TLBIMVAALIS, TLB Invalidate by VA, All ASID, Last level, Inner Shareable

The TLBIMVAALIS characteristics are:

Purpose

Invalidate all cached copies of translation table entries from TLBs that meet the following requirements:

• The entry is a stage 1 translation table entry, from the final level of the translation table walk.
• The entry would be used to translate the specified address.
• If EL2 is implemented and enabled in the current Security state, the entry would be used with the current VMID.

From the entries that match these requirements, the entries that are invalidated are required for the following translation regime:

• If executed at Secure EL1 when EL3 is using AArch64, the Secure EL1&0 translation regime.
• If executed in Secure state when EL3 is using AArch32, the Secure PL1&0 translation regime.
• If executed in Non-secure state, the Non-secure PL1&0 translation regime.

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

Configuration

This instruction is present only when AArch32 is supported at any Exception level. Otherwise, direct accesses to TLBIMVAALIS are UNKNOWN.

Attributes

TLBIMVAALIS is a 32-bit System instruction.

Field descriptions

The TLBIMVAALIS input value bit assignments are:

VA, bits [31:12]

Virtual address to match. Any unlocked TLB entries that match the VA will be affected by this System instruction, regardless of the ASID.

Bits [11:0]

Reserved, RES0.
