I also have a similar problem when trying to open /dev/video0 device inside aarch64 docker container (balena/resin). Although irrelevant, I'm using gstreamer to start a pipeline:
root@5bb9d1759c16:/usr/src/app# gst-launch-1.0 v4l2src device=/dev/video0 ! fakesink
Unsupported ioctl: cmd=0xffffffff80685600
Setting pipeline to PAUSED ...

ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Error getting capabilities for device '/dev/video0': It isn't a v4l2 driver. Check if it is a v4l1 driver.

I have a similar issue, different cmd:
Unsupported ioctl: cmd=0xffffffff8004f50c
Not using docker, just chrooting with qemu-arm-static
in binfmts
, then running fossil open repo.fossil
(fossil-scm).
from qemu-user-static.
For the steps to reproduce the issue, could you share it with the actual commands?
Is the architecture not yet supported ?
At least, the armv7 (ARM 32-bit) CPU architecture emulation is implemented in QEMU, and the binfmt_misc file /proc/sys/fs/binfmt_misc/qemu-arm
is also available.
For example sudo
command works with a specific binfmt_misc flags (credential option). Ref #17 (comment) .
Does your case work with following command?
$ docker run --rm --privileged multiarch/qemu-user-static --reset -p yes -c yes
$ cat /proc/sys/fs/binfmt_misc/qemu-arm
enabled
interpreter /usr/bin/qemu-arm-static
flags: OCF
offset 0
magic 7f454c4601010100000000000000000002002800
mask ffffffffffffff00fffffffffffffffffeffffff
$ docker run something_to_run_arch_container
Some system calls in the container works for only docker run --privileged
option.
Does your case work with x86_64 container on the x86_64 host?
or I need to add ioctl mapping manually?
I do not understand what you are saying, and not familiar with the topic.

Dear @junaruga, thanks for your reply.

I have seen this issues, but still have similar problem for ioctl.
Does your case work with following command?
$ docker run --rm --privileged multiarch/qemu-user-static --reset -p yes -c yes $ cat /proc/sys/fs/binfmt_misc/qemu-arm enabled interpreter /usr/bin/qemu-arm-static flags: OCF offset 0 magic 7f454c4601010100000000000000000002002800 mask ffffffffffffff00fffffffffffffffffeffffff $ docker run something_to_run_arch_container
yes, I have the same result as you.
$ docker run --rm --privileged multiarch/qemu-user-static --reset -p yes -c yes

docker run --privileged
option.
yes, I already have used it.
Does your case work with x86_64 container on the x86_64 host?
yes, I successfully build virtual network interface in others x86_64 container.
or I need to add ioctl mapping manually?
I do not understand what you are saying, and not familiar with the topic.
I apologize for the misunderstanding caused,
I guess it misses some ioctl (system call) implementations.
for example, the following simple steps :
$ docker run --rm --privileged multiarch/qemu-user-static --reset -p yes -c yes
$ docker run --privileged -t -i armv7/armhf-ubuntu /bin/bash
$ apt-get update
$ apt-get install uml-utilities
$ tunctl
Unsupported ioctl: cmd=0x400454ca
TUNSETIFF: Function not implemented
But it can work in x86-64 container.

Thank you for the steps.
By the way, there is a way for multiple lines code syntax in markdown format, if you do not know it.
That is "back quote x 3". The example is here.

Hi, have you solve the issue? i have the same problem. thanks!
