Hello all, I'm new in this mailing list, although I've been going back and forth with PPC (G4/G5) and FreeBSD since 9.0. I have a question that perhaps some of you already stumbled across, but I wanted to know if there is a way to get it to work before I jump in the code. I have a xserve G5 dual 2.3Ghz, and I installed FreeBSD 12.1. Works quite well, but I cannot get cpufreq + powerd/powerdxx to work at all. I get this: # powerdxx powerd++: (ENOFREQ) cannot access dev.cpu.0.freq, at least the first CPU core must support frequency updates This is the relevant part of sysctl: # sysctl dev.cpu dev.cpu.1.%parent: cpulist0 dev.cpu.1.%pnpinfo: name=PowerPC,G5 dev.cpu.1.%location: dev.cpu.1.%driver: cpu dev.cpu.1.%desc: Open Firmware CPU dev.cpu.0.%parent: cpulist0 dev.cpu.0.%pnpinfo: name=PowerPC,G5 dev.cpu.0.%location: dev.cpu.0.%driver: cpu dev.cpu.0.%desc: Open Firmware CPU dev.cpu.%parent: The issue is that after few minutes the fans ramp up to insane levels, and my goal with this is to use powerd or powerdxx to manage the situation. Thanks in advance, Javi.
