Me too, however we had a long discussion (see
CAN58jiuVOJMX2-U=Odqrjtr1agNPSRnS1nXURYitc8AC8FgH3g@xxxxxxxxxxxxxx) and
Oleksandr and others thought that it would require too much drivers code
to change cpu frequency directly in Xen on ARM
(CAH_mUMNQLHeOWFC_SNB_8BjBz9rOs=moYOUFFhtOXo_WPZTa7w@xxxxxxxxxxxxxx and
CAH_mUMM0iSCcCcYz1B13p5YdS+wvgBOMVJh-871v0Ga0f1bH8Q@xxxxxxxxxxxxxx).

They might be right.
