CI currently rebuilds every recipe on every push. distcc-avahi hasn't
changed in weeks but still burns runner-time. Add a small bash helper
that takes a recipe dir (arch/<n> or debian/<n>), resolves the expected
pool URL on packages.reauktion.de, and prints `skip=1` or `skip=0`.
Live-tested against all 14 recipes. Sources PKGBUILDs in a sandboxed
subshell so epoch=, ${_pkgver/-/}, and pkgname=() arrays resolve
correctly. For debian/*, extracts top-level PKGVER/PKGREL lines with
an awk guard that rejects command-subst and embedded-command
assignments (avoids false-positive matches against HEREDOC-quoted
dkms.conf content).
Wiring into build.yml lands in the next commit.
iter9 of the panvk-bifrost campaign — operator-confirmed Vulkan output
on PineTab2 (Mali-G52 r1 MC1) 2026-05-20.
Patches Mesa 26.0.6's PanVk Vulkan driver:
- VK_KHR/EXT_robustness2 + nullDescriptor exposed for PAN_ARCH 6/7
- has_vk1_1 / has_vk1_2 = true on Bifrost
Patches applied via sed in PKGBUILD prepare() (cleaner than maintaining
a Mesa fork for two two-line tweaks; upstream context drifts between
Mesa releases would make a literal .patch brittle).
Co-installs at /usr/lib/panvk-bifrost/ — stock mesa untouched. Stock
libvulkan_panfrost.so and its ICD JSON keep working for everyone not
opting into the patched driver.
Ships /usr/bin/brave-vulkan that wires up:
VK_ICD_FILENAMES=/usr/lib/panvk-bifrost/icd.json
PAN_I_WANT_A_BROKEN_VULKAN_DRIVER=1
MESA_VK_VERSION_OVERRIDE=1.2 # ANGLE needs apiVersion>=1.1; the
# has_vk1_x flags don't move it, so
# the env-var override carries that
brave --use-gl=disabled --enable-features=Vulkan --use-vulkan=native
--ozone-platform=x11 --no-sandbox --disable-gpu-sandbox
--ignore-gpu-blocklist "$@"
Side-steps the stock "GLES3 is unsupported / GPU process exits" failure
documented in panvk-bifrost/README's "Consumer-side benefit" section.
Known limitation: WebGL/WebGL2 in-page won't work — ANGLE needs GLES3
which needs VK_EXT_transform_feedback, which PanVk-Bifrost doesn't
currently support. Browser chrome + standard page rendering work fine.
Gitea Actions job mesa-panvk-bifrost-aarch64 added to build.yml,
patterned on libva-v4l2-request-fourier-aarch64. Mesa build is slow
(~30-60min on actrunner-aarch64). Standalone (no needs:),
continue-on-error so it doesn't block other jobs.

