So, we already have kernel sources from the Vernee Apollo Lite, and the Vernee Thor Lite.
I've found two more sources that may possibly have a slight chance of being better.
It's worth noting that Meizu have a page about the GPL license (https://translate.google.com.au/tra...el.meizu.com/projects.html&edit-text=&act=url), and they'll probably soon release the kernel for the Pro 6 phone, which actually has a Helio x25 proccesor and simmilar hardware. Keep an eye out for it: https://github.com/meizuosc?tab=repositories
Meizu MX6 (Helio x20) source: https://github.com/meizuosc/m685
A quick google search gave me a github page that looks like it's just the linux kernel, for the Helio x20, with no extra drivers included, so this probably isn't so useful. It is version 4.7 at the time of writing, though.
https://github.com/helio-x20/linux
On a side note, Team Emotroid have made a modified version of MIUI (https://forum.xda-developers.com/redmi-pro/development/xiaomotion-red-mi-pro-rom-control-t3600811). Since they are distributing the binary, they are also obligated to supply kernel source. Has anyone tried contacting them? Here's their github: https://github.com/Emotroid-Team
Kernel source has to be the one for the Redmi Pro and not from a similar phone because there is no phone with exactly the same components as the Redmi Pro. Those phones have the same CPU but not the same components so we will have to wait until Xiaomi releases the sources (if they release them )
Also, it is possible to modify MIUI without the kernel source and that is what they did. There is no need to use kernel sources if the precompiled kernel is already working well in MIUI 8

I have already posted this request in the "Support for new device" thread several times but no result
I just want to say why no forum is made for Xiaomi Redmi 1S? Some say due to lack of kernel source and development...
Well, Redmi 1S have a working CM11, Mokee and newly compiled AOSPA too!!
Talking about kernel source,
I agree we dont have kernel source now, but in future it will get it, and its for sure..
And if you are not making Xiaomi Redmi 1S's forum due to kernel sources, then there are other phones too which don't have kernel sources, yet, they have a forum on XDA (Many MTK chipset devices and also Xiaomi Mi3 and Mi4!)
I hope XDA mods see this request and get it worked..
Yes this is so true...
AGREED
Up this post for admin to see
I, on behalf of the owners of the Karbonn Titanium S5 Plus device, based on the Mediatek MT6582 chipset, need some help in building a kernel source (not a kernel from source) for this device. I have a few fully working custom ROMs, a Github Account, some forked repositories of other devices having the same chipset but minorly-different hardware, and some time. What do I have to do to get to building a kernel source for this device?
It is a dual-sim device, based on the Mediatek MT6582 SoC, having a prebuilt kernel version 3.4.5, with no kernel sources even for its clone, running Android Jelly Bean 4.2.2 . @superdragonpt had created some new kernels for some devices(eg. the Wiko Darkmoon, MT6582, he created a new kernel source and a new kernel) having no previous kernel sources, how can I do the same for my device?
The Android One devices (Indian) are based on the same chipset, and have the same features. But, the difference is that they have a smaller 5MP rear camera and a locked bootloader, while ours has a 8MP rear camera and an unlocked bootloader. Can their sources be used for my device?
Also, after creating a Kernel source, how can I create an AOSP source for this device? Please help me out with this.
Hi there,
All things about your device is in this thread:
[ROMs and Recoveries] Karbonn Titanium S5 Plus/ S5 + - All Things And Dev.
Take a close look there and see if you find an answer there.
Good luck
I know, I started that thread.
It contains many Roms for my device, but there are no updates for them because it does not have a kernel source. There are no new kernels for the device because a kernel source was not released by the company. So, I asked it here.
I forked the kernel source from another device having the same soc, but I wanted to know how to create one specifically for my device.
One more thing. How do you build a kernel from a kernel source? Please help me out. Thanks in advance.
You can learn more about kernel development here:
[GUIDE] Build Your Own Android Kernel{Easiest and Fastest Way] [Using The NDK]
[TUTORIAL][VIDEO]Build your own Android kernel
I suggest reading a couple of the relevant kernel tutorials found here: http://forum.xda-developers.com/chef-central/android
Good luck

