    <title>Introduction</title>

    <para>This document contains the hardware compatibility notes for
      &os; &release.current;.  It lists the hardware platforms
      supported by &os;, as well as the various types of hardware
      devices (storage controllers, network interfaces, and so on),
      along with known working instances of these devices.</para>

  <sect1 id="proc">
    <title>Supported Processors and System Boards</title>

    <para>This section provides some architecture-specific information
      about the specific processors and systems that are supported by
      each architecture.</para>

    <sect2 id="proc-amd64">
      <title>amd64</title>

      <para>Since mid-2003 &os;/&arch.amd64; has supported the AMD64
	(<quote>Hammer</quote>) and &intel; EM64T architecture, and is
	now one of the Tier-1 platforms (fully supported
	architecture), which are expected to be Production Quality
	with respects to all aspects of the &os; operating system,
	including installation and development environments.</para>

      <para>Note that there are two names for this architecture, AMD64
	(AMD) and Intel EM64T (Extended Memory 64-bit Technology).
	64-bit mode of the two architectures are almost compatible
	with each other, and &os;/&arch.amd64; should support them
	both.</para>

      <para>As of this writing, the following processors are
	supported:</para>

      <itemizedlist>
	<listitem>
	  <para>&amd.athlon;64 (<quote>Clawhammer</quote>).</para>

	</listitem>

	<listitem>
	  <para>All multi-core &intel; &xeon; processors except

            processors <quote>Nocona</quote>, <quote>Irwindale</quote>,

	    EM64T support.</para>
	</listitem>

	<listitem>
	  <para>All &intel; Core 2 (not Core Duo) and later

	</listitem>

	<listitem>
	  <para>All &intel; &pentium; D processors</para>
	</listitem>

	<listitem>
	  <para>&intel; &pentium; 4s and Celeron Ds using
	    the <quote>Cedar Mill</quote> core have EM64T
	    support.</para>
	</listitem>

	<listitem>
	  <para>Some &intel; &pentium; 4s and Celeron Ds using
	    the <quote>Prescott</quote> core have EM64T support.  See
	    the <ulink url="http://processorfinder.intel.com">Intel
	    Processor Spec Finder</ulink> for the definitive answer about
	    EM64T support in Intel processors.</para>
	</listitem>

      </itemizedlist>

      <para>&intel; EM64T is an extended version of IA-32 (x86) and
	different from &intel; IA-64 (Itanium) architecture, which
	&os;/ia64 supports.  Some &intel;'s old documentation refers
	to &intel; EM64T as <quote>64-bit extension technology</quote>
	or <quote>IA-32e</quote>.</para>

      <para>The largest tested memory configuration to date is 64GB.
	SMP support has been recently completed and is reasonably
	robust.</para>

      <para>In many respects, &os;/&arch.amd64; is similar to
	&os;/&arch.i386;, in terms of drivers supported.  There may be
	some issues with 64-bit cleanliness in some (particularly
	older) drivers.  Generally, drivers that already function
	correctly on other 64-bit platforms should work.</para>

      <para>&os;/&arch.amd64; is a very young platform on &os;.  While
	the core &os; kernel and base system components are generally
	fairly robust, there are likely to still be rough edges,
	particularly with third party packages.</para>

    </sect2>

    <sect2 id="proc-i386">
      <title>i386</title>

      <para>&os;/&arch.i386; runs on a wide variety of <quote>IBM PC
	  compatible</quote> machines. Due to the wide range of
	hardware available for this architecture, it is impossible
	to exhaustively list all combinations of equipment supported
	by &os;.  Nevertheless, some general guidelines are
	presented here.</para>

