enricobuehler	d2daeacc60	fix(pyrowave): per-session raw-dmabuf zero-copy capture on the Linux NVIDIA host ... A PyroWave session on an NVIDIA-auto host was forced onto CPU-RGB capture (session_plan flipped gpu=false): Mutter blits tiled->LINEAR, we mmap + de-pad ~30 MB, the encoder re-uploads it - three full-frame CPU touches per frame at 5120x1440 while an HEVC session on the same box rides the tiled EGL/CUDA zero-copy. The dmabuf passthrough + Vulkan tiled import were already validated (8dc5d672) but only reachable via the global PUNKTFUNK_ENCODER=pyrowave lab policy. ZeroCopyPolicy gains pyrowave_session (from OutputFormat.pyrowave, i.e. the negotiated codec): the capturer skips the NVENC-only EGL->CUDA importer, takes the raw-dmabuf passthrough, and advertises the wavelet encoder's Vulkan-importable modifiers so Mutter+NVIDIA negotiates tiled zero-copy. The forced-CPU flip in session_plan is gone. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-19 16:25:00 +02:00
enricobuehler	99a1d1bed6	fix(pf-capture): don't require a libspa that exports SPA_VIDEO_TRANSFER_SMPTE2084 ... The GNOME 50 HDR format offer took the PQ transfer id straight from pw::spa::sys, which only exists on libspa new enough to carry the BT2020_10/SMPTE2084/ARIB_STD_B67 block. Ubuntu 24.04 (noble) — the .deb host builder — ships older headers, so bindgen emitted no such constant and the host failed to compile there: error[E0425]: cannot find value `SPA_VIDEO_TRANSFER_SMPTE2084` in crate `pw::spa::sys` This never showed up locally or on the Linux CI: both run a current PipeWire, where the binding is present. It broke deb.yml's build-publish-host job, so v0.14.0 published its client .debs but no host .deb. Spell the id out (14) instead. It's wire ABI, not a private detail — SPA mirrors GStreamer's GstVideoTransferFunction and that block was added as a unit, so the value is the same on every libspa that has the symbol. On one that doesn't, PipeWire fails to intersect the offer and the session negotiates SDR, which is what an HDR-incapable host should do anyway (the path needs GNOME 50+ regardless). A test pins our value against pw::spa::sys wherever the symbol exists, so a renumbered enum fails loudly instead of silently mis-tagging the transfer function. It only builds where tests are compiled — the .deb/.rpm builders run plain `cargo build`, so it can't reintroduce the failure it guards.

enricobuehler	a83acf3ee1	style(fmt): rustfmt the GNOME 50 HDR files under the pinned toolchain ... `feat(hdr): GNOME 50 HDR screencast capture` (0e977817) landed with rustfmt drift — six files were not clean under the pinned 1.96.0 toolchain, so `cargo fmt --all --check` (ci.yml "Format") is red on main. Pure whitespace/ wrapping from `cargo fmt --all`; no semantic change. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-19 10:09:34 +02:00
enricobuehler	3ae5f222d3	fix(hdr): honor SDR negotiation on the Windows host IDD-push path ... A Windows client with HDR off (video_caps=0) negotiates bit_depth=8, but the H.26x IDD-push capture composition FOLLOWED the virtual display's live "Use HDR" state rather than the negotiated depth. On a display whose advanced color was on — leftover from a prior 10-bit session on a reused monitor, the driver default, or the host's global toggle — the capturer emitted P010 and NVENC stamped HEVC Main10 + BT.2020 PQ from the pixel format alone (the in-band HDR upgrade). That 10-bit PQ stream reached a client that advertised SDR-only; on a client whose monitor is HDR-capable but has "Use HDR" off, the PQ landed on an SDR desktop and blew out. Make client_10bit authoritative for the composition depth on BOTH codecs, mirroring the PyroWave branch that already did this: * setup: force advanced color OFF for any !client_10bit session (was pyrowave-only), settling before the ring is sized; * display_hdr gates on client_10bit alone, so an SDR-negotiated session composes SDR even if a physical display forces HDR; * the descriptor poller re-asserts SDR against a mid-session "Use HDR" flip for any SDR-negotiated session (an HDR-negotiated H.26x session still follows flips both ways — its encoder re-inits on the depth change). Only Punktfunk's virtual display is touched, never the host's real desktop. Not yet on-glass; the client-side robustness fix (presenter should tone-map PQ on an SDR-mode display instead of taking an HDR10 swapchain) is a follow-up.

