Linux tries to maintain a neat
distinction between hardware-dependent and hardware-independent
source code. To that end, both the
arch
and the include
directories include nine subdirectories that correspond to the nine
hardware platforms supported. The standard names of the
platforms
are:
- alpha
Hewlett-Packard’s Alpha workstations
- arm
ARM processor-based computers and embedded devices
- cris
“Code Reduced Instruction Set” CPUs used by Axis in its thin-servers, such as web cameras or development boards
- i386
IBM-compatible personal computers based on 80 × 86 microprocessors
- ia64
Workstations based on Intel 64-bit Itanium microprocessor
- m68k
Personal computers based on Motorola MC680 × 0 microprocessors
- mips
Workstations based on MIPS microprocessors
- mips64
Workstations based on 64-bit MIPS microprocessors
- parisc
Workstations based on Hewlett Packard HP 9000 PA-RISC microprocessors
- ppc
Workstations based on Motorola-IBM PowerPC microprocessors
- s390
32-bit IBM ESA/390 and zSeries mainframes
- s390 x
IBM 64-bit zSeries servers
- sh
SuperH embedded computers developed jointly by Hitachi and STMicroelectronics
- sparc
Workstations based on Sun Microsystems SPARC microprocessors
- sparc64
Workstations based on Sun Microsystems 64-bit Ultra SPARC microprocessors
