Why are we still using a 2.6 kernel? Isn't ICS supposed to be a 3.x kernel? What are the benefits that we are missing out on by not having a 3.x kernel? Is there any difference in performance or features? I have no idea about any of this. I am hoping that someone can shed a little light on the subject for me.

2.6.40 is 3.0
The prime is running 2.6.39 and 2.6.40 was the version that became Linux 3.0. We're just before 3.0. The big issue is that Android develops outside the Linux tree so they have to port Linux changes in to Android. That takes a while. The good news is that Android was merged in to the Linux source tree recently so they should track more closely in the future.

Flagship nexus/4.0.1 already ran 3.0.8, so that's Nvidia fault.
Edit: I stand corrected, thanks DiamondBack.

No it's nVidia's fault. The standard Tegra3 kernel is 2.6.39.
But anyway, we are not missing much at all.
As Gary posted Nvidia Google and Asus has a meeting this week. So at least there is hope they start pushing things forward soon It could very well be that the "gaming issues" discussed in another thread are related to the kernel as well^^ Not that i have an idea what exactly the kernel is doing but its the only explanation i could see with my limited knowledge
.21 is pretty great so far, but we're not quite there yet.
@OP ...good point.

So, what are the benefits and/or drawbacks of a 3.x kernel? Is there much difference?

Apache incorporated the 3.1 kernel in the TF201 CM9 nightlys about 2 weeks ago (sorry - I realize you probably know this ). A lot of people were complaining about it since they were having problems, and he reverted to 2.6. I was pretty impressed with 3.1 - my wifi would occasionally drop off but the power consumption was a load better than the 2.6 kernel.
If anyone is unlocked and interested in how 3.1 runs on TF201, search back through the CM9 thread in the Development section. I am pretty sure that the 05/10 nightly uses the 3.1 kernel...

Unfortunately I just landed on Gummy ROM. So far its been a real treat on my prime. I might check out CM9 just for the kernel and yeah I bet battery life is much better!

Only the 3.2 and 3.3 kernels have made substantial ARM and Android related changes. 3.0 and 3.1 are effectively still 2.6.39 when it comes to features.

Gummy is sweet - I really liked it before I went back to my personal favorite - Eos Cornerstone nightlys. I used CM9 for several weeks but moved away from it when Gummy appeared. I will go back to it at some point - they're definitely pushing things in terms of development like using the 3.x kernel, getting the dongle working on a non-stock rom etc
Actually 3.x kernel has no essential features that must be implemented to Prime. I can count some I treat really useful: memory management changes, driver for Tegra AES hardware (will affect SSL and VPN performance, I think), maybe some changes in networking. Nothing we can't live without
Am I right?
Other Device with Android ICS and kernel 3+, work more smoother then with kernel 2,6.
And Google add Kernel 3 to Galaxy Nexus. If there is no more changes? why they do it?
But what about rumors. Asus Doing Kernel 3+ for Prime or We never get it?
Honestly I don't need more smoothness to my Prime and I even didn't overclock the processor yet.
Let Google experiment with Nexus, I need more stable software. There's enough bugs in the Prime, I don't need any more. Of course I'll try custom ROM with the new kernel, but only if it bring something really useful.
I saw a small video regarding one of the developers talking about Linaro....will it be used on the S3. Merged in to CM9 builds perhaps when they arrive on the S3...?

i was wondering almost the same thing: will it allow the devs to develop smaller code? as speed is not an issue...
Looks interesting

I want to try to compile it with Linaro but there's some porting to the code to be done, right now it's not working on the newer toolchains.
I thought it was more than just the kernel, like the aosp libs source were modified to be able to be built with Linaro. Then those changes get merged into CM, which can then be built with Linaro, and hopefully we all get to use it

The best of luck Andrei. Really hope you get It to work.
If you do get it working, you will have an immensely popular and cutting edge kernel.

Is there a CM10 AOKP kernel with OC support and additional governors for our Note out there yet? I know AT&T and T-Mo SGS2 and SGS3 have those kernels already...
No

Give it time oc will come after stability, first stableness, then oc. But honestly why oc, my GNote is fast enough, i can't keep up now. Imho

Wasnt rushing anything, just asked if one already exists, since I couldnt find a standalone kernel. Would seem logical for CM10 AOKP kernel to be out, given that both AT&T SGS2, SGS3 already have it and it least 2 other CM10 based roms have either h0tkernel or flapjaxx kernel integrated and both support overclocking. Imho, DAGr8 did a great job and this rom is stable plenty enough and stability should have nothing to do with custom kernel availability
are there any linaro optimized cm9 roms for s3?
Linaro is for kernels... Its a tool chain used to compile kernels. Nothing to do with a ROM. Why are you still on CM9? Developments done...

i need ics, and i heard that linaro output perfomance is greater..
i just dont know much about these toolchains..
Omg... You have the chance of SDS on CM9. linaro hardly made any difference performance wise. So just update to CM10.1 There isn't much of a noticeable difference if any at all.
dont freak out, ALRIGHT
he's trying to help you
You're on ICS, SDS very likely to happen.
What do you need ICS for?

It says AOSP, and I dont think we have any 4.1 AOSP ROMs, just 4.2.2 CM based ROMs.

Any idea, on what ROM will it work?
I'm going to add a few things like voltage control and two govs and then work on performance and speed like I said based on what your CPU is binned is how your device will clock

I am probably getting excited for nothing but if I do use this kernel with CM10.1 will it take care of all the bugs like audio, BT, and camera
no all of those things are still a work in progress and i cant work bt anyways i dont have a headset but i am going to try i fix audio not sure how fast i can work as im still learning the ins and outs of coding
I haven't had a chance to search or ask Crpalmer about this...but could you add in the 192mhz clock speed? Since one of his updates to the CM kernel, its only ever had 384mhz as the lowest select-able. As far as I know his sense kernel still has 192mhz in it. Just a thought!
I clocks added all the way down to 100 MHz but for some reason I can only get it to show 384 _ 1512 mhz

the reason crpalmer/chad removed it was because now at 384mhz it uses the same amount of power as the 192mhz clock did, so now it does more for less power basically
Is this gonna be dependent on cm builds? If so, you might wanna designate dates like in Palmers thread

Odd..I flashed this and it made illusion laggy. The settings say 3.4.10 and the clocks low and high are 384/1512. Maybe this is just alpha and you're working on something, but I still thought I'd report.
