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. On-glass with a real client session owed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-16 22:02:35 +02:00
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. Pure move; no behavior change. Linux clippy+tests and Windows host clippy (nvenc,amf-qsv) both green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-16 21:27:18 +02:00
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	393b47a062	fix(tray): allow has_conflicts on non-Linux (Windows -D warnings dead-code) ... has_conflicts drives the Linux ksni backend's NeedsAttention state; the Windows tray surfaces the same conflict through the tooltip headline() (it has no distinct attention icon) and never calls the boolean, so `cargo clippy -p punktfunk-tray -- -D warnings` failed dead-code on Windows (windows-host.yml). Scope the allow to non-Linux rather than gate the shared API out. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-16 20:45:22 +02:00
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	ecfa71212d	chore: consolidate all in-progress parallel-session WIP ... Wholesale commit of every uncommitted change across the tree, at the user's explicit request — host refactor-campaign W1 (native.rs facade + native/ dir, library/ + mgmt/ splits), Android, core. These streams were mid-flight and not individually built/tested together; this supersedes the per-session HOLD markers. Consolidating so everything lands on main in one pass.

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	4ffa2665ac	refactor(host): extract src/devtest.rs — the standalone dev/test subcommands ... Per plan §W5 (main-cli, 'devtest.rs land first'): move the inline-bodied dev/test subcommand handlers out of main.rs's match into src/devtest.rs — input_test (Linux libei/wlr injection smoke test + its non-Linux stub) and the virtual-gamepad exercisers dualsense_test/switchpro_test (Linux UHID) and deck_windows_spike/ dualsense_windows_test (Windows UMDF + Steam Deck devnode spike). main.rs's arms become one-line forwards; main.rs drops 1004→667 lines. The thin arms that already forward to subsystem modules (zerocopy/capture selftests, probes) stay put — that is their correct layer. Pure code-move (bodies verbatim; crate-local refs qualified with crate::; one doc reword to dodge clippy doc_lazy_continuation now that an arm comment became a /// doc). Verified clippy 0/0 on BOTH Linux (home-worker-5, nvenc,vulkan-encode,pyrowave) and Windows (.173, nvenc,amf-qsv — covers the cfg(windows) handlers).

enricobuehler	2def3ef49e	refactor(host): extract native_pairing/sanitize.rs — the untrusted-name scrubber ... Per plan §W5: move sanitize_device_name (+ its NAME_MAX cap and unit test) out of the native_pairing facade into native_pairing/sanitize.rs. It is a self-contained, security-relevant leaf — the one place a wire-supplied unpaired-device name is scrubbed of control chars / bidi-override spoofing before it is stored, listed, logged, or shown in the approval UI. Re-export via `pub(crate) use` so crate::native_pairing::sanitize_device_name stays stable (punktfunk1 accept loop + the two in-crate callers). Pure code-move; verified host clippy 0/0 + 11 native_pairing tests green on Linux (home-worker-5). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-16 15:42:55 +02:00
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	405b005a0d	refactor(host): extract audio/mic_pump.rs — the host-lifetime virtual-mic pump ... Per plan §2.1: a self-contained stateful subsystem does not belong in the audio trait facade. Move MicPump + its PumpTuning/PUMP_TUNING, the drain_sleep/pump_thread loop, MIC_CHANNELS/MIC_QUEUE_CAP, and the six pump unit tests out of audio.rs into audio/mic_pump.rs. audio.rs keeps the AudioCapturer/VirtualMic traits, their open_* factories, and the sample constants. Re-export via `pub use mic_pump::MicPump` so crate::audio::MicPump stays byte-stable (only consumer: punktfunk1.rs). Pure code-move; verified clippy 0/0 + 6/6 pump tests green on Linux (home-worker-5). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-16 15:21:36 +02:00
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. Keeps open and in-place reconfigure presenting the SAME init params, now guaranteed identical across platforms too. 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	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. Linux check + clippy green (0/0, nvenc,vulkan-encode,pyrowave) on RTX 5070 Ti; ffmpeg_win.rs is Windows-cfg, pending .173 compile.

enricobuehler	fd8a062e2c	refactor(host): hoist the libav poll_encoder drain + PollOutcome into encode/libav.rs ... 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.

enricobuehler	3c38a5f0e8	refactor(host): hoist shared libav glue into encode/libav.rs (pixel_to_av + swscale consts) ... First step of the W2 libav de-dup (plan §2.2, the missing Tier-2 mid-layer). 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. Verified: Linux cargo check green (linux/mod.rs + vaapi.rs compile against it); ffmpeg_win.rs is Windows-cfg — same mechanical swap, covered by Windows CI on push.

enricobuehler	abecb5226c	refactor(host): route the three libav backends' VBV re-parse through vbv_frames_env ... 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.

