From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> Inspired by the recent introduction of the engine class and instance concept, and a chat with Chris Wilson about a potential unification of PCI id based device discovery across multiple userspace components, I have cooked up two patches to gather some opinions on whether this sort of uAPI would be interesting for a wider audience. First patch is basically and old idea by Jon Bloomfield on how to do engine discovery, while the second one is just a quick hack to show how a similar approach could work for execbuffer2. Both patches are compile tested only and intended only to start a discussion.
