Funtoo currently has no plans to migrate or adopt systemd as it's default init system. This does '''not''' prevent you from using systemd on your system. [https://coreos.com/ CoreOS], for example, is a systemd based system build on Gentoo.

The '''amd64-jaguar''' (also called AMD Family 16h) subarch debuted in mid-2013 and 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.
  
For users not seeking to use systemd, that is, most Funtoo users, this page will serve both as the Funtoo development team's planning for the future, and information on how to avoid systemd in your system.

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.

This is a tiny daemon that can be used to control the host name and related machine meta data from user programs. It currently offers access to five variables:
+
 
+
* The current host name (Example: dhcp-192-168-47-11)
+
* The static (configured) host name (Example: lennarts-computer)

The daemon provides both a C library interface (which is shared with logind) as well as a D-Bus interface. The library interface may be used to introspect and watch the state of virtual machines/containers. The bus interface provides the same but in addition may also be used to register or terminate machines.

A system service that may be used to synchronize the local system clock with a remote Network Time Protocol server. It also saves the local time to disk every time the clock has been synchronized and uses this to possibly advance the system realtime clock on subsequent reboots to ensure it monotonically advances even if the system lacks a battery-buffered RTC chip.

amd64-jaguar (Sub-architecture)

Note

This page describes a sub-architecture for Funtoo Linux, which is a particular set of optimizations that is used for a Funtoo Linux build.

The amd64-jaguar (also called AMD Family 16h) subarch debuted in mid-2013 and 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.
