  • 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 the PE that executes this System instruction.

Field descriptions

This instruction has no applicable fields.

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

Executing the TLBI ALLE3 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 ALLE3{, <Xt>}

if PSTATE.EL == EL0 then
elsif PSTATE.EL == EL1 then
elsif PSTATE.EL == EL2 then
elsif PSTATE.EL == EL3 then
