+title: aarch64 build machines donated

+
+Good news!  We got a present for our build farm in the form of two
+SoftIron OverDrive 1000 aarch64 machines donated by ARM Holdings.  One
+of them is already running behind our new build farm, which distributes
+binaries from `https://berlin.guixsd.org`, and the other one should be
+operational soon.
+
+The OverDrive has 4 cores and 8Â GiB of RAM.  It comes in a fancy
+VCR-style case, which looks even more fancy with the obligatory
+stickers:

+
+A few months ago we reported on the [status of the aarch64
+port](https://www.gnu.org/software/guix/blog/2017/state-of-aarch64-on-guix/),
+which was already looking good.  The latest
+[releases](https://www.gnu.org/software/guix/blog/2017/gnu-guix-and-guixsd-0.14.0-released/)
+include a pre-built binary tarball of Guix for aarch64.
+
+Until now though, the project’s official build farms were not building
+aarch64 binaries.  Consequently, Guix on aarch64 would build everything
+from source.  We are glad that this is about to be fixed.  We will need
+to expand our build capacity for this architecture and for ARMv7 as
+well, and [you too can help](https://www.gnu.org/software/guix/donate/)!
+
+Thanks to ARM Holdings and in particular to Richard Henwood for
+contributing to our build infrastructure!
+
+#### About GNU Guix
+
+[GNUÂ Guix](https://www.gnu.org/software/guix) is a transactional package
+manager for the GNU system.  The Guix System Distribution or GuixSD is
+an advanced distribution of the GNU system that relies on GNU Guix and
+[respects the user's
+freedom](https://www.gnu.org/distros/free-system-distribution-guidelines.html).
+
+In addition to standard package management features, Guix supports
+transactional upgrades and roll-backs, unprivileged package management,
+per-user profiles, and garbage collection.  Guix uses low-level
+mechanisms from the Nix package manager, except that packages are
+defined as native [Guile](https://www.gnu.org/software/guile) modules,
+using extensions to the [Scheme](http://schemers.org) language.  GuixSD
+offers a declarative approach to operating system configuration
+management, and is highly customizable and hackable.
+
+GuixSD can be used on an i686, x86_64 and armv7 machines.  It is also
+possible to use Guix on top of an already installed GNU/Linux system,
+including on mips64el and aarch64.
