    Powersave locks you in at the low speed more often than not.

    No thanks ;)

    Ondemand is fine. Although the kernel has its own omap profiles so I don't even know if these even actually make a difference.

    Have you tested to see if it makes a difference?

    Like I said, there are omap specific cpu profiles in the kernel as well as these default governors. I am unsure if they even work...

    Someone else more schooled in the kernel than me will have to respond.

    Alright, so in my kernel, these are the governors and how I have them set. Pretty much stock.

    # CPU Power Management
    #
    CONFIG_CPU_FREQ=y
    CONFIG_CPU_FREQ_TABLE=y
    # CONFIG_CPU_FREQ_DEBUG is not set
    CONFIG_CPU_FREQ_STAT=y
    # CONFIG_CPU_FREQ_STAT_DETAILS is not set
    CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
    # CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE is not set
    # CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
    # CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND is not set
    # CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
    CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
    # CONFIG_CPU_FREQ_GOV_POWERSAVE is not set
    CONFIG_CPU_FREQ_GOV_USERSPACE=y
    CONFIG_CPU_FREQ_GOV_ONDEMAND=y
    # CONFIG_CPU_FREQ_GOV_CONSERVATIVE is not set
    CONFIG_CPU_FREQ_MIN_TICKS=2
    CONFIG_CPU_FREQ_SAMPLING_LATENCY_MULTIPLIER=500
    CONFIG_CPU_IDLE=y
    CONFIG_CPU_IDLE_GOV_LADDER=y
    CONFIG_CPU_IDLE_GOV_MENU=y


    Now, there is another section in the kernel config that lists this:

    CONFIG_OMAP_SMARTREFLEX=y

    OMAP Frequently Asked Questions - TI

    Now what I was saying is, I don't know if that replaces the default governor's functions, or if it works in tandem with them.

    I use ondemand. Not sure if I even notice a difference between it and conservative, but that's what I use.
