## Features

1. Kernel-based `su` and root access management.
2. Module system based on [OverlayFS](https://en.wikipedia.org/wiki/OverlayFS).
3. [App Profile](https://kernelsu.org/guide/app-profile.html): Lock up the root power in a cage.

## Compatibility State

KernelSU officially supports Android GKI 2.0 devices (kernel 5.10+). Older kernels (4.14+) are also compatible, but the kernel will have to be built manually.

With this, WSA, ChromeOS, and container-based Android are all supported.

Currently, only `arm64-v8a` and `x86_64` are supported.
