CONFIG_RING_BUFFER

Enable ring buffers

Type: bool

Help

Enable usage of ring buffers. This is similar to kernel FIFOs but ring buffers manage their own buffer memory and can store arbitrary data. For optimal performance, use buffer sizes that are a power of 2.

Defaults

No defaults. Implicitly defaults to n.
