SYNOPSIS
========
**intel_gpu_top** [*OPTIONS*]
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
Number of samples to acquire per second.
-o FILE
Collect usage statistics to FILE. If file is "-", run non-interactively
and output statistics to stdout.
-e COMMAND
Execute COMMAND to profile, 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"
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.
REPORTING BUGS
==============
Report bugs to https://bugs.freedesktop.org.