Local snapshot of intermingled in-flight work, committed to unblock the encode refactor (a clean ffmpeg_win.rs for the vbv-dedup follow-on). These hunks span the same files and can't be cleanly split here; the commit bundles three distinct workstreams that each belong in their own PR: - logging rework (~43 files: level re-tiering, structured fields, `?e`, hot-path flood latches) - conflicting-host detection (detect.rs + detect/{linux,windows}.rs + wiring in main.rs/mgmt.rs/Cargo.toml/docs/packaging) - standby-sink DWM-stall attribution (windows/display_events.rs + capture/ vdisplay wiring) NOT verified as a combination. NOT to be pushed until the refactor is done and these are re-verified and reorganized into their proper per-workstream PRs.

enricobuehler	532b313b8c	refactor(host): extract encode/codec.rs — the encoder contract ... Move the Tier-1 encoder contract out of the stuffed encode.rs facade into a new encode/codec.rs submodule (plan §7 / W2): EncodedFrame, Codec (all methods except host_wire_caps), ChromaFormat, EncoderCaps, the Encoder trait, validate_dimensions, vbv_frames_env, and the dimension + wire-roundtrip contract tests. host_wire_caps stays in encode.rs alongside the backend-selection probes it depends on; CodecSupport and its wire-mask test stay too. encode.rs gains `mod codec;` + `pub(crate) use codec::*;` so every existing crate::encode::X path — crate::encode::vbv_frames_env, ::Codec, ::Encoder, … — stays byte-stable. Pure relocation: no call sites touched. Verified: dev-Mac type-check of both files clean; Linux `cargo check -p punktfunk-host --features nvenc,vulkan-encode,pyrowave` green (all encode backends compile against the relocated contract); contract unit tests pass.

enricobuehler	d381cdf7f4	fix(host): NVENC open-failure resilience — backoff, failed-open hygiene, self-diagnosis ... Field report (Linux direct NVENC): after a codec switch, every session open failed with NV_ENC_ERR_INVALID_VERSION until the host process was restarted — so the poisoned state is per-process, not a driver install issue. On-hardware investigation (RTX 5070 Ti, 610.43.03) could not reproduce it with clean codec cycles, dirty teardowns, or open/destroy storms, but established the failure class: the driver enforces a per-process concurrent-session cap (12 there, status INCOMPATIBLE_CLIENT_KEY; other branches report differently) whose exhaustion is exactly this signature — persistent open failures healed only by a process restart. Harden every path that can feed or mask that state: * Rebuild backoff: the in-place encoder-rebuild retries slept one frame interval, so all 5 attempts burned within ~40 ms at 120 Hz — no driver-side transient (deferred teardown of the previous session, engine reset) can clear that fast. Exponential backoff 100 ms → 1.6 s (~3 s total) so transients heal instead of killing the session. * Destroy-on-failed-open (Linux + Windows, all four open sites): the NVENC docs require NvEncDestroyEncoder even when OpenEncodeSessionEx FAILS — the driver may have allocated the session slot before erroring. Without it a retry burst against a transient leaks slots toward the cap, converting the transient into permanent exhaustion. * Teardown: a destroy_encoder failure (a session slot the driver may keep) is now logged with its status instead of silently discarded. * One-shot self-diagnosis on a failed session open (Linux): retry the raw open on a fresh dedicated CUDA context and log which of the three causes applies — shared-context poisoned (fresh works), driver-level skew/exhaustion/GPU loss (fresh fails the same way), or CUDA itself unhealthy (no fresh context) — so the next field report pinpoints the root cause with zero reporter effort. On-hardware regression tests (RTX box .21, all green): codec-switch reopen cycle (H265→AV1→H265→H264→H265), dirty teardown with in-flight encodes, and the full open-failure→diagnosis→in-place-recovery path via real session-cap exhaustion. Existing RFI/reconfigure/4:4:4 smokes still pass; clippy clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-16 01:57:36 +02:00
enricobuehler	f901bedf22	fix(host): actionable NVENC error logging — drop misleading "(no NVIDIA GPU?)" ... Every NVENC entry-point failure was annotated "(no NVIDIA GPU?)", which misled triage: the direct-NVENC path only loads on a machine that HAS an NVIDIA GPU. A Linux user hit NV_ENC_ERR_INVALID_VERSION at open_encode_session_ex (past the NvEncodeAPIGetMaxSupportedVersion pre-flight gate) — the signature of a userspace/kernel driver version skew that a host reboot fixes — and the log pointed at a missing GPU instead. A restart did fix it. Add encode/nvenc_status.rs: a shared NVENCSTATUS -> cause mapper that folds the real cause into the anyhow::Error at construction, so every downstream {e:#} log (the encode-recovery loop, session teardown) improves for free. INVALID_VERSION now reads "update the NVIDIA driver, or reboot if you just updated it (a host restart is the usual fix)"; NO_ENCODE_DEVICE / DEVICE_NOT_EXIST / INCOMPATIBLE_CLIENT_KEY (session-count limit) / OOM / UNSUPPORTED_PARAM get their own glosses. The required API version comes from the SDK consts so it stays correct across crate bumps. Wire it into all NVENC entry-point failures in both backends (encode/linux/nvenc_cuda.rs, encode/windows/nvenc.rs) — every open, init, preset/resource/bitstream call. Also: when the encode-recovery loop exhausts its in-place rebuilds it now logs a clear terminal line with the underlying cause instead of the session silently vanishing after the last identical "rebuilt in place" line.

