Closes part of #60 (firefox-side patch update for fourier2 ffmpeg).
Background: libavcodec61-fourier2 (Kwiboo v4l2-request-n7.1.3 backed)
registers its hwaccels with AV_HWDEVICE_TYPE_V4L2REQUEST (the dedicated
enum added in FFmpeg 7.1+), not AV_HWDEVICE_TYPE_DRM as fourier1 did.
The firefox-fourier patch #3 walked hw_configs looking only for DRM
and fell through to software for every codec.
Patch updates:
- CreateV4L2RequestDeviceContext now takes an int aDeviceType (Mozillas
bundled libavutil headers may lack the V4L2REQUEST enumerator), passed
through to av_hwdevice_ctx_create.
- hw_configs walk accepts DRM (legacy) OR V4L2REQUEST integer value
(13 on Kwibooss no-AMF tree, 14 on upstream-AMF tree).
- Renamed mDRMDeviceContext to mV4L2RequestDeviceContext for accuracy.
Build pkgrel will be bumped at debian-package level to +fourier2.
Upstream PR #3 — kernel per-context vb2_queue lock so concurrent
clients of /dev/video0 don't serialise on a device-wide mutex.
Pi 5 Firefox VAAPI playback (RDD + content + GPU processes each
opening the device) now works without S_FMT EBUSY collisions.
Verified on higgs: YouTube playback engages daedalus at sustained
~230 fps decode through the libavcodec dlopen path, ~7× headroom
over the 30fps@1080p Pi 5 Fourier target.
Both packages: pkgver 0.1.0.r24.f0d4186, pkgrel reset to 1.

this time — following the dual-pin lesson from PR #53.
77f9236 = libva PR #12 merge: src/av1.{c,h} implements av1_set_controls
mapping VAPictureParameterBufferAV1 onto struct v4l2_ctrl_av1_sequence,
queued via S_EXT_CTRLS as V4L2_CID_STATELESS_AV1_SEQUENCE. The
daedalus_v4l2 daemon track will consume the ctrl to synthesise an
OBU_SEQUENCE_HEADER and prepend it to the slice bitstream, so libdav1d
can parse the OUTPUT buffer that ffmpeg-vaapi delivers without the
sequence header.
Until the daemon-side OBU synth lands (issue #11 operator track), the
SEQUENCE ctrl is just sitting in the request unused. Harmless on the
RK3588 vpu981 hardware path (vpu981 parses OBU bytes directly, ignores
the ctrl payload).

Upstream PR #2 landed the one-line kernel fix that was the missing
half of issue libva-v4l2-request-fourier#8: device_run now calls
v4l2_ctrl_request_setup() before reading ctrl->p_cur, so the
daedalus_h264_meta the daemon receives reflects the in-flight
media_request's bound H.264 stateless control values instead of
stale/default ones.
Pairs with libva-v4l2-request-fourier 1.0.0+r382+gc1bb444 (max_num_
ref_frames fallback + Fix 4 instrumentation that exposed the
control-binding gap in the first place).
Effect on Pi 5 / CM5 hosts (higgs): ffmpeg -hwaccel vaapi against
H.264 sources now produces actual decoded content (per-frame
fnv1a hashes differ, zero MB-decode errors) instead of the
constant 0x6a6a05c5 "best-effort give-up" hash and cascading
decode warnings.
Both packages: pkgver 0.1.0.r22.462aa4b, pkgrel reset to 1.

Bumps the libva backend pin to include marfrit/libva-v4l2-request-fourier
PR #9 — h264_set_controls fix for the bitstream-vs-session value drift
that breaks the daedalus_v4l2 strict-consumer path (issue #8):
* max_num_ref_frames fallback when VAAPI client left it 0 (count
valid DPB entries, then per-profile spec minimum)
* one-line request_log at h264_set_controls entry dumping raw
VAAPI bitfields for disambiguating remaining PPS-flag-zero
portion of #8
The PR explicitly defers the deeper "profile_idc / level_idc from
bitstream" portion of #8 — VAAPI's VAPictureParameterBufferH264 omits
both fields, so a real fix needs SPS-NAL parsing or daedalus
wire-protocol pass-through. Not in this bump.

