enricobuehler	b0c82333d2	feat(gamepad): pure-user-mode Windows DualShock 4 + Xbox 360 (drop ViGEm) + installer + multi-pad ... Windows virtual gamepads now have zero external dependencies - ViGEmBus is removed. - DualShock 4: Windows UMDF backend (inject/dualshock4_windows.rs + dualshock4_proto.rs), reusing the DualSense SwDeviceCreate game-detection identity fix. The one UMDF driver serves the DS5 or DS4 identity/descriptor/features/strings per a device_type byte the host stamps into shared memory. Driver also gains IOCTL_HID_GET_STRING and a 41-byte calibration feature. - Xbox 360: a new UMDF2 XUSB companion driver (packaging/windows/xusb-driver/) that registers GUID_DEVINTERFACE_XUSB and answers the buffered XInput IOCTLs from a shared section, so classic XInputGetState/SetState work with no kernel bus driver. inject/gamepad_windows.rs is rewritten to drive it and the vigem-client dependency is removed. Xbox One folds to the 360 XInput path. - Installer: vendor + pnputil-install the three UMDF drivers (packaging/windows/gamepad-drivers/ + install-gamepad-drivers.ps1, wired into pack-host-installer.ps1 + punktfunk-host.iss). - Multi-pad: the host stamps each pad index into the device Location (pszDeviceLocation); the driver reads it via WdfDeviceAllocAndQueryProperty to map its own *-shm-<index>, with UmdfHostProcessSharing=ProcessSharingDisabled giving each pad its own host (per-pad statics). Validated live on the Windows host: Cyberpunk native DualSense detection, DS4 identity + descriptor, XInputGetState + rumble round-trip, two pads -> two distinct XInput slots, and a full installer build.

enricobuehler	01dc0b616c	refactor(windows): trim the inert IOCTL channel from the DualSense driver ... The host<->driver channel is the shared-memory section (hidclass blocks the device stack and UMDF has no control device), so the first-attempt in-driver IOCTL channel never fired. Remove it: the custom device interface, IOCTL_PFDS_SET_INPUT/GET_OUTPUT, the output queue, and the on_set_input/complete_one_read/deliver_output helpers. The driver keeps the HID handshake, the 8ms read timer fed from the shared section, and on_output_report publishing the game's 0x02 to the section. Rebuilt + reloaded + the channel still verifies both directions live on the RTX box. Also list `pf_dualsense` as a second hardware id (alongside `root\pf_dualsense`) so the host's SwDeviceCreate'd software device binds the same driver as a devgen one.

enricobuehler	aa159df33f	feat(windows): Rust UMDF virtual DualSense driver + shared-memory host channel ... A self-authored UMDF2 HID minidriver (packaging/windows/dualsense-driver) that presents a virtual Sony DualSense (VID 054C/PID 0CE6) on Windows — adaptive triggers / lightbar / rumble that ViGEm structurally cannot deliver. Validated live on an RTX box (Win11 25H2, Secure Boot ON): the self-signed driver loads, Steam recognizes it as a genuine DualSense, and a game's 0x02 output report reaches the driver. The host<->driver channel is a named shared-memory section (Global\pfds-shm-<idx>) the host creates and the driver maps from its timer: input report 0x01 host->driver, output report 0x02 driver->host — input and output proven both directions live. This bypasses hidclass, which gates both a custom device interface and custom IOCTLs on the HID node, and UMDF has no control device. Built in Rust on microsoft/windows-drivers-rs. The load wall was the PE FORCE_INTEGRITY bit that wdk-build sets via /INTEGRITYCHECK (forces a CI-trusted page-hash signature a self-signed cert cannot satisfy) — cleared post-build. See packaging/windows/dualsense-driver/README.md for the build/sign/install recipe. Deferred: SwDeviceCreate per-session device lifecycle; removing the inert in-driver IOCTL-channel code; full on-glass session test.
