Some Generic Kernel Techniques

The discussion of operating system internals presents many challenges and opportunities to an author. Our approach is to discuss each area of the kernel, consider the challenges faced by kernel designers, and then explore the path taken toward the final solution implemented in the HP-UX code.

Before we talk about HP-UX specifics, let's discuss some generic challenges faced by kernel designers. As with any programming assignment, there are frequently many different ways to approach and solve a problem. Sometimes the decision is based on the programmer's past experience, and sometimes it is dictated by the specific requirements of each kernel design feature. As an operating system matures, these individual point solutions ...
