Just rambling here. In order to get ICS ported to the Venue, we need compatible kernel drivers. It appears, from what I can find on the 'net, that Qualcomm isn't releasing drivers for the QSD8250 for ICS. Looking around XDA, I see the HTC Desire (GSM), also based on the '8250, has a working ICS beta found here: http://forum.xda-developers.com/showthread.php?t=1403113. This appears to use a Tiamat kernel, http://tiamat-dev.com/tiamat_bravo/. Using the AOSP 4.0.x repository, the Dell info from http://opensource.dell.com/releases/venue/v4.06/ and the Tiamat kernel, is it possible to pull together an ICS port? I wish I had more experience with this type of stuff...
Dell used the CAF 8260 GB sources when building 4xx roms, they simply backported whatever they need to from their already working 3xx codebase for whatever was needed (i assume)
CAF itself dropped support for 8x50 in their GB codebases, but the 8x60 is close enough it didnt really matter ultimately.
Much of the drivers arnt even in the kernel, they're in the android userland which is Apache and not gpl, hence the driver issue.
Which ever method you (presumedly do) to get the kernel booting under ICS doesnt really matter, but the more difficult/time-consuming methods will ultimately be more useful for porting to newer kern versions.
Don't forget the Nexus One and, IIRC, the HD2 also use the 8250
I would think this would help too: http://www.xda-developers.com/android/qualcomm-releases-adreno-2xx-gpu-binaries-for-ics/
Too bad the development work is well outside my capabilities. Maybe our Korean friends are working on it though.
Guys.!!! Dell venue n dell streak 5got same rom n environment hardware too just diffrence is venue is Hdpi n dell streak is Mdpi .so why do nt we join hands n make ics work for dell or on other hand u can take advantage of our dell streak 5 formus there r few good roms like longhorn 2.8 with Hdpi support for dell Venue and Dcs 1.1.which supports both hdpi n mdpi just need to edit build.prop n may be kernel....whish u all safe cooking ...n Friends in need friend indeed ..

Folks, I can see that Qualcomm released Adreno 200 drivers for ICS several months ago (Mar) (https://developer.qualcomm.com/mobi...phics-optimization-adreno/tools-and-resources).
Information in the above page also says that, the drivers has been tested on CAF M8960AAAAANLYA1030. As I noticed, whenever we get the source code from Code Aurora, there is also a kernel directory included. Do you think that we can start from that kernel to port ICS to Venue?

Yes we can,
But I aint that good into dev
This mobile has what it requires to run ICS
The kernel itself ultimately doesnt matter, as long as it has the right code changes merged in.
The current S5 ICS kernel's lineage is:
S5/405 (dell) -> Phoenix kernel/GB (n0p) -> Phoenix/cm7.2 (hPa) ?-> Phoenix/cm9 (hPa) -> Phoenix/AOSP (kibuuka)
Only the final step involved merging in any changes to make it work with ics, ultimately it's based mostly on the phoenix GB kernel which itself is based on the S5's 405 kernel
S5 405 = S5 408 = V 406 = V 408, they're all the same kernel (with ifdefs/configs for the S5/V).
I'd imagine getting a V kernel to boot ICS period is 85% of the work as the S5's froyo/GB kernels can directly boot V froyo/gb roms, and the reverse would likely hold.
The kernel 405/6/7/8 from Dell can be built successfully, however there are known issues such as after charging, we won't be able to boot the kernel up. I do not have a Streak, so I wonder whether those issues are fixed well in Phoenix kernel Manii? Can you show me how to get the source for the latest phoenix kernel that you're using with your Streak AOSP? Maybe I will try to build with Venue myself to see how things work!
phoenix kernel/ICS - Github
It's currently in the process of being merged back in.
You could try diffing S5 405 with V 406 and seeing what's changed in the source, they're nearly identical, but I dont expect them to be bit identical

Sounds interesting, that's exactly what I did in my custom overclocked kernel. However, I will be able to save some time by using their kernel directly. In fact, I think that 405/407 kernel is not very different from 406 since my build for 405 also ran on DV too.
I will try with their "master"/experimental14 branch kernel first (to CM 7.2.0). Thanks for your information!