enricobuehler	0e977817f9	feat(hdr): GNOME 50 HDR screencast capture + Linux Main10 encode ... GNOME 50 (Mutter MR 4928, PipeWire >= 1.6) added HDR screen sharing for monitor streams: 10-bit PQ formats (xRGB_210LE/xBGR_210LE) with MANDATORY BT.2020 + SMPTE-2084 colorimetry props, advertised while the mirrored monitor is in BT.2100 colour mode. Wire the Linux host into it end-to-end on the GameStream desktop-mirror path (PUNKTFUNK_VIDEO_SOURCE=portal): * pf-frame: PixelFormat::X2Rgb10/X2Bgr10 (DRM XR30/XB30; X2Bgr10 is the Windows Rgb10a2 layout) + fourccs. * pf-capture: want_hdr portal offer — HDR-only LINEAR-dmabuf pods with MANDATORY PQ/BT.2020 props (SHM excluded: Mutter's SHM record path paints 8-bit ARGB32 regardless of format; tiled excluded: the EGL de-tile blit is 8-bit RGBA8), negotiated-colorimetry parse, generic HDR10 hdr_meta(), packed-10-bit CPU cursor blend, a process-wide SDR downgrade latch on negotiation timeout, and a DisplayConfig BT.2100 colour-mode probe (gnome_hdr_monitor_active). * pf-encode: libav NVENC X2RGB10->P010 swscale (BT.2020 limited) -> HEVC Main10 / 10-bit AV1 with PQ VUI; VAAPI 10-bit on both paths (CPU P010 upload + dmabuf XR30 scale_vaapi p010/bt2020); can_encode_10bit now probes for real on Linux; 10-bit sessions route around the 8-bit-only Vulkan-video/direct-NVENC backends. * GameStream: host_hdr_capable() Linux arm, live monitor-HDR check at RTSP honor time, capturer-pool reuse keyed on HDR-ness, gs_bit_depth covers the new formats. New `punktfunk-host hdr-probe` diagnostic and a PUNKTFUNK_SPIKE_HDR spike lever. * Native plane stays honestly 8-bit via capturer_supports_hdr(): Mutter RecordVirtual streams are SDR-only upstream (GNOME 50 and 51-dev), so virtual-display sources cannot deliver HDR yet. Validated on the RTX 5070 Ti (GNOME 50.3 / PipeWire 1.6.8): the Main10 probes pass and the ignored nvenc_hdr10_smoke GPU test emits an IDR that ffprobe reads as Main 10 / yuv420p10le / bt2020nc / smpte2084 / limited. Live HDR capture negotiation still needs an HDR monitor on glass; VAAPI 10-bit needs the AMD box. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-19 09:30:55 +02:00
enricobuehler	188edde2b3	feat(pyrowave): Windows host HDR + 4:4:4, Rust client HDR present ... Phase 3 of design/pyrowave-444-hdr.md. A PyroWave session now negotiates HDR (10-bit) and 4:4:4 on a Windows host exactly like HEVC/AV1, and the Linux client presents it through the real HDR10 path. Host (Windows): BgraToYuvPlanes becomes mode-aware — SDR/BGRA and HDR/scRGB variants at half- or full-res chroma. The HDR passes reuse HdrP010Converter's exact colour math (scRGB -> PQ BT.2020 limited studio codes, verified by hdr_p010_selftest) but write P010-style MSB-packed codes into two separate shareable R16_UNORM/R16G16_UNORM textures; chroma keeps the pyrowave family's centre-sited 2x2 box. idd_push pins the composition to the NEGOTIATED depth (SDR sessions force advanced color off as before; 10-bit sessions enable it and ride the FP16 ring), and the descriptor poller re-asserts that state instead of following display flips the fixed-format encoder can't. The encoder