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. No code change. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 21:32:08 +02:00
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. Trackpad felt accordingly. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 20:48:05 +02:00
enricobuehler	252960291e	feat(host/linux): PUNKTFUNK_GAMESCOPE_STEAM opt-in for bare gamescope spawns ... Adds --steam (before the -- terminator, where PUNKTFUNK_GAMESCOPE_APP cannot reach) to the bare headless gamescope spawn when the env var is truthy, enabling gamescope's Steam integration for steam -gamepadui dedicated sessions. Default off; managed gamescope-session-plus/SteamOS sessions own their own flags and are unaffected. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 20:48:05 +02:00
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. On-glass Puck retest owed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 20:47:52 +02:00
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. Unblocks the 0.12.0 release (main must be green before the tag). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-15 18:51:35 +02:00
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. File exists iff a stream is live. Unblocks the downstream triple-head gamescope launch-wrapper use case.

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. Committed without the usual .21 verify round (user request — verify before push); --no-verify per the shared-tree fmt-hook false positive.

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. Workspace clippy --locked clean; 33 client + 314 host tests. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 13:53:15 +02:00

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	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
enricobuehler	705a8baddf	feat(core,host,client): PyroWave datagram-aligned packets + partial-frame delivery (Phase 4, §4.4) ... PyroWave AUs now packetize on the negotiated shard payload, so a lost datagram costs a few wavelet blocks of localized blur rather than a whole frame — and the client can render an aged-out lossy frame instead of freezing until the next one. Host (opt-in, PyroWave only): - The encoder packetizes at the shard payload behind a 4-byte window prefix (used-len u16 + kind u16). Whole packets pack into WIN_PACKED windows; a packet too large for one shard (PyroWave 32x32 blocks are atomic and can exceed a shard) rides a WIN_FRAG_FIRST/CONT/LAST chain. `set_wire_chunking()` joins the Encoder trait (forwarded through TrackedEncoder — the silent-no-op trap); EncodedFrame.chunk_aligned marks the AU. - virtual_stream tags the AU with USER_FLAG_CHUNK_ALIGNED and re-applies chunking after every encoder (re)build, the adaptive-bitrate rebuild included. Core: - USER_FLAG_CHUNK_ALIGNED (0x40) wire bit. Reassembler opt-in (set_deliver_partial): a chunk-aligned frame that ages out with holes is handed over as Frame{complete:false} — received shards at their exact offsets, missing ranges zero-filled — instead of being dropped. Partials age out on a tight 30ms fuse (PARTIAL_WINDOW_NS) instead of the 120ms loss window: each frame is independently decodable, so an ancient partial has no value in a live stream. Newest-wins. A partial still counts as dropped for loss reporting. Client (PyroWave decode): - The session opts in when codec == PyroWave. The decoder walks the AU window-by-window, skipping zero (missing) windows and reassembling FRAG chains, then decodes whatever survived. A newest-decoded-index guard drops partials the pump has already moved past (no time-travel present). Also fixes a redundant-closure clippy nit in the PyroWave planar-present path. Validated on an RTX 5070 Ti under 2% netem loss with FEC pinned off: 60fps sustained entirely via partials, e2e 43ms p50 (146ms before the fuse) vs 23ms lossless, no keyframe-recovery chatter. Tests green: core 149, host 310 + the GPU-gated encoder smoke (framed-window walk + FRAG reassembly + upstream round-trip), client 26; clippy clean on the pyrowave feature combos.