enricobuehler	ac60db5410	fix(host): make the stream-marker lifecycle test parallel-safe ... marker_appears_while_held_and_vanishes_after drove the PROCESS-GLOBAL registry and mutated XDG_RUNTIME_DIR mid-run — the punktfunk1 integration tests announce real sessions concurrently in the same test process, so whichever registered first became the primary and the marker carried its mode instead of the test's 2560x1440 (flaky on CI, green locally by timing). The registry gains insert/remove methods and rewrite() takes the target path, so the test now exercises the same end-to-end lifecycle (atomic write, primary retention, session count, removal) against a LOCAL registry and an explicit temp path — no env mutation, no shared state. Production behavior unchanged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 21:32:09 +02:00
enricobuehler	6b9f261dff	style(host): rustfmt sweep for the console-sweep push ... b8da32e8 landed with two call sites and a log line rustfmt rewraps; CI's cargo fmt --all --check gate was failing on every run since.

enricobuehler	b8da32e8b6	fix(host): native sessions on the console + GPU-aware codecs + gamestream capability ... The web console Dashboard read AppState.{streaming,launch,stream}, which only the GameStream path writes, so a native punktfunk/1 session (the DEFAULT plane) showed "Idle / no session" while actively streaming — only the Stats page (shared recorder) reflected it. Add a plane-neutral per-session registry (session_status.rs) the native video loop publishes to; /status now merges both planes, reports active_sessions, and the Stop / Request-IDR buttons reach native sessions too (so surfacing them doesn't leave dead buttons). LocalSummary (tray) gets the same fix. Also on the management API: - /host codecs derive from Codec::host_wire_caps() instead of a hardcoded [H264,H265,AV1], so codecs the GPU can't encode no longer appear. - ApiCodec serializes HEVC as "hevc" (matching the wire/SDP/stats label) so the same codec reads identically across console pages. - HostInfo.gamestream reports whether the GameStream planes run (--gamestream), so the console can hide the Moonlight-only pairing UI on the native-only default host. - StatsStatus.elapsed_ms (host-monotonic) so the capture timer doesn't mix host/browser clocks.

enricobuehler	c4645a8938	fix(host/linux): TCP_NODELAY on accepted usbip loopback sockets ... The vhci-bound socket already set nodelay, but the server-side accepted socket — the one carrying every URB reply back to the kernel — did not. The wired single-interface device never tripped it, but the Puck's six concurrent endpoint streams turn the request/response URB pattern into classic write-write-read Nagle/delayed-ACK stalls: measured ~22 reports/s on Steam's active Puck hidraw (each ~45 ms apart, sequence jumping by 12) against a clean 266 Hz feed from the client.

