EvtIddCxDeviceIoControl now dispatches the pf-vdisplay-proto control plane (new
src/control.rs): IOCTL_GET_INFO writes InfoReply{protocol_version, watchdog_timeout_s}
(the host asserts the version + fails loudly on mismatch), IOCTL_PING bumps the watchdog
keepalive. ADD/REMOVE/SET_RENDER_ADAPTER/CLEAR_ALL are dispatched but stubbed
(STATUS_NOT_IMPLEMENTED) pending create_monitor + the real mode DDIs (next). Unknown
IOCTLs -> STATUS_NOT_FOUND. Builds CI-green; warnings are the *2/HDR stubs (STEP 7) +
the stored adapter handle (read by create_monitor, 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.
