a5cf68b04b drm/nouveau: Rework tile region handling.
The point is to share more code between the PFB/PGRAPH tile region
hooks, and give the hardware specific functions a chance to allocate
per-region resources.

nv0x-nv4x should be mostly fine, nv50 doesn't work yet.

b8c157d3a9 drm/nouveau: only expose the object classes that are supported by the chipset
We previously added all the available classes for the entire generation,
even though the objects wouldn't work on the hardware.

a6a1a38075 drm/nouveau: use object class structs more extensively
The structs themselves, as well as the non-sw object creation function are
probably very misnamed now.  That's a problem for later :)

50536946fa drm/nouveau: store engine type in gpuobj class structs
We will eventually want to address hw engines other than PGRAPH.

3945e47543 drm/nouveau: Refactor context destruction to avoid a lock ordering issue.
The destroy_context() engine hooks call gpuobj management functions to
release the channel resources, these functions use HARDIRQ-unsafe locks
whereas destroy_context() is called with the HARDIRQ-safe
context_switch_lock held, that's a lock ordering violation.

Push the engine-specific channel destruction logic into destroy_context()
and let the hardware-specific code lock and unlock when it's actually
needed. Change the engine destruction order to avoid a race in the small
gap between pgraph and pfifo context uninitialization.

f56cb86f9a drm/nouveau: add instmem flush() hook
This removes the previous prepare_access() and finish_access() hooks, and
replaces it with a much simpler flush() hook.

All the chipset-specific code before nv50 has its use removed completely,
as it's not required there at all.

6ee738610f drm/nouveau: Add DRM driver for NVIDIA GPUs
This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.

This driver is a KMS-based driver and requires a compatible nouveau
userspace libdrm and nouveau X.org driver.

This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.

This driver is reverse engineered, and is in no way supported by nVidia.

Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
is available, and the kms driver should support driving nearly all
output types (displayport is under development still) along with supporting
suspend/resume.

This work is all from the upstream nouveau project found at
nouveau.freedesktop.org.
