CONFIG_CACHE_FLUSHING¶

Enable d-cache flushing mechanism

Enable cache flushing mechanism

Type: bool

Help¶

This links in the sys_cache_flush() function, which provides a way to flush multiple lines of the d-cache. If the d-cache is present, set this to y. If the d-cache is NOT present, set this to n.

Help¶

This links in the sys_cache_flush() function. A mechanism for flushing the cache must be selected as well. By default, that mechanism is discovered at runtime.
