+First the internal `include` and `os` directories:
+```
+cp -r /playpen/Linux_for_Tegra/source/public/kernel/nvgpu/drivers/gpu/nvgpu/include/nvgpu/
+cp -r /playpen/Linux_for_Tegra/source/public/kernel/nvgpu/drivers/gpu/nvgpu/os include/
+```

+Then every directory needed by either of those includes:

+Make sure to pull the same version of L4T that you're building on! The structure layout is highly dependant on the version.