iter12 hit a wall: Brave's ANGLE-Vulkan path requires GLES3, which
requires VK_EXT_transform_feedback, which PanVk-Bifrost did not
implement. This iter implements that extension, unlocking the full
ANGLE-Vulkan-on-Bifrost stack.
The implementation follows Panfrost-Gallium's well-validated XFB lowering
(nir_io_add_intrinsic_xfb_info + pan_nir_lower_xfb) wired into the PanVk
shader pipeline after nir_lower_io. Adds 4 XFB buffer address sysvals
plus per-draw num_vertices to the graphics sysval struct. Buffer state
is tracked on the cmd buffer; per-draw sysval upload populates either
the bound buffer's GPU address or PAN_SHADER_OOB_ADDRESS (memory-sink)
so XFB-capable pipelines used outside Begin/End survive without GPU
fault — the Panfrost-Gallium idiom from gallium/drivers/panfrost/
pan_cmdstream.c:1350.
Verified on PineTab2 (Mali-G52 r1 MC1, RK3566):
- /tmp/panvk-iter13/probe_xfb: 3 vertices captured byte-exact
- /tmp/panvk-iter13/probe_xfb_nodraw: XFB pipeline used without Bind/
Begin/End survives — DEVICE_LOST regression closed
- Brave 148 with --use-angle=vulkan: WebGL 2.0 (OpenGL ES 3.0) creates
cleanly, renderer reports
"ANGLE (ARM, Vulkan 1.2.335 (Mali-G52 r1 MC1), panvk)"

pkgver bumped 26.0.6.r2 -> 26.0.6.r3; iter13 patch applied via

Upstream PR #1 landed daemon-side synthesis of H.264 SPS/PPS NAL
units from the V4L2 stateless control structs. This bumps the
package pin so both the userspace daemon and the kernel module
pick up the change in lockstep (wire protocol grew a new
DAEDALUS_REQ_FLAG_H264_META bit + struct daedalus_h264_meta —
kernel and daemon MUST match).
Effect on Pi 5 / CM5 hosts (higgs): ffmpeg -hwaccel vaapi against
H.264 sources will actually decode through the daedalus daemon
instead of failing with "non-existing PPS 0 referenced".
Both arch + debian packages: pkgver 0.1.0.r20.3dd0eb0 (count from
git rev-list), pkgrel reset to 1 (new upstream pin).
VP9 / AV1 paths unchanged.

Follow-up to libva PR #7 (merged as 9898331). Without that commit,
H.264/VP9/AV1 profiles never got advertised on Pi 5 mixed deploys
(rpi-hevc-dec primary + daedalus_v4l2 alt) because the profile-
enumeration probe in any_fd_supports_output_format only walked
rkvdec / hantro / rpi-hevc-dec / vpu981 fds. ffmpeg vaapi -i
h264_test.mp4 on higgs bailed with "No support for codec h264
profile 578" before the LIBVA-1 per-codec dispatch could even fire.
9898331 extends the fds[] from 5 to 6 with video_fd_daedalus as
the 6th slot (HAVE_DAEDALUS_V4L2-gated, -1 fallback otherwise).
Effect on higgs once this lands: vainfo lists VP9Profile0 +
AV1Profile0 + H264* alongside HEVCMain, and ffmpeg -hwaccel vaapi
-i h264_test.mp4 routes through the daedalus daemon (via 'd' kind
in request_switch_device_for_profile).
Both packages: pkgver 1.0.0.r380.9898331 (count from rev-list),
pkgrel reset to 1 (new upstream pin). Backward-compatible on
RK3399/3588 — the new fd slot is gated by HAVE_DAEDALUS_V4L2 *and*
video_fd_daedalus >= 0, both false in those deployments.
Companion to the prior LIBVA-{1,ABI} bumps that landed in marfrit-
packages PRs #43, #44. Together they close the Pi 5 stack: boot ->
modules-load.d loads daedalus_v4l2 -> daedalus-v4l2.service starts
daemon -> libva opens both decoders -> ffmpeg -hwaccel vaapi
enumerates all codecs from both -> routes per-codec.

