Translation Lookaside Buffer Invalidate All
All TLB entries ← invalid
The entire translation lookaside buffer (TLB) is invalidated (that
is, all entries are removed). The TLB is invalidated regardless of
the settings of MSR[IR] and MSR[DR]. The invalidation is done
without reference to the SLB, segment table, or segment
registers. This instruction does not cause the entries to be
invalidated in other processors. This is a supervisor-level
instructon.
Other registers altered:
None
