Release Of Kernel Sources & Custom Rom Development ?

Will Xiaomi release kernel sources fully for this smartphone & therefore able to have active rom development (including Android M 6.0 roms) in the near future ?
(Kernel sources for the Xiaomi Mi3 & Mi4 were released very late and not in full and are the reason I believe that many Lollipop roms for these devices are not stable).

I think it depends on whether the device goes international. They were quick to release the sources for the Mi4i, and that is the only phone they officially sell internationally. That said, at least it uses the most common SOC of 2015.

Does it help that it has the same soc as the nexus 5x?

It helps a little bit maybe, but the problem is all the other stuff inside the phone is different. You still need proper sources from Xiaomi.

Do Xiaomi devices have root "built-in" ?
I'm interested in ROM development, too, but for the first months having root would be enough.

Having access to kernel will also mean ir blaster will work on custom roms?

Don't count on that. Many device that have kernel source and ir blasters still don't work on aosp based roms. Due to all the drivers for the hardware being closed sourced.

When we say kernel source, is that pertaining to the soc?

The kernel covers all aspects of the device in one form or another.

Let's say xiaomi is taking long to release their kernel source but the source for nexus 5x soc is out, would that be enough for aosp rom?

No it won't. You will also need the device tree for this device. It's not how long it takes for them to release it that I would be worried about. It's if the source is complete and not broken like they are known to release. They have a habit of release broken source to force users to use miui. If you look at other devices from this OEM it takes months some times a year before they release it and when they do it is broken and devs have to take weeks to get it even remotely working. Then there are still bugs that are never fixed.

Q : Pure AOSP + Caf rom is possible?

Hello Everyone. I'm just N5 nomal user during 2years and I had question so write this text.
I googled about AOSP / Caf and understood like this.
AOSP was handling by google, have some feature.
Caf was handling by qualcomm, more performand and seek stabilization.
Question is, Pure AOSP+Caf rom is possible?
Developers offfer to us CM-Based Caf (hammerhead-caf) but I didn't heard about AOSP + Caf.
Did I have wrong thinking?
As I told, I'm just commly n5 user Please expain easily.
Have a nice day.

I think we cannot. CAF and AOSP are in two different line. If they can be combined, there must be a version of android like that now

Moto g 2014 has an aosp caf http://forum.xda-developers.com/moto-g-2014/development/aosp-caf-6-0-t3284309

But we already use CAF lines rom, like CM-Caf.
Dev. said, Basement is AOSP-CM and put in CAF source to it.
I had more curious why Dev. are don't use AOSP, just connect with cm

Kernel source availability for The Nokia 3 and other models ?

When is Nokia going to release the kernel source for the Nokia 3 ?
It would be of much help if Nokia will give out the sources for aftermarket development.
If u by any means get hands on it, please kindly share.

Yeah I know but it would be good enough to ask them.
I was previously on a Motorola device(Moto E4-woods) the mtk variant, which we had to ask for kernel source before the released it.
Am currently trying to work on custom Roms for Nokia 3, but going with stock kernel isn't enough.

we can still port roms without kernel source, but we need to find rom with same cpu, gpu and same kernel version.

[KERNEL] Major Linux Updates

Hello, I decided to come up with a project that aims to port higher Linux versions. When I say higher Linux versions, I mean those that are Linux 3.5 and up. The goal is to port Linux major updates as high as I can, but the main priorities are one that are LTS like Linux 3.10, 3.14 or even 3.18.
Only Android 7 will work on non-LTS versions. Oreo/pie and Android 10 support will be added only on LTS versions to lessen the conflicts when merging non-LTS versions.
What works:
Boots
Battery
Charger
Touchscreen
Display
USB
Sound
Buttons
Deep sleep
Camera
Video playback
Fingerprint
The rest of the sensors
WiFi
Bluetooth (works on Linux 3.7 and up)
Internet connection
Anything else I can't mention
What doesn't work:
You tell me
Drivers that can't be updated (yet) due to them being heavily modified by CAF and Samsung:
USB
Sound
MMC
Newer versions are more stable than the other due to the fact that I fix more bugs with every update.
The highest version as of now is Linux 3.8. I can only merge major updates during weekends due to my work.
Sources:
Linux 3.5
Linux 3.6
Linux 3.7
Linux 3.8
Linux 3.9
Feel free to open up issues and submit pull requests
It is highly recommended to delete mpdecision from /system/bin/ before flashing

