summary
SteamOS ships an Arch-based, unlocked OS with a full KDE desktop and a gaming mode that runs Windows games via Proton/Wine adaptations; contributing concrete patches upstream: futex2 (futex_wv merged in Linux 5.16) to implement Windows-style wait-for-multiple-objects, case-insensitive ext4/f2fs support for Windows filenames, kernel knobs for split-lock handling, improved GPU reset and DRM signaling, RADV/ACO Vulkan driver work and Vulkan Video integration, the gamescope compositor, and an immutable A/B update flow plus Flatpak/portal selection fixes. These changes are upstreamed and in use on shipping devices.
