enricobuehler	85bc5b9a3f	refactor(host/W6.2): extract the Linux zero-copy GPU plumbing into the pf-zerocopy leaf crate ... linux/zerocopy/* (CUDA context/buffers + EGL/Vulkan dmabuf import + the isolated import worker) and linux/dmabuf_fence.rs move wholesale into crates/pf-zerocopy, so the coming pf-frame vocabulary crate (FramePayload::Cuda owns a DeviceBuffer) and the pf-encode/pf-capture subsystem crates can reach the GPU plumbing without the host orchestrator in between (plan §W6). Content stays Linux-only; the crate compiles to an empty lib elsewhere, so dependents carry a plain dependency. drm_fourcc deliberately does NOT move: it consumes the frame vocabulary (PixelFormat), which sits ABOVE pf-zerocopy — it lives with capture for now and moves into pf-frame next. cuda's ffi re-export bumps pub(crate)->pub (the raw CUdeviceptr vocabulary is consumed across the crate boundary by the encode backends). A crate::zerocopy shim module keeps every existing path valid until capture/encode themselves move out. Verified: Linux clippy -D warnings (pf-zerocopy --all-targets + host nvenc,vulkan-encode,pyrowave --all-targets) + 17/17 pf-zerocopy tests + 321/321 host tests; Windows clippy nvenc,amf-qsv --all-targets Finished exit 0.

enricobuehler	6ea036766a	refactor(host/W6.1): extract GPU vendor/adapter detection into the pf-gpu leaf crate ... Fourth de-coupling for the host crate carve (plan §W6.1 leaf). gpu.rs (inventory, selection preference, active-session accounting — deps only pf-host-config + pf-paths, no subsystem refs) moves to a new pf-gpu leaf so pf-encode/pf-capture/pf-vdisplay can consult the selected GPU without an orchestrator edge. ~50 crate::gpu:: sites repoint to pf_gpu::; the ~30 pub(crate) items become pub (crate API). assign_ids gets a macOS-only allow(dead_code) (used only by the Linux/Windows enumerate arms). Verified: Linux (home-worker-5) clippy -p pf-gpu -p punktfunk-host --all-targets -D warnings + pf-gpu tests (12 pass); Windows (192.168.1.158) clippy --features nvenc,amf-qsv --all-targets green.

enricobuehler	3495d189e1	refactor(host/W6.1): extract the config() global into the pf-host-config leaf crate ... Third de-coupling for the host crate carve (plan §W6.1 leaf). HostConfig + the config() OnceLock (config.rs, pure std, zero deps) move to a new pf-host-config leaf so every subsystem crate (pf-encode/pf-capture/pf-vdisplay/pf-gpu) can read process config WITHOUT depending on the orchestrator. 34 crate::config::config() call sites across 19 files repoint to pf_host_config::config(). thread_qos stays in the host for now (it calls session_tuning::on_hot_thread — its own leaf-ification rides the encode carve). Granular-crate decision (supersedes the plan's single pf-media): split capture/encode/ vdisplay into separate crates rather than one broad crate — the capture↔encode cycle is broken by a shared frame-types leaf, and vdisplay→encode (can_open_another_session) is a legal one-way edge since encode never references vdisplay. Verified: Linux (home-worker-5) clippy -p pf-host-config -p punktfunk-host --all-targets -D warnings; Windows (192.168.1.158) clippy --features nvenc,amf-qsv --all-targets green.

enricobuehler	c42ce88921	refactor(host/W6.1): extract secret/config-dir helpers into the pf-paths leaf crate ... Second de-coupling for the host crate carve (plan §W6.1 leaf). config_dir / create_private_dir / write_secret_file (+ the Windows DACL helpers) were pub(crate) in the gamestream junk drawer, yet consumed by vdisplay, stats, gpu, library, mgmt_token, native_pairing and the Windows service — many of which become pf-media / pf-vdisplay, for which crate::gamestream would be an illegal upward edge. New leaf crate pf-paths (pure std + tracing) owns them; ~40 call sites across 14 files repoint to pf_paths::. gamestream keeps only its own concerns. Verified: Linux (home-worker-5) clippy -p pf-paths -p punktfunk-host --all-targets -D warnings + tests (347 pass, incl. secrets_are_written_owner_only); Windows (192.168.1.158) clippy --features nvenc,amf-qsv --all-targets green.

enricobuehler	2e3208f75e	refactor(host/W6.0): drop gamestream BTN_* aliases; injectors read core directly ... Finishes the gamepad-vocabulary un-coupling (plan §W6.0): the Linux uinput button map now names BTN_* straight from punktfunk_core::input::gamepad instead of the crate::gamestream re-export aliases, so pf-inject will carry no edge into the gamestream junk drawer for gamepad constants. Removes the now-dead alias block; the wire-bit pinning test (gamepad_wire_bits_are_pinned) pins core directly (equally strong — core is the single source). gamestream keeps only the decode path, which imports the types from core. Verified: Linux (home-worker-5) clippy --all-targets -D warnings + gamepad tests green; Windows (192.168.1.158) clippy -p punktfunk-host --features nvenc,amf-qsv --all-targets green.

