TLBIMVAHIS, TLB Invalidate by VA, Hyp mode, Inner Shareable

The TLBIMVAHIS characteristics are:

Purpose

If EL2 is implemented, invalidate all cached copies of translation table entries from TLBs that are from any level of the translation table walk that would be required for the Non-secure EL2 translation regime and used to translate the specified address.

The invalidation applies to all PEs in the same Inner Shareable shareability domain as the PE that executes this System instruction.

Configuration

This instruction is present only when EL2 is capable of using AArch32. Otherwise, direct accesses to TLBIMVAHIS are UNDEFINED.

Attributes

TLBIMVAHIS is a 32-bit System instruction.

VARES0

VA, bits [31:12]

Virtual address to match. Any TLB entries that match the ASID value and VA value will be affected by this System instruction.

Bits [11:0]

Reserved, RES0.

Executing TLBIMVAHIS

If this instruction is executed in a Secure privileged mode other than Monitor mode, then the behavior is CONSTRAINED UNPREDICTABLE, and one of the following behaviors must occur:

Accesses to this instruction use the following encodings in the System instruction encoding space:

MCR{<c>}{<q>} <coproc>, {#}<opc1>, <Rt>, <CRn>, <CRm>{, {#}<opc2>}
