About Zaviya

Zaviya is an operating system for ARM handhelds and tablets, based on SteamOS for ARM. It provides Game Mode, the Steam client, a KDE desktop, PC games through FEX and Proton, emulation and Android apps.

Formerly known as Unofficial SteamOS ARM Port.

Why it exists

The ARM image made for Steam Frame targets a VR headset, so on a handheld several parts get in the way: services that keep crashing, an interface stuck on the slow cores, a GPU that does not clock up, and standby that drains the battery. Zaviya turns off what a handheld does not need and fixes the rest, then adds the hardware support, updater, app store and tools described in this documentation.