481279c adds packaging/systemd/{daedalus-v4l2.service,modules-load} to
the upstream tree. This commit wires those into both the Arch
(PKGBUILD + .install) and Debian (build-deb.sh + postinst/prerm/postrm)
package layouts so that a fresh install of daedalus-v4l2 + daedalus-
v4l2-dkms on a Pi 5 leaves the kernel module loaded at next boot AND
the userspace broker daemon enabled — no manual modprobe / systemctl
enable dance needed.
arch/daedalus-v4l2:
* pkgver 0.1.0.r18.481279c, pkgrel reset to 1 (new upstream pin).
* Dropped 'systemd-libs' from depends — daemon doesn't link
libsystemd (no sd_notify); the .service unit is consumed by
systemd-the-init, no link-time dep required.
* package() now installs the .service to
/usr/lib/systemd/system/daedalus-v4l2.service and the modules-
load drop-in to /usr/lib/modules-load.d/daedalus-v4l2.conf.
* New .install file: post_install/post_upgrade run daemon-reload +
enable + systemd-modules-load + try-restart on upgrade; pre/post
remove tear down cleanly. No auto-start — operator decides.
arch/daedalus-v4l2-dkms:
* pkgver bump to 481279c, pkgrel reset to 1. Kernel module itself
is bit-identical to f0cd29a (commit only touches packaging/) but
bumping in lockstep keeps DKMS source-tree pkgver matched to the
userspace pkgver so /etc/modules-load.d points at a module that
actually exists.
debian/daedalus-v4l2:
* Same bump 481279c, PKGREL=1.
* build-deb.sh stages /lib/systemd/system/ + /usr/lib/modules-load.d/
and installs both files.
* Generates DEBIAN/postinst that runs daemon-reload, enables the
service, triggers systemd-modules-load, and conditionally starts
the service iff /dev/daedalus-v4l2 is already present (uses the
same ConditionPathExists= guard as the unit file so apt install
doesn't fail loudly on a host where dkms hasn't built yet).
* Generates DEBIAN/prerm (stop + disable on remove) and
DEBIAN/postrm (daemon-reload).
debian/daedalus-v4l2-dkms:
* Lockstep version bump, PKGREL=1. Postinst (loud-warn-on-missing-
headers) unchanged.
Verified the SHA via local rev-parse against ~/src/daedalus-v4l2 —
481279c is the "packaging/systemd: ship daedalus-v4l2.service +
modules-load drop-in" commit on main.

DKMS build for daedalus_v4l2 fails against kernel 6.18+ with:
daedalus_v4l2_main.c:1049: error: too few arguments to function
'v4l2_fh_add'
v4l2-fh.h:97: void v4l2_fh_add(struct v4l2_fh *fh, struct file *filp);
(same for v4l2_fh_del). Signature changed exactly at v6.18 — verified
v6.13–v6.17 still use the one-arg form via raw.githubusercontent.com
tag walk.
Upstream commit f0cd29a wraps the calls with LINUX_VERSION_CODE so the
module keeps building against:
* 6.12 LTS / RPi 6.12.75 (one-arg) — hertz
* 6.12.88+deb13-arm64 (one-arg)
* 6.18.29+rpt-rpi-2712 (file* arg) — higgs running kernel
Higgs (Pi CM5) was hitting this: daedalus-v4l2-dkms 0.1.0+r16+gf55b2cd
showed 'installed' in dpkg but DKMS autoinstall failed for the running
6.18.29 kernel. Re-running 'dkms autoinstall' after this bump succeeds
+ /dev/daedalus-v4l2 appears.
Also widens debian/daedalus-v4l2-dkms Recommends from
linux-headers-generic | linux-headers
to
linux-headers-rpi-2712 | linux-headers-rpi | linux-headers-generic | linux-headers
so apt pulls the right metapackage on Raspberry Pi OS / RPi-2712
kernels by default.
Userspace pkgver bumps in lockstep (no userspace change in f0cd29a, but
keeps daedalus-v4l2 + daedalus-v4l2-dkms versions matching for
LIBVA_DRIVER_NAME selection sanity).

