Does the Kernel being for Android 11 mean its useless for us? Can Android 12/13 roms not be made with it? I really just wanted working doubletap2wake, would the Android 11 Kernel make that happen? Thank you!

No; sure; works already flawless in PA, but sure why not. There are others problems eg. missing drivers in source and missing devs in group. Fyi: many people using a13 custom rom with a11 stock kernel actually on rn11

nice. they can now close 1k issues regarding spes kernel. hahaha

There are some people fixing the issues with source already!

Oh wow really, tape2wake works great in PA? I have tried almost all roms but PA. Thank you for letting me know, a shame the Kernel is missing drivers and such. I wonder why Xiaomi is trying to make sure the Note 11 is never developed for, it's such a good phone with a custom rom.

Haha I think Pulsar was referring to Xiaomi's github page where there would be like 10 posts a day asking for Spes kernel

tap2wake also works on PixelExperience, FWIW.

EDIT: board_id.h is present in the same directory, not in include/. \

I've tried compiling the kernel from Xiaomi's sources and stumbled across an error about a missing header file:

drivers/misc/st21nfc.c:43:22: fatal error: board_id.h: No such file or directory
 #include <board_id.h>
                      ^
compilation terminated.
make[2]: *** [scripts/Makefile.build:338: drivers/misc/st21nfc.o] Error 1
make[1]: *** [scripts/Makefile.build:642: drivers/misc] Error 2

This file board_id.h does not exist in the include/ folder. Perhaps Xiaomi uploaded incomplete sources?

yes

Much easier to compile this kernel using Clang rather than GCC. Still getting used to it, it's been a good while since my last kernel compile, haha.

Does anyone know how to build a new boot image by hand? I have a working boot.img for PixelExperience and I'd like to replace the kernel with one that I built for testing, but I'm not sure if I should still use mkbootimg like with older Android devices as this is the first time I'll be dealing with a device that uses dtb/dtbo files. Any insights would be welcome.

Not an expert here. What exactly are the benefits of this? What does it mean for custom ROM development?

For one, it is theoretically easier to keep the device up to date without having to wait for Xiaomi's updates. Some changes that come with Android's monthly security patches are made to the kernel, for example, and having the kernel source code means we can apply those patches faster than if we were to wait for updated kernel builds from Xiaomi.

Some ROMs like LineageOS also require kernels to be built from source (i.e., not prebuilt) for a device to be granted official status.

Hello,
Can someone guide me on how to install that kernel on redmi note 11 (Pixel Experience custom os)
Already installed twrp 3.7.0 but gives me some errors all the time like Invalid zip file format!.
I download it as zip from github and put it in twrp folder and install it from there.

Thanks in advance

There's nothing to flash here. Only the link to the kernel source. There's still some work to do for a flashable kernel (compiling eg). Also there are drivers missing in the source it seems. What you tried was flashing the uncompiled kernel source package i guess and that.. doesn't work

 

[jasmin811]

Oh ok,I though it was finished already.
