=== Installing a Bootloader ===
+
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.
  
These install instructions show you how to use GRUB to boot using BIOS (old-school) or UEFI (new-school).
+
== 64-bit Suport (Generic) ==
 
+
==== Old School (BIOS) ====
+
 
+
If you're using the BIOS to boot, setting up GRUB, the bootloader, is pretty easy.
+
 
+
To use this recommended boot method, first emerge <code>boot-update</code>. This will also cause <code>grub-2</code> to be merged, since it is a dependency of <code>boot-update</code>.
+
  
 +
=== generic_64 ===
 
<console>
 
<console>
(chroot) # ##i##emerge boot-update
+
CFLAGS: -mtune=generic -O2 -pipe
 +
CHOST: x86_64-pc-linux-gnu
 +
USE: mmx sse sse2
 
</console>
 
</console>
  
Then, edit <code>/etc/boot.conf</code> and specify "<code>Funtoo Linux genkernel</code>" as the <code>default</code> setting at the top of the file, replacing <code>"Funtoo Linux"</code>.  
+
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]].)
  
<code>/etc/boot.conf</code> should now look like this:
+
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.
  
<pre>
+
== 64-bit AMD Processors ==
boot {
+
        generate grub
+
        default "Funtoo Linux genkernel"
+
        timeout 3
+
}
+
  
"Funtoo Linux" {
+
=== amd64-k10 ===
        kernel bzImage[-v]
+
<console>
        # params += nomodeset
+
CFLAGS: -march=amdfam10 -O2 -pipe
}
+
CHOST: x86_64-pc-linux-gnu
</pre>
+
USE: mmx sse sse2 sse3 3dnow 3dnowext
 +
</console>
  
Please read <code>man boot.conf</code> for further details.
+
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.
  
===== Running grub-install and boot-update =====
+
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]].
 
+
Finally, we will need to actually install the GRUB boot loader to your disk, and also run <code>boot-update</code> which will generate your boot loader configuration file:
+
  
 +
=== amd64-bulldozer ===
 
<console>
 
<console>
(chroot) # ##i##grub-install --no-floppy /dev/sda
+
CFLAGS: -march=bdver1 -O2 -pipe
(chroot) # ##i##boot-update
+
CHOST: x86_64-pc-linux-gnu
 +
USE: mmx sse sse2 sse3 sse4 3dnow 3dnowext
 
</console>
 
</console>
  
Now you need to update your boot loader configuration file:
+
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 ===
 
<console>
 
<console>
(chroot) # ##i##boot-update
+
CFLAGS: -march=bdver2 -O2 -pipe
 +
CHOST: x86_64-pc-linux-gnu
 +
USE: mmx sse sse2 sse3 sse4 3dnow 3dnowext
 
</console>
 
</console>
You only need to run <code>grub-install</code> when you first install Funtoo Linux, but you need to re-run <code>boot-update</code> every time you modify your <code>/etc/boot.conf</code> file, so your changes are applied on next boot.
 
  
==== New School (UEFI) ====
+
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]].
  
If you're using UEFI to boot, setting up the boot loader is a bit more complicated for now, but this process will be improving soon. Perform the following steps.
+
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]].  
  
===== Unmask Grub 2.02_beta2 =====
+
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]].
  
Unmask the latest version of GRUB by placing this in your <code>/etc/portage/package.unmask</code>:
+
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.
  
<pre>
+
=== amd64-steamroller ===
sys-boot/grub
+
<console>
</pre>
+
CFLAGS: -march=bdver3 -O2 -pipe
 +
CHOST: x86_64-pc-linux-gnu
 +
USE: mmx sse sse2 sse3 sse4 3dnow 3dnowext
 +
</console>
  
The 2.00 version of GRUB has known issues with UEFI booting. Using 2.02 is essential for having this boot method work reliably.
+
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.)
  
===== Emerging GRUB =====
+
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 Berlin APUs, which are expected to be released some time in 2015.
  
