@subsection Hardware Considerations
@cindex hardware support on GuixSD
GNU@tie{}GuixSD focuses on respecting the user's computing freedom. It
builds around the kernel Linux-libre, which means that only hardware for
which free software drivers and firmware exists is supported. Nowadays,
a wide range of off-the-shelf hardware is supported on
GNU/Linux-libre---from keyboards to graphics cards to scanners and
Ethernet controllers. Unfortunately, there are still areas where
hardware vendors deny users control over their own computing, and such
hardware is not supported on GuixSD.
@cindex WiFi, hardware support
One of the main areas where free drivers or firmware is lacking is WiFi
devices. WiFi devices known to work include those using Atheros chips
(AR9271 and AR7010), which corresponds to the @code{ath9k} Linux-libre
driver, and for which free firmware exists and is available
out-of-the-box on GuixSD, as part of @var{%base-firmware}
(@pxref{operating-system Reference, @code{firmware}}).
@cindex RYF, Respects Your Freedom
The @uref{https://www.fsf.org/, Free Software Foundation} runs
@uref{https://www.fsf.org/ryf, @dfn{Respect Your Freedom}} (RYF), a
certification program for hardware products that respect your freedom
and your privacy and ensure that you have control over your device. We
encourage you to check the list of RYF-certified hardware.
Another useful resource is the @uref{https://www.h-node.org/, H-Node}
web site. It contains a catalog of hardware devices with information
about their support in GNU/Linux.
