This page provides an overview of Funtoo Linux sub-architectures (also called ''subarches'',) designed for quick and easy reference. While this information is available in other places, such as Wikipedia, it often takes some time to study and cross-reference the various articles to get a good understanding of each type of sub-architecture, and this information generally isn't all collected neatly in one place. That is the purpose of this page. When possible, links to more detailed Wikipedia pages are provided. You are encouraged to help maintain this page as well as the Wikipedia articles referenced here.
 
== 64-bit Suport (Generic) ==
 
=== generic_64 ===
 
The '''generic_64''' subarch is designed to support 64-bit PC-compatible CPUs, such as the [[Wikipedia:AMD_K8|AMD K8-series processors]], which were introduced in late 2003. They were notable as the first processors that supported the [[Wikipedia:X86-64|AMD64 (also called X86-64) 64-bit instruction set]] for PC-compatible systems, which was introduced as a backwards-compatible 64-bit alternative to Intel's IA-64 architecture. Intel followed suit and also began supporting this 64-bit instruction set, which they called "[[Wikipedia:X86-64#Intel_64|Intel 64]]", by releasing X86-64 64-bit compatible CPUs from mid-2004 onwards (See [[Wikipedia:X86-64#Intel_64_implementations|Intel 64 implementations]].)
 
AMD desktop 64-bit CPUs include the Athlon 64, Athlon 64 FX, Athlon 64 X2, Athlon X2, Turion 64, Turion 64 X2 and Sempron series processors. AMD server processors were released under the Opteron brand and have codenames SledgeHammer, Venus, Troy, Athens, Denmark, Italy, Egypt, Santa Ana and Santa Rosa. All Opterons released through late 2006 were based on the K8 microarchitecture with original X86-64 instructions.

The '''amd64-k10''' subarch provides support for the [[Wikipedia:AMD_10h|AMD Family 10h processors]], which were released in late 2007 as a successor to the AMD K8 series processors.
Você também precisará copiar no <code>resolv.conf</code> a fim de ter uma resolução de nome de DNS adequado de dentro do chroot:
 
Desktop amd64-k10 CPUs include [[Wikipedia:AMD Phenom|AMD Phenom]], [[Wikipedia:AMD_10h#Phenom_II_Models|AMD Phenom II]] and [[Wikipedia:AMD_10h#Athlon_II_Models|AMD Athlon II]]. Server CPUs include Opterons with codenames Budapest, Barcelona, Suzuka, Shanghai, Istanbul, Lisbon, and Magny-Cours. A full listing of amd64-k10 Opteron models [[Wikipedia:List_of_AMD_Opteron_microprocessors#K10_based_Opterons|can be found here]].
 
=== amd64-bulldozer ===
 
The '''amd64-bulldozer''' subarch supports the [[Wikipedia:Bulldozer (microarchitecture)|AMD bulldozer microarchitecture]] CPUs, which were released from late 2011 through the first quarter of 2012 as a replacement for the [[Wikipedia:AMD_10h|K10 microarchitecture]] CPUs.
Bulldozer desktop CPUs use the [[Wikipedia:Socket_AM3+|AM3+ socket]] and server CPUs use the  [[Wikipedia:Socket_G34|G34 socket]].
 
Desktop bulldozer CPUs include the [[Wikipedia:List_of_AMD_FX_microprocessors#.22Zambezi.22_.2832_nm_SOI.29|Zambezi FX-series CPUs]]. Server bulldozer CPUs include Opterons with codenames Zurich (Opteron 3200-series), Valencia (Opteron 4200-series) and Interlagos (Opteron 6200 series). A complete list of Opteron models [[Wikipedia:http://en.wikipedia.org/wiki/Opteron#Opteron_.2832_nm_SOI.29-_First_Generation_Bulldozer_Microarchitecture|can be found here.]].
 