Stock firefox.desktop disappears when our 'provides=firefox' replaces stock
firefox-arch, so installing firefox-fourier left the user without a Plasma/GNOME
start-menu entry. Add firefox-fourier.desktop with Categories=Network;WebBrowser;
(routes under Internet on KDE Plasma 6), MIME types for the usual web schemes,
new-window / private-window actions, and the 128px icon from the package's
internal browser/chrome/icons tree.
Reported on ohm (PineTab2 / Plasma 6) — manual /usr/share/applications shim
proved the file works; this commits it to the recipe so future installs Just Work.
Bumps pkgrel from 5 to 6. Cumulative regenerated from the redone
per-series reconstruction in kernel-agent (replacing the broken
PR #33 attempt with a proper rebase onto v7.0-danctnix1 baseline).
cumulative.patch: 162 716 -> 279 554 bytes
b2sum: 50397711a6a3... -> eb179c03f35a...
manifest.lock: 32 resolved patches (was 4 — c5x interim collapsed
the bes2600 driver scope into one cumulative blob;
per-series properly tracks each fix)
bes2600 series-dirs in kernel-agent: now 25 individual series-dirs
(one per cleanups commit + Patch H), each with the
proper in-tree drivers/staging/bes2600/* paths
Built + installed on ohm 2026-05-19 23:39. Functional verification:
uname: 7.0.0-danctnix1-6-pinetab2-danctnix-besser
srcversion: 1A919EED0E6DC2478559B17 (differs from pkgrel=5's
BEB625FA7443171EA8D55F7 — not byte-equivalent;
functional equivalence verified: wlan0 associates,
bes2600_btuart loads, Pattern A 0, no WARN/BUG)
Per-fix revertability now real: removing an include from
fleet/ohm.yaml drops that fix from the cumulative. Bisecting on
kernel-agent side becomes practical.
The recipes pinned `f55b2cdab8a8c0bc04e8c1bb1d0b6ca85e7d96d2` as the
"Phase 8.13: byte-exact end-to-end via libva" commit, but that SHA
does not exist in git.reauktion.de/reauktion/daedalus-v4l2.
The actual `main` tip (per gitea's for-each-ref) is
`f55b2cd002afdfd08f3c093627317f92e4929074` — same 7-char prefix
(`f55b2cd`), different full hash. Likely a manually-constructed SHA
based on a short prefix from a working copy that was never pushed.
git archive --format=tar.gz on the bad SHA fails with
fatal: not a tree object: f55b2cdab8a8...
which surfaces as 500 from Gitea's archive endpoint, which curl in
the CI build-deb.sh sees as `curl: (22) ... error: 500`.
Diagnosed by tailing gitea.log during a fresh archive request from
the CI runner; the underlying `git archive` command in the gitea
container is logged with the full failing SHA + error.
Fixed in all four recipes (arch + debian, daedalus-v4l2 + dkms).
pkgrel bumped to signal new build (PKGVER short-prefix `gf55b2cd`
stays the same — both bad and good SHA share that prefix).
Stock Debian trixie ships FFmpeg 7.1 (libavcodec.so.61), our fork
ships FFmpeg 8.1 (libavcodec.so.62) — different SONAMEs, NOT a
drop-in for trixie's libavcodec61-consuming desktop. Previous
Conflicts: libavcodec61, libavformat61, ... triggered apt to remove
~50 packages (kde-plasma-desktop, vlc, dolphin, ...) when a user
just wanted ffmpeg-v4l2-request-fourier installed alongside.
This commit:
1. ffmpeg-v4l2-request-fourier (pkgrel=2):
- --prefix=/opt/fourier (instead of /usr)
- --extra-ldexeflags / --extra-ldsoflags: -Wl,-rpath,/opt/fourier/lib
so /opt/fourier/bin/ffmpeg finds its own libs without external help
