15 /*
16  * 1.1.1:
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
21  *        to control registers on the MPs to enable performance counters,
22  *        and to control the warp error enable mask (OpenGL requires out of
23  *        bounds access to local memory to be silently ignored / return 0).
24  * 1.1.2:
25  *      - fixes multiple bugs in flip completion events and timestamping
26  * 1.2.0:
27  * 	- object api exposed to userspace
28  * 	- fermi,kepler,maxwell zbc
29  * 1.2.1:
30  *      - allow concurrent access to bo's mapped read/write.
31  * 1.2.2:
32  *      - add NOUVEAU_GEM_DOMAIN_COHERENT flag
33  * 1.3.0:
34  *      - NVIF ABI modified, safe because only (current) users are test
35  *        programs that get directly linked with NVKM.
36  * 1.3.1:
37  *      - implemented limited ABI16/NVIF interop
