So what is involved in porting aosp to a device?

I'm just curious what's usually involved. I know cyanogen mod does some custom things but ignoring those customizations, what is involved exactly in porting it to a device?
I would assume the major hurdle is driver support. As in the linux kernel compiled/used has hardware support for device x. But other than that, what else?
For ex, with the nook color, what is needed to port it? We can't expect a recent kernel for the nook color from barnes and nobles, but what about the existing kernel used in cm7?
Or if it's not just a kernel issue what are the issues/hurdles. I'm not a developer but just curious from a layman's point of view.
I would think if a working kernel is ready, wouldn't it be just a matter of compiling? I guess I'm curious as to why some say it takes a month or so.

First we need an upgraded kernel to even think about ICS. Then there will also need to be drivers written/rewritten for hardware acceleration and such. Also many other things that will need to be put together to compile even a semi-working rom.

I hope by Xmas, CM team will prevail new ROM running ICS.
I don't care it called CM8 or CM9, as long as it's ICS supporting NC, I'm happy

Slight thread-jacking here, but somewhat related:
Kernel wise, what's the difference between an SDK port vs an AOSP port?

The SDK is used by devs to create apps so only code relevant to having a semi- working simulator is present. AOSP is the full source code, witch includes everything but it is only built for one device, the galaxy nexus, so there is still much work involved in porting.

Android 6.0 is being uploaded to AOSP

Android 6.0 is being uploaded to AOSP:

@Alberto97
 @Flashhhh
What do you think ? it will be difficult to port it over ?

Too early to say.

I hope I can find some custom rom after Android 6.0 release.....

The 2nd gen moto g is being updated via motorola to 6.0, the first and second gen motos are pretty much similar in every aspect part screen size and camera. Roms have been ported over from the 2nd gen to the 1st gen before so it maybe done again for 6.0.

Lets hope for the best...

CM13 branch is created, also with falcon device tree repo (https://github.com/CyanogenMod/android_device_motorola_falcon/tree/cm-13.0)

I don't have any knowledge about building Android. But I have 2 questions:
Why the compile can fail ? There are no drivers ?
If compiles then we need to see if it's boots and if at least 2-3 things are working. like wifi, or something like that. I am just interested.

Millions of lines of code -> millions of possible reasons for failure.
Also, the closed source libraries (lib/hw/* and vendor/lib/*) could be incompatible and workarounds may need to be found and implemented.

If you compile it and it works then post it

This could take weeks or even months, not a few hours.

If anyone needs beta test I am available and only send a private message

first, the downloaded sourcecode was only about 2gb (normal AOSP sourcecode is more than 20gb)
then, they are still updating many repos, you can watch them update https://github.com/CyanogenMod

ok so then we have to wait at least 1-2 weeks to get Android 6.0 on our device...

Avoid the impatients
Lets avoid asking for builds and ETAs please, remember that devs have jobs or study to do, and sometimes being bothered about when they will release something could annoy them.
Rule 4

I'd be open for testing any kind of builds in the future, although I have the xt1031 boost variant but that might help out too for certain things

So our Moto G 2013 will receive the Android 6.0 with CyanogenMod 13 ?

[WIP] Sailfish OS for OPX

Hello OPX community,
I started to work on the port and its progressing nicely, UI is up also Wifi works now, but many things still don't work, so help is defintly appreciated.
Current status: wiki.merproject.org/wiki/Adaptations/libhybris
OLD:
I don't know if some of you know Sailfish OS, but its an OS that is not based on Android with an outstanding UI and UX.
And developers can port it to Android based devices like ours \o/
So I took the hand and compiled Sailfish OS and Android, but unfortunaly I don't really have the time to test since this is my only phone.
So I need someone to either test and report to me or what would be better someone that can develope further on its own after I shared my knowledge with him.
This thread is for talking about everything related to Sailfish OS.
Here are some useful links:
Jolla.com
Sailfish Porting
HADK

+1
This would be my dream coming true...
I might be able to test it, if You can make a flashable zip. Is this build supposed to support android runtime? If I flash it, my recovery and internal SD remains untouched?

Android Support is currently not available for ported devices but there are some devs working on an open source solution.
Your recovery will stay the same.
Internal SD should stay untouched of you don't wipe it but it will probably not visible from sailfish but there was a fix for that, dunno if that is already upstream.

Still having Jolla with me and running Sailfish OS on OpX hw would make it sweet.

