I guess should start to think about how to write igt tests which would target directly at dpt so this kind of issues wouldn't get missed.

From: Ville Syrjälä <[email protected]> Avoid the shrinker evicting the DPT during hibernate and causing an oops. This might also fix DPT induced display faults during high memory pressure (though still don't have a real theory how that could actually happen). Also add a i915.enable_dpt modparam to disable DPT usage via the chicken bit. This can be useful when trying to debug suspected DPT issues.
