How to check whether the GPU support power profiling in NVIDIA Visual Profiler

CUDA 5.5 announced that NVIDIA's Visual Profiler supports power, thermal and clock profiling. I tried the profiler on a GTX 480, but it only profile the thermal values in different timestamps, but not power nor clock.

If you are wondering whether your GPU supports power profiling, you can verify it by running the following command.

nvidia-smi -q -d power

This command should return something similar to below with actual power values.

Attached GPUs                       : 1
GPU 0000:00:00.0
    Power Readings
        Power Management            : XXX
        Power Draw                  : XXX
        Power Limit                 : XXX
        Default Power Limit         : XXX
        Enforced Power Limit        : XXX
        Min Power Limit             : XXX
        Max Power Limit             : XXX

If the values are "N/A", then your GPU does not support power profiling.
