Kernel 64bit? - Xiaomi Redmi 6 Questions & Answers

Hi there
I saw a good thread there https://forum.xda-developers.com/t/...ource-for-cereus-probably-cactus-too.3892789/ which tell me the is little chance to get a stable / full fledge 64bit kernel for Redmi 6. Even after Xiaoling released source code. Which imply that guys like me who want to run 64bit ask need another and newer device. Do you confirm? Thanks for any reaction, expertise, encouraging

ELI5 Kenel Source Code

hello, so i have been in communication with huawei regrading the kernel source. i mentioned the lack of source files for the mate 7 and how its part of the google/android agreement that oems must share all relevant sources for devices that use any part of android. they replied with the usual reply about how they will work hard to resolve this issue and whatnot. the rep did give me a link to the kernel source which i believe is for kitkat but i cant be sure so i hope that someone can verify.
having said that, why cant the kitkat source be used to build for lollipop and marshmallow? im still using a nook hd+ that is running MM......... WHAT??? how is this possible if the only kernel provided was for ICS? anyway, im going to keep poking at them until they either give up the LP/MM sources of they tell me to ****off. so, if anyone can please check out the link i would really appreciate it.
Lollipop Kernel?

What is necessary if I want to compile a ROM?

Hi guys. 2 months ago I've came into Android World deeper than before and now I'm very fascinated. I downloaded linux, all the necessary files to compile a rom but I still don't understand some things.
My device is Redmi Note 2 and I use stock MIUI 7. As we all know mtk and/or xiaomi haven't released kernel sources (6795) so developers have to think hard how to make a rom. And there are my questions. Does kernel source is really necessary? What if I compile rom successfully and then port boot.img from stock? Will it work? However developers made some roms based on LP for this device. And I read that I need device tree and vendor, which doesnt exist for redmi note 2 or I still can't use github.
Second question which I have is: does compiling for 64 bit CPU differ from compiling for 32 bit CPU (like 6592)? If yes, could you give me some tips?
Ohh I think you can understand what I wrote
Thanks in advance and please dont blame me for silly questions
If you are looking to compile roms then you picked the wrong device to do it. They are the worst with kernel source. You can't completely compile a rom but use a patch system that does most of the work.
Yes it is different. There are some Tuts around but they are few as most don't use that type of chip.
If you really want to learn to develop then I would suggest getting a different device. One that respects the copyright and gpl laws.

To compile a rom u need kernel source, device tree and proprietary, bye

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.

Nokia mostly don't give a **** about customers, so no kernel source

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.

[HELP] Need help upgrading to 64bit

Hi Mates! I am kinda late in 64bit rom party. I am trying to read as many as possible post just to understand it. First, if i upgrade to 64bit rom, can i play some of the 64bit games that is not compatible with our device. Second, can you explain the process. No need in pointing the link just the files that i need to download and flash. Thank you so much.

Have a look here about the meaning of 32 and 64 bit hardware and software:
What is the difference between a 32-bit and 64-bit system?
An explanation of the difference between 32-bit and 64-bit, and what the terms mean in reference to hardware and software.

Hope that helps to understand the difference and how it works together.

Afaik if you have a G610X device then natively the phone supports A64 which means Arm (32-bit) with 64-bit binder. This means that the OS is 32-bit while the hardware is 64-bit capable. There now exists vendors that cater to both Arm64 and A64, Treblue and TheRealVendor respectively. If you like to go Arm64 (A-only), try Treblue vendor and flash some GSI's like Crdroid, LineageOS, or Havoc, among many others. If successful, then yes you can start up 64-bit (Arm64) apps and games, albeit it may be really laggy as the phone, while 64-bit capable hardware-wise, meets the bare minimum to even run these newer games and apps. But at least you can use them to some extent rather than not on Arm and A64...

Thanks for the answer bro. I already flashed HROM by Astrako. Last thing though, can you recommend any GSI/Pixel like rom? I was wondering if there is any semi stable gsi rom. I'm kinda craving for new ui.

Lots of GSI's to choose from like LineageOS, HavocOS, CrDroid, Corvus, Pixel Experience, FluidOS, AOSP, etc.... Just check out each to see which fits your needs. Just make sure that the version you are getting is compatible with your vendor.

Samsung A13 (sm-a135m) 64bit kernel building

Hi Everyone!
I'm very new to this topic, this is my very first time trying to build a kernel from source code. As setup i've a samsung a13 SM-A135M (which is the 4g version of a13 series), this phone by default is forced to work 32bit on a processor and hardware that has the capability to go full 64bit.
The question is:
I've inquiried the correct version and baseband that corresponds to my device, on https://opensource.samsung.com/, and they uploaded the source code of it (the baseband is A135MUBU1AVB5), so with this source code should i be able to build a 64bit version of both kernel and android OS , or this source code only works for 32 bit installations?
Thanks and Regards!
Hi, I just asked a very similar question here: https://androidforums.com/threads/i...this-problem-a13-samsung.1347411/unread?new=1
And someone's reply brought me to your thread. I don't exactly know much about coding but an experienced user said he did some searching, his answer is on my thread. As of now there is no way that he could find to get a 64bit software on the a13, hopefully this changes.
Hi!! thats right, the problem that you have is what has driven this question, although i've the source code for building the OS i'm waiting for someone more experienced to tell me if this source is able to build a 64 bit version of the OS and Kernel for the A13 phone. Hope we find this experienced person

That would be great I think the a13 is great value for the price now we just need to get around the software limitations