I have decided to stick with MIUI to source code becomes available to developers.
While I admire custom ROM development so far: there seem to be a lot of bugs an limitations that developers are all saying are the result of not having source code.
Does anyone have a probable date on the release of source code for the Poco X3 an X3 NFC?
Source code may help with GSI an F2FS development for our device for instance?
Xiaomi still doesnt release the kernel source code for our phone. With the source the devs will can do more things for development such more stable roms and kernels. The phone released at May 09 2020 but xiaomi doesnt release it. They relase the source even for Mi 11 which dont even is at the market yet but for us not.
So we try to spam them in github to show them that we want it. Toco is a large community. So please make a post here to request to release it

Done my part...
Let's hope for the best
this really needs to happen. i buy Xiaomi phone to be free with the software, i want custom Roms and stuff for it, please Xiaomi
After reading about the fast kernel source release for the Xiaomi 12 and Xiaomi 12 Pro one could think that xiaomi did a good job at complying with the GPL v2 license and providing useful sources for developers of custom kernels. But appearances are deceiving: The provided kernel sources are incomplete and partially broken.
The most important issues are that xiaomi pushed incomplete devicetree sources which are neither provided by qualcomm anymore unfortunately and the touchscreen drivers are really out of date which leads to broken double tap to wake and under display fingerprint sensor. Additionally building the kernel isn't as trivial as it sounds anymore since many kernel modules are built outside of the kernel tree now.
During the past days i have spent some time on getting a source built kernel including modules and devicetree running on Xiaomi 12.
I have sucessfully booted the kernel and uploaded this work to github.com/xiaomi-sm8450-kernel.
Using this manifest one is able to compile the OSS kernel for Xiaomi 12 and Xiaomi 12 Pro.
I hope that this can help other developers working on the Xiaomi 12 and Xiaomi 12 Pro!
For instructions to build the kernel and more details about missing sources please refer to the manifest on github.
Note that double tap to wake and fingerprint sensor don't work as is on the stock ROM.
Also note that the OSS display-devictree for Xiaomi 12 Pro is missing the configurations for some referesh rates which were supported on MIUI. This could be dumped and included from the stock dtbo.img with some effort.
If you encounter issues with this OSS kernel feel free to ask me and i will give my best to help.
To finish this thread i want to draw further attention to the fact that this is not a one-time issue with the OSS kernels for Xiaomi devices and the situation seems to get even worse. The newer Redmi K50 gaming got kernel sources which don't include any external respositories, as in no techpack drivers and no devicetree sources at all. The new Xiaomi 12S series still has not seen any open source kernel release.
I hope this project helps to set a better starting point than the xiaomi oss release to other developers for the Xiaomi 12 and Xiaomi 12 Pro.
Thanks for thus clarification Arian. Sad story....To be continued... Quo Vadis Xiaomi?
ti think the xiaomi 12 has suffered a performance squeeze... this is not because of the heat.... i have tried thermal unlocking and overclocking the CPU GPU and updating the driver 617 the result shows the real performance is vastly different many
Can you tell me which version of clang can be used to build the kernel from the sources for lineageos 20? And which commands to use? I would like to build a kernel for Kali Nethunter, but when using any of the defconfig I get compilation errors
Can you explain how to flash built kernel..? I built the kernel and I get the kenrel image but I don't know how to flash it to the device...
Would you know if this is also the case for Mi11 Ultra tree?
The OSS for the 12S and 12S Pro has just been released recently if anyone is interested in looking at it:
GitHub - MiCode/Xiaomi_Kernel_OpenSource at mayfly-s-oss
Xiaomi Mobile Phone Kernel OpenSource. Contribute to MiCode/Xiaomi_Kernel_OpenSource development by creating an account on GitHub.
github.com
I would be interested to hear if the kernel source for the 12S family is also incomplete, like the regular Xiaomi 12 series

You need to pack the boot, vendor_boot, vendor_dlkm and dtbo images, the easiest way is to do that within the LineageOS tree.

Yes, unfortunately this devices source situation is even worse. On all the recent releases xiaomi did not release the audio, display and camera drivers. The released touchscreen driver does not compile either, though i fixed that by guessing and the driver works now: https://github.com/xiaomi-sm8450-ke...3b9d0f69ecd2ba01674a0dc29cfdc86782bb7c9d6c3da
