Android OS & multiple core utilization - Android Software/Hacking General [Developers Only]

So now that dual core cellular devices are not fairy tales, and about to be in the hands of consumers, I was wondering if people can chime in with knowledge on Android OS and how it will utilize dual cores. From my understanding I believe Honeycomb+ will support dual cores. Specifically how will the OS manage the cores etc.
Just trying to gain some knowledge and insight.
Apologies if this has been asked or if we need to move this into a thread.

Found the answer I was looking for. Just in case others wanna read up on it.

android subfora

Running a title-only search for 'android forum' yields quite some many results.
it seems like many on xda want their own android subforum. polls show that most think it makes sense. I agree with that because for people not interested in anything linux based it's totally annoying to have android threads everywhere. on the other hand if you're looking for some linux based / android image it's easier to have a special place for that.
So it's overall a good step imho.
The reason for posting this thread is that I have some thought on that:
It might be better to put one main forum instead of many subfora for linux/android:
Many htcs with the same chip share the same linux codebase and can run the same android/ubuntu/whatever roms. Also most of the msm7*/qsd8* device forums have at least one linux/android topic thread. You will end up with one linux/android subforum for each device.
=> development processes and rom distribution are eased when focused in one place.
It's not ideal to create *android*-only subfora.
Since there are many linux distributions you have quite some stuff that won't fit an android subforum.
Let's say you made some ubuntu image for the blackstone you want to share. Blackstone android rom development is the wrong place then because ubuntu is, just like android, linux based. And not vice versa.
Same if you have a question about a linux driver on your blackstone. Same problem. That'd be linux kernel related and has nothing to do with android.
=> It is better to use different naming. e.g. linux & android rom development. This will reduce confusion and make the splitting into wince / linux based topics more efficient.
My 2 cents

Doesn't this do the trick?

I forgot to mention that I'm talking about the devices that support linux non officially!
I'm sorry for causing confusion.
Well still your answer would make sense to my first point.
Forget about that. I guess it is better to have those device specific linux/android subforums in the device main forums! Cause that's where people are looking for them.
Still concerned about the second thing about the subforum names though. Could you give me a thought on that (now that you know I'm referring to the non-official linux/android devices)
I think they should really be Linux (and android) subforums, and not android only.
Ok, so just to be clear, you think that we ought to rename the device-specific Android forums for WinMo device (like Blackstone, Rhodium, etc) to include Linux? So instead of:
Touch HD Android Development
it would be:
Touch HD Linux (Android, etc) Development?
Like that? I know that some other operating systems that run from Linux have been shown running on some of these Windows Mobile devices, but 90% of the Linux dev work is being done on Android. Perhaps this may be a good idea in the future if we see Ubuntu/etc development pick up, or do you think we need the change today?

Yes I would suggest to change the current subforum names to something like that. So that people know everything <device>-linux related can be posted there with any userspace they like. Still it is important to put android in the name because many people just look for android and don't know that it's based on linux. So the pattern you propose seems perfect.
I agree. Obviously most of the users want to run android userspace on their HTCs now and that's what the biggest part of the discussions seems to be about. Still I would change it in the proposed way already for two reasons.
With the current titles not only discussion about non-android userspace is excluded but also everything kernel related. And the kernel is very important. Of course also for android.
Also, people who want to develop non-android linux based stuff like ubuntu for HTCs might not be much attracted seeing a (seemingly) android-only forum. They will rather publish/discuss their stuff elsewhere because it might appear to them that only android related things can be released in the xda forums.
Thanks a lot for the attention payed to this!
Plz rename Android section to Linux?
Or give us a Ubuntu section like Andriod got its own (Still both Linux thou)
Im happy for all who want Android on there WM, BUT for me i have second to non intrest on getting it on my HD2, like WM 6.5.3 and NRG keeps making WM more and more perfect everyday (Love to NRG and...HOW The hell do you do it!=)
My intressts are fully on Ubuntu news and just plainly, talk about buggs and leave feedback and we are drowning in Andriod threads. And atm i feel there is no way to find peace and calm to engage people to this. Ubuntu or other Linux work could grow, given only a chance.
Anyway i hope this getts a solution since its trying my patience. So i agree totally with Dcordes, we need a change
I know this thread is a little old, but I think that changing the forum names to include linux in the title should be looked at again. In the HD2 Android Dev Forum there was a thread asking about porting meego to the HD2, and it got a quick response from a member saying "maybe when we have a meego dev forum" and continued to post responses against it, when there are several people interested in meego or maemo. Its all linux and the forum should be called HD2 Linux/Android Dev or something similar to avoid confusion.
I feel some of the users won't get it that *Device* Linux Section is the one which contains Anroid ! They might start asking for a seperate Android section again.
IMHO.

