Full controller path for the SteamOS-like session, mirroring Sunshine byte-for-byte
(wire formats verified against moonlight-common-c + Sunshine source; ioctl numbers and
struct layouts verified by compiling against this box's <linux/uinput.h>, locked in with
const asserts):
- gamestream/gamepad.rs: decode MULTI_CONTROLLER (magic 0x0C, mixed BE-size/LE-body) incl.
the Sunshine buttonFlags2 extension (paddles/touchpad/Misc — our appversion already
advertises Sunshine, so clients send it) and CONTROLLER_ARRIVAL (0x55000004); build the
0x010B rumble plaintext (with the mandatory 4-byte filler). Unit-tested.
- inject/gamepad.rs: VirtualPad clones the kernel xpad identity ("Microsoft X-Box 360 pad",
045e:028e, exact button/axis codes + absinfo) so SDL/Steam/Proton match their built-in
mapping with zero config. GamepadManager creates/destroys pads from activeGamepadMask
(hotplug), emits button transitions + axes (+Y-up → evdev +Y-down negation, D-pad as
HAT0X/Y) per frame. Rumble: non-blocking FF pump answers UI_BEGIN/END_FF_UPLOAD/ERASE
(games block in EVIOCSFF until answered), tracks effects with replay expiry + FF_GAIN,
mixes to (low, high) motor levels, dedups.
- control.rs: channel_limit 8 → 0x30 — Moonlight sends gamepad input on ENet channel
0x10+n, so the old limit silently discarded ALL controller input. Gamepad events route to
the manager; rumble is sealed with the client's detected GCM scheme direction-flipped
(V2 marker 'H?', own seq counter) and sent on the control peer every service tick.
- scripts/60-lumen.rules: udev rule (Sunshine-style) granting the input group /dev/uinput.
Live validation needs the udev rule installed (root-only /dev/uinput on this box) + a
Moonlight client with a controller; everything else is gated and unit/static-checked.

# udev rules for the lumen streaming host (mirrors Sunshine's 60-sunshine.rules).
|
|
#
|
|
# Grants the `input` group access to /dev/uinput so the host can create virtual gamepads
|
|
# (one X-Box-360-class pad per connected Moonlight controller). `static_node` makes the node
|
|
# exist before the uinput module loads.
|
|
#
|
|
# Install:
|
|
# sudo cp scripts/60-lumen.rules /etc/udev/rules.d/
|
|
# sudo usermod -aG input $USER # then re-login (or reboot)
|
|
# sudo udevadm control --reload-rules && sudo udevadm trigger
