Lock-step bump of both packages to daedalus-v4l2#7 + #4. PROTO_VERSION bumps 0 → 1 at the daemon ↔ kernel chardev wire: REQ_DECODE adds __u64 src_pts (the OUTPUT vb2 timestamp); RESP_FRAME adds __u32 flags (HAS_PIXELS / SRC_CONSUMED) + __u64 output_src_pts (= frame->pts on drain). Both .debs must be installed atomically or the chardev handshake rejects the version mismatch. * daedalus-v4l2: daemon's send_packet → receive_frame loop now stamps pkt->pts = req->src_pts and looks up the cookie for each drained frame via frame->pts. chardev_client emits multiple RESP_FRAME messages per REQ_DECODE when libavcodec's display- order DPB releases an earlier frame on receipt of a later bitstream — fixes the "2 1 4 3 6 5" pair-swap on H.264 streams with B-frames. * daedalus-v4l2-dkms: kernel device_run mirrors src_buf timestamp into REQ_DECODE.src_pts. Completion path splits HAS_PIXELS / SRC_CONSUMED: src is released as soon as send_packet succeeds (so the m2m scheduler moves on), dst stays parked until the matching frame is drained later. TIMESTAMP_COPY's auto src→dst pairing no longer applies once lifecycles decouple — dst is stamped explicitly from inflight->src_pts at HAS_PIXELS time. * daedalus-v4l2-dkms also carries forward the -2 multi-kernel postinst fix (#64) from the prior PKGREL. PKGREL resets to 1 on the new upstream pin. The daedalus-v4l2#4 H.264 DECODE_MODE + START_CODE menu controls (a cosmetic warning fix that PR landed alongside #7) is also subsumed — "Unable to set control(s) error_idx=2/2" no longer fires.

# Build daedalus-v4l2-dkms_<ver>_all.deb (kernel module via DKMS).
|
|
#
|
|
# Installs kernel/ source tree to /usr/src/daedalus_v4l2-${PKGVER}/
|
|
# plus a dkms.conf. Postinst registers with DKMS (dkms add + build +
|
|
# install). Prerm deregisters. Result: the daedalus_v4l2 module
|
|
# auto-rebuilds against any installed kernel headers without users
|
|
# needing to remember to dkms-add it.
|
|
#
|
|
# Architecture: all. The kernel module itself is per-kernel-version,
|
|
# but the SOURCE package is arch-independent.

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.
