Techniques for upgrading and customizing the Linux kernel
KERNEL TECH
Author(s): KLAUS KNOPPER
If you work with third-party hardware drivers, or even if you just need to fix a broken system, someday you might need to upgrade the Linux kernel.
A technical expert will tell you that the kernel is the Linux – the Hardware Abstraction Layer and everything else you see on your screen is mostly application software from the GNU collection. Linux is the operating system core that makes a computer usable in a Unix-like way. On the technical level, a kernel consists of the following basic components:
• support for hardware and corresponding drivers;
• a so-called scheduler, which distributes available computing power (CPU cycles) and hardware resources among application programs, thus allowing the programs to run independently of each other without causing deadlocks or conflicts; • a virtual memory and filesystem manager that makes memory and disk space available to programs.
