  16/*
  17 * 1.1.1:
  18 *      - added support for tiled system memory buffer objects
  19 *      - added support for NOUVEAU_GETPARAM_GRAPH_UNITS on [nvc0,nve0].
  20 *      - added support for compressed memory storage types on [nvc0,nve0].
  21 *      - added support for software methods 0x600,0x644,0x6ac on nvc0
  22 *        to control registers on the MPs to enable performance counters,
  23 *        and to control the warp error enable mask (OpenGL requires out of
  24 *        bounds access to local memory to be silently ignored / return 0).
  25 * 1.1.2:
  26 *      - fixes multiple bugs in flip completion events and timestamping
  27 * 1.2.0:
  28 *      - object api exposed to userspace
  29 *      - fermi,kepler,maxwell zbc
  30 * 1.2.1:
  31 *      - allow concurrent access to bo's mapped read/write.
  32 * 1.2.2:
  33 *      - add NOUVEAU_GEM_DOMAIN_COHERENT flag
  34 * 1.3.0:
  35 *      - NVIF ABI modified, safe because only (current) users are test
  36 *        programs that get directly linked with NVKM.
  37 * 1.3.1:
  38 *      - implemented limited ABI16/NVIF interop
