Module flags

CPU frequency driver flags.

Constants

ASYNC_NOTIFICATION

Allows post-change notifications outside of the target() routine.

CONST_LOOPS

Platform where constants like loops_per_jiffy are unaffected by frequency changes.

HAVE_GOVERNOR_PER_POLICY

Supports multiple clock domains with per-policy governors in cpu/cpuN/cpufreq/.

IS_COOLING_DEV

Register driver as a thermal cooling device automatically.

NEED_INITIAL_FREQ_CHECK

Ensure CPU starts at a valid frequency from the driver’s freq-table.

NEED_UPDATE_LIMITS

Driver needs to update internal limits even if frequency remains unchanged.

NO_AUTO_DYNAMIC_SWITCHING

Disallow governors with dynamic_switching capability.
