Why is the Linux kernel written in C/assembly?
• (ADB) For many reasons, some practical, others theoretical. The practical reasons first: when Linus began writing Linux, what he had available was a 386, Minix (a minimal OS designed by Andrew Tanenbaum for OS design teaching purposes) and gcc. The theoretical reasons: some small parts of any OS kernel will always be written in assembly language, because they are too dependent on the hardware to be coded in C; for example, CPU and virtual memory setup. Or because we are dealing with very short routines that must be implemented in the fastest possible code e.g. the stubs for the “top half” interrupt handlers. WRT C, OS designers (since Thompson and Ritchie first wrote UNIX) have traditionally used C to implement as many OS kernel routines as possible. In this sense C can be considered the “canonical” language for OS kernel implementation, and particularly for UNIX variants.