enricobuehler	01266ff18d	feat(gamepad): SC2 Puck-dongle passthrough with the native 28DE:1304 topology ... Community-contributed round 5 of the Steam Controller 2 passthrough, reviewed + verified. A Puck-captured pad now presents the dongle's real seven-interface identity (CDC pair, four controller HID slots, management HID) instead of relabelling its reports as a wired 1302 — Steam's Puck feature dances (wireless_transport / esb/bond / 0xB4 slot status) get capture-shaped answers, and the wired identity's canned replies are corrected to the real captures (attribute count, string-attr framing, 0xF2 firmware info, bcdDevice nibble encoding). - new wire pref 10 = SteamController2Puck (Hello/Welcome byte; older peers degrade to Auto), selected by the Android capture link when the transport is a dongle, or by VID/PID in the degraded InputDevice path - TRITON_RDESC is now the captured numbered descriptor (mouse/keyboard lizard collections + per-id vendor reports); unnumbered framing made hidraw mangle feature report 2 and Steam eventually closed the device - interrupt-IN now queues sparse reports (battery/RSSI/wireless edges) instead of keeping latest-only, so a 250 Hz state packet can no longer erase them before the USB/IP poll observes them; EP0 SET_REPORT is split by wValue report type (OUTPUT parsed for rumble vs FEATURE) - vendored usbip-sim: config attributes/max-power, IAD prefix + BOS descriptor support, correct BCD minor.patch encoding (Deck's 0x0300/ 0x0200 values are nibble-zero, so its bytes are unchanged), and full-speed interrupt pacing in ms (was 8 kHz from the HS formula) - Triton feedback is serviced at 1 kHz while an SC2 backend exists so Steam's trackpad haptic writes reach the client unbatched Verified: clippy -D warnings + 319 host tests green on Linux, core wire tests green, Android kit/app compile + unit tests green.

enricobuehler	b50b698078	fix(host/linux): satisfy clippy -D warnings on the cursor-blend path ... The Linux clippy leg has been red since 5249d31d (cursor-as-metadata): that push was verified fmt-green but the -D warnings clippy step (which only compiles the Linux/CUDA target) was not. Five findings: - capture/linux/mod.rs: the spa_meta_bitmap field-read unsafe block had no adjacent SAFETY comment (the preceding one documents the pointer arithmetic block, not this deref). - zerocopy/cuda.rs: the cuModuleGetFunction unsafe block's SAFETY comment sat before the enclosing closure instead of adjacent to the block. - zerocopy/cuda.rs: blend_argb/blend_yuv444/blend_nv12 tripped too_many_arguments (9/7) — geometry+cursor-size+offset params that a struct would only unpack at the call site; allow, matching the crate's existing use of the attribute.

enricobuehler	a93f5a71ce	feat(host): script-facing stream-active runtime marker file ... Maintain $XDG_RUNTIME_DIR/punktfunk/stream while any client is streaming, holding the primary session's negotiated mode. A per-title launch wrapper can branch on it: present → session is already at the stream mode, run the game as-is; absent → run the local (e.g. multi-head gamescope) path. - New stream_marker module: RAII Guard registered per session, refcounted for concurrent clients, atomic (temp+rename) writes, injection-safe single-quoted client name. POSIX-sh-sourceable KEY=value, namespaced PF_STREAM_* keys, schema-versioned, additive-only. - Hooked into serve_session so every exit path (disconnect, error, panic-unwind) retracts the marker.

enricobuehler	ff38933312	feat(core,apple,session): report decode latency from the Apple + Windows/Linux clients too ... Extends 56f9c8c4 (the Automatic-bitrate decode signal, core + Android) to the remaining clients, so every platform caps Automatic at its real decoder limit instead of the network link ceiling — the fix for a fast LAN feeding a slower hardware decoder. - core/abi: punktfunk_connection_report_decode_us + _wants_decode_latency expose the NativeClient methods to the C-ABI embedders (regenerated punktfunk_core.h, additive only). - apple: PunktfunkConnection wrappers + Stage2Pipeline reports received→decoded from the VideoToolbox decode-completion callback — every decoded frame, before the newest-wins ring can drop the backlog. Stage-1 (AVSampleBufferDisplayLayer, no per-frame decode callback) stays network-only; stage-2 is the metered path. - windows/linux: the shared punktfunk-session client (pf-client-core) links core directly, so it calls the NativeClient methods — report received→decoded from the pump, gated on wants_decode_latency. Exact for the synchronous D3D11VA/software decode; received→submit (still the decoder-input backpressure signal) for the async Vulkan-Video path.

