Hi, can any1 point me trough the process of compiling kernel for this rom?
Hey all who can help me here ?
My question is how to synchronize the kernel threads execution in cleanup routine?
And how I can freeze the entire kernel?
My question is, how?

no idea why it doesnt generate
Abdul7852 2022-07-28 22:55:04
apt-get install linux-headers-generic
Abdul7852 2022-07-28 22:55:06
Try
PiotrBurdzinski 2022-07-28 22:55:45
nope
Abdul7852 2022-07-28 22:57:41
Check the .conf file ig or copy pasta older autoconf

My kernel is not using little cores, only big cores for some reason
Aflaungos 2022-07-29 17:25:10
Being 8 cores, with 4 big and 4 little, usage on little cores stays 0 and reaches only 2 3%

Uh guys
fatal error: ‘generated/autoconf.h’ file not found

Same error here
Can anyone help?

Im trying to add 8188eus driver to kernel, link to driver:
https://github.com/kimocoder/realtek_rtwifi#howto-implement-this-driver-into-android-kernel-nethunter

What i have already tried:

get boot.img
unpacked it
compiled kernel from below this link with new 8188eus drivers
https://github.com/MiCode/Xiaomi_Kernel_OpenSource/tree/begonia-r-oss
repacked boot.img with new kernel
flashed it to boot partition
phone turns on > phone wifi isnt working > external wifi adapter isnt working

I also tried to compile kernel from above link without any modifications(adding drivers ) and phone wifi still doesn’t work

maybe this kernel have incomplete/broken sources/drivers

You alternative is use a another custom kernel, and try again

I’m going to develop a kernel module which will patch kernel functions in runtime with a custom trampoline in prologue. Sort of ftrace-like functionality, but much more flexible, versatile and powerful. My question is how to synchronize the kernel threads execution in cleanup routine? I want to return to the original function execution after each custom trampoline code execution. Will spinlock be a good solution? Considering very small critical section:
1) Acquire a spinlock
2) Write a custom cleanup routine (just 2 instructions) to RWX memory and execute it
3) Unlock a spinlock and return to the original function
s3gfau1t1337 2022-08-01 13:14:04
And how I can freeze the entire kernel? I need to do that in order to inject call instruction to a custom trampoline in each kernel function prologue, and then “resume” the entire kernel

B,,,,.

I just read “I’m going to do some cool shit. My question is, how?”
Zildj1an 2022-08-01 21:54:43
I also don’t see why do you need any synchronization, a trampoline-like hook in the prologue would be sequential with whatever place you take it to
Zildj1an 2022-08-01 22:00:01
not to mention you can’t use spinlock to patch functions that run with interrupts disabled