=== amd64-piledriver ===
 
The '''amd64-piledriver''' subarch supports the [[Wikipedia:Piledriver (microarchitecture)|AMD Piledriver microarchitecture]] produced by AMD from mid-2012 through 2015, which is the successor to the [[Wikipedia:Bulldozer (microarchitecture)|AMD bulldozer microarchitecture]].
Piledriver CPUs and APUs are available that use the [[Wikipedia:FM2 Socket|FM2 socket]]. Desktop Piledriver CPUs use the [[Wikipedia:Socket_AM3+|AM3+ socket]]. Server Piledriver CPUs use a variety of sockets, including [[Wikipedia:Socket_AM3+|AM3+]], [[Wikipedia:Socket_C32|C32]] and [[Wikipedia:Socket_G34|G34]].
 
Desktop piledriver CPU and APUs include FX-series with codename Vishera (FX-8350, FX-8370),  [[Wikipedia:List_of_AMD_accelerated_processing_unit_microprocessors#Virgo:_.22Trinity.22_.282012.2C_32_nm.29|A-series with codename Trinity]] (A6-5400K, A10-5800K) and [[Wikipedia:http://en.wikipedia.org/wiki/List_of_AMD_accelerated_processing_unit_microprocessors#.22Richland.22_.282013.2C_32_nm.29_2|A-series with codename Richland]].
 
Server piledriver CPUs include Opterons with codenames Delhi (Opteron 3300-series, [[Wikipedia:Socket_AM3+|AM3+]]), Seoul (Opteron 4300-series, [[Wikipedia:Socket_C32|C32]])  and Abu Dhabi (Opteron 6300-series, [[Wikipedia:Socket_G34|G34]]). A full listing of Opteron models [[Wikipedia:Opteron#Opteron_.2832_nm_SOI.29_-_Piledriver_Microarchitecture|is available here]].
 
Piledriver adds several new instructions over bulldozer, so AMD bulldozer systems cannot run amd64-piledriver-optimized stages. However, this subarch is  instruction-compatible with its successor, the, so amd64-piledriver stages can run on amd64-steamroller systems, and vice versa.
 
=== amd64-steamroller ===
 
The '''amd64-steamroller''' subarch supports the  [[Wikipedia:Steamroller (microarchitecture)|AMD steamroller microarchitecture]], produced from early 2014. It is the successor to the [[Wikipedia:Piledriver (microarchitecture)|AMD Piledriver microarchitecture]].
Steamroller APUs are available that use the [[Wikipedia:FM2+ Socket|FM2+ socket]] and  [[Wikipedia:Socket_FP3|FP3 socket]] (mobile.)
 
Desktop steamroller APUs include the [[Wikipedia:AMD_Accelerated_Processing_Unit#Steamroller_architecture_.282014.29:_Kaveri|A-Series with codename Kaveri]], such as the quad-core AMD A10-7850K APU. Steamroller APUs are also available in mobile versions. Server steamroller APUs will include the codename Berlin APUs, which are expected to be released some time in 2015.
 
Amd64-steamroller subarches are instruction-compatible with amd64-piledriver, but add new instructions over amd64-bulldozer.
 
=== amd64-jaguar ===
 
The '''amd64-jaguar''' (also called AMD Family 16h) subarch supports the  [[Wikipedia:Jaguar (microarchitecture)|AMD jaguar microarchitecture]], which is targeted at low-power devices, including notebooks, tablets and small form-factor desktops and servers. It is perhaps most well-known for being the microarchitecture used for the [[Wikipedia:Playstation 4|Playstation 4]] and [[Wikipedia:Xbox One|Xbox One]], which each use custom 8-core Jaguar APUs.
Socketed Jaguar APUs use the [[Wikipedia:AM1 Socket|AM1 socket]], and  [[Wikipedia:Socket_FT3|FT3 socket]] for mobile devices. G-series [[Wikipedia:System_on_a_chip|"system on a chip" (SoC)]] APUs are available for non-socketed devices such as tablets and embedded system boards.
 
