OpenBSD platforms

This document is meant to complement the OpenBSD's Hardware Plaforms page.

When possible, the platform names and release numbers are linked to their corresponding web page on the OpenBSD web site.

By release

This table helps you see the evolution of the various hardware platforms over all the CD set and FTP release produced by the OpenBSD project over the years.

Platforms marked with an * are only available via FTP. They were not part of the CD set for their release.

The OpenBSD mirror www.mirrorservice.org and ftp.lysator.liu.se have all the releases since the beginning. For recent releases, you may use any OpenBSD mirror.

Notes:
1. OpenBSD supports the 2 latest release and do 2 releases a year. Giving you at most 1.5 year of support for the newest one at release date.
2. OpenBSD self-host all their platforms. Cross-compiling is reserved for jump-starting new archs. On one side, you get a compiler chain that is well tested, debugged and works. But without a modern compiler, a lots of ports aren't available. These archs do not have the CPU power, memory or simply upstream supports by clang/gcc to move to a modern tool chain.
3. Estimates. Might be last time the hardware was sold or last time a major CPU release was made.

By CPU architecture

This table is based on the MACHINE and MACHINE_ARCH #define in the various /usr/src/sys/arch/*/include/param.h files.

It only contains the platforms still in OpenBSD's current CVS tree.