Will be waste of time as only streak-specific file is board-qsd8x50_austin.c, other changes are device-independent.
Changes that essential to run ics with hwa:
kgsl3.8 - kernel-side drivers are in drivers/video/msm - direct drop in instead of one that's shipped with stock 405 kernel
include/linux/msm-kgsl.h - to make kgsl3.8 build
(not really)*streak-specific*changes to arch/arm/mach-msm/board-qsd8x50_austin.c - changes in hardware init routines needful for kgsl3.8 (updated data structures, powerrail). In short - do a diff for board-qsd8x50_austin.c between Phoenix and ics branches to find out what's changed - to be honest - changes are generic for qualcomm devices, so direct copy/paste of changes into your device's board file will do the job
Other patches that were applied to ics branch are optional (cpu governors, io schedulers, netfilter specific changes (these are only needed if you need ics' mobile data usage collecting/limits features)) or affect streak-specific drivers only (and are not ics-specific).
So, in short - update your device's board file and use ics branch - that would be enough.

Do you think I can start with the stock kernel, download the ICS tree including the kernel, then do the diff/merge between device's board file from ICS kernel to Dell kernel? After that, the original Dell kernel is patched with new stuffs for ICS, and can be used with ICS ROM?
i can also provide you with all patches made for streak against aosp source tree for shortening your mileage and instructions for a quickstart (my streak is broken at the moment, so i've suspended my development activities and got spare time for that)
please mention kernel for streak's ics is being built separately at the moment (i've got plans incorporating it in aosp build process, but it will take some time)
when i've messed with streak kernel making it ics-friendly i've realised that most of stuff can be made cross-compatible between two devices.
It's 95% the kernel, the only thing left is to turn off the rotation patch and swap out the BCM4325 for BCM4239 drivers.
On stock 3/4xx i can directly load venue roms on my S5 and only wifi is broken. (with a S5 kernel) Everything else works.

rotation is triggerable through kernel configuration menu. check.
as of wifi - is there any known-to-be-trustable list of hardware components for venue?
The V is just an S5 without the hdmi and whatever provides usb hosting.
The only other notable change is the wifi chip.
All the other sensors are compatable, and so is the modem+ril.
(I was able to get 3g working, but not wifi due to the chip being different)
I dont think anyone has done a (good quality) teardown on the V though.
Most I can offer is to pull details android gives back while it's on.
I'm guessing that's how CM7.2 was ported, since hPa didnt actually own a V,
he just took his S5 build, and flicked a few switches.
(it helped a lot that CM7.2 doesnt need any kernel changes to boot, it's just the stock 408 one with a modded ramdisk)
He only had access to a V for like a day or so.

Hi Kibuuka, that sounds good, could you please share?
One more thing I would like to ask is, the stock kernels 405/407 and 406 have issues regarding power (sometime I can see the issue that after charging, screen goes black and we can only quit that situation by removing the battery). How did you address it? (I notice that your kernel works well on my CM7, without that issue - or is just simply because it has not happened yet?)
n0p did enormous amount of work addressing sleep of death issue (which, i believe is one you refer to), so dsc kernels (opposed to stock ones) are free of this bug. Ask him for details (i wasn't involved to dsc development at the point he managed to fix it) as he's best source of information on SoD issue fix you could find
As of aosp patchset - will upload it during weekends.
For whatever it's worth, as soon as we get a working ICS level kernel, I plan on porting TWRP and CWM-touch.
Those require ICS kernels (or rather it's a great deal more difficult to make them run on GB kernels) and I cant port them until then.
I've already gotten TWRP and CWM-touch working on the S7, and plan on porting TWRP to the S10 now.
Edit: come to think of it, I actually have TWRP running on a 5xx kernel (which is HC), i'll try simply porting and seeing what happens
Hi! This is maybe a general dev question, but I'd like to get an answer anyway:
what is exactly the link between an Android release and the kernel it works upon?
I noticed most recent releases use 3.0+ Linux kernels, and others (like the DSCs) use the Phoenix Universal Kernel, which is based on a 2.6.35... So I wonder: is ICS/JB in any way dependant on "newer" kernels?
I understand the answer must be closer to "no", since the pre-alpha build also uses a fork of the PUK, but the fact that it uses a *different version* makes me wonder how much work does it take to get a kernel ready for a newer release, and most importantly... why?
Thanks a lot! Total n00b here, but eager to know more.
Newer kernel not required at least for ICS.
All GB/ICS kernels are based on this kernel (and it's a Dell's lie about using same sources for 407 release as SoD was fixed there without switching timer source):
http://opensource.dell.com/releases/streak/4.05_and_4.07/
kibuuka successfully applied kgsl/genlock patch and it's the only thing actually needed for ICS.

