Cache management functionality.
This file contains definitions for functions that manage the cache in the Dreamcast, including functions to flush and invalidate the caches.
Flush the data/operand cache.
This function flushes a range of the data/operand cache, forcing a write- back on all of the data in the specified range. This does not invalidate the cache in the process (meaning the blocks will still be in the cache, just not marked as dirty after this has completed). If you wish to invalidate the cache as well, call dcache_inval_range() after calling this function.
|start||The physical address to begin flushing at.|
|count||The number of bytes to flush.|
Invalidate the data/operand cache.
This function invalidates a range of the data/operand cache. If you care about the contents of the cache that have not been written back yet, use dcache_flush_range() before using this function.
|start||The physical address to begin invalidating at.|
|count||The number of bytes to invalidate.|