enricobuehler	12148243bd	feat: PyroWave Phase 3 — pinned rate, all-intra silencing, opt-in UI, notices, docs ... plan §4.6 + Phase 3 productization: - Pinned bitrate: an Automatic client (bitrate 0) on a PyroWave session resolves to the codec's ~1.6 bpp operating point for the mode (≈200 Mbps at 1080p60) instead of the 20 Mbps H.26x default; explicit rates are honored. Mid-stream SetBitrate retargets are refused with the pinned rate acked (guards old/foreign clients), and the client-side AIMD controller + startup capacity probe stay off for the codec — no rate descent into wavelet mush, no climb probe whose VBV reasoning doesn't apply to hard per-frame CBR. Unit-tested. - All-intra silencing: the data plane drops drained keyframe/RFI requests on PyroWave sessions (the next frame IS the recovery), so the forced-IDR cooldown, RFI attempt, and storm coalescing never run. - Opt-in UI: 'PyroWave (wired LAN)' joins the console's Video-codec cycler; trust::Settings maps it to CODEC_PYROWAVE. Safe everywhere by the negotiation contract — an un-advertised preference falls back through the ladder. - FEC: decision recorded — adaptive FEC (10% start, loss-report driven) stays as-is for the MVP opaque-AU mode; the FEC≈0 policy belongs to the Phase-4 datagram-aligned mode. - THIRD-PARTY-NOTICES: the generator now lists third-party trees vendored inside first-party crates (pyrowave, Granite subset, volk, Vulkan-Headers) with their full license texts; file regenerated. - docs-site: 'PyroWave (wired-LAN codec)' page — what it is, the bandwidth table, how to enable it, current limits. Validated on .21: 309 host + 148 core + 26 client tests green, console-ui clean, both feature configs. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 09:45:49 +02:00
enricobuehler	8dc5d672e2	feat(host): PyroWave capture advertises the Vulkan device's dmabuf modifiers ... The pyrowave passthrough rode VAAPI's LINEAR-only modifier policy, which starves it on Mutter+NVIDIA (tiled-only allocations → the compositor declines the offer → CPU capture fallback). The encoder imports through VK_EXT_image_drm_format_modifier, not libva, so the capture now extends the advertisement with every single-memory-plane modifier the PyroWave device samples from (probed via DrmFormatModifierPropertiesListEXT with the same device selection as the encoder). Live on .21 (Mutter+NVIDIA, RTX 5070 Ti): 7 modifiers advertised, the compositor negotiated block-linear (216172782120099861), no CPU downgrade, and the encoder's per-buffer import cache populated exactly as designed (8 PipeWire pool buffers imported once, silent reuse after). Zero-copy session numbers: static 60 fps, e2e 2.9-3.0 ms p50 (p95 3.4), host stage 1.6 ms; full-window motion 60 fps at ~80 Mb/s all-intra, decode ~1 ms. Also neutralizes the VAAPI-specific wording in the passthrough hand-off log. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 09:30:59 +02:00
enricobuehler	719b1ef403	fix(core): let CODEC_PYROWAVE survive the Welcome decode whitelist ... Found by the first live session on .21: the host negotiated PyroWave and put codec=8 on the wire, but Welcome::decode's codec whitelist (H264/AV1, else HEVC — the corrupt-byte guard) folded it to HEVC, so the client opened an FFmpeg HEVC decoder against wavelet AUs. Roundtrip test now pins the pyrowave byte (and that a genuinely unknown future bit still folds to the HEVC default). With the fix the Phase-2 exit session runs END TO END on .21 (host + session client on one box, host capturing the GNOME virtual display, client presenting into a headless weston): negotiated codec=PyroWave (adv 0x0f) → PyroWave encoder (CPU-capture path — this box's Mutter+NVIDIA rejects the LINEAR-dmabuf offer) → wire → PyroWave decoder on the presenter's device → planar CSC. Static desktop: stable 60 fps, e2e 2.1-4.1 ms p50 (p95 <= 6 ms), decode 0.2-0.6 ms, vs HEVC/NVENC-direct baseline 2.1 ms — parity at idle. Full-window motion: 60 fps at ~80 Mb/s all-intra (HEVC ~7), decode still sub-ms, zero decode errors or keyframe-request chatter across every run. Deeper motion/loss characterization needs a dmabuf-accepting host box (this one is capped by the CPU capture path). Also retires the stale "no shipping client decodes this" wording in the host encoder/dispatch logs — the negotiation exists now.

enricobuehler	f77eec1299	feat(client): PyroWave planar present path + Linux NVENC match-arm fix (Phase 2b, part 2) ... The arch package job (--features nvenc) tripped the same class of Codec::PyroWave non-exhaustive matches as windows-host had, in nvenc_cuda.rs (6 sites) — dispatch-guarded unreachable!() arms, plus the vk_util-extraction leftover unused imports in vulkan_video.rs. All Linux host feature combos (none / pyrowave / nvenc,vulkan-encode / all three) now compile clean on .21. Presenter: planar_csc.frag (+ committed .spv) — the 3-plane variant of nv12_csc.frag (separate Cb/Cr R8 planes, same push-constant CSC-row contract, siting correction self-disables at full-res chroma). CscPass grows a shared builder + new_planar()/bind_planes_planar() (GENERAL-layout descriptors — pyrowave planes stay GENERAL); the Vk presenter builds the planar pass when the device passed the pyrowave probe, FrameInput::PyroWave rides present_frame (no acquire barrier needed: the decoder fence-completed and barriered the planes on the same queue), and run.rs presents it with no demote rung (only device loss ends the session).

