15 /*
16 * 1.1.1:
17 * - added support for tiled system memory buffer objects
18 * - added support for NOUVEAU_GETPARAM_GRAPH_UNITS on [nvc0,nve0].
19 * - added support for compressed memory storage types on [nvc0,nve0].
20 * - added support for software methods 0x600,0x644,0x6ac on nvc0
21 * to control registers on the MPs to enable performance counters,
22 * and to control the warp error enable mask (OpenGL requires out of
23 * bounds access to local memory to be silently ignored / return 0).
24 * 1.1.2:
25 * - fixes multiple bugs in flip completion events and timestamping
26 * 1.2.0:
27 * - object api exposed to userspace
28 * - fermi,kepler,maxwell zbc
29 * 1.2.1:
30 * - allow concurrent access to bo's mapped read/write.