      <para>Almost all &i386;-compatible processors with a floating
	point unit are supported. All &intel; processors beginning
	with the 80486 are supported, including the 80486, &pentium;,
	&pentium; Pro, &pentium; II, &pentium; III, &pentium; 4, and
	variants thereof, such as the &xeon; and &celeron; processors.
	All &i386;-compatible AMD processors are also supported,
	including the &am486;, &am5x86;, K5, &amd.k6; (and variants),
	&amd.athlon; (including Athlon-MP, Athlon-XP, Athlon-4, and
	Athlon Thunderbird), and &amd.duron; processors.  The AMD
	&Eacute;lan SC520 embedded processor is supported.  The
	Transmeta Crusoe is recognized and supported, as are
	&i386;-compatible processors from Cyrix and NexGen.</para>

      <para>There is a wide variety of motherboards available for this
	architecture.  Motherboards using the ISA, VLB, EISA, AGP, and
	PCI expansion busses are well-supported.  There is some
	limited support for the MCA (<quote>MicroChannel</quote>)
	expansion bus used in the IBM PS/2 line of PCs.</para>

      <para>Symmetric multi-processor (SMP) systems are generally
	supported by &os;, although in some cases, BIOS or motherboard
	bugs may generate some problems.  Perusal of the archives of
	the &a.smp; may yield some clues.</para>

      <para>&os; will take advantage of HyperThreading (HTT) support
	on &intel; CPUs that support this feature.  A kernel with the
	<literal>options&nbsp;SMP</literal> feature enabled will
	automatically detect the additional logical processors.  The
	default &os; scheduler treats the logical processors the same
	as additional physical processors; in other words, no attempt
	is made to optimize scheduling decisions given the shared
	resources between logical processors within the same CPU.
	Because this naive scheduling can result in suboptimal
	performance, under certain circumstances it may be useful to
	disable the logical processors with the the
	<varname>machdep.hlt_logical_cpus</varname> sysctl variable.
	It is also possible to halt any CPU in the idle loop with the
	<varname>machdep.hlt_cpus</varname> sysctl variable.  The
	&man.smp.4; manual page has more details.</para>

      <para>&os; will take advantage of Physical Address Extensions
	(PAE) support on CPUs that support this feature.  A kernel
	with the <literal>PAE</literal> feature enabled will detect
	memory above 4 gigabytes and allow it to be used by the
	system.  This feature places constraints on the device drivers
	and other features of &os; which may be used; consult the
	&man.pae.4; manpage for more details.</para>

      <para>&os; will generally run on i386-based laptops, albeit with
	varying levels of support for certain hardware features such
	as sound, graphics, power management, and PCCARD expansion
	slots.  These features tend to vary in idiosyncratic ways
	between machines, and frequently require special-case support
	in &os; to work around hardware bugs or other oddities.  When
	in doubt, a search of the archives of the &a.mobile; may be
	useful.</para>

      <para>Most modern laptops (as well as many desktops) use the
	Advanced Configuration and Power Management (ACPI) standard.
	&os; supports ACPI via the ACPI Component Architecture
	reference implementation from &intel;, as described in the
	&man.acpi.4; manual page.  The use of ACPI causes
	instabilities on some machines and it may be necessary to
	disable the ACPI driver, which is normally loaded via a kernel
	module.  This may be accomplished by adding the following line
	to <filename>/boot/device.hints</filename>:</para>

      <programlisting>hint.acpi.0.disabled="1"</programlisting>

      <para>Users debugging ACPI-related problems may find it useful
	to disable portions of the ACPI functionality.  The
	&man.acpi.4; manual page has more information on how to do
	this via loader tunables.</para>

      <para>ACPI depends on a Differentiated System Descriptor Table
	(DSDT) provided by each machine's BIOS.  Some machines have
	bad or incomplete DSDTs, which prevents ACPI from functioning
	correctly.  Replacement DSDTs for some machines can be found
	at the <ulink
	  url="http://acpi.sourceforge.net/dsdt/index.php">DSDT</ulink>
	section of the <ulink
	  url="http://acpi.sourceforge.net/">ACPI4Linux</ulink> project
	Web site.  &os; can use these DSDTs to override the DSDT
	provided by the BIOS; see the &man.acpi.4; manual page for
	more information.</para>
    </sect2>

