enricobuehler	e2f004589c	feat(windows-drivers): STEP 6 — IDD-push FramePublisher (driver) + host migration to proto::frame ... The driver now publishes each acquired swap-chain surface into the host-created shared ring (the IDD-push path) — the full glass-to-glass transport is code-complete. Both sides use the canonical pf_vdisplay_proto::frame layout (lockstep by compile-error, not "must match" comments). Driver compiles + LOADS on-glass (adapter inits, Status=OK; no regression — the publisher is dormant until a frame is acquired); host cargo check green; adversarially reviewed (no blockers — token layout, keyed-mutex key 0, names by target_id, and the format guard all match the host consumer). - new driver frame_transport.rs: FramePublisher OPENS the host ring by target_id (OpenFileMapping header + magic Acquire readiness gate + OpenEvent + OpenSharedResourceByName RING_LEN keyed-mutex textures), writes its render LUID + DRV_STATUS back into the header; publish() is NON-BLOCKING (round-robin 0ms try-acquire -> CopyResource -> ReleaseSync -> FrameToken::pack store Release -> SetEvent; drops the frame if every slot is busy or the surface format != the ring format). Manual handle/view cleanup on every try_open early return; RAII Drop (slots -> unmap -> CloseHandle). Layout/consts/names/token all from pf_vdisplay_proto::frame. - swap_chain_processor.rs run_core: lazy rate-limited attach (every ~30 frames) + is_stale re-attach (mid-session HDR ring recreate); publishes buffer.MetaData.pSurface via IDXGIResource::from_raw_borrowed (preserves IddCx's refcount) BEFORE IddCxSwapChainFinishedProcessingFrame. run/run_core gain the render LUID; callbacks.rs assign_swap_chain passes it. - host idd_push.rs migrated onto pf_vdisplay_proto::frame (deleted the hand-rolled SharedHeader / MAGIC / VERSION / RING_LEN / DRV_STATUS_* / name fns / token packing) — pure refactor, byte-identical, no behavior or gating change. DebugBlock + DXGI_SHARED_RESOURCE_RW kept local (not in the proto). - driver windows crate gains Win32_System_Memory (MapViewOfFile/OpenFileMappingW/...); rustfmt'd the whole driver workspace (incl. wdk-probe — fmt-only). Built via the ultracode flow: STEP-6 map workflow -> agent-implement -> box build (driver + host both green; caught nothing this time) -> adversarial-verify-agent (no blockers) -> FrameToken::pack hardening -> deploy (loads). Glass-to-glass frame validation awaits a composited session (per the parity finding: this headless box yields 0 frames for the proven SudoVDA path too). FOLLOW-UPs: port the optional Global\pfvd-dbg DebugBlock triage channel to the new driver; STEP 7 HDR; STEP 8 drop SudoVDA.

enricobuehler	3fbabc854c	feat(windows-drivers): IddCx link probe — call init DDIs via table dispatch ... First USE of the iddcx binding: a minimal table-dispatch (src/iddcx_rt.rs) over wdk_sys::iddcx — IddFunctions[_IDDFUNCENUM::<Name>TableIndex] cast to PFN_*, IddDriverGlobals as implicit arg 1 (the WDF model; ModuleConsts i32 index, not the oracle NewType .0). The probe EvtDeviceAdd now calls IddCxDeviceInitConfig → WdfDeviceCreate → IddCxDeviceInitialize → IddCxAdapterInitAsync, exports IddMinimumVersionRequired=4, and build.rs links IddCxStub (globbed from the SDK Lib dir that ships iddcx). CI gate = compile + link IddCxStub. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-24 15:18:48 +00:00
enricobuehler	d3e4ea0118	feat(windows-drivers): driver workspace + wdk-probe on windows-drivers-rs (M1) ... Stand up packaging/windows/drivers/ — the unified driver workspace on crates.io windows-drivers-rs (wdk 0.4.1 / wdk-sys + wdk-build 0.5.1), retiring the dev-box ../../crates/wdk* path-deps. First member: wdk-probe, the smallest UMDF2 driver (DriverEntry -> WdfDriverCreate -> EvtDeviceAdd -> WdfDeviceCreate) that force-links the shared pf-vdisplay-proto ABI crate. It validates on the runner: wdk-sys bindgen + WDF stub link against the WDK + LLVM, the cross-workspace no_std proto path-dep, and the produced DLL's PE FORCE_INTEGRITY bit. windows-drivers.yml gains a driver-build job: cargo build -p wdk-probe (pinning Version_Number=10.0.26100.0) + a PE inspection that prints whether /INTEGRITYCHECK is set — the M0 self-signed-load question.
