This series is intended to add support for shutting down the GPU on kernel shutdown/reboot using the ->shutdown() hook, similar to what amdgpu does. This is mainly intended to workaround a bios issue on the P50 that was preventing nouveau from initializing the dedicated GM107 GPU on that system properly. You can find more details on this issue in the patch labeled "Shut down GPU on kernel

fb_do_apertures_overlap is returning wrong value when one aperture is completely whithin the other. Add generic ranges_overlap macro (probably kernel.h candidate) and use it here.

From: Thierry Reding <treding at nvidia.com> Hi Ben, these are a couple of patches that are in preparation for adding GV11B support. The fundamental issue that these are trying to solve is that the GV11B is the first Tegra incarnation of the GPU where the aperture really matters. All prior generations would accept any of them. For dGPUs we usually allocate memory in VRAM, so the default aperture (0) is correct. However, on Tegra the buffers are allocated in system memory, and since the GPU actually cares about the aperture, we need to ensure that the ap...

Can GK20A take comptags with aperture set to system memory? For some reason I can recall, I was under th...

From: Thierry Reding <treding at nvidia.com> The gk20a (as well as all subsequent Tegra instantiations of the GPU) do in fact use the same apertures as regular GPUs. Prior to gv11b there are no checks in hardware for the aperture, so we get away with setting VRAM as the aperture for buffers that are actually in system memory.
