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.

Description: V4L2 stateless decoder shim kernel module (DKMS) — Pi 5 / CM5
|
|
Out-of-tree V4L2 m2m kernel module for the daedalus-v4l2 stack on
|
|
Raspberry Pi 5 / CM5. Registers /dev/videoNN (V4L2 stateless m2m
|
|
decoder), /dev/mediaNN (media controller with request API), and
|
|
/dev/daedalus-v4l2 (chardev bridge to the userspace daemon).
|
|
.
|
|
The actual decode happens in the userspace daemon shipped by the
|
|
daedalus-v4l2 package — this module is just the kernel-side V4L2
|
|
plumbing. Install both to actually serve VAAPI / V4L2 clients.
|
|
.
|
|
Built via DKMS against the running kernel's headers.
