Where are the kernel modules in Android?

Kernel modules from the SoC vendor that are required for full Android or Charger modes should be located in /vendor/lib/modules . If an ODM partition exists, kernel modules from the ODM that are required for full Android or Charger modes should be located in /odm/lib/modules .

What is Android GKI?

The Generic Kernel Image (GKI) project addresses kernel fragmentation by unifying the core kernel and moving SoC and board support out of the core kernel into loadable modules. The GKI kernel presents a stable Kernel Module Interface (KMI) for kernel modules, so modules and kernel can be updated independently.

How do I add a new kernel module?

Loading a Module

  1. To load a kernel module, run modprobe module_name as root .
  2. By default, modprobe attempts to load the module from /lib/modules/kernel_version/kernel/drivers/ .
  3. Some modules have dependencies, which are other kernel modules that must be loaded before the module in question can be loaded.
