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).

# daedalus-v4l2 — userspace daemon + V4L2 m2m test tools.
|
||
#
|
||
# Pair to daedalus-v4l2-dkms (kernel module). Together they expose
|
||
# /dev/videoNN + /dev/mediaNN as a V4L2 stateless decoder shim on Pi 5 /
|
||
# CM5, decoding VP9 / AV1 / H.264 via dlopen'd FFmpeg in a single-
|
||
# threaded daemon and shipping decoded NV12 / P010 back through dmabuf.
|
||
# Consumed end-to-end by libva-v4l2-request-fourier (>= 1.0.0.r376) so
|
||
# `ffmpeg -hwaccel vaapi` against vp9_small.ivf produces byte-exact NV12.