First, if this thread should be in general can someone move it pls.
Now to my question. I know that for example the samsung galaxy s has a similar hw as our phones and can have the new kernel, but i never saw a kernel for our phones higher than 2.6. Does anybody know if we can or cant(and why) use the new version cause it has a better security system
Some developers are working on a 3.0 kernel and there are already some threads about that

Porting kernel is not a simple task. Fxp team whom currently working on the project to bring kernel 3.x to xperia 2011 gen said it would take atleast six months, or would take forever ie it would never come to our phone.
is it really necessary?
Do we really need kernel 3.0 on our devices?
because I have read here and they say its almost same as old kernel "OR SAME AS OLD KERNEL "

Starship Kernel is being developed in conjunction with the not yet posted Starship Rom. Like I had done with the KK incarnation of the Starship Rom I am also posting the Kernel separately for anyone who may not like the Rom's Theme. Though unlikely as that may sound because I have spent much time and effort with the Kernel am posting the Kernel separately so it can be used with other Roms and not just Starship.
If you are looking for new features to play with this will not be the Kernel for you. It is designed to improve the overall experience as if it was not there. At this point and probably never you wont find over clocking or voltage controls to play with but rather just a more efficient overall experience.
Each Kernel Download section contains a link to the commit list for both the purpose of following rules about posting links to Kernel Sources as well as serving as a change log. You will find in the main branch all Linux Kernel Increment Updates are grouped into one commit. This is to easily distinguish what commits have been made as part of the Linux Kernel Increment Updates from other additions/optimizations that are not part of the Linux Version Updates. You can find descriptions of each change made as part of the Increment Updates in the staging branch. In other words the second link below the download links will give a description off the changes made in the Linux Version Updates .

AOSP/Stock (Android Version 5.1.1)
AOSP/Stock Kernel is compiles using Google's GCC 4.8 toolchain and tested tested on the Stock 5.1.1 Rom as well as AOSP compiled Rom using unmodified pure 5.1.1 Source code. The Kernel may or may not work on custom Roms based on 5.1.1 depending on what changes have been made by the Roms developer and how far the Rom has strayed from the original source code. In most cases if the Rom is AOSP based the Kernel will work but provide no guarantee as am not testing with every ROM available. If you do find a Rom the Kernel does not work with feel free to comment but please include what Kernel was used that did not work as I may be able to shed light on reasons why and provide a workaround if possible. Most of incompatibility will find that the Kernel is not the issue rather what is included inside the boot.img like Ramdisk iinit.rc files that set permissions and create the Rom file-system.

CM-12.1
CM-12.1 Kernels may be updated more frequently without posting a new date so don’t be surprised to see multiple release number increments. In most cases there has been no change in the Kernel itself but update frequently as development is fast moving. Because of this some of the files that get packaged into the boot.img along with the Kernel may change and cause issues. Because of this will update as frequently as I can to insure everything packaged into the boot.img is up to date.

I am not responsible for any effect using the downloads from this forum my have on any device and you download and use at your own risk.
Just decided to include the CM-11 Kernel for anyone who may be using CM-11. Is a nice Kernel and gave me an extra hour or two battery so recompiling with a few new commits I have been using in both CM-12 & AOSP. Will post in a few. Checking nothing else may have changed on the CM side with the rest of the boot.img and will post in a bit.
I will try out the AOSP kernel tonight or tomorrow, we are under blizzard conditions right now and can't mess with phone because of work (boss & I texting back and fourth)
Thanks for your work

Sorry about this then but have uploaded an update. I had intended on holding off until reaching Linux version 3.4.40 as it is the version I had left off with for Kit-Kat and have just been modifying each version increment patch from the Kit-Kat 3.4 Kernel for Lollipop. Anyhow last night before bed had used my Bluetooth Headset with the current version and sounded like I had gone out and bought a brand new higher end set so decided to post the update now. Found in the past Android can have a completely different experience when it comes to different BT devices like for example the same headset had become completely unusable on my N7 with constant skips and pauses on 4.4.4 after working beautifully on 4.4.3 so hope others can hear the same boost in overall audio quality including BT headsets.
Updated Kernels with a few new optimizations and 3.4.36 version update
Ok will try it

Looks to be up and running. Can try direct links though.
updated so links are no longer current.
Well it feels like with all the side track projects been talking Starship L long enogh maybe some of those who have sent PM's asking about the lollipop update are starting to become doubters so decided to post up a few screen shots. Was going to finish a few things then go over the theme image by image and color by color but think instead after finishing up a few things will post and then start going over each apk over again for touching up, fixing and adding missed optimizations including Kernel updating along the way. Once again not for everyone so haters can hate and I just keep doing it because its what I like doing.
Made new boot.img for Stock / AOSP 5.1.0 as old image used in 5.0 - 5.0.2 caused boot loops.