imports 8/16-bit planes per session and stamps the sequence header's BT.2020/PQ/matrix bits on HDR (stamp_color_bits, extending 574e3e4e's range stamp); supports_10bit/can_encode_10bit/can_encode_444 gates open (HDR Windows-only — Linux capture has no HDR source). Client: the plane ring becomes R16_UNORM for 10-bit sessions (with a STORAGE_IMAGE format probe), the planar CSC pass joins the HDR10 swapchain rebuild (set_hdr_mode previously destroyed it without rebuilding — latent), st.hdr follows frame.color.is_pq(), and the planar push constants carry depth-10 MSB-packed rows + the PQ tonemap mode, identical to the NV12 arm. Verified: .173 (RTX 4090) deploy-config clippy + fmt + wire tests + the extended pyrowave_win_smoke (10-case {SDR,HDR}x{420,444} matrix incl. R16 imports and header stamps); .21 (RTX 5070 Ti) clippy across 4 crates, host 186 tests, client/presenter/encode tests, both Linux GPU smokes.

enricobuehler	ebd9967547	feat(pyrowave): Windows host encoder — separate-plane zero-copy D3D11→Vulkan ... Wire PyroWave into the Windows host (design/pyrowave-windows-host-zerocopy.md). Before this a macOS client + Windows host that both selected PyroWave silently ran HEVC: the host never advertised CODEC_PYROWAVE and open_video_backend bailed. Approach (zero-copy, no GPU→CPU→GPU): pyrowave owns its own Vulkan device (create_device_by_compat, by render-GPU vendor/device-id — NOT LUID, invalid in Session 0). The capturer runs a BGRA→YUV BT.709-limited CSC (matching rgb2yuv.comp) into TWO SEPARATE shareable plane textures — full-res R8 Y + half-res R8G8 CbCr — which the encoder imports into pyrowave's device. Separate single/two-component textures import reliably on NVIDIA at any size; a single planar NV12 import does NOT (the vendored interop test: "only very specific resource sizes" — confirmed on-glass: 1024² fine, 720p/1080p/1440p garbage). A shared D3D11 fence, signalled after the CSC, is imported as a Vulkan timeline semaphore so the wavelet read is ordered after it. - pf-encode: enc/windows/pyrowave.rs (Encoder impl, two-plane import + Linux-style plane views); host_wire_caps advertises CODEC_PYROWAVE on Windows when the backend isn't Software; open_video_backend routes a negotiated PyroWave session first; pyrowave-sys on the Windows target; interop confirmed at open → clean HEVC fallback. - pf-encode: shared, unit-tested enc/pyrowave_wire.rs (single source of truth for the client-facing AU framing); Linux encoder uses it too. - pf-capture: dxgi.rs BgraToYuvPlanes CSC; idd_push.rs pyrowave mode — forces the virtual display SDR (the VideoProcessor can't ingest the FP16 HDR ring), a two-plane shareable out-ring, a shared fence passed every frame (so a rebuilt encoder re-imports it). Threaded via OutputFormat::pyrowave. - pf-frame: D3d11Frame::pyro carries the CbCr plane + fence; OutputFormat::pyrowave. Verified on .173 (RTX 4090): full-host build + clippy -D warnings (nvenc,amf-qsv) + fmt --all --check; pyrowave_wire unit tests; pyrowave_win_smoke GPU test round-trips distinct Y/Cb/Cr (100/180/60) exactly at 1024²/720p/1080p/1440p; Stage-0 interop validated in the real Session-0 service context on-glass. Deployed to the box. Owed: final on-glass picture/latency confirmation. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-18 11:39:44 +02:00
