Where is this block documented or a pointer to the corresponding open userspace user code? Again the ioctls look like they need to be depointered and use __u64. It would be nice if you could document how the command stream and engine work. How does userspace pass addresses to it? straight or via gem objects? how does it stop userspace blt to places it shouldn't etc. I'm getting the feeling this accel enabled driver needs a lot more of a commit message and lot more documentation on what it can be used for.