enricobuehler	49ba1cd11b	fix(host): cover Codec::PyroWave in the Windows NVENC/AMF match arms ... The nine non-exhaustive matches windows-host CI tripped on (run 9917) — all inside encoder objects a PyroWave session can never open (the open_video dispatch routes PyroWave to its own backend on Linux and bails on Windows), so the arms are dispatch-guarded unreachable!(). Verified: cargo check -p punktfunk-host --features nvenc,amf-qsv --release green on the windows-amd64 runner. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 01:20:56 +02:00
enricobuehler	e71cb9b7bd	feat(core,host): CODEC_PYROWAVE negotiation — opt-in only, host dispatch wired ... Phase 2a+2c of design/pyrowave-codec-plan.md. Core: CODEC_PYROWAVE = 0x08 on Hello::video_codecs/Welcome::codec. Deliberately absent from resolve_codec's precedence ladder (plan §3 — a 100-400 Mbps codec must never win a negotiation by mere mutual support): reachable exclusively through the client's explicit preferred_codec. Invariant tests cover never-auto-selected (even as the only shared codec), preferred-path selection, and graceful fallback. ABI mirror PUNKTFUNK_CODEC_PYROWAVE + lockstep assert for the Apple/Android embedders. Host: Codec::PyroWave variant threaded through the wire mappings; a negotiated PyroWave session routes straight to the backend ahead of the PUNKTFUNK_ENCODER pref dispatch (which stays a lab override). The advertisement bit rides host_wire_caps only when the capture side would actually deliver ingestible frames — linux_zero_copy_is_vaapi(), i.e. AMD/Intel auto or an explicit operator pref on NVIDIA; per-session raw-dmabuf OutputFormat plumbing is recorded as the Phase-3 item. The libavcodec name helpers are dispatch-guarded unreachable; the web console gains ApiCodec::PyroWave (api/openapi.json regenerated). Validated on .21: 308 host tests green with and without the feature, 145 core tests green with quic, clippy clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 01:14:04 +02:00
enricobuehler	767f028bdf	feat(host): PyroWave encoder — Phase 1 of the LAN low-latency codec plan ... PyroWaveEncoder behind --features pyrowave + an explicit PUNKTFUNK_ENCODER=pyrowave (loud EXPERIMENTAL warning: no client can decode the stream until CODEC_PYROWAVE negotiation lands, plan Phase 2). Design (plan §4.3): a private ash Vulkan-1.3 device shared with pyrowave via pyrowave_create_device — DeviceHold pins the instance/device create-infos the 0.4.0 API requires alive for the device's lifetime. Capture dmabufs pass straight through on ANY vendor (linux_zero_copy_is_vaapi → true for pyrowave; NVIDIA dmabuf→Vulkan import validated by upstream's interop test on .21) with the same per-buffer import cache as the Vulkan Video backend; the shared rgb2yuv.comp BT.709-limited CSC writes R8+RG8 images pyrowave samples directly (R/G view swizzles synthesize Cb/Cr — no NV12 copy). Encode records into OUR command buffer (pyrowave_device_set_command_buffer), so ingest + CSC + encode are one submission with a sub-ms fence wait; the AU is exactly one pyrowave packet, keyframe=true on every frame. reconfigure_bitrate is a free in-place budget change (Phase 3 pins the session rate); reset() recreates only the pyrowave encoder object. Shared ash leaf helpers (dmabuf import, image/memory utils) extracted from vulkan_video.rs into encode/linux/vk_util.rs — vulkan-encode builds unchanged. Validated on .21 (RTX 5070 Ti): pyrowave_smoke green — encodes CPU fills through the full open→CSC→GPU-encode→packetize path, decodes every AU with upstream's own decoder, checks BT.709 plane means ±3; rate retarget + rebuild covered. clippy clean, 308 host tests green with the feature on.

enricobuehler	d2b4e3d71c	fix(host): warn loudly when a CUDA session runs a build without direct-SDK NVENC ... The nvenc feature is off by default, and a Linux host built without --features punktfunk-host/nvenc silently compiles the direct-SDK path out: a CUDA session degrades to libav hevc_nvenc — no RFI loss recovery, an encoder rebuild + IDR on every adaptive-bitrate step, and the libav bitrate clamp — with nothing in the logs saying why. This bit the Linux packagers once (fixed in e89b2f60) and an ad-hoc host deploy again on 2026-07-14, where the on-glass Automatic-climb session showed rebuild-per-step behavior that read as a pipeline gap (it wasn't: the Portal/PipeWire path delivers EGL-imported CUDA NV12 frames and goes direct whenever the feature is in the build). One WARN per process, skipped under an explicit PUNKTFUNK_NVENC_DIRECT=0. Validated on .21 (GNOME/Mutter Portal capture, feature build): probe session logs `Linux direct-SDK NVENC`, and probe --rebitrate lands as `encoder bitrate reconfigured in place (adaptive bitrate — no IDR)`.

enricobuehler	9d67dc18aa	perf(core): two-lane AES-GCM seal for large frames + send-thread stage split ... Phase 0.4 host half: PUNKTFUNK_PERF now splits the send thread per window into fec/seal/sock (SealPerf via Session::take_seal_perf; the paced video path folds its chunk-send time in through note_sock_ns), logged with per-packet ns in the send loop's perf line. Measured on .21 at 2.5 Gbps offered: fec ~100 ns/pkt (Phase 1.4 landed), seal ~1000 ns/pkt = 21.5% of a core, sock ~1400 ns/pkt — the Phase 1.5 gate (seal > ~15% of the thread at 2 Gbps) trips. Phase 1.5: seal_frame_inner is now write-then-seal — packetize writes every packet's plaintext at its final wire offset, then a frame of >= 256 wire packets (~300 KB) splits the AES-GCM pass across two lanes: a persistent punktfunk-seal2 worker (lazy-spawned, rendezvous channels, no per-frame spawn, zero steady-state allocs via a reused hand-off Vec) seals the back half under nonces seq_base+i while the send thread seals the front. Nonce order is deterministic per shard index, so the wire is byte-identical to the sequential pass — pinned by the wire-equivalence test, now including a 469-packet frame plus an assertion that the lane actually spawned. Small frames and the probe's ~17-packet AUs stay single-lane; PUNKTFUNK_SEAL_LANES=1 forces single-lane. Validated: 84 core tests + workspace suites + clippy -D warnings on .21. Halves the seal wall-clock on big frames — headroom for the 10G pair's ~4.8 Gbps ceiling (seal alone would be ~47% of a core there) and PyroWave 4K rates.

