enricobuehler	c2ae40ef9e	feat(net/mac): default-on recvmsg_x batched Mac recv + GSO host + longer probe ... The Mac/iOS client's wall around ~380 Mbps on a 2.5 G path is the receive drain, not the transport: a loopback speed-test pushes 380/600/1000 Mbps at 0.0% loss, but Darwin has no recvmmsg(2), so the macOS client was doing one recv() syscall per packet — ~40-90k syscalls/s on one core. When the recv loop can't drain fast enough the kernel socket buffer backs up and drops, which the client sees as a sustained stream stalling/freezing in the 300-400 Mbps range (and an immediate "session ended" when a 500 Mbps+ first keyframe bursts in). - core/transport: flip recvmsg_x (the batched Darwin recv, ~30x fewer syscalls) from opt-in to default ON, opt-out via PUNKTFUNK_RECVMSG_X=0. Keeps the auto-fallback to the scalar loop on any unexpected syscall error. The Apple CI swift-test loopback now exercises this path by default. - packaging/kde host.env: enable PUNKTFUNK_GSO=1 — UDP segmentation offload on the host send path (one sendmsg per ~64 packets), the dominant lever above ~1 Gbps. Already wired (send_sealed -> send_gso) with sendmmsg auto-fallback. - apple SpeedTestSheet: lengthen the bandwidth probe 2 s -> 5 s so the measured number stops swinging wildly (50 vs 900 Mbps on the same link) — long enough for steady-state send + recv drain to settle. Matches host MAX_PROBE_MS. - host capture: PUNKTFUNK_SYNTH_NOISE synthetic high-entropy source for reproducible throughput testing of the encode->FEC->send->recv path.

enricobuehler	5bc257f1ae	fix(headless/kde): virtual Punktfunk speaker + restart host with the session ... Audio: a headless host has no speakers, and on a LAN with AirPlay devices PipeWire picks a random HomePod as default — so desktop audio (which the host captures from the default sink's monitor) went to a HomePod over AirPlay instead of to the client, and there was no "Punktfunk" output to select. Ship a `punktfunk-sink.conf` (a `support.null-audio-sink` adapter — NOT the non-existent module-null-sink, which makes pipewire refuse to start) with high priority.session so it's the default; run-headless-kde.sh installs it and restarts pipewire once on first install. The host then captures its monitor and streams it. (Disable AirPlay sinks out of band: `dnf remove pipewire-config-raop`.) Input: the host's libei portal D-Bus connection goes stale when the compositor session restarts the portal under it, and the in-process reopen loop can't recover it (EIS setup keeps timing out) — only a full restart does. Add PartOf=punktfunk-kde-session.service so the host restarts with the session. Both verified live on the Fedora 44 KDE box.

enricobuehler	e4b10f057a	fix(headless/kde): make libei input work headlessly — portal + pre-seeded RemoteDesktop grant ... On a headless KDE appliance, libei input injection silently failed: the EIS socket comes from the xdg RemoteDesktop portal, which never came up, and even up it would pop an unanswerable "Allow remote control?" dialog. Three fixes in run-headless-kde.sh, all idempotent + safe on the dev box: - Reach graphical-session.target: xdg-desktop-portal is ordered behind it and its start job fails without it, but a headless linger session never gets there and Fedora's target has RefuseManualStart=yes — drop that in once, then start the target. - Start the portal with `start` (the old `try-restart` is a no-op when inactive — the first-boot case), so it actually comes up. - Pre-seed the RemoteDesktop grant: vendor the `kde-authorized` permission-store GVariant DB and copy it to ~/.local/share/flatpak/db/ (never clobbering an existing one), so the portal grants RemoteDesktop without a dialog. Shipped by the RPM + .deb. Diagnosed + fixed live on the Fedora 44 KDE box: libei devices RESUME and emit (MouseMove/keys).

