The patch coverts the man subdir to the standard xorg man page makefile. The version number is automatically updated when a new release is made. The man page section number is no longer hard coded either. The package util-macros at version 1.8 or greater is required.

intel_gpu_top \- Display a top-like summary of Intel GPU usage
|
|
.SH SYNOPSIS

.B intel_gpu_top
|
|
.B intel_gpu_top [ parameters ]
|
|
.SH DESCRIPTION
|
|
.B intel_gpu_top
|
|
is a tool to display usage information of an Intel GPU. It requires root
|
|
privilege to map the graphics device.
|
|
.SS Options
|
|
.TP
|
|
.B -s [samples per second]
|
|
number of samples to acquire per second
|
|
.TP
|
|
.B -o [output file]
|
|
collect usage statistics to [file]. If file is "-", run non-interactively
|
|
and output statistics to stdout.
|
|
.TP
|
|
.B -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.
|
|
.TP
|
|
.B -h
|
|
show usage notes
|
|
.SH EXAMPLES
|
|
.TP
|
|
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.
|
|
.PP
|
|
Note that idle units are not
|
|
displayed, so an entirely idle GPU will only display the ring status and
|
|
header.
|
|
.SH 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.