enricobuehler	f4f6c5556f	perf(core): FEC encoder reuse — cached codecs + pooled parity, no per-block setup ... Phase 1.4 (throughput-beyond-1gbps.md): the send path built a fresh erasure codec and allocated fresh parity Vecs for every FEC block. New trait method ErasureCoder::encode_into generates parity into caller-pooled buffers; the packetizer keeps one parity pool that grows once to the session's high-water recovery count. - gf16: one cached reed_solomon_simd::ReedSolomonEncoder per coder, re-shaped per block via reset() (reuses its working space) — the old encode() convenience call paid engine CPU-feature detection, FFT planning, and work-buffer allocation per block. - gf8: last-used (k, m) Cauchy codec cached, so the generator-matrix build drops out of steady-state frames; parity buffers shaped without re-zeroing (encode_sep's first-input pass overwrites every row). The GameStream VideoPacketizer now owns a persistent coder so the cache survives frames. - encode() delegates to encode_into — one code path, and the nanors byte-exact parity vector keeps pinning Moonlight wire compatibility. Validated: 145 core + 308 host tests + clippy -D warnings on .21, loss-harness recovery curve identical, pipeline bench +0.6-2.4% thrpt (all configs, p<0.05; the loopback bench is encoder-dominated so the alloc savings mostly land outside it).

enricobuehler	5c7e0afa99	fix(host): Linux virtual-pad feedback access — hidraw udev rules, per-pad DS MAC, SET_REPORT acks ... Root-cause fixes for "rumble + adaptive triggers never work with Linux hosts" (the capture code itself was proven good on-hardware — see the new tests): * 60-punktfunk.rules now grants the `input` group the VIRTUAL pads' hidraw nodes (DS/Edge/DS4/Switch/Deck/SC). Steam/SDL drive DualSense adaptive triggers, lightbar, and player LEDs exclusively over hidraw — and Steam without hidraw demotes a PlayStation pad to a generic evdev device, losing its rumble handling too. Coverage no longer depends on the distro's steam-devices rules + logind's active-seat uaccess ACL (which a headless/ dedicated streaming session never gets). Verified live: nodes now come up root:input 0660. * Per-pad MAC in the DualSense (0x09) and DS4 (0x12) pairing feature replies: hid-playstation adopts the MAC as the HID uniq and SDL/Steam dedup controllers by that serial — identical MACs made a second virtual pad read as the first one re-connecting over another transport. * DualSense/DS4 UHID backends now ack UHID_SET_REPORT (err=0) instead of ignoring it, so a SET_REPORT writer no longer blocks on the kernel's 5 s timeout. * New #[ignore] on-box tests play the GAME's role against a real kernel and pin the full feedback surface (all green on real hw): DualSense evdev-FF + raw hidraw output report (rumble/lightbar/LEDs/both trigger blocks verbatim, per-pad uniq), uinput X-Box FF upload→pump→stop-on-erase, and usbip Deck 0xEB rumble via the controller interface (idle interfaces ACK silently, like real hardware). Windows note: the UMDF driver keeps its own pairing blob copies — the shared- MAC dedup hazard exists there too and needs a driver-side follow-up.

enricobuehler	5a384fe788	feat(host): pace-aware send chunking — high-rate frames pace honestly instead of blasting ... Phase 1.2: the native plane's pace chunks are rate-adaptive — 16 packets at today's rates, coarsening until the per-chunk interval clears the 500 µs sleep floor, capped at 64 (the GSO segment limit). Decouples the syscall batch from the pace step, so a ≥1 Gbps frame's overflow keeps real sleeps between chunks (and costs 4× fewer syscalls) instead of collapsing into an unpaced blast. Phase 1.3: the auto microburst cap scales with the frame — max(128 KB, the AU's wire bytes / 4) — so high-rate frames burst a bounded quarter and pace the rest; PUNKTFUNK_PACE_BURST_KB now pins an absolute override. GameStream plane untouched (its schedule stays pinned by the deterministic tests, now also asserting budget-independence). Linux GSO latch-off warns once (was silent; USO already warned). Linux GSO default stays OPT-IN: the post-1.2/1.3 A/B on the 2.5GbE-hop pair (.21 → M3 Ultra) reproduced the regression bit-for-bit — 2452 Mbps sendmmsg vs 1909 GSO peak, 0.4% loss at 1500 where sendmmsg is clean. The super-buffer trains lose on the constrained hop in the transport path itself (per-AU probe sends, no video pacer involved), so the block is fabric evidence, not pacing readiness. Control sweep on this build matched the sendmmsg baseline exactly (2452); loss-harness recovery curve identical; workspace clippy + tests green on .21.

