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.

Daniel Robbins has recently added the ability for the Portage tree to be extended and improved by the community. This allows Funtoo Linux users to contribute ebuilds of interest very easily, by simply committing their ebuilds to their own git-based portage repository. Your updated ebuilds are then auto-merged into the mainline Funtoo Portage tree every 12 hours. If you are interested in contributing to the Funtoo Linux Portage tree, please post an email to the [http://groups.google.com/group/funtoo-dev funtoo-dev mailing list] describing your overlay and its contents and we will consider the request.
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.
 
== Mini-Manifest Tree ==
 
Funtoo Linux provides two Portage tree repositories, available at the following location:
 
* http://github.com/funtoo/ports-2012
 
The first tree is a full Portage tree with full Manifests and ChangeLogs, and includes branches for Funtoo Linux as well as Gentoo Linux. The second tree is a minimized tree that contains only the unified Funtoo Linux Portage tree, all the ebuilds in the first tree, but contains "mini" Manifests (that only contain distfile digests) and has ChangeLogs removed. The first tree is used by Funtoo Linux internallly while the second tree is intended to be used by end-users, since it is much smaller.
 
== How the Tree is Built ==
 
New versions of the Funtoo Linux Portage tree are generated every 12 hours using a special merge script that combines the Gentoo Portage tree with the Funtoo Linux funtoo-overlay as well as other 3rd-party overlays. The overlays currently being merged are:
 
* http://github.com/funtoo/portage (gentoo.org branch)
* http://github.com/funtoo/funtoo-overlay (all ebuilds replacing those in Gentoo, including some eclass and profile patches)
* http://github.com/slashbeast/foo-overlay (all ebuilds being added, with two ebuilds replacing an upstream Gentoo version)
* http://github.com/adessemond/bar-overlay (all ebuilds replacing those in Gentoo)
* http://github.com/funtoo/flora [[Flora]] (all ebuilds being added, with no ebuilds replacing upstream Gentoo versions)
 
This list is likely to expand in the future.

Revision as of 07:03, December 20, 2014

This section lists the CPU-optimized Funtoo Linux builds currently available for download for amd64-jaguar.

No downloadable stage builds are currently available for this sub-architecture.

Architecture and Optimization

The following settings are applied to all stages for this subarch via Funtoo subarch profiles:

CHOSTx86_64-pc-linux-gnu
CFLAGS-march=btver2 -O2 -pipe


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.
