The shell’s use of system calls illustrates how carefully they have been designed. The shell is an ordinary program that reads commands from the user and executes them. The

pdos.csail.mit.eduxv6 kernel provides a subset of the services and system calls that Unix kernels traditionally offer. Figure 1.2 lists all of xv6’s system calls. The rest of this chapter outlines xv6’s services—processes, memory, file descriptors, pipes, and a file system—and illustrates them with code snippets and discussions of how the shell, Unix’s

PC Assembly Lanugage - Distributed operating system
pdos.csail.mit.eduOther PC assembly language books still teach how to program the 8086 processor that the original PC used in 1980! The 8086 processor only supported real mode. In this mode, any program may address any memory or device in the computer. This mode is not suitable for a secure, multitasking operating system. This book instead
PC Assembly Lanugage - Distributed operating system
pdos.csail.mit.eduOther PC assembly language books still teach how to program the 8086 processor that the original PC used in 1980! This book instead discusses how to program the 80386 and later processors in protected mode (the mode that Windows runs in). There are several reasons to do this: 1. It is easier to program in protected mode than in the 8086 real mode