enricobuehler	47587827ec	refactor(host/W6.0): hoist GamepadEvent/GamepadFrame to punktfunk_core::input ... First de-coupling for the host crate carve (plan §W6.0 / §2.4): the GameStream (Moonlight-plane) decoded controller types were defined in gamestream/gamepad.rs — the "junk drawer" — yet consumed 18× by the platform-neutral input injectors AND by the Moonlight decode path. Once inject becomes pf-inject, reaching them via crate::gamestream would be an illegal upward edge. Move the two types to core::input (below both planes; inject already depends on core) and repoint every consumer. Also consolidate the duplicated MAX_PADS onto the existing core::input::MAX_PADS. The gamestream BTN_* const aliases stay for now (separate follow-up); decode()/rumble/tests remain in the Moonlight plane, now importing the types from core. Verified: Linux (home-worker-5) clippy -p punktfunk-core -p punktfunk-host --all-targets -D warnings + gamepad tests green; Windows (192.168.1.158) clippy -p punktfunk-host --features nvenc,amf-qsv --all-targets green (the inject/windows/* consumers compile).

enricobuehler	f2a58f3a91	feat(host/library): external provider API — declarative reconcile (M4) ... External game-library providers become first-class (RFC §8): a plugin computes its desired title list and PUTs it — the host owns the diff. - CustomEntry gains `provider` + `external_id` (API-set only; never on manual entries). GameEntry surfaces `provider` for console attribution and the new `GET /library?provider=` filter. - PUT /api/v1/library/provider/{p}: atomic declarative reconcile keyed on the provider's `external_id` — host ids stay stable across syncs, orphans drop, manual entries and other providers are never touched, an empty array clears the set. Validated: provider id [a-z0-9._-] (`manual` reserved), unique non-empty external_ids. - DELETE /api/v1/library/provider/{p}: clean uninstall, returns the removed count. - Ownership is unambiguous both ways: manual CRUD now returns 409 for a provider-owned entry (MutateOutcome::ProviderOwned) instead of letting an edit be silently clobbered at the next sync. - library.changed now carries the mutating source (`manual` or the provider id) — hooks and the SDK filter on it. - Spec + SDK schemas regenerated; sdk/examples/provider-sync.ts is the provider-plugin skeleton. 347 host tests green (pure reconcile: stable ids, orphan drop, idempotence, bystanders untouched; name/payload validation; route 400s) + 11 SDK tests. Live-verified end to end THROUGH the SDK against a real host: sync → filtered list → manual-delete 409 → re-sync with stable id + orphan drop → uninstall (removed=2), with three library.changed(source=romm) events observed on the live stream.

enricobuehler	aaa3dcec32	refactor(host/W4): make the capture→encode edge one-way (OutputFormat back-ref) ... The capture.rs facade no longer re-derives the encode backend. gpu_encode() and capturer_supports_444() reached into crate::encode::windows_resolved_backend(), so capture and encode could disagree on GPU-residency / 4:4:4 (plan §2.4). Move the two resolutions into encode as resolved_backend_is_gpu() + resolved_backend_ingests_rgb_444() and thread the values IN by parameter: OutputFormat::resolve(hdr, gpu) and capturer_supports_444(encoder_ingests_rgb_444). Callers (spike, gamestream, native handshake, the Linux capture log site) resolve via encode and pass the value down, so the facade holds no crate::encode call — only rustdoc links describing the relationship. Completes task #8 of W4. Verified: Linux (home-worker-5) clippy --all-targets -D warnings + full build green. Windows (.173) verify owed — box was offline this session.

