The TLBI ASIDE1OS characteristics are:
Invalidates cached copies of translation table entries from TLBs that meet all the following requirements:
The entry is a stage 1 translation table entry.
The entry would be used for the specified ASID, and either:
Is from a level of lookup above the final level.
Is a non-global entry from the final level of lookup.
When EL2 is implemented and enabled in the current Security state:
When EL2 is not implemented or is disabled in the current Security state, the entry would be required to translate an address using the EL1&0 translation regime.
The invalidation applies to all PEs in the same Outer Shareable shareability domain as the PE that executes this instructions.
This instruction is present only when ARMv8.4-TLBI is implemented. Otherwise, direct accesses to TLBI ASIDE1OS are UNDEFINED.
TLBI ASIDE1OS is a 64-bit System instruction.
The TLBI ASIDE1OS input value bit assignments are:

ASID value to match. Any appropriate TLB entries that match the ASID values will be affected by this operation.
If the implementation supports 16 bits of ASID, but only 8 bits are being used in the context being invalidated, the upper bits are RES0.
Reserved, RES0.
Accesses to this instruction use the following encodings:
