CPU Frequency Control on Arrandale Chips
How well can CPU frequency be controlled on Intel's mobile Arrandale chips? I'm looking at a 2.66GHz i5-560M with HM57 chipset. I will be running real-time software, so need a fixed CPU frequency.
I would like to have two power management states, one dynamic and then another where all cores are held at 2.66GHz no matter what the system load. I need to be able to disable turbo boost and disable speed stepping. How is this done in Linux. Does it work well? Should I just go with an i3 since it does not have turbo boost?
