At least the way its implemented currently, invalidating FMRs individually is likely to be faster than regular MRs, especially on memfree silicon: you need at least 2 roundtrips to hardware to create an MR, FMR can be mapped with memory writes. Invalidating both an MR and FMR needs one command in both cases. -- Michael S.
