<toc-add-entry name="intro">Introduction</toc-add-entry>
<p>
 As most of you know, <a href="https://www.kernel.org/">Linux</a>
 is just a kernel.  And, for a long time,
 the Linux kernel ran only on the Intel x86 series of machines, from
 the 386 up.
</p>
<p>
 However, this is no longer true, by any means.  The Linux kernel has
 now been ported to a large, and growing, list of architectures.
 Following close behind, we have ported the Debian distribution to
 these architectures.  In general, this is a process with a sticky
 start (as we get libc and the dynamic linker working smoothly), and
 then a relatively routine, if lengthy job, of attempting to recompile
 all our packages under the new architectures.
</p>
<p>
 Debian is an operating system (OS), not a kernel (actually, it is more
 than an OS since it includes thousands of application programs). Accordingly,
 while most Debian ports are based on Linux, there also are ports based on the
 FreeBSD, NetBSD and Hurd kernels.
</p>

<div class="important">
<p>
 This is a page in progress.  Not all ports have
 pages yet, and most of them are on external sites.  We are working on
 collecting information on all ports, to be mirrored along with the Debian
 website.
 More ports may be <a href="https://wiki.debian.org/CategoryPorts">listed</a> on the wiki.

<toc-add-entry name="portlist-released">List of official ports</toc-add-entry>

<p>
These ports are the officially supported architectures by the Debian project,
and either part of an official release or to be part of an upcoming one.

<toc-add-entry name="portlist-other">List of other ports</toc-add-entry>

<p>
These ports are either work in progress efforts that intend to eventually
be promoted into officially released architectures, ports that were once
officially supported but stopped being released because failed the release
qualification or had limited developer interest, or ports that are no
longer worked on and are listed for historical interest.
</p>

<p>
These ports, when they are still actively maintained, are available on
the <url "https://www.ports.debian.org/"> infrastructure.
</p>

<div class="tip">
<p>
 There are non-official installation images available for some of the following ports in
 <url "https://cdimage.debian.org/cdimage/ports"/>.
 Those images are maintained by the corresponding Debian Port Teams.
