Flush a range of cache lines in the cache coherency domain of the calling
|
|
CPU.
|
|
|
|
Flushes the cache lines specified by Address and Length. If Address is not aligned
|
|
on a cache line boundary, then entire cache line containing Address is flushed.
|
|
If Address + Length is not aligned on a cache line boundary, then the entire cache
|
|
line containing Address + Length - 1 is flushed. This function may choose to flush
|
|
the entire cache if that is more efficient than flushing the specified range. If
|
|
Length is 0, the no cache lines are flushed.
|
|
|
|
@param[in] Address The base address of the lines to invalidate.
|
|
|
|
@param[in] Length The number of bytes to invalidate from the cache.
