CONFIRMED
Valve’s Steam Frame headset, codename “Deckard,” has been upstreamed to the mainline Linux kernel as part of the Linux 7.4 SoC merge, Phoronix and TechPowerUp report. The catch: the merged code covers only initial board bring-up, so nobody should expect to flash Fedora onto the headset and start playing VR next month.
What we know
According to Phoronix and TechPowerUp, the Steam Frame landed in mainline Linux on Sunday, Oct 25, 2026, during the SoC merge for the Linux 7.4 cycle. Neil Armstrong of Linaro authored the patches, and TechPowerUp says he submitted them on behalf of Valve. The patch text describes an “initial DeviceTree” for a headset built on Qualcomm’s Snapdragon 8 Gen 3 (SM8650).
The scope is narrow. Per the reports, the patch covers reserved memory, regulators, GPIO keys, PMIC functions and ADC channels, UFS storage, USB gadget mode, WCN7850 Wi-Fi 7 and Bluetooth, I2C and basic peripherals, and the SD card slot. Phoronix adds that the bootloader starts Linux in EL2, so some EL1 and DSP-related nodes were dropped and the reserved-memory map had to be defined by hand.
Phoronix says the most polished, full-featured support still lives in Valve’s downstream SteamOS kernel builds, and TechPowerUp says mainline is not yet feature-complete. TechPowerUp also notes the headset has run on those downstream builds since its September launch.
On the PC side, Valve’s own words are clearer. Mixed News reports that Valve replied on its official SteamVR-for-Linux GitHub tracker on Oct 3, 2026, saying many Linux configurations already support streaming to Steam Frame using Steam Link. The same reply says the wireless adapter needs SteamOS 3.9+ or Linux kernel 7.2+, and that additional patches are working their way through various packages to better support the dongle. Valve named no package, kernel version or timeframe.
Mixed News also points out the gaps: Valve’s support guide still says Windows only, SteamOS 3.9 was only on beta and preview channels at the time (3.9.2 Beta from Sep 25 was newest, stable sat at 3.8.28), and kernel 7.2 is newer than most distributions ship by default.
What is rumored
Mixed News reports that Valve’s Steam Frame kernel sources were mirrored on GitHub on Oct 13-14, 2026, as 24 repositories under an “evlaV” organisation. The “deckard-linux” fork has a default branch called sm8650-7.2 with Valve engineers’ names on the commits, and Mixed News says it lines up with the linux-72-deckard package in Valve’s public Deckard source index. The mirror is unofficial, though checkable against that index. It is also the downstream SteamOS kernel, not the mainline 7.4 work.
The bigger claim, that mainline support could or should make it easier for Fedora, Arch, Ubuntu and others to run on the Steam Frame as a SteamOS alternative, is analysis from Phoronix and TechPowerUp. Phoronix has a long record of tracking kernel merges, but this angle is inference. Valve has not said anything about supporting other operating systems on the headset.
What we don’t know yet
We don’t know whether Valve intends to allow or support alternative operating systems on the Frame. The patches don’t tell us whether the bootloader is unlockable for end users. There’s no word on when tracking, display, GPU and other VR-critical pieces might reach mainline, or whether they will at all. Valve also hasn’t said which packages the dongle patches are headed for, or when its support guide will stop saying Windows only.
What it means
For Linux PC players, the practical news is Valve’s tracker reply: streaming to Steam Frame works on many setups today if you’re on SteamOS 3.9 beta or a 7.2+ kernel. That’s a real signal, even if official documentation lags.
The mainline merge is a meaningful sign of openness, but treat it as foundation work. Linux 7.4 is still in development, and as a pbxscience summary notes, support only reaches users through the stable release and later distribution kernels. Booting a generic distro is a long way from running SteamVR on one. For now, SteamOS remains the only full-featured way to use the headset.
