We should simply return errors while the GPU is turned off, because the sensors
aren't accessable and setting any kind of value doesn't make any sense. Fixes
sensors values reported by "sensors"
Before:
nouveau-pci-0100
Adapter: PCI adapter
GPU core: +0.60 V (min = +0.60 V, max = +1.20 V)
temp1: -0.0°C (high = +95.0°C, hyst = +3.0°C)
(crit = +105.0°C, hyst = +5.0°C)
(emerg = +135.0°C, hyst = +5.0°C)
power1: -22.00 uW
After:
nouveau-pci-0100
Adapter: PCI adapter
GPU core: N/A (min = +0.60 V, max = +1.20 V)
temp1: N/A (high = +95.0°C, hyst = +3.0°C)
(crit = +105.0°C, hyst = +5.0°C)
(emerg = +135.0°C, hyst = +5.0°C)
power1: N/A
Karol Herbst (3):
therm: split return code and value in nvkm_get_temp
hwmon: properly check for errors
subdev/volt/gk104: return error when read fails
