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.

# 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.