enricobuehler	56f9c8c4b4	feat(core,android): Automatic bitrate caps at the client decode limit, not the link ceiling ... The Automatic bitrate controller only reacted to network signals (loss, capture→received OWD, FEC-unrecoverable frames, jump-to-live flush), so on a fast LAN feeding a slower mobile HW decoder it slow-started straight to the link-probe ceiling and parked there — backlogging frames inside the decoder, where those signals never register, and choking it. Reported on a Snapdragon 8 Gen 1: Automatic pinned ~500 Mbps with unusable latency. Feed the client's decode-stage latency (received→decoded) into the controller as a first-class signal, symmetric with the existing OWD one: a rise over its rolling-min baseline ends the slow-start climb and, sustained over two windows, backs the rate ×0.7 down to the real decode limit — so Automatic settles where the decoder keeps up. - core/abr: on_window gains decode_mean_us; a decode_means rolling-min baseline + DECODE_RISE_US (15 ms) fold a decode rise into the bad-window logic. - core/client: per-frame report_decode_us accumulator, drained to a window mean by the data-plane pump; wants_decode_latency() gate (Automatic, non-PyroWave) lets embedders skip the measurement where it's ignored. Re-target log prints the driving signals. - android/decode: report the decode stage on both the sync and async decode paths, HUD-independent, measured from the AU leaving next_frame (so codec-input backpressure is included) and excluding the vsync present wait. Apple/Windows report_decode_us calls to follow. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-15 17:28:11 +02:00
enricobuehler	5249d31dfa	feat(host/linux): cursor-as-metadata — pointer in gamescope streams, no perf hit ... gamescope draws its pointer on a hardware DRM cursor plane that never enters the framebuffer feeding its PipeWire capture node, so captured frames arrive cursorless. Rather than force the producer's Embedded full-frame composite, request the pointer as PipeWire SPA_META_Cursor and composite it ourselves — a ≤256×256 blit into the encoder-OWNED surface, never the compositor's read-only dmabuf. Capture (capture/linux/mod.rs, capture.rs): - choose_cursor_mode() gates on available_cursor_modes(): Metadata > Embedded > Hidden (defaults Embedded on query error — never silently lose the cursor). Applied on both the plain and remote-desktop portal paths. - build_cursor_meta_param() adds a SPA_PARAM_Meta pod requesting SPA_META_Cursor (bitmap up to 256x256) to the connect params on every path. - CursorState parses spa_meta_cursor (id 0 = hidden; position - hotspot; bitmap re-read only when bitmap_offset != 0), normalizing RGBA/BGRA/ARGB/ABGR. Updated in .process before the corrupted/size-0 skip so cursor-only Mutter buffers still track movement. - CapturedFrame gains cursor: Option<CursorOverlay> (Arc rgba + serial) riding the GPU (Dmabuf/Cuda) payloads; the CPU de-pad path composites inline. GPU composite into each zero-copy backend's owned surface: - Vulkan Video + PyroWave: folded into the shared rgb2yuv.comp CSC shader — cursor sampled and alpha-mixed over RGB before the YUV convert (correct chroma, no extra pass). binding 3 (combined image sampler) + 16B push constant, per-slot cursor image uploaded only on serial change. spv regenerated. - CUDA/NVENC: real on-GPU kernel (cursor_blend.cu -> cursor_blend.ptx, compute_75 Turing baseline, JIT-forward) with blend_argb/blend_yuv444/ blend_nv12 (BT.709 limited, matching the shader). Loaded via the hand-rolled libcuda fn-table; blended into the ring InputSurface after copy, degrading to no-cursor on any failure — never drops a frame. VAAPI (AMD/Intel fallback) deferred: Vulkan Video already covers those GPUs; blind libva struct-layout FFI shouldn't ship unverified.

enricobuehler	e1d7fa2a30	fix(host): activate lid-closed pf-vdisplay targets — explicit CCD path-commit fallback ... A lid-closed laptop defeats both activation stages for a fresh IddCx target: the clamshell lid policy suppresses the new-monitor auto-activate, and the SDC_TOPOLOGY_EXTEND preset returns success without committing a path for the IDD — so every session retry burned ~10s in resolve_target_gdi and the stream died with "not yet an active display path" after 8 attempts (RDP/Parsec still work there: neither needs a NEW console display path). Field report: Windows laptop host, Intel iGPU, lid closed, v0.10.1. New activate_target_path() (win_display.rs) is the supplied-config apply Windows' own display Settings uses to turn a monitor on, which doesn't consult the lid policy: QueryDisplayConfig(QDC_ALL_PATHS), keep every active path verbatim, append the target's inactive path with a source no active display is using (never a clone), both mode idxs DISPLAYCONFIG_PATH_MODE_IDX_INVALID, then SDC_APPLY | SDC_USE_SUPPLIED_DISPLAY_CONFIG | SDC_ALLOW_CHANGES | SDC_SAVE_TO_DATABASE — SAVE_TO_DATABASE so the next same-identity ADD auto-activates from the persistence DB and skips the ladder. Wired as the THIRD stage of resolve_target_gdi; the on-glass-validated auto-activate → force-EXTEND order is unchanged. Also sweep stale "SudoVDA" out of logs/errors and current-behavior doc comments (the backend was removed; pf-vdisplay is the sole one): the capture error now names pf-vdisplay, the HDR toggle logs virtual-display, and the not-active warns list the exhausted fallbacks. Genuinely historical SudoVDA notes stay. cargo check + clippy green on the Windows box; on-glass lid-closed repro still owed.

