没有sysfs / debugfs文件系统的Linux

Question

I need to use a system without any sysfs/debugfs (this is a strong requirement, can't change it).

I need to understand how I can manage to set the Linux without this filesystem.

For example when configuring various omap PM (power management features) I need to set the following:

echo 1 > /dbg/pm_debug/sleep_while_idle

Do you think it is possible to set it as default to 1 for example (I don't need to change the value in runtime) ? How can it be done ?

Answer 1

我发现sysfs / debugfs设置的值实际上已设置为内核中的某些变量，因此，这实际上是在内核中使用predefind（默认）值设置特定变量的问题。
