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