enricobuehler	a3a3dfc85b	fix(vdisplay/kwin): make the streamed output the sole desktop (PUNKTFUNK_KWIN_VIRTUAL_PRIMARY) ... On a headless KDE appliance the session has two outputs — run-headless-kde.sh's `kwin --virtual` bootstrap (where plasmashell draws by default) and our per-session streamed output — so the client saw only the wallpaper of an empty extended output (the KWin analogue of the GNOME/Mutter VIRTUAL_PRIMARY issue). New opt-in PUNKTFUNK_KWIN_VIRTUAL_PRIMARY: after creating the virtual output, set it primary via kscreen-doctor (KWin then re-homes the desktop onto it and disables the bootstrap), then belt-and-suspenders disable anything still enabled. The keepalive re-enables the bootstrap on teardown — though KWin also auto-re-enables it when our output is reclaimed, so there's never a zero-output window. Set in packaging/kde/host.env. Verified live on the Fedora 44 KDE box: mid-session the streamed output is the sole desktop at 0,0; post-session the bootstrap is back.

enricobuehler	38b7507440	packaging(rpm): Fedora 44 build + ship the KDE session unit & host.env ... Three changes to make a reproducible Fedora KDE host install: - ci/fedora-rpm.Dockerfile: parameterize the Fedora base (ARG FEDORA_VERSION, default 43) so the same builder produces the Bazzite (F43, libavcodec.so.61) and Fedora 44 (libavcodec.so.62) RPMs. A binary RPM is soname-coupled to its base, so each target Fedora needs its own build/channel. - spec: install punktfunk-kde-session.service (was in the tree but never packaged) with its ExecStart repointed from the dev source tree to the installed run-headless-kde.sh. This is the headless `kwin --virtual` session (KWIN_WAYLAND_NO_PERMISSION_CHECKS=1) the kwin backend needs — an interactive Plasma session refuses to hand its privileged zkde_screencast protocol to an external client, so a dedicated session is required. Not enabled by default (kwin hosts opt in). - ship packaging/kde/host.env as host.env.kde — the ready KWin appliance config (wayland-kde). Validated live on a Fedora 44 KDE box (RTX 4090): KWin virtual output + zero-copy dmabuf->CUDA->NVENC. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-13 16:08:10 +00:00
enricobuehler	340cbcfe22	fix(packaging): point the packaged systemd unit at /usr/bin/punktfunk-host ... scripts/punktfunk-host.service is dev-oriented — its ExecStart references the source tree (%h/punktfunk/target/release/punktfunk-host). When the deb/rpm ship it to /usr/lib/systemd/user, a fresh install with no hand-rolled unit would try to run a binary that isn't there. Rewrite the ExecStart to the installed /usr/bin/punktfunk-host during packaging (sed in build-deb.sh + the spec); the source unit stays as-is for from-source dev. Hosts with a custom ~/.config unit (which shadows the packaged one) are unaffected. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-13 10:25:30 +00:00
enricobuehler	4ff6f447a8	ci(packaging): punktfunk-client .deb + RPM subpackage ... Hook the Linux client into the existing packaging CI: - deb.yml builds both binaries and publishes punktfunk-host AND punktfunk-client to the Gitea apt registry; new packaging/debian/build-client-deb.sh mirrors the host script (shlibdeps auto-Depends — GTK4/libadwaita/SDL3/FFmpeg/PipeWire sonames; no NVIDIA filter, the client links no CUDA). Built and inspected locally on Ubuntu 26.04. - punktfunk.spec gains a "client" subpackage (binary + desktop entry + udev rule); rpm.yml's publish loop picks it up unchanged. - New shared assets: packaging/linux/io.unom.Punktfunk.desktop and scripts/70-punktfunk-client.rules — DualSense hidraw uaccess (USB + Bluetooth, steam-devices style) so SDL's HIDAPI driver gets touchpad/motion/lightbar/triggers instead of degrading to evdev. - Builder images learn the client link deps (rust-ci already had them; fedora-rpm adds gtk4/libadwaita/SDL3-devel) with idempotent install steps in deb.yml/rpm.yml since jobs run against the previous push's image. Workspace check CI (build/clippy/test) already covers the crate since f09def4. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-06-12 23:18:12 +00:00
enricobuehler	0b1322d1c6	fix(packaging): ship the UDP socket-buffer sysctl in the .deb and .rpm ... The host requests a 32 MB SO_SNDBUF, but the kernel clamps it to net.core.wmem_max (~416 KB on a stock box) — so high-bitrate frames overflow the socket buffer and the host drops a large fraction of packets on send (measured 28.5% loss / 54k dropped at 1 Gbps to a clean LAN client on a fresh Bazzite box). scripts/99-punktfunk-net.conf fixes it (32 MB caps) but the packages never installed it. Ship it to /usr/lib/sysctl.d/ (auto-applied at boot by systemd-sysctl) and apply it in the deb/rpm postinst. This is the dominant cause of the sub-Gbps ceiling on an untuned host.