- Ship /etc/ld.so.conf.d/fourier.conf with /opt/fourier/lib + ldconfig
in postinst/postrm. dlopen-by-SONAME consumers (firefox, daedalus)
find libavcodec.so.62 via ld.so cache without LD_LIBRARY_PATH.
- Drop ALL Conflicts/Replaces/Provides for libav* / libpostproc /
libsw* — no SONAME clash with stock libavcodec61, no reason to
evict anything.
- /usr/bin/ffmpeg-fourier + ffprobe-fourier convenience symlinks.
2. daedalus-v4l2 (pkgrel=2):
- Depends: ffmpeg-v4l2-request-fourier (>= 2:8.1+rfourier)
instead of stock 'ffmpeg (>= 7.1)'. The daedalus binary was
linked against libavcodec.so.62 at build time (CI runner had
marfrit/ffmpeg-v4l2-request-fourier installed); at runtime it
needs the .so.62 that only the fourier pkg provides.
Not touched:
- libva-v4l2-request-fourier: ships only v4l2_request_drv_video.so
at /usr/lib/<triplet>/dri/ which libva dlopens by file pattern.
Path A would break the lookup unless every consumer launcher sets
LIBVA_DRIVERS_PATH. Driver name is unique; no conflict. STAY.
- mpv-fourier: Depends already correctly bound to fourier ffmpeg.
Will receive libavcodec.so.62 via the ld.so.cache mechanism
above without recipe changes.
Two deterministic CI failures from run 115 (PR #34 wiring):
mpv-fourier-debian (task 566): dpkg-deb refuses `Conflicts: pkg1 |
pkg2` — Debian policy doesn't allow alternatives in Conflicts.
Split into separate entries.
daedalus-v4l2-debian (task 563): pacman -Syu pulled stock arch
ffmpeg which conflicts with the already-installed
ffmpeg-v4l2-request-fourier left behind by the earlier
mpv-fourier-aarch64 job (it configures [marfrit] + pre-installs
the fourier ffmpeg). Drop 'ffmpeg' from the pacman line; mirror
the [marfrit]+pre-install step from mpv-fourier-debian. Daedalus
only needs libavcodec/libavformat headers which the fourier
package supplies.
The debian/{ffmpeg-v4l2-request-fourier,libva-v4l2-request-fourier,mpv-fourier,daedalus-v4l2,daedalus-v4l2-dkms}
recipes have been sitting in the tree with no CI trigger since 2026-05-18.
build-deb.sh exists and is runnable, but nothing fires it — so no .debs
were ever pushed to packages.reauktion.de/debian/pool/.
Mirror the lmcp-debian / claude-his-debian pattern: build natively on
the arch-aarch64 runner (dpkg-deb is in extra), rsync the .deb to
hertz's incoming dir, trigger publish-deb for bookworm + trixie.
mpv-fourier-debian also pre-installs ffmpeg-v4l2-request-fourier from
[marfrit] for libavcodec ABI symmetry, matching the arch sibling job.
fermi's makepkg.conf already has BUILDENV=(distcc ...) which prepends
/usr/lib/distcc/bin to PATH at build time. But Mozilla's mach
configure picks CC/CXX from the environment directly — it doesn't
treat the distcc shim in PATH as the default C compiler unless the
env vars are set explicitly. Without this guard the distcc workers
sat idle while mach drove a local-only build.
Mirrors the explicit-distcc pattern already used in
ffmpeg-v4l2-request-fourier/PKGBUILD.
Caveat documented in the comment: only the C/C++ portion
distributes. rustc and host-only build steps stay local. Empirical
~30-40% wall-clock improvement on a 4-worker pool (tesla, dcc1, dcc2,
ampere via Avahi zeroconf).
pkgrel bumped so a rebuild publishes a new package even though the
binary output for users is unchanged (build process speedup only).

