#include <revolution/os.h> void DCStoreRange(void* startAddr, u32 nBytes);
startAddr |
Effective address (not the physical address) . |
|---|---|
nBytes |
Size of region to be stored. |
None.
Securely updates specified memory range with modified data in cache. The startAddr argument will be rounded down to the closest 32-byte boundary, while the end address (startAddr + nBytes) will be rounded up to the closest 32-byte boundary.
Be aware that even if the cache is disabled or frozen (via the DCFreeze function), this command will still execute.
This function invokes a sync after storing the specified range. This means that this function will stall until the CPU detects that the data has been written to main memory. Since this operation can be costly, consider calling the DCStoreRangeNoSync function on several ranges followed by a separate call to the PPCSync function. Be aware that DMA transfers into and out of the locked cache are not affected by the PPCSync function.
