GLBench runs OpenGL or OpenGL ES microbenchmarks and writes performance numbers to stdout and resulting images to a directory for verification.

For the test to pass the performance numbers have to be better than a predefined threshold, while the resulting images have to be found in a repository of reference images. As the image name encodes the raw pixel MD5 this can be done as a simple file existence check. If we ever get too much pixel variation using a tool like perceptualdiff to waive small differences should be acceptable.

Build for Linux

It might be easier to develop new tests under Linux:

sudo apt-get install libgflags-dev
sudo apt-get install libwaffle-dev
sudo apt-get install waffle-utils (optional)

Executable Options

./glbench -notemp [-save [-outdir=<directory>]]


./glbench -save -outdir=img

Running from the autotest harness

Running the autotest test_that $DUT graphics_GLBench will \

  1. run glbench -save \
  2. first try to identify known buggy images by searching in deps/glbench/glbench_knownbad_images.txt \
  3. then identify good images by searching in deps/glbench/glbench_reference_images.txt \
  4. TODO(ihf): use perceptualdiff to do a fuzzy compare \
  5. raise an error if the image is completely unknown \
  6. report performance numbers back to the harness \

Handling of reference images

Good reference images themselves are located at ./ref_images/glbench_reference_images/
Images that have outstanding defects and an open bug filed are at ./ref_images/glbench_knownbad_images/chromium-bug-NNNNN/
When that bug is closed the directory should be moved to ./ref_images/glbench_fixedbad_images/chromium-bug-NNNNN/ \

To push out new reference images place them in the appropriate directories (create a new bug if needed) and run ./update_glbench_image_filelists.sh to update the image filelists.