enricobuehler	06346e5037	docs(rpm): use repo_gpgcheck for the unsigned Gitea RPMs ... Gitea GPG-signs the repo metadata but not the individual packages, while its auto-served bazzite.repo sets gpgcheck=1 — so `rpm-ostree install` fails with "could not be verified" on our unsigned RPMs. Document writing the repo explicitly with gpgcheck=0 + repo_gpgcheck=1 (verify the signed metadata, which carries each package checksum) instead of curling the served .repo. Note the TLS-only fallback and that per-package signing is future hardening. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-12 22:07:42 +00:00
enricobuehler	58cb416abb	ci(rpm): publish punktfunk-host RPM to the Gitea registry (Bazzite) ... Mirrors the apt pipeline for Fedora Atomic / Bazzite. New `rpm` workflow builds the host RPM in a Fedora 43 builder image (ci/fedora-rpm.Dockerfile — matches Bazzite's libavcodec.so.61, with a self-contained 16-symbol libcuda link stub so no NVIDIA packages are needed in CI) and uploads to Gitea's public RPM registry (group "bazzite") on every main push (rolling 0.0.1-0.ciN.<sha>) and v* tag (clean X.Y.Z-1). Bazzite hosts then track it with `rpm-ostree upgrade`. - packaging/rpm/build-rpm.sh: git-archive tarball + rpmbuild (--nodeps, since the toolchain is rustup + dnf, not RPMs); copies to dist/, asserts no cuda/nvidia leak. - punktfunk.spec: overridable pf_version/pf_release for CI snapshots; exclude libcuda.so from auto-Requires (NVENC/EGL come from the driver, out of band) — same NVIDIA filter as the .deb; fix a bogus changelog weekday. - docker.yml builds+pushes the new fedora-rpm image; packaging README + rpm/README document the rpm-ostree install/update path (recommended option). Builder image seeded to the registry so rpm.yml's first run finds it. RPM build + clean-Requires verified locally in the image (libavcodec.so.61 / libavutil.so.59, no cuda).

enricobuehler	dfed90bff2	ci(deb): publish punktfunk-host .deb to the Gitea apt registry ... Wires up the half-built Debian packaging: build-deb.sh existed but nothing invoked or published it. Adds a `deb` workflow that builds the release host in the Ubuntu 26.04 rust-ci image, packages it (dpkg-shlibdeps-resolved Depends, NVIDIA driver filtered out), and uploads to Gitea's public Debian registry on every main push (rolling 0.0.1~ciN.<sha>) and v* tag (clean X.Y.Z). Ubuntu hosts then track it with `apt update && apt upgrade`. Also: box-setup docs (packaging/debian/README.md), a pointer from the packaging README, ignore dist/, and drop backticks from the package Description (the unquoted control heredoc ran them as a command substitution).

