In our previous installment, the author introduced methods for accessing peripherals from user space in Linux. In this installment, Abbott describes kernel modules and device drivers followed by a ...

This includes such things as whenever an inode is accessed, a module is loaded or a task is created. As of the 2.5.31 kernel, there were 88 different function pointers needed. The majority of these ...

Although Linux does not (yet) support this binary format, the good news is that you can learn how to write kernel modules by implementing COM support for the Linux kernel.

The Linux kernel is a monolithic kernel. It’s mainly one large program, but it closely interacts with other, distinct, programs such as drivers and kernel modules.

When you program in the kernel, there is no operating system to step in and safely stop your code from running and tell you that you have a problem. The Linux kernel is pretty nice to its own code.

The kernel, however, including modules, has no such restriction. That can make debugging modules tricky because you can easily bring the system to its knees.

Programmers had already been experimenting with earlier versions of the language as an option for kernel module programming, with a proof of concept developed in 2013.

LKRG kernel modules are currently available for main Linux distros such as RHEL7, OpenVZ 7, Virtuozzo 7, and Ubuntu 16.04 to latest mainlines. Not a perfect solution ...
