<toc-add-entry name="about">Overview</toc-add-entry>
<p>The MIPS port is actually two ports, <em>debian-mips</em> and
<em>debian-mipsel</em>. They differ in the <a
href="http://foldoc.org/endian">endianness</a>
of the binaries. MIPS CPUs are able to run at both endiannesses, but
since that's normally not changeable in software, we need to have both
architectures. SGI machines run in <a
href="http://foldoc.org/big-endian">big-endian</a>
mode (debian-mips) while the Loongson 3 machines run in
<a
href="http://foldoc.org/little-endian">little-endian</a>
mode (debian-mipsel). Some boards, such as Broadcom's BCM91250A evaluation
board (aka SWARM) can run in both modes, selectable by a switch on the board.
Some Cavium Octeon based machines can switch between both modes in the
bootloader.</p>
<p>Given most MIPS machines have 64-bit CPUs, a <em>debian-mips64el</em> port
is currently in development and might be released with Debian GNU/Linux 9.</p>
<toc-add-entry name="status">Current Status</toc-add-entry>
<p>Debian GNU/Linux <current_release_jessie> supports the following machines:</p>
<ul>
<li>SGI Indy with R4x00 and R5000 CPUs, and Indigo2 with R4400 CPU (IP22).</li>
<li>SGI O2 with R5000, R5200 and RM7000 CPU (IP32).</li>
<li>Broadcom BCM91250A (SWARM) evaluation board (big and little-endian).</li>
<li>MIPS Malta boards (big and little-endian, 32 and 64-bit).</li>
<li>Loongson 2e and 2f machines, including the Yeelong laptop (little-endian).</li>
<li>Loongson 3 machines (little-endian).</li>
<li>Cavium Octeon (big-endian).</li>
</ul>
<p>In addition to the above machines, it is possible to use Debian on a lot more
machines provided that a non-Debian kernel is used. This is for example the
case of the MIPS Creator Ci20 development board.</p>

<toc-add-entry name="availablehw">Available Hardware for Debian Developers</toc-add-entry>
<p>Two machines are made available to Debian developers for MIPS porting
work: etler.debian.org (mipsel/mips64el) and minkus.debian.org (mips).
The machines have development chroot environments which you can access
with <em>schroot</em>. Please see the
<a href = "https://db.debian.org/machines.cgi"> machine database</a> for more
information about these machines.</p>