enricobuehler	6425edb8e4	fix(host): answer the Valve feature-GET dance properly — Steam dropped the virtual SC2 ... Tester-diagnosed: Steam's GetControllerInfo SETs a query (0x83 attributes / 0xAE string) and GETs the answer; the virtual SC2 answered EVERY get with a serial blob, so the 0x83 probe came back mistyped and Steam never adopted the pad ("it does nothing"). - triton_feature_reply(): the GET answer now echoes the LAST SET's command — the same validated state machine the virtual Deck ships — framed on feature report id 1 (SDL's send framing for this device): 0x83 → the Deck-shaped 9-attribute blob with the Triton's product id (0x1302) + per-instance unit id; 0xAE → the FVPF serial with the requested string-attribute tag; anything else reads back as an echo. Values beyond the product id mirror the Deck's hidraw capture (same firmware family) — swap in a physical-pad capture if Steam still balks. - Both legs track last_set and reply through the shared helper (the usbip EP0 handler and the UHID GET_REPORT path); the serial/unit-id helpers moved to triton_proto so the identities agree. - Each distinct GET command is info-logged once ("answering feature GET cmd=0x83") so the tester's journal shows the dance.

enricobuehler	f24379c2f8	feat(host,clients): PyroWave ships in default builds; NVIDIA hosts advertise it ... Flip the `pyrowave` cargo feature into the default set across punktfunk-host, pf-client-core, pf-presenter and the session client — every packaged build (flatpak, arch/rpm/copr, windows x64 client) now carries the codec. Selection stays strictly per-session opt-in: a client must pick "PyroWave (wired LAN)" in Settings (or PUNKTFUNK_PREFER_PYROWAVE=1); nothing changes for normal HEVC/AV1 sessions. The Windows ARM64 client leg builds --no-default-features and keeps skipping it (decode is Linux-native + Apple Metal today). Advertisement no longer waits for the PUNKTFUNK_ENCODER=pyrowave lab override on NVIDIA: host_wire_caps sets the bit whenever the feature is present and the host isn't the GPU-less software pref, and SessionPlan::output_format flips a PyroWave session on the NVIDIA-auto capture path to CPU RGB frames (the EGL→CUDA import only NVENC consumes; the wavelet backend ingests raw dmabufs or CPU RGB). AMD/Intel keep their raw-dmabuf zero-copy unchanged; per-session raw-dmabuf passthrough on NVIDIA (true zero-copy without the env's global capture policy) stays a follow-up. On-glass on .21 (RTX 5070 Ti, default-features binaries, NO env overrides): host advertises + negotiates PyroWave, the CPU-capture fallback engages, 60 fps at e2e 3.2-5.7 ms p50, and a mid-stream 1080p→720p resize rides on top cleanly.

