/*
|
|
* 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
