Check/mention permissions in initialization error message

[rashidrafeek]

I am using a hardware which seems to be supported (Processor with code name Coffee Lake):

julia> versioninfo()
Julia Version 1.7.2
Commit bf53498635 (2022-02-06 15:21 UTC)
Platform Info:
  OS: Linux (x86_64-pc-linux-gnu)
  CPU: Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-12.0.1 (ORCJIT, skylake)
Environment:
  JULIA_NUM_THREADS = 4
  JULIA_NUM_PRECOMPILE_TASKS = 8

But I am getting the following error while trying to use oneAPI:

julia> using oneAPI
┌ Error: No compatible oneAPI driver implementation found.

The problem is that the error thrown by oneAPI here can actually be caused by a variety of reasons. One can be that you don't have the necessary permissions to access the device nodes in /dev/dri*. Could you verify that? If that's the case, can you strace Julia doing using oneAPI and post that log?

Thanks for the info. I tried the same and it was a permission issue as you suggest. The issue was solved by adding myself to the video group following the instruction here.

Would it be good to modify the error message to account for this case? If you feel its not worth it, feel free to close this issue.

Yes, we should probably include that in the error message; I'll leave this issue open until we do.
