19 * 1.1.1:
20 * - added support for tiled system memory buffer objects
21 * - added support for NOUVEAU_GETPARAM_GRAPH_UNITS on [nvc0,nve0].
22 * - added support for compressed memory storage types on [nvc0,nve0].
23 * - added support for software methods 0x600,0x644,0x6ac on nvc0
24 * to control registers on the MPs to enable performance counters,
25 * and to control the warp error enable mask (OpenGL requires out of
26 * bounds access to local memory to be silently ignored / return 0).
27 * 1.1.2:
28 * - fixes multiple bugs in flip completion events and timestamping
29 * 1.2.0:
30 * - object api exposed to userspace
31 * - fermi,kepler,maxwell zbc
32 * 1.2.1:
33 * - allow concurrent access to bo's mapped read/write.
34 * 1.2.2:
35 * - add NOUVEAU_GEM_DOMAIN_COHERENT flag
36 * 1.3.0:
37 * - NVIF ABI modified, safe because only (current) users are test
38 * programs that get directly linked with NVKM.
39 * 1.3.1:
40 * - implemented limited ABI16/NVIF interop
