The code presented here is from NVIDIA's internal dev-kernel-3.10 Linux
kernel branch @ commit 85e66d9e32f18056d55cd1781c9c76d80c0bc069.

.../kernel/drivers/gpu/nvgpu/*.[ch]
.../kernel/include/uapi/linux/nvgpu.h
.../kernel/scripts/nvgpu_ucode
.../kernel/include/linux/gk20a.h
.../kernel/include/trace/events/gk20a.h
.../kernel/drivers/gpu/nvgpu/gk20a/

The dev-kernel branch within NVIDIA is used for Android and Linux for Tegra
(L4T) product distributions.  Examples of these:
    . Android: https://android.googlesource.com/kernel/tegra/
    . L4T: https://developer.nvidia.com/linux-tegra

The code presented will be morphed into a form which can be made directly
useful to Nouveau.  That effort includes:

   . Normalizing headers with regard to NVIDIA GPU concepts/engines already
present within Nouveau.
   . Eliminating superfluous code within 'nvgpu.'
   . Bolstering Nouveau code with nvgpu functionality.
   . Adapting to Nouveau run-time behaviour/formulation.