I haven't heard about this OS, is this some custom ROM, CM based? or what? :silly:

It's a completely different OS, it's based off Mer which is kind of a Linux distribution and on top of that sits sailfish OS. CM is only used on Android via libhybris to get the hardware working. In fact it's completely different from Android and NOT based on it like CM. It's real Linux as a mobile OS.

Wifi up
Bluetooth up
All sensors up
Audio up
\o/

Nice progression, thanks for effort. Had a Jolla-device before and loved it. The HW build quality just wasnt there. Altough, I'd love to get the opensource dalvik-emu to work some day, since I have a bad feeling about future sw development on SailfishOS.

Awesome. Sorry I haven't been able to get back to you on the latest build. I haven't had time lately. Life kinda showed up abf took my time with it. I'll try to observe it later.

Sim is now detected and mobile data is working after adding your apn to settings \o/ video and music playback should also work now and RTC alarms are working so you never need to worry if your phone is off you won't miss that alarm

I could post it in a few hours, but than you don't have a camera, no LED and probably no calls (needs to be confirmed)
It would really be only a test build.
If I should do it, write it now
EDIT: Ah also Jolla Store is not working atm needs to be resolved server side. But there is still openrepos.

Why don't the devs work on lineage Os together?

Just curious.. why is it that we're seeing rom after rom drop.. all based on lineage.. but lineage isn't official yet.
I understand all the hardware needs to work before it's official. So why not fix the base rom instead of just building everything we see?
Again.. I'm just curious. I used to build ROMs too and always liked to base stuff on fully functional code.

I have. I've also 'listened' in on the conversations in the chat rooms.
Most just want recognition for building their roms. Some will help occasionally but the primary focus is "thanks" and xda recognition NOT completing the base rom or getting things official. I completely understand why vache won't work on official since he doesn't have the device.. but there are many others that are more concerned about the things stated above.
I tried to word my initial question do I wasn't insulting the devs.. but.. after your statement I felt the need to clarify.

Well to be honest you have a point there

Yes. Instead of so many ROMs, we need stable ROM. Even one LOS should be good enough

Future of OP3T

What is the future of OP3T concerning roms? I know One Plus will not provide support after the O update, so well have to get our taste from custom roms. Why are there so many resurrection ROMs? Does anyone still use all those features anyhow? I can't tell you the last time i heavily modified my rom. I typically stay on PA, FreedomOS, or stock rooted.
Does anyone know where I can find some AOSP kernels?

no one said O is end of the line for 3/3T, it's the end of beta, they cant keep 2 beta's
that's said, even if that's true, there will be plenty of O custom roms, and probably P when it's released...
AOSP kernel, hmm, ther was one i don't remember it's name i'm not sure if it's still maintained, look for it on the cross devices section, it was the kernel for the OSIP rom.

Personally I think it's crap that this phone won't get any software updates after Oreo. Phone should have shipped with 7.0 out the box. This will definitely be my last OnePlus

There will be no Android P without the source code which One Plus won't release because theyre stopping after Oreo. Oreo based Roms will be the final Android version.

I'm sure there will be custom roms after Oreo (not OOS based tho ofc), same as Oneplus 2 have nougat as custom roms.

Actually I don't know how that goes, since I know nothing about developing ROMs, but since there is new OS versions for devices which didn't get them officially, there must be some way. Some functions propably not gonna work similarly, depends on device tho (Samsung Note 4 example.. custom ROMs were missing all "S pen" -stuff and camera quality was horrible. All camera framework stuff were binded to Touchwiz itself), but atleast our Oneplus 3T is quite simple device and camera is so far working "good enough" even on custom ROMs.

The source code used for custom roms is based on aosp(google)not on the one released by oneplus. Basically the one on pixel and nexus devices and mixed up with oneplus drivers( blobs actually)..
So no. Custom roms will continue till developers stop making builds.years after oneplus droping support

This phone is good for the next year at least. People will still have it since it's like the budget pixel

even OPO has 7.1.2 custom roms, why you need to worry ?

Not really. The code oneplus release, the blobs and the devices trees can help to improve custom ROMs, but custom ROMs won't disapear if we doesn't have the source.
Just look at the Xperia SP for example. Official android version, 4.3. Android version thanks to custom ROMs, Oreo.
The code the manufacturer release is highly important at launch, to have a base to work on to port a custom ROM. On android P developers will take the android O tree and start to update it to support the code changes of P, without the need of OP.
