amdgpu coolers never stoping linux

Description


1. On Windows 10 & macOS coolers may be parked in mode 0 rpm.
AMDGPU "pwm1_enable" can work only in mode=1, it is interesting that the rotation speed static.

How hard can it be to implement?

The initial implementation with support for throttling of the cooler.
Have already been implemented, not enough reading VBIOS from EFI settings to automatically stop the cooler in idle.
EFI VBIOS for macOS & Windows driver detected coolers supported noise fan 0% to idle card, but not linux amdgpu....

Lzzy can change /sys/class/drm/card0/device/power meters/hwmon1/pwm1=0 revs but under load it is fraught with burnout,
nv support coolers speed pwm1_enable
* 0=NONE - Card control PW?
* 1=MANUAL
* 2=AUTO - OS control PW?

2. When parking in cooler 0 rpm gauge still shows the rotation of coolers (lm-sensors), but the physical status LED/Fan stopped