    <sect2 id="proc-ia64">
      <title>ia64</title>

      <para>Currently supported processors are the <ulink
	  url="http://people.freebsd.org/~marcel/refs/ia64/itanium/24532003.pdf">&itanium;</ulink>
	and the <ulink
	  url="http://people.freebsd.org/~marcel/refs/ia64/itanium2/25111003.pdf">&itanium;

      <para>Supported chipsets include:</para>

	</listitem>
      </itemizedlist>

      <para>Both Uniprocessor (UP) and Symmetric Multi-processor (SMP)
	configurations are supported.</para>

      <para>Most devices that can be found in or are compatible with
	&arch.ia64; machines are fully supported.  The notable
	exception is the VGA console. The &os; support for VGA
	consoles is at this time too much based on PC hardware and not
	all &arch.ia64; machines have chipsets that provide sufficient
	PC legacy support. As such &man.syscons.4; can not be enabled
	and the use of a serial console is required.</para>
    </sect2>

    <sect2 id="proc-pc98">
      <title>pc98</title>

      <para>NEC PC-9801/9821 series with almost all &i386;-compatible
	processors, including 80486, &pentium;, &pentium; Pro,
	&pentium; II, and variants.  All &i386;-compatible processors
	by AMD, Cyrix, IBM, and IDT are also supported.</para>

      <para>NEC FC-9801/9821 series, and NEC SV-98 series (both of
	them are compatible with PC-9801/9821 series) should be
	supported.</para>

      <para>EPSON PC-386/486/586 series, which are compatible with NEC
	PC-9801 series are supported.</para>

      <para>High-resolution mode is not supported.  NEC
	PC-98XA/XL/RL/XL^2, and NEC PC-H98 series are supported in
	normal (PC-9801 compatible) mode only.</para>

      <para>Although there are some multi-processor systems (such as
	Rs20/B20), SMP-related features of &os; are not supported
	yet.</para>

      <para>PC-9801/9821 standard bus (called C-Bus), PC-9801NOTE
	expansion bus (110pin), and PCI bus are supported.  New Extend
	Standard Architecture (NESA) bus (used in PC-H98, SV-H98, and
	FC-H98 series) is not supported.</para>

  <!--

  The "Supported Devices" section of the release notes.
  Generally processor-independent, with conditional text
  inclusion handling any architecture-dependent text.

  Within each subsection describing a class of hardware
  (i.e. Ethernet interfaces), list broad groups of devices
  alphabetically as paragraphs sorted alphabetically (frequently
  these groups will be arranged by manufacturer, i.e. 3Com
  Ethernet interfaces).

  Where applicable, a "Miscellaneous" section may follow all
  other named sections.

  These guidelines are not hard-and-fast rules, and exceptions
  will occur.  Following these guidelines (vague as they may be)
  is highly recommended to try to keep the formatting of
  this section consistent.

  We give manpage references using the &man entities where
  possible.  If a driver has no manpage (and consequently no
  &man entity, we simply give the name of the driver).
  Please avoid doing &man entity conversions unless you
  know for sure that an entity and manpage exist; sweeps through
  this file to fix "missed" conversions are likely to break the
  build.
  -->

  <sect1 id="support">
    <title>Supported Devices</title>

    <para>This section describes the devices currently known to be
      supported by &os;.  Other configurations may also work, but
      simply have not been tested yet.  Feedback, updates, and
      corrections to this list are encouraged.</para>

    <para>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 &os; base distribution (most should), it is
      referenced here.  Information on specific models of supported
      devices, controllers, etc. can be found in the manual
      pages.</para>

    <note>
      <para>The device lists in this document are being generated
	automatically from &os; manual pages.  This means that some
	devices, which are supported by multiple drivers, may appear
	multiple times.</para>
