ICInvalidateRange

C Specification

#include <revolution/os.h>
void ICInvalidateRange(void* startAddr, u32 nBytes);

Arguments

startAddr Effective address (not the physical address) .
nBytes Size of range to invalidate.

Return Values

None.

Description

Invalidates a specified range in the instruction cache. The cache data block hit in the instruction cache for the specified range is invalidated. The startAddr argument is truncated to a 32-byte boundary. The final address (startAddr + nBytes), is rounded up to a 32-byte boundary. This command will execute even if the cache is locked (using the ICFreeze function). Furthermore, the requests to invalidate are not passed onto the L2 or data caches.
