Ben Skeggs a76fb4e8ff drm/nouveau: detect vram amount once, and save the value
As opposed to repeatedly reading the amount back from the GPU every
time we need to know the VRAM size.

We should now fail to load gracefully on detecting no VRAM, rather than
something potentially messy happening.

Pauli Nieminen bf62acdef8 drm/nouveau: Add ttm page pool debugfs file.
ttm_page_pool file is hooked ttm_page_alloc_debugfs for pool
allocator state.

Ben Skeggs b42861f40f drm/nouveau: allow retrieval of vbios image from debugfs
It's very useful to be able to access this without additional tools for
debugging purposes.

Ben Skeggs 9a391ad8a2 drm/nv50: switch to indirect push buffer controls
PFIFO on G80 and up has a new mode where the main ring buffer is simply a
ring of pointers to indirect buffers containing the actual command/data
packets.  In order to be able to implement index buffers in the 3D driver
we need to be able to submit data-only push buffers right after the cmd
packet header, which is only possible using the new command submission
method.

This commit doesn't make it possible to implement index buffers yet, some
userspace interface changes will be required, but it does allow for
testing/debugging of the hardware-side support in the meantime.

Ben Skeggs 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.
