I'm aware that the kernel source for the Vega is being released at the end of the month, but was just wondering what advantages a custom kernel will bring? Will it allow both cores of the Tegra 2 to be used? How about overclocking and fixing the WiFi sleep issue? Will it be able to fix ClockworkMod instability?
Does anybody more knowledgeable than me know what benefits could come from a custom kernel? A lot of questions, I know, but would help me see where development with the Vega is going.

Overclocking and wifi mods certainly possible once we have kernel sources, as are other little tweaks that can make the rom work that bit better.

Good to know, the WiFi sleep thing has been doing my nut in! Really want to see how well a overclocked Tegra runs as well. 40nm, wonder how far it'll go

Hey devs,
I wondered.. Why aren't there any overclocked kernels out there yet? Surely we want this baby to run as it should with a nice overclock. I mean, after seeing the news of the Xoom beeing overclocked to 1.7Ghz I kind of got disapointed with there not beeing any progress here yet.
Why is that? Isn't it possible to make custom kernels yet? Is it hard to do something like that? Or is the device just not populair enough so noone is buying this thing.
I quite like the device but I feel it is a bit quiet in here, also find that the software on the device could use loads of improvement (already made some speed improvements myself)
I would gladly be donating to anyone who comes up with some good software or kernels
I didn't read your entire post but..
we don't have the kernel source yet. samsung should be releasing it soon.. probably when the tab is released in the US.

How stupid of me. I thought it would just be as easy as making a backup of your files and then using these files and edit them. I haven't said anything then, can't wait for this thing to bbe overclocked.
I love the stock ROM so far. Coming from a rooted Sammy 10.1 that had the full tablet UI, but I think with the 7" for factor the stock feels rgt for a change. I still would like to root and get whatever helpful mods on here that I can. An OC kernel with better battery life is always great too. What choices do you guys recommend for what I'm after?
Rooted with stock is working fine for me at the moment. I wanted root just to get otg thumb drive support for more space for my 8 Gig rig. I could not pass up that $200 price tag and still get some 64 gig loving Lol.

Can I use a custom kernel with rooted stock? Will it work as well? Maybe a bad question.
Most ROMs and kernels are so early along that you better be prepared for stability issues.
My recommendation is that you go look around the Android Development forums and the Original Development forums. Everyone has their different preferences and styles in their choices, so nobody here will be able to tell you exactly what to use.

Yeah. I read around and it does seem early bit the kernels look good so far. 1.5 with some undervolting seems stable. But the hybrid Roms aren't what I'm looking for. Maybe a cm10 when its ready.

That statement is very misleading, as there are several ROMS with zero known issues whatsoever, and kernels too. Sure, most of them are unstable, but you only really need one of each to be stable. For example Trinity is totally stable, never an issue with that Kernel. CM10 is stable as far as I have heard, I have not tried it. But I have used AOKP and encountered not the first issue since installing that wasn't cause by apps not liking JellyBean(which would have happened on stock). My advice is, root then backup stock. Then toss on a few ROMS and see how you feel about it. Can always go back. It's the rooting itself that voids your warranty. Once done there is really no reason not to try on a few ROMS. If it's stability you need stick to CM10 and AOKP in my opinion. Most other ROMS are simply based on these with more things added, and that is where your stability problems usually lie anyway.
Paranoid Android. It has everything I wanted that wasn't included in the stock image.

I loved PA but i had major problems with it, sadly, that required me to move on to another ROM.

I've used Trinity Kernel a few times now and have had stability issues, even without overclocking. I think it has something to do with deep sleep, but whatever it is, it's frustrating. I'm gonna wait a few weeks to let the problems get ironed out before using it again. I'm on CM10 at the moment, and for the most part it seems rather stable, but I do have random issues here and there, and I don't know if they're related to the ROM or not. The only reason I'm on it is because I'm a bit flash happy, and just find the nightly updates exciting.
For most users, my recommendation persists, stick with stock and give the development a bit more time. If a user is feeling adventurous, then your advice definitely applies: Get a good backup, and explore with a multitude of ROMs, for everyone has different tastes and preferences.
Well dear all the people talking about stability issues:
Not flaming, just expressing my opinion:
Morfic's trinity kernels are still experimental releases, I wouldn't be expecting stability because they are not classed as 'stable'
I used earlier versions of his kernels and faced no problems at all
So it depends on which kernel/kernel version as to whether or not its stable
I am on AOKP build 1 and using Faux's 008 mainline kernel, it works very well, super stable and super quick
No issues at all here, I guess because I am on two stable and tested releases
Will this help development of ICS and JB ROMS? http://www.engadget.com/2012/09/23/nvidia-to-offer-up-documentation-for-tegra-graphics-core/
This should solve the video camera issues and other issues I think.
It's the documentation for the Tegra chips.
Looks like a good news and a bit of light for ICS+JB for our Atrix. Lets keep waiting...
No idea, but good find nevertheless.
Assuming this is released, what else will be needed to release a stable CM9?
It really depends on whats is going to be released. We don't know if its going to be useful yet.

