然后，手动修改内核源码，你可以参考下面这个 patch:
|
||||
请注意，某些设备的defconfig文件可能在`arch/arm64/configs/设备代号_defconfig`或位于`arch/arm64/configs/vendor/设备代号_defconfig`。在您的defconfig文件中,将 `CONFIG_KSU`设置为`y`以启用KernelSU,或设置为`n`以禁用。比如在某个defconfig中:
|
||||
`arch/arm64/configs/...`
|
||||
```sh
|
||||
+# KernelSU
|
||||
+CONFIG_KSU=y
|
||||
```
|
||||
|
||||
然后，将 KernelSU 调用添加到内核源代码中，这里有几个补丁可以参考：
