Chapter 2. Kernel Services

The Solaris kernel manages operating system resources and provides facilities to user processes. In this chapter we explore how the kernel implements these services. We begin by discussing the boundary between user programs and kernel mode, then discuss the mechanisms used to switch between user and kernel mode, including system calls, traps, and interrupts.
