            ESP32 ROM contains parts of newlib C library, including printf/scanf family
            of functions. These functions have been compiled with so-called "nano"
            formatting option. This option doesn't support 64-bit integer formats and C99
            features, such as positional arguments.

            For more details about "nano" formatting option, please see newlib readme file,
            search for '--enable-newlib-nano-formatted-io':
            https://sourceware.org/newlib/README

            If this option is enabled, build system will use functions available in
            ROM, reducing the application binary size. Functions available in ROM run
            faster than functions which run from flash. Functions available in ROM can
            also run when flash instruction cache is disabled.

            If you need 64-bit integer formatting support or C99 features, keep this
            option disabled.

            ESP-MESH utilizes beacon frames to detect and resolve root node conflicts (see documentation). However the
            default length of a beacon frame can simultaneously hold only five root node identifier structures,
            meaning that a root node conflict of up to five nodes can be detected at one time. In the occurence of
            more root nodes conflict involving more than five root nodes, the conflict resolution process will detect
            five of the root nodes, resolve the conflict, and re-detect more root nodes. This process will repeat
            until all root node conflicts are resolved. However this process can generally take a very long time.

            To counter this situation, the beacon frame length can be increased such that more root nodes can be
            detected simultaneously. Each additional root node will require 36 bytes and should be added ontop of the
            default beacon frame length of
            752 bytes. For example, if you want to detect 10 root nodes simultaneously, you need to set the beacon
            frame length as
            932 (752+36*5).

            Setting a longer beacon length also assists with debugging as the conflicting root nodes can be identified

        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 CONFIG_ESP32_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_USE_RTC_TIMER_REF
        bool "Use RTC timer to prevent time drift (EXPERIMENTAL)"
        depends on PM_ENABLE && (ESP32_TIME_SYSCALL_USE_RTC || ESP32_TIME_SYSCALL_USE_RTC_FRC1)
        default n
        help
            When APB clock frequency changes, high-resolution timer (esp_timer)
            scale and base value need to be adjusted. Each adjustment may cause
            small error, and over time such small errors may cause time drift.
            If this option is enabled, RTC timer will be used as a reference to
            compensate for the drift.
            It is recommended that this option is only used if 32k XTAL is selected
            as RTC clock source.

    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.
