17  * 	- added support for tiled system memory buffer objects
18  *      - added support for NOUVEAU_GETPARAM_GRAPH_UNITS on [nvc0,nve0].
19  *      - added support for compressed memory storage types on [nvc0,nve0].
20  *      - added support for software methods 0x600,0x644,0x6ac on nvc0
25  *      - fixes multiple bugs in flip completion events and timestamping
27  * 	- object api exposed to userspace
28  * 	- fermi,kepler,maxwell zbc
30  *      - allow concurrent access to bo's mapped read/write.
32  *      - add NOUVEAU_GEM_DOMAIN_COHERENT flag
34  *      - NVIF ABI modified, safe because only (current) users are test
37  *      - implemented limited ABI16/NVIF interop
