[[!meta title="Platforms supported by NetBSD"]]
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 <core@NetBSD.org> 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.<br />
The platforms consist of modern server, embedded and desktop architectures.
The guidelines are as follows:
* Machine independent (MI) changes should benefit these ports.
* MI changes must be tested on at least one of these ports.
* It is the developer's responsibility to implement machine dependent (MD) support necessary for changes, fix build problems and aid in debugging with any platform-specific problems.
* Even within a port, common sense should be used (cf. the i386 port which still supports 486).
* Regressions in the automated NetBSD test suite (/usr/tests) are not allowed.
Currently there are 8 ports with Tier I status. They are:
Port |CPU |Machines
[[amd64]] |x86_64 |64-bit x86-family machines with AMD and Intel CPUs
[[evbarm]] |arm |ARM evaluation boards
[[evbmips]] |mips |MIPS-based evaluation boards
[[evbppc]] |powerpc |PowerPC-based evaluation boards
[[hpcarm]] |arm |StrongARM based Windows CE PDA machines
[[i386]] |i386 |32-bit x86-family generic machines ("PC clones")
[[sparc64]] |sparc |Sun UltraSPARC (64-bit)
[[xen]] |i386, x86_64 |Xen Virtual Machine Monitor
#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:
* Generally speaking, the port boots and works, but keeping it working is the responsibility of the user community. This includes, but is not limited to, kernel changes and toolchain upgrades.
* Developers committing MI changes are still encouraged to keep ports up-to-date when it can be easily done.
* MI architecture decisions may penalize organic ports if there is a benefit for focus ports.
* If the port is not working at release time, a release is done without the port and the port is moved down to the life support tier.

#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:
* Organic ports get moved here if they do not complete a build for 6 months or are otherwise suspected to be broken.
* It is the responsibility of the users of an organic port to show it is working, not the other way around.
* Movement to life support causes a mail to be sent out to the port mailing list and the portmaster.
* Port will be bumped up to organic when it is shown to be working.
* If the port is not reported fixed within the next 6-12 months, it will be moved to the Attic.
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.
