This governor raises the CPU clock much faster than ondemand, and 408MHz seems to be a spot where the SoC will power down a lot of blocks when idle. Also, perhaps the minimum setting should be 1GHz at boot time and not dropped until the UI is up and running, since this affects the overall boot speed by quite a bit, and that's the first impression any user gets of a distro -- how long it takes to get my login prompt or splash screen. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
