       intel_gpu_top - Display a top-like summary of Intel GPU usage


       intel_gpu_top [ parameters ]


       intel_gpu_top  is  a  tool to display usage information of an Intel GPU.  It requires root
       privilege to map the graphics device.

       -s [samples per second]
              number of samples to acquire per second

       -o [output file]
              collect usage statistics to [file]. If  file  is  "-",  run  non-interactively  and
              output statistics to stdout.

       -e ["command to profile"]
              execute a command, and leave when it is finished. Note that the entire command with
              all parameters should be included as one parameter.

       -h     show usage notes


       intel_gpu_top -o "cairo-trace-gvim.log" -s 100 -e "cairo-perf-trace /tmp/gvim"
              will run cairo-perf-trace  with  /tmp/gvim  trace,  non-interactively,  saving  the
              statistics into cairo-trace-gvim.log file, and collecting 100 samples per second.

       Note that idle units are not displayed, so an entirely idle GPU will only display the ring
       status and header.


       Some GPUs report some units as busy when they aren't, such that even  when  idle  and  not
       hung, it will show up as 100% busy.
