![]() Glibc does not seem to provide a C wrapper for them, so we just create our own with syscall. The param_values argument is as for init_module().įinit is newer and was added only in v3.8. It is useful when the authenticity of a kernel module can be determined from its location in the filesystem in cases where that is possible, the overhead of using cryptographically signed modules to determine the authenticity of a module can be avoided. The finit_module() system call is like init_module(), but reads the module to be loaded from the file descriptor fd. The Linux kernel offers two system calls for module insertion: I begin with a straightforward Hello World loadable kernel module (LKM) and work towards developing a module that can control GPIOs on an embedded Linux device (such as the BeagleBone) through the use of IRQs. ![]() obj-m + mhello.o hello-objs : mhello. In this series of articles I describe how you can write a Linux kernel module for an embedded Linux device. We use the init_module / finit_module and remove_module Linux system calls.
