config RT_USING_PM
bool "Using Power Management device drivers"
default n
help
Enable the system-level power management framework which coordinates
suspend/resume, tickless idle, and device low-power states. Required when
implementing sleep modes beyond simple tick suppression.
if RT_USING_PM
config PM_TICKLESS_THRESHOLD_TIME
int "PM tickless threashold time"
default 2
help
Minimum idle duration (in milliseconds) before the PM core enters
tickless mode. Tune based on wake-up latency vs power savings.
config PM_USING_CUSTOM_CONFIG
bool "PM using custom pm config"
default n
help
Allow BSPs to provide custom PM policy hooks instead of the stock
configuration.
config PM_ENABLE_DEBUG
bool "PM Enable Debug"
default n
help
Print suspend/resume decisions and timing for debugging purposes.
config PM_ENABLE_SUSPEND_SLEEP_MODE
bool "PM Device suspend change sleep mode"
default n
help
Permit PM to change system sleep mode dynamically when devices
suspend; requires board support.
config PM_ENABLE_THRESHOLD_SLEEP_MODE
bool "PM using threshold time change sleep mode"
default n
help
Automatically select light/deep/standby sleep based on idle time
thresholds configured below.
if PM_ENABLE_THRESHOLD_SLEEP_MODE
config PM_LIGHT_THRESHOLD_TIME
int "PM light mode threashold time"
default 5
help
Idle time in milliseconds required before entering light sleep.
config PM_DEEP_THRESHOLD_TIME
int "PM deep mode threashold time"
default 20
help
Idle duration required before requesting deep sleep.
config PM_STANDBY_THRESHOLD_TIME
int "PM standby mode threashold time"
default 100
help
Idle time before transitioning into standby (longest latency)
mode. Increase if standby exit is expensive.
