  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