Yeah it will help even to make better kernels, is a shame that my Atrix touchscreen died totally two days ago (thread reported will move soon, does not belong here).

Once Tegra2 graphic driver source is released, Atrix devs then just simply update and compile the expecting module (.ko file) to put into the kernel of their roms

Thank you for your replies, guys!
So, with the graphics drivers into the kernel we would get 100% working roms?

I'm not particularly knowledgable about the ins and outs of Nvidia's modules so I might be wrong here, but I seem to recall a dev on this forum saying that is wasn't just a matter of the binaries being compiled against a different kernel (which could be worked around if it was just version checking), but that it depends upon functionality that only exists in newer kernel versions.
If somebody on this forum were skilled enough/had the time to donate to port the Nvidia 3.1.10 sources to the Atrix, we could have fully functional ICS/JB today. But it's not reasonable to expect the few skilled kernel devs here to make up for Motorola's slack.
Over in the One X forum, richardtrip has ported the reference 3.1.10 kernel using only a few bits of hTC code for the camera, so it is certainly possible for somebody without 'inside knowledge' to do, but it has taken him months of hard work. (we're on 2.6.39 'till hTC's official jellybean drops, which uses a 3.1.10 kernel anyway)
Well.. there is still the matter of the fingerprint scanner beyond the kernel. But we can't get too greedy now can we?

The phone would probably be functional without a fingerprint driver, though.
This is not kernel module source they are releasing; they are just saying they are willing to provide more information to the opensource community. NVIDIA has recently indicated they may provide documentation to those working on the nouveau drivers (opensource NVIDIA PC drivers); under an NDA. Meaning that they will provide the documentation to those that work on the opensource driver but not allow the information to be shared. For this to be helpful we would need the documentation provided to someone who is working on opensource Tegra drivers; which I do not believe there is anyone. So this would probably be picked up by those working on the nouveau drivers. Best case if all the information is provided and they decide to work on it it would probably be at least a year before we would have anything stable for use.

Just wondering if anyone knows why we haven't seen a linaro Rom yet?
Is there a special problem that 4.3 presents?
(And for those of you wonderful souls about to write "give them time! Don't you know development takes time! Be more grateful! Etc...", in asking out of curiosity, not out of complaint )
Just interested if there is any special challenge that 4.3 presents!

linaro..
first of all, when you say linaro, are you asking about the linaro toolchain or the linaro patches? they are 2 different things. what are you asking about?

I tried but didn't see significant performance improvement of Linaro. Also 4.3 custom ROM's are still not stable (for me).
Anyway, wait a little bit, you will see linaro builds of nearly all ROM's on the forum.

Minimus ROM is a perfect stable way to go. PA 3.94 is also stable, although some features are not fully working.
With stable I mean not reboots nor force closes at all, or any other weird behavior.
Most of the AOSP build out there are pretty good and stables.
Hey folks, I have a question... Is it hard to port MIUI to Marshmallow for our phone? I love the MIUI Interface, but I wanna move on from Kitkat, and on Lollipop the phone overheats. Besides, all the 4 core are always on and I haven't found any solution for that yet. I'm not a developper but I'm willing to learn if there's a way, which doesn't require much knowledge in development. I appreciate any help. If it's not possible, I'd appreciate if at least someone could help me with making a kernel that boots on MIUI based on Lollipop, which can turn off the cores that are not being used, automatically...
As MiUI is closed source there is NO chance you can contribute directly to source.
You can lend a hand by joining the beta team and giving feedback on what progress they are making towards update.
BTW,kernel governors are used to control the behavior of processors.

Stay aosp anyway if you have 1gb ram, MIUI is too heavy.

I have 2gb. I dont think MIUI is too heavy. The issue for me is only battery. Im happy with the performance this phone gets on any ROM in terms of speed. But battery... thats another story
