The KeInvalidateRangeAllCaches routine flushes the specified virtual address range from all processor caches.
BaseAddressA pointer to the base of the region to be flushed.
LengthThe size of the region to be flushed, in bytes.
The KeInvalidateRangeAllCaches routine flushes the specified virtual address range on each processor's caches and marks each cache's contents invalid. The processor caches are guaranteed to have completed the flush operation before KeInvalidateRangeAllCaches returns.
This function is available on all platforms and supersedes KeInvalidateAllCaches. Not all architectures, such as Arm64, support a reliable way to flush the entire cache, so KeInvalidateAllCaches is not available on all platforms. It is also significantly more efficient to flush the particular memory range affected than the entire cache contents.
This function flushes the cache for all virtual mappings of the same underlying physical memory.
