intel_reg.rst was the first man page written in reStructuredText. Follow suit with the rest of the man pages. Add a generated defs.rst include file for definitions such as intel-gpu-tools version. This replaces the MAN_SUBSTS sed script substitutions from xorg-macros for old man pages. Signed-off-by: Jani Nikula <jani.nikula@intel.com>

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.
