[Resolved] How to set nouveau clock level via kernel parameter?

My nvidia card (NV40) temperature is >= 90°C when using nouveau, I want to set my card to lower power mode,
I checked https://nouveau.freedesktop.org/wiki/Ke … arameters/ and found that the kernel parameter NvClkMode seems can re-clock my card, but I don't known the value range of this parameter.

Update:
https://nouveau.freedesktop.org/wiki/Ke … arameters/
By set nouveau.pstate=1, the supported power levels can be found by `cat /sys/class/drm/cardN/device/pstate`, and can be changed runtime.
