Tegra K1 and later use a GPU that can be driven by the Nouveau driver.
But the GPU is a pure render node and has no display engine, hence the
scanout needs to happen on the Tegra display hardware. The GPU and the
display engine each have a separate DRM device node exposed by the
kernel.
To make the setup appear as a single device, this driver instantiates
a Nouveau screen with each instance of a Tegra screen and forwards GPU
requests to the Nouveau screen. For purposes of scanout it will import
buffers created on the GPU into the display driver. Handles that
userspace requests are those of the display driver so that they can be
used to create framebuffers.
This has been tested with some GBM test programs, as well as kmscube and
weston. All of those run without modifications, but I'm sure there is a
lot that can be improved.
Some fixes contributed by Hector Martin <marcan@marcan.st>.

- properly unwrap resources in ->resource_copy_region()
- support vertex buffers passed by user pointer
- allocate custom stream and const uploader
- silence error message on pre-Tegra124

This adds support for framebuffer modifiers to Nouveau. This will be
used by the Tegra driver to share metadata about the format of buffers
(such as the tiling mode or compression).
Changes in v2:
- remove unused parameters to nouveau_buffer_create()
- move format modifier query code to nvc0 backend
- restrict format modifiers to 2D textures
- implement ->query_dmabuf_modifiers()
Changes in v4:
- add UAPI include path on meson builds
Changes in v5:
- remove unnecessary includes

The existing format modifier definitions were merged prematurely, and
recent work has unveiled that the definitions are suboptimal in several
ways:
- The format specifiers, except for one, are not Tegra specific, but
the names don't reflect that.
- The number space is split into two, reserving 32 bits for some
"parameter" which most of the modifiers are not going to have.
- Symbolic names for the modifiers are not using the standard
DRM_FORMAT_MOD_* prefix, which makes them awkward to use.
- The vendor prefix NV is somewhat ambiguous.
Fortunately, nobody's started using these modifiers, so we can still fix
the above issues. Do so by using the standard prefix. Also, remove TEGRA
from the name of those modifiers that exist on NVIDIA GPUs as well. In
case of the block linear modifiers, make the "parameter" smaller (4
bits, though only 6 values are valid) and don't let that leak into any
of the other modifiers.
Finally, also use the more canonical NVIDIA instead of the ambiguous NV
prefix.
