Linux hardware dependency

[From: an in-depth understanding of Linux kernel]

Linux tries to keep a clear line between hardware-independent source code and hardware-related source code. To achieve this, the arch and include directories contain 23 sub-directories to correspond to different hardware platforms supported by Linux. The standard names of these platforms are as follows:

Alpha

HP's Alpha workstation was first owned by digital, and later belongs to Compaq, which is no longer produced.

Arm, arm26

ARM-based computers (such as PDAs) and embedded devices.

Cris

Axis uses the "Code reduced instruction set" CPU in its thin server, which is used in such a web camera or development motherboard.

Frv

The embedded system is based on the microprocessor of the Fujitsu FR-V system.

H8300

Hitachi H8/300 and h8s 8-bit and 16-bit Proteus microprocessor.

I386

80x86 microprocessor-based IBM compatible PC.

IA64

Workstation based on 64-bit itanium microprocessor.

M32r

A Computer Based on the Renesas m32r series microprocessor.

M68k, m68knommu

PC based on Motorola mc680x0 microprocessor.

MIPs

MIPs microprocessor-based workstations, such as those sold by Silicon Graphics.

Parisc

Workstation based on HP 9000 PA-RISC microprocessor.

PPC, ppc64

Based on mongolar-IBM PowerPC 32-bit and 64-bit microprocessor.

S390

Ibm esa/390 and zseries mainframe.

Sh, sh64

Embedded Systems Based on the superh microprocessor jointly developed by Hitachi and STMicroelectronics.

ISCSI, sparc64

Workstation based on Sun's iSCSI and 64-bit ultra-iSCSI microprocessor.

Um

Linux in user mode-a virtual platform that allows developers to run the kernel in user mode.

V850

The NEC v850 microprocessor integrates a 32-bit Proteus Core Based on the Harvard architecture.

X86_64

AMD-based 64-bit microprocessor workstations, such as athlon and opteron, and Intel-based ia32e/em64t 64-bit microprocessor workstations.
