NAME
intel_gpu_top - Display a top-like summary of Intel GPU usage
SYNOPSIS
intel_gpu_top
intel_gpu_top [ parameters ]
DESCRIPTION
intel_gpu_top is a tool to display usage information of an Intel GPU. It requires root privilege to map
the graphics device.
Options
-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
EXAMPLES
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.
BUGS
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.
