In summary the Linux Kernel is the interface between the operating system and your computer hardware. It is the core of any computer allowing the operating system to control a number of different functions and is the most vital part of any operating system - without which your computer would not operate.

DKMS (Dynamic Kernel Module Support) is a framework where device driver source can reside outside the kernel source tree so that it is very easy to rebuild modules as you upgrade kernels.

Kernel as hypervisor: Andrea Arcangeli

A Linux kernel developer explains the key overlaps between the hypervisor and the OS kernel. The KVM architecture uses Linux as both, which puts new capabilities at the hypervisor's disposal.

The Linux kernel is an interesting project to study for a number of reasons. It is one of the largest individual components on almost any Linux system. It also features one of the fastest-moving development processes and involves more developers than any other open source project. This web page, Linux Kernel Development (April 2008),  looks at how that process works, focusing on nearly three years of kernel history as represented by the 2.6.11 through 2.6.24 releases.

Concurrency is one of the most important concepts which can lead to errors in a system that are hard to find. With the inherent support for SMP and preemptive scheduling in Linux, concurrency is a critical factor which has to be considered while designing kernel modules or device drivers. Avoiding race conditions can be a difficult task. Linux, as in any other OS, provides many synchronization primitives to manage concurrency. Semaphores and Mutexes are part of them.

In the last two months, Linux has made an enormous step forward in terms of power consumption and battery life. Linux kernel community developers such as Thomas Gleixner and Ingo Molnar and various Intel developers joined hands in developing a set of patches to push Linux to the next level with the Tickless Idle feature and a series of follow on developments that cash in the potential of the tickless core infrastructure.
