Field report (RX 5700 / SteamOS): 10-bit HEVC "unsupported" — but the GPU was
never the blocker (RADV probed Main10 fine on that box). The session stayed SDR
because stock gamescope offers no 10-bit PQ capture formats and nothing shipped
our pipewire-hdr build outside the Bazzite sysext, while PUNKTFUNK_GAMESCOPE_HDR
additionally defaulted off everywhere. Close all three gaps:
- PUNKTFUNK_GAMESCOPE_HDR now defaults ON (explicit-off grammar, the flip the
config comment planned post-canary). Safe by construction: the +pfhdr banner
probe, managed-spawn term, and client 10-bit cap keep stock-gamescope boxes on
the exact 8-bit path. The nix module's gamescopeHdr (default true now) only
controls whether the patched binary is on PATH; it no longer sets the env.
- SteamOS: new scripts/steamdeck/build-gamescope.sh builds the HDR gamescope in
the same pf2 trixie distrobox (apt dep list validated by a full build in a
debian:trixie container), installs ~/.local/bin/punktfunk-gamescope, and
maintains PUNKTFUNK_GAMESCOPE_BIN in host.env ONLY while the binary passes its
on-glass --version/+pfhdr check — a stale absolute override would break
session spawning, not just HDR. Wired into install.sh (§3b), update.sh
(retrofit), and rebuild-check.sh (ldd-probes it like the host binary).
- Arch: build-sysext.sh gains a --gamescope fold-in (banner-verified by
execution, host-image-only), and punktfunk-host optdepends the companion.
Deliberately NO CI-published host sysext: per the 2026-07-22 packaging
verdict a prebuilt SteamOS host breaks on A/B soname bumps (and /var is
per-partition-set), so arch.yml records that instead — SteamOS hosts use the
distrobox flow above.
Also fixes a latent bug that made build-sysext.sh fail every invocation as
documented: a literal `}` inside `${1:?usage …{host,client}…}` terminates the
expansion early and corrupts $PKG (caught by the new synthetic-package test,
which also covers the fold-in, the unmarked-gamescope refusal, and the
client-image guard).

# punktfunk — SteamOS post-OS-update self-heal (runs before punktfunk-host at session start).

|
|
# The host binary links SteamOS system libraries (FFmpeg, PipeWire, libva, …). A SteamOS A/B
|
|
# update that bumps a soname leaves the binary unable to load — a silently dead host until
|
|
# someone remembers to re-run update.sh. This probe is the reliability backstop:
|
|
# * healthy binary → exit in milliseconds (every normal boot);
|
|
# * loader breakage → run scripts/steamdeck/update.sh (rebuild host + web + runner against
|
|
# the new library tree, restart services). The build container, source, and cargo caches
|
|
# all live under /home, which SteamOS updates never touch — so the rebuild is warm.
|
|
#
|
|
# Root is NOT needed: the /etc system tuning survives updates via the atomic-update keep list
|
|
# (see punktfunk-atomic-keep.conf); only the binary has to chase the OS libraries.