`package_qt6-xcb-private-headers-fourier()` depended on
`qt6-base-fourier=$pkgver` (= literal "6.11.1"), but the package itself
ships with `epoch=1` so the installed version is `1:6.11.1-1`.
Pacman's strict-equality version compare treats "6.11.1" as epoch=0 and
"1:6.11.1" as epoch=1 — mismatch — and refuses every upgrade involving
qt6-xcb-private-headers-fourier with "unable to satisfy dependency".
Fix: include the epoch prefix in the dep string —
`qt6-base-fourier=$epoch:$pkgver`. pkgrel bumped to 2 so the rebuild
publishes a new package even though only the dep string changed.
Observed on ohm 2026-05-18 after the broader fleet pacman -Syu —
worked around there with --assume-installed; this fixes it properly.

The PR branch contained the unpacked Linux 7.0 source tree
(~81k files, ~38M additions) under src/. These are makepkg build-dir
artifacts that should never be committed; PKGBUILD downloads + extracts
them at build time.
Their presence inflated the PR file-count display to 81030 changed
files. Removed src/ from tracking and added a stronger .gitignore
in the package dir to prevent regressions.

Bumps all 4 daedalus packages (arch + debian × userspace + dkms)
to pick up daedalus-v4l2 f55b2cd: "kernel: media_request_get/put
around inf->req (UAF safety)".
Closes the SHIP-WITH-EYES-OPEN concern Sonnet flagged in the
pre-deployment review — without explicit media_request_get on
capture + media_request_put on completion, a concurrent
MEDIA_IOC_REQUEST_REINIT or process-kill triggering
buf_request_complete from the cancel path could drop vb2's
reference before our completion handler ran, leaving inf->req
dangling through v4l2_ctrl_request_complete + buf_done.
Matches the cedrus / rkvdec refcount pattern. No protocol
change, no API change, no consumer-side adjustment required.
Same byte-exact output verified on hertz post-fix (libva path:
match; standalone test_m2m_stream: 30/30 frames).

Sonnet pre-deployment review caught a BLOCKER: on a fresh higgs
(Debian 13 / Pi CM5) install without the RPi kernel headers
pre-installed, the postinst's `dkms autoinstall || true` silently
swallowed the build failure. Package appeared installed but the
.ko was absent; `modprobe daedalus_v4l2` then failed and the
entire stack was dead with no clear pointer to the cause.
Fix in both ecosystems:
debian/daedalus-v4l2-dkms/build-deb.sh:
- After `dkms autoinstall`, verify the post-condition with
`dkms status -m daedalus_v4l2 -v VER -k $(uname -r)`.
- If the module isn't 'installed' / 'loaded' for the running
kernel, emit a yellow-bolded ANSI warning naming the most
likely cause (kernel headers package missing) and the exact
recovery steps (linux-headers-rpi-2712 for RPi or
linux-headers-$KERNELVER for Debian generic, then
`dkms autoinstall` + `modprobe`).
- Colour only on TTY; the warning is unconditional regardless.
arch/daedalus-v4l2-dkms/:
- New daedalus-v4l2-dkms.install with post_install +
post_upgrade hooks that run the same `dkms status` check.
- post_upgrade catches the case where a kernel-headers package
was uninstalled / pruned between upgrades, silently
regressing the build.
- Wired into the PKGBUILD via install="${pkgname}.install".
Both versions point at the actual repair commands rather than
just saying "build failed", so the user is one apt/pacman away
from a working stack instead of debugging dkms internals.

Installs kernel/ source to /usr/src/daedalus_v4l2-<ver>/ with

PKGBUILD pinning the same daedalus-v4l2 @ f04d700 as the
userspace sibling. Installs kernel/ source to
/usr/src/daedalus_v4l2-<ver>/ with a generated dkms.conf;
AUTOINSTALL=yes builds the module against the running kernel.
The kernel/ Makefile uses -I$(src)/../include for the shared
protocol header. In the userspace tree that's daedalus-v4l2/include/;
for DKMS we flatten by copying the header into kernel/include/
and patching the Makefile in package() to point there.

