| /* |
| * 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 |