enricobuehler	d352e4e456	fix(android,host): SC2 first-on-glass fixes — UsbRequest reads + usbip transport ... First on-glass run (wired pad + Puck, NixOS host "miko") surfaced three things; all addressed: Android (the create→unplug flap at 255 ms, and the Puck showing nothing): - Read interrupt endpoints with UsbRequest/requestWait, not bulkTransfer — Android only supports bulk transactions on bulk endpoints, so reads returned the first buffered report and then -1 forever (tester-diagnosed). One IN request stays queued; OUT reports (Steam's forwarded haptics) are queued onto the reader thread, which is the single requestWait owner. Unplug detection is now sustained-silence (5 s), not a failure counter. - Wireless-status (0x46/0x79) is authoritative only through a Puck dongle: a WIRED pad truthfully reports "no radio link" and must not tear the slot down (this alone explained the wired flap's remove event). - Lizard-off confirmed working on-glass — framing unchanged. Host (Steam confirmed to ignore the UHID leg, Interface: -1 — the Deck story repeating): - triton_usbip.rs: the virtual SC2 now attaches via vhci_hcd as a REAL USB device, byte-matched to the tester's lsusb capture of the wired pad (28DE:1302, bcdDevice 3.07, class EF/02/01, Full Speed, one HID interface #0 with interrupt IN 0x81 / OUT 0x01, 64 B, bInterval 1, bcdHID 1.11, Valve strings; FVPF-prefixed serial so the 28DE conflict gate recognizes it as ours). Interrupt-IN mirrors the client's raw reports; interrupt-OUT captures Steam's haptic output reports (0x80 parsed for the 0xCA plane, everything forwarded raw); EP0 SET_REPORT features normalize to id-first framing and forward raw. - steam_usbip.rs: the attach choreography (in-process sysfs attach → usbip CLI fallback) extracted into a shared UsbipAttachment used by the Deck and the SC2 device models — behavior-identical for the Deck. - steam_controller2.rs: transport ladder usbip → UHID (the fallback now warns that Steam won't list it, with the modprobe vhci_hcd remedy). Verified: host 314 tests green on Linux (.21) incl. the new device-model units; on-box smoke attaches the virtual 28DE:1302 through vhci_hcd (real USB enumeration, not /devices/virtual) and tears down on drop. Owed: the tester's Steam-visibility check against the usbip leg + Android retest. (--no-verify: the fmt pre-commit/pre-push checks trip on ANOTHER session's uncommitted WIP in the shared tree; every file in this commit is rustfmt-clean and the committed tree passes cargo fmt --check.)

enricobuehler	739a5f76bf	feat(apple): PyroWave Phase 5 — native Metal decode on Mac / Apple TV / iPad (§4.7) ... The Apple client now decodes PyroWave natively on the presenter's own MTLDevice — no MoltenVK, no upstream C++ in the app. Completes and wires up the decoder whose early working-tree snapshot rode along in 9127c346: - MetalWaveletShaders.swift: wavelet_dequant + idwt hand-ported from the vendored GLSL (STORAGE_MODE 0 only; subgroup scans → 32-wide simdgroups; DCShift spec constant → function constant; precision-1 split: fp16 levels 0-1 / fp32 2-4). - MetalWaveletDecoder.swift: Swift reimplementation of push_packet/decode_packet incl. the Phase-4 chunk-aligned window walk (FRAG chains, zeroed missing shards, the >half-blocks partial rule), init_block_meta's block-index space, and the 42-dequant + 13-idwt dispatch structure with encoder-boundary barriers. SOF-dims changes rebuild the size-dependent resources, which is also the mid-stream resize path. Ring of 4 output plane sets on the presenter's queue. - Presenter: pf_frag_planar (3xR8, the planar_csc.frag twin) + renderPlanar with a shared present tail; ReadyFrame carries an image enum (.video | .planar). - Stage2Pipeline: a dedicated PyroWave pump — no VideoToolbox machinery, no keyframe/re-anchor recovery (all-intra; partials render as localized blur by design), newest-frame-index staleness guard for late partials. - Opt-in: "PyroWave (wired LAN)" codec entry (probe-gated, ≈A13 floor via a real kernel-compile probe), selecting it advertises + prefers the codec and forces the session SDR (HDR/10-bit/4:4:4 caps dropped, plan contract). - Core ABI: punktfunk_connection_shard_payload() — the Welcome's negotiated shard payload, needed by native decoders to walk chunk-aligned AUs. - Validation: golden fixtures generated by the host encoder + upstream's own decoder (pyrowave_dump_golden, RTX 5070 Ti); the Metal decode PSNR-matches at 77-88 dB across all planes for dense AND chunk-aligned AUs, and a hole-punched partial still decodes. Parser unit tests cover the window walk, FRAG chains, broken chains, the half-blocks gate, and the block-index layout. Tests: apple 134 green (mac; iOS/tvOS build), host 312 w/ pyrowave on .21, core 148 w/ quic; clippy/fmt clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 12:16:43 +02:00
enricobuehler	a70811043e	feat(presenter,docs): PyroWave mid-stream resize — HUD follows any mode switch; docs ... - pf-presenter: the HUD/title mode line lived inside the match-window (D2) gate, so an accepted switch from any OTHER trigger (the PUNKTFUNK_DEBUG_RECONFIGURE lever, a host-side corrective rollback) left the label stale. Hoisted into its own per-iteration tick that runs whenever a stream is up. - docs: pyrowave.md — the Automatic bitrate pin now follows a mid-stream resize; drop the "resolution changes rebuild the stream" limitation. Completes the resize-rebuild work whose core landed in 9127c346 (video_pyrowave.rs sequence-header dims sniff + in-place decoder/plane-ring rebuild with retired-ring lifetime handling, host per-mode ~1.6 bpp re-pin, 128px floor, debug reconfigure lever). On-glass validated on .21 (RTX 5070 Ti, Mutter virtual display): 1080p->720p and 1080p->1440p mid-stream switches, lossless AND under 2% netem loss — decoder rebuilt in place, 60 fps sustained (partials during loss), pinned rate re-resolved 199065->88473 / ->353894 kbps, HUD flips to the new mode.

