The TLBI ALLE3OS characteristics are:
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.
This instruction is present only when ARMv8.4-TLBI is implemented. Otherwise, direct accesses to TLBI ALLE3OS are UNDEFINED.
TLBI ALLE3OS is a 64-bit System instruction.
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.
Accesses to this instruction use the following encodings:
op0 | op1 | CRn | CRm | op2 | Rt |
---|---|---|---|---|---|
0b01 | 0b110 | 0b1000 | 0b0001 | 0b000 | 0b11111 |
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();
