I compiled custom kernel with couple extra drivers and due they had conflicts when I tried to add them as built-in drivers to kernel, I had to compile them as separate modules. I signed the modules, insmodded them and they work well. No conflicts. The problem is that I neither have modules directory in /system/lib folder nor /vendor/lib. I tried to create them manually but even after creation, it didn't load after reboot. Now questions:

Where can I put kernel modules if I don't have these folders?
How can I make it without modifying system? I want to ship the kernel as only 1 AnyKernel3 zip.

Please, if you at least know answer to one of these questions, respond either as answer or comment.

I feel that this is about programming/development, so off-topic here. – Rohit Gupta Jul 19 '23 at 10:59
Put them in /system/lib/modules/ or /vendor/lib/modules/. You need to load them using a boot script. They are not auto-loaded. To avoid modifying /system, use Magisk modules. – Irfan Latif Jul 19 '23 at 16:21
@IrfanLatif, I can remount /vendor partition as rw and then add those modules and folders. Issue is at loading them. How can I load them? – Running Child Jul 19 '23 at 19:07
My init binary is compiled code. Where else can I add insmod /vendor/lib/modules/module.ko line? – Running Child Jul 19 '23 at 19:08
See Magisk Boot Scripts and How to run an executable on boot?. – Irfan Latif Jul 20 '23 at 16:13
Thanks @IrfanLatif . I will take a look at them – Running Child Jul 21 '23 at 07:44
