| CUDA perfboost bypass, distributed under MIT License | |
| -- @Ristovski | |
| Each CUDA session is boosted to a fixed clock even when no real compute is being done, | |
| this in turn causes the GPU to run hotter, sometimes at considerably higher power. | |
| This preloadable library bypasses that by nuking the NV2080_CTRL_PERF_BOOST ioctl. | |
| Mainly useful for mpv/other video players that utilize hardware video decode (nvdec), | |
| as unlike on Windows, nvdec on linux utilizes CUDA for nvdec<->OpenGL/Vulkan interop. |