You will still use GRUB as a boot loader, but before emerging grub, you will need to enable EFI booting. To do this,
+
Amd64-steamroller subarches are instruction-compatible with amd64-piledriver, but add new instructions over amd64-bulldozer.
add the following line to <code>/etc/make.conf</code>:
+
  
<pre>
+
=== amd64-jaguar ===
GRUB_PLATFORMS="efi-64"
+
<console>
</pre>
+
CFLAGS: -march=btver2 -O2 -pipe
 +
CHOST: x86_64-pc-linux-gnu
 +
USE: mmx sse sse2 sse3 sse4 3dnow 3dnowext
 +
</console>
  
Then, <code>emerge boot-update</code>. You will notice <code>grub</code> and <code>efibootmgr</code> getting pulled in as dependencies. This is expected and good.
+
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.
  
===== Installing GRUB =====
+
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.
  
Now, for the magic of getting everything in place for booting. You should copy your kernel and initramfs (if you have one -- you will if you are following the default install) to <tt>/boot</tt>. GRUB will boot those. But how do we get UEFI to boot GRUB? Well, we need to run the following command:
+
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.
  
 +
== 64-bit Intel Processors ==
 +
=== core2_64 ===
 
<console>
 
<console>
# ##i##grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id="Funtoo Linux [GRUB]" --recheck /dev/sda
+
CFLAGS: -march=core2 -O2 -pipe
 +
CHOST: x86_64-pc-linux-gnu
 +
USE: mmx sse sse2 sse3 ssse3
 
</console>
 
</console>
This command will simply install all the stuff to <tt>/boot/EFI</tt> and <tt>/boot/grub</tt> that your system needs to boot. In particular, the <tt>/boot/EFI/grub/grubx64.efi</tt> file will be created. This is the GRUB boot image that UEFI will load and start.
 
  
A more detailed explanation of the flags used in the above command:
+
The '''core2_64''' subarch supports 64-bit-capable [[Wikipedia:Intel_Core_2|Intel Core 2 Processors]], which includes ''some'' processors of the [[Wikipedia:Intel Core (microarchitecture)|Core]] and all processors of the [[Wikipedia:Penryn_(microarchitecture)|Penryn]] microarchitecture. All "Core 2" branded processors are 64-bit-capable. These processors were introduced in July of 2006 and were phased out in July of 2011, in favor of  [[Wikipedia:Nehalem_(microarchitecture)|Nehalem-based]] processors.
* <code>--target=x86_64-efi</code>: Tells GRUB that we want to install it in a way that allows it to boot in UEFI
+
* <code>--efi-directory=/boot</code>: All GRUB UEFI files will be installed in ''/boot''
+
* <code>--bootloader-id="Funtoo Linux [GRUB]"</code>: This flag is not necessary for GRUB to boot. However, it allows you to change the text of the boot option in the UEFI BIOS. The stuff in the quotes can be set to anything that you would like.
+
* <code>--recheck</code>: If a device map already exists on the disk or partition that GRUB is being installed on, it will be removed.
+
* <code>/dev/sda</code>:The device that we are installing GRUB on.
+
  
===== Configuring GRUB =====
+
For a full list of 64-bit capable Core 2 processors, [http://ark.intel.com/search/advanced?s=t&FamilyText=Legacy%20Intel%C2%AE%20Core%E2%84%A22%20Processor&InstructionSet=64-bit see this link].
  
OK, now UEFI has the GRUB image it needs to boot. But we still need to configure GRUB itself so it finds and boots your kernel and initramfs. This is done by performing the following steps. Since boot-update doesn't yet support UEFI, we will use boot-update, but then edit our <code>/boot/grub/grub.cfg</code> to support UEFI booting.  
+
The 64-bit capable ''Core 2''-branded CPUs include: "Conroe"/"Allendale" (dual-core for desktops), "Merom" (dual-core for laptops), "Merom-L" (single-core for laptops), "Kentsfield" (quad-core for desktops), and the updated variants named "Wolfdale" (dual-core for desktops), "Penryn" (dual-core for laptops), and "Yorkfield" (quad-core for desktops). (Note: ''For the server and workstation "Woodcrest", "Tigerton", "Harpertown" and "Dunnington" CPUs see the [[Wikipedia:Xeon|Xeon]] brand''.)
  
