-``interactive``
-----------------
-
-The CPUfreq governor `interactive` is designed for latency-sensitive,
-interactive workloads. This governor sets the CPU speed depending on
-usage, similar to `ondemand` and `conservative` governors, but with a
-different set of configurable behaviors.
-
-The tunable values for this governor are:
-
-``above_hispeed_delay``
-        When speed is at or above hispeed_freq, wait for
-        this long before raising speed in response to continued high load.
-        The format is a single delay value, optionally followed by pairs of
-        CPU speeds and the delay to use at or above those speeds.  Colons can
-        be used between the speeds and associated delays for readability.  For
-        example:
-
-           80000 1300000:200000 1500000:40000
-
-        uses delay 80000 uS until CPU speed 1.3 GHz, at which speed delay
-        200000 uS is used until speed 1.5 GHz, at which speed (and above)
-        delay 40000 uS is used.  If speeds are specified these must appear in
-        ascending order.  Default is 20000 uS.
-
-``boost``
-        If non-zero, immediately boost speed of all CPUs to at least
-        hispeed_freq until zero is written to this attribute.  If zero, allow
-        CPU speeds to drop below hispeed_freq according to load as usual.
-        Default is zero.
-
-``boostpulse``
-        On each write, immediately boost speed of all CPUs to
-        hispeed_freq for at least the period of time specified by
-        boostpulse_duration, after which speeds are allowed to drop below
-        hispeed_freq according to load as usual. Its a write-only file.
-
-``boostpulse_duration``
-        Length of time to hold CPU speed at hispeed_freq
-        on a write to boostpulse, before allowing speed to drop according to
-        load as usual.  Default is 80000 uS.
-
-``go_hispeed_load``
-        The CPU load at which to ramp to hispeed_freq.
-        Default is 99%.
-
-``hispeed_freq``
-        An intermediate "high speed" at which to initially ramp
-        when CPU load hits the value specified in go_hispeed_load.  If load
-        stays high for the amount of time specified in above_hispeed_delay,
-        then speed may be bumped higher.  Default is the maximum speed allowed
-        by the policy at governor initialization time.
-
-``io_is_busy``
-        If set, the governor accounts IO time as CPU busy time.
-
-``min_sample_time``
-        The minimum amount of time to spend at the current
