The '''amd64-steamroller''' sub-architecture (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]].

Layman is an "overlay" external repository management tool.
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 Berlin APUs, which are expected to be released some time in 2015.

Layman is an "overlay" external repository management tool.

Installation

# emerge layman

make.conf must source laymans overlays for emerge to pull in packages from external sources. This line needs to be below everything else in make.conf.

# echo "source /var/lib/layman/make.conf" >> /etc/portage/make.conf

Using Layman

Fetch, and display a list of overlays:

# layman -L

Add an overlay to your system:

# layman -a <overlay name>

Delete an overlay from your system:

# layman -d <overlay name>

Masking Overlay Packages

Overlays have the power to override distro packages. To avoid conflicts, mask everything in the overlay, and unmask the packages that are necessary to your system.

/etc/portage/package.mask - mask all packages in an overlay
*/*::overlay-name
/etc/portage/package.unmask - unmask packages to be used
cat-egory/pack-age1
cat-egory/pack-age2

Sync

Sync a specific overlays ebuilds:

# layman -s <overlay name>

Sync all overlays:

# layman -S

Sync all overlays via eix:

# eix-sync

Troubleshooting

Problem: Warning: an installed db file was not found at: ['/var/lib/layman/cache***.xml']

Solution:

# layman -L