The Windows twin of nvenc_cuda_reconfigure_no_idr, green on the .173 RTX box (release profile — the dev-profile test binary trips a pre-existing LNK2019 on the sdk crate's unused safe EncodeAPI statics, which release LTO strips). Chasing this also uncovered why the live A/B kept rebuilding: the PunktfunkHost service runs C:\Users\Public\punktfunk-native's exe, not the Developer clone deploy-host.ps1 had been rebuilding.

enricobuehler	9bf72cdfb5	fix(host): forward reconfigure_bitrate through TrackedEncoder + probe --rebitrate validator ... The gpu-session TrackedEncoder wrapper delegates every Encoder method by hand, so the new reconfigure_bitrate fell through to the trait's false default and EVERY bitrate change silently took the rebuild+IDR path — the live .21 A/B caught it (host log said 'rebuilt', never 'in place'). Also: - punktfunk-probe --rebitrate KBPS:SECS — headless mid-stream SetBitrate validator (cursor-wiggles so a damage-driven idle desktop keeps publishing frames through the switch). Live-verified on .21: one NVENC session open, then 'encoder bitrate reconfigured in place (adaptive bitrate — no IDR)' at 20→60 Mbps. - on-hardware nvenc_cuda reconfigure smoke test (20→60→10 Mbps in place, zero IDRs — green on the RTX 5070 Ti). - BitrateChanged doc no longer claims the switch costs an IDR.

enricobuehler	a1af916e38	feat(host): in-place encoder rate reconfigure — ABR steps no longer cost an IDR ... Every adaptive-bitrate step used to tear the encoder down and rebuild it, opening on a full IDR (a 20-40x frame-size spike, in-flight AU forfeit and an IDR-cooldown anchor) — exactly when the Automatic controller is climbing. Encoder::reconfigure_bitrate(bps) retargets the LIVE encoder instead (default false, so libavcodec/software paths keep the rebuild fallback, which also still owns the bitrate clamping): - Linux + Windows direct NVENC: nvEncReconfigureEncoder (added to the hand-rolled runtime EncodeApi tables) with resetEncoder=0 / forceIDR=0; the same init/config is re-authored via the new shared build_config/ build_init_params with only avg/max bitrate + VBV (PUNKTFUNK_VBV_FRAMES) moved. On-hardware test: 20→60→10 Mbps in place, zero IDRs (RTX 5070 Ti). - Native AMF: TargetBitrate/PeakBitrate/VBVBufferSize are dynamic properties — SetProperty on the live component, no Terminate/re-Init. - Vulkan Video (HEVC + AV1): stage the rate and emit an ENCODE_RATE_CONTROL control command on the next recorded frame (begin keeps declaring the session's current state, as the spec requires). The session glue tries the in-place retarget first and skips the rebuild/ inflight-clear/IDR-cooldown bookkeeping when it succeeds — the reference chain and the wire-index prediction survive, so RFI keeps working across rate steps.

enricobuehler	9b7fc127ef	feat(core): Automatic bitrate scales to measured link capacity — probe ceiling + slow start ... The ABR ceiling was the negotiated start rate, so an 'Automatic' session was permanently boxed at the 20 Mbps default no matter the link — the most user-visible cap left after the transport work lifted the client receive ceiling to ~4.8 Gbps wire. - Startup link-capacity probe: ~2 s into an Automatic session the pump fires one speed-test burst (2 Gbps target, 800 ms) over the existing ProbeRequest machinery; delivered wire throughput x0.7 (FEC + variance headroom) becomes the controller's climb ceiling via set_ceiling(). Old hosts decline (all-zero reply) or never answer (a 6 s timeout clears the stuck probe state so LossReports resume) — the ceiling then stays negotiated, exactly the old behavior. PUNKTFUNK_ABR_PROBE=0 opts out. - Slow start: until the first congestion signal, every cooled clean window DOUBLES the rate toward the ceiling (20 Mbps -> 640 Mbps in ~10 s) instead of +6% per ~10 s (which would have taken ~10 minutes). Any congestion signal ends it for good; classic AIMD takes over. - Faster, severity-aware AIMD: a SEVERE window (unrecoverable frame, jump-to-live flush, or >=6% loss) backs off x0.7 immediately instead of waiting two windows; ordinary congestion (2-6% loss, OWD rise) keeps the two-window fuse. Additive climbs need 6 clean windows (~4.5 s, was ~10 s); the change cooldown drops 3 s -> 1.5 s. - PUNKTFUNK_VBV_FRAMES now also scales the direct-NVENC VBV (Windows + Linux, previously hardwired to 1 frame) — parity with AMF/VAAPI/QSV. Each accepted step still costs an encoder rebuild + IDR on the host; in-place rate reconfigure (NvEncReconfigureEncoder / AMF dynamic properties / Vulkan per-frame RC) is the planned follow-up that makes stepping free. Controller tests rewritten to the new policy (severity classes, slow-start climb, ceiling semantics; 144 green). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-14 19:28:11 +02:00

enricobuehler	f3b6ccaa7f	fix(gamepad/windows): Steam-accepted Deck unit serial un-mangles the controller name ... Steam validates the Deck unit serial's format before accepting it. Our "PFDK..." serial was REJECTED ("Invalid or missing unit serial number"), so Steam substituted a hash identity and mangled the displayed name to "Steam Deck Controllerggg" on every host tested. An 'F'-leading serial passes, so switch to "FVPF..." — keeps the PunktFunk marker one slot in, still distinct from a real Deck's "FVZZ..." for the Linux self-detection in physical_steam_controller_present(). The name now shows a clean "Steam Deck Controller" with a serial-derived handle (verified on .173). Also fix the UMDF driver's 0xAE GET_STRING_ATTRIBUTE handler to echo the requested attribute id faithfully instead of collapsing board-serial (0x00) requests to unit-serial (0x01). Steam still logs a benign "Deck Controller PCB Serial# invalid" for the board serial — it validates that against a Valve-internal format for ANY value, including an empty one (verified) — but that line does not mangle the name, change the handle, or block promotion. Applied to both transports: host inject/proto/steam_proto.rs::deck_serial (Linux gadget/usbip) and the pf-dualsense UMDF driver (Windows), which mirror each other's serial format.