Honestly have been meaning but have not tried MultiROM. Looked over at the thread and see allot of mention about the boot.img and modifications. If I had to guess with the limited knowledge I have would say if not working is not so much the Kernel but the boot.img in the same way that both the Stock / AOSP zips posted are the same exact Kernel inside but changes made to files like the init.rc inside the 5.1.0 boot.img that creates the file system and sets permissions among a score of other things caused 5.1.0 from booting properly after updating and flashing the boot.img. As developers we use the name Kernel but there is much more inside than the actual Kernel. In some cases can be more than a dozen other scripts and other files inside. Will need to try and learn a bit about MultiROM. Out of curiosity was it Stock or CM giving you issues?
Little more reading and looks like not everyone including CM has updated to include new bootloader version checks to include new bootloader from the 5..1.0 update. So for example I needed to change the bootloader version in CM source or nightly builds will not flash in TWRP without errors.
Maybe an update on this if flashing CM version, seems latest CM12 is receiving errors flashing with some recovery versions and must be installed via adb / fastboot. Article was not specific on the reason but may be the cause.
Added updates to version 3.4.42 for both 5.1.0 and under. The 5.0.2 zip should work for all stock and AOSP Roms from 5.0 - 5.0.2. Because of changes in 5.1.0 boot.img 5.1.0 will not boot when used with a lower Android Version.
Slightly disappointed as today had planned on posting full Starship Rom but now updating for 5.1.0 so maybe another week maybe two
So any details on what this kernel does? Or is our just close to stock?
CM12 Kernel is on hold until 5.1.0 version update. No reason testing anything new until can confirm everything will still work next week. Also figures the same week I had planned on posting the full Starship Rom the 5.1.0 update hit so now am back in testing optimizing phase for a bit longer.
3.30.2015 update
Linux version has been updated to version 3.4.55
All MR1 changes added to the 5.1.0 AOSP Kernel have been merged into the Kernel
https://github.com/Starship-Android...mmit/8ed8c47ff15f1c5fdd6707f7a52f76110aed6cbf
4.6.2015 update
Not much on the AOSP/Stock side. Wanted to post a cm12 update so decided to post the AOSP/Stock kernel earlier than I would normally with a few Linux version update patches. With that said updating the Kernel only takes a minute or so and not like asking to flash a new Rom. Kernels are easy and these days faster to flash than g-apps. Also used the 5.1.0_r3 source to compile the boot image for 5.1 instead of 5.1.0_r1 source I had been using. Honestly though did not check if anything changed that is packed into the boot.img along with the Kernel between r1 & r3 so may or may not make any difference what so ever.
Forgot, marked the cm-12.1 kernel as beta just because cm-12.1 is pretty much beta. Otherwise the Starship 12.1 Kernel is the Starship CM12 Kernel merged with the Cyanogen 12.1 Kernel . Not that the two had been far apart to start but the 12.1 CM Kernel merged into the Starship cm12 kernel clean as a whistle with 0 conflicts. Was pretty happy about that so going foreword will just be working on the 12.1 Kernel with the Starship cm-12 Kernel soon going the way of the 5.0 - 5.0.2 Stock/AOSP Starship Kernels.
Now finally since the actual Starship Rom I have been working on since the darn preview release ending as mostly caf based with CM-12.1 coming together can start updating from 5.0.2 into 5.1 as had just finished going over the first draft and was about to post when the 5.1 update hit. Otherwise wanted to post the first draft and then go over the entire Rom a second time looking over the theme images, features and optimizations with a magnifying glass.
Have updated both Stock / AOSP and cm-12.1 Kernels up to Linux 3.4.65 with a few other additions and weeding. Has and been running pretty sweet on both so far.
Stock / AOSP 3.4.65 Kernel boot.img has been compiled using the 5.1.1 AOSP Source and tested on both 5.1.0 & 5.1.1 with no issue and as mentioned above running pretty sweet.

Hi, this is my first post on xda, but i was reading it about 4 years and now i have unusuall question:
I have phone - samsung callisto (GT-I5510) with cyanogenmod 10.2 rom (android 4.3.1), and kernel sources are available for it, but only below 2.6.35.7 since phone is ancient. This is "latest" and probably "fastest" android phone with qwerty keyboard (not including this unrootable new blackberrys), so i think that it would be nice idea to deploy lightweight kali linux nethunter installation for hacking purpouses. I had some problems with oficial installer, and i had to modify it to allow install on device with such small /system partition, but the problem is that chrooting to Kali Roling is not working, becouse minimal kernel version needed is 3.2.*.*
Question is: Can i somehow "update" kernel sources of this device, so i can build 3.2.*.* kernel? I have much free time and even more determination to do this.
