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 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.
