This is provided by BIOS/vendor. What kind of Windows tool do you use for detecting frequency steps? What says: cat /proc/acpi/processor/*/throttling Can you also describe the machine (vendor/model). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I will do that when I get home. It should be noted that when a X2 processor is installed it has the full range of speedsteps. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

...

In windows I use the: AMD Power Monitor Version 1.2.3 Hmm, monitor sounds like the steps are really used. and AMD CPUInfo Version CPUinfo sounds as if this is just some static CPU info (I would not give too much for the latter, maybe the stepps are not really used).

There are only two P-States for this property to be exported by the BIOS and that is being done correctly looking at your logs. However the window tool shows other information which is not correct. I will follow up with our windows people but this bug can be closed as it is correct behavior under Linux. I tried the tool version 1.2.3 on my system and only saw it only switch between the two speeds. One thing that might be confusing is it lists a third speed which is that of the North-Bridge and can be ignored as Linux does use North-Bridge P-States but does not output that information in dmesg. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
