does the precedent version set the governor for all cpu(s) ?

I'm unable to reproduce with my quad-core SandyBridge system.
Hi Matt, to Comment 5: I suppose that the sandy bridge system is a Intel system, as I wrote in Comment 2 I have the issue only with AMD systems.

Juergen, I emailed the cpufreq@vger.kernel.org mailing list looking for insight and CC'd you on it. The cpufrequtils maintainer responded and wants the full output of cpufreq-info.
I sent the full output of cpufreq-info to Dominik.
'emerge gpsdrive' works now for me with gpsdrive-2.11-r3: root@lynx:/root(12)# emerge -vD gpsdrive ... * >>> app-misc/gpsdrive-2.11-r3 merged. >>> Auto-cleaning packages... >>> No outdated packages were found on your system. * GNU info directory index is up-to-date. even with boost-1.42.0-r2.
Sorry for the last comment, it went to the wrong tab.
(In reply to comment #10) > I sent the full output of cpufreq-info to Dominik. Would have been better if you'd Replyed to all. I didn't get the email.

So it seems as if this isn't actually a cpufrequtils bug (or a bug at all?) Is it causing any problems?
'mat cpufreq-set' says about option '-r': -r --related modify all hardware-related CPUs at the same time What means 'hardware-related CPUs'? I assumed, that the Phenom X6 1090T has six hardware-related CPUs, the Phenom X4 965 has four hardware-related CPUs and Intel Core Quad Q9650 has four hardware-related CPUs. At least the command: root@impala:/root(7)# grep "model name" /proc/cpuinfo | head -n1; for d in /sys/devices/system/cpu/cpu? ; do echo " -- d=$d --"; for f in related_cpus ; do echo -n " $f : "; cat $d/cpufreq/$f; done ; done model name : AMD Phenom(tm) II X4 965 Processor -- d=/sys/devices/system/cpu/cpu0 -- related_cpus : 0 -- d=/sys/devices/system/cpu/cpu1 -- related_cpus : 1 -- d=/sys/devices/system/cpu/cpu2 -- related_cpus : 2 -- d=/sys/devices/system/cpu/cpu3 -- related_cpus : 3 shows four CPUs for the Phenom X4 965. But it seems that, that 'cpufreq-set -r' sets the parameters for all CPUs only if /sys/devices/system/cpu/cpu*/cpufreq/ contains the information about all CPUs for each sys/devices/system/cpu/cpu? as for Intel Core Duo T8300 or Intel Xeon CPU W3520: rose@orca:/home/rose(1)$ grep "model name" /proc/cpuinfo | head -n1; for d in /sys/devices/system/cpu/cpu? ; do echo " -- d=$d --"; for f in affected_cpus related_cpus ; do echo -n " $f : "; cat $d/cpufreq/$f; done ; done model name : Intel(R) Xeon(R) CPU W3520 @ 2.67GHz -- d=/sys/devices/system/cpu/cpu0 -- affected_cpus : 0 related_cpus : 0 1 2 3 4 5 6 7 -- d=/sys/devices/system/cpu/cpu1 -- affected_cpus : 1 related_cpus : 0 1 2 3 4 5 6 7 -- d=/sys/devices/system/cpu/cpu2 -- affected_cpus : 2 related_cpus : 0 1 2 3 4 5 6 7 -- d=/sys/devices/system/cpu/cpu3 -- affected_cpus : 3 related_cpus : 0 1 2 3 4 5 6 7 -- d=/sys/devices/system/cpu/cpu4 -- affected_cpus : 4 related_cpus : 0 1 2 3 4 5 6 7 -- d=/sys/devices/system/cpu/cpu5 -- affected_cpus : 5 related_cpus : 0 1 2 3 4 5 6 7 -- d=/sys/devices/system/cpu/cpu6 -- affected_cpus : 6 related_cpus : 0 1 2 3 4 5 6 7 -- d=/sys/devices/system/cpu/cpu7 -- affected_cpus : 7 related_cpus : 0 1 2 3 4 5 6 7 So it is for me until now not possible to set the governor for all cpus with one cpufreq-set statement for Intel Core Quad Q9650 and AMD Phenom. I can survive this, but it would be handy to have such a command. And as Dominik told, the comming cpupower command will have such a option.

At least the command: Right. I'm not sure why some CPUs' cores are controlled independently and others together. Whatever the case is, it seems that cpufrequtils is only doing what it's told. This could mean that we misunderstand what exactly it's supposed to be doing, or there could be a bug in the kernel. If previous kernels caused cpufrequtils to act differently, then it may be a bug. I'm going to close this bug until a time when we have some better idea that this is actually a bug.
