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 entry is a stage 1 translation table entry, from any level of the translation table walk.

  • The entry would be required to translate an address using the EL3 translation regime.

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 FEAT_TLBIOS is implemented. Otherwise, direct accesses to TLBI ALLE3OS are UNDEFINED.

Attributes

TLBI ALLE3OS is a 64-bit System instruction.

Field descriptions

This instruction has no applicable fields.

The value in the register specified by <Xt> is ignored.

Executing the TLBI ALLE3OS instruction

When executing this instruction Xt should be encoded as 0b11111. If the Xt field is not set to 0b11111, it is CONSTRAINED UNPREDICTABLE whether:

  • The instruction is UNDEFINED.

  • The instruction behaves as if the Xt field is set to 0b11111.

Accesses to this instruction use the following encodings:

TLBI ALLE3OS{, <Xt>}