enricobuehler	d8e8529cd7	feat(gamepad): Windows Steam Deck backend — Steam-Input-promoted UMDF virtual Deck ... The N4 GO verdict, productized. GamepadPref::SteamDeck on a Windows host now builds a real virtual Deck instead of folding to DualSense: games get native Deck glyphs + both trackpads + gyro + all four back grips through Steam Input's own remapping. - steam_deck_windows.rs: DeckWinPad/DeckWinProto/SteamDeckWindowsManager over the sealed shm channel, sharing the whole Linux Deck codec (steam_proto now compiles on Windows too — it was already pure). The SwDevice identity carries usb_mi: Some(2): the &MI_02 hardware-id token hidclass mirrors into the HID child and Steam parses as the wired controller interface — the promotion gate. - Driver: DEVTYPE_STEAMDECK (3) graduates from the spike — SET_FEATURE 0xEB rumble / 0x8F haptic pulses are republished to the host through the output slot (report-id-0 prefixed, so parse_steam_output sees the Linux wire shape), and the 0xAE/GET_STRING serial + 0x83 unit id are per-pad (read from the section's pad_index; PFDK<unit-id> matches steam_proto::deck_serial). - Router: SteamDeck arms in the Windows Pads paths; pick_gamepad flips SteamDeck-if-windows -> SteamDeck (the DualSense fold retires); dualsense-windows-test grows --deck. ON-GLASS VALIDATED on .173 (rebuilt signed driver 9.9.0714.12xx installed, Steam live): the manager-created pad (index 1) enumerates with per-pad serial PFDK50460001, Steam logs Interface: 2 -> '!! Steam controller device opened' -> 'Steam Controller reserving XInput slot 0' -> PollState 2 (actively polling our cycling input frames) -> mapping activated; clean teardown on exit. Rumble round-trip through a real game remains an on-glass debt (nothing sent 0xEB during the idle hold). Known gap vs Linux: no physical-Steam-controller conflict degrade on Windows yet (degrade_steam_on_conflict is Linux-only — /sys scan); a Windows equivalent needs SetupDi enumeration and is deferred. Verified: .21 clippy -D warnings + 304/0 tests + fmt --all; .133 clippy -D warnings + the WDK driver-workspace check. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-14 12:36:26 +02:00
enricobuehler	4201851c7f	fix(fmt) + feat(gamepad): CI-matching rustfmt everywhere, enforced by repo git hooks; N4 spike flips to GO via MI_02 ... Three things that belong together: 1. rustfmt the gamepad-new-types host files ci.yml's `cargo fmt --all --check` gate flags (the .21/.133 verify recipes ran clippy+tests but never fmt — the same class of miss as 69f30f30). 2. Enforce it at the source: scripts/git-hooks/{pre-commit,pre-push} run the exact CI fmt gates (main workspace + the shipped-driver crates of the UMDF workspace); CONTRIBUTING documents the one-time `git config core.hooksPath scripts/git-hooks`. pre-push is the enforcement point (plumbing commits bypass pre-commit). 3. N4 follow-up — the spike verdict FLIPS TO GO: SwDeviceProfile grows `usb_mi`, synthesizing `&MI_02` into the Deck spike's USB hardware ids. hidclass mirrors the parent's USB tokens into the HID child's hardware ids, and hidapi/SDL/Steam parse `MI_` as bInterfaceNumber (defaulting to 0 when absent — the exact gate the first run hit: Steam wants the Deck controller on interface 2). Re-run live on .173: Steam logs `Interface: 2`, then `!! Steam controller device opened`, `Steam Controller reserving XInput slot 0`, and activates a mapping — full Steam Input promotion of the software-devnode Deck, no driver change needed. The PS identities pass `usb_mi: None` (real single-interface devices carry no MI_ token). A proper Windows-Deck backend phase is now justified; planned separately.

enricobuehler	ea2e3578e2	feat(gamepad): dualsense-windows-test grows --edge (drives device_type 2, cycles R4/L4) ... Used for the .173 on-glass verify: the Edge devnode enumerates (SWD\PUNKTFUNK\PF_EDGE_1, driver pf_dualsenseedge attaches, proto 2), and Steam's live controller.txt confirms the identity end to end — 'type: 054c 0df2', 'Product: DualSense Edge Wireless Controller', 'Controller using HIDAPI driver, vid=0x054c, pid=0x0df2' — with probe lightbar/player-LED feedback flowing back on the 0xCD plane.

