For Standard TLB configuration (Config.MT=1):

TLBINV invalidates a set of TLB entries based on ASID. The virtual address is
ignored in the entry match. TLB entries which have their G bit set to 1 are not
modified.

TLBINVF causes all entries to be invalidated.

Single TLB entry can be marked as invalid on TLB entry write by having
EntryHi.EHINV set to 1.