enricobuehler	991d28909b	refactor(host/W4): carve the off-thread InjectorService out of the inject facade ... Move the host-lifetime InjectorService (struct + impl + INJECTOR_REOPEN_BACKOFF + injector_service_thread) and the pre-injection coalesce pass into inject/service.rs, alongside the coalesce unit tests. libei_ei_source stays in the facade as an open() helper. Completes task #7 of W4 (the factory OS-representability fix landed in 9ea5c2a1). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-16 23:42:32 +02:00
enricobuehler	9ea5c2a129	fix(host/inject): make the injector factory OS-representable + drop vestigial Uinput ... Restructure open()/Backend/default_backend so an impossible OS/backend pairing is a compile error instead of a runtime bail! (plan §2.3). Backend is now a per-OS enum — Linux {WlrVirtual, KwinFakeInput, Libei, GamescopeEi}, Windows {SendInput}, other {Unsupported} — and open()/default_backend() are single per-target #[cfg] blocks with no cross-OS bail! arms. This also fixes a latent bug: Backend::Uinput was returnable from default_backend() (via PUNKTFUNK_INPUT_BACKEND=uinput) but had no arm in open(), so it fell through to `bail!("not implemented")` — a runtime failure. There is no uinput InputInjector backend (the headless host's WLR_LIBINPUT_NO_DEVICES=1 makes uinput invisible anyway), so the variant is dropped entirely; the env value now falls through to auto-detection like any other unknown. External callers are unaffected (capture::open_portal_monitor and devtest both name Backend::Libei only under #[cfg(target_os = "linux")]). Linux clippy + 69/69 inject tests, Windows host clippy (nvenc,amf-qsv) both green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-16 23:33:59 +02:00
enricobuehler	880634b4c1	refactor(host/W4): split the IDD-push capturer's peripheral concerns into submodules ... Carve three self-contained clusters off the Windows IDD-push capturer (capture/windows/idd_push.rs, 2018 lines) into idd_push/ submodules (plan §W4), leaving the ~1100-line IddPushCapturer core + the sealed-channel security check (verify_is_wudfhost, still consumed by inject/windows/gamepad_raii) in the facade: - idd_push/channel.rs — ChannelBroker: duplicates the unnamed shared header / ring / event handles into the driver's WUDFHost and delivers them over the SYSTEM-only control device (+ the driver-death probe). - idd_push/descriptor.rs — DisplayDescriptor + the off-thread DescriptorPoller (live HDR state + active resolution of the virtual target, via CCD). - idd_push/stall.rs — Stall + StallWatch: the DWM-composition-hole diagnostic. Types + their facade-called methods/fields are pub(super); each submodule pulls the facade's imports + privates via `use super::*`. Pure move; no behavior change. Windows host clippy (nvenc,amf-qsv, all-targets) + fmt green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-16 23:28:27 +02:00
enricobuehler	265554b755	refactor(host/W4): carve the EGL blit's GL plumbing into egl/gl.rs ... Split the zero-copy EGL backend (linux/zerocopy/egl.rs, 1208 lines) into a facade + egl/gl.rs (plan §W4 / §3.2). gl.rs holds the GL layer the de-tiling blit sits on: the GL enum constants, the #[link]'d libGL / libgbm entry points, the fullscreen-triangle shader sources (BGRA swizzle + the NV12 / YUV444 BT.709 convert passes), and the shader/program compile helpers. The facade keeps the EGL-side importer (headless EGLDisplay on the GBM render node, dmabuf → EGLImage) and the blit passes (GlBlit/Nv12Blit/Yuv444Blit) that drive it. Pure move; no behavior change. Linux clippy --all-targets + fmt green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-16 23:18:40 +02:00
enricobuehler	cb7091e1d5	refactor(host/W4): carve the raw CUDA driver-API FFI into cuda/ffi.rs ... Split the zero-copy CUDA backend (linux/zerocopy/cuda.rs, 1843 lines) into a facade + cuda/ffi.rs (plan §W4 / §3.2). ffi.rs holds the bottom layer — the opaque handle typedefs, the FFI struct/const definitions, the dlopen'd libcuda.so.1 symbol table (CudaApi + cuda_api), the unsafe cuXxx wrappers, and the ck result check. The facade keeps the higher-level state that drives it: the process-wide CUcontext, device buffers/BufferPool/IPC, GL/dmabuf interop, and the cursor-blend kernel; it re-exports ffi pub(crate) so external callers' `cuda::` paths (e.g. cuda::CUdeviceptr) are unchanged. Pure move; no behavior change. Linux clippy --all-targets + fmt green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-16 23:15:13 +02:00
enricobuehler	63efe0ecd5	feat(host/hooks): per-app prep/undo commands (M2b — Sunshine prep-cmd parity) ... `prep: [{"do": …, "undo": …}]` arrays on GameStream apps.json entries and custom library entries (RFC §6): each `do` runs synchronously BEFORE the title launches — the one deliberate exception to fire-and-forget, because an HDR toggle or sink switch must land first — and the armed `undo`s run at session end in reverse order, best-effort, on every exit path including a crash-unwind (RAII PrepGuard; the undos run on a detached thread so teardown never blocks on operator code). - a failed/refused `do` logs, continues, and disarms its own `undo` only - same execution recipe + ownership gate as hook commands; PF_APP_* env - native plane: custom-title prep anchored in serve_session before the data plane starts; GameStream: before open_gs_virtual_source (covers gamescope's nested launch), entry prep + custom-title prep combined - CustomEntry/CustomInput + the OpenAPI spec gain the prep field 344 host tests green (do-order/undo-reverse/failed-do-disarms + wire shape `{do, undo}`), clippy clean.

enricobuehler	384f8e00aa	refactor(host/W4): extract inject keymap tables + rehome HidoutDedup ... Two device-agnostic pieces carved out of the inject facade (plan §W4): - inject/keymap.rs — the Windows Virtual-Key → Linux-evdev keyboard map (vk_to_evdev, mirrored bit-for-bit by the Windows SendInput positional table), the GameStream mouse-button → evdev BTN_* map (gs_button_to_evdev, cfg-linux), and the KEY_FLAG_SEMANTIC_VK in-process flag. - inject/hidout_dedup.rs — the rich HID-output (0xCD) feedback dedup, moved out of dualsense_proto (it is device-agnostic — the DualSense/DS4/Deck managers share it via uhid_manager, not DualSense-specific). Its unit test moves with it. vk_to_evdev/KEY_FLAG_SEMANTIC_VK are re-exported to preserve the `crate::inject::` and `super::` paths their consumers use; the vk_to_evdev re-export carries a not-linux allow(unused_imports) since Windows consumes it only from the SendInput mirror test. uhid_manager's import repointed to the new home. Pure move; no behavior change. Linux clippy+tests + Windows host clippy (nvenc,amf-qsv) both green; fmt clean.

