Write your own kernel module and insert it into running kernel

Post date: January 12, 2009, 08:01 Category: Programming Views: 4520 Comments
Tutorial quote: So, you want to write a kernel module. You know C, you've written a few normal programs to run as processes, and now you want to get to where the real action is, to where a single wild pointer can wipe out your file system and a core dump means a reboot.

kernel Modules are pieces of code that can be loaded and unloaded into the kernel upon demand. They extend the functionality of the kernel without the need to reboot the system. For example, one type of module is the device driver, which allows the kernel to access hardware connected to the system.

Tutorial quote: Kernel 2.6.28 Released

Torvald released the final version of Linux Kernel 2.6.28. It's not a big change since RC 9, but it finally appeared as final after lots of discussion on LKML whether to postpone the release or release earlier and make the merge window longer as the developers goes on long holidays.

Here's some summary of Kernel 2.6.28 (taken from KernelNewbies): Linux 2.6.28 adds the first version of Ext4 as a stable filesystem, the much-expected GPU memory manager which will be the foundation of a renewed graphic stack, support for Ultra Wide Band (Wireless USB, UWB-IP), memory management scalability and performance improvements, a boot tracer, disk shock protection, the phonet network protocol, support of SSD discard requests, transparent proxy support, several new network drivers, controlable IO CPU affinity, high-resolution poll()/select(), support of a minimal "dummy" policy in SELinux, tracing improvements, x86 x2APIC support, a fb driver for VIA UniChrome devices, Mitac Mio A701 ARM-based smartphone support, some new drivers, improved device support, and many other small improvements and fixes.
