`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.

Mirror of arch/ffmpeg-v4l2-request-fourier into the Debian tree.
Same source pin (Kwiboo v4l2-request-n8.1 @ b57fbbe), same 2
patches (libudev-bypass-fallback + nv15-to-p010-unpack), same

that drive rkvdec / hantro / cedrus / rpi-hevc-dec /
daedalus_v4l2 stateless decoders through libavcodec's hwdevice
DRM path, bypassing libva. Required by mpv-fourier and
firefox-fourier as their backing FFmpeg; also the kdirect
bit-exact reference for libva-v4l2-request-fourier validation.
NOT strictly required for the VAAPI-only path on

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.

Mirror of arch/daedalus-v4l2-dkms into the Debian tree.
Architecture: all (source package — DKMS rebuilds per-kernel
at install time). Same pin (f04d700, Phase 8.13 close).
Installs kernel/ source to /usr/src/daedalus_v4l2-<ver>/ with
generated dkms.conf. postinst runs `dkms add` + `dkms
autoinstall` so the module builds against the running kernel's
headers automatically. prerm runs `dkms remove --all`.
Same Makefile-include-path flattening as the Arch sibling:
copies daedalus_v4l2_proto.h into kernel/include/ and patches
the Makefile's -I path.

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
patches under marfrit/kernel-agent/patches/{soc,module,board,driver}/:
- 1 soc/rk3588 pwm15 pinctrl
- 6 board/coolpi-cm5-genbook DTS patches
- 3 driver/media Sarma VP9-on-VDPU381 patches (PR #24 closure)
New _commit 48a8c78 reflects this tree state in ~/src/linux-rockchip
(branch vp9-build on ampere, exactly v7.0-rc3 + 10 manifest patches).
End-to-end verified before this iteration was cut (hand-build of the
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.
Cross-references:
- marfrit/kernel-agent#12 (VP9 enablement closure)
- marfrit/kernel-agent PR #24 (Sarma patch import + ampere.yaml bump)
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.
Tracks upstream lmcp v1.1.1 (commit 9707f7a). Single-bug-fix
release: lmcp:tool() now normalises empty inputSchema.properties
by dropping the key, so Zod-strict MCP clients don't reject
tools/list with "expected: record, received: array".
Discovered live on a hertz-tools deployment where two custom
no-arg tools tripped the check and caused Claude Code to mark
the endpoint as disconnected.

PKGBUILD already renamed itself (pkgname=ffmpeg-v4l2-request-fourier,
replaces=(ffmpeg ffmpeg-v4l2-request-git)) but the containing
directory was never moved. This commit completes the rename to align
the path with the package identity and the rest of the -fourier
umbrella (libva, mpv, kwin, qt6-base, chromium, linux-*).
CI workflow path-trigger is wildcard (arch/**), unaffected. Step
names + cp source path updated to the new directory.
Predecessor experimental package (tarball + 18 stacked patches) is
superseded by libva-v4l2-request-fourier (git-tracked fork tip,
iter38 multi-device probe). The successor already declares
replaces=('libva-v4l2-request-ohm-gl-fix') so installs migrate
automatically; this commit just makes the deprecation visible in
README + pkgdesc.
Kept in-tree as historical reference for the ohm_gl_fix Phase 6
audit trail.
CI binary segfaulted on HEVC vaEndPicture even though
/etc/makepkg.conf has OPTIONS=(... !lto ...). Root cause: arch-meson's
wrapper hard-codes `-D b_lto=true` regardless of makepkg.conf, so
the binary still gets cross-function ICF (Identical Code Folding)
under -O2 + LTO.
HEVC is the only codec in the campaign that submits a per-frame chain
of 4 control structs (SPS + PPS + DECODE_PARAMS + SLICE_PARAMS); ICF
finds a near-duplicate per-codec helper across the codec dispatch and
merges them, then the wrong instance's local stack layout is invoked
on the HEVC path → SEGV. The other 4 codecs (H.264, VP8, VP9, MPEG-2)
submit fewer/simpler control structs and tolerate the folding by
accident.
Empirical confirmation from the issue body's binary bisection:
meson build (default debugoptimized) 485 KB HEVC ✓
arch-meson + --buildtype=release 145 KB HEVC ✓
arch-meson + release + -flto 76 KB HEVC SEGV
CI build (this package, 7ac934e-1) 133 KB HEVC SEGV
Fix: append `-Db_lto=false` to the arch-meson invocation.
pkgrel 1 -> 2.
The exec bit was missing on prebuild.sh as committed in PR #15
(it landed mode 0644). Running './prebuild.sh' fails with
'Permission denied'; bash ./prebuild.sh works as a workaround but
the shebang is intended to do its job.
Caught while running the first linux-ampere-fourier build on
boltzmann today. README.md examples show './prebuild.sh' so users
will hit the same error.

