Download/Browse Funtoo Linux Subarches

This page provides an overview of Funtoo Linux sub-architectures (also called subarches) designed for quick and easy reference. Funtoo Linux provides optimized installation images for all sub-architectures listed below. Clicking on a particular subarch will bring you to a detail page where you can learn more about that subarch and download a stage3 for installation.


There are a couple of ways to identify the type of CPU you have. One option is to use the lscpu command:

# lscpu

If the lscpu command is unavailable, you can get similar information via /proc:

# cat /proc/cpuinfo | grep "^model name" | uniq
model name	: Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz

The cpuid command is another option and can provide other interesting information:

# emerge cpuid; cpuid | tail -n 1

Finding which microarch your hardware needs to use takes a little bit of searching. Take the chip name gathered, then google wiki chipname to find the wikipedia article for your chip. The right hand column of your processors wiki article will list the microarchitecture.

example: searching for "amd phenom wiki" returns this article & the article says its "Microarchitecture K10"


32-bit ARM Processors
armv7a_hardfpThis subarch supports the ARMv7-A architecture with hardware floating point. CPU support includes Cortex-A5 (with hardware FPU), Cortex-A7, A8, A9, A12, A15, A17, and Qualcomm Krait and other ARMv7-A CPUs.-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard
armv5teThis subarch supports the ARMv5 architecture with vector extensions, which is compatible with Pogoplug, SheevaPlug, TonidoPlug, Raspberry Pi, BeagleBoard, CuBox, PandaBoard, and TrimSlice.-O2 -pipe -march=armv5te
armv6j_hardfpThis subarch supports the ARM11 series processors, including compatible CPUs such as the Broadcom BCM2835 (Raspberry Pi).-O2 -pipe -march=armv6j -mfpu=vfp -mfloat-abi=hard


64-bit AMD Processors
amd64-bulldozerThe 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 K10 microarchitecture CPUs.-march=bdver1 -O2 -pipe
amd64-jaguarAMD jaguar microarchitecture debuted in mid-2013 and 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,-march=btver2 -O2 -pipe
amd64-k10The 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.-march=amdfam10 -O2 -pipe
amd64-piledriverThe 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.-march=bdver2 -O2 -pipe
amd64-steamrollerThe amd64-steamroller subarch supports the AMD steamroller microarchitecture, produced from early 2014. It is the successor to the AMD Piledriver microarchitecture.-march=bdver3 -O2 -pipe