First, you will need to edit <code>/etc/boot.conf</code>. Format this as you would if you were booting without UEFI. If you are not sure how this should look, below is an example of what it could look like if you are booting from an unencrypted ext4 partition:
+
=== corei7 ===
 +
<console>
 +
CFLAGS: -march=corei7 -O2 -pipe
 +
CHOST: x86_64-pc-linux-gnu
 +
USE: mmx sse sse2 sse3 ssse3 sse4
 +
</console>
  
{{file|name=/etc/boot.conf|desc=|body=
+
Beginning in November 2008, Intel launched the first Core i7 processor, codenamed [[Wikipedia:Bloomfield_(microprocessor)|Bloomfield]], based on the [[Wikipedia:Nehalem_(microarchitecture)|Nehalem]] microarchitecture. With this launch, they also added to and modified the conventions of the [[Wikipedia:Intel_Core|Intel Core]] branding scheme. '''(Not to be confused with the [[Wikipedia:Intel Core (microarchitecture)|Intel Core microarchitecture]], which has only been supported by the processors sold under the Core2 brand. See [[Subarches#core2_64|core2_64]].)'''. This new naming scheme distinguishes between grades of processors rather than microarchitectures or design. Therefore, the '''corei7''' subarch supports the [[Wikipedia:Nehalem_(microarchitecture)|Nehalem]], [[Wikipedia:Westmere_(microarchitecture)|Westmere]], [[Wikipedia:Sandy_Bridge_(microarchitecture)|Sandy Bridge]],  [[Wikipedia:Ivy_Bridge_(microarchitecture)|Ivy Bridge]], and [[Wikipedia:Haswell_(microarchitecture)|Haswell]] microarchitectures under the follow brand names:
boot {
+
        generate grub
+
        default "Funtoo Linux"
+
        timeout 3
+
}
+
  
"Funtoo Linux" {
+
* Intel Core i3 (entry-level consumer)
        kernel vmlinuz[-v]
+
* Intel Core i5 (mainstream consumer)
        params += rootfstype=ext4 root=/dev/sda2
+
* Intel Corei7 (high-end consumer/business)
}
+
* Intel Xeon (business server/workstation)
}}
+
  
After you have edited your <code>/etc/boot.conf</code> file, run <code>boot-update</code>. If you check your <code>/boot/grub/grub.cfg</code> now, you should see something like this:
+
=== atom_64 ===
 
+
<console>
{{file|name=/boot/grub/grub.cfg|desc=|body=

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.]

Funtoo Linux Sub-Architectures

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

CFLAGS: -mtune=generic -O2 -pipe
CHOST: x86_64-pc-linux-gnu
USE: mmx sse sse2

The generic_64 subarch is designed to support 64-bit PC-compatible CPUs, such as the AMD K8-series processors, which were introduced in late 2003. They were notable as the first processors that supported the 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 "Intel 64", by releasing X86-64 64-bit compatible CPUs from mid-2004 onwards (See 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.

64-bit AMD Processors

amd64-k10

CFLAGS: -march=amdfam10 -O2 -pipe
CHOST: x86_64-pc-linux-gnu
USE: mmx sse sse2 sse3 3dnow 3dnowext

The amd64-k10 subarch provides support for the AMD Family 10h processors, which were released in late 2007 as a successor to the AMD K8 series processors.

Desktop amd64-k10 CPUs include AMD Phenom, AMD Phenom II and 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 can be found here.

amd64-bulldozer

CFLAGS: -march=bdver1 -O2 -pipe
CHOST: x86_64-pc-linux-gnu
USE: mmx sse sse2 sse3 sse4 3dnow 3dnowext

The amd64-bulldozer subarch supports the AMD bulldozer microarchitecture CPUs, which were released from late 2011 through the first quarter of 2012 as a replacement for the K10 microarchitecture CPUs. Bulldozer desktop CPUs use the AM3+ socket and server CPUs use the G34 socket.

Desktop bulldozer CPUs include the 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 can be found here..

amd64-piledriver

CFLAGS: -march=bdver2 -O2 -pipe
CHOST: x86_64-pc-linux-gnu
USE: mmx sse sse2 sse3 sse4 3dnow 3dnowext

The amd64-piledriver subarch supports the AMD Piledriver microarchitecture produced by AMD from mid-2012 through 2015, which is the successor to the AMD bulldozer microarchitecture. Piledriver CPUs and APUs are available that use the FM2 socket. Desktop Piledriver CPUs use the AM3+ socket. Server Piledriver CPUs use a variety of sockets, including AM3+, C32 and G34.

