enricobuehler	e2c9bfd3d9	feat(windows): pf-vdisplay IDD-push — HDR + pipelined zero-copy capture ... HDR (display-driven, matching the WGC path): - CTA-861.3 HDR EDID (BT.2020 primaries + HDR Static Metadata block) so Windows offers "Use HDR" on the virtual display. The host FOLLOWS the display's live advanced-color state, recreating the shared ring at the matching format (FP16 in HDR / BGRA in SDR) on a toggle — no freeze. - Always emit Main10/BT.2020-PQ Rgb10a2 while the display is HDR; the client auto-detects PQ from the HEVC VUI (clients under-report VIDEO_CAP_10BIT). Generic HDR10 mastering SEI on every IDR. - Generation-tagged `latest` (gen<<40|seq<<8|slot) + driver `is_stale` re-attach kill the toggle-time garbage frame and any stale-ring read. Perf: - Pipeline the encode loop (Capturer::pipeline_depth; IDD-push = 2): submit N+1 before polling N so the convert/copy on the 3D engine overlaps the NVENC encode of N on the ASIC. PUNKTFUNK_IDD_DEPTH overrides (1 = synchronous). - Rotating host output ring (OUT_RING) so the in-flight encode and the next convert never touch the same texture. - HDR converts directly from the keyed-mutex slot's SRV into the output ring (drops the redundant slot->fp16 scratch copy); SDR copies the BGRA slot in. The slot mutex is held only across the convert/copy, not the encode. RING_LEN 3->6 for publish headroom. - Capture-health diagnostic: new_fps vs repeat_fps under PUNKTFUNK_PERF (a low new_fps at a high send rate means the source isn't compositing, not an encode stall). Validated live on the RTX box: 5120x1440@240 HDR streams; driver composes ~180 new fps, encode 240 fps @ ~4.3 ms p50.

enricobuehler	e27abc065e	feat(windows): pf-vdisplay CLEAR_ALL — reap orphaned virtual monitors on startup ... The "5-6 stale monitors that never tear down" failure (also seen with SudoVDA): an orphan from a crashed/killed previous host lingers because the driver watchdog is kept reset by a still-pinging new session, so it never fires for the orphan. - Driver (pf-vdisplay control.rs): new IOCTL_CLEAR_ALL (0x804) -> tear down every monitor. A pf-vdisplay extension; SudoVDA returns invalid for it (ignored), so the host can issue it unconditionally. - Host (vdisplay/sudovda.rs): send IOCTL_CLEAR_ALL once on startup (best-effort) to reap orphans before creating ours; and surface a failing keepalive PING (the old `let _ =` swallowed it, masking a lost control handle).

enricobuehler	d39da4bc06	feat(windows): pf-vdisplay — all-Rust IddCx virtual display (replaces SudoVDA) ... P1 done: a pure-Rust UMDF2 IddCx driver, drop-in compatible with the host's existing vdisplay/sudovda.rs control plane (the {e5bcc234} interface + the SudoVDA IOCTL ABI), so the host drives it unchanged. Validated streaming on glass at 5120x1440@240 — steady 240 fps, ~2.4 ms encode, clean teardown, full parity with SudoVDA. - Vendored wdf-umdf-sys / wdf-umdf bindgen crates (MIT, from virtual-display-rs) + the SDK-version build.rs fix that resolves the IddCxStub lib path by the WDK version actually containing um\x64\iddcx, not the max base SDK. - pf-vdisplay crate: entry/callbacks/context/control/monitor/edid/ swap_chain_processor. Our OWN 128-byte EDID (manufacturer PNK, product punktfunk — no SudoVDA bytes), a real swap-chain drain (faithful vdd port, required so DWM keeps compositing), the SudoVDA-compatible IOCTL control plane (ADD/REMOVE/PING/GET_WATCHDOG/GET_VERSION/SET_RENDER_ADAPTER) + a watchdog that tears down orphaned monitors when the host stops pinging. - deploy-dev.ps1: stage + sign + stampinf (date.time DriverVer) + Inf2Cat + install, codifying the "bump DriverVer or pnputil keeps the old binary" gotcha. - docs/windows-virtual-display-rust-port.md: investigation, the on-glass validation, and the two traps that cost time (Session-0 measurement + accumulated device-state needing a reboot).
