If a version is listed under {{c|Latest version installed}}, then debian-sources is already pre-built for you and you can skip the rest of the Kernel section, and proceed to the [[#Installing a Bootloader|Installing a Bootloader section]].
=== Firmware ===


{{Important|1=
At this point it is wise to emerge latest {{c|sys-kernel/linux-firmware}} package, because various drivers rely on firmware blobs and instructions. Hardware like wi-fi cards, graphic cards, network cards, and others will not work properly or at all if firmware not present.}}


==== Building the Kernel ====
Neste ponto, é aconselhável emergir o pacote mais recente de {{c | sys-kernel/linux-firmware}}, porque vários drivers contam com instruções e BLOBs (Binary Large Object) contendo firmware. Hardware como placas Wi-Fi, placas gráficas, placas de rede e outras não funcionarão corretamente caso o firmware não esteja disponível.

If you need to build a kernel for Funtoo Linux, please follow these steps:
 
{{Note|1=
See [[Funtoo Linux Kernels]] for a full list of kernels supported in Funtoo Linux. We recommend <code>debian-sources</code> for new users.}}
 
{{Important|1=
<code>debian-sources</code> with <code>binary</code> USE flag requires at least 20GB free in <code>/var/tmp</code> and takes around 1 hour to build on a Intel Core i7 Processor.}}
 
Let's emerge our kernel:


{{console|body=
{{console|body=
(chroot) # ##i##emerge debian-sources
%chroot% ##i##emerge -av linux-firmware
}}
}}


Once <code>emerge</code> completes, you'll have a brand new kernel and initramfs installed to <code>/boot</code>, plus kernel headers installed in <code>/usr/src/linux</code>, and you'll be ready to configure the boot loader to load these to boot your Funtoo Linux system.
<noinclude>{{InstallNavigation|num=13|prev=Introducing Portage|next=Bootloader|align=right}}</noinclude>
 
{{warning|If you have a RAID in your machine, the kernel installation will pull in the <code>mdadm</code> tool as a dependency. It is important to edit the <code>/etc/mdadm.conf</code> file prior to rebooting the machine so the RAID is properly recognised and set up before the kernel attempts to mount it in the tree. Failing to do so can result in an unusable or even unbootable system! For specific details, consult the mdadm man page <code>man mdadm</code> or the [[Package:Mdadm|mdadm]] ebuild page.}}
 
{{fancynote|NVIDIA card users: the <code>binary</code> USE flag installs the Nouveau drivers which cannot be loaded at the same time as the proprietary drivers, and cannot be unloaded at runtime because of KMS. You need to blacklist it under <code>/etc/modprobe.d/</code>.}}
 
{{fancynote|For an overview of other kernel options for Funtoo Linux, see [[Funtoo Linux Kernels]]. There may be modules that the Debian kernel doesn't include, a situation where [http://www.funtoo.org/wiki/Funtoo_Linux_Kernels#Using_Debian-Sources_with_Genkernel genkernel] would be useful. Also be sure to see [[:Category:Hardware Compatibility|hardware compatibility]] information.}}

Firmware

Neste ponto, é aconselhável emergir o pacote mais recente de sys-kernel/linux-firmware, porque vários drivers contam com instruções e BLOBs (Binary Large Object) contendo firmware. Hardware como placas Wi-Fi, placas gráficas, placas de rede e outras não funcionarão corretamente caso o firmware não esteja disponível. Se estiver usando a imagem stage3 , execute o seguinte para instalá-la. O linux-firmware já estará instalado se estiver usando a imagem gnome : 

chroot # emerge -av linux-firmware
