Summary: amdgpu fan behavior doesn't match windows
Product: DRI
Version: XOrg git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org

Some AIB vendor cards have fan profiles tuned to them, which include market=
ing
features like "Zero Frozr", "0 RPM", "Mute Fan" and so on that stop the fan
completely while idle. This doesn't seem to be working with amdgpu, the fan
always spins although some thermal control does seem to work.
My card is MSI RX 470 Gaming X 8G, which has the following vBIOS:
https://www.techpowerup.com/vgabios/185500/185500
Dumping ATOM_Fiji_Fan_Table shows:
usTMin: 4000
usTMed: 6500
usTHigh: 8500
usPWMMin: 2000
usPWMMed: 4000
usPWMHigh: 6000
usTMax: 10900
ucFanControlMode: 1
usFanPWMMinLimit: 18
usFanPWMMaxLimit: 100
usFanPWMStep: 1
usDefaultMaxFanPWM: 100
usMaxFanPWM: 100
usFanRPMMinLimit: 18
usFanRPMMaxLimit: 100
This doesn't seem to really correspond to how it works on Windows, where the
fan stops completely while under 60C (which is how it's also advertised by =
the
vendor). I've not installed any MSI tools there, just the base AMD driver, =
it
also doesn't depend on any autorun .exe, only the base driver is needed for=
it
to behave as advertised on Windows.
So does anyone know what is done different by the Windows driver? Perhaps a
different fan table is used from the vBIOS? Or perhaps the driver has this
logic hardcoded for each partner card?
Can it be done on Linux too?
