Message

Resending this because, among other things, the patches themselves did
not have dri-devel on cc.

------------------

Hi all.

I will refrain from writing a changelog here, since I have rewritten
this series from the ground up in C. I removed the Rust-for-Linux people
from the loop for now, since this has become a bit tangential to Rust.

Lastly, this is no longer RFC.

For those looking for a branch instead, please see [0].

I have tested this with the decoder tool I wrote at [1]. Unfortunately
the dumps are too large to share.

You will notice that I added support for a new query. I am still working
on the IGT tests for that. 


Let me know what you think.
