Getting ZE_RESULT_ERROR_DEPENDENCY_UNAVAILABLE when running application inside a docker container

[saratpoluri]

Docker container image: Ubuntu 20.04.4

Host: Ubuntu 20.04.4, Kernel 5.10.65

Steps to reproduce: docker -it -rm --device /dev/dri Follow instructions here to install the latest compute-runtime packages: https://dgpu-docs.intel.com/installation-guides/ubuntu/ubuntu-focal.html

Clone this level-zero repo, built the zello_world sample.

When zello_world is run, it throws the following error: terminate called after throwing an instance of 'std::runtime_error' what(): Unknown ze_result_t value: 1879179264 Aborted (core dumped)

Which is 0x70020000 i.e ZE_RESULT_ERROR_DEPENDENCY_UNAVAILABLE

After doing gdb, found that the ze_init function fails after calling ze_lib::context->Init and returns the above error code.

Please help me address this issue. Only discrepancy I find in my container is the gid of the /dev/dri/renderD128 file is 'ssh' instead of 'render' in the host OS.

Hi, ZE_RESULT_ERROR_DEPENDENCY_UNAVAILABLE is not returned from level zero loader. This is coming from compute-runtime. Can you please move your question to compute-runtime repo?

Please help me address this issue. Only discrepancy I find in my container is the gid of the /dev/dri/renderD128 file is 'ssh' instead of 'render' in the host OS.

By default, container runtime takes containerized device access rights from the host, but your container's /etc/group file just does not seem to match the group IDs on the host. In general, you should be checking the numerical IDs, not the "user-friendly" names tools map them to based on (potentially mismatching) /etc/ files in the container.

And to access (write to / communicate with) the GPU device, the container process obviously needs to be a user that does have that access. Either use root, a matching (numerical) user ID or matching (numerical) group ID.