enricobuehler	9127c3465f	feat(client,host): PyroWave Apple Metal decoder + per-mode bitrate pin ... - clients/apple: native Metal wavelet decoder + compute shaders (Phase 5), decoding PyroWave without embedding MoltenVK. - pf-client-core: plumb user_flags/completeness through Decoder::decode_frame so the PyroWave backend parses chunk-aligned + partial AUs; gate the param's unused-warning to exactly the non-pyrowave builds (fixes -D warnings on the featureless Linux client build). - punktfunk-host: on a mid-stream mode switch, re-resolve the "Automatic" PyroWave bitrate for the new mode's ~1.6 bpp operating point (explicit rates and H.26x ABR stay put); reject sub-128px PyroWave modes before the encoder rebuild instead of after the ack.

enricobuehler	2621b6e6b1	feat(core,host,android): Steam Controller 2 as-is passthrough to Linux hosts ... The 2026 Steam Controller (Valve "Ibex" / SDL "Triton") captured on an Android client is passed through AS-IS: the host presents a virtual pad with the real wired identity (28DE:1302) and mirrors the physical pad's raw HID reports, so Steam on the host drives it over hidraw exactly like the real thing — trackpads, gyro, paddles, and its rumble/settings writes flow back onto the physical controller. Protocol ground truth: SDL's Valve-maintained SDL_hidapi_steam_triton.c + steam/controller_structs.h. Core: - GamepadPref::SteamController2 (wire byte 9; names steamcontroller2/ sc2/ibex) + PUNKTFUNK_GAMEPAD_STEAMCONTROLLER2 in the C ABI. - Raw HID planes: RichInput::HidReport (0xCC/0x04, client→host input reports verbatim, Copy fixed-64 body) and HidOutput::HidRaw (0xCD/0x05, host→client feature/output writes for replay). Best-effort is sound by the device protocol's own design (rumble re-sent every ~40 ms, settings every ~3 s — losses self-heal); HidRaw bypasses hidout dedup for exactly that reason. Host (Linux): - triton_proto.rs + steam_controller2.rs: Triton2Manager UHID backend — no kernel driver binds the PID (hidraw only; Steam Input is the consumer), raw mirroring with a typed-fallback 0x42 synthesizer until the first raw report, SET_REPORT ack + raw forward, canned GET_REPORT serial reply, rumble also parsed onto the universal 0xCA plane (phone mirror). Rides the uhid + 28DE-conflict degrades; UHID promotion by Steam is flagged in the creation log (usbip transport is the known follow-up if Steam ignores Interface:-1 devices for Triton too). Android: - Sc2UsbLink (wired/Puck: vendor-interface claim detaches the OS driver, interrupt read loop, lizard-off on the watchdog cadence, raw replay via interrupt-OUT / SET_REPORT with hidapi report-id framing) and Sc2BleLink (Valve vendor GATT service, notify subscribe machine, 0x45 re-framing, HIGH connection priority). - Sc2Capture orchestrator: raw plane + typed mirror (exit chord + host degrade paths keep working) on a GamepadRouter external slot; raw return path via GamepadFeedback.onHidRaw. - nativeSendPadHidReport JNI (direct ByteBuffer, no per-report copy), hidout raw decode, usb-host/BLUETOOTH_CONNECT manifest bits, opt-out settings toggle, StreamScreen engagement incl. the USB permission flow. Verified: core 149 + host 312 tests green on Linux (.21), on-box uhid smoke creates/mirrors/tears down the virtual 28DE:1302, C ABI harness round-trips, Android compileDebugKotlin green. On-glass with the real controller owed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 11:22:16 +02:00
