/*
 * 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
