-# Tracepoint Hook Integration
-
-## Introduction
-
-Since commit [49b01aad](https://github.com/SukiSU-Ultra/SukiSU-Ultra/commit/49b01aad74bcca6dba5a8a2e053bb54b648eb124), SukiSU has introduced Tracepoint Hook
-
-This Hook theoretically has lower performance overhead compared to Kprobes Hook, but is inferior to Manual Hook / Syscall Hook
-
-> [!NOTE]
-> This tutorial references the syscall hook v1.4 version from [backslashxx/KernelSU#5](https://github.com/backslashxx/KernelSU/issues/5), as well as the original KernelSU's [Manual Hook](https://kernelsu.org/guide/how-to-integrate-for-non-gki.html#manually-modify-the-kernel-source)
