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-dkms — DKMS package for the daedalus_v4l2 out-of-tree
|
|
# kernel module (V4L2 stateless decoder shim for Pi 5 / CM5).
|
|
#
|
|
# Pair to daedalus-v4l2 (userspace daemon). When loaded, the module
|
|
# registers /dev/videoNN (V4L2 m2m) + /dev/mediaNN (media controller) +
|
|
# /dev/daedalus-v4l2 (chardev to the userspace daemon). Userspace
|
|
# clients drive the V4L2 m2m + request API path; the daemon does the
|
|
# actual FFmpeg-backed decode on /dev/daedalus-v4l2.