enricobuehler	a95984bb4f	feat(client-linux): feature parity with the Swift client ... Everything the macOS app does that stage 1 lacked, before any new feature work (user directive): - Input capture is now a deliberate, reversible STATE (Moonlight- style): engaged on stream start and click-into-video (the engaging click is suppressed), released by Ctrl+Alt+Shift+Q (toggles) or focus loss; held keys/buttons are flushed host-side on release; cursor hiding + shortcut inhibition follow the state; HUD hint when released. Per-session window handlers disconnect with the page. - Gamepads: app-lifetime SDL service (GamepadManager parity) — pad list + "Forwarded controller" pin in Settings (auto = most recent), "Automatic" pad TYPE resolves from the physical pad at connect; DualSense touchpad contacts + ~250 Hz motion samples on the 0xCC plane (Swift GamepadWire scale constants); feedback grows adaptive- trigger replay and player LEDs via raw DS5 effects packets (the wire's 11-byte blocks drop into SDL_SendGamepadEffect verbatim); held pad state zeroed on pad switch/detach. sdl3 "hidapi" feature. - Microphone uplink: PipeWire capture -> Opus 20 ms -> 0xCB datagrams (validated live: host received 711 mic packets), Settings toggle. - Speed test per saved host (Swift's "Test Network Speed…"): 2 s probe burst, goodput/loss + recommended ~70 % bitrate, one-tap apply. - Settings: host compositor preference (sent in the Hello), native- display resolution/refresh resolved from the window's monitor at connect (new default), bitrate ceiling to 3 Gbit/s. - Hosts page: saved/trusted hosts section for direct pinned reconnect (mDNS not required), rebuilt on every page return. Deliberately not ported: audio device pickers (PipeWire routing owns this on Linux), resize-to-request_mode (not wired in Swift either), pointer-lock relative mouse (stage-2 presenter, needs raw Wayland). DualSense fidelity needs a physical pad to live-verify. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-06-12 21:11:52 +00:00
enricobuehler	902cc162f7	docs(bazzite): join the input group via ujust add-user-to-input-group ... On Bazzite (atomic rpm-ostree) `sudo usermod -aG input $USER` doesn't stick — /etc/group is managed declaratively, so the change is dropped or reverted on the next update. The supported path is the `ujust add-user-to-input-group` recipe, which edits the group the immutable-OS-correct way. Update the bazzite README + the packaging quickstart + the troubleshooting note (which also now points at the host's "virtual gamepad/DualSense created" vs "creation failed" log as the unambiguous signal).

enricobuehler	136390514d	build: support FFmpeg 7.x and 8.x; fix RPM spec GPU link deps ... punktfunk-host builds unchanged against either FFmpeg 7.x (libavcodec 61) or 8.x (libavcodec 62) — ffmpeg-sys-next auto-detects the system version, and the host's ffmpeg FFI only touches long-stable APIs. Confirmed by building + running live on a Bazzite F43 box (FFmpeg 7.1.3): full gamescope capture → zero-copy dmabuf→CUDA → NVENC H.265 at 1280x720x60, p50 ~0.96 ms. Just doc/spec accuracy, no code change: - encode/linux.rs + CLAUDE.md: drop the "FFmpeg 8 only" claim; note 7.x/8.x both work. - rpm spec: add the missing zero-copy GPU build deps the link actually needs — pkgconfig(gl) + pkgconfig(gbm) (mesa) — and document that -lcuda needs libcuda.so at link time (NVIDIA host, or the CUDA toolkit stub on a headless COPR/koji builder). Tracked for a proper fix: make the cuda/gbm/GL FFI dlopen-based like khronos-egl so the RPM builds on a GPU-less host.

enricobuehler	12b047b0ae	docs(packaging): add end-to-end Bazzite setup guide ... A step-by-step walkthrough for running the host on Bazzite (the immutable Fedora-Atomic gaming distro): the two install paths (rpm-ostree layering vs the bootc image), udev + the `input` group, host.env knobs (gamescope-default), the systemd --user service, firewall ports, verification, and troubleshooting — all grounded in the packaging/ files. Flags the operator-run COPR, the loopback-only mgmt port, and that the bundled unit runs the GameStream `serve` host (not m3-host). Linked from packaging/README.md.

enricobuehler	23bb814bac	feat(packaging): Fedora/Bazzite packaging — COPR RPM, bootc image, gamescope-default config ... Roadmap #3 (install on other devices). Bazzite already ships gamescope + PipeWire + the NVIDIA stack, so the host slots in with minimal new deps (ffmpeg-libs from RPM Fusion + opus + libei). - packaging/rpm/punktfunk.spec — builds punktfunk-host from source (cargo), installs the binary + udev rule + systemd user unit + headless helpers; Requires/Recommends mapped from the Ubuntu bootstrap deps to Fedora. - packaging/bootc/Containerfile — layer punktfunk into a bazzite-nvidia bootc image for atomic, image-based installs. - packaging/bazzite/host.env — gamescope-default appliance config (spawned per session). - packaging/copr/ + packaging/README.md — COPR build-from-SCM settings + install docs (rpm-ostree and bootc paths), and why not Flatpak. - LICENSE-MIT + LICENSE-APACHE — materialize the declared `MIT OR Apache-2.0` (was unfiled); the RPM ships them. Not buildable on the Ubuntu dev box (no rpm tooling) — the COPR/Fedora build is operator-run; all spec-referenced files verified present and the cargo build is green.
