PROGRAM:

NAME

glmark2-mir - OpenGL (ES) 2.0 benchmark suite

SYNOPSIS

glmark2-mir [options]

DESCRIPTION

glmark2-mir 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

--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-mir 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-mir, 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-mir

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

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

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

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

To set default option values for benchmarks:

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