I have then tried to implement methods similar to those explain here and here. The Linux kernel exists as a file named: vmlinuz When a user interacts with his computer, he interacts directly with the kernel of the computer's operating system. In my governor I am attempting to open the files into file pointers that I will then keep and read every governor tick. How are '/dev' Linux files created Asked 7 years, 9 months ago Modified 2 years, 1 month ago Viewed 65k times 128 There are special files in Linux that are not really files. I am writing a cpufreq power governor that is trying to create a FSM from system information (hence need for file reading). But it is for a dirty, quick proof of concept for some research work. I need to read out device and sysfs values for power sensors and GPU for my specific android board (Odroid XU3) running 3.10.9 kernel. Reading file in the Linux Kernel Ask Question Asked 4 years, 9 months ago Modified 4 years, 9 months ago Viewed 2k times 1 so before I get the barrage of 'you shouldn't be doing that', I know I shouldn't. I have done a lot of googling and have come up short unfortunately. Where possible, you get links to other IBM resources to help you dig deeper. In this article, you explore the general structure of the Linux kernel and get to know its major subsystems and core interfaces. My knowledge of this area is very small as I have only ever used sysfs to expose values I generate within my modules, any pointers in the right direction would be greatly appreciated. The Linux kernel is the core of a large and complex operating system, and while it\\'s huge, it is well organized in terms of subsystems and layers. Linux was initially distributed as source code only, and later as a pair of downloadable floppy disk images: one bootable and containing the Linux kernel itself, and the other with a set of GNU utilities and tools for setting up a file system. FAT, ext4, btrfs, ntfs) and on one running system we can have multiple instances of the same filesystem type in use. Linus Torvalds developed the Linux kernel and distributed its first version, 0.01, in 1991. There are many types of filesystems (e.g. If the concept works I will look at proper exporting of information to my module. A fileystem is a way to organize files and directories on storage devices such as hard disks, SSDs or flash memory. So before I get the barrage of "you shouldn't be doing that", I know I shouldn't. Services such as SSH pull their settings from configuration files during the startup process.
