 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
