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 build step.

|

# Fetches the in-tree rtw89 source for the *target* kernel from gregkh/linux,
|

# applies the steam-frame patches, and builds in the current directory.

# Invoked by DKMS: CWD = DKMS build dir, $kernelver exported by DKMS.

# Also runnable standalone: kernelver=7.2.8-arch1-2 bash build.sh

# Exit non-zero on any failure so DKMS marks the build failed (module not
|
|
# installed for that kernel -> kernel keeps its stock rtw89). See plan for

# the modprobe.d recovery note.
