But instead of adding the PWR features like firmware loading and communication with PMU firmware, we add the DVFS (Dynamic Voltage and Frequency Scaling), which is one of the PMU firmware's jobs on dGPUs, in this patch. This refers to the idle signals provided by the NVIDIA hardware and tries to adjust the performance level based on the calculated target. The reclocking policy can be fine-tuned later when we have more real use cases. Signed-off-by: Vince Hsu Signed-off-by: Ben Skeggs --- Reading git-diff-tree failed
