/*
* 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
