intel_gpu_top crashes on 16.04

  • 772

When I run intel_gpu_top on my 16.04 system, it crashes at line 145 in intel_mmio.c:

~$ intel_gpu_top

This guy has the same problem.

Is this a bug? How can I fix this?

    Well, this line in the output was key:

    (intel_gpu_top:25862) intel-mmio-CRITICAL: Last errno: 13, Permission denied

    Turns out that you need to run it as root:

    sudo intel_gpu_top

    It would be nice if they printed a "You must be root" message or something to the terminal instead of just crashing.....