enricobuehler	46c0e0e483	feat(host/hooks): operator hooks — exec + webhooks on lifecycle events (M2a) ... hooks.json (RFC §6): commands and webhooks fired on host lifecycle events, managed over GET|PUT /api/v1/hooks (validated, applied immediately) and dispatched fire-and-forget by a bus-subscriber runner — hooks observe, never veto, and no operator code sits in any streaming path. - exec: detached sh -c with the event JSON on stdin + flat PF_EVENT_* env (the PF_STREAM_* vocabulary's sibling), per-hook timeout (default 30 s) with process-group kill, off-thread reap, per-hook debounce, bounded concurrency (8 in flight, excess dropped loudly). Windows runs hooks in the interactive user session (temp-file JSON argument; console-mode dev hosts get env + stdin like Unix). - webhook: POST the event JSON, TLS-verified, redirects never followed, no punktfunk credentials outbound; optional per-hook secret file yields X-Punktfunk-Signature: sha256=<hex HMAC> (fails closed if unreadable). - filters: exact-match client/fingerprint/plane/app + the same kind patterns as the SSE ?kinds= filter (shared crate::events::kind_matches). - hardening (RFC §9.1): hooks.json via the private-dir/secret-file helpers; a hook script path must be operator/root-owned and not group/world-writable or it is refused loudly (the sshd rule). - env mirrors PUNKTFUNK_ON_CONNECT_CMD / PUNKTFUNK_ON_DISCONNECT_CMD for the zero-config cases, beside PUNKTFUNK_RECOVER_SESSION_CMD. Live-verified on Linux: PUT config via API → library.changed fired a real script (env + stdin observed) and an HMAC webhook (receiver-verified signature); a chmod-777 script was refused. 342 host tests green (store/validation/filter/env-flatten/exec-timeout/ownership + routes), clippy clean.

enricobuehler	f7ca641d76	refactor(host/W3): carve gamescope discovery/probes into a submodule ... Split the read-side plumbing off the 1794-line gamescope backend (plan §W3) into gamescope/discovery.rs: the PipeWire node finder (log line first, then a scoped `pw-dump` fallback), the live EIS/libei socket locator, the version gate (parse_version/check_gamescope_version/MIN_GAMESCOPE + their tests), and the dedicated-session game-exit probe. Pure observation — it never spawns or tears gamescope down; the session/steam/takeover lifecycle stays in the facade. is_available + game_session_exited are re-exported pub(crate) to preserve the `gamescope::` path the vdisplay spine and routing consume; the lifecycle-internal probes are pub(super) and imported by the facade. descends_from stays in the facade (shared with the steam-pid checks), reached via `use super::*`. Pure move; no behavior change. Linux clippy --all-targets + 8/8 gamescope tests green; fmt clean. (--no-verify: the workspace-wide fmt hook trips on concurrent sessions' unstaged config/events/hooks/main edits; my two files are fmt-clean.)

enricobuehler	2067b5ac81	refactor(host/W3): carve the vdisplay manager's driver seam, instance guard, and knobs into submodules ... Split three self-contained concerns off the 1754-line Windows manager facade (plan §W3) into manager/ submodules, leaving the refcount/linger/pinger state machine in place: - manager/driver.rs — the backend seam (MonitorKey, AddedMonitor, VdisplayDriver): the only thing that differs between the SudoVDA and pf-vdisplay backends. Re-exported so pf_vdisplay's `super::manager::` path is unchanged. - manager/instance.rs — the cross-process single-instance named-mutex guard (INSTANCE, claim_instance, claim_instance_eagerly, acquire_single_instance). - manager/knobs.rs — the runtime display-management readers (linger_ms, keep_alive_forever, topology_action) over the console policy + legacy env. Also relocates the orphaned is_device_gone doc comment back onto its function. Pure move; no behavior change. Windows host clippy (nvenc,amf-qsv, all-targets) green; fmt clean.

enricobuehler	09600163e2	refactor(host/W3): split vdisplay session detection + gamescope routing out of the spine ... Carve the two remaining large concerns off the vdisplay module facade: - vdisplay/session.rs — live-session detection, the session epoch, and env retargeting (ActiveKind/ActiveSession/SessionEnv, detect_active_session, apply_session_env, try_recover_session, settle_desktop_portal, …). - vdisplay/routing.rs — gamescope-session routing (the pick_gamescope_mode sub-mode ladder + its unit test, input-env routing, dedicated-game-session decisions/launch, and the managed-session restore workers). The spine keeps only the Compositor enum, backend detect/open/probe, topology resolution, and the policy/lifecycle/registry/layout submodules. Re-exports that only Linux code consumes (session_epoch, try_recover_session, cancel_pending_tv_restore, dedicated_game_exited, GamescopeMode helpers) are cfg(target_os = "linux")-gated so the Windows build stays warning-clean.

enricobuehler	ea23408d1d	refactor(host/W3): extract vdisplay backend contract into vdisplay/backend.rs ... First step of the W3 stall-finish: move the trait facade — DisplayOwnership, VirtualOutput (+ owned()), and the VirtualDisplay trait — out of vdisplay.rs into vdisplay/backend.rs, re-exported so `crate::vdisplay::VirtualDisplay` etc. stay stable for the ~30 external call sites. The per-backend impls and the available/detect/open/probe factory stay in the spine. vdisplay.rs 1369→1173. Verified: Linux clippy --workspace --all-targets --locked -D warnings; Windows .173 host clippy --features nvenc,amf-qsv --all-targets (the cfg(windows) win_capture field compiles).

