Hi all,
This series picks up the work carried out by the Asahi project for
shmem-backed GEM objects. This initial version is meant to kickstart the
discussion on this topic, as the bindings will be clearly needed by Tyr
and other drivers.
It has been tested on both AGX and Tyr successfully.
I did provide a minor fix for a missing #include, but I did not touch
this code otherwise so far. Even the rebase was done by Janne Grunnau.
