Upstream PR #3 — kernel per-context vb2_queue lock so concurrent clients of /dev/video0 don't serialise on a device-wide mutex. Pi 5 Firefox VAAPI playback (RDD + content + GPU processes each opening the device) now works without S_FMT EBUSY collisions. Verified on higgs: YouTube playback engages daedalus at sustained ~230 fps decode through the libavcodec dlopen path, ~7× headroom over the 30fps@1080p Pi 5 Fourier target. Both packages: pkgver 0.1.0.r24.f0d4186, pkgrel reset to 1. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

daedalus-v4l2 (0.1.0+r24+gf0d4186-1) bookworm trixie; urgency=medium
|
|
|
|
* Bump to f0d4186 — kernel per-ctx vb2 lock fix. daedalus_queue_init
|
|
was wiring src_vq->lock and dst_vq->lock to ctx->dev->m2m_lock (a
|
|
device-wide mutex), serialising every vb2 ioctl across all
|
|
concurrent clients of /dev/video0. For Firefox (which spawns
|
|
separate content + RDD + GPU processes that each open the device
|
|
and run libva probe simultaneously), one libva session's
|
|
S_FMT(OUTPUT_MPLANE) hit EBUSY while another was mid-streamon —
|
|
Firefox VAAPI playback fell apart at startup.
|
|
* Fix gives each open() its own ctx->vb_mutex; vb2 ioctls run
|
|
independently per client. Matches cedrus / rkvdec / hantro
|
|
pattern.
|
|
* Verified on higgs: Firefox YouTube playback engages VAAPI cleanly,
|
|
sustained ~230 fps decode at 640x368 through the daedalus daemon,
|
|
zero EBUSY in stderr or daemon journal.

daedalus-v4l2 (0.1.0+r22+g462aa4b-1) bookworm trixie; urgency=medium
|
|
|
|
* Bump to 462aa4b — kernel-side fix for control-binding gap that
|
|
closes the libva→daemon SPS/PPS pipeline. Kernel device_run now
|
|
calls v4l2_ctrl_request_setup() before reading ctrl->p_cur, so
|
|
the daemon's daedalus_h264_meta block actually carries THIS
|
|
request's V4L2 stateless H.264 control values instead of stale
|
|
/default ones. Pairs with libva-v4l2-request-fourier r382+gc1bb444
|
|
(Fix 3 + Fix 4 from issue libva-v4l2-request-fourier#8).
|
|
* After-fix on higgs (Pi CM5): ffmpeg -hwaccel vaapi -i h264.mp4
|
|
produces unique decoded P-frames (per-frame fnv1a hashes differ)
|
|
and zero "error while decoding MB" / "reference frames exceeds
|
|
max" warnings.

daedalus-v4l2 (0.1.0+r20+g3dd0eb0-1) bookworm trixie; urgency=medium
|
|
|
|
* Bump to 3dd0eb0 — DAEMON-PPS H.264 SPS/PPS NAL synthesiser.
|
|
Daemon now reconstructs AnnexB SPS+PPS NAL units from the V4L2
|
|
stateless H.264 control structs (forwarded by the kernel via
|
|
a new struct daedalus_h264_meta block in REQ_DECODE) and
|
|
prepends them to the slice bitstream before feeding libavcodec.
|
|
Without this, ffmpeg -hwaccel vaapi on H.264 sources failed
|
|
with "non-existing PPS 0 referenced" even after LIBVA-1/-2
|
|
routing correctly delivered the request.
|
|
* Wire protocol: new DAEDALUS_REQ_FLAG_H264_META bit + struct
|
|
daedalus_h264_meta; daemon and kernel must be installed in
|
|
lockstep (this package + daedalus-v4l2-dkms 0.1.0+r20+g3dd0eb0).
|
|
* VP9 / AV1 paths unchanged.

daedalus-v4l2 (0.1.0+r18+g481279c-1) bookworm trixie; urgency=medium
|
|
|
|
* Bump to 481279c. Upstream landed the systemd unit + modules-load.d
|
|
drop-in (packaging/systemd/daedalus-v4l2.{service,modules-load}).
|
|
* Package now ships /lib/systemd/system/daedalus-v4l2.service and
|
|
/usr/lib/modules-load.d/daedalus-v4l2.conf.
|
|
* postinst: daemon-reload, enable the service, trigger
|
|
systemd-modules-load, and start if /dev/daedalus-v4l2 is already
|
|
present. Operator no longer needs to remember the modprobe +
|
|
systemctl-enable dance after install.
|
|
* prerm/postrm: stop + disable + daemon-reload.

daedalus-v4l2 (0.1.0+r17+gf0cd29a-1) bookworm trixie; urgency=medium
|
|
|
|
* 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).
