glmark2-es2-wayland [options]

glmark2-es2-wayland 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.

-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

glmark2-es2-wayland 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-es2-wayland, 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.

To run the default benchmarks:

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

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

To set default option values for benchmarks:
