NAME

6       glmark2-drm - OpenGL (ES) 2.0 benchmark suite
7

SYNOPSIS

9       glmark2-drm [options]
10

DESCRIPTION

12       glmark2-drm is a benchmark for OpenGL (ES) 2.0. It only uses the subset
13       of the OpenGL 2.0 API that is compatible with OpenGL ES 2.0.
14

OPTIONS

16       -b, --benchmark BENCH
17              A benchmark to run: 'scene(:opt1=val1)*' (the option can be used
18              multiple times)
19
20       -f, --benchmark-file FILE
21              Load  benchmarks  to run from a file containing a list of bench‐
22              mark descriptions (one per line) (the option can be used  multi‐
23              ple times)
24
25       --validate
26              Run a quick output validation test instead of running the bench‐
27              marks
28
29       --frame-end METHOD
30              How to end a frame [default,none,swap,finish,readpixels]
31
32       --off-screen
33              Render to an off-screen surface
34
35       --visual-config
36              The visual  configuration  to  use  for  the  rendering  target:
37              ´red=R:green=G:blue=B:alpha=A:buffer=BUF'. The parameters may be
38              defined in any  order,  and  any  omitted  parameters  assume  a
39              default value of '1'
40
41       --reuse-context
42              Use a single context for all scenes (by default, each scene gets
43              its own context)
44
45       -s, --size WxH
46              Size of the output window (default: 800x600)
47
48       --fullscreen
49              Run in fullscreen mode (equivalent to --size -1x-1)
50
51       -l, --list-scenes
52              Display information about the available scenes and their options
53
54       --show-all-options
55              Show all scene option values used for benchmarks  (only  explic‐
56              itly set options are shown by default)
57
58       --run-forever
59              Run  indefinitely,  looping  from the last benchmark back to the
60              first
61
62       --annotate
63              Annotate the benchmarks with on-screen information (same  as  -b
64              :show-fps=true:title=#info#)
65
66       -d, --debug
67              Display debug messages
68
69       -h, --help
70              Display help
71

BENCHMARKS

73       glmark2-drm  offers  a suite of scenes that can be used to measure many
74       aspects of OpenGL (ES) 2.0 performance. The way in which each scene  is
75       rendered is configurable through a set of options. To get the available
76       scenes and their acceptable options you can use the  -l,  --list-scenes
77       command line option.
78
79       In  glmark2-drm, a benchmark is defined as a scene plus a set of option
80       values.  You can specify the list and order of the benchmarks to run by
81       using  the  -b,  --benchmark  command  line  option  (possibly multiple
82       times).  If no benchmarks are specified, a default set of benchmarks is
83       used.  If  a  benchmark  option is not specified it assumes its default
84       value (listed with -l, --list-scenes).
85
86       As a special case, a benchmark description string  is  allowed  to  not
87       contain a scene name (i.e. to start with ':'). In this case, any speci‐
88       fied option values are used as the default values for  benchmarks  fol‐
89       lowing this description string.

EXAMPLES

93       To run the default benchmarks:
94
95              glmark2-drm
96
97       To  run  a  benchmark  using scene 'shading' with a 'duration' of '5.0'
98       seconds and
99        'shading' of type 'phong':
100
101              glmark2-drm -b shading:duration=5.0:shading=phong
102
103       To run a series of benchmarks use  the  -b,  --benchmark  command  line
104       option multiple times:
105
106              glmark2-drm  -b  shading:duration=5.0  -b build:use-vbo=false -b
107              texture
108
109       To set default option values for benchmarks:
110
111              glmark2-drm -b :duration=2.0  -b  shading  -b  build  -b  :dura‐
112              tion=5.0 -b texture
