enricobuehler	d17aeefd1c	fix(windows-drivers): wstr! const->static (latent dangling .as_ptr) + record adapter-init ruleouts ... wstr! used `const W; W.as_ptr()` which points to a temporary dropped at the end of the statement (dangling) — fixed to `static W` (stable address). On-glass it did NOT change the IddCxAdapterInitAsync INVALID_PARAMETER, and a minimal SDR adapter (Flags=NONE + required callbacks only) fails identically, so the caps content + callbacks are NOT the blocker (offsets are byte-perfect vs C; sizes match the framework table; dispatch + device are correct). Config restored to FP16 + full HDR callbacks. Remaining suspects: IDARG_IN_ADAPTER_INIT layout, the missing DeviceContext (oracle always sets one), or a box/framework regression.

enricobuehler	1b0a13c25e	test(windows-drivers): offset-audit the IddCx caps — bindgen layout is byte-perfect ... IddCxAdapterInitAsync still INVALID_PARAMETER. Logged offset_of! for every IDDCX_ADAPTER_CAPS + IDDCX_ENDPOINT_DIAGNOSTIC_INFO field on the box: ALL match the expected C x64 layout exactly (caps Flags=4 MaxRate=8 MaxMon=16 Diag=24 Static=80; diag Trans=4 Friendly=8 Model=16 Manuf=24 HwVer=32 FwVer=40 Gamma=48). So the wdk-sys bindgen lays the struct out correctly — NOT a layout bug. The caps are byte-identical to C + match the framework size table + the oracle, yet rejected. Next: runtime compare vs the oracle (does it init an adapter on this box now?) + WDK-docs deep-dive. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-24 17:54:11 +00:00
enricobuehler	3d3dd3627c	feat(windows-drivers): STEP 3 on-glass — driver LOADS + runs full IddCx init chain ... Major on-glass progress on the RTX box. The all-Rust wdk-sys IddCx driver now LOADS under Secure Boot and runs the ENTIRE init chain: DriverEntry -> WdfDriverCreate -> driver_add -> IddCxDeviceInitConfig(0x0) -> WdfDeviceCreate -> CreateDeviceInterface -> IddCxDeviceInitialize -> D0Entry -> init_adapter. Findings: - Signing was a RED HERRING (the driver loads); std works in WUDFHost (DualSense uses it too). - THE unblock: link the iddcx **1.10** IddCxStub (build.rs now picks the highest version-aware), not 1.0 — the 1.0 stub lacks the version-table symbols AND its dispatch table mismatched the 1.10 framework, which made IddCxDeviceInitConfig return INVALID_PARAMETER. With 1.10 the whole chain runs. - Added a file/OutputDebugString logger (log.rs, matches the DualSense driver) — the driver was silent; this is how the chain was traced. - size.rs: framework_struct_size() reads the frameworks authoritative struct sizes from IddStructures[] (the config keeps size_of=208, validated working). - adapter.rs: version ptrs + ObjectAttributes(InheritFromParent) + FP16 + framework caps/diag/version sizes — matches the oracle. KNOWN WIP: IddCxAdapterInitAsync still returns INVALID_PARAMETER though caps match the framework size table (88/56/24) + the oracle exactly — likely a subtle wdk-sys bindgen field-layout detail in IDDCX_ADAPTER_CAPS/IDDCX_ENDPOINT_DIAGNOSTIC_INFO. CI gate (compile+link) stays green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-24 17:46:58 +00:00
enricobuehler	ad27174027	feat(windows-drivers): STEP 3 — IddCx adapter init (deferred D0, FP16 caps) ... adapter.rs: init_adapter(device) builds IDDCX_ADAPTER_CAPS (CAN_PROCESS_FP16, MaxMonitorsSupported=16, endpoint diagnostics with wstr! PCWSTR names) + IDARG_IN_ADAPTER_INIT and calls IddCxAdapterInitAsync; EvtDeviceD0Entry triggers it (idempotent), EvtIddCxAdapterInitFinished stashes the adapter in a OnceLock for later DDIs. zeroed()+named-field construction dodges the Default-derive + field-order questions. Compiles + links clean on the box (pf_vdisplay.dll 268KB). CI gate = compile+link; the on-glass load/enumerate gate needs the box + an INF + SwDeviceCreate (next).

enricobuehler	d0d31b1040	fix(windows-drivers): size_of config size (1.0 IddCxStub lacks the version table) + CI builds pf-vdisplay ... The versioned IDD_STRUCTURE_SIZE path referenced IddClientVersionHigherThanFramework/ IddStructureCount/IddStructures — LNK2019 unresolved, because the WDK links the iddcx 1.0 IddCxStub which lacks those (they are >=1.4). We target 1.10 against a current framework (higher==false) where size_of is exactly the versioned result, so use it directly (the surface-assert refs linked only because they were DCE-eliminated). pf-vdisplay now COMPILES + LINKS IddCxStub on the box (263,680B). Point windows-drivers.yml at the whole workspace + clear FORCE_INTEGRITY on pf_vdisplay.dll; drop the obsolete UINT diagnostic dump.

enricobuehler	4f10f3439d	feat(windows-drivers): pf-vdisplay STEP 2 — IddCx device skeleton ... DriverEntry -> driver_add builds the full IDD_CX_CLIENT_CONFIG (14 IddCx callbacks + PnP EvtDeviceD0Entry, all stubs with correct PFN signatures) sized via the ported IDD_STRUCTURE_SIZE! (size.rs), runs IddCxDeviceInitConfig -> WdfDeviceCreate -> WdfDeviceCreateDeviceInterface(the owned pf-vdisplay GUID, not SudoVDA) -> IddCxDeviceInitialize. callbacks.rs has all 14 + device_d0_entry; query_target_info implements HIGH_COLOR_SPACE. edid.rs salvaged verbatim from the oracle. proto gains interface_guid_fields() (u128 -> Windows GUID fields). Links IddCxStub (the CI gate); adapter/monitor/swapchain/IDD-push fill the stubs in STEP 3-6. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-24 16:12:20 +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).
