/*

 * 1.1.1:

 *  - added support for tiled system memory buffer objects

 *      - added support for NOUVEAU_GETPARAM_GRAPH_UNITS on [nvc0,nve0].

 *      - added support for compressed memory storage types on [nvc0,nve0].

 *      - added support for software methods 0x600,0x644,0x6ac on nvc0

 *        to control registers on the MPs to enable performance counters,

 *        and to control the warp error enable mask (OpenGL requires out of

 *        bounds access to local memory to be silently ignored / return 0).

 * 1.1.2:

 *      - fixes multiple bugs in flip completion events and timestamping

 * 1.2.0:

 *  - object api exposed to userspace

 *  - fermi,kepler,maxwell zbc

 * 1.2.1:

 *      - allow concurrent access to bo's mapped read/write.

 * 1.2.2:

 *      - add NOUVEAU_GEM_DOMAIN_COHERENT flag

 * 1.3.0:

 *      - NVIF ABI modified, safe because only (current) users are test

 *        programs that get directly linked with NVKM.

 * 1.3.1:

 *      - implemented limited ABI16/NVIF interop
