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).

//! pf-vdisplay — the all-Rust UMDF IddCx virtual-display driver (M1 step-2 rewrite, on wdk-sys + the
|
|
//! owned pf-vdisplay-proto ABI). See docs/windows-host-rewrite.md §14 for the full port plan.
|
|
//!
|
|
//! STEP 2: the IddCx driver SKELETON — DriverEntry → driver_add builds the full `IDD_CX_CLIENT_CONFIG`
|
|
//! (14 IddCx callbacks + the PnP `EvtDeviceD0Entry`, all stubs) sized via the versioned
|
|
//! [`size::idd_cx_client_config_size`], runs `IddCxDeviceInitConfig` → `WdfDeviceCreate` →
|
|
//! `WdfDeviceCreateDeviceInterface`(the owned pf-vdisplay GUID) → `IddCxDeviceInitialize`, and exports
|
|
//! `IddMinimumVersionRequired`. This links `IddCxStub` (the CI gate). The real adapter init (STEP 3),
|
|
//! control plane + monitor/modes (STEP 4), and swap-chain/IDD-push (STEP 5-6) fill the stubs in.
