NAME
glmark2-drm - OpenGL (ES) 2.0 benchmark suite
SYNOPSIS
glmark2-drm [options]
DESCRIPTION
glmark2-drm is a benchmark for OpenGL (ES) 2.0. It only uses the subset of
the OpenGL 2.0 API that is compatible with OpenGL ES 2.0.
OPTIONS
- -b, --benchmark BENCH
-
A benchmark to run: 'scene(:opt1=val1)*'
(the option can be used multiple times)
- -f, --benchmark-file FILE
-
Load benchmarks to run from a file containing a
list of benchmark descriptions (one per line)
(the option can be used multiple times)
- --validate
-
Run a quick output validation test instead of
running the benchmarks
- --data-path PATH
-
Path to glmark2 models, shaders and textures
- --frame-end METHOD
-
How to end a frame [default,none,swap,finish,readpixels]
- --off-screen
-
Render to an off-screen surface
- --visual-config
-
The visual configuration to use for the rendering target:
'red=R:green=G:blue=B:alpha=A:buffer=BUF'. The parameters may be defined
in any order, and any omitted parameters assume a default value of '1'
- --reuse-context
-
Use a single context for all scenes
(by default, each scene gets its own context)
- -s, --size WxH
-
Size of the output window (default: 800x600)
- --fullscreen
-
Run in fullscreen mode (equivalent to --size -1x-1)
- -l, --list-scenes
-
Display information about the available scenes
and their options
- --show-all-options
-
Show all scene option values used for benchmarks
(only explicitly set options are shown by default)
- --run-forever
-
Run indefinitely, looping from the last benchmark
back to the first
- --annotate
-
Annotate the benchmarks with on-screen information
(same as -b :show-fps=true:title=#info#)
- -d, --debug
-
Display debug messages
- -h, --help
-
Display help
BENCHMARKS
glmark2-drm offers a suite of scenes that can be used to measure many aspects
of OpenGL (ES) 2.0 performance. The way in which each scene is rendered is
configurable through a set of options. To get the available scenes and their
acceptable options you can use the
-l,
--list-scenes command
line option.
In glmark2-drm, a benchmark is defined as a scene plus a set of option values.
You can specify the list and order of the benchmarks to run by using the
-b, --benchmark command line option (possibly multiple times).
If no benchmarks are specified, a default set of benchmarks is used. If a
benchmark option is not specified it assumes its default value (listed with
-l, --list-scenes).
As a special case, a benchmark description string is allowed to not contain a
scene name (i.e. to start with ':'). In this case, any specified option values
are used as the default values for benchmarks following this description
string.
EXAMPLES
To run the default benchmarks:
-
glmark2-drm
To run a benchmark using scene 'shading' with a 'duration' of '5.0' seconds and
'shading' of type 'phong':
-
glmark2-drm -b shading:duration=5.0:shading=phong
To run a series of benchmarks use the -b, --benchmark command
line option multiple times:
-
glmark2-drm -b shading:duration=5.0 -b build:use-vbo=false -b texture
To set default option values for benchmarks:
-
glmark2-drm -b :duration=2.0 -b shading -b build -b :duration=5.0 -b texture