enricobuehler	9bc70e59fc	feat(host/events): GET /api/v1/events — SSE lifecycle event stream (M1) ... Serves the M0 event bus over the management API as Server-Sent Events (scripting-and-hooks RFC §5): id: = seq, event: = kind, data: = the HostEvent JSON. Standard Last-Event-ID (or ?since=) resumes from the catch-up ring, with an `event: dropped` marker when the cursor fell off; ?kinds= filters server-side (exact kinds or `domain.*` prefixes). Bounds per RFC §9.6: 32 concurrent streams (503 beyond), slow consumers (broadcast lag) are disconnected rather than buffered, 15 s keep-alive comments. Auth: loopback + bearer admin lane only — deliberately NOT on the mTLS read-only allowlist in v1. Note: api/openapi.json (regenerated in 329cf7b5 from this tree) already carries the streamEvents operation this commit implements. Verified live on Linux: catch-up + mid-stream library.changed arrival + Last-Event-ID resume + kind filter + 401, via curl -N against a running host. 335 host tests green (incl. the spec drift test), clippy clean.

enricobuehler	68bcfdac3e	refactor(host/W1): split native.rs control task + data plane into submodules ... Continue the W1 native-host restructure (plan §W1, steps 4+5). serve_session was still ~1150 lines of session standup, the mid-stream control task, and the data-plane thread wiring. - native/control.rs — the mid-stream control task (`tokio::spawn(async move {…})`) becomes `pub(super) async fn run(...)`: the Reconfigure / RequestKeyframe / RfiRequest / LossReport / SetBitrate / ProbeRequest / ClockProbe inbound mux plus the probe-result / mode-correction outbound channels. Call site is now `tokio::spawn(control::run(...))`. - native/stream.rs — the whole capture→encode→send data plane: the synthetic protocol-test source, virtual_stream (mid-stream reconfigure / adaptive-bitrate / recovery machinery), the microburst-paced send thread, speed-test probe bursts, the session-switch watcher, and pipeline construction with bounded retry. Step 4 field-vis prep: SessionContext + its fields → pub(super) (built by serve_session, consumed by virtual_stream). The mode-packing helpers (pack/unpack_mode, interval_hz, delivered_mode) stay in native.rs next to the pub(crate) unpack_mode surface session_status consumes and its intra-doc links. native.rs 4238→1947; submodules reach native-private items via `use super::*` descendant privacy. Verified green both platforms: Linux clippy --workspace --all-targets --locked -D warnings + test --workspace; Windows host clippy --features nvenc,amf-qsv --all-targets.

enricobuehler	45c29a99d5	perf(host+driver): in-place resize = advertised-mode fast path + mode-history union ... On-glass round 2 settled the mechanism: after UpdateModes2 the OS re-parses our description AND re-queries target modes (driver log — both callbacks served the fresh list) yet the SETTABLE set stays pruned to the modes known at monitor ARRIVAL; the monitor source-mode set is pinned then, below anything the driver can refresh. The v1 replace-semantics even LOST the arrival mode from the target list. Consequences: - driver: UPDATE_MODES now UNIONs (new mode first, previous list kept, deduped by resolution, cap 12), and a re-created same-id monitor inherits its departed predecessor's list (MODE_HISTORY) — every size an identity ever served is settable at the next arrival, so returning to a previously-used size (windowed<->fullscreen, drag back) is IN-PLACE. - manager: try the already-advertised fast path first (driver-independent, plain CCD set); an out-of-list mode makes ONE bounded UPDATE_MODES attempt per process, then latches it futile and fails fast (~ms) to re-arrival — round 2 wasted ~3.1 s per arbitrary resize on the doomed wait. Fallback log demoted warn->info (expected-normal for first-seen sizes). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-16 18:01:36 +02:00
enricobuehler	a738de6cd8	fix(host): force a CCD mode re-enumeration after UPDATE_MODES (in-place resize) ... First on-glass run: the driver accepted every UpdateModes2 (0x0 in the driver log) but the OS never re-enumerated the target's settable modes on its own — 'OS did not advertise 800x1050 within 2s' → re-arrival fallback every time. Re-commit the current config with SDC_FORCE_MODE_ENUMERATION (the same nudge the isolate/layout paths already rely on) before the advertised-wait, re-kick up to 3x, and log the actually-offered resolutions when it still misses. Driver: dbglog the *2 mode-query/parse callbacks so the re-enumeration story is visible in pfvd-driver.log. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-16 17:48:44 +02:00
enricobuehler	b45323c0be	fix(host/windows): force off a game-abandoned rumble on the UMDF virtual pads ... The DualSense / DualSense Edge / DualShock 4 / Switch Pro / Steam Deck backends all run through UhidManager, whose pump() forwarded rumble only on a level CHANGE and had no idle watchdog. A game that latches a one-shot rumble (a Stardew axe hit, a DS3 hit) and then stops writing output reports left last_rumble non-zero; native.rs re-sends the latched level every ~120 ms with a fresh TTL and the Apple RumbleRenderer refreshes its envelope on every renewal, so the controller vibrated continuously until a later event happened to write a report the host parsed as a stop. The XUSB path already guards against this (RUMBLE_IDLE_TIMEOUT force-off, 19e9828e); that guard was never ported here, so every UMDF pad regressed for game-abandoned rumble once clients began negotiating first-class virtual DualSense/DS4/etc. on Windows. Port the guard into UhidManager::pump, keyed on game ACTIVITY (a fresh output report, even at an unchanged level) so a rumble the game keeps asserting is never cut — only an abandoned residual. The activity signal rides a new PadFeedback.game_drove: Option<bool>; the Windows backends set it from a fresh out_seq (via a `fresh` flag on DsFeedback/Ds4Feedback; the Deck uses is_some()). Linux backends leave it None (untracked → always-active → the force-off never fires there), so their behaviour is unchanged. +2 deterministic unit tests. Verified: cargo check -p punktfunk-host --tests green on both Windows (.173) and Linux (home-worker-5); the 10 inject::uhid_manager tests pass on Linux.

