TLBI ALLE3OS, TLB Invalidate All, EL3, Outer Shareable

The TLBI ALLE3OS characteristics are:

Purpose

If EL3 is implemented, invalidates cached copies of translation table entries from TLBs that meet all the following requirements:

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

Configuration

This instruction is present only when ARMv8.4-TLBI is implemented. Otherwise, direct accesses to TLBI ALLE3OS are UNDEFINED.

Attributes

TLBI ALLE3OS is a 64-bit System instruction.

Field descriptions

TLBI ALLE3OS ignores the value in the register specified by the instruction encoding. Software does not have to write a value to the register before issuing this instruction.

Executing the TLBI ALLE3OS instruction

Accesses to this instruction use the following encodings:

TLBI ALLE3OS{, <Xt>}

op0op1CRnCRmop2Rt
0b010b1100b10000b00010b0000b11111

if PSTATE.EL == EL0 then UNDEFINED; elsif PSTATE.EL == EL1 then UNDEFINED; elsif PSTATE.EL == EL2 then UNDEFINED; elsif PSTATE.EL == EL3 then TLBI_ALLE3OS();
