OK, someone from SUSE at the Linuxtag told me that both Cores on my T7200 can run at different frequencies, thats what i've read everywhere too! I have a Thinkpad Z61p with one of these CPUs.
cpufre-info says:
CPUs which need to switch frequency at the same time: 0 1
Perhaps the person who told you they CPUs could operate at different frequencies was mistaken?
Yes, perphaps you're right. I've read the spec pdf from Intel and it says both cores have independent MSRs for controlling Speedstep but both cores must operate at the same frequency. I remember something different from some newspaper but anyway. But this would be fine for power enhancements, right? Or turning off one core would also be nice for battery life?
OK, what the hell is going on here, i've bought a laptop with an T7200 Dual Core CPU!? Is there another CPU installed?
Programmatically, a dual-core CPU is very similar to two single-core CPUs. On recent Linux kernels, even a HyperThreading CPU looks like two separate CPUs at the user level.
Not for forking processes like in a Linux environment, HT is not very good on this issue. ;-) Thx. Frank -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