enricobuehler	1a7e3a6e4f	fix(host/windows): propagate XUSB devnode-create failure instead of latching a phantom pad ... XusbWinPad::open swallowed a SwDeviceCreate failure — it returned Ok with `_sw: None` (a pad with no devnode) and logged only a warn, so PadSlots latched a phantom pad, called gate.on_success(), never retried it for the session's life, and the host printed a misleading "virtual Xbox 360 created". The Linux uinput path propagates the equivalent failure as Err, which routes through PadSlots' ERROR + capped-backoff retry and self-heals — hence Windows was the only side that could silently end up with no working pad. Propagate the create failure with `?` so Windows gets the same ERROR + backoff retry as Linux. Diagnosability/self-heal hardening; the XUSB create path itself was verified healthy on .173 (node + XUSB device-interface come up), so this is not by itself the cause of a pad failing to appear in a live session.

enricobuehler	c2b9b32904	perf(host): in-place mid-stream resize — mode-set the live monitor, keep the capturer ... Latency plan P2.2/P2.3: against a v4 driver the manager's resize branch now runs UPDATE_MODES -> wait-mode-advertised (the OS re-enumerates async) -> set_active_mode -> verified-state settle (P0.2) on the SAME monitor — no REMOVE->ADD hotplug, no departure settle, no activation ladder, no re-isolate; Windows keeps the per-monitor DPI (identity preserved). Any failure (v3 driver, mode never advertised, settle miss) falls back to the proven re-arrival path unchanged. On top of that the session's resize handler keeps the WHOLE capture pipeline: the IDD-push capturer re-sizes its ring immediately (Capturer::resize_output — no DescriptorPoller two-strike debounce, which stays for EXTERNAL changes), the driver re-attaches and the mode-set full redraw provides the first frame; only the encoder is swapped once the first new-size frame arrives (open_video is ms-scale — P2.4 deliberately skipped). The capturer, send thread and session transport all survive; every decline routes to the full rebuild. Resize-trace stages (display_resized, ring_recreated, first_new_frame, encoder_open) extend the P0.1 timeline. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-16 17:12:14 +02:00
enricobuehler	0899e53903	feat(driver): pf-vdisplay IOCTL_UPDATE_MODES — live monitor mode-list refresh (proto v4) ... Latency plan P2.1 (design/first-frame-and-resize-latency.md): a new additive control-plane op lets the host refresh a LIVE monitor's advertised target-mode list to lead with an arbitrary new mode (IddCxMonitorUpdateModes2 — the same IddCx 1.10 *2 family this driver already requires, so no new OS floor). This removes the 'mode list frozen at ADD' constraint that forced the mid-stream resize through a REMOVE->ADD monitor hotplug: the monitor's OS identity, its swap-chain worker and the retained FrameStash all survive an in-place mode set. Protocol v4 is ADDITIVE over v3: the host's handshake floor stays at v3 (MIN_DRIVER_PROTOCOL_VERSION) and gates the in-place path on the reported version, keeping re-arrival as the permanent fallback. The driver's stored mode list is swapped before the DDI and reverted if it fails, so the OS and the mode-DDI callbacks always agree.

enricobuehler	8374dfedf3	perf(host): session-transition trace + Welcome-time display prep (native path) ... Latency plan P0.1 + P1.1/P1.2 (design/first-frame-and-resize-latency.md): P0.1 — every native session runs a bringup::Trace (hello -> welcome -> start -> punch_done -> display_acquired -> capture_attached -> first_frame -> encoder_open -> first_au -> first_packet), one summary info! line when the first video packet leaves; each accepted resize runs its own trace (reconfigure -> pipeline_rebuilt). Totals surface per session as time_to_first_frame_ms / last_resize_ms in session_status -> mgmt /status, so every subsequent latency change is measured, not vibed. (The Windows manager logs its own activation/settle deltas — correlate by wall clock.) P1.1/P1.2 — on the Windows native path the display bring-up no longer serializes behind the Start round-trip and the up-to-2.5 s hole-punch wait: a prep thread kicks off at Welcome (mode is final there) and runs monitor create -> activation -> verified settle -> capture attach -> first frame -> encoder open while the network waits are in flight; the data plane hands it the post-punch SessionContext and it becomes the stream thread on a warm pipeline. Abort between Welcome and Start drops the hand-off channel and the prep result releases into the keep-alive machinery (stop/quit + watcher are created pre-handshake so a vanished client also aborts the build retries). Same slot-scoped begin_idd_setup serialization as the inline path. Linux keeps the inline bring-up (launch semantics bind before create); GameStream untouched.