kernel-agent corrected the @@ hunk counts in the SCS xor-neon patch
(the previous -9,7 +9,12 'fix' was an overcorrection; actual is
-9,6 +9,11). pkgrel=4 build #4 silently tolerated the wrong counts
because the trailer was stripped, but pkgrel=5 with besser#18
behind SCS exposed the inconsistency.
b2sum: ceec602afa8574c74354... -> 50397711a6a3ba522283...
Size unchanged 162 716.
Kernel-agent restored the trailer on the SCS patch (SCS is no longer
last in the includes ordering — besser#18 is). Cumulative grows
+12 bytes for the restored '-- \n2.54.0\n' sentinel.
b2sum: 0eb091ddaba4... -> ceec602afa85...
Size: 162 704 -> 162 716.
pkgrel=5 = pkgrel=4 + the besser#18 lockdep fix added to the
manifest's includes (in-tree mirror of bes2600-dkms d95453c).
Cumulative b2sum: 334c37b5d37067982bd9... -> 0eb091ddaba4a8f1c3c2a78...
Size: 157 446 -> 162 704 (+5 258 = besser#18 patch with trailer
stripped per the convention now established for the LAST patch in
ka-promote concatenation).
This single pkgrel satisfies all three deliverables of the ohm
migration goal: kernel-agent flow + new marfrit-packages pkg + the
besser#18 fix it contains.
After kernel-agent dropped the wrong git-format-patch trailer from
the SCS xor-neon patch (the trailer was a misdiagnosed fix; the
real problem was the @@ hunk counts).
Cumulative b2sum: ad9e2cb533957f218058... -> 334c37b5d37067982bd9...
Size: 157 458 -> 157 446 (12 byte trailer gone).
Re-promoted after kernel-agent fixed malformed @@ hunk counts in the
SCS xor-neon patch (kernel-agent commit ahead of this on
noether/migrate-pinetab2-pkg-and-patches).
b2sum: bd42cd39106298879eeb... -> ad9e2cb533957f218058...
size unchanged at 157 458.
Drops the f8f3ad9 baseline ("18 commits ahead, BLACK-SCREENS ampere"
per fleet/ampere.yaml bisect note) in favor of the kernel-agent-
managed 10-patch set produced by ka-promote from fleet/ampere.yaml.
Baseline: mainline v7.0-rc3 (3daa4f5dc6cc), plus the 10 scope-tagged

same tip on 2026-05-18 booted ampere via arch_vp9_test extlinux
label):
- VP9 decode bit-exact HW==SW==libva (sha c8624d7c42db66525f53a02a515bc38d0a17ef39f692660cc7bebb1e2d2e1b48)
- AV1 decode bit-exact HW==SW via kdirect (sha 30d2091158d92f3c5e0a807217c3e7307f873267673d92632e7fb147383e7dd1, av1-vpu-dec is mainline 7.0)
prebuild.sh canonical sha256 cleared — gzip-version-dependent, the
script warns-not-fails on mismatch. First successful kafr2 build can
pin a canonical sha here if a reproducibility audit ever needs it.

The n8.1 pin's hwcontext_v4l2request.c deliberately blanks the
transfer-formats list for AV_PIX_FMT_YUV420P10 sw_format (the mapping
target for V4L2_PIX_FMT_NV15), so `ffmpeg -hwaccel v4l2request
-vf hwdownload,format=p010le` on a Hi10P / Main10 input failed at
filter-init with -22 EINVAL — even though kernel-side decode succeeded.
0002-nv15-to-p010-unpack.patch adds an inline NV15→P010 unpack
(5 bytes per 4 samples, little-endian → high-10-of-16) inside
v4l2request_transfer_data_from, exposes AV_PIX_FMT_P010 in
transfer_get_formats for that sw_format, and rejects non-P010
destinations explicitly with ENOSYS instead of silently corrupting
output via av_frame_copy on NV15-packed bytes.
Verified on fresnel (RK3399, linux-fresnel-fourier 7.0-14):
- 5-frame smoke test from issue #21 → exit 0, 13.8MB output
- 20-frame mid-fixture decode → bit-exact HW==SW
sha256 7d9b66d48d8f17b2281da1881c663ecc31722bb218aba1ae23bf28d07aa66b08
- 8-bit baseline (bbb_60s_720p.h264.mp4) still bit-exact HW==SW (no
regression in the existing NV12 path)
- Cross-device repro of original EINVAL on unpatched ampere (RK3588)
pkgrel=4, confirming the bug is upstream-FFmpeg-side, not RK3399-specific
Patch is upstream-able to Kwiboo's v4l2-request-n8.1 branch.
Closes#21.
