Notes The operation must typically perform the following: # Globally invalidate TLB or TLBs # Globally clean and invalidate all caches # Drain write buffer Note that the implementation is not expected to deal with changes to pages which are in active use by interrupt routines. This operation should typically be used when a large number of cacheable pages have had their attributes changed in a way which will affect cache behaviour. h4. See also * [[OS_MMUControl 2]]