enricobuehler	5e1e64e50b	perf(latency): T2.5b — NV12 compute CSC on the LINEAR/gamescope zero-copy path ... design/latency-reduction-2026-07.md T2.5's Linux half: the LINEAR dmabuf path (gamescope's only offer) fed NVENC RGB, paying its internal RGB->YUV CSC on the SM the game is saturating — the exact contention §5.A removed everywhere else. The Vulkan bridge now carries a buffer-to-buffer RGB->NV12 compute shader (rgb2nv12_buf.comp, BT.709 limited, coefficient-identical to pf-encode's rgb2yuv.comp; whole-word writes so no 8-bit-storage feature is needed): import dmabuf -> dispatch CSC into the exportable buffer -> CUDA de-strides both planes into a pooled two-plane NV12 buffer. PUNKTFUNK_NV12 (default-on) now covers LINEAR; a CSC failure latches RGB for the stream (mid-frame fallback, no dropped frame); 4:4:4 LINEAR sessions stay RGB (never silently subsample). New ImportKind::LinearNv12 rides the existing worker IPC (appended last per the wire-tag rule); cursor stays downstream (blend_nv12). Validated: .21 clippy -D warnings (pf-zerocopy/pf-capture/host+nvenc) + 17 zero-copy tests. Owed: on-glass gamescope session (visual + dmon sm% check).

enricobuehler	bbe4380b41	perf(latency): T1.1 frame-driven encode trigger + T1.4 time-based flush thresholds ... design/latency-reduction-2026-07.md tier 1, remaining halves: - T1.1: the native encode loop wakes on the capture's ACTUAL arrival instead of sampling at a free-running tick — deletes the sample-and-hold (~half a frame interval on average, a full one worst-case: ~8ms avg @60fps). New Capturer::supports_arrival_wait/wait_arrival pair (IDD-push waits its frame-ready event against the shared-header token; the PipeWire portal blocks its channel with a pending stash); backends without an arrival signal — and PUNKTFUNK_FRAME_DRIVEN=0 — keep the legacy tick bit-identically. A 0.9x-interval rate floor caps encode at ~1.11x target when the compositor outruns the session; a +0.5x-interval keepalive keeps static desktops re-encoding at 1.5x-interval cadence. Pacing deadlines re-anchor to the actual submit so they can't drift against the arrival clock. GameStream plane untouched. - T1.4: the jump-to-live detectors run on WALL-CLOCK now (STANDING_TIME / FLUSH_AFTER = 250ms) instead of 30-frame counts whose meaning scaled with fps (500ms @60 but 125ms @240 — and stretching further under T1.1's slower static-scene repeats). The queue trip also requires depth still >= high, so a hysteresis-band hover can't fire on elapsed time alone. Validated: .21 Linux 185 core + 177 host + pf-capture tests, clippy -D warnings; .133 Windows cargo check of pf-capture + punktfunk-host green.

enricobuehler	c8ee4b9902	fix(pf-vdisplay,pf-capture,pf-win-display): pre-split paths in the auto-merged v4 code ... The rename-followed perf hunks still said crate::win_display:: (the pre-W6 layout) — point them at pf_win_display::win_display:: and widen the four helpers they call cross-crate.

