This is great thread for an overview on the power management. I've got a BBB and its now 3.8. Has anybody tried the PM APIs or got some pointers.? I've compiled the Ubuntu for BBB (3.8.13-bone32) and it has some options for CPU power management - though haven't got to dig into what they do yet. Anybody tinkering in this area?
