Device memory can be use in SVM, in which case we do not have any of the existing buffer object. This commit add infrastructure to allow use of device memory without nouveau_bo. Again this is a temporary solution until a rework of GPU memory management. Signed-off-by: Jérôme Glisse <jglisse@redhat.com>

/*
|
|
* 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
