wf_fcu_fan_get_rpm is returning EFAULT when reading the values for the cpu pump controls on the PowerMac7,3. Also, wf_fcu_get_pump_minmax is unable to get the real limits and falls back to using the defaults.
Here is the output when DEBUG is defined: wf_fcu: FCU Initialized, RPM fan shift is 3 Looking up FCU controls in device-tree... control: rpm0, type: fan-rpm-control matching location: CPU B PUMP, reg: 0x00000010 location match, name: cpu-pump-1 wf_fcu: pump min/max for cpu-pump-1 set to: [1250..3200] RPM wf_pm72: Liquid cooling pump(s) detected, using new algorithm ! control: rpm1, type: fan-rpm-control matching location: CPU A PUMP, reg: 0x00000012 location match, name: cpu-pump-0 wf_fcu: pump min/max for cpu-pump-0 set to: [1250..3200] RPM control: rpm2, type: fan-rpm-control matching location: DRIVE BAY, reg: 0x00000014 location match, name: drive-bay-fan wf_fcu: fan min/max for drive-bay-fan set to: [300..7000] RPM control: rpm3, type: fan-rpm-control matching location: CPU A INTAKE, reg: 0x00000016 location match, name: cpu-front-fan-0 wf_fcu: fan min/max for cpu-front-fan-0 set to: [300..3200] RPM control: rpm4, type: fan-rpm-control matching location: CPU A EXHAUST, reg: 0x00000018 location match, name: cpu-rear-fan-0 wf_fcu: fan min/max for cpu-rear-fan-0 set to: [300..3200] RPM control: rpm5, type: fan-rpm-control matching location: CPU B INTAKE, reg: 0x0000001a location match, name: cpu-front-fan-1 wf_fcu: fan min/max for cpu-front-fan-1 set to: [300..3200] RPM control: rpm6, type: fan-rpm-control matching location: CPU B EXHAUST, reg: 0x0000001c location match, name: cpu-rear-fan-1 wf_fcu: fan min/max for cpu-rear-fan-1 set to: [300..3200] RPM control: pwm1, type: fan-pwm-control matching location: BACKSIDE, reg: 0x00000032 location match, name: backside-fan control: pwm2, type: fan-pwm-control matching location: SLOT, reg: 0x00000034 location match, name: slots-fan control: adc0, type: power-sensor control: adc1, type: power-sensor control: adc2, type: power-sensor control: adc3, type: power-sensor control: gpi0, type: gpi-sensor control: gpi1, type: gpi-sensor Andreas. -- Andreas Schwab, sch...@linux-m68k.org GPG Key fingerprint = 58CA 54C7 6D53 942B 1756 01D3 44D5 214B 8276 4ED5 "And now for something completely different." _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
