INTEL_blackhole has been useful to benchmark CPU side changes in the GL driver, by having the application spin command buffers as fast as possible (since they complete immediately).
We would like to use this with applications without having to modify them, hence this idea of setting the default value of
GL_BLACKHOLE_RENDER_INTEL through an environment variable.
This is probably not to the taste of a bunch of people, so I'm looking for alternatives.
Thanks for your feedback.
