enricobuehler	95a08e99c3	feat(host/windows): seal the host↔driver channels (frame + gamepad, proto v2) ... Frame ring (pf-vdisplay) and both gamepad SHM channels move off named Global\ objects (openable by any sibling LocalService) to UNNAMED sections/events whose handles the host DuplicateHandles into the driver's verified WUDFHost with least access — frame delivery over the SYSTEM+admins-only IOCTL_SET_FRAME_CHANNEL, pads over a 32-byte named bootstrap mailbox (pid + handle value only, DoS-bounded; HID minidrivers have no control device). Driver-validated pad_index kills cross-pad redirects; v1↔v2 mixes fail closed with diagnosis logs on both sides. Sibling-LocalService denial proven empirically (design/idd-push-security.md, design/gamepad-channel-sealing.md). Driver-side raw ops now live behind pf-umdf-util (checked shm accessors, the forbid(unsafe_code) ChannelClient state machine, WDF request tokens) — the pad drivers' logic is 100% safe Rust; whole drivers workspace clippy-gated in CI. driver install --gamepad now sweeps SWD\punktfunk phantom devnodes: a re-created SwDevice REVIVES the old devnode with its previously-bound driver (never re-ranks), so an upgrade otherwise leaves the old driver serving — or, across the v1→v2 fence, a dead pad (found live on the RTX box). On-glass validated on the RTX 4090 box: frame path 7007 frames p50 2.06 ms cross-machine; DualSense + XUSB "sealed pad channel mapped"/proto=2 attach via both the test harness and a real streaming session; phantom-sweep repro.

enricobuehler	a755d6eab7	chore(windows-drivers): deny(unsafe_op_in_unsafe_fn) on the driver crates (audit §8 P0) ... Lock in the explicit-unsafe-block discipline so a fn-level 'unsafe' never silently blesses its whole body (the per-site // SAFETY: comments already landed in STEP 8). Builds clean on the RTX box — no fallout. The host-wide unsafe-lint sweep + clippy::undocumented_unsafe_blocks (hundreds of blocks across Linux+Windows) are a larger dedicated follow-up.

enricobuehler	788e4acbb5	feat(windows-drivers): STEP 1 — wdk-iddcx with all 11 IddCx DDI wrappers ... Graduate the proven iddcx_rt.rs dispatch into wdk-iddcx + add the full DDI set the pf-vdisplay driver needs: DeviceInitConfig/Initialize, AdapterInitAsync, MonitorCreate/Arrival/Departure, AdapterSetRenderAdapter (void-returning DDI — its PFN returns ()), SwapChainSetDevice/ReleaseAndAcquireBuffer2/FinishedProcessingFrame. One dispatch macro pins each (_IDDFUNCENUM index, PFN_* type) pair exactly once (the only place table dispatch can be UB). Box-compiles green; IddCxStub link gets validated when pf-vdisplay (cdylib) consumes it in STEP 2. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-24 15:55:45 +00:00
enricobuehler	d7a9fbf0b6	feat(windows-drivers): pf-vdisplay STEP 0 scaffold + std-under-UMDF link gate ... M1 step 2 begins. Add the wdk-iddcx (lib, re-exports wdk_sys::iddcx) + pf-vdisplay (cdylib) workspace members. pf-vdisplay STEP 0 = DriverEntry + WdfDeviceCreate skeleton + a #[used] _std_link_gate forcing std::thread + OwnedHandle to link, so the build proves the std surface resolves under the wdk-build UMDF link settings (kernel32 is /NODEFAULTLIB - std must come via OneCoreUAP). If std fails to link here, the SwapChainProcessor worker-thread design needs a CreateThread shim before any callback work (port-plan critique gap #9).
