GLMARK2-EGL(1)		     General Commands Manual		  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,immedi-
	    ate,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:sam-
	    ples=SAMPLES'.   The parameters may be defined in any order, and any
	    omitted parameters assume a default value of '0' (id, stencil,  sam-
	    ples) 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 ':' sepa-
	    rated 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, sep-
	    arated 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 as-
     pects of OpenGL (ES) 2.0 performance. The way in which each scene	is  ren-
     dered 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 val-
     ues.   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 bench-
     mark 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  de-
     scription 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  tex-
	    ture

     To set default option values for benchmarks:

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