<p>This document contains the hardware compatibility notes
for FreeBSD 5.0-CURRENT on the UltraSPARC hardware platform
(also referred to as FreeBSD/sparc64 5.0-CURRENT). It lists
devices known to work on this platform, as well as some
notes on boot-time kernel customization that may be useful
when attempting to configure support for new devices.</p>
<div class="NOTE">

<p><b>Note:</b> This document includes information
specific to the UltraSPARC hardware platform. Versions
of the hardware compatibility notes for other
architectures will differ in some details.</p>

<h2 class="SECT2"><a name="AEN18">2.1 Overview</a></h2>
<p>This document tries to provide a starting point for
those who want to run FreeBSD on an UltraSPARC-based
machine. It is aimed at providing background information
on the various hardware designs. It is not a replacement
for the systems manuals.</p>
<p>The information is structured as follows:</p>
<ul>
<li>
<p>General hardware requirements to run FreeBSD on
sparc64.</p>
</li>
<li>
<p>System specific information for each of the
systems/boards supported by FreeBSD.</p>
</li>
<li>
<p>Information on expansion boards for FreeBSD,
including things that differ from what is in the
generic supported hardware list.</p>
</li>
</ul>

<h2 class="SECT2"><a name="AEN29">2.2 In general, what do
you need to run FreeBSD on a sparc64</a></h2>
<p>FreeBSD/sparc64 requires an UltraSPARC system.
Currently, the newer PCI-based systems are supported
better than the older SBus based systems. The following
systems are known to work to varying degrees:</p>
<ul>
<li>
<p>Sun Ultra 1 workstations</p>
</li>
<li>
<p>Sun Ultra 2 workstations</p>
</li>
<li>
<p>Sun Ultra 5 workstations</p>
</li>
<li>
<p>Sun Ultra 10 workstations</p>
</li>
<li>
<p>Sun Ultra 30 workstations</p>
</li>
<li>
<p>Sun Ultra 60 workstations</p>
</li>
<li>
<p>Sun Blade 100 workstations</p>
</li>
<li>
<p>Sun Netra t1 series servers</p>
</li>
<li>
<p>Sun Enterprise 220R servers</p>
</li>
<li>
<p>Sun Enterprise 250 servers</p>
</li>
<li>
<p>Sun Enterprise 420R servers</p>
</li>
</ul>
<p>Ultra 80 and Blade 1000 are expected to work, maybe
with minor modifications. SMP is supported on Ultra 2 and
60 workstations and Enterprise 220R, 250 and 420R
servers.</p>

<h2 class="SECT2"><a name="AEN56">2.3 System-specific
information</a></h2>
<p>Below is an overview of the UltraSPARC hardware that
FreeBSD runs on. The GENERIC kernel configuration file in

Overview</a></h2>
<p>A word of caution: the installed base for
FreeBSD/sparc64 is not nearly as large as for
FreeBSD/Intel. This means that the enormous variation of
PCI/ISA expansion cards out there has much less chance of
having been tested on sparc64 than on Intel. This is not
to imply they are doomed to fail, just that the chance of
running into something never tested before is much
higher. <tt class="FILENAME">GENERIC</tt> contains things
that are known to work on sparc64 only.</p>
<p>The PCI bus is fully supported. SBus support is
limited, but is reported to work well enough to netboot
an SBus-based Ultra 2 workstation.</p>
<p>1.44 Mbyte floppy drives are <span class="emphasis"><i
class="EMPHASIS">not</i></span> yet supported.</p>
<p>ATA and ATAPI (IDE) devices are supported via the <a

framework. <span class="emphasis"><i class=
"EMPHASIS">(not yet committed - in Perforce
tree)</i></span></p>
<p>There is full SCSI support via the CAM layer. However,
only NCR/Symbios cards are currently working. Adaptec
2940x (AIC 7xxx chip-based) and <a href=

<span class="CITEREFENTRY"><span class=
"REFENTRYTITLE">isp</span>(4)</span></a> cards should be
supported soon. Be aware that SCSI cards must contain Sun
FCODE in order to use them as a boot device from
OpenBoot.</p>
<p>If you want to boot your sparc64 over the Ethernet you
will obviously need an Ethernet card that the OpenBoot
console recognizes.</p>
<p><tt class="DEVICENAME">hme</tt>, <tt class=

<p>This section describes the devices currently known to be
supported by with FreeBSD on the UltraSPARC platform. Other
configurations may also work, but simply have not been
tested yet. Feedback, updates, and corrections to this list
are encouraged.</p>
<p>Where possible, the drivers applicable to each device or
class of devices is listed. If the driver in question has a
manual page in the FreeBSD base distribution (most should),
it is referenced here.</p>

Hardware</a></h2>
<p>In general, any device for which there is a driver can
be made to work on sparc64. Some drivers might just work,
others might require some changes (because this is the
first big-endian architecture to be supported by
FreeBSD).</p>
<p>The following drivers are known to work:</p>

<p>The paragraph about PCI drivers apply to ISA drivers
as well, but with the notable exception that ISA DMA is
not yet supported. This are generally on-board devices;
there are no UltraSPARC boxes with ISA slots that the
authors are aware of.</p>
<p>The following drivers are known to work:</p>

<h2 class="SECT2"><a name="AEN259">3.4 EBus
Hardware</a></h2>
<p>The EBus is specific to Sun hardware, so drivers need
to have support added to work with these devices. It is
quite similar to ISA, so that ISA drivers can usually be
easily ported, provided that they use the bus space
interface, and not in[bwl]/out[bwl] and related
functions. DMA is not yet supported.</p>
