8CRITERIA = """
9On bvt-cq this test is not run as a benchmark. (One can find approximate
10performance numbers in the logs though, but they are ignored.) It still
11generates output images and verifies their bit accuracy using MD5 checksums
12which are stored in
13../../deps/glbench/glbench_reference_images.txt (for known good images)
14and in ../../deps/glbench/glbench_knownbad_images.txt (for ignored failures -
15this should be very rare though).
16
17If unknown images are encountered the test fails. To resolve this use an
18image diffing tool like Beyond Compare and visually check differences between
19the unknown image and older versions in ../../deps/glbench-images/.
20Note: it should nearly never be required to remove old versions of good/bad
21images from these directories.

34On bvt, bvt-cq we do not upload performance numbers to the chrome dashboard. We run
35glbench with the "-hasty" option to stay well below the BVT limit of 20
36minutes. This option will run each test at 512x512 resolution only, run it
37only for a fraction of the loops we normally do, and not cool down the
38machine between tests. For this PerfControl is disabled.

40This benchmark executes glbench, a graphics benchmark designed to time how long
41various graphic intensive activities take, which includes measuring:
42  - fill rate
43    - blended
44    - opaque
45  -Z reject rate
46  -triangle rate
47    - no cull
48    - half cull (half triangles backface culled)
49    - full cull (mix of back face and degenerates)
50  - blend rate
51  - texture fetch
52    - nearest
53    - bilinear
54    - trilinear
55  - compute
56    - vertex shader
57    - pixel shader
58    - *fragement shader to test ddx and ddy
59  - attribute fetch
60  - color depth stencil test
61  - *state change
62  - texture upload
63  - read back
