<para>Since mid-2003 &os;/&arch; has supported the &arch.print;
|
|
(<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; should support the both.</para>
|

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

supported:</para>

<para>Intel 64-bit Xeon (<quote>Nacona</quote>).
|
|
This processor is fabricated on 90nm process technology, and operates
|
|
with 2.80 to 3.60 GHz (FSB 800MHz) and Intel E7520/E7525/E7320 chipsets.</para>

<para>Intel Pentium 4 Processor supporting Intel EM64T
|
|
(<quote>Prescott</quote>).
|
|
This is fabricated on 90nm process technology,
|
|
uses FC-LGA775 package, and operates with 3.20F/3.40F/3.60F GHz
|
|
and Intel 925X Express chipsets.
|
|
The corresponding S-Spec numbers are SL7L9, SL7L8, SL7LA, SL7NZ, SL7PZ,
|
|
and SL7PX. Note that processors marked as 5xx numbers do not support
|
|
EM64T.</para>

<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 8GB. SMP support has been
|
|
recently completed and is reasonably robust.</para>
|
|
|
|
<para>In many respects, &os;/&arch; is similar to &os;/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; 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>
