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.
