| H A D | tlb.h | d17d8f9dedb9dd76fd540a5c497101529d9eb25a Thu Jul 31 10:40:59 CDT 2014 Dave Hansen <dave@sr71.net> x86/mm: Add tracepoints for TLB flushes
We don't have any good way to figure out what kinds of flushes
are being attempted. Right now, we can try to use the vm
counters, but those only tell us what we actually did with the
hardware (one-by-one vs full) and don't tell us what was actually
_requested_.
This allows us to select out "interesting" TLB flushes that we
might want to optimize (like the ranged ones) and ignore the ones
that we have very little control over (the ones at context
switch).
