Case study

NVFC: recovering undocumented NvAPI GPU controls

NVFC implements undocumented NvAPI interfaces for NVIDIA GPU monitoring and configuration. The author recovered the interfaces by observing nvapi_QueryInterface calls in existing utilities; the C++ tool reads clocks, voltage, temperature and fan state and can set fan behavior.
