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.

The fans ramping up is a known issue. One way to work around it is to disable SMP. To disable SMP, put in /boot/loader.conf kern.smp.disabled=1 Best regards Michael > > > Thanks in advance, > > Javi. > > _______________________________________________ > freebsd-ppc@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-ppc > To unsubscribe, send any mail to "freebsd-ppc-unsubscribe@freebsd.org" From owner-freebsd-ppc@freebsd.org Thu Oct 29 12:37:01 2020 Return-Path: Delivered-To: freebsd-ppc@mailman.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.nyi.freebsd.org (Postfix) with ESMTP id 4D84844FA4C for ;

But the heatsink in literally four times the size of the Xserve. And to be honest I don't know what they were thinking when Apple was designing the airflow of the case, because is less than optimal in many ways. I know that is an overheating issue because the FreeBSD kernel start spitting a message saying (CPU Diode is 134C, and maximum temperature allowed is 90C). After that the blowers got to maximum speed for few second. Sometime it can actually regulate the temperature and it won't shut down. But if it continues to print the same message for 5 seconds the kernel will initiate shutdown automatically. I really want to get cpufreq + powerd working because if this happens you can also underclock the cpu to balance out the heat issue. But it really seems to me that the implementation for G5 in cpufreq is a mess. So I guess that I'll need to jump into that. I've never used the kernel debugger (DDB) on a powerpc (my idea is to use it via serial port). If anybody has any tips in this regard I'm all ears. Javi.

If someone were to write a BSD-licensed platform function interpreter, it would be pretty easy to hook it in. The (GPL) linux interpreter is an example of a platform function interpreter. https://github.com/torvalds/linux/blob/master/arch/powerpc/platforms/powermac/pfunc_core.c Darwin has one as well but when I looked at it it was a bunch of Objective C that would be less work to just reimplement rather than trying to use. (I think the license wasn't BSD either) The device tree has a series of platform functions that contain bytecode that the kernel runs to do a function like change the cpu clockrate, etc. It's done this way so it can be run without having to context-switch, and have platform drivers that automatically work on all Mac99 machines. I'm not sure off the top of my head what documentation there is available.
