Wow, keep working on dev so you do have a redmi 3s?? Cause i have a plan to buy redmi 3x in near future, so maybe i can help you testing the kernel

Oh, NO, It's HELL.
If you think it's important to get sourcecode, don't jump to redmi3s/3x yet.
If you insist it, you are wellcome.

I'm not that hurry to get the source code, i can live with miui though, but if there is a faster rom builded from source then i'll move there ??? cause i really need fingerprint on it, and the the design that different from any other redmi 3 varian ???

Very interesting! I've been away from Xiaomi for about 2 years... but decided to get the Redmi 3S as backup phone. Now running some Chinese CM 13 rom, but this looks promising.
Totally forgot about Xiaomi and the trouble surround kernel sources. I remember with the Mi2S we used a kernel build from scratch too for development. But it seems they do release stuff nowadays? Only not directly?

Xiaomi released some source, but redmi 3s doesn't get luck.

Hi, I've used your device source code as base for my own port, but I updated most of the HAL drivers from stock QC files.
But I can't boot. I get stuck with an error "Too many open files". Did you ever had this bug ?

I also did my own kernel based of the LA.UM.5.3_RB1.1 It seam to be the most up to date for MSM8937.

You can have a look at my port here :
Kernel : https://github.com/supercairos/android_kernel_xiaomi_msm8937
Device : https://github.com/supercairos/android_device_xiaomi_land

copy from porting kernel thread:

About LA.UM.5.3-01110-8x37.0:
I just try to find a QAEP release which match the release date of Redmi 3S as much as possible. Nothing more.

About "too many open files":
My repo #deccaf5 (9.21.2016) can boot cm, but it need force reboot several times.
After that commit, the error same as yours. Sorry for my bad.
https://github.com/yangyangnau/andro...ce_xiaomi_land

A few of days ago, I'm try using my kernel and proprietary-files.txt with the repo below.
https://github.com/Silentlys/android_device_xiaomi_land
Clean the fake kernel header tree. Clean the malware (2345 stuff). Clean TWRP stuffs.
No luck. Just get black screen. Can't remember the error messages. Could be "too many open files".
I guess the proprietary-files.txt is a problem.

Thanks!

Might be :)
I will investigate more soon. I've tried to raise the Open file limit but doesn't seams to fix the issue.

About the Kernel Xiaomi based his SW on, it's probably LA.UM.5.1_rb1.4 (not sure what manifest exactly quite hard to test ;) ) as it's the branch that Ardreno was build on (you can check the logs and see that at each app boot). I based mine on the lastest branch that support msm8937_64.

I don't think the kernel version is a big issue, but i will check it.