Desktop piledriver CPU and APUs include FX-series with codename Vishera (FX-8350, FX-8370), A-series with codename Trinity (A6-5400K, A10-5800K) and A-series with codename Richland.

Server piledriver CPUs include Opterons with codenames Delhi (Opteron 3300-series, AM3+), Seoul (Opteron 4300-series, C32) and Abu Dhabi (Opteron 6300-series, G34). A full listing of Opteron models 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

CFLAGS: -march=bdver3 -O2 -pipe
CHOST: x86_64-pc-linux-gnu
USE: mmx sse sse2 sse3 sse4 3dnow 3dnowext

The amd64-steamroller subarch supports the AMD steamroller microarchitecture, produced from early 2014. It is the successor to the AMD Piledriver microarchitecture. Steamroller APUs are available that use the FM2+ socket and FP3 socket (mobile.)

Desktop steamroller APUs include the 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 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

CFLAGS: -march=btver2 -O2 -pipe
CHOST: x86_64-pc-linux-gnu
USE: mmx sse sse2 sse3 sse4 3dnow 3dnowext

The amd64-jaguar (also called AMD Family 16h) subarch supports the 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 Playstation 4 and Xbox One, which each use custom 8-core Jaguar APUs. Socketed Jaguar APUs use the AM1 socket, and FT3 socket for mobile devices. G-series "system on a chip" (SoC) APUs are available for non-socketed devices such as tablets and embedded system boards.

Desktop Jaguar APUs include the 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.

64-bit Intel Processors

core2_64

CFLAGS: -march=core2 -O2 -pipe
CHOST: x86_64-pc-linux-gnu
USE: mmx sse sse2 sse3 ssse3

The core2_64 subarch supports 64-bit-capable Intel Core 2 Processors, which includes some processors of the Core and all processors of the Penryn microarchitecture. All "Core 2" branded processors are 64-bit-capable. These processors were introduced in July of 2006 and were phased out in July of 2011, in favor of Nehalem-based processors.

For a full list of 64-bit capable Core 2 processors, see this link.

The 64-bit capable Core 2-branded CPUs include: "Conroe"/"Allendale" (dual-core for desktops), "Merom" (dual-core for laptops), "Merom-L" (single-core for laptops), "Kentsfield" (quad-core for desktops), and the updated variants named "Wolfdale" (dual-core for desktops), "Penryn" (dual-core for laptops), and "Yorkfield" (quad-core for desktops). (Note: For the server and workstation "Woodcrest", "Tigerton", "Harpertown" and "Dunnington" CPUs see the Xeon brand.)

corei7

CFLAGS: -march=corei7 -O2 -pipe
CHOST: x86_64-pc-linux-gnu
USE: mmx sse sse2 sse3 ssse3 sse4

Beginning in November 2008, Intel launched the first Core i7 processor, codenamed Bloomfield, based on the Nehalem microarchitecture. With this launch, they also added to and modified the conventions of the Intel Core branding scheme. (Not to be confused with the Intel Core microarchitecture, which has only been supported by the processors sold under the Core2 brand. See core2_64.). This new naming scheme distinguishes between grades of processors rather than microarchitectures or design. Therefore, the corei7 subarch supports the Nehalem, Westmere, Sandy Bridge, Ivy Bridge, and Haswell microarchitectures under the follow brand names:

  • Intel Core i3 (entry-level consumer)
  • Intel Core i5 (mainstream consumer)
  • Intel Corei7 (high-end consumer/business)
  • Intel Xeon (business server/workstation)

atom_64

CFLAGS: -O2 -fomit-frame-pointer -march=atom -pipe -mno-movbe
CHOST: x86_64-pc-linux-gnu
USE: mmx sse sse2 sse3

The Intel Atom Processor is the common name for Intel's 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 Intel A100 series (Stealey), which was derived from the 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 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 Intel 64. If not all hardware supports 64-bit, then you must use the atom_32 subarch instead.