## Baseline
marfrit/linux-rk3588-marfrit @ f8f3ad9 (mainline v7.0-rc3 + 18 commits):
10 by Markus Fritsche (board DTS + Kconfig + suspend/wakeup + bt)
4 by Shawn Lin (phy: rockchip-snps-pcie3 stability)
2 by Cristian Ciocaltea (clk + dw-dp bridge — Collabora)

1 by Pedro Alves (CLK_SET_RATE_PARENT VOP2 fix)
The 6 board-relevant patches (pwm15 pinctrl + RK806 power-off +
genbook pwm-fan/speaker/USB-C/lid) are scope-tagged in
kernel-agent. The 12 others are 'cherry-picks-in-baseline'
currently — splitting them into scope-tagged patches is a
follow-up.
## Source distribution
The kernel tree isn't pushable to Gitea (boltzmann's working clone
is shallow). Tarball (260MB) doesn't belong in marfrit-packages
either. Pragmatic shortcut: ship prebuild.sh that produces the
tarball locally from $LINUX_RK3588_MARFRIT_TREE (default
~/src/linux-rockchip) just before makepkg runs. PKGBUILD source
array references the tarball by name; makepkg picks it up from
the PKGBUILD dir.
Build flow:
cd arch/linux-ampere-fourier
./prebuild.sh # produces 260MB tarball; idempotent w/ sha check
makepkg -s --noconfirm
Future iteration: host the tarball on Gitea release assets or
packages.reauktion.de/sources/ and switch source to URL.
## What the PR ships
PKGBUILD — the recipe (linux-rk3588-marfrit @ f8f3ad9)
config — snapshot of ampere's /proc/config.gz
linux-ampere-fourier.preset — mkinitcpio preset, /boot/firmware/ paths
extlinux-add.hook — alpm hook, fires on /boot/firmware/Image* changes
extlinux-add.sh — idempotent managed-label injector for
/boot/firmware/extlinux/extlinux.conf
(vfat on mmcblk0p1, ampere-specific path)
prebuild.sh — source-staging helper (see above)
README.md — build + install runbook
## ampere-specific boot path differences vs fresnel
ampere boots from /boot/firmware/ (vfat partition), not /boot/ (root
partition) like fresnel. The PKGBUILD installs Image + initramfs + DTB
under /boot/firmware/ directly. The extlinux-add hook fires on
/boot/firmware/<X> path changes and edits
/boot/firmware/extlinux/extlinux.conf. The mkinitcpio preset writes
initramfs to /boot/firmware/.
Only one PRESET ('default') — no fallback image — because
/boot/firmware is ~1G total and two ~20MB initramfs files plus the
DTB and a couple of kernel-image backups would squeeze it tight.

- Splitting the 12 non-board commits into scope-tagged kernel-agent patches
Sibling to kernel-agent PR #7 (which lands the vb2_dma_resv RFC v2
series under patches/subsystem/media/videobuf2/ and updates
fleet/fresnel.yaml to include them). This PR carries the same three
patches in the build-tree-ready form for the linux-fresnel-fourier
PKGBUILD.
Background: Markus iterated v2 locally on boltzmann reaching pkgrel=14
since the 2026-05-09 bootstrap published 7.0-1. v2 attaches the V4L2
producer fence at device_run in slept-OK context per Dufresne's v1
review on linux-media. Drivers opted in here: hantro + rockchip-rga.
Changes:
- pkgrel 1 -> 14
- pkgdesc adds '+ vb2_dma_resv RFC v2'
- source array gains 3 new local patch files (scope-tagged comments
point to where they live in marfrit/kernel-agent)
- sha256sums extended to 11 SKIP entries
No prepare() edit needed — the existing for-loop applies every *.patch
in $srcdir, so the 4/5/6 patches get picked up automatically. config
unchanged (verified diff vs boltzmann's local pkgrel=14 tree).
Pre-built artifacts: linux-fresnel-fourier-7.0-14-aarch64.pkg.tar.zst
and linux-fresnel-fourier-headers-7.0-14-aarch64.pkg.tar.zst already
exist on boltzmann at /home/mfritsche/src/kernel-agent-bootstrap/
build/marfrit-packages/arch/linux-fresnel-fourier/ — will be signed
and published via marfrit-publish-arch after this PR merges (no fresh
compile needed; the artifacts were built locally during the iteration
loop that reached pkgrel=14).
Empirical follow-up to #9. After packaging 150.0.1-4 and installing on
fresnel, MOZ_LOG showed the failure pattern was still present:
D/FFmpegVideo FFMPEG: Using preferred software codec h264
No VAAPI_VLD engagement, no dmabuf surface locking — Gecko bailed
before reaching the patched VAAPI path. Same symptom as issue #8
pre-fix, despite the prefs file being on disk at the expected path.
Root cause: /usr/lib/firefox-fourier/browser/defaults/preferences/ is
NOT a vendor-prefs scan location in Firefox 150. Mozilla's canonical
scan dir is /usr/lib/<app>/defaults/preferences/ — without the
'browser/' prefix.
Verified by hand-copying the same file to /usr/lib/firefox-fourier/
defaults/preferences/ and re-running the H.264 playback test:
D/FFmpegVideo FFMPEG: Requesting pixel format VAAPI_VLD
D/Dmabuf VideoFrameSurface: VAAPI locking dmabuf surface UID 26267
FFMPEG ID 0x4000000 mAVHWFrameContext ...
D/Dmabuf VideoFrameSurface: VAAPI locking dmabuf surface UID 26268
FFMPEG ID 0x4000001 ...
(15+ surface locks)
End-to-end zero-copy DMABUF path engaged, hantro/rkvdec dekodes the
H.264 stream via libva-v4l2-request-fourier iter38b.
pkgrel 4 -> 5. No other PKGBUILD changes.
