CONFIG_PM¶

System Power Management

Type: bool

Help¶

Enable the kernel handles extra power management policies whenever
system enters idle state.

Help¶

Enable the kernel handles extra power management policies whenever
system enters idle state.

Help¶

This option enables the board to implement extra power management
policies whenever the kernel becomes idle. The kernel informs the
power management subsystem of the number of ticks until the next kernel
timer is due to expire.
