DKMS package that fetches the in-tree rtw89 source for the target kernel, applies the steam-frame patches, and builds/installs the patched RTL8852CU modules for the Valve Steam Frame wireless adapter. - dkms.conf: module list + install locations - build.sh: fetch (gregkh/linux) + patch + build + verify - register.sh: clone upstream patches, stage into /usr/src, dkms add/build/install GPL-2.0-only.
rtw89-steam-frame dkms
DKMS wrapper for the patched Realtek rtw89 driver used by the Valve Steam Frame
wireless adapter (28de:2432, RTL8852CU).
It builds the in-tree rtw89 source for whatever kernel you run (fetched from
gregkh/linux), applies the steam-frame patches (pulled at register time via git
from Davenport-Physics/rtw89-steam-frame),
and auto-rebuilds on every kernel upgrade through the Arch DKMS pacman hooks.
Why
The Frame advertises a 6 GHz VLP power class and the stock driver honors it, capping the dongle at 7/4 dBm (1TX/2TX) — roughly 10 dB below what the Windows driver uses. That deficit caused MAC-layer retry storms and bursty micro-stutters in VR streaming (see SteamVR-for-Linux#965).
reg6_pwr_override=1 switches the adapter to the LPI table (12/11 dBm at 160 MHz),
which on this system removed the missed-frame stalls even at ~1.8x the previous load.
disable_2ghz=Y additionally disables the useless 2.4 GHz band (and the scan-offload
USB resets associated with it).
Install / re-register
./register.sh # As root
This clones upstream, stages /usr/src/rtw89-steam-frame-0.1, and runs
dkms add/build/install for the current kernel. After that, the Arch pacman hooks
(/usr/share/libalpm/hooks/70-dkms-*) rebuild it automatically on every kernel update.
Optional env overrides: RTW89_UPSTREAM, RTW89_UPSTREAM_REF, RTW89_KVER.
Preconditions
linux-headersinstalled and kept in sync withlinux.- Network access at (re)build time — the kernel's rtw89 source and the patches are both fetched over HTTPS.

Module parameters
Add this to modprobe.d, e.g. /etc/modprobe.d/rtw89-steam-frame.conf:
`options rtw89_core reg6_pwr_override=1 disable_2ghz=Y`
You might also want to disable advanced power management if not done so already (also supported by in-kernel driver):
`options rtw89_core disable_ps_mode=Y`
