    config PM_ENABLE
        bool "Support for power management"
        default n
        help
            If enabled, application is compiled with support for power management.
            This option has run-time overhead (increased interrupt latency,
            longer time to enter idle state), and it also reduces accuracy of
            RTOS ticks and timers used for timekeeping.
            Enable this option if application uses power management APIs.

    config PM_DFS_INIT_AUTO
        bool "Enable dynamic frequency scaling (DFS) at startup"
        depends on PM_ENABLE
        default n
        help
            If enabled, startup code configures dynamic frequency scaling.
            Max CPU frequency is set to DEFAULT_CPU_FREQ_MHZ setting,
            min frequency is set to XTAL frequency.
            If disabled, DFS will not be active until the application
            configures it using esp_pm_configure function.

    config PM_PROFILING
        bool "Enable profiling counters for PM locks"
        depends on PM_ENABLE
        default n
        help
            If enabled, esp_pm_* functions will keep track of the amount of time
            each of the power management locks has been held, and esp_pm_dump_locks
            function will print this information.
            This feature can be used to analyze which locks are preventing the chip
            from going into a lower power state, and see what time the chip spends
            in each power saving mode. This feature does incur some run-time
            overhead, so should typically be disabled in production builds.

    config PM_TRACE
        bool "Enable debug tracing of PM using GPIOs"
        depends on PM_ENABLE
        default n
        help
            If enabled, some GPIOs will be used to signal events such as RTOS ticks,
            frequency switching, entry/exit from idle state. Refer to pm_trace.c
            file for the list of GPIOs.
            This feature is intended to be used when analyzing/debugging behavior
            of power management implementation, and should be kept disabled in
            applications.

    config PM_SLP_IRAM_OPT
        bool "Put lightsleep related codes in internal RAM"
        depends on FREERTOS_USE_TICKLESS_IDLE
        help
            If enabled, about 1.8KB of lightsleep related source code would be in IRAM and chip would sleep
            longer for 760us at most each time.
            This feature is intended to be used when lower power consumption is needed
            while there is enough place in IRAM to place source code.

    config PM_RTOS_IDLE_OPT
        bool "Put RTOS IDLE related codes in internal RAM"
        depends on FREERTOS_USE_TICKLESS_IDLE
        help
            If enabled, about 260B of RTOS_IDLE related source code would be in IRAM and chip would sleep
            longer for 40us at most each time.
            This feature is intended to be used when lower power consumption is needed
            while there is enough place in IRAM to place source code.

    config PM_SLP_DISABLE_GPIO
        bool "Disable all GPIO when chip at sleep"
        depends on FREERTOS_USE_TICKLESS_IDLE
        help
            This feature is intended to disable all GPIO pins at automantic sleep to get a lower power mode.
            If enabled, chips will disable all GPIO pins at automantic sleep to reduce about 200~300 uA current.
            If you want to specifically use some pins normally as chip wakes when chip sleeps,
            you can call 'gpio_sleep_sel_dis' to disable this feature on those pins.
            You can also keep this feature on and call 'gpio_sleep_set_direction' and 'gpio_sleep_set_pull_mode'
            to have a different GPIO configuration at sleep.
            Waring: If you want to enable this option on ESP32, you should enable `GPIO_ESP32_SUPPORT_SWITCH_SLP_PULL`
            at first, otherwise you will not be able to switch pullup/pulldown mode.

    config PM_SLP_DEFAULT_PARAMS_OPT
        bool

    config PM_POWER_DOWN_CPU_IN_LIGHT_SLEEP
        bool "Power down CPU in light sleep"
        depends on IDF_TARGET_ESP32C3 || IDF_TARGET_ESP32S3

        default y
        help
            If enabled, the CPU will be powered down in light sleep. On esp32c3 soc, enabling this
            option will consume 1.68 KB of internal RAM and will reduce sleep current consumption
            by about 100 uA. On esp32s3 soc, enabling this option will consume 8.58 KB of internal
            RAM and will reduce sleep current consumption by about 650 uA.

    config PM_POWER_DOWN_TAGMEM_IN_LIGHT_SLEEP
        bool "Power down I/D-cache tag memory in light sleep"
        depends on IDF_TARGET_ESP32S3 && PM_POWER_DOWN_CPU_IN_LIGHT_SLEEP
        default y
        help
            If enabled, the I/D-cache tag memory will be retained in light sleep. Depending on the the
            cache configuration, if this option is enabled, it will consume up to 9 KB of internal RAM.