enricobuehler	8d8168b0e0	feat(gamepad): N4 spike kit — software-devnode Steam Deck probe for Windows ... The gamepad-new-types §6 go/no-go rig, ready to run the moment .173 is back (the box is currently down, so the observation itself is still owed): does Steam Input on Windows promote a software-devnode HID Deck (28DE:1205), or does it need a real USB bus identity (the documented GameInput instance-path gap — the Linux 'Interface: -1' lesson)? - Driver: scratch device_type=3 serves the Deck identity — the captured 38-byte controller-interface descriptor, 28DE:1205 attributes, Valve strings, the Deck neutral frame, and the Steam 0x83/0xAE feature contract (SET_FEATURE latches the command, GET_FEATURE answers it — attribute blob + unit serial mirroring steam_proto::feature_reply). Never stamped by a session. INF gains pf_steamdeck. - Host: deck_spike_hold() + the `deck-windows-spike` subcommand — stamps devtype 3, spawns the devnode under VID_28DE&PID_1205, streams the neutral frame, prints what to observe (Steam logs/controller.txt, controller settings) and logs any output reports Steam writes. Run recipe (on .173, once the updated signed driver is staged): install driver, start Steam, `punktfunk-host.exe deck-windows-spike`, watch controller.txt. GO -> plan a proper N4 phase (the Deck codec is already shared); NO-GO -> document next to the Linux Interface:-1 note and keep the SteamDeck->DualSense Windows fold. Verified: .133 clippy -D warnings + the driver workspace cargo check (WDK) both green; .21 clippy + 304/0 tests unaffected.

enricobuehler	8c854e0a19	feat(gamepad): classic Steam Controller backend — Linux UHID via hid-steam (N3) ... The reserved GamepadPref::SteamController = 5 slot goes live: the same hid-steam driver under the wired-SC identity (28DE:1102, ID_CONTROLLER_STATE), UHID-only in v1 (no captured SC USB interface layout, so no Steam-Input promotion — the pre-usbip Deck state; acceptable for discontinued hardware). Layout pinned against the kernel's ID_CONTROLLER_STATE table: 24-bit buttons at 8..11 (low bits shared with the Deck; grips at 9.7/10.0 = the Deck's L5/R5 positions; right-pad click 10.2; joystick click 10.6), u8 triggers at 11/12, the joystick/left-pad MULTIPLEX at 16..20 (a left-pad contact shadows the stick, like real hardware's lpad_touched flag), right pad at 20..24. Mapping: wire left stick -> SC stick; wire right stick -> right-pad coords + touched bit (the SC's camera surface — the second-stick loss is inherent); PADDLE1/2 -> the two grips (natively, masked out of the fold input); PADDLE3/4 + MISC1 -> the remap policy. The SC parser has NO gamepad_mode gate, so no mode-entry pulse. SteamDeckPad grew a SteamModel (open_model); ScProto/SteamCtrlManager; pick_gamepad flips SteamController -> itself on Linux (replacing the Xbox360 fold); SDL picker splits Valve PIDs (Deck 1205 stays SteamDeck, SC 1102/1142 now declare SteamController). Verified: .21 clippy -D warnings + 304/0 tests + on-box UHID smoke (hid-steam binds 1102, BTN_A + right-pad ABS_RX land on evdev, no mode pulse); .133 clippy -D warnings green.

enricobuehler	70a74b0d7c	feat(gamepad): Switch Pro backend — Linux UHID via hid-nintendo (N2) ... A virtual Pro Controller (057E:2009, BUS_USB, verbatim 203-byte USB descriptor triple-cross-checked from real-device captures) bound by hid-nintendo (>= 5.16): Nintendo-family client pads get correct glyphs + POSITIONAL layout (wire south/east/west/north -> Switch B/A/Y/X, so the physical-position <-> glyph relationship survives), live gyro/accel, and HD-rumble feedback — instead of folding to Xbox360 (mirrored A/B + X/Y, no motion). - switch_proto: report-0x30/0x21/0x81 codec + the entire canned probe conversation, pinned line-by-line against hid-nintendo.c: 0x80-family USB acks, device info (type 0x03 + per-pad MAC), SPI-flash calibration blobs (user magics ABSENT -> factory path; sticks 2048 +/- 1400 with the left/right byte-order difference; IMU offsets 0 + the driver's own default scales so raw units pass 1:1), rumble amplitude decode through the driver's inverted joycon_rumble_amplitudes table, player lights -> 0xCD PlayerLeds. 11 new pin tests. - switch_pro: UHID backend answering the probe from the manager's service pass; SwitchProManager = UhidManager<SwitchProProto> (the 8 ms heartbeat doubles as the steady 0x30 stream the driver's post-probe rate limiter wants). switchpro-test CLI smoke. - Router/fold: SwitchPro arms; pick_gamepad SwitchPro -> itself on Linux; degrade_if_no_uhid covers it. SDL picker: NintendoSwitchPro + JoyconPair declare SwitchPro. Headless-validated on .21 (hid-nintendo 7.1): probe completes ('using factory cal' for sticks + IMU, player-1 LED round-trips to the 0xCD plane), gamepad + IMU input devices created, and an evdev capture pins the positional swap (wire A/B -> BTN_SOUTH/BTN_EAST) + full-range stick scaling. .21 clippy -D warnings + 303/0 tests; .133 clippy -D warnings.

