NAME

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

SYNOPSIS

       intel_gpu_top [OPTIONS]

DESCRIPTION

       intel_gpu_top is a tool to display usage information on Intel GPU's.

       The  tool  gathers  data using perf performance counters (PMU) exposed by i915 and other platform drivers
       like RAPL (power) and Uncore IMC (memory bandwidth).

OPTIONS

       -h     Show help text.

       -J     Output JSON formatted data.

       -l     List plain text data.

       -o <filepath|->
              Output to the specified file instead of standard output.  '-' can also be specified to  explicitly
              select standard output.

       -s <ms>
              Refresh period in milliseconds.

LIMITATIONS

       • Not  all  metrics  are  supported  on  all  platforms. Where a metric is unsupported it's value will be
         replaced by a dashed line.

       • Non-root access to perf counters is controlled by the perf_event_paranoid sysctl.
