Description:
Document the new
ringbuf_in_iramadvanced configuration option for ESP32.This option allows users to control whether ring buffer functions are placed in IRAM or flash. By default, ring buffer functions are placed in flash to save IRAM, except when audio components (
i2s_audio,micro_wake_word) are configured - these automatically enable IRAM placement for real-time audio performance.This change prepares for ESP-IDF 6.0 where flash placement becomes the default behavior.
