GLMARK2-EGL(1)

NAME
glmark2-egl - OpenGL (ES) 2.0 benchmark suite

SYNOPSIS
glmark2-egl [options]

DESCRIPTION
glmark2-egl 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]

--swap-mode MODE
    How to swap a frame, all modes supported only in the DRM flavor, 'fifo' available in all flavors to force vsync [default,immediate,mailbox,fifo]

--off-screen
    Render to an off-screen surface

--visual-config
    The visual configuration to use for the rendering target: 'id=ID:red=R:green=G:blue=B:alpha=A:buffer=BUF:stencil=STENCIL:samples=SAMPLES'. The parameters may be defined in any order, and any omitted parameters assume a default value of '0' (id, stencil, samples) or '1' (red, green, blue, alpha, buffer). If 'id' is set to a non-zero value, all other parameters are ignored

--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)

--results RESULTS
    The types of results to report for each benchmark, as a ':' separated list [fps,cpu,shader]

--results-file RESULTS-FILE
    The file to save the results to, in the format determined by the file extension [csv,xml]

--winsys-options OPTS
    A list of 'opt=value' pairs for window system specific options, separated by ':'

-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

--version
    Display program version

-h, --help
    Display help

BENCHMARKS
glmark2-egl 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-egl, 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-egl

To run a benchmark using scene 'shading' with a 'duration' of '5.0' seconds and
 'shading' of type 'phong':

    glmark2-egl -b shading:duration=5.0:shading=phong

To run a series of benchmarks use the -b, --benchmark command line option multiple times:

    glmark2-egl -b shading:duration=5.0 -b build:use-vbo=false -b texture

To set default option values for benchmarks:

    glmark2-egl -b :duration=2.0 -b shading -b build -b :duration=5.0 -b texture
