NetBSD calls a supported architecture a 'port'. Most ports run on generic hardware and emulators, although some commercial hardware also exists. The NetBSD Ports History page details the inclusion date for each port.

Ports are classified into three 'tiers' based on the current importance of the architecture and the level of community activity. Summarizing, the tiers can be viewed to represent ports that NetBSD will support, ports that NetBSD does its best to support, and ports which may be desupported soon. The tier for each port may change over time and is decided by based on input from users and developers.

Tier I: Focus -- support is part of NetBSD's strategy

Focus ports are the architectures that NetBSD targets as part of its strategy.
The platforms consist of modern server, embedded and desktop architectures.

The guidelines are as follows:

Currently there are 8 ports with Tier I status. They are:

Port CPU Machines Latest Release
amd64 x86_64 64-bit x86-family machines with AMD and Intel CPUs 7.0
evbarm arm ARM evaluation boards 7.0

sparc64 sparc Sun UltraSPARC (64-bit) 7.0
xen i386, x86_64 Xen Virtual Machine Monitor 7.0

Tier II: Organic -- evolving at its own pace

Organic ports are highly valued by the NetBSD project, but their development is not as tightly mandated as that of the focus ports. Generally speaking, the hardware platforms of organic ports have lost their industrial relevance, or there is not enough community activity for the port to make it to the first tier. The guidelines are as follows:

Currently there are 49 ports with Tier II status. They are:

Tier III: Life Support -- severely incapacitated or broken

Ports are moved to life support if they no longer function. The reasons can range from lack of community interest to the hardware becoming so rare that it is simply not available any more. If ports in life support are not shown to be working within a reasonable timeframe, they will be moved to the Attic. The guidelines are as follows:

Currently there is 1 port with Tier III status. It is:

Port CPU Machines
acorn26 arm Acorn Archimedes, A-series and R-series systems

Ports by CPU architectures

This table contains the same set of ports as in the above list, but ordered by MACHINE_ARCH CPU architecture value (returned by 'uname -p') and showing a total of 16 CPU types. Machines of the same MACHINE_ARCH share the same userland binaries (with a few device specific exceptions). Both big endian (eb) and little endian (el) MIPS and SH3 ports are supported.
