<title>Kernel Compilation Settings</title>
<para>If you have an Intel P6 (Pentium Pro, Pentium II and later) it is recommended 
that you compile <acronym>MTRR</acronym> (Memory Type Range Registers) support into the kernel.
The kernel can map Cyrix and AMD <acronym>CPU</acronym>s to the
<acronym>MTRR</acronym> interface so selecting this
option is useful for those processors also.
This option is found in the 
"Processor type and features" menu.  It can increase performance of
image write operations 2.5 times or more on <acronym>PCI</acronym> or
<acronym>AGP</acronym> video cards.</para>

<para>In the "Character Devices" section, enable <acronym>AGP</acronym> Support and select the chipset
support on your motherboard.  If you do not know the chipset, you may select
all the chip types at the expense of extra kernel size. You can usually 
determine your motherboard's chipset by doing:</para>
<screen><userinput><command>cat /proc/pci</command></userinput></screen>

<para>In the "Character Devices" section, <emphasis>disable</emphasis> Direct 
Rendering Manager unless you have a Direct Rendering Infrastructure
(<acronym>DRI</acronym>) 
supported video card.  A complete list of <acronym>DRI</acronym> supported video cards can
be found at <ulink url="http://dri.sourceforge.net" /> in the Status section.  
Currently,
supported cards include those from 3dfx (Voodoo, Banshee), 3Dlabs, 
ATI (Rage Pro, Rage 128,
Radeon 7X00, Radeon 2), Intel (i810, i815), and Matrox (G200, G400, G450). 
If you do enable <acronym>DRI</acronym> here, make sure you select the video card(s) you want 
to support as a <emphasis>module</emphasis>.</para>

<para>Additionally NVidia provides their own closed source binary drivers,
which do not make use of <acronym>DRI</acronym>. If you intend to use these drivers,
do not enable <acronym>DRI</acronym>.</para>

<para>If you made any changes to the kernel configuration, recompile with</para>
<screen><userinput>make dep &amp;&amp;
make bzImage &amp;&amp;
make modules &amp;&amp;
make modules_install</userinput></screen>

<para>Copy <filename>/usr/src/linux/arch/i386/boot/bzImage</filename> and
<filename>/usr/src/linux/System.map</filename> to
<filename>/boot</filename>, edit <filename>/etc/lilo.conf</filename>
appropriately and run <filename>lilo</filename>. If you use 
<filename>grub</filename>, edit <filename>/boot/grub/grub.conf</filename> 
and add the new kernel to the boot menu.
</para>

<note><para>If you build <application>XFree86</application> in a chroot environment, make sure the kernel 
version of the base system and the target system are the same.  This is 
especially important if you enabled <acronym>DRI</acronym> support as a module as 
instructed above.</para></note>

<sect3><title>Creating <filename>host.def</filename></title>

<para>Although <application>XFree86</application> will compile without a
<filename>host.def</filename> file, the following file 
is recommended for customizing the installation. Start from 
the <filename class="directory">xc</filename> directory.</para>

<note><para>The <filename>host.def</filename> file is a
<application>C</application> file, not the 
usual configuration file.  If you make any changes, be sure the comment characters
(<userinput>/*</userinput> and <userinput>*/</userinput>) 
are balanced.  Most of the entries in the file below are
commented out with the default settings shown.

<title>Updating Direct Rendering Infrastructure (<acronym>DRI</acronym>)</title>
<para>If you have one of the supported <acronym>DRI</acronym> cards and
have enabled <acronym>DRI</acronym> kernel modules as explained
above, you now need to update the kernel modules to ensure they are compatible with the
current version of <application>XFree86</application>.  To do this, perform the following:</para>

<screen><userinput><command>cd programs/Xserver/hw/xfree86/os-support/linux/drm/kernel &amp;&amp; 
make  CC=/opt/gcc-2.95.3/bin/gcc -f Makefile.linux  &amp;&amp;

    /lib/modules/`uname -r`/kernel/drivers/char/drm/  &amp;&amp;

<warning><para>If you recompile or upgrade your kernel, you will need to re-copy the 
appropriate driver module(s)
to the kernel module library and rerun <command>depmod</command>.</para></warning>

<note><para>If you created <acronym>AGP</acronym> support as a module when compiling the kernel, you may
have to add a line to <filename>/etc/modules.conf</filename> to ensure
the agpgart module is loaded.  For instance, the <acronym>AGP</acronym> version of the Radeon video card
will use the <filename>radeon.o</filename> driver.  It will
need to have the line <screen>below radeon agpgart</screen> in 
<filename>/etc/modules.conf</filename> to enable <acronym>DRI</acronym> support.</para></note>
