Oops, sorry. I had meant to reply to your question in the previous
version. The idea was to have this minimal set of tests in libdrm as a
way to demonstrate how to use the various APIs. At the same time, this
is meant to serve as an easy way to validate that everything works from
the comparatively simple libdrm package.

But yes, adding more tests on top of this to IGT is something that I've
been pondering and I certainly wouldn't object if anyone else was going
to attempt to do so. I don't think IGT and libdrm need to be mutually
exclusive, though.
