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).

|
* Bump to f0cd29a alongside daedalus-v4l2-dkms. No userspace
|
|
change — the daemon binary in this release is bit-identical to
|
|
the f55b2cd one (the f0cd29a commit only touches kernel/). Bump
|
|
keeps the userspace + DKMS pkgver lockstep so depmod /
|
|
LIBVA_DRIVER_NAME selection stays correct on hosts that
|
|
upgrade.

daedalus-v4l2 (0.1.0+r16+gf55b2cd-1) bookworm trixie; urgency=medium
|
|
|
|
* Initial Debian packaging for the daedalus-v4l2 userspace daemon.
|
|
* Pinned to f55b2cd (Phase 8.13 close): first commit where the full
|
|
ffmpeg -hwaccel vaapi → libva-v4l2-request-fourier → /dev/video0
|
|
→ daemon path lands a pixel-correct decoded NV12 frame back in
|
|
ffmpeg.
|
|
* Codecs: VP9, AV1, H.264 (all via dlopen'd FFmpeg 7.1.3).
|
|
* Capture formats: NV12M (2 plane), NV12 (1 plane, for libva),
|
|
P010 (10-bit single plane).
|
|
* Companion package: daedalus-v4l2-dkms (kernel module).