Bumps both Arch (PKGBUILD) and Debian (build-deb.sh + changelog)

Effect: Pi 5 / CM5 mixed deployment (higgs) now opens BOTH
rpi-hevc-dec and daedalus_v4l2 from one libva session and routes
per-codec — HEVC to rpi-hevc-dec ('p'), VP9 / AV1 / H.264 to the
daedalus daemon (new 'd' kind). Before c332d34, find_codec_device
picked rpi-hevc-dec by known_decoder_drivers[] order and the
daedalus slot stayed -1, so VP9/AV1/H.264 frames failed S_FMT.
Also closes a small fd leak in RequestTerminate (daedalus pair —
caught while reviewing the alt-driver expansion).
Both packages: pkgver bumped 1.0.0.r378.c332d34, pkgrel reset to 1
(new upstream pin). Backward-compatible on RK3399/3588 — new
branches gated by HAVE_DAEDALUS_V4L2 *and* video_fd_daedalus >= 0,
both false in those deployments.
Companion: daedalus-v4l2{,-dkms} bump 481279c landed in PR #39
(systemd unit + auto-enable). Together they close the Pi 5 stack:

starts daemon → libva opens both decoders → ffmpeg -hwaccel vaapi

Installed systems carry 1:1.0.0.r361.cf8cd9d-1 from an earlier build
that had epoch=1. Current PKGBUILD ships 1.0.0.r376.de27e95-1 without

ohm refuses to upgrade with:

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:

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

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 —

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).

functional equivalence verified: wlan0 associates,

Per-fix revertability now real: removing an include from

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).
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.

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.

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.

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.

-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.

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.
Single-bit fix via git update-index --chmod=+x. No content change.
Sibling to kernel-agent PR #8 which lands the scope-tagged board
patches + fleet/ampere.yaml manifest. This PR carries the
makepkg-side recipe.
## 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 Sebastian Reichel (Rock 5 ITX hdmirx — unused by ampere)
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.
## Out of scope this PR
- Ask 2 (VP9 enablement) and Ask 3 (AV1 dec) from kernel-agent issue #6
- Build + publish + install (sequenced after this PR + kernel-agent PR #8 merge)
- 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.
Triggered by 'pacman -Syu' on fresnel showing local 1:6.11.0-2 newer
than (then-)extra 6.11.0-4. By the time of this commit Arch has moved
on to 6.11.1-1; rebase straight to that.
Diff against Arch's qt6-base 6.11.1 PKGBUILD reduced:
- _pkgver 6.11.0 -> 6.11.1
- pkgrel 3 -> 1 (reset on pkgver bump)
- sha256 of git tag updated to 2eafe504... (matches Arch's 6.11.1 PKGBUILD)
- Drop cherry-pick of 8b54513cdcf6 (qdbus crash fix landed upstream
in 6.11.1; Arch dropped it from theirs as well)
- depends: gcc-libs replaced by libgcc + libstdc++ (Arch split these
into separate packages between 6.11.0 and 6.11.1)
- Build flag: -DFEATURE_sql_ibase=OFF removed, -DFEATURE_mimetype_database=OFF
added (Arch toggled in 6.11.1)
Kept (the reason this fork exists):
- 0001/0002/0003 GL_R8-on-ES3 patches (Mali GLES3 KWin compositor stall fix)
- qt6-base-cflags.patch + qt6-base-nostrip.patch (system CFLAGS + skip strip)
- qt6-xcb-private-headers-fourier sub-package (depended on by other fork pkgs)
- epoch=1 (precedence guarantee until upstream lands GL_R8/ES3 fix)
Patches NOT dry-run-verified against 6.11.1 source (qt clone is multi-GB
and impractical to fetch for a quick check). They touch glyph cache and
RHI gles2 paths that have been stable since Qt 6.10; expected to apply
cleanly. Will revert pkgrel and re-pin if first build hits hunk failures.
Triggered by 'pacman -Syu' on fresnel showing local 1:6.6.4-1 newer
than extra 6.6.5-1 (epoch wins, but our base lags upstream).
- pkgver 6.6.4 -> 6.6.5
- pkgrel 3 -> 1 (reset on pkgver bump)
- sha256sum updated for new tarball
- 0001-transaction-bypass-watchDmaBuf-fence-wait.patch dry-run verified
clean against 6.6.5/src/wayland/transaction.cpp
Epoch=1 retained until upstream lands a proper V4L2 implicit-sync
fence-wait bypass (the patch-header hypothesis is still being tested
through ohm/fresnel HW-decode validation; not upstreamable yet).
