[Bug 881362] Re: lava-test powermanagement fails on panda
I am pretty sure it's not workable with OMAP4 to have the cores at
different frequencies, which implies they can't be governed with
different governors. These Colin Cross "coupled cpuidle" patches are
needed for OMAP AIUI.
cpu_idle is disabled atm because smartreflex gets confused when the core
goes down and it loses its context, it sets the core voltage
inappropriately leading to Bad Things. This may get fixed on tilt-3.4
as we go on.
