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).
26 * - fixes multiple bugs in flip completion events and timestamping
28 * - object api exposed to userspace
29 * - fermi,kepler,maxwell zbc
31 * - allow concurrent access to bo's mapped read/write.
33 * - add NOUVEAU_GEM_DOMAIN_COHERENT flag
35 * - NVIF ABI modified, safe because only (current) users are test
36 * programs that get directly linked with NVKM.
38 * - implemented limited ABI16/NVIF interop
