  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
