Using the daily focal image (2020-03-30) with identical
raspberrypi/userland everything works "out of the box":
# uname -a
Linux ubuntu 5.4.0-1006-raspi2 #6-Ubuntu SMP Mon Mar 16 13:08:46 UTC 2020
aarch64 aarch64 aarch64 GNU/Linux
# /opt/vc/bin/vcgencmd get_camera
supported=1 detected=1
# /opt/vc
Public bug reported:
On fully upgraded Ubuntu 18.04 aarch64 the vc_sm_cma kernel module does
not expose /dev/vcsm-cma, thus application working with the Raspberry Pi
Camera, e.g. raspivid, do not work properly.
$ lsb_release -a
