enricobuehler	9f92dc505b	fix(client/pkg): ship 32MB UDP recv-buffer sysctl with the Linux client ... The client asks the kernel for a 32 MB SO_RCVBUF, but the kernel silently clamps it to net.core.rmem_max — whose default is far too small. A too-small recv buffer is the dominant client-side wall above ~1 Gbps. Measured live (Fedora host -> two clients, real 2.5G LAN, GSO off): a client capped at 4 MB rmem_max dropped 31.6% of a 2 Gbps stream at the receiver, while a 32 MB client delivered the same 2 Gbps at 0.0% loss. The host already shipped this tuning; the client packages didn't (the RPM's %post even referenced the host-only file), so a client-only install streamed lossy at high bitrate. Add scripts/99-punktfunk-client-net.conf (rmem/wmem = 32 MB, distinct filename so host+client can coexist) and ship+apply it from both the .deb (build-client-deb.sh) and the RPM client subpackage (install, %files client, %post client). For reference the full ladder (punktfunk speed-test): 0% loss to 1.5 Gbps on a 4 MB client; 31.6% at 2 Gbps on 4 MB vs 0% at 2 Gbps on 32 MB. iperf3 put the raw link at ~2.35 Gbps TCP / ~2.4 Gbps UDP, so the stack now tracks the wire given a big enough recv buffer.

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	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	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	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	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.
