warning -- as Krylon points out, this appears to contain KB7 source and the device appears to be running KB5

HOW TO BUILD KERNEL
1. Visit http://www.codesourcery.com/, download and install Sourcery G++ Lite 2009q3-68 toolchain for ARM EABI.
2. Extract kernel source and move into the top directory.
3. Execute 'make vibrantplus_rev00_defconfig'.
4. Execute 'make' or 'make -j<n>' where '<n>' is the number of multiple jobs to be invoked simultaneously.

About Jelly Bean i don't know, but it must help to tune cpu governor (in default cpu works on deep sleep, 166 and 1001, but don't use 250 and 500), may be it help to solve the problems with proximity and light sensors... etc.
In theory you can take JB original sourses from Google and mediatek sources for ICS, and may be you can run JB from other device (for example last firmware from JY G2 MT6575)... But so far no one has yet tried to do it... Sorry for my English

Ok guys!i would appreciate it if you could solve the problem with governor!(ondemand mode 166,250,500,1000)!it works only 500-1000!A new custom rom maybe?thaks!

Adding Swap support to JB 4.1 kernel

Hi developers
I want add swap support to my MTK android 4.1 kernel 2.6.35 thanks to members of the forum to tell me how
Compiling the kernel from source adding the line CONFIG_SWAP=y in config file. and them swaon script (am I right?)
I'm following ubuntu terminal tutorials for it.
But What should I do if I dont want use a open source kernel code??
I mean if I wanna use the same kernel from the phone, IS there
any way to open and modify the existing kernel??
I read its can be dangerous for a MTK use another kernel, and I found a mtk6575 open source kernel but it isn't specific to my phone
so, I dont wanna use another!
I hope I can use my original kernel and add it swap support
by the way I have 2 diferents backup from my phone, If I can use it wich one?