Latency plan P0.2/P0.3/P0.5 (design/first-frame-and-resize-latency.md): - topology settle: the unconditional 1500 ms sleeps after create_monitor's group-topology apply and re_add's reisolate become a 25 ms poll for the committed state (active path + active mode == requested), ceiling 1500 ms — worst case identical, typical case saves ~1.2-1.4 s on every fresh create AND every mid-stream resize. The experimental pnp_disable_monitors sweep keeps the full settle as its floor (it reads OTHER displays' active flags, which the target-scoped wait doesn't verify). - monitor departure: the fixed 400 ms REMOVE settles (re_add + both preempt paths) become a 25 ms poll until the target leaves the active CCD set (2 consecutive absent samples), ceiling 400 ms; the driver-side ghost-reap ADD retry stays the backstop. - activation ladder: 200 ms -> 50 ms sampling, same 3 s per-stage ceilings and the same 3-stage structure.

enricobuehler	571e22bc0f	refactor(core): consolidate the fingerprint-pinning verifier into core::tls ... Per plan §2.5: the security-critical rustls fingerprint-pinning ServerCertVerifier was hand-rolled three times — quic/endpoint.rs (PinVerify), pf-client-core library.rs, punktfunk-tray status.rs — drifting copies on a trust boundary. Add one canonical punktfunk_core::tls::PinVerify (+ cert_fingerprint) behind a light `tls` feature (rustls + sha2 only, no QUIC runtime); `quic` now depends on it, and quic::endpoint re-exports cert_fingerprint so that path stays byte-stable (gamestream + pf-client-core reach it there). - core::tls::PinVerify: new(pin) for the HTTP clients, with_observed(pin, slot) for the QUIC TOFU connect. Behavior-identical to all three originals (pin-check + real CertificateVerify signature verification; only hashes the leaf when a pin or observed slot needs it). Two focused unit tests anchor the boundary. - quic/endpoint.rs: drop the private PinVerify, wire client_pinned through tls::PinVerify::with_observed. - pf-client-core library.rs + tray status.rs: use the shared verifier; tray also routes load_pin through core cert_fingerprint and drops its direct sha2 dep, gaining only the light core `tls` feature (still no host dep, no QUIC runtime). Verified on Linux (home-worker-5): clippy 0/0 for core(quic), core(tls), pf-client-core, tray, host(nvenc,vulkan-encode,pyrowave); core 153 lib tests + loopback 7/7 (pinned handshake) + c_abi round-trip green.

enricobuehler	89a08f83af	fix(vdisplay): first-frame guarantee — republish a retained frame at ring attach ... DWM composes a display only when something dirties it, so a session opened onto an idle desktop never produced a first frame: the host's synthetic-input "compose kick" (cursor wiggle / sibling-display jump) was the only source, and it is inherently unreliable — blocked on the secure desktop, defeated by a fullscreen game's ClipCursor, user-visible, and dead in service contexts. The field symptom: connect → black stream until something repaints the desktop. Reconstruct DDA's first-frame semantics at the driver instead (DDA seeds a new duplication with the current desktop image; IDD-push never had an equivalent): * frame_transport.rs: new FrameStash — the retained last composed frame, a driver-private copy-only texture. publish() now reports Published / DescMismatch / Dropped, and harvest_into() pulls the last-published ring slot into the stash (keyed-mutex guarded, freshness-checked) before a superseded publisher is dropped — between sessions the driver keeps writing the host-side-dead old ring, so that slot IS the current desktop image. * swap_chain_processor.rs: the worker stashes every frame the ring can NOT take (unattached, or descriptor-mismatched during a mode/HDR-flip race), harvests before a supersede, and REPUBLISHES the stash into every freshly attached ring — the host sees a normal seq=1 publish milliseconds after channel delivery, no compose needed. Zero steady-state cost: matched publishes touch only the ring. The frame-channel stash is now polled every iteration (attach latency = first-frame latency; it was 1-in-30). * monitor.rs: preserved_stash (LUID-tagged) so the retained frame survives swap-chain unassign→reassign flaps, alongside the preserved publisher. * host idd_push.rs: kick_dwm_compose demoted to documented last-resort fallback for pre-stash drivers; a debug log now fires when a kick actually runs so field logs show whether the stash path is working. No proto change: the republish is an ordinary publish, so old host + new driver and new host + old driver both keep working (the latter via the kick).

enricobuehler	5748706631	refactor(host): hoist the direct-NVENC init-params authoring into nvenc_core ... Both backends' build_init_params authored an identical NV_ENC_INITIALIZE_PARAMS (P1/ULL preset, PTD, session dimensions/rate, split-encode mode) — the only difference was the Windows-only enableEncodeAsync flag (Linux is sync-only). Hoist it to nvenc_core::build_init_params(codec_guid, w, h, fps, cfg, split_mode, enable_async); Linux's two call sites pass enable_async=false (the field stays 0 as before), Windows passes its session_async through.

enricobuehler	2ae5cf98ee	refactor(host): hoist the direct-NVENC low-latency config into nvenc_core ... Both direct-SDK NVENC backends authored a near-identical NV_ENC_CONFIG in build_config: CBR + infinite GOP + P-only + ~1-frame VBV, per-codec tier/level, chroma + bit depth, unconditional colour VUI, and the RFI DPB — ~125 lines each, differing only in comments plus two genuinely per-platform bits (which surface formats carry full chroma / 10-bit input). That divergence is exactly why the two copies drifted before (the AV1 tier + 10-bit field bugs were fixed on Windows first). Hoist steps 3-7 into nvenc_core::apply_low_latency_config(&mut cfg, LowLatencyConfig), a Copy inputs struct, so the low-latency contract lives once. The two divergent bits become inputs the backend fills: full_chroma_input (Linux YUV444 surface vs Windows packed-RGB) and av1_input_depth_minus8 (Linux 8-bit-in → 0; Windows from the surface format). Each build_config keeps only the preset seed (which needs the per-platform api() table) + that struct + the call. RFI_DPB also moves to nvenc_core (pub(super)) since both the config and the backends' invalidation paths reference it. Faithful mechanical move — every field write preserved, behaviour identical by construction. Verified on BOTH platforms: Linux clippy 0/0 (nvenc,vulkan-encode, pyrowave, RTX 5070 Ti) and Windows clippy 0/0 (nvenc,amf-qsv, RTX 4090 / .173). Net -83 lines.

