Identify TLB entries corresponding to VPS
Each such TLB entry
contains an entry corresponding to EA, that entry is made invalid
(that is, removed from the TLB).
Multiprocessing implementations (for example, the 601, and
604) send a tlbie address-only broadcast over the address bus
to tell other processors to invalidate the same TLB entry in their
TLBs.
The TLB search is done regardless of the settings of MSR[IR]
and MSR[DR]. The search is done based on a portion of the
logical page number within a segment, without reference to the
segment registers. All entries matching the search criteria are
invalidated.
Block address translation for EA, if any, is ignored. This is a
supervisor-level instruction.