[COMPREHENSIVE DETAILS] nVidia Tegra, Qualcomm Snapdragon Development Roadmap

Hey guys, I have written and compiled information of the entire Tegra and Snapdragon roadmap and added some information to it.
http://www.seednonym.com/2011/09/nvidia-tegra-nd-qualcomm-snapdragon.html
Please have a read share your thoughts and views regarding this on-going major development and point out any mistakes you came across.
Thank you.
There is also SoC from TI OMAP but their roadmaps are still limited and development status is currently quite static.

[Q] Not Sure Where to Post New Project

Hello,
I designed and built a coffee table with an integrated screen running KitKat 4.4.2. It has 4Gig of RAM and the CPU is a dual core Intel celeron clocked at 1.8 ghz. I want to post pictures and in depth descriptions of everything. I would Also like to receive feedback and constructive criticism, but I have no idea what section to post in. Any help is appreciated.
P.S.It has an AnTuTu benchmark of 3658.

I am not an expert or moderator or something, but since you bumped this and seem impatient I know that there is a subforum where developers post their Apps and Games which is probably not what you want. However, I see that that subforum is under this forum http://forum.xda-developers.com/android ("Android Development and Hacking") which includes another subforum titled "Miscellaneous Android Development". Have a look into this and see if it includes what you want to post about.
Coffee table with an integrated computer sounds like an interesting thing :laugh: I will keep an eye to find your thread when you post about it!
Cheers
OK thanks. I will try there tonight after work. Appreciate the help.
Yeah, My little 2 year old brother has been playing non-stop on there for the last two days. That's the first thing he wants when he wakes up...lol

OnePlus X - will I be satisfied?

So few days ago I ordered OnePlus X and can`t wait for it, but as far as I go I`m getting worried that the specs is too low for 2016 smart phone. I`m planing to use it at least 1.5 year and I want it to work as fast as any high-end smartphone. So I`m asking you guys if that Qualcomm® SnapdragonTM 801 processor with 2.3 GHz Quad-core CPUs; Qualcomm® AdrenoTM 330 will satisfy me after a year or so? I`m planning to use a stock android rom with a custom optimization, for the most time I will be using this device for web browsing, messaging and few basic games/apps (For example: Crossy road, Youtube, Spotify) the most important thing for me that everything would be working as fast as possible. What do you think? Is this device is the right choice for me?
You could read some review threads in the device sections general area here,
http://forum.xda-developers.com/oneplus-x
And decide for yourself. But if you must ask others , then here's a dedicated thread for such questions,

Does Mediatek SOC´s also have EFuses like the Qualcomm Snapdragon has?

Hello.
I am new in the Smartphone modding topic, and I also dont know if this belongs into this subforum, if not, sorry mny times, please move where it belongs.
I want to know, if Mediatek SOC´s have also irreversible EFuses embedded like the Qualcomm Snapdragon has?
How do they handle their chain of trust, Snapdragons do it by signatures that are "etched" in the SOC by blowing EFuses, that cannot
be resetted anymore, but I never heared, that Mediatek uses EFuses?
Regards.
It's amusing that no one would answer this post. Lots of people know the answer to the first question, and couldn't be bothered to answer? What a forum XDA is.
Yes, MediaTek processors have e-fuses and, yes, one of the purposes is for configuring verification of the first writable software stage to run on the device by the boot ROM. All of this configuration is irreversible.
Unlike virtually all devices that use Qualcomm chips, there are many MediaTek-based devices that aren't made by either Lenovo or one of the big non-PRC brands do not have restricted boot enabled. The high-end devices like Xiaomi and Oppo are now starting to use it though.
Details on the exact e-fuses are very scarce. There is a security configuration document that I've seen referenced by leaked MediaTek SoC technical reference manuals, but I have not found it myself.