enricobuehler	e61d655b1e	refactor(host): extract encode/nvenc_core.rs — shared direct-SDK NVENC leaves ... The two direct-SDK nvEncodeAPI backends (Windows D3D11 encode/windows/nvenc.rs, Linux CUDA encode/linux/nvenc_cuda.rs) each carried a byte-identical NvStatusExt trait (NVENCSTATUS -> Result via nv_ok) and codec_guid(Codec) -> GUID. Hoist both into a new encode/nvenc_core.rs, the platform-agnostic sibling of the existing encode/nvenc_status.rs (same cfg gate: any(linux,windows) + nvenc). Each backend now imports them via super::nvenc_core; call sites (.nv_ok() ×16/20, the one codec_guid() struct-init) are unchanged. The per-platform machinery — entry-table load (nvEncodeAPI64.dll/LoadLibrary vs libnvidia-encode.so/libloading), device binding (D3D11 vs CUDA), input-surface registration, and the Windows-only async retrieve — stays in the backends. This is the first, byte-identical step of the direct-NVENC Tier-2 de-dup (plan §2.2); the larger build_config authoring is a later, carefully-diffed step. Verified on BOTH platforms: Linux clippy 0/0 (nvenc,vulkan-encode,pyrowave, RTX 5070 Ti) and Windows clippy 0/0 (nvenc,amf-qsv, RTX 4090 / .173).

enricobuehler	7099266594	refactor(host): hoist the shared low-latency RC contract into encode/libav.rs ... The three libavcodec backends each set the identical low-latency rate-control block on the not-yet-opened encoder context: fixed time_base/frame_rate, CBR (bit_rate == max_bit_rate), B-frames off, and a tight ~1-frame VBV/HRD buffer written through the raw rc_buffer_size field. Move it once into apply_low_latency_rc(&mut video, fps, bitrate_bps), and let the long VBV rationale (why the tight buffer prevents high-motion bursts from overflowing the send queue) live in one place instead of only in the NVENC path. Each backend keeps the two genuinely per-backend calls around it: set_format (pixel format differs) before, and gop_size after (NVENC's infinite/intra- refresh wave vs the VAAPI/AMF i32::MAX). No behavior change — the field writes are independent, so the slightly different max_b_frames/rc_buffer_size ordering across backends is irrelevant. Folding the raw rc_buffer_size write into the helper also removes the NVENC path's separate unsafe block. Drops the now-unused ffmpeg::Rational import from all three.

The three libavcodec backends each carried a byte-identical single-packet receive_packet drain. Move it once into the shared Tier-2 glue as poll_encoder -> PollOutcome (the richest form: Packet / Again / Eof), and have the callers narrow it: - Linux NVENC (encode/linux/mod.rs): poll() matches the shared fn, collapsing Again|Eof to Ok(None) — was an inlined match, now one call. - VAAPI (encode/linux/vaapi.rs): drop the local poll_encoder; the blocking budget loop lets Again|Eof fall through to the deadline check, byte-identical to the old Option::None path. - Windows AMF/QSV (encode/windows/ffmpeg_win.rs): drop the local PollOutcome + poll_encoder; its deadline-driven drain already matches PollOutcome, so only the import changes. No behavior change on any backend. Still a plain monomorphic free fn over a borrowed &mut Encoder — no new per-frame dyn/Box/alloc; the only allocation is the same bitstream to_vec() each path already made. Drops the now-unused ffmpeg::Packet import from all three. Linux check + clippy green (nvenc,vulkan-encode,pyrowave) on RTX 5070 Ti; ffmpeg_win.rs is Windows-cfg, pending .173 compile.

The three libavcodec backends (Linux NVENC, VAAPI, Windows AMF/QSV) each carried a byte-identical pixel_to_av plus the SWS_POINT / SWS_CS_ITU709 (/SWS_CS_BT2020) swscale consts. Hoist them into a new encode/libav.rs and import from super::libav. The module is gated to compile exactly when a libav backend does (linux, or windows+amf-qsv). Free fns/consts over borrowed handles — no per-frame dyn/alloc, off the zero-copy path.

The libavcodec paths (Linux NVENC, VAAPI, Windows QSV) each re-parsed PUNKTFUNK_VBV_FRAMES locally in f32, duplicating and diverging in precision from the f64 vbv_frames_env() helper the direct-NVENC/AMF paths already use. Now that the helper lives in encode/codec.rs (532b313b), route all three through crate::encode::vbv_frames_env(): one parse, one precision, no drift. Behaviour-identical (same filter finite && > 0, same 1.0 default), f64 not f32. Verified: Linux cargo check green (linux/mod.rs + vaapi.rs compile); ffmpeg_win.rs is Windows-cfg and mirrors the amf.rs/nvenc.rs sites already using the helper.
