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	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
