Английская Википедия:Debugfs
Шаблон:For Шаблон:Lowercase title debugfs is a special file system available in the Linux kernel since version 2.6.10-rc3.[1] It was written by Greg Kroah-Hartman.[2]
debugfs is a simple-to-use RAM-based file system specially designed for debugging purposes. It exists as a simple way for kernel developers to make information available to user space.[3] Unlike Шаблон:Mono, which is only meant for information about a process, or sysfs, which has strict one-value-per-file rules, debugfs has no rules at all. Developers can put any information they want there.[4]
Use
To compile a Linux kernel with the debugfs facility, the Шаблон:Mono option must be set to yes. It is typically mounted at Шаблон:Mono with a command such as:[5]
mount -t debugfs none /sys/kernel/debug
It can be manipulated using several calls from the C header file Шаблон:Mono, which include:
- Шаблон:MonoШаблон:Snd for creating a file in the debug filesystem.
- Шаблон:MonoШаблон:Snd for creating a directory inside the debug filesystem.
- Шаблон:MonoШаблон:Snd for creating a symbolic link inside the debug filesystem.
- Шаблон:MonoШаблон:Snd for removing a debugfs entry from the debug filesystem.
