Collabora has published a blog
post about its work with Valve on Holo Core, which is a port of Arch Linux to
aarch64 to be used as the the operating system on Valve’s
64-bit Arm Steam Frame gaming system. Collabora has released the
sources,
binary
packages, and a container image for aarch64 devices. The post
describes some of the challenges in porting Arch Linux to a new
architecture, and what remains to be done:

Whilst the infrastructure developed to this point is capable of
building from first principles up until a point-in-time snapshot, the
next step is to build this into a system which can track Arch Linux as
it is developed. This work will serve as the basis of a
continuously-operating CI system capable of shadowing Arch Linux
itself. We will work with the upstream Arch Linux project to help Arch
with their efforts to port the distribution to aarch64 architecture
and work towards automated repeatable builds.

The post also includes instructions on how to create and test an
aarch64 build container on an x86_64 host, for users who would like to
follow along at home but lack a 64-bit Arm device.
