NAME

6       glmark2-es2-wayland - OpenGL (ES) 2.0 benchmark suite
7

SYNOPSIS

9       glmark2-es2-wayland [options]
10

DESCRIPTION

12       glmark2-es2-wayland  is  a  benchmark for OpenGL (ES) 2.0. It only uses
13       the subset 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       --data-path PATH
30              Path to glmark2 models, shaders and textures
31
32       --frame-end METHOD
33              How to end a frame [default,none,swap,finish,readpixels]
34
35       --swap-mode MODE
36              How to swap a frame, all modes supported only in the DRM flavor,
37              'fifo'  available in all flavors to force vsync [default,immedi‐
38              ate,mailbox,fifo]
39
40       --off-screen
41              Render to an off-screen surface
42
43       --visual-config
44              The visual  configuration  to  use  for  the  rendering  target:
45              ´id=ID:red=R:green=G:blue=B:alpha=A:buffer=BUF:stencil=STEN‐
46              CIL:samples=SAMPLES'.  The parameters may be defined in any  or‐
47              der,  and  any  omitted parameters assume a default value of '0'
48              (id, stencil, samples) or '1' (red, green, blue, alpha, buffer).
49              If 'id' is set to a non-zero value, all other parameters are ig‐
50              nored
51
52       --reuse-context
53              Use a single context for all scenes (by default, each scene gets
54              its own context)
55
56       -s, --size WxH
57              Size of the output window (default: 800x600)
58
59       --fullscreen
60              Run in fullscreen mode (equivalent to --size -1x-1)
61
62       --results RESULTS
63              The types of results to report for each benchmark, as a ':' sep‐
64              arated list [fps,cpu,shader]
65
66       --results-file RESULTS-FILE
67              The file to save the results to, in the format determined by the
68              file extension [csv,xml]
69
70       --winsys-options OPTS
71              A  list of 'opt=value' pairs for window system specific options,
72              separated by ':'
73
74       -l, --list-scenes
75              Display information about the available scenes and their options
76
77       --show-all-options
78              Show all scene option values used for benchmarks  (only  explic‐
79              itly set options are shown by default)
80
81       --run-forever
82              Run  indefinitely,  looping  from the last benchmark back to the
83              first
84
85       --annotate
86              Annotate the benchmarks with on-screen information (same  as  -b
87              :show-fps=true:title=#info#)
88
89       -d, --debug
90              Display debug messages
91
92       --version
93              Display program version
94

BENCHMARKS

99       glmark2-es2-wayland  offers  a suite of scenes that can be used to mea‐
100       sure many aspects of OpenGL (ES) 2.0 performance. The way in which each
101       scene  is rendered is configurable through a set of options. To get the
102       available scenes and their acceptable  options  you  can  use  the  -l,
103       --list-scenes command line option.
104
105       In glmark2-es2-wayland, a benchmark is defined as a scene plus a set of
106       option values.  You can specify the list and order of the benchmarks to
107       run by using the -b, --benchmark command line option (possibly multiple
108       times).  If no benchmarks are specified, a default set of benchmarks is
109       used.  If  a  benchmark  option is not specified it assumes its default
110       value (listed with -l, --list-scenes).
111
112       As a special case, a benchmark description string  is  allowed  to  not
113       contain a scene name (i.e. to start with ':'). In this case, any speci‐
114       fied option values are used as the default values for  benchmarks  fol‐
115       lowing this description string.

EXAMPLES

119       To run the default benchmarks:
120
121              glmark2-es2-wayland
122
123       To  run  a  benchmark  using scene 'shading' with a 'duration' of '5.0'
124       seconds and
125        'shading' of type 'phong':
126
127              glmark2-es2-wayland -b shading:duration=5.0:shading=phong
128
129       To run a series of benchmarks use the -b, --benchmark command line  op‐
130       tion multiple times:
131
132              glmark2-es2-wayland   -b   shading:duration=5.0   -b  build:use-
133              vbo=false -b texture
134
135       To set default option values for benchmarks:
136
137              glmark2-es2-wayland -b :duration=2.0 -b shading -b build -b :du‐
138              ration=5.0 -b texture
