What's KernelSU?

KernelSU is a root solution for Android GKI devices, it works in kernel mode and grant root permission to userspace application directly in kernel space.

The main feature of KernelSU is it is Kernel-based. KernelSU works in kernel mode, so it can provide kernel interface we never had before. For example, we can add hardware breakpoint to any process in kernel mode; We can access physical memory of any process without anybody being aware of; We can intercept any syscall in kernel space; etc.

And also, KernelSU provides a module system via overlayfs, which allows you to load your custom plugin into system. It also provides a mechanism to modify files in /system partition.