Desktop Jaguar APUs include the [[Wikipedia:List_of_AMD_accelerated_processing_unit_microprocessors#.22Kabini.22.2C_.22Temash.22_.282013.2C_28_nm.29|Kabini A-series APUs and Temash E-series APUs]], such as the Athlon 5150 and 5350 APUs, and Sempron 2650 and 3850.
 
Amd64-jaguar subarches use the MOVBE instruction which is not available on amd64-bulldozer, amd64-piledriver or amd64-steamroller. They are thus not instruction-compatible with any of these subarches.

The Intel Atom Processor is the common name for Intel's  [[Wikipedia:Bonnell_(microarchitecture)|Bonnell microarchitecture]],  which represents a partial revival of the principles used in earlier Intel designs such as P5 and the i486, with the sole purpose of enhancing the performance per watt ratio.  Successor to the [[Wikipedia:Stealey_(microprocessor)|Intel A100 series (Stealey)]], which was derived from the [[Wikipedia:Pentium_M|Pentium M]], the Intel Atom has been produced since 2008. Targeted at low-power devices, Atom processors can be found in a wide range of notebooks, tablets and small form-factor desktops and servers.  
 
The '''atom_64''' sub-architecture supports 64-bit capable Intel Atom CPUs.  The first 64-bit capable Intel Atom CPUs were the Intel Atom 230 and 330, released in late 2008. However, Intel also continued to produce new 32-bit Atom Processors after this date. For example, the Atom N2xx series Atom Diamondville models cannot support 64-bit operation, while the 2xx and 3xx Diamondville, Pineview, Cedarview and Centerton can. A full list of 64-bit capable Intel Atom Processors [http://ark.intel.com/search/advanced?s=t&FamilyText=Intel%C2%AE%20Atom%E2%84%A2%20Processor&InstructionSet=64-bit can be seen here.]
 
{{Important|For 64-bit support to be functional, a 64-bit capable Atom Processor must be paired ''with a processor, chipset, and BIOS'' that all support [[Wikipedia:X86-64#Intel_64|Intel 64]]. If not all hardware supports 64-bit, then you must use the [[subarches#atom_32|atom_32]] subarch instead.}}

Chroot no Funtoo

Antes de iniciar o chroot no seu novo sistema, há algumas coisas que precisam ser feitas antes. Vcê precisará montar /proc e /dev dentro do seu novo sistema. Utilize os seguintes comandos: 

root # cd /mnt/funtoo
root # mount -t proc none proc
root # mount --rbind /sys sys
root # mount --rbind /dev dev


   Note

Esse é um template que é utilizado como parte das instruções de instalação, para descrever o processo de inicialização do chroot no stage3. Templates estão sendo utilizados para permitir múltiplos guias de instalação variantes que utilizam a maioria das mesmas pates reutilizáveis.


Você também precisará copiar no resolv.conf a fim de ter uma resolução de nome de DNS adequado de dentro do chroot: 

root # cp /etc/resolv.conf etc

Agora você pode iniciar o chroot no seu novo sistema. Utilize env antes de iniciar o chroot para asegura-se de que nenhuma variáveis de ambiente da mídia de instalação sejam utilizadas pelo seu sistema: 

root # env -i HOME=/root TERM=$TERM chroot . bash -l
   Note

Users of live CDs with 64-bit kernels installing 32-bit systems: Some software may use uname -r to check whether the system is 32 or 64-bit. You may want append linux32 to the chroot command as a workaround, but it's generally not needed.

   Important

If you receive the error "chroot: failed to run command `/bin/bash': Exec format error", it is probably because you are running a 32-bit kernel and trying to execute 64-bit code. SystemRescueCd boots with a 32-bit kernel by default.

It's also a good idea to change the default command prompt while inside the chroot. This will avoid confusion if you have to change terminals. Use this command: 

root # export PS1="(chroot) $PS1"

Congratulations! You are now chrooted inside a Funtoo Linux system. Now it's time to get Funtoo Linux properly configured so that Funtoo Linux will boot successfully when your system is restarted.