enricobuehler	09849906e9	Merge perf/first-frame-latency: driver proto v4 + first-frame/resize latency (P0-P2) ... Brings the first-frame-latency branch (P0.1 transition tracing, P1.1/P1.2 Welcome-time display prep, P2 in-place resize; pf-driver-proto v3 -> v4 with IOCTL_UPDATE_MODES) onto current main. The branch predates the W6.2/W7 splits, so git's rename detection carried most of it into the moved crates (pf-capture idd_push, pf-vdisplay manager/pf_vdisplay, pf-win-display, pf-driver-proto, the driver workspace) and the punktfunk1.rs remainder was re-homed by hand: - native/handshake.rs: welcome/start trace marks + the Welcome-time display prep spawn (the prep thread BECOMES the stream thread; hand-off via a SyncSender<SessionContext>). negotiate() gains bringup/quit/stop and returns the PrepHandle. - native.rs: bringup/resize_ms creation + the stop/quit flags hoisted BEFORE the handshake (the close watcher splits: flags pre-handshake, lifecycle events post-handshake where `hello` exists); punch_done stamp; the data plane adopts the prep thread's result or builds inline. - native/stream.rs: SessionContext/SendStats carry the trace; send_loop finishes it on the first video packet; the resize path gains the in-place fast path (try_inplace_resize) with the full rebuild as fallback, restructured so both share the post-rebuild bookkeeping; prepare_display/PreparedDisplay/ PrepHandle; build_pipeline(+retry) thread the stage marks. - session_status/mgmt: ttff_ms + last_resize_ms per session (union with the lifecycle-events fields main added to the same spots). - pf-capture: Capturer gains capture_target_id() + resize_output() defaults. - pf-vdisplay manager: perf's faster activation poll (60x50ms) + the settle floor before the PnP sweep, on main's knobs/no-trait shape. Also: packaging/windows/build-gamepad-drivers.ps1 is ASCII again (an em-dash from the pf-mouse work tripped windows-host.yml's locale-safety gate on main).

enricobuehler	94ca4041ca	refactor(host/W6.2): extract the frame-capture backends into the pf-capture crate ... capture/linux (PipeWire portal) + capture/windows (IDD direct-push: dxgi mechanics, idd_push + submodules, synthetic_nv12) + pwinit move into crates/pf-capture behind the Capturer trait + synthetic sources (plan §W6). The crate speaks pf-frame (CapturedFrame/PixelFormat + the DXGI identity), pf-zerocopy (CUDA import), and the pf-win-display leaves, and NEVER pf-encode — the capture->encode edge is one-way. This completes the deliberate capture/encode crate split (the invasive path the plan had merged into one pf-media): capture and encode are now separate subsystem crates sharing only pf-frame. Four seams keep the capturer off the orchestrator: - VirtualOutput is EXPLODED into primitives (remote_fd/node_id/preferred_mode/ keepalive) by the host facade, so pf-capture never depends on the vdisplay type; - FrameChannelSender: the sealed-channel delivery is a Send+Sync closure the host facade builds from the pf-vdisplay control device + send_frame_channel IOCTL and hands in; ChannelBroker holds the closure instead of the control HANDLE (the whole-desktop handle-duplication security boundary is byte-for-byte unchanged); - console_session_mismatch + desktop_bounds live in pf-win-display (leaf peers); - pwinit moves here (audio caller -> pf_capture::pwinit). The host keeps capture.rs as a thin BRIDGE: it re-exports the vocabulary + capturer types (every crate::capture::* path is unchanged) and keeps open_portal_monitor / capture_virtual_output, which resolve the ZeroCopyPolicy + FrameChannelSender and call into pf-capture. verify_is_wudfhost + install_gpu_pref_hook are re-exported (the gamepad-channel bootstrap + the main.rs subcommand consume them). Co-developed: the resident-HID-mouse compose-kick hook (HID_COMPOSE_KICK + the HID-first cursor kick + _display_wake) rides this commit into pf-capture; the host mouse_windows registration side lands separately on top. Verified: Linux clippy -D warnings (pf-capture + host nvenc,vulkan-encode,pyrowave --all-targets) + host tests 299/299; Windows clippy -D warnings (pf-capture --all-targets + host nvenc,amf-qsv --all-targets) Finished exit 0.
