# Grant `video` group access to the IPU6 PSYS device and the buffer
# sources libcamera's DmaBufAllocator opens at camera-probe time.
#
# Adapted from kervel/libcamera-ipu6 (debian/99-ipu6-psys.rules).
# PSYS char device. The kernel-side name has changed across versions:
# ipu-psys legacy, <= 6.11
# intel-ipu6-psys current
# intel-ipu7-psys forthcoming
# TAG+="uaccess" grants the active-session user ACL access (same scheme
# logind uses for /dev/video*), so pipewire/wireplumber work without the
# user needing to be in the `video` group, and without depending on the
# user's systemd --user manager having picked up that group at login.

SUBSYSTEM=="intel-ipu7-psys", GROUP="video", MODE="0660", TAG+="uaccess"
# DmaBufAllocator opens these at libcamera enumeration time; PipeWire's
# user service can race ahead of seat ACL application and fail probing.