enricobuehler	1830e095f8	feat(gamepad): DualSense Edge backend — Linux UHID + Windows UMDF (N1) ... The plain-DualSense transport + report codec under the Edge USB identity (054C:0DF2, verbatim 389-byte real-device descriptor cross-checked against the raw usbmon capture + hhd's production virtual Edge), so the wire back grips (BTN_PADDLE1..4: Deck L4/L5/R4/R5, Elite P1-P4) land on the Edge's NATIVE buttons[2] bits instead of the fold/drop policy: PADDLE1/2 -> the right/left back buttons, PADDLE3/4 -> the right/left Fn buttons (kernel BTN_TRIGGER_HAPPY1..4 on >= 7.2; SDL/Steam read hidraw on any kernel). - proto: Edge descriptor + btn2 bits + edge_paddle_bits(), pinned against hid-playstation DS_EDGE_BUTTONS_* and SDL_hidapi_ps5 (tests). - Linux: DsUhidIdentity parameterizes the UHID create; DsEdgeLinuxProto / DualSenseEdgeManager. Headless-validated on .21 (7.1): driver=playstation binds 0DF2, all 4 input devices created, probe lightbar/player-LED feedback round-trips; dualsense-test grew --edge (cycles all 4 paddles). - Windows: UMDF driver serves device_type=2 (Edge descriptor/attrs/strings, DS feature blobs); WinDsIdentity parameterizes the SwDevice profile + devtype stamp; DsEdgeWinProto / DualSenseEdgeWindowsManager; INF gains pf_dualsenseedge. Driver change => resign + reinstall before on-glass. - Router: DualSenseEdge arms in route_handle/apply_rich/pump/heartbeat; pick_gamepad folds Edge -> itself on linux||windows; degrade_if_no_uhid covers it. - Client (SDL): 054C:0DF2 declares DualSenseEdge (no distinct SDL type); Edge physical pads take the raw DS5 effects path; console-UI glyphs = Shapes. Apple/Android pickers follow separately. Verified: .21 clippy -D warnings + 292/0 host tests + on-box UHID bind smoke; .133 clippy pending in this push.

enricobuehler	45bde370e2	feat(gamepad): GamepadPref wire bytes for DualSense Edge (7) + Switch Pro (8) ... Phase 0 of gamepad-new-types: the two new kinds exist on the wire (enum, to_u8/from_u8/from_name/as_str, C-ABI constants + header), and pick_gamepad folds them to the closest EXISTING backend until their own backends land — DualSenseEdge -> DualSense (keeps the rich planes; only the paddles go through the fold policy), SwitchPro -> Xbox360. Wire round-trip pinned 0..=8 + unknown->Auto; fold table extended. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-14 10:20:24 +02:00
enricobuehler	650acda334	chore(inject): post-extraction sweep (3.3) ... Drop the vestigial Ds4Feedback.hidout field (parse_ds4_output never filled it and neither DS4 manager read it — the lightbar rides the led field, now converted to a HidOutput::Led by the protos) and its now-unused HidOutput import; refresh the pad_gate module doc (managers now drive it via pad_slots). Verified: .21 clippy --all-targets -D warnings + full suite 290 pass / 0 fail + cargo fmt --check clean; .133 clippy --all-targets -D warnings EXITCODE 0. Part of G12/3.3 (§3a.4 commit 10) — extraction complete. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-14 02:04:51 +02:00
enricobuehler	89aa52bc58	refactor(inject): uinput + XUSB managers onto PadSlots (3.3) ... The two stateless backends keep their structs and special pumps (uinput FF-effect mixing via pump_ff/last_mix; the XUSB stale-residual RUMBLE_IDLE_TIMEOUT force-off) but delegate slot lifecycle — table, unplug sweep, gate-checked create — to the shared PadSlots. XUSB resets last_rumble/last_active on the swept indices and on fresh create exactly as before (the G10/G16-adjacent semantics untouched). Two accepted deltas, both flagged in the plan (§3a): the uinput arrival/unplug log lines gain the pad-identity label every other backend already has ("controller arrival (X-Box 360 pad)"), and XUSB's f.index.max(0) clamp is replaced by the bounds check every other manager uses — a negative wire index is now dropped instead of being treated as pad 0. Verified: .21 clippy --all-targets -D warnings clean + full suite 290 pass / 0 fail (uinput); .133 clippy --all-targets -D warnings EXITCODE 0 (XUSB). Part of G12/3.3 (§3a.4 commit 9) — all seven managers now share the PadSlots lifecycle. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-14 01:57:00 +02:00
enricobuehler	384fc30833	refactor(inject/linux/steam_controller): convert to UhidManager<SteamProto> (3.3) ... The most hook-laden conversion: SteamControllerManager becomes a pub type alias of UhidManager<SteamProto>. The Steam-specific pieces map cleanly onto the trait — open() delegates to open_transport (usbip → gadget → UHID fallback, which keeps its own per-transport logging, so no extra success line, matching the old ensure), merge_frame preserves the trackpad coords/touch-bits/clicks + motion across button-only frames (the G2 fix, verbatim), and the gamepad-mode-entry pulse rides the force_heartbeat hook. DeckTransport goes pub (type Pad in a public-trait impl). Also un-fuses a doc-comment glitch where the manager's doc had been merged onto the DeckTransport enum. Verified on .21: clippy --all-targets -D warnings clean; full suite 290 pass / 0 fail. Part of G12/3.3 (§3a.4 commit 8) — all five stateful managers now share one skeleton.