These are kernel updates. Our device comes with Linux 3.4, but I've managed to update that up to 3.8

What a Huge Task! As Well as a Pain on the Ares!
Now, I do Have a few Q's for you.
1 IS this "Kernel Patch" Just for your beloved Galaxy S5's ?
2 Will this be for the "Basic" Kernel in an OS (e.g. LineageOS) ?
3 Wouldn't this hurt some of the "Custom Kernels" that we currently have and use?
And of course I must ask, how far do you intend to take this (e.g up and coming 5.7 ) ?
That Said, I am in! I have downloaded all the Kernels . Mostly to compare your changes. Have also saved your GitHub page.
Am wondering though, With some of these "Custom" Kernels..... Wouldn't we see much faster , smoother , and hopefully more Darn Battery with some of the Tweaks that we have with them? Or at least with some kernel manager?
Or, would these break those Kernels (now thinking about it)?
Certainly will be watching this!
Again , this is a huge task to undertake! Sure would love to see 4.1 and above for our phones. Maybe with Your updated Kernel, we could really see some major changes with our phones.... Plus, hopefully easier to Port into the likes of Android 10! ... or Of course jumping a bit here, and a bit positive, but Android 11 !
Good luck sir

1. This is a full Linux upgrade. Nobody has ever done that to our beloved S5 cause it's a truckload of work
2. Uhm, I don't know. LineageOS is very strict on what kernel base to use, but I may propose to use this as a base when I reach 3.10
3. This project might be a good base for custom kernels since it is more updated and I will use this base too for my future custom kernels
4. As far as I can and as long as it works. Of course, I don't wanna die yet by not going too far.
Certainly, it won't break any kernel managers. You can even clone the latest source and add some custom features. It's up to you, but right now, in the process of upgrading, I won't be adding any custom features

YES your project is a HUGE amount of work. Good guess, IS , you seem to want to take on this challenge! Good for you...
Yes, I do intend to really follow your project. Really looking forward to the great results that I hope we (you) can achieve !
Awesome...

Hi guys! Linux 3.9 is up!

this is amazing work!
thank you very much for it.. I bet it's ugly as hell, but you learn a lot..
I'm patiently waiting for 3.10.0 since that's required by docker (running debian using Linux Deploy)

Nope, S5 only. And at this point klte only until @pascua28 is finished bringing the kernel up to 3.10

Only working properly is klte, for now. Other variants might work but with bugs. Will fix for other variants when we get to 3.10

3.5 to 3.9 didn't work for me,I have klte

Question Anyone want to collaborate to port LineageOS to Tab P11 Plus?

It's a mediatek processor and supports SPFlash byapss in case we screw up we can still recover...
Lenovo posted the 4.14 kernel, I tried building it and it seems to compile without any errors. Just need help getting the proprietary blobs and to build a device tree.

What's the model number of this?
I have a P11 TB-J606F
I am a developer, but I have no knowledge of how to extra the blobs ?
Can you post a link to the kernel sources ?

That is the snapdragon variant, likely much easier to develop a custom rom for...
I am talking about the mediatek one which is the cheaper model (although they call it "plus")

You can get the source from lenevo's open source website and search for your model...
There are scripts floating around that can help you extract the blobs from your running device or a system image.
You'll have to make a device tree though

You might have a lot of work to do then. You can compare with other tablets with the same SOC. Snapdragon is very common and they release their own source as well and can rebuild the kenrnel.
You can use that guys kernel and see what the panic is to figure out what he is missing. It's def possible!

Yep. Probably a year old kernel should be fine, and the other guy's kernel probably has a miss configuration

anyone out there to test custom rom for P11 plus? I have compiled it but I haven't received the bootloader unlock email reply so cant test myself

Is LineageOS working on this tablet? I recently bought the tablet for my son (on a whim, without doing much research) obviously a fault on my part but i was hoping someone smarter than me got it working. I don't mean to come off rude demanding anything, just hoping someone has it working.
