The following updates have been made in this commit: - The commit places ring buffer code in flash memory by default. - CONFIG_RINGBUF_PLACE_FUNCTIONS_INTO_FLASH has been removed. - CONFIG_RINGBUF_IN_IRAM is added and can be used to restore the previous memory placement.

Place ring buffer functions in IRAM for better performance.
|
|
By default, ring buffer functions are placed in Flash to save IRAM.
|
|
Enable this option if you need maximum performance for ring buffer operations.
|
|
|
|
Note: This option increases IRAM usage.

Place ISR ringbuf functions (like xRingbufferSendFromISR/xRingbufferReceiveFromISR) into flash.
|
|
This frees up IRAM, but the functions can no longer be called when the cache is disabled
|
|
or from an IRAM interrupt context.
|
|
|
|
This option is not compatible with ESP-IDF drivers which are configured to
|
|
run the ISR from an IRAM context, e.g. CONFIG_UART_ISR_IN_IRAM.
